TI The Influence of Chemistry, Production and Community Composition on Leaf Litter Decomposition Under Elevated Atmospheric CO2 and Tropospheric O-3 in a Northern Hardwood Ecosystem SO ECOSYSTEMS LA English DT Article DE condensed tannins; FACE; global change; lignin; litter productivity; mean residence time; plant community composition; soluble phenolics; soil carbon storage ID SOIL MICROBIAL COMMUNITY; PAPER BIRCH COMMUNITIES; CARBON-DIOXIDE; TREMBLING ASPEN; AND/OR O-3; NITROGEN DEPOSITION; YOUNG STANDS; OZONE; FOREST; PINE AB We examined the effects of elevated CO2 and O-3 and their interaction on leaf litter chemistry and decomposition in pure stands of aspen (Populus tremuloides) and mixed stands of birch (Betula papyrifera) and aspen at the Aspen Free Air CO2 Enrichment (FACE) experiment. A 935-day in situ incubation study was performed using litterbags filled with naturally senesced leaf litter. We found that elevated CO2 had no overall effects on litter decomposition rates, whereas elevated O-3 reduced litter mass loss (-13%) in the first year. The effect of O-3 on mass loss disappeared in the second year. For aspen litter but not mixed birch-aspen litter, decomposition rates were negatively correlated with initial concentrations of condensed tannins and phenolics. Most soluble components (94% of soluble sugars, 99% of condensed tannins, and 91% of soluble phenolics) and any treatment effects on their initial concentrations disappeared rapidly. However, the mean residence time (MRT) of birch-aspen litter (3.1 years) was significantly lower than that of aspen litter (4.8 years). Further, because of variation in total litterfall, total litter mass, C, lignin and N remaining in the ecosystem was highest under elevated CO2 and lowest under elevated O-3 during the incubation period. Our results indicate that elevated CO2 and O-3 can alter short-term litter decomposition dynamics, but longer-term effects will depend more on indirect effects mediated through changes in forest community composition. Treatment effects on soluble components are likely to influence cyclical microbial processes and carbon pulses in the ecosystem only when coupled with increased (CO2) or decreased (O-3) litter inputs.

Fire risk abatement on multi-owner landscapes containing flammable but fire-dependent ecosystems epitomizes the complexities of managing public lands. We report a case study that applies a landscape disturbance and succession model (LANDIS) to evaluate the relative effectiveness of four alternative fire mitigation strategies on the Chequamegon-Nicolet National Forest (Wisconsin, USA), where fire-dependent pine and oak systems overlap with a rapidly developing wildland-urban interface (WUI). We incorporated timber management of the current forest plan and fire characteristics (ignition patterns, fire sizes, and fuel-specific fire spread rates) typical for the region under current fire suppression policies, using a combination of previously published fire analyses and interactive expert opinion from the national forest. Of the fire mitigation strategies evaluated, reduction of ignitions caused by debris-burning had the strongest influence on fire risk, followed by the strategic redistribution of risky forest types away from the high ignition rates of the WUI. Other treatments (fire breaks and reducing roadside ignitions) were less effective. Escaped fires, although rare, introduced significant uncertainty in the simulations and are expected to complicate fire management planning. Simulations also show that long-term maintenance of fire-dependent communities (that is, pine and oak) representing the greatest forest fire risk requires active management. Resolving conflict between the survival of fire-dependent communities that are regionally declining and continued rural development requires strategic planning that accounts for multi-owner activities.

We assessed disease incidence and related mortality of a recent outbreak of fungal stem cankers on A. tenuifolia across three regions in Alaska during the 2005 growing season, and determined the impacts on N-fixation rates, nodule biomass, and stand-level N-fixation inputs. The highest percentage of ramets colonized or dead with canker was found on Tanana River plots, suggesting the epidemic is most severe in the Fairbanks region. A positive relationship between % basal area loss to canker and % canopy loss provides a simple means for assessing stand-level mortality associated with disease in the field. Although specific N-fixation (SNF) rates were not influenced by canker disease incidence of individual genets, live nodule biomass beneath alder canopies was inversely correlated with the percentage of ramets dead or with main ramet canker. Variations in SNF and live nodule biomass translated to differences in N-fixation inputs, which ranged from 22 to 107 kg N ha(-1) y(-1) across study regions. Nodule biomass was reduced by incidence of canker disease and related mortality an average of 24% across all sites, which translates to N input reductions of 8, 16, and 33 kg N ha(-1) y(-1) for the three regions, respectively. During the 2008 growing season, we resurveyed the Tanana River plots and found that of the ramets larger than 4-cm diameter having main ramet canker in 2005, 74% are now dead; and for those without main ramet canker in 2005, 25% have developed main ramet canker, and 8% are dead. Thus, it is likely that N-fixation inputs have declined further below what we estimated for 2005.

TI Ecosystem and Restoration Consequences of Invasive Woody Species Removal in Hawaiian Lowland Wet Forest SO ECOSYSTEMS LA English DT Article DE aboveground biomass; Metrosideros polymorpha; non-native species; nutrient cycling; productivity; resource availability ID SOUTH-AFRICAN FYNBOS; METROSIDEROS-POLYMORPHA; TROPICAL FORESTS; NATURAL-ABUNDANCE; AVIAN MALARIA; RAIN-FOREST; NUTRIENT; DECOMPOSITION; AVAILABILITY; DIVERSITY AB A removal experiment was used to examine the restoration potential of a lowland wet forest in Hawaii, a remnant forest type that has been heavily invaded by non-native species and in which there is very little native species regeneration. All non-native woody and herbaceous biomass (approximately 45% of basal area) was removed in four 100-m(2) removal plots; plots were followed for a three-year period. Removal plots had a lower leaf area index, higher air temperatures, higher afternoon soil temperatures, and lower relative humidity than control plots. Removal plots had 40% less litterfall mass and similarly reduced nutrient inputs. Leaf litter decomposition rates were much slower in the removal plots, due more to site quality than litter quality. However, soil N and P were not different between treatments. Native species had a distinct suite of leaf traits (greater integrated water use efficiency, lower mass-based leaf nutrient concentrations, and lower specific leaf area). Despite major environmental changes in the removal plots, native species' diameter growth and litterfall productivity were not significantly greater after removal, testifying to the slow response capabilities of native Hawaiian trees. Our results are consistent with the expectation that native species are conservative in regards to resource use and may not strongly respond to canopy removal, at least at the adult stage. Management strategies will have to incorporate the slow growth rate of Hawaiian species and the fact that weeding may be required to suppress expansion and nutrient inputs of introduced species.

A systematic study was carried out to determine imidacloprid resistance dynamics and cross-resistance. Data collected from a 3-year study (2005-2007) showed that in 2005, the resistance levels in Nanning (Guangxi), Haiyan (Zhejiang), and Nanjing and Tongzhou (Jiangsu) populations ranged from 200- to 799-fold compared with the susceptible strain. However, the resistance levels decreased to 135- to 233-fold in 2007, after reduced application of the chemical. A laboratory population was challenged with imidacloprid in successive generations. After 23 generations, the resistance ratio had increased from 200- to 1 298-fold. Continuous selection with imidacloprid could increase the resistance level even more than has already been developed in the population. Stopping selection with imidacloprid led to a rapid decrease of resistance from 759- to 114-fold after 17 generations. Resistance levels then became stable without decreasing any further. A similar result was also obtained from a study involving a field population (resistance ratio = 625-fold) collected from Tongzhou. At first, the population showed a rapid decrease in resistance right after imidacloprid selection was stopped, and then the resistance stabilized at a level of 105-129-fold. More interestingly, resistance increased again when selection was resumed. In addition, the resistant strain selected with imidacloprid showed substantial cross-resistance to imidaclothiz, thiacloprid, and acetamiprid, and slight levels of cross-resistance to dinotefuran and thiamethoxam, but no obvious cross-resistance to nitenpyram, buprofezin, and fipronil. The information from this study is valuable for formulating resistance-management strategies against N. lugens.

We evaluated sexual behaviour, mating competitiveness of methoprene-treated males, and female readiness to mate after methoprene-treatment in field cages. The study involved two strains of A. fraterculus from Argentina and Peru, which show several polymorphisms in relation to their sexual behaviour. We also analyzed whether methoprene treatment affected male and/or female behaviour in the same way in these two strains. Methoprene-treated males were equally competitive with untreated mature males, and became sexually competitive 6 days after emergence (3-4 days earlier than untreated males). In contrast, methoprene did not induce sexual maturation in females or, at least, it did not induce a higher rate of mating in 7-day-old females. These results were observed both for the Argentina and the Peru strains. Altogether, our results indicate that methoprene treatment produces sexually competitive males in field cages. In the absence of a genetic sexing system, and when sterile males and females of A. fraterculus are released simultaneously, the fact that females do not respond as do males to the methoprene treatment acts as a physiological sexing effect. Therefore, in the presence of mainly sexually immature sterile females, released sexually mature sterile males would have to disperse in search of wild fertile females, thereby greatly reducing matings among the released sterile insects and thus enhancing sterile insect technique efficiency.

We found that a freshly cut fruit of an eggplant cultivar [Solanum melongena L. cv. Long Purple Oriental (Solanaceae)] selectively attracted and provoked voracious feeding behavior in adult B. latifrons males (but not in females) in an indoor test. One of the male-specific attractants/feeding stimulants in eggplant was identified as 3-hydroxy-alpha-ionone. Sexually mature males that fed on the eggplant pulp selectively accumulated a series of 3-oxygenated alpha-ionone/alpha-ionol analogs (e.g., 3-oxo-alpha-ionol and 3-oxo-7,8-dihydro-alpha-ionol) in the rectal gland, a suspected pheromone reservoir in male flies. Males fed on synthetic 3-hydroxy-alpha-ionone, 3-oxo-alpha-ionol, or 3-oxo-alpha-ionone partially biotransformed the compounds into 3-oxo-alpha-ionol, 3-oxo-alpha-ionone, and 3-oxo-7,8-dihydro-alpha-ionol and sequestered substantial quantities (as high as 5 mu g/gland as a mixture) in a similar ratio in the rectal gland within 6 h after ingestion. These results suggest that the rectal sequestrates may serve as a sex pheromone similar to other Bactrocera species that use phenylpropanoid volatiles to attract conspecific females.

Epidemiological models typically assume that birth and death rates of pathogen-free and inoculative vectors are equal, an assumption that is not true for all pathosystems. Here, a series of simple and general epidemiological models were used to explore how assumptions about birth and death rates of vectors based on their infectivity status influence disease incidence. With fixed death rate of pathogen-free vectors, increasing the death rate of inoculative vectors reduced vector density, the proportion of vectors that were inoculative, and the proportion of hosts infected. This effect was mediated by acquisition rate. Specifically, increasing the acquisition rate increased the proportion of vectors that were inoculative, thereby increasing the proportion of the vector population that experienced the increased death rate. With fixed birth rate of pathogen-free vectors, variation in birth rate of inoculative vectors had little influence on disease incidence provided that the birth rate of pathogen-free vectors was much greater than their death rate. However, when the birth rate of pathogen-free vectors was only slightly greater than their death rate, large increases in the birth rate of inoculative vectors increased total vector density and disease incidence. The results indicate that assumptions about birth and death rates of vectors based on infectivity status can have important effects on the vector population that in turn affects disease incidence.

K. Koch)] host is poorly understood. Laboratory experiments were conducted on the settling behavior of the black pecan aphid, when provided chlorotic pecan leaf discs resulting from previous black pecan aphid feeding and nonchlorotic leaf discs, under a normal photoperiod and constant dark. Additionally, aphid development from the first instar to the adult stage was examined when nymphs were either allowed to feed on the same leaf disc or moved daily to a new, nondamaged, same age leaf disc. After 24 h, a significantly higher percentage of black pecan aphids settled on chlorotic than on nonchlorotic leaf discs, regardless of photoperiod. When starting from the first instar, nymphs that were prevented from inducing leaf chlorosis by moving daily to new, same-age leaf discs took similar to 5 d longer to complete development, had a shorter body length, and had higher mortality than when aphids remained on the same leaf disc. These results show that black pecan aphid-induced leaf chlorosis plays an important role in the interaction of the black pecan aphid with its pecan host.

The electrophysiological and behavioral activities of the four bark beetle pheromones, frontalin, exo-brevicomin, trans-verbenol, and cis-verbenol, singly or in combination with host-produced kairomones, were tested on red turpentine beetles. Both sexes showed a consistent electrophysiological response to the four test compounds. In Y-tube olfactometer bioassays, walking red turpentine beetles selected the host compound (+)-3-carene over any of the test compounds, but significantly higher numbers chose each tested pheromone over a blank control. The four compounds, tested singly or in combination, were not attractive to red turpentine beetles in field trapping studies in 2006 and 2007 and also did not significantly increase trap catch when combined with (+) -3-carene. Frontalin, alone or in combination with exo-brevicomin and trans-verbenol, significantly reduced the attractiveness of (+) -3-carene in 2006 but not in 2007. The possible roles of the pheromones in host and mate finding and selection are discussed.

Ecologists and managers use these models to predict animal distributions for gap analysis and conservation planning. Critics, however, have suggested that the models are overly simplistic and inaccurate. We reviewed the use of cover-type models including assessing their error rates, diagnosing the problems with these models, and determining how they should best be used by managers. To determine models' accuracy rates, we conducted a meta-analysis of 35 studies in which cover-type models were tested against data on animal occurrences. Models had a mean accuracy rate of 0.71 +/- A 0.18 (SD). Rates of commission error averaged 0.20 +/- A 0.16, and omission errors averaged 0.09 +/- A 0.11. A review of the effects of errors in conservation planning suggests that the observed error rates were high enough to call into question any management decisions based on these models. Reasons for the high error rates of cover-type models include the fallibility of expert opinion, the fact that the models oversimplify how animals actually use habitats, and the dynamic nature of animal populations. Given the high rate of errors in cover-type models, any conclusions based on them should be taken with extreme caution. We suggest that these models are best used as coarse filters to identify locations for further study in the field.

This increase corresponds to significant advances in theory for step-pools in recent years. The need for step-pools in stream restoration arises as urban development encroaches into steep terrain in response to population pressures, as stream channels in lower-gradient areas require stabilization due to hydrological alterations associated with land-use changes, and as step-pools are recognized for their potential to enhance stream habitats. Despite an increasingly voluminous literature and great demand for restoration using step-pool sequences, however, the link between theory and practice is limited. In this article, we present four unique cases of stream restoration using step-pools, including the evolution of the approaches, the project designs, and adjustments in the system following restoration. Baxter Creek in El Cerrito, California demonstrates an early application of artificial step-pools in which natural adjustments occurred toward geomorphic stability and ecological improvement. Restoration of East Alamo Creek in a large residential development near San Ramon, California illustrates an example of step-pools increasingly used in locations where such a channel form would not naturally occur. Construction of a step-pool channel in Karnowsky Creek within the Siuslaw National Forest, Oregon overcame constraints posed by access and the type and availability of materials; the placement of logs allowed natural scouring below steps. Dry Canyon Creek on the property of the Mountains Restoration Trust in Calabasas, California afforded a somewhat experimental approach to designing step-pools, allowing observation and learning in the future. These cases demonstrate how theories and relationships developed for step-pool sequences over the past two decades have been applied in real-world settings. The lessons from these examples enable us to develop considerations useful for deriving an appropriate course of design, approval, and construction of artificial step-pool systems. They also raise additional fundamental questions concerning appropriate strategies for restoration of step-pool streams. Outstanding challenges are highlighted as opportunities for continuing theoretical work. C1 [Chin, Anne] Texas A&M Univ, Coll Geosci, Dept Geog, College Stn, TX 77843 USA.

We surveyed woodland salamander occurrence from June-August 2006 at 33 gas well sites in the Monongahela National Forest, West Virginia. We used an information-theoretic approach to test nine a priori models explaining landscape-scale effects on woodland salamander capture proportion within 20 m of field edge. Salamander capture proportion was greater within 0-60 m than 61-100 m of field edges. Similarly, available coarse woody debris proportion was greater within 0-60 m than 61-100 m of field edge. Our ASPECT model, that incorporated the single variable aspect, received the strongest support for explaining landscape-scale effects on salamander capture proportion within 20 m of opening edge. The ASPECT model indicated that fewer salamanders occurred within 20 m of opening edges on drier, hotter southwestern aspects than in moister, cooler northeastern aspects. Our results suggest that forest habitat adjacent to maintained edges and with sufficient cover still can provide suitable habitat for woodland salamander species in central Appalachian mixed mesophytic and northern hardwood forests. Additionally, our modeling results support the contention that edge effects are more severe on southwesterly aspects. These results underscore the importance of distinguishing among different edge types as well as placing survey locations within a landscape context when investigating edge impacts on woodland salamanders.

In Upland cotton (Gossypium hirsutum L.), photoperiodic sensitivity is a major obstacle in the utilization of primitive accessions in breeding programs. Quantitative trait loci (QTLs) analysis was conducted in two F(2) populations from the crosses between a day-neutral cultivar Deltapine 61 (DPL61) and two photoperiod sensitive G. hirsutum accessions (T1107 and T1354). Node of first fruiting branch (NFB) was used to measure relative time of flowering. Different flowering time genetic patterns were observed in the two populations. Two QTLs were found across five scoring dates, accounting 28.5 (qNFB-c21-1) and 15.9% (qNFB-c25-1) of the phenotypic variation at the last scoring date in Pop. 1107 (DPL61 by T1107); whereas, one major QTL (qNFB-c25-1) can be detected across five scoring dates, explained 63.5% of the phenotypic variation at the last scoring date in Pop. 1354 (DPL61 by T1354). QTLs with minor effects appeared at various scoring date(s), indicating their roles in regulating flowering at a lower or higher node number. Genetic segregation analysis and QTL mapping results provide further information on the mechanisms of cotton photoperiodic sensitivity.

Sclerotinia minor Jagger (S. minor), the causal agent of Sclerotinia blight, is a major threat to peanut production in the Southwestern US, Virginia and North Carolina. Although information on the variability of morphological traits associated with Sclerotinia blight resistance is plentiful, no molecular markers associated with resistance have been reported. The identification of markers would greatly assist peanut geneticists in selecting genotypes to be used in breeding programs. The main objective of this work was to use simple sequence repeat (SSR) primers previously reported for peanut to identify a molecular marker associated with resistance to S. minor. Out of 16 primer pairs used to examine peanut genomic DNA from 39 different genotypes, one pair produced bands at approximately 145 and 100 bp, consistent with either S. minor resistance or susceptibility, respectively. Cloning and sequencing of these bands revealed the region is well conserved among all genotypes tested with the exception of the length of the SSR region, which varies with disease resistance levels. This is the first report of a molecular marker associated with resistance to Sclerotinia blight in peanut. The identification of this marker and development of a PCR-based screening method will prove to be extremely useful to peanut breeders in screening germplasm collections and segregating populations as well as in pyramiding S. minor resistance with other desirable traits into superior peanut lines.

Subjects/Methods: A cross-sectional study of 1762 participants of the Framingham Offspring Study (919 women; mean age 59 years). Vitamin K status was measured as plasma phylloquinone and serum percent undercarboxylated osteocalcin (ucOC), and vitamin D was measured using plasma 25-hydroxyvitamin D (25(OH)D). Associations between vitamin K status and vitamin D status with biologically plausible nongenetic factors were assessed using stepwise regression. Heritability and linkage were determined using Sequential Oligogenic Linkage Analysis Routines (SOLAR). Results: Nongenetic factors accounted for 20.1 and 12.3% of the variability in plasma phylloquinone in men and women respectively, with triglycerides and phylloquinone intake being the primary correlates. In men 12.2% and in women 14.6% of the variability in %ucOC was explained by nongenetic factors in our models. Heritability estimates for these vitamin K status biomarkers were nonsignificant. Season, vitamin D intake, high-density lipoprotein (HDL) cholesterol and waist circumference explained 24.7% (men) and 24.2% (women) of the variability in plasma 25(OH)D. Of the three vitamins examined, only 25(OH)D was significantly heritable (heritability estimate 28.8%, P < 0.01), but linkage analysis of 25(OH)D did not achieve genome- wide significance. Conclusions: Variability in biomarkers of vitamin K status was attributed to nongenetic factors, whereas plasma 25(OH)D was found to be significantly heritable. Further studies are warranted to investigate genetic loci influencing vitamin D status. C1 [Shea, M. K.; Jacques, P. F.; Ordovas, J. M.; Dawson-Hughes, B.; Booth, S.

We investigated the linearity of this response after consumption of 5 breakfast cereal test meals containing wheat and/or barley to provide varying amounts of soluble fiber, beta-glucan (0, 2.5, 5, 7.5 and 10 g). Seventeen normoglycemic, obese women at increased risk for insulin resistance consumed 5 test meals within a randomized cross-over design after consuming controlled diets for 2 days. Blood samples for glucose and insulin response were obtained prior to and 30, 60, 120 and 180 min after consuming the test meals. Consumption of 10 g of beta-glucan significantly reduced peak glucose response at 30 min and delayed the rate of glucose response. Area under the curve for 2 h-postprandial glycemic response was not affected by beta-glucan content. However, peak and area under the curve of insulin responses were significantly affected by the beta-glucan amount in an inverse linear relationship. These data suggest that acute consumption of 10 g of beta-glucan is able to induce physiologically beneficial effects on postprandial insulin responses in obese women at risk for insulin resistance.

A series of preliminary characterisations using a single susceptible host and four different R. solani isolates suggested the disease progression pattern was predictable. Two AG-4 isolates and a less virulent AG-2-2 isolate (W22) showed a comparable pattern of disease progression in the growth chamber where disease index values increased for the first 5-6 days, were relatively constant for the next 7-8 days, and declined thereafter. Seedlings inoculated with a highly virulent AG-2-2 isolate (R-1) under the same conditions showed similar patterns for the first 4 days post-inoculation; however disease index values continued to increase until seedling death at 13-14 days. Similar results were observed in the greenhouse, and a small expanded set of other germplasm lines were screened. One tested germplasm accession, EL51, survived seedling inoculation with R. solani AG-2-2 R-1, and its disease progress pattern was characterised. In a field seedling disease nursery artificially inoculated with R. solani AG-2-2 R-1, seedling persistence was high with EL51, but not with a susceptible hybrid. Identification of EL51 as a source of resistance to Rhizoctonia damping-off may allow investigations into the Beta vulgaris-Rhizoctonia solani pathosystem and add value in sugar beet breeding.

TI Short-term temporal changes of bare soil CO2 fluxes after tillage described by first-order decay models SO EUROPEAN JOURNAL OF SOIL SCIENCE LA English DT Article ID ORGANIC-MATTER DYNAMICS; NATURAL C-13 ABUNDANCE; CARBON-DIOXIDE EFFLUX; CROPPING SYSTEMS; SOUTHERN BRAZIL; SEQUESTRATION; VALIDATION; MANAGEMENT; AGGREGATE; TURNOVER AB To further understand the impact of tillage on carbon dioxide (CO2) emission, we compare the performance of two conceptual models that describe CO2 emission after tillage as a function of the non-tilled emission plus a correction resulting from the tillage disturbance. The models assume that C in the readily decomposable organic matter follows a first-order reaction kinetics equation as dCsoil(t)/dt = -kC(soil)d(t) and that soil C-CO2 emission is proportional to the C decay rate in soil, where C-soil(t) is the available labile soil C (g m(-2)) at any time (t) and k is the decay constant (time(-1)). Two possible relationships are derived between non-tilled (FNT) and tilled (F-T) soil fluxes F-T F-NT + a(1) e(-a2t) (model 1) and F-T a(3)F(NT) e(-a4t) (model 2), where t is time after tillage. The difference between these two models comes from an assumption related to the k factor of labile C in the tilled plot and its similarity to the k factor of labile C in the non-till plot. Statistical. t of experimental data to conceptual models showed good agreement between predicted and observed CO2 fluxes based on the index of agreement (d-index) and with model efficiency as large as 0.97. Comparisons reveal that model 2, where all C pools are assigned the same k factor, produces a better statistical. t than model 1. The advantage of this modelling approach is that temporal variability of tillage-induced emissions can be described by a simple analytical function that includes the non-tilled emission plus an exponential term, which is dependent upon tillage and environmental conditions.

Xanthosine treatment was previously shown to promote expansion of hepatic stem cells in vitro. The objective of this study was to determine if in vivo treatment with xanthosine can increase the mammary stem cell population. Xanthosine was infused into the right mammary glands of four female Holstein calves for 5 consecutive days. Immediately after each xanthosine treatment, calves were injected intravenously with 5-bromo-2-deoxyuridine (BrdU). Forty days after the final treatment, calves were euthanized and mammary tissue harvested. BrdU-label retaining epithelial cells (LREC) were detected immunohistochemically and quantified. Retention of BrdU was used as a marker for putative bovine mammary stem cells. Infusion of xanthosine into the bovine mammary gland significantly increased the number of LREC in treated glands compared to contralateral control glands (P < 0.05). LREC averaged 0.4% of epithelial cells in control glands and 0.8% in xanthosine-treated glands. The increase in LREC in xanthosine-treated glands was supported by a concomitant increase in telomerase activity (P < 0.01) and a correlation between LREC and telomerase (P < 0.05; r(2) = 0.7). Data indicate that in vivo treatment with xanthosine can be used to increase the number of mammary stem cells. This is the first demonstration of an in vivo treatment to increase the endogenous population of mammary stem cells, with utility for biomedical research and dairy management.

While mechanisms underlying astrocyte swelling are likely multifactorial, oxidative stress and mitochondrial dysfunction are hypothesized to contribute to such swelling. We investigated the protective effects of cinnamon polyphenol extract (CPE) that has anti-oxidant and insulin-potentiating effects on cell swelling and depolarization of the inner mitochondrial membrane potential (Delta psi(m)) in ischemic injury. C6 glial cells were subjected to oxygen-glucose deprivation (OGD) and cell volume determined using the 3-O-methyl-[(3)H]-glucose method at 90 min after the end of OGD. When compared with controls, OGD increased cell volume by 34%. This increase was blocked by CPE or insulin but not by blockers of oxidative/nitrosative stress including vitamin E, resveratrol, N-nitro-L-arginine methyl ester (L-NAME) or uric acid. Mitochondrial dysfunction, a key component of ischemic injury, contributes to cell swelling. Changes in Delta psi(m) were assessed at the end of OGD with tetramethylrhodamine ethyl ester (TMRE), a potentiometric dye. OGD induced a 39% decline in Delta psi(m) and this decline was blocked by CPE as well as insulin. To test the involvement of the mitochondrial permeability transition (mPT), we used Cyclosporin A (CsA), ail immunosuppressant and a blocker of the mPF pore. CsA blocked cell swelling and the decline in Delta psi(m) but FK506, an immunosuppressant that does not block the mPT, did not. Our results show that CPE reduces OGD-induced cell swelling as well as the decline in Delta psi(m) in cultures and some of its protective effects may be through inhibiting the mPT.

We measured the tensile properties as a function of plasticizer composition, and analyzed the specific effect of each individual component on tensile properties. We found that it is the unrecovered alkyl esters that largely determine the tensile properties, and that BCS can be successfully used to plasticize cast gelatin films as long as the BCS contains 11 parts by weight, or less, of unrecovered alkyl esters per 100 parts glycerol.

In trial I, catfish were immunized intraperitoneally (IP) with: 1) 1% formal in-inactivated trophonts, 2) 3% formalin-inactivated trophonts and 3) freeze-thawed trophonts. Positive and negative control catfish were immunized with live theronts and 5% bovine serum albumin (BSA), respectively. At day 14, 28 and 50 post-immunizations. no statistical difference was noted in serum or cutaneous anti-Ich antibody titers to formalin-inactivated trophonts or freeze-thawed trophonts. The survival of catfish challenged with live theronts ranged from 33.3% to 43.3% for the formal in-inactivated or freeze-thawed trophonts at 50 d post-immunization. The survival of catfish immunized with live theront and BSA was 93.3 and 0%, respectively. In trial 11, catfish were IP immunized with sonicated trophonts at doses of 1) 5 trophonts or 10.2 mu g protein g(-1) fish, 2) 10 trophonts or 20.4 mu g protein g(-1) fish, 3) 20 trophonts or 40.8 mu g protein g(-1) fish, and 4) 5% BSA as the control. Fish immunized with 10 or 20 trophonts g(-1) fish showed highest serum (1/210 to 1/480) and cutaneous antibody titers (1/48 to 1/52), respectively, at 22 d post-immunization and survival (63.3-60.0%). The fish immunized with 5 trophonts g(-1) fish had titers of 1/52 and 1/12 for serum and cutaneous antibody and survival of 23.3%. BSA immunized catfish had background titers and a survival of 6.7%. There was a significant correlation between doses of sonicated trophonts used to immunize and catfish survival (correlation coefficient = 0.859, p < 0.01). These results indicate that doses of sonicated trophonts, but not formalin-inactivated or freeze-thawed trophonts; provided both serum and cutaneous antibody responses and survival to live trophont challenge.

Quantitative PCR (qPCR) experiments were conducted by amplifying an SSIIb-3 endogenous control and an NK603 transgene in untreated, sonicated, and heat treated samples. qPCR reactions on sonicated DNA samples, based on A(260) quantification, provided 0.125%, 1.14% and 2.15% NK603; while heat treated samples, provided results of 0.128%, 1.42%, and 2.73% NK603. qPCR reactions on sonicated DNA samples, based on the fluorescent dye method, provided results of 0.18%, 0.861% and 1.74% NK603; while heat treated DNA samples, provided results of 0.18%, 1.02%, and 2.16% NK603. The data suggested that fluorescent dye-based quantifications yielded more accurate determinations of the percent genetically engineered (GM) content at higher concentrations, most likely because fluorescent dye quantifications resulted in additional copies of template added into the qPCR. The data in this study suggested that neither fluorescent dye nor spectrophotometric methods of quantification on highly degraded DNA translated into concordant measurements of qPCR amplifiable DNA and accurate Q values.

Outgrowth of the spores was measured as lag phase duration (LPD). Replication of vegetative cells was measured in terms of growth rate (GR) and maximum population density (MPD). Spore inactivation was recorded as inactivation rate and percent reduction in viable count. In general, spore viability decreased at low and high temperatures and increased at moderate temperatures. At 0 and 5 degrees C, a 60-100% reduction in spore viability was seen within 2-3 weeks in WE and YSU, 0-30% in YSA, and 50-100% in EW. At -20 degrees C, however, no drop in spore titer was observed in YSU and EW but a 20% drop in titer was seen in YSA and 50% in WE within 2-3 weeks. At high temperatures, WE, EW, and YSA produced a 20-50% drop in the spore titer within 1-4 h whereas YSU showed 100% inactivation within 0.75 h. At moderate storage temperatures, as the temperature increased from 15 to 40 degrees C, LPD decreased from 13.5 to 0.75 h and MPD reached 0.27-2.2 x 10(9) CFU/ml in YSU and WE, respectively. Markedly lower growth was observed in YSA (LPD = 24-270 h, MPD = 9 x 10(5) CFU/ml) and spores were inactivated completely within 1-6 h in EW. The survivability and inactivation data of B. anthracis in liquid egg products reported in this investigation will be helpful in developing risk assessment models on food biosecurity.

TI Genotyping Campylobacter jejuni by Comparative Genome Indexing: An Evaluation with Pulsed-Field Gel Electrophoresis and flaA SVR Sequencing SO FOODBORNE PATHOGENS AND DISEASE LA English DT Article ID DNA MICROARRAY TECHNOLOGY; SHORT VARIABLE REGION; UNITED-STATES; STRAINS; COLI; REVEALS; TOOL; IDENTIFICATION; PATHOGENS; PATTERNS AB Comparative genome indexing (CGI) using whole-genome DNA microarrays was evaluated as a means of genotyping Campylobacter jejuni relative to two standard methods, pulsed-field gel electrophoresis (PFGE) and flaA short variable region sequencing (flaA SVR typing). Thirty-six geographically diverse C. jejuni isolates were selected from a collection of cattle and chicken isolates. The BioNumerics (R) software program was used for cluster analysis of the data from all 36 isolates for each of the three typing methods. Comparative genome indexing assigned a unique type to each isolate while PFGE and flaA SVR distinguished 29 and 35 different types, respectively. The four common types identified by PFGE were also closely related by CGI, and the overall similarity of the CGI results to those for PFGE indicates the value of CGI as a more informative alternative to PFGE. While flaA SVR was very discriminative, the isolates were all highly similar (>78%) resulting in finer distinctions between isolates and fewer genotypic relations to CGI or PFGE. Campylobacter jejuni is one of the most common causative agents of bacterial gastroenteritis in the world. The development of CGI as a molecular typing tool for C. jejuni offers a highly effective and informative means of further understanding the epidemiology of this ubiquitous pathogen.

In this study 106 ail-positive pathogenic Y. enterocolitica isolates, previously recovered from 2793 swine fecal samples (3.8%) collected during National Animal Health Monitoring System's Swine 2000 study, were examined. The presence of the previously described virulence plasmid, expression of plasmid-associated virulence determinants, and serotype were correlated with genotype, expression of YopE protein, and antibiotic susceptibility. Pulsed-field gel electrophoresis using the enzyme XbaI showed that O:3 and O:5 isolates were highly clonal within a serotype regardless of geographic origin. Antimicrobial resistance profiles of 106 isolates of serotypes O:3 and O:5 were evaluated by agar disk diffusion methodology to 16 different antibiotics. All isolates were susceptible to 13 of the 16 tested antimicrobials; resistance was noted to ampicillin, cephalothin, and tetracycline. The presence of the ail gene, virulence plasmid, the expression of virulence determinants, and serotypes indicate that these isolates from U.S. swine are potentially capable of causing human foodborne illness.

The difference between the accumulation of internal steam pressure for small panels made in the laboratory and that of large commercial-sized panels makes it difficult to transfer knowledge gained from the laboratory to the commercial plant. The objective of this research project is 2-fold: first to investigate the effect of panel size on the initial development and subsequent dissipation of internal steam pressure during the hot-pressing cycle; and second, to learn how to improve of small laboratory presses to better mimic conditions experienced in the large press used in the manufacturing plant. In this study, changes in the panel size from 56 by 56 cm to 86 by 86) cm resulted in changes in the maximum steam pressure of up to 3.5-fold. A collar made from a steel rod was used, which prevented steam from escaping and helped to build higher internal steam pressure in smaller panels. Finally, the effects of a "burp" (briefly opening the press during the press cycle) or use of a forming screen were also studied in relation to internal steam pressure.

We examined the early (12-72 h) effects of photostimulation on mRNA transcripts and plasma levels of follicle stimulating hormone (FSH) and PRL in three-week old cockerels. In addition, the neuroendocrine influence of the compound, sulfamethazine (SMZ), known to enhance light-induced gonadal development in chicks, was studied when applied with or without long-day photostimulation. Both long day exposure and SMZ intake caused a rapid increase in FSH beta mRNA transcripts at Zeitgeber time 48 (ZT48), while only SMZ stimulated secretion of the hormone into plasma during the course of the study. In contrast to SMZ treatment, photostimulation was more effective at stimulating PRL mRNA transcripts and secretion of PRL. Results demonstrate a differential role of long day exposure and SMZ intake on the regulation of FSH and PRL synthesis and secretion and suggest that some effects of SMZ on gonadal development may be mediated by the pituitary.

Both autonomous and non-autonomous elements of the DcMaster family, residing in the carrot genome, were described previously. DcMaster elements were classified as members of the PIF/Harbinger superfamily. In the present paper we report on the identification of other groups of DcMaster-like elements. Beside the previously described, relatively highly abundant miniature inverted repeat element (MITE) family Krak (ca. 3,600 copies, ca. 80% intra-family similarity), three other families, i.e. 1.1 kb long KrakL1 (ca. 3,000 copies, ca. 98% intra-family similarity), 1.2 kb long KrakL2 (a single identified element, 71.1% similar to KrakL1 consensus), and 2.2 kb long Midi (few elements, 99% intra-family similarity), were revealed. The fact that all members within each of the newly found families were almost identical in their sequence suggests their very recent activity. The families differed in terms of their similarity to the canonical DcMaster element. They also differed in copy number, from just a few copies of Midi to few thousand copies of Krak. A modification of the DcMaster Transposon Display (DcMTD) marker system, targeted specifically towards Krak elements, was used to investigate their insertion polymorphism. It was shown that Krak insertion sites, similarly to those of the DcMaster elements, were highly polymorphic between the wild and the cultivated Daucus carota.

Here we describe the genetic and molecular characterization of 67 Ds insertion lines that show reduced transmission through the male gametophyte. About half of these mutations are male gametophytic-specific imitations, while the others also affect female transmission. Genomic sequences flanking both sides of the Ds element were recovered for 39 lines; for 16 the Ds elements were inserted in or close to coding regions, while 7 were located in intergenic/unannotated regions of the genome. For the remaining 16 lines, chromosomal rearrangements such as translocations or deletions, ranging between 30 and 500 kb, were associated with the transposition event. The mutants were classified into five groups according to the developmental processes affected; these ranged from defects in early stages of gametogenesis to later defects affecting pollen germination, Pollen tube growth, polarity or guidance, or pollen tube-embryo sac interactions or fertilization. The isolated mutants carry Ds insertions in genes with diverse biological functions and potentially specify new functions for several unannotated or unknown proteins.

Here, we explore the interaction of their maize homologs knotted1 (kn1) and thick tassel dwarf1 (td1). kn1 mutants form fewer lateral organs and td1 inflorescences are fasciated with additional floral organs. Double mutants show kn1 epistatic to td1 in seedling and ear development but dose-sensitivity exists later to promote leaf initiation. Thus kn1 and td1 function in a pathway to maintain meristem homeostasis but their products may interact with different partners during development. C1 [Hake, Sarah] USDA ARS, Albany, CA 94710 USA.

Recombination among these repetitive DNAs produces rearrangements affecting organization and expression of mitochondrial genes. To more efficiently identify rearrangements in the cucumber mitochondrial DNA, we built two nonoverlapping 800 and 220 kb BAC contigs and assigned major mitochondrial genes to these BACs. Polymorphism carried on the largest BAC contig was used to confirm paternal transmission. Mitochondrial genes were distributed across BACs and physically distant, although occasional clustering was observed. Introns in the nad1, nad4, and nad7 genes were larger than those reported in other plants, due in part to accumulation of short repetitive DNAs and indicating that increased intron sizes contributed to mitochondrial genome expansion in cucumber. Mitochondrial genes atp6 and atp9 are physically close to each other and cotranscribed. These physical contigs will be useful for eventual sequencing of the cucumber mitochondrial DNA, which can be exploited to more efficiently screen for unique rearrangements affecting mitochondrial gene expression.

Elymus L. is the largest and most complex genus in the Triticeae tribe with approximately 150 species occurring worldwide. The genomic constitutions of similar to 40% of Elymus species are unknown and some have unverified genomic combinations. Of those known for genome constitutions, Elymus species have a genomic formula of StH, StP, StY, StStY, StHY, StPY, or StWY. However, the origin of the Y genome is unknown because no diploid species have been identified as the Y genome donor. A putative Y genome specific random amplified polymorphic DNA (RAPD) marker was converted to a sequence tagged site (STS) marker. The reliability of this STS marker for confirming the presence of the Y genome was demonstrated using 42 accessions of Elymus. The STS-PCR for the Y genome marker was then assayed on 43 accessions of diploid Pseudoroegneria (Nevski) A. Love species having the St genome to identify possible donors of the Y genome. A rare accession of Pseudoroegneria spicata (Pursh) A. Love was found to possess sequences that most closely related to those from the tetraploid Elymus longearistatus (Boiss.) Tzvelev (StStYY), making P. spicata the most likely donor of the Y genome, although Pseudoroegneria libanotica (Heck.) D. R. Dewey or other Pseudoroegneria species could not be excluded. Our findings support the hypothesis that the Y genome in some Elymus species shares a progenitor genome (designated StY) with the St genome of Pseudoroegneria.

The objective of this study was to determine the physical location of the Rfo locus in the canola genome using fluorescence in situ hybridization and genetic mapping. For physical localization of the Rfo gene, two bacterial artificial chromosome (BAC) clones, G62 and B420, which were closely linked to the Rfo gene, were used as probes to hybridize with the somatic metaphase chromosomes of a canola hybrid variety, PHI-46 (46H02), containing the Rfo fragment. The results showed that both clones were physically located at the end of one large metacentric chromosome. By simultaneous use of two BAC clones and 45S rDNA repeated sequences as the probes, we demonstrated that the large metacentric chromosome probed with the two BAC clones did not carry 45S rDNA repeated sequences. The chromosome was 3.65 +/- 0.74 mu m in average length (20 cells) and ranked second in size among the chromosomes without 45S rDNAs. The centromere index of the chromosome (20 cells) was calculated as 43.74 +/- 4.19. A comparison with previously reported putative karyotypes of B. napus (AACC) and its diploid ancestors Brassica rapa L. (AA) and Brassica oleracea L. (CC) suggests that the chromosome carrying the Rfo fragment might belong to one of three large metacentric chromosomes of the C genome. Genetic mapping has confirmed the localization of the Rfo fragment to the distal region of linkage group N19, which corresponds to the C genome in B. napus. This study has provided the evidence of the location of the Rfo gene on canola chromosomes and established a basic framework for further physical mapping and manipulation of the gene.

Results suggest that there has been a significant increase in the number of publications per year since the first aeolian-research publication appeared in 1646. Rates of publication have increased from only three publications in the 17th Century to nearly three publications per day in the 21st Century. The temporal distribution of publications follows a complex pattern that is influenced by many factors. In the 17th and 18th Centuries, publications appear as isolated clusters indicating limited interest in aeolian research and limited opportunities for individuals to contribute to scientific literature. With time, many new scientific societies are formed and many new scientific journals are established, opening new opportunities for scientists to contribute to scientific discourse. Landmark publications open up new research areas and define new directions for aeolian research. General advances in science and technology provide new techniques for sampling blowing sand and dust. In addition, clear signs exist that publication rates respond to major environmental and climatic events, especially large-scale disasters that focus attention on wind erosion and blowing dust. The Sirocco dust events of 1901-1903, the North American Dust Bowl of the 1930s, and the recent sand and dust storm problems in China have all led to significant increases in the number of publications in aeolian research. Rates of publication are negatively influenced by major political and social upheavals, especially global conflicts such as World Wars I and II. Sudden shifts in government structure and support can also influence publication rates. A good example is the increased publication rates in China following the end of the Cultural Revolution, a trend that continues today. Published by Elsevier B.V.

By exposing the soil surface to the erosive action of winds, these disturbances contribute to the redistribution of soil nutrients associated with grassland-to-shrubland conversions and to the formation of a heterogeneous landscape. Wind erosion maintains the local heterogeneities in nutrient and vegetation distribution in and landscapes through the removal of nutrient-rich soil from the intercanopy areas and the subsequent deposition of soil onto vegetation patches. Even though wind erosion and disturbances like fires strongly interact with each other and determine vegetation patterns in and landscapes, very few studies have addressed these interactions. Using soil samples collected after a wildfire event at the Cimarron National Grasslands in southwestern Kansas, we demonstrate through a series of wind-tunnel experiments, laboratory measurements, and theoretical analyses how wind erosion can be enhanced by fire-induced water repellency. Results from the wind-tunnel experiments show that in semiarid grasslands fires can cause a decrease in the threshold velocity of wind erosion thereby, enhancing the post-bum erosion of (hydrophobic) soils. Further, a generalized process-based theoretical equation was derived to explain the decrease in threshold friction velocity in water-repellent soil for the case of soil particles modeled as asymmetrical cones.

TI Effects of Sampling Interval on Spatial Patterns and Statistics of Watershed Nitrogen Concentration SO GISCIENCE & REMOTE SENSING LA English DT Article ID POLLUTION MODEL; ACCURACY; OPTIMIZATION; VARIABILITY; BIOMASS; DENSITY; AGNPS; SOILS AB This study investigates how spatial patterns and statistics of a 30 m resolution, model-simulated, watershed nitrogen concentration surface change with sampling intervals from 30 m to 600 m for every 30 m increase for the Little River Watershed (Georgia, USA). The results indicate that the mean, standard deviation, and variogram sills do not have consistent trends with increasing sampling intervals, whereas the variogram ranges remain constant. A sampling interval smaller than or equal to 90 m is necessary to build a representative variogram. The interpolation accuracy, clustering level, and total hot spot areas show decreasing trends approximating a logarithmic function. The trends correspond to the nitrogen variogram and start to level at a sampling interval of 360 m, which is therefore regarded as a critical spatial scale of the Little River Watershed.

Nevertheless, there is reason to believe that interactions among above- and belowground communities may mediate ecosystem responses to global change. We used grassland mesocosms to manipulate the abundance of one important group of soil organisms, arbuscular mycorrhizal (AM) fungi, and to study community and ecosystem responses to CO(2) and N enrichment. Responses of plants, AM fungi, phospholipid fatty acids and community-level physiological profiles were measured after two growing seasons. Ecosystem responses were examined by measuring net primary production (NPP), evapotranspiration, total soil organic matter (SOM), and extractable mineral N. Structural equation modeling was used to examine the causal relationships among treatments and response variables. We found that while CO(2) and N tended to directly impact ecosystem functions (evapotranspiration and NPP, respectively), AM fungi indirectly impacted ecosystem functions by influencing the community composition of plants and other root fungi, soil fungi and soil bacteria. We found that the mycotrophic status of the dominant plant species in the mesocosms determined whether the presence of AM fungi increased or decreased NPP. Mycotrophic grasses dominated the mesocosm communities during the first growing season, and the mycorrhizal treatments had the highest NPP. In contrast, nonmycotrophic forbs were dominant during the second growing season and the mycorrhizal treatments had the lowest NPP. The composition of the plant community strongly influenced soil N, and the community composition of soil organisms strongly influenced SOM accumulation in the mesocosms. These results show how linkages between above- and belowground communities can determine ecosystem responses to global change.

We recorded 158 captures of 13 species of snakes from 12 study sites. We captured more snakes in funnel traps than in pitfalls. The most frequent captures were Common Kingsnakes (Lampropeltis getula), Gopher Snakes (Pituophis catenifer), Plains Black-headed Snakes (Tantilla nigriceps), and Plains Hog-nosed Snakes (Heterodon nasicus). We did not detect an effect of non-native plants and fuels removal on the rate of captures; however, we recommend using other trapping and survey techniques to monitor snakes to better determine the impact of plant removal on the snake community. Compared to historical records, we did not report any new species but we did not capture all snakes previously recorded. Black-necked Gartersnakes (Thamnophis cyrtopsis), which are closely tied to aquatic habitats, were not captured during our study; possibly indicating the loss of off-channel semi-aquatic habitats along the Middle Rio Grande.

TI Sources of Resistance in US Plant Introductions to Watermelon Vine Decline Caused by Squash Vein Yellowing Virus SO HORTSCIENCE LA English DT Article DE Bemisia tabaci; Potyvirus; Cucurbit; Ipomovirus; host plant resistance ID CITRULLUS-COLOCYNTHIS; POTENTIAL SOURCES; MOSAIC-VIRUS; GERM PLASM; GERMPLASM; LANATUS; FLORIDA AB Watermelon vine decline (WVD) is a new and emerging disease caused by the whitefly-transmitted squash vein yellowing virus (SqVYV). The disease has become a major limiting factor in watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] production in southwest and west-central Florida and is estimated to have caused more than $60 million in losses. Symptoms of WVD typically occur at or just before harvest and are manifested as sudden decline of the vines, often with a reduction in fruit quality. In this study, we present results of greenhouse and field evaluations of U.S. plant introductions (Pis) for resistance to SqVYV. Of the 218 Pis we evaluated for resistance to SqVYV, none were completely immune, but several showed varying levels of resistance and these were further evaluated in two greenhouse and field trials. Disease progress was significantly slower on the selected Pis compared with disease progress on susceptible watermelon cultivars Mickey Lee and Crimson Sweet. Moderate resistance was observed in two C. colocynthis (PI 386015 and PI 386024), a Praecitrullus fistulosus (PI 3817419), and two C lanatus var. lanatus Pis (PI 482266 and PI 392291). Variability in the resistant reaction to SqVYV within most Pis was observed. The identification of potential sources of partial resistance to SqVYV suggests that watermelon germplasm with moderate resistance can be developed by careful screening and selection of individual resistant plants within these Pis for use in breeding programs.

Dawson (Xcc), is a serious disease of vegetable crucifers worldwide. The USDA NC-7 and NE-9 regional PI stations maintain vegetable, mustard, and oilseed crucifers, of which 4084 accessions were available for testing, representing 23 genera and 125 species. These accessions were evaluated for resistance to black rot after wound inoculation with race I of the pathogen. Accessions that were symptomless for race 1 of Xcc were replanted and inoculated with race 4 of the pathogen to identify accessions with resistance to both races. Symptomless responses were observed in 362 accessions of the mustard species (Brassica juncea, Brassica carinata, and Brassica nigra), in particular, B. juncea for which 353 of the 389 accessions tested were symptomless. Resistance was identified in five accessions of B. carinata out of 63 evaluated (PI 193460, PI 193959, PI 194254, PI 280230, PI 633077) determined by repeated symptomless responses after inoculation and four accessions of B. nigra from the 83 evaluated (PI 197401, A 25399, A 25401, PI 458981). Five accessions of Brassica rapa (PI 633154, A9285, PI 340208, PI 597831, PI 173847) were identified, which represent promising new sources of resistance to Xcc. Incomplete resistance was identified in an accession of Eruca sativa (PI 633207), an accession of Lepidium spp. (PI 633265), an accession of Sinapis arvensis (PI 296079), and two accessions of B. napus (PI 469733 and PI 469828). These identified accessions represent germplasm that can be used in breeding for resistance to Xcc in vegetable crucifers through interspecific crossing.

TI A Comparison of Three Cold-climate Strawberry Production Systems: Environmental Effects SO HORTSCIENCE LA English DT Article DE advanced matted row; Fragaria Xananassa; erosion; pesticide; plastic mulch; nitrogen uptake; nitrogen use efficiency ID RUNOFF; TRANSPORT; GENOTYPES; ATRAZINE; PLANTS AB The environmental effects of the three strawberry (Fragaria Xananassa) cold-climate production systems were compared: the traditional method of conventional matted row (CMR) and the two more recently developed practices of advanced matted row (AMR) and cold-climate plasticulture (CCP). Side-by-side field plots were instrumented with automated How meters and samplers to measure and collect runoff, which was filtered and analyzed to determine soil, pesticide, and nitrogen losses. Although annual mean runoff volumes were similar for all three production systems, the soil losses from CMR plots were two to three times greater than the CCP plots throughout the study and two to three times greater than the AMR plots only in the first year of the 3-year study. In general, decreases in erosion and runoff volumes were observed in plots that were disturbed less by machine operations and had less foot traffic as a result of decreased need for hand weeding and in the plots that used straw mulch in the furrows between the beds. Timing and intensity of precipitation events also influenced the amount of soil erosion. Pesticide residues and nitrogen losses were also greatest in the runoff from the CMR plots. The two systems that used drip fertigation, AMR and CCP, also had higher nitrogen uptake efficiencies. Overall, the CCP and AMR systems performed similarly for most criteria; however, considering the nonrenewable nature of the plastic mulch and the need to dispose of the plastic mulch in a landfill, the AMR system was more environmentally sustainable than the CCP system.

K. Koch] trees native to northern regions are more cold-tolerant than those native to and grown in the southern United States. To identify a possible assay for cold hardiness, dormant winter twigs from 112 diverse pecan cultivars grown in Texas were surveyed using differential thermal analyses (DTA). The low temperature exotherm (LTE) from DTA was identifiable when twigs were stored at 3 degrees C for up to 120 d after harvest. Thirty-nine percent of the southern pecan cultivars lacked an obvious LTE, and the remaining southern cultivars had an average LTE of 32.9 degrees C. In contrast, only 11% of the northern pecan cultivars lacked the LTE and the remaining cultivars had a significantly lower LTE of -35.4 degrees C. Because twig samples were collected from trees grown in the same Texas orchard, it is suggested that there is a genetic component that affects the temperature of the LTE. Budbreak generally occurred earlier in southern cultivars than those that originated in the north. Both budbreak and LTE data can be correlated with regional origin; timing of budbreak may be preferred over DTA to predict relative cold hardiness in pecan.

In grapevines (Vitis labruscana Bailey), measurements of shoot and fruit fresh mass were collected at frequent intervals (14 to 21 days) over 5 years, and these data were correlated with variables that could be obtained nondestructively: shoot length, number of leaves per shoot, and number of clusters per shoot. Shoot length provided a good estimator of shoot fresh mass in all years. Nonlinear logistic regression models described the dynamics of canopy growth from bloom to the early stages of ripening, which often is poorly represented by simple linear regression approaches to seasonal data. A generalized function indicated a lower bound of approximate to 600 degree-days, after which an increase in shoot fresh mass could be considered on average to contribute only slightly to further increases in trellis wire tension. The dynamics of fruit mass were captured adequately by a nonlinear function, but not as well as vegetative mass because of larger variances in fruit mass. The number of clusters per shoot was associated with fruit mass only after the accumulation of approximate to 550 degree-days or, equivalently, the time at which fruit mass exceeded approximate to 25 g per shoot. Seasonal dynamics of the ratio of fruit to vegetative fresh mass were not sufficiently discernable by the logistic models because of the dominance of fruit mass and its large interannual variation.

Twenty-five commercial sweet corn hybrids from nine seed companies were grown in the presence and absence of wild-proso Millet (Panicum miliaceum L.) to 1) quantify tolerance in crop growth and yield to weed interference; 2) determine associations between tolerance in crop growth and yield; and 3) identify hybrids differing in tolerance to weed interference. Despite large differences in canopy architecture among hybrids, crop height and leaf uprightness were minimally affected by weed interference. in contrast, wild-proso millet interference reduced ear number 11% to 98% and ear mass 24% to 82% depending on the hybrid. The ability of a hybrid to make small growth adjustments in the presence of wild-proso millet appeared to have no relationship to yield tolerance. The least competitive hybrids were 'ACX1413', 'Optimum', 'Quickie', 'Spring Treat', and 'Sugar Buns'. The most competitive hybrids were 'Code128', 'Coho','El Toro', 'EX 8716622', and 'Legacy'. Although some exceptions were observed, in general, the longer-maturity processing hybrids were more competitive with wild-proso millet than the earlier-maturing fresh market hybrids.

TI Crop Coefficients Specific to Multiple Phenological Stages for Evapotranspiration-based Irrigation Management of Onion and Spinach SO HORTSCIENCE LA English DT Article DE ET measurement; weighing lysimeter ID WEIGHING LYSIMETERS; COTTON; MODEL AB Weighing lysimeters are used to measure crop water use during the growing season. By relating the water use of a specific crop to a well-watered reference crop such as grass, crop coefficients (KC) can be developed to assist in predicting crop needs using meteorological data available from weather stations. This research was conducted to determine growth stage-specific K(C) and crop water use for onions (Allium cepa L.) and spinach (Spinacia oleracea L.) grown under south Texas conditions. Seven lysimeters, consisting of undisturbed 1.5 x 2.0 x 2.2-m deep soil monoliths, comprise the Texas AgriLife Research-Uvalde lysimeter facility. Six lysimeters, weighing approximate to 14 Mg, have been placed each in the middle of a I-ha field beneath a linear low-energy precision application irrigation system. A seventh lysimeter was established to measure reference grass reference evapotranspiration. Daily water use for onion and spinach was measured at 5-min intervals. Crop water requirements, KC determination, and comparison with existing Food and Agricultural Organization (FAO) K(C) values were determined over a 2-year period for each crop. The K(C)-values determined over the growing seasons varied from 0.2 to 1.3 for onion and 0.2 to 1.5 for spinach with some of the values in agreement with those from FAO. It is assumed that the application of growth stage-specific KC will assist in irrigation management and provide precise water applications for a region of interest.

TI Inoculating Acacia koa with Bradyrhizobium and Applying Fertilizer in the Nursery: Effects on Nodule Formation and Seedling Growth SO HORTSCIENCE LA English DT Article DE container nursery; controlled-release fertilizer; nitrogen use efficiency; nitrogen-fixing bacteria; forest restoration ID SHRUB RETAMA-SPHAEROCARPA; RHIZOBIUM SYMBIOSIS; NATIVE RHIZOBIA; WATER-STRESS; HAWAII; LEGUMES; FORESTS; ESTABLISHMENT; REVEGETATION; RESTORATION AB Restoration of Acacia koa A. Gray (koa) forests on degraded sites in Hawaii is important for conservation of rare, endemic plants and animals and is often accomplished by planting nursery-grown seedlings. To be successful after outplanting, koa seedlings must access sufficient nutrients from the soil and outcompete other vegetation. Forming symbiotic associations with nitrogen-fixing microorganisms may help alleviate inherent nutrient deficiencies found on volcanic sites, but interactions between inoculation and fertilization during production of koa seedlings are not well studied. Under operational nursery conditions, we fertilized koa seedlings at six controlled-release fertilizer (CRF) rates (ranging from 0 to 11.9 kg.m(-3) Osmocote Plus 15N-9P-12K), which were also either inoculated with a locally collected source of nitrogen-fixing Bradyrhizobium spp. or not. Fertilized seedlings were significantly larger than the control; on average, fertilized seedlings were 300% taller and had 180%, 700%, and 350% more root-collar diameter, shoot biomass, and root biomass, respectively. Nitrogen (N) concentration was 23% to 119% greater in fertilized seedlings than nonfertilized seedlings. Inoculation with Bradyrhizobium had no significant affect on seedling characteristics except for root N concentration, which was 8% higher for inoculated seedlings. Fertilizer rate and inoculation interacted to significantly affect nodule number and nodule biomass/seedling. With inoculation, we observed an increase in nodule number (16.5 to 25.5) and biomass (5.8 mg to 11.7 mg) with fertilizer rate tip to 4.7 kg.m(-3) but a decline to nearly zero at the highest rates. Without inoculation, nodule formation was scarce (3.2 nodules/seedling or less) and only observed when CRF was 2.3 kg.m(-3) or less. Our results suggest that high rates of fertilization and successful nodulation are not mutually exclusive nursery practices. Concurrent use of fertilization and inoculation in the nursery may provide opportunity to produce larger seedlings that have high potential to reduce the time needed to achieve canopy closure and thereby help achieve restoration objectives.

Understanding flurprimidol release from a granular formulation and movement in various mediums will impact how it is used. Dissipation of flurprimidol from a granular formulation and movement through organic media and sand were evaluated in a greenhouse and laboratory experiment. Experimental variables included media type, depth, and irrigation event. Dissipation isotherms were determined by applying nonlinear regression. Mobility was evaluated using columns filled with media, which was surface-spiked with the granular formulation and then irrigated once daily for 22 consecutive days. Leachate was collected and analyzed by high-performance liquid chromatography mass spectroscopy. Half-life (DT(50)), defined as time to 50% reduction, varied among sand, media, and media depth. Flurprimidol dissipation was rapid through sand with DT(50) of 6 days. DT(50) increased with increasing media depth from 5 to 10 cm for pine bark plus sand, 18 and 35 days, and hardwood bark plus sand, 77 and 173 days, respectively. Maximum flurprimidol leaching was a cumulative 71% of applied amounts over 22 irrigation events through the sand. Hardwood and pine bark media allowed less than 25% of flurprimidol to escape through the column. Data for all media indicated that flurprimidol was mobile through the substrates but exhibited hysteresis with pine bark and hard wood bark media. An initial pulse of flurprimidol will release slowly from this formulation over time. These results indicate that flurprimidol will dissipate from a granular formulation over time and that it will have movement through sand soil and pine bark and hardwood bark media to reach the roots of growing plants.

California regulations require that nursery stock for farm planting be commercially clean with respect to economically important nematodes. Under the terms of the Montreal Protocol, the use of methyl bromide by developed countries was phased out 1 Jan. 2005. Although the perennial nursery industry in the United States largely continues to use methyl bromide under critical use exemptions and quarantine/preshipment criteria allowed under provisions of the Montreal Protocol, nursery growers need viable alternatives to this fumigant. Two fumigation trials in perennial crop field nurseries with sandy loam and clay loam soils, respectively, were conducted to compare the efficacy of fumigants applied through standard shank-injection equipment or as emulsifiable compounds applied through drip irrigation equipment. In the garden rose (Rosa multi flora) nursery trial, nematodes were detected at planting in the untreated control, no-tarpaulin 1,3-dichloropropene + chloropicrin, and chloropicrin alone several months after treatment. Nematodes included root-knot nematode (Meloidogyne spp.) and stunt nematode (Tylenchorhynchus semipenetrans). At harvest 2 years later, root-knot nematode was detected in rose roots from untreated plots and plots treated with untarped 1,3-dichloropropene + chloropicrin, metam sodium, and chloropicrin alone. In the nut tree (Prunus spp.) nursery field trial, shank-injected treatments typically provided better nematode control than the same chemicals applied via the drip lines, although weed control and marketable trees were similar among treatments.

Our objective was to determine the effect of time of sweetpotato whitefly infestation on plant nutrition and the development of TIR disorder. Healthy tomato plants (Solanum lycopersicum 'Florida Lanai') were introduced to sweetpotato whitefly infestations at different developmental stages of plant growth: 1) five to seven true leaves, 2) flower, 3) green fruit, and 4) breaking red fruit and were compared with noninfested control plants of the same age. Plants were fertilized every 7 to 14 days. Plant nutrition was monitored over time between the noninfested control and the longest infestation interval (five to seven true leaves) and between all infestation intervals at harvest. Sweetpotato whitefly (egg, nymph, and adult) and plant parameters (height, canopy diameter, number of leaves, flowers, and fruit per plant) were taken every 7 to 14 days after sweetpotato whitefly infestation. Almost all of the fruit (99%) produced by tomato plants infested with sweetpotato whitefly at stages 1 and 2 (78 and 56 days of sweetpotato whitefly exposure, respectively) developed TIR with fruit exhibiting internal and external symptoms. Plants infested at stage 3 (35 days of sweetpotato whitefly exposure) had 79% to 80% of the fruit develop TIR. Surprisingly, 58% of fruit from plants infested at stage 4 (14 days of sweetpotato whitefly exposure) also developed the disorder, indicating that tomatoes may need to be protected from sweetpotato whitefly until harvest to avoid this disorder. Seed germination was unaffected by TIR. Plants infested with sweetpotato whitefly had mean foliar levels of calcium, copper, iron, phosphorous, potassium, magnesium, manganese, and zinc that were greater than in noninfested control plants at final harvest for both studies, regardless of time of infestation.

Navel oranges were harvested after the freeze from 14 sites that were previously determined to have a slight to moderate amount of freeze damage. The fruit were evaluated for the presence of small yellow spots characteristic of freeze damage that fluoresce when viewed under a ultraviolet-A (365 nm) source and were then cut and rated using a method currently used by the California Department of Food and Agriculture (CDFA) to determine the presence of internal freeze damage. The percentage of freeze-damaged fruit in each lot as determined by the CDFA method ranged from 0% to 89%. The accuracy of classifying fruit as freeze damaged in each lot by peel fluorescence averaged 44%, with the fruit lots containing the greatest amount of freeze damage having the highest classification percentages. False-positives occurred at a lower rate than false-negatives among the lots. Although some fading was evident, the fluorescence persisted and was readily visible for at least 9 weeks after the freeze event. Removal of fruit with ultraviolet peel fluorescence was ineffective in reducing the percentage of damaged fruit within the examined lots. In the second part of the test, eighteen lots of potentially freeze-damaged fruit were obtained from a packing house, immediately evaluated for freeze damage using ultraviolet light, and then after 4 weeks of storage, were evaluated again using the CDFA method. Fruit that had a slight to moderate degree of freeze damage were tasted and evaluated for sensory characteristics. Both methods of freeze damage detection were poorly related to the sensory characteristics. C1 [Obenland, David; Margosan, Dennis] ARS, USDA, Parlier, CA 93648 USA.

The field has grown to the extent that now over 500 insect cell lines have been established from many insect species representing numerous insect orders and from several different tissue sources. These cell lines are used as research tools in virology, in studies of signaling mechanisms to study insect immunity, hemocyte migration, and to test hypotheses about gene expression, and in screening programs designed to discover new insecticide chemistries. Virology research is revealing fundamentally new information on virus/host cell interactions. Studies in gene expression are uncovering signal transduction pathways that are new to insect science. Research is leading to the development of high-speed screening technologies that are essential in the search for new insect pest management tools. A few insect cell lines are, in routine industrial processes, designed to produce proteins of biomedical significance. Both primary cell cultures and established lines are used in basic biological studies to reveal how insect cells work. This review is designed to briefly cover the history of insect cell culture, recount some recent advances in the field, and offer a vision of the future of insect cell culture.

Adventitious buds were induced directly from Agrobacterium-infected leaf bases and stem discs of in vitro plants, bypassing the establishment of callus cultures. Non-chimeric transgenic plants were obtained by multiple subculturing of primary transformants under increasing levels of selection. A total of 42 independent transgenic lines were produced from two cultivars with two different constructs: one containing a modified rice cystatin gene (Oc-I Delta D86) and the other with the anti-sense gene to pineapple aminocyclopropane synthase (ACS). GUS histochemical staining provided the first evidence of the non-chimeric nature of the transformed plants. Their non-chimeric nature was further demonstrated by PCR analyses of the DNA extracted from individual leaves of a primary transformed plant and also from multiple plants propagated from a single transformation event. Southern hybridization confirmed random integration patterns of transgenes in the independent lines. For the Oc-I Delta D86 gene, the expression at the mRNA level was detected via RT-PCR and its translation was detected by protein blot. Agronomic evaluation and bioassays of the transgenic plants will further validate the utility of this new tool for pineapple improvement. C1 [Uruu, G.; Cheah, K. T.; Paull, R.

TI Independence of Anaplasma marginale Strains with High and Low Transmission Efficiencies in the Tick Vector following Simultaneous Acquisition by Feeding on a Superinfected Mammalian Reservoir Host SO INFECTION AND IMMUNITY LA English DT Article ID DERMACENTOR-ANDERSONI ACARI; AMERICAN DOG TICK; ANTIGENIC VARIATION; BORNE TRANSMISSION; SALIVARY-GLANDS; RICKETTSIALES; IXODIDAE; VARIABILIS; SURFACE; POPULATIONS AB Strain superinfection occurs when a second pathogen strain infects a host already carrying a primary strain. Anaplasma marginale superinfection occurs when the second strain carries a variant repertoire different from that of the primary strain, and the epidemiologic consequences depend on the relative efficiencies of tick-borne transmission of the two strains. Following strain superinfection in the reservoir host, we tested whether the presence of two A. marginale (sensu lato) strains that differed in transmission efficiency altered the transmission phenotypes in comparison to those for single-strain infections. Dermacentor andersoni ticks were fed on animals superinfected with the Anaplasma marginale subsp. centrale vaccine strain (low transmission efficiency) and the A. marginale St. Maries strain (high transmission efficiency). Within ticks that acquired both strains, the St. Maries strain had a competitive advantage and replicated to significantly higher levels than the vaccine strain. The St. Maries strain was subsequently transmitted to naive hosts by ticks previously fed either on superinfected animals or on animals singly infected with the St. Maries strain, consistent with the predicted transmission phenotype of this strain and the lack of interference due to the presence of a competing low-efficiency strain. The vaccine strain was not transmitted by either singly infected or coinfected ticks, consistent with the predicted transmission phenotype and the lack of enhancement due to the presence of a high-efficiency strain. These results support the idea that the strain predominance in regions of endemicity is mediated by the intrinsic transmission efficiency of specific strains regardless of occurrence of superinfection.

Strain 43895OR produces an abundant extracellular matrix rich in curli fibers, forms biofilms on solid surfaces, invades cultured epithelial cells, and is more virulent in mice than strain 43895. In this study we compared the formic acid-soluble proteins expressed by strains 43895OR and 43895 using one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis and identified two differentially expressed proteins. A 17-kDa protein unique to strain 43895OR was identified from matrix-assisted laser desorption ionization-time of flight analysis combined with mass spectrometry (MS) and tandem MS (MS/MS) as the curli subunit encoded by csgA. A < 10-kDa protein, more highly expressed in strain 43895, was identified as the Lpp lipoprotein. Mutants of strain 43895OR with disruption of lpp, csgA, or both lpp and csgA were created and tested for changes in phenotype and function. The results of this study show that both Lpp and CsgA contribute to the observed colony morphology, Congo red binding, motility, and biofilm formation. We also show that both CsgA and Lpp are required by strain 43895OR for the invasion of cultured HEp-2 cells. These studies suggest that in strain 43895OR, the murein lipoprotein Lpp indirectly regulates CsgA expression through the CpxAR system by a posttranscriptional mechanism.

Nine pure-bred Angus castrated males (i.e. steers; average body weight 299 +/- 5 kg) were used in a randomized complete block design in environmentally controlled chambers, set at thermoneutral level, to characterize the acute physiological, endocrine, immune, and acute-phase protein responses following an i.v. bolus administration of 2.5 mg of LPS/kg body weight. One day before administration of LPS, all steers were fitted with an indwelling jugular vein catheter for serial blood collection. Blood samples were collected at 30-min intervals from -2h to 8 h relative to the LPS challenge ( time 0), and serum was harvested and stored at -80 degrees C until analyzed for concentrations of cortisol, pro-inflammatory cytokines, and acute-phase proteins. Indicators of thermal status (i.e. rectal temperature, ruminal temperature, respiration rate, sweat rate, and skin temperatures) were measured at 30-min intervals from -1 h to 6 h relative to the challenge. Endotoxin exposure increased (P < 0.05) serum concentrations of cortisol, tumor necrosis factor-alpha (TNF-alpha), interleukin 1-b (IL-1b), IL-6, interferon-gamma (IFN-gamma), and serum amyloid A. Respiration rate, rectal temperature, and rump skin temperature also were increased (P < 0.05) following LPS administration. Endotoxin exposure dramatically decreased ear skin temperature (P = 0.002), but tended to increase (P < 0.10) ruminal temperature, shoulder skin temperature, and shoulder sweat rate. Serum concentrations of acid soluble protein, a-acid glycoprotein, IL-4 and IL-2, and rump sweat rate were not altered (P > 0.24) by the challenge. To our knowledge, this report is the most complete characterization of the bovine acute-phase response to a bolus-dose endotoxin challenge conducted under thermoneutral conditions and should provide foundation data for future research.

Such models have been shown to be inadequate in predicting growth of the organisms under dynamic conditions commonly encountered in the food industry. The object of the current research was to develop a predictive model for Clostridium perfringens spore germination and outgrowth in cooked chicken products during cooling by incorporating a function to describe the prior history of the microbial cell in the secondary model. Incorporating an assumption that growth kinetics depends in an explicit way on the cells' history could provide accurate estimates of growth or inactivation. Cooked, ground uncured chicken was inoculated with C. perfringens spores. and from this chicken, samples were formed and vacuum packaged. For the isothermal experiments, all samples were incubated in a constant temperature water baths stabilized at selected temperatures between 10 and 51 degrees C and sampled periodically. The samples were cooled from 54.4 to 27 degrees C and subsequently from 27 to 4 degrees C at different time periods (cooling rates) for dynamic cooling experiments. The standard model provided predictions that varied from the observed mean logo growth values by magnitudes up to about 0.65 log(10). However, for a selected memory model, estimates of log,a relative growth provided predictions within 0.3 log(10) of the mean observed logo growth values. These findings point to an improvement of predictions obtained by memory models over those obtained by the standard model. More study though is needed to validate the selected model.

We previously reported the identification of HvALP in the midgut of Heliothis virescens larvae as a Cry1Ac-binding protein that is down-regulated in Cry1Ac-resistant insects. To further characterize HvALP, we localized mALP protein to foregut and midgut tissues using anti-mALP serum and then cloned five mALPs from H. virescens larval midgut. All five clones displayed high levels of sequence identity (above 90%), suggesting that they may represent allelic variants, and grouped with other lepidopteran mALPs in sequence alignments. All these cloned ALPs were predicted to contain a glycosylphosphatidylinositol (GPI) anchor and were named HvmALP1-5. We expressed two of the most diverse HvmALPs in a heterologous system to test binding of Cry1Ac and recognition by HvALP cross-reacting antiserum. Our data highlight the importance of glycosylation for Cry1Ac binding to HvALP and suggest that, depending on glycosylation, all the identified HvmALPs may be synonymous with HvALP, the Cry1Ac-binding phosphatase identified in H. virescens midgut epithelium.

Vander TI Identification of a new member of the PBAN family of neuropeptides from the fire ant, Solenopsis invicta SO INSECT MOLECULAR BIOLOGY LA English DT Article DE Fire ant; PBAN; Neuropeptide; Pheromone; Solenopsis invicta ID BIOSYNTHESIS-ACTIVATING NEUROPEPTIDE; SEX-PHEROMONE PRODUCTION; CENTRAL-NERVOUS-SYSTEM; AMINO-ACID-SEQUENCE; GENE-ENCODING DH; DIAPAUSE HORMONE; HELICOVERPA-ZEA; BOMBYX-MORI; SUBESOPHAGEAL GANGLION; MOLECULAR CHARACTERIZATION AB Neuropeptide hormones produced by neurosecretory cells in the central or peripheral nervous systems regulate various physiological and behavioral events during insect development and reproduction. PBAN/Pyrokinin is a major neuropeptide family, characterized by a 5-amino-acid C-terminal sequence, FXPRLamide. This family of peptides has been implicated in regulating various physiological functions including, pheromone biosynthesis, muscle contraction, diapause induction or termination, melanization, and puparium formation in different insect species. In the present study, we report a new member of the PBAN family from the red imported fire ant, Solenopsis invicta, Soi-PBAN, composed of 26-AA (GSGEDLSYGDAYEVDEDDHPLFVPRL). Three additional peptides were deduced from Soi-PBAN cDNA: 15-AA (TSQDIASGMWFGPRL), 8-AA (QPQFTPRL) and 9-AA (LPWIPSPRL), that correspond to diapause hormone (DH), beta-neuropeptide (NP), and gamma-NP, which are found in many lepidopteran moths. Five peptides, DH, alpha, beta, gamma NPs, and PBAN are encoded from PBAN genes of lepidopteran moths, but in the fire ant the alpha-NP is missing. Each of the four synthetic peptides from the fire ant Soi-PBAN cDNA showed significant pheromonotropic activity in a moth model, indicating that these peptides are cross-reactive. Soi-beta-NP induced the highest amount of pheromone production of the four peptides evaluated. The Soi-DH homologue had the lowest pheromonotropic activity, but was still significantly greater than control values. When the deduced amino acid sequences (entire ORF domains) from Soi-PBAN cDNA were compared with other known sequences, the fire ant was most similar to the honey bee, but phylogenetically distant from moth and beetle species. Soi-PBAN (26-AA) unlike the other three peptides shows a low degree of sequence identity with honeybee PBAN (33-AA). Based on the amino acid sequences encoded from insect PBAN genes identified to date, neuropeptide diversity is correlated with the taxonomic or phylogenetic classification of Insecta. From the present study we report the first neuropeptide identified and characterized from the central nervous system of Formicidae. C1 [Choi, M. -Y.; Meer, R. K.

Survival was assessed when the beetles were removed from the exposure arenas and daily during the post-exposure period. In the presence of food, survival was high regardless of concentration and the day on which post-treatment survival was assessed, but survival did decrease as the exposure period increased from 4 to 8 h. When the beetles were not given food after exposure, survival at each concentration and exposure period declined during the 1-week post-exposure assessments. This pattern of decrease could be described by linear and non-linear equations. Results show the presence of food material greatly compromised effectiveness of the insecticide, and emphasize the importance of cleaning and sanitation in conjunction with insecticide treatments.

Changes of resistance to pyrethroid insecticide associated with use of a pour-on formulation of cyfluthrin in 2002 and use of diazinon ear tags in subsequent years were studied using a filter paper bioassay technique and a polymerase chain reaction assay that detects two sodium channel mutations, kdr and super-kdr resistance alleles. A maximum of 294-fold resistance to permethrin was observed in the summer of 2002. A significant decrease in the resistance level was observed in spring 2003, and resistance continued to decline after animals were treated with diazinon ear tags. In response to pyrethroid treatments, the allelic kdr and super-kdr frequency increased from 56.3% to 93.8% and from 7.5% to 43.8%, respectively in 2002, and decreased significantly in 2003 when the pyrethroid insecticide was no longer used to treat animals. Females were found to have a higher allelic super-kdr frequency than males in 2002, while no difference was detected between males and females in the allelic kdr frequency. There was a significant positive correlation between frequencies of the sodium channel mutations and levels of permethrin resistance, suggesting that the sodium channel mutations, kdr and super-kdr, are the major mechanisms of resistance to pyrethroids in this horn fly population. Results of synergist bioassays also indicated possible contributions of two metabolic detoxification mechanisms, the mixed function oxidases (MFO) and glutathione S-transferases (GST). Compared to a horn fly infestation of an untreated herd, treatments with the pyrethroid pour-on formulation failed to control horn flies at the Pressler ranch in 2002. Sustained control of horn flies was achieved with the use of diazinon ear tags in 2003 and subsequent years. C1 [Li, Andrew Y.; Lohmeyer, Kimberly H.; Miller, J.

Fuji applesauce and blueberry applesauce were processed with PEF followed by HTST pasteurisation (PEF + HTST). PEF + HTST processed Fuji applesauce from fresh Fuji apples demonstrated high and stable sensory scores during 9 months storage at 27 degrees C, and had comparative sensory quality with Meal Read-to-Eat (MRE) and commercial applesauce products stored at 4 degrees C. PEF + HTST processed blueberry applesauce from pre-pasteurised materials had lower sensory scores than PEF + HTST processed Fuji applesauce and was significantly less stable during the storage at 27 degrees C. PEF + HTST processed applesauces had aerobic count and mould and yeast count of < 10 cfu mL(-1) during storage.

TI Variable Impacts of Imazapic Rate on Downy Brome (Bromus tectorum) and Seeded Species in Two Rangeland Communities SO INVASIVE PLANT SCIENCE AND MANAGEMENT LA English DT Article DE Assisted succession; integrated weed management; rangeland seeding; seedling establishment AB The herbicide imazapic is registered for use on rangelands and provides effective short-term control of certain invasive annual grasses. However, details about optimal application rates for downy brome and susceptibility of simultaneously seeded species are lacking. Thus, we investigated downy brome and seeded species responses to variable rates of imazapic (0, 35, 70, 105, and 140 g ai/ha) in two plant communities (salt desert shrub and Wyoming big sagebrush). In autumn 2003, plots were treated with imazapic and seeded with one of five perennial plant materials (Siberian wheatgrass ['Vavilov' and the experimental source Kazak]; prostrate kochia ['Immigrant' and the experimental source 6X], and Russian wildrye ['Bozoisky II']). Downy brome cover and seeded species establishment were evaluated in spring 2004 and 2006. Downy brome cover in 2004 decreased with increasing imazapic rate at both sites, although more so at the Wyoming big sagebrush site. In 2006, no difference in downy brome cover existed among herbicide rates at the Wyoming big sagebrush site. At the salt desert shrub site, the high rate of imazapic reduced downy brome cover by about 25% compared to untreated plots. 'Vavilov' Siberian wheatgrass was the only seeded species with lower downy brome cover in 2006 than 2004. Seeded species establishment increased with imazapic rate in the salt desert shrub community, but in the Wyoming big sagebrush community it peaked at intermediate rates and declined at higher rates. Variation in downy brome control and seeded species establishment might have been associated with differences in precipitation, soil organic matter, and disturbance history between sites. Overall, imazapic was useful for helping establish desirable perennial species, but unless downy brome is reduced below a critical threshold, favorable precipitation can return sites to pretreatment levels within two years.

Our objective was to determine the influence of litter from an intact native plant community on a community dominated by an invasive species within the same habitat type as well as the influence of litter from a community dominated by an invasive species on an intact native plant community. We hypothesized that litter amount, type (source), and fragment size would influence various functional groups within a native plant community differently than within a weed-dominated plant community. We used reciprocal plant litter exchanges between native and invasive plant-dominated grasslands to gain an initial understanding of litter's influence on the density and biomass of native grasses, native forbs, common St. Johnswort, and downy brome. Common St. Johnswort was not influenced by any treatment. Native grass density increased with application of low (454 g/m(2)) amounts of litter where the grasses were subordinate to common St. Johnswort, and adding native plant litter to the weedy site nearly doubled native grass biomass. Low amounts of finely fragmented litter and high amounts of coarse litter induced native forbs to produce about twice the biomass as found in the non-litter-amended controls. Our study suggests that plant litter may be a component of vegetation that can be managed to shift the plant community toward those plants that are desired.

In this article, recommendations are given for constructing a rain screen, sealing the end grain, and back-priming siding to achieve this goal. Rain screen construction and back priming inhibit water absorption and bleed front run-down extractives if water gets behind the siding. Inhibiting water absorption improves dimensional stability of siding, thus improving finish performance. Sealing the end grain with primer decreases paint peeling and bleeding of diffuse extractives near the end of boards. These techniques should overhangs, ground should be used in combination with structure designs having adequate roof once to bottom course of siding, roof-edge flashing, gutters, and downspouts.

TI Parameterization of EPIC crop model for simulation of cotton growth in South Texas SO JOURNAL OF AGRICULTURAL SCIENCE LA English DT Article ID RADIATION-USE EFFICIENCY; PHOTOSYNTHETICALLY ACTIVE RADIATION; LEAF-AREA; CULTIVARS; ACCUMULATION; NITROGEN; YIELD AB Parameterization in crop simulation modelling is a general procedure to calibrate a crop model to explore the best lit for a certain regional environment of interest. The parameters of radiation use efficiency (RUE) and light interception coefficient (k) of cotton (Gossypium hirsutum) for different cultivars were estimated under various irrigation conditions in South Texas in 2006 and 2007. A calibration procedure was then performed for determination of RUE using the environmental policy impact calculator (EPIC) crop model (Williams et al. 1994). This was carried out using data sets obtained separately from the data for parameter estimation. The estimates of k and RILE were 0.63 and 2-5g/MJ, respectively, which were determined based on the field experiment and variation of simulated lint yield. When the parameters were used with EPIC to simulate the variability in lint yields, a correlation coefficient of 0-86 and root mean square error (RMSE) of 022 t/ha were obtained, presenting no significant differences (paired t-test: P-0.282) between simulation and measurement. The results demonstrate that tin appropriate estimate of the model parameters including RUF, is essential in order to make crop models reproduce field conditions properly in simulating crop growth, yield and other variables.

The objective of this study was to determine the combined effects of elevated temperature and CO2 during seed-filling of parent plants on seed composition, subsequent seedling emergence and seedling vigour of red kidney bean (Phaseolus vulgaris). Plants of cultivar 'Montcalm', were grown at daytime maximum/nighttime minimum sinusoidal temperature regimes of 28/18 and 34/24 degrees C at ambient CO2 (350 mu mol mol(-1)) and at elevated CO2 (700 mu mol mol(-1)) from emergence to maturity. Seed size and seed composition at maturity and subsequent per cent emergence, early seedling vigour (rate of development) and seedling dry matter production were measured. Elevated CO2 did not influence seed composition, emergence, or seedling vigour of seeds produced either at 28/18 or 34/24 degrees C. Seed produced at 34/24 degrees C had smaller seed size, decreased glucose concentration, but significantly increased concentrations of sucrose and raffinose compared to 28/18 degrees C. Elevated growth temperatures during seed production decreased the subsequent per cent emergence and seedling vigour of the seeds and seedling dry matter production of seed produced either at ambient or elevated CO2.

The innate immune response to bacterial penetration of the mammary gland is evoked within hours of infection, and the rapidity and magnitude of this response have been demonstrated to influence the resolution of this disease. Cytokines and other mediators of inflammation are known to play critical roles in the innate immune response to intramammary infection. The objectives of this review are to summarize the current understanding of the cytokine response to intramammary infection, highlight recent findings identifying differences in the cytokine response to various bacterial pathogens, and discuss future research directions that will increase our knowledge of the role of inflammatory mediators in predicting and governing the outcome of mastitis.

Preadipocytes and adipocytes are important in establishing the overall fatness of a carcass, as well as being the main contributors to the marbling component needed for consumer preference of meat products. Although some fat accumulation is essential, any excess fat that is deposited into adipose depots other than the marbling fraction is energetically unfavorable and reduces efficiency of production. Hence, this review is focused on current knowledge about the biology and regulation of the important cells of adipose tissue: preadipocytes and adipocytes. C1 [Dodson, M.

TI Urea metabolism in beef steers fed tall fescue, orchardgrass, or gamagrass hays SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE fescue; gamagrass; orchardgrass; steer; urea metabolism ID INTAKE PROTEIN SUPPLEMENTATION; LOW-QUALITY FORAGE; FED ENDOPHYTE-FREE; NITROGEN-METABOLISM; RECYCLED UREA; MICROBIAL USE; KINETICS; DEGRADATION; SHEEP; DISAPPEARANCE AB Two experiments were conducted to assess effects of endophyte treatments (Exp. 1), forage species (Exp. 2), and supplementation (Exp. 2) on urea production, excretion, and recycling in beef steers. Infusion of (15,15)N-urea and enrichment of urea in urine samples were used to calculate urea-N entry and recycling to the gut. Acceptably stable enrichment of (15)N-urea in urine was obtained after 50 h of intrajugular infusion of (15,15)N-urea, indicating that valid data on urea metabolism can be obtained from steers fed forages twice daily. After adjustment by covariance for differences in N intake among treatments in Exp. 1, steers fed endophyte-infected tall fescue had less (P < 0.10) urea-N entry, recycling to the gut, and return of recycled urea-N to the ornithine cycle than those fed endophyte-free or novel endophyte-infected tall fescue. However, urea-N urinary excretion or return to the gut was similar among endophyte treatments when expressed as a proportion of urea-N entry. Urea-N entry and return to the gut in Exp. 2 was similar in steers fed gamagrass or orchardgrass hay after adjustment by covariance for differences in N intake. Less (P < 0.01) urinary excretion, expressed as grams per day or as a proportion of urea-N entry, with gamagrass than with orchardgrass was associated with faster in vitro NDF-N digestion with gamagrass. Supplementation of gamagrass or orchardgrass with 1.76 kg/d of readily fermentable fiber and starch decreased urea entry (P < 0.06) and urinary excretion of urea (P < 0.01). Interactions between hay source and supplement reflected a greater response to supplementation for steers fed orchardgrass than for those fed gamagrass. After adjustment for differences among treatments in N supply, results of both experiments support the concept of improved N use in response to increased carbohydrate fermentability in the rumen, due either to inherent differences in forage fiber or to supplementation with readily fermentable carbohydrate (starch or fiber). Closer coordination of ruminal fermentation of carbohydrate and N sources provided greater and more efficient capture of dietary N as tissue protein in forage-fed steers. C1 [Huntington, G.

TI Postnatal piglet husbandry practices and well-being: The effects of alternative techniques delivered separately SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE growth; pain; physiology; pig; routine processing; vocalization ID TEETH RESECTION PROCEDURES; TAIL DOCKING; TOOTH RESECTION; BEHAVIORAL-RESPONSES; FARROWING CRATES; SUCKLING PIGLETS; STRESS HORMONES; CANINE TEETH; YOUNG-PIGS; CASTRATION AB The aim of this study was to evaluate stress responses evoked by 2 alternative methods for performing the following processing procedures: 1) teeth resection-clipping vs. grinding; 2) tail docking cold vs. hot clipping; 3) identification-ear notch vs. tag; 4) iron administration-injection vs. oral; 5) castration-cords cut vs. torn. Eight to 10 litters of 8-, 2-, and 3-d-old piglets were assigned to each procedure. Within each litter, 2 piglets were assigned to 1 of 4 possible procedures: the 2 alternative methods, a sham procedure, and a sham procedure plus blood sampling. Blood was sampled before processing and at 45 min, 4 h, 48 h, 1 wk, and 2 wk postprocedure and assayed for cortisol and beta-endorphin. Procedures were videotaped and analyzed to evaluate the time taken to perform the procedure and the number of squeals, grunts, and escape attempts. Vocalizations were analyzed to determine mean and peak frequencies and duration. Piglets were weighed before the procedure and at 24 h, 48 h, 1 wk, and 2 wk afterward. Lesions were scored on a scale of 0 to 5 on pigs in the identification, tail docking, and castration treatments at 24 h, 1 wk, and 2 wk postprocedure. For teeth resection, grinding took longer than clipping and resulted in greater cortisol concentration overall, poorer growth rates, and longer vocalizations compared with pigs in the control treatment (P < 0.05). For tail docking, hot clipping took longer, and hot-clipped piglets grew slower than cold-clipped piglets (P < 0.05). Hot clipping also resulted in longer and higher frequency squealing compared with pigs in the control treatment (P < 0.01). For identification, ear notching took longer than tagging, and ear-notched piglets had worse wound scores than tagged piglets (P < 0.05). Cortisol concentrations at 4 h also tended to be greater for ear-notched piglets (P < 0.10). Ear notching evoked calls with higher peak frequencies than the control treatments. For iron administration, oral delivery took numerically longer than injecting, but there were no significant differences between injecting and oral delivery for any of the measures. For castration, tearing took longer than cutting the cords (P < 0.05), but beta-endorphin concentrations at 45 min postprocedure were greater for cut piglets. When measures of behavior, physiology, and productivity were used, the responses to teeth resection, tail docking, and identification were shown to be altered by the procedural method, whereas responses to iron administration and castration did not differ. The time taken to carry out the procedure would appear to be an important factor in the strength of the stress response. C1 [Marchant-Forde, J. N.; Lay, D. C., Jr.; McMunn, K. A.; Cheng, H.

TI Investigation of the susceptibility of various strains of mice to methyllycaconitine toxicosis SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE Delphinium; larkspur; lethal dose 50%; methyllycaconitine; mouse strain ID NICOTINIC RECEPTOR; BINDING-SITES; ALKALOIDS; MOUSE; ACETYLCHOLINE; EXPRESSION; ANTAGONIST; TOXICITY AB Although the mechanism of action for larkspur alkaloids has been described, little information is available on the variation of the physiological response of individual animals to larkspur alkaloids. Anecdotal observations and pilot studies in cattle indicate that there is animal-to-animal variation in response to a debilitating dose of larkspur alkaloids. The objective of this study was to determine whether there is variation in susceptibility of different strains of mice to larkspur alkaloid toxicosis and to identify factors responsible for the variation that could then be used as a model for studies in cattle. The acute toxicity of methyllycaconitine (MLA) in 9 different inbred strains of mice was compared. The rank order, from most to least susceptible, was A/J > B10 > FVB > BALB/c > C57Bl/6 > NZW > C3H > DBA > 129. The calculated LD(50) ranged from 3.3 +/- 0.2 to 5.8 +/- 0.8 mg/kg of BW. The toxicokinetic profiles of MLA in the susceptible A/J strain and the more resistant 129 strain were compared to determine whether their differences in susceptibility were due to differences in their ability to eliminate MLA. The differences in toxicokinetic variables observed did not explain the differences in susceptibility. The protein expression of various nicotinic acetylcholine receptor (nAChR) subunits was also compared between the more resistant 129 strain and the susceptible A/J strain. The 129 strain of mice had twice the amount of alpha 7 nAChR subunit expression as the A/J strain, which was in direct proportion to the approximately 2-fold difference in LD(50). There was also a significant difference (P < 0.05) in expression of the alpha 3 and alpha 5 nAChR subunits between the 129 and A/J strains, with the 129 strain having a greater expression in each case. These data suggest that the increased susceptibility of the A/J mice could be due to a reduced expression of nAChR subunits. Similar analyses need to be made in cattle to determine whether there is a difference between breeds in susceptibility to larkspur poisoning and to identify the factors that regulate their susceptibility to larkspur poisoning. This information would be useful for livestock producers in their breeding, culling, and grazing management programs to reduce or prevent larkspur poisoning on rangelands. C1 [Welch, K. D.; Green, B.

MicroRNA ( miRNA) are an emerging class of small RNA that regulate gene translation. However, the mechanisms by which miRNA regulate this process remain controversial. By altering posttranscriptional regulation, miRNA have a role in guiding developmental decisions, including cell fate, cell cycle progression, apoptosis, adipocyte differentiation, and processes that alter muscle development and growth. The role of miRNA in developmental decisions that affect animal biology is of significant interest, yet the current literature is limited in livestock models. Therefore, a review of the mechanisms by which miRNA alter gene translation and the current research evaluating miRNA in production livestock is needed.

Bacterial cultures in each of four biochemically different types of liquid media emitted different volatiles. Cultures in a medium containing uric acid as its primary nitrogen source emitted more ammonia and 2-nonanone than the other media. We postulate that the high production of ammonia was because of uricase activity by this uricase (+) strain. Regardless of media type, supernatants emitted more volatiles than preparations containing cells that had been removed from whole cultures and put into distilled water. Attractiveness varied little with biochemical make-up of the culturing medium although the uric acid and carbohydrate preparations were as a group more attractive than preparations made from the other two media. Supernatants and whole cultures generally were more attractive than cell preparations and non-inoculated media. Bacteria grown in aqueous uric acid-based media emitted volatiles similar but not identical to those emitted by bacteria grown on gel (agar or solid) uric acid-based media in Petri plates.

Up to date, the project has involved 35 participants from 29 countries and 26 species of fruit flies. Fourteen participants have concluded their evaluation of the process, and 11 of these 14, have deemed it to be successful. One participant has decided to implement the project on a larger scale. The 14 participants were, Argentina (Ceratitis capitata and Anastrepha fraterculus), Bangladesh (Bactrocera cucurbitae, C. capitata, and Bactrocera dorsalis), China (Fujia province) (B. dorsalis), Italy (C. capitata), Fiji (Bactrocera passiflorae), Kenya (Bactrocera invadens, Ceratitis cosyra), Mauritius (Bactrocera zonata and B. cucurbitae), Mexico (Anastrepha species), Philippines (Bactrocera philippinese), Thailand (Bactrocera correcta), Austria (C. capitata, Vienna 8 and A. fraterculus), Israel (Dacus ciliatus and C. capitata), South Africa (C. capitata, Vienna 8) and Australia (C. capitata). The Stellenbosch medfly mass-rearing facility in South Africa and the CDFA in Hawaii were two mass-scale rearing facilities that allowed us to demonstrate onsite rearing in a larger scale. Demonstrations were performed in CDFA in 2007, and in Stellenbosch, South Africa in 2008; both were found to be successful. The Stellenbosch medfly mass-rearing facility in South Africa decided to adopt the technology and is currently evaluating the quality control of the flies that were reared as larvae on a liquid diet.

DIPTERA; FLY DIPTERA; BRACONIDAE; ABUNDANCE; HAWAII; ASSOCIATIONS AB The biological attributes of three introduced species of parasitoids which attack the fruit fly Anastrepha ludens were evaluated. Larvae and eggs of A. ludens were exposed to larval parasitoids Diachasmimorpha longicaudata and D. tryoni and the egg parasitoid Fopius arisanus. Parasitoid longevity and fecundity were determined using larvae and eggs of A. ludens. Likewise, the parasitism rates of these parasitoid species in infested host fruits were recorded. The intrinsic rate of increase for F. arisanus was 0.1019 followed by D. tryoni with a rate of 0.1641 and D. longicaudata with the highest rate of 0.2233. Although F. arisanus females had the highest levels of fecundity, only 50% of them remained alive until reproductive age. These results in combination with the longer generation time (in comparison with D. longicaudata and D. tryoni), can be considered as the most important factors explaining F. arisanus reduced rate of increase. However, we note that oviposition activity caused egg mortality which reduced Anastrepha egg hatch by ca. 20%. This result suggests that F. arisanus has a high potential as a natural enemy of A. ludens, in accordance with our research efforts to develop a new F. arisanus strain specialized for development in Anastrepha eggs. The results show that D. tryoni is not a good candidate for biological control of Anastrepha. Meanwhile, D. longicaudata continues to be the most important exotic parasitoid for suppression of Anastrepha fruit fly populations.

TI Soil carbon and nitrogen in a Great Basin pinyon-juniper woodland: Influence of vegetation, burning, and time SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Carbon storage; Prescribed fire; Spatial heterogeneity; Woodland expansion ID PRESCRIBED FIRE; BIG SAGEBRUSH AB Much of the Great Basin, U.S. is currently dominated by sagebrush (Artemisia tridentate ssp. (Rydb.) Boivin) ecosystems. At intermediate elevations, sagebrush ecosystems are increasingly influenced by pinyon (Pinus monophylla Torr. & Frem.) and juniper (Juniperus osteospertna Torr.) expansion. Some scientists and policy makers believe that increasing woodland cover in the intermountain western US will create new carbon storage on the landscape; however, little is currently known about the distribution of carbon on these landscapes. This is especially true of below ground pools. Our objectives were to quantify the spatial distribution of soil carbon in expansion woodlands, and to determine prescribed fire's effect on soil C and N. We looked at two treatments (control and burn), three microsites (undertree, undershrub, and interspace), and four soil depths (0-8. 8-23, 23-38, and 38-52 cm). The study was conducted over a six year period with one year pre-fire and five years post-fire data. Results for both carbon and nitrogen were similar, indicating the close relationship between the two elements in this ecosystem. Undershrub microsites had higher soil C and N concentrations than interspace and undertree microsites: however, under tree microsites had higher C:N rat interspace and undershrub microsites. Carbon and nitrogen concentration tended to decrease with increasing depth at both control and burn sites. Prescribed burning caused immediate increases in surface soil C and N concentration, but over intermediate to longer periods of time no statistically detectable change in soil C or N content occurred from burning.

TI Ecophysiology of two Sonoran Desert evergreen shrubs during extreme drought SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Chlorophyll fluorescence; Drought; Larrea tridentata; Simmondsia chinensis; Standardized precipitation index; Photochemical efficiency ID ENERGY-DISSIPATION; MOJAVE DESERT; XANTHOPHYLL CYCLE; LARREA-TRIDENTATA; HIGH-TEMPERATURE; GAS-EXCHANGE; ELEVATED CO2; RESPONSES; LIGHT; STRESS AB Recent drought across the desert Southwest US may strongly affect the physiological functioning of evergreen desert species that maintain leaves through these dry periods. In July 2002 we compared the ecophysiological performance of the open-canopied, small-leaved creosotebush (Larrea tridentata) to the dense-canopied, more broad-leaved jojoba (Simmondsia chinensis) growing on a ridge-top, east- and west-facing slopes to assess how differences in leaf habit and exposure affect these species' ability to withstand severe drought. Standardized precipitation index (SPI) from 100 years precipitation data showed July 2002 rainfall was normal, but the 12-month period ending July 2002 was of extreme aridity (SPI = -2.71). Predawn water potentials were extremely low, and lower in jojoba (-8.1 to -9.5 MPa) than in Larrea (-6.6 to -9.4 MPa). Chlorophyll fluorescence showed jojoba had more consistent photochemical performance than Larrea across three exposures, having higher optimal photosystem II (PSII) efficiency (F(v)/F(m)), lower light-adapted PSII yield, and better ability to thermally dissipate light energy (i.e. higher NPQ), especially in inner-canopy jojoba leaves. These findings suggest jojoba may better cope with high light under drought conditions, and that canopy shading in jojoba may reduce high-light stress. Moreover, lower F(v)/F(m), NPQ and high PSII yields in Larrea was similar between east-facing and ridge-top locations, but achieved levels similar to jojoba on west-facing exposures. These findings suggest these drought-tolerant evergreens rely on different physiological mechanisms to cope with high light under extreme drought conditions. Published by Elsevier Ltd.

TI A DNase Encoded by Integrated Element CJIE1 Inhibits Natural Transformation of Campylobacter jejuni SO JOURNAL OF BACTERIOLOGY LA English DT Article ID HORIZONTAL GENE-TRANSFER; GUILLAIN-BARRE-SYNDROME; ESCHERICHIA-COLI; AEROMONAS-HYDROPHILA; EXTRACELLULAR DNASES; VIBRIO-CHOLERAE; DIVERSITY; BACTERIA; REVEALS; VIRULENCE AB The species Campylobacter jejuni is considered naturally competent for DNA uptake and displays strong genetic diversity. Nevertheless, nonnaturally transformable strains and several relatively stable clonal lineages exist. In the present study, the molecular mechanism responsible for the nonnatural transformability of a subset of C. jejuni strains was investigated. Comparative genome hybridization indicated that C. jejuni Mu-like prophage integrated element 1 (CJIE1) was more abundant in nonnaturally transformable C. jejuni strains than in naturally transformable strains. Analysis of CJIE1 indicated the presence of dns (CJE0256), which is annotated as a gene encoding an extracellular DNase. DNase assays using a defined dns mutant and a dns-negative strain expressing Dns from a plasmid indicated that Dns is an endogenous DNase. The DNA-hydrolyzing activity directly correlated with the natural transformability of the knockout mutant and the dns-negative strain expressing Dns from a plasmid. Analysis of a broader set of strains indicated that the majority of nonnaturally transformable strains expressed DNase activity, while all naturally competent strains lacked this activity. The inhibition of natural transformation in C. jejuni via endogenous DNase activity may contribute to the formation of stable lineages in the C. jejuni population.

The relative roles of recent and ancient biogeographical processes, relationships with plant hosts, and the timing of divergences that have shaped the current geographic distribution of the family are investigated. Africa, Australia, Neotropics, New Zealand, north temperate zone, Palaeotropics, Southeast Asia, South America, south temperate zone. We reconstruct a phylogeny of the Inocybaceae with a geological timeline using a relaxed molecular clock. Divergence dates of lineages are estimated statistically to test vicariance-based hypotheses concerning relatedness of disjunct ECM taxa. A series of internal maximum time constraints is used to evaluate two different calibrations. Ancestral state reconstruction is used to infer ancestral areas and ancestral plant partners of the family. The Palaeotropics are unique in containing representatives of all major clades of Inocybaceae. Six of the seven major clades diversified initially during the Cretaceous, with subsequent radiations probably during the early Palaeogene. Vicariance patterns cannot be rejected that involve area relationships for Africa-Australia, Africa-India and southern South America-Australia. Northern and southern South America, Australia and New Zealand are primarily the recipients of immigrant taxa during the Palaeogene or later. Angiosperms were the earliest hosts of Inocybaceae. Transitions to conifers probably occurred no earlier than 65 Ma. The Inocybaceae initially diversified no later than the Cretaceous in Palaeotropical settings, in association with angiosperms. Diversification within major clades of the family accelerated during the Palaeogene in north and south temperate regions, whereas several relictual lineages persisted in the tropics. Both vicariance and dispersal patterns are detected. Species from Neotropical and south temperate regions are largely derived from immigrant ancestors from north temperate or Palaeotropical regions. Transitions to conifer hosts occurred later, probably during the Palaeogene. C1 [Matheny, P. Brandon; Hibbett, David S.] Clark Univ, Dept Biol, Worcester, MA 01610 USA. [Aime, M.

We estimated the burden of fragility fractures by race/ethnicity, age, sex, and service site across five diverse and populous states. State inpatient databases for 2000 were used to describe hospital fracture admissions, and a Markov decision model was used to estimate annual fracture incidence and cost for populations >= 50 yr of age for 2005-2025 in Arizona (AZ), California (CA), Florida (FL), Massachusetts (MA), and New York (NY). In 2000, mean hospital charges for incident fractures varied 1.7-fold across states. For hip fracture, mean charges ranged from $16,700 (MA) to $29,500 (CA), length of stay from 5.3 (AZ) to 8.9 days (NY), and discharge rate to long-term care from 43% (NY) to 71% (CA). In 2005, projected fracture incidence rates ranged from 199 (CA) to 266 (MA) per 10,000. Total cost ranged from $270 million (AZ) to $1,434 million (CA). Men accounted for 26-30% of costs. Across states, hip fractures constituted on average 77% of costs; "other" fractures (e.g., leg, arm), 10%; pelvic, 6%; vertebral, 5%; and wrist, 2%. By 2025, Hispanics are projected to represent 20% of fractures in AZ and CA and Asian/Other populations to represent 27% of fractures in NY. In conclusion, state initiatives to prevent fractures should include nonwhite populations and men, as well as white women, and should address fractures at all skeletal sites. Interstate variation in service utilization merits further evaluation to determine efficient and effective disease management strategies.

ERK5-mediated phosphorylation of the transcription factor Ets-1 enhanced 1,25(OH)(2)D(3)-mediated CYP24 gene transcription in proliferating but not differentiated Caco-2 cells due to reduced levels of ERK5 and Ets-1 (total and phosphoprotein levels) in differentiated cells. MEK inhibition reduced 1,25(OH)(2)D(3)-induced 3X-VDRE promoter activity but had no impact on the association of vitamin D receptor (VDR) with chromatin suggesting a role for co-activator recruitment in ERK-modulation of vitamin ID-regulated CYP24 gene activation. Chromatin immunoprecipitation assays revealed that the ERK 1/2 target, mediator 1 (MED1), is recruited to the CYP24, but not the TRPV6, promoter following 1,25(OH)(2)D(3) treatment. MED1 phosphorylation was sensitive to activators and inhibitors of the ERK 1/2 signaling and MED1 siRNA reduced 1,25(OH)(2)D(3)-regulated human CYP24 promoter activity. This suggests ERK 1/2 signaling enhances 1,25(OH)(2)D(3) effects on the CYP24 promoter by MED1-mediated events. Our data show that there are both promoter-specific and cell stage-specific roles for the ERK signaling pathway on 1,25(OH)(2)D(3)-mediated gene induction in enterocyte-like Caco-2 cells.

TI Altered Olfactory Receptor Neuron Responsiveness Is Correlated with a Shift in Behavioral Response in an Evolved Colony of the Cabbage Looper Moth, Trichoplusia ni SO JOURNAL OF CHEMICAL ECOLOGY LA English DT Article DE Lepidoptera; Electrophysiology; Pheromone; Evolution; Behavior; Olfaction; Antenna ID PHEROMONE COMMUNICATION-SYSTEMS; EUROPEAN CORN-BORER; SEX-PHEROMONE; EVOLUTIONARY SHIFTS; BLEND; COMPONENTS; OSTRINIA; MALES; ANTAGONISM; MUTANT AB There is little understanding of how sex pheromone blends might change during speciation events. For the cabbage looper, Trichoplusia ni, there is a mutant laboratory strain that has exhibited characteristics of a shift to a new pheromone blend. Mutant females produce a blend that is significantly different from wild-type females in having a much higher proportion of a minor pheromone component and lower quantity of the major component. Males in this colony have changed over the years to become more broadly tuned and fly upwind equally well to both the wild-type and mutant female pheromone blends. They also exhibit reduced overall sensitivity to pheromone, flying upwind to either blend at a lower success rate than is typical when wild-type males respond to the wild-type blend. Using single-cell recordings, we examined the olfactory receptor neurons (ORNs) of males from evolved and wild-type colonies for evidence of changes in response characteristics that might explain the above-described behavioral evolution. We found that in evolved-colony males the ORNs tuned to the major sex pheromone component exhibited a somewhat lower responsiveness to that compound than the ORNs of wild-type males. In addition, the minor pheromone component, emitted at excessively high rates by mutant females, elicited a drastically reduced ORN responsiveness in evolved-colony males compared to wild-type males. This alteration in ORN responsiveness may be responsible for allowing evolved males to tolerate the excessive amounts of the minor pheromone component in the mutant female blend, which would normally antagonize the upwind flight of unevolved males. Thus, peripheral olfactory alterations have occurred in T. ni males that are correlated with the evolution of the more broadly tuned, but less sensitive, behavioral response profile.

Although pheromone-based tools have become useful in the management of other beetle pests, no pheromone was known for A. diaperinus, and this study sought to develop basic pheromone information. Volatiles were collected in the laboratory from groups of male and female A. diaperinus maintained on poultry food (chick starter mash). Gas chromatographic-mass spectrometric analysis of volatiles collected from feeding males and females revealed five male-specific compounds that were identified as (R)-(+)-limonene, (E)-beta-ocimene, (S)-(+)-linalool, (R)-(+)-daucene, and 2-nonanone. Emission of these began 1-2 weeks after adult emergence and could continue for at least 1 year, ceasing and resuming in response to changes in food availability and quality and other factors. No female-specific compounds were discovered. A synthetic blend of the five male compounds was attractive to both sexes in poultry production facilities in Illinois and Arkansas, indicating that the blend functions as an aggregation pheromone, but it is not yet known whether all five compounds are required for activity. A new pitfall trap is described for field use. C1 [Bartelt, Robert J.; Zilkowski, Bruce W.; Cosse, Allard A.] ARS, USDA, NCAUR, Crop BioProtect Res Unit, Peoria, IL 61604 USA. [Steelman, C.

Eight field trials were conducted in mature pine stands in Alabama, Florida, Georgia, North Carolina, and South Carolina. Funnel traps baited with ethanol lures (release rate, about 0.6 g/day at 25-28A degrees C) were attractive to ten species of ambrosia beetles (Ambrosiodmus tachygraphus, Anisandrus sayi, Dryoxylon onoharaensum, Monarthrum mali, Xyleborinus saxesenii, Xyleborus affinis, Xyleborus ferrugineus, Xylosandrus compactus, Xylosandrus crassiusculus, and Xylosandrus germanus) and two species of bark beetles (Cryptocarenus heveae and Hypothenemus sp.). Traps baited with (-)-alpha-pinene lures (release rate, 2-6 g/day at 25-28A degrees C) were attractive to five bark beetle species (Dendroctonus terebrans, Hylastes porculus, Hylastes salebrosus, Hylastes tenuis, and Ips grandicollis) and one platypodid ambrosia beetle species (Myoplatypus flavicornis). Ethanol enhanced responses of some species (Xyleborus pubescens, H. porculus, H. salebrosus, H. tenuis, and Pityophthorus cariniceps) to traps baited with (-)-alpha-pinene in some locations. (-)-alpha-Pinene interrupted the response of some ambrosia beetle species to traps baited with ethanol, but only the response of D. onoharaensum was interrupted consistently at most locations. Of 23 species of ambrosia beetles captured in our field trials, nine were exotic and accounted for 70-97% of total catches of ambrosia beetles. Our results provide support for the continued use of separate traps baited with ethanol alone and ethanol with (-)-alpha-pinene to detect and monitor common bark and ambrosia beetles from the southeastern region of the US.

The test sets consist of 15 conformers of alpha- and beta-D-allopyranose, 15 of 3,6-anhydro-4-O-methyl-D-galactitol, and four Of beta-D-glucopyranose. For each set, conformational energies varied by about 7 kcal/mol. Results obtained with the Hartree-Fock method, with pure density functional approximations (DFAs) like LSDA, PBEsol, PBE, and TPSS and with hybrid DFAs like B3PW91, B3LYP, PBEh, and M05-2X, were then compared to the reference and local MP2 relative energies. Basis sets included 6-31G*, 6-31G**, 6-31+G*, 6-31+G**, 6-311+G**, 6-311++G**, cc-pVTZ(-f), cc-pVTZ, and aug-cc-pVTZ(-f). The smallest basis set that gives good DFA relative energies is 6-31+G**, and more converged results can be obtained with 6-311+G**. The optimized geometries obtained from a smaller basis set, 6-31+G*, were useful for subsequent single point energy calculations with larger basis sets. The best agreement with MP2 was shown by M05-2X, but only when using a dense DFT grid. The popular B3LYP functional is not the best for saccharide conformational studies. The B3PW91 functional gives systematically better results, but other hybrid functionals like PBEh or TPSSh are even better. Overall, the nonempirical PBE GGA and TPSS meta-GGA functionals also performed better than B3LYP. C1 [Csonka, Gabor I.] Tech Univ Budapest, Dept Inorgan & Analyt Chem, H-1521 Budapest, Hungary.

Objective: Our objective was to determine the relationship between SR-BI protein and HDL-C levels in humans. Design: This was a prospective study of adults with hyperalphalipoproteinemia. Fasting blood was obtained for lipid and lipoprotein measurement, genomic DNA, and monocyte-derived macrophages. SR-BI protein levels were measured by Western blots, and SR-BI activity was measured by cholesteryl ester (CE) uptake of each donor's radiolabeled HDL with their monocyte-derived macrophages, or by degradation and specific cell association of dual-labeled HDL in vitro. Setting: The study was performed in a tertiary university teaching hospital. Results: The mean age was 57.2 +/- 10.9 yr (n = 65). SR-BI protein levels were inversely associated with HDL-C levels (P < 0.002), HDL particle size (P < 0.05), and positively associated with CE uptake (P < 0.004); there was no association with plasma apolipoprotein levels. SR-BI protein levels (P = 0.01) were independent predictors of HDL-C levels. Subjects who were carriers of the A allele for the rs4238001 (glycine to serine at position 2) polymorphism [ single nucleotide polymorphism (SNP)] had lower SR-BI protein levels (P = 0.01), whereas carriers of the C allele for the rs2278986 SNP also had lower SR-BI protein levels (P = 0.02). Body mass index (P = 0.05), rs4238001 (P = 0.01), and rs2278986 (P = 0.01) SNPs were independent predictors of SR-BI protein levels. In vitro studies of murine macrophages stably expressing the glycine to serine at position 2 SNP showed less degradation (P < 0.0004) and specific cell association (P < 0.0004) of [(125)I, (3)H]-CE-labeled HDL. Conclusions: SR-BI protein has an independent effect on HDL-C levels in women with hyperalphalipoproteinemia. Two SNPs were significantly associated with lower SR-BI protein levels.

The role of alpha(S2)-CN in casein micelles has not been studied in detail in part because of a lack of structural information on the molecule. Interest in the utilization of this molecule in dairy products and nutrition has been renewed by work in 3 areas: biological activity via potentially biologically active peptides, functionality in cheeses and products, and nutrition in terms of calcium uptake. To help clarify the behavior of alpha(S2)-CN in its structure-function relationships in milk and its possible applications in dairy products, this paper reviews the chemistry of the protein and presents a working 3-dimensional molecular model for this casein. The model was produced by threading the backbone sequence of the protein onto a homologous protein: chloride intracellular channel protein-4. Overall, the model is in good agreement with experimental data for the protein, although the amount of helix may be over-predicted. The model, however, offers a unique view of the highly positive C-terminal portion of the molecule as a surface-accessible area. This region may be the site for interactions with kappa-carrageenan, phosphate, and other anions. In addition, most of the physiologically active peptides isolated from alpha(S2)-CN occur in this region. This structure should be viewed as a working model that can be changed as more precise experimental data are obtained. C1 [Farrell, H. M., Jr.; Malin, E. L.; Brown, E.

Although information is available on the effects of forage protein-binding polyphenols on small ruminant production and manure excretion, little information is available for dairy cattle. The objective of this study was to compare fecal and urinary N excretion of diets formulated with alfalfa (Medicago sativa L.) silage versus condensed tannin-containing birdsfoot trefoil (Lotus corniculatus) or o-quinone-containing red clover (Trifolium pratense L.) silages. Significantly higher concentrations of N were excreted in urine by lactating Holstein dairy cows fed red clover and low-tannin birdsfoot trefoil (8.2 g/L) than by cows fed high-tannin birdsfoot trefoil or alfalfa (7.1 g/L). Fecal N concentrations were similar (33.6 g/kg) among all diets. Dairy cows fed red clover had lower rates of urinary N excretion (5.0 g/h) compared with other forages (6.6 g/h). Fecal N excretion rates were lowest for red clover (4.1 g/h), intermediate for alfalfa (5.8 g/h), and greatest for cows fed high- and low-tannin birdsfoot trefoil (6.4 g/h). The ratio of fecal N to urinary N was highest for high- tannin trefoil, lowest for alfalfa and red clover, and higher in excreta collected in morning than evening. Concentrations of neutral detergent fiber (NDF) in feces, of N in NDF (NDIN) and acid detergent fiber (ADIN), and relative amounts of NDIN and ADIN excreted in feces were significantly higher from cows fed high- tannin birdsfoot trefoil than the other silage types. Study results imply that collection of excreta for environmental studies needs to consider forage polyphenol and diurnal effects on chemistry of dairy excreta. C1 [Powell, J. M.; Broderick, G.

Health and production data from 398 commercial dairy herds were used. Disease traits were defined in binary form for individual lactations considering mastitis only during the first 100 d in milk (MAST1), only after 100 d in milk (MAST2), and at any stage of lactation (MAST), and reproductive disorders (REPRO), metabolic disorders (METAB), and lameness (LAME). The persistencies were defined to be uncorrelated with 305-d yields. Impact of the diseases on PMY and PFY were investigated separately in first (FL) and later (LL) lactations. Phenotypic associations of PMY and PFY with likelihood of diseases in current and subsequent lactations were examined using odds ratios from a logistic regression model. Linear-threshold sire-maternal grandsire models were used to estimate genetic correlations of displaced abomasums (DA), ketosis (KET), metritis (MET), MAST, MAST1, and MAST2 with PMY and PFY across parities. Metabolic diseases and REPRO had significantly positive relationships with PMY and PFY in both FL and LL. Significantly greater PMY and PFY were associated with MAST1 in LL. Significantly lower PMY and PFY were related to MAST2 in both FL and LL, whereas cows affected by MAST had significantly less persistent lactations. Incidence of MAST and MAST2 decreased with increasing PMY and PFY in the present and previous lactation. Heritability of disease incidences were 0.03 (DA), 0.01 (KET), 0.10 (MAST), 0.02 to 0.05 (MAST1), 0.02 (MAST2), and 0.04 to 0.10 (MET). Displaced abomasum, KET, MAST, MAST1, and MET had unfavorable genetic correlations of 0.35, 0.46, 0.17, 0.02, and 0.27 with PMY, and 0.16, 0.21, 0.07, 0.06, and 0.12 with PFY, respectively. Favorable genetic correlations were found for MAST2 with PMY (-0.24) and PFY (-0.04). Results suggest that diseases in early lactation increase persistency of milk and fat yield. Selection for greater lactation persistency must consider these antagonistic relationships. C1 [Appuhamy, J. A. D. R. N.; Cassell, B.

Previous prediction programs were limited to the 305-d standard used since 1935. Best prediction was implemented in 1998 to calculate lactation records in USDA genetic evaluations, replacing the test interval method used since 1969 to calculate lactation records. Best prediction is more complex but also more accurate, particularly when testing is less frequent. Programs were reorganized to output better graphics, give users simpler access to options, and provide additional output, such as BP of daily yields. Test-day data for 6 breeds were extracted from the national dairy database, and lactation lengths were required to be >= 500 d (Ayrshire, Milking Shorthorn) or >= 800 d (all others). Average yield and SD at any day in milk (DIM) were estimated by fitting 3-parameter Wood's curves (milk, fat, protein) and 4-parameter exponential functions (somatic cell score) to means and SD of 15-(>= 300 DIM) and 30-d (>300 DIM) intervals. Correlations among TD yields were estimated using an autoregressive matrix to account for biological changes and an identity matrix to model daily measurement error. Autoregressive parameters (r) were estimated separately for first (r = 0.998) and later parities (r = 0.995). These r values were slightly larger than previous estimates due to the inclusion of the identity matrix. Correlations between traits were modified so that correlations between somatic cell score and other traits may be nonzero. The new lactation curves and correlation functions were validated by extracting TD data from the national database, estimating 305-d yields using the original and new programs, and correlating those results. Daily BP of yield were validated using daily milk weights from on-farm meters in university research herds. Correlations ranged from 0.900 to 0.988 for 305-d milk yield. High correlations ranged from 0.844 to 0.988 for daily yields, although correlations were as low as 0.015 on d 1 of lactation, which may be due to calving-related disorders that are not accounted for by BP. Correlations between 305-d yield calculated using 50-d intervals from 50 to 250 DIM and 305-yield calculated using all TD to 500 DIM increased as TD data accumulated. Many cows can profitably produce for >305 DIM, and the revised program provides a flexible tool to model these records. C1 [Cole, J. B.; Null, D. J.; VanRaden, P.

TI Dynamics of endemic infectious diseases of animal and human importance on three dairy herds in the northeastern United States SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE infection dynamics; dairy herd; longitudinal study; epidemiology and food safety ID AVIUM SUBSP PARATUBERCULOSIS; ESCHERICHIA-COLI O157-H7; FARM ENVIRONMENT; FOOD SAFETY; SALMONELLA; CATTLE; CAMPYLOBACTER; PREVALENCE; LISTERIA; US AB Endemic infectious diseases in dairy cattle are of significant concern to the industry as well as for public health because of their potential impact on animal and human health, milk and meat production, food safety, and economics. We sought to provide insight into the dynamics of important endemic infectious diseases in 3 northeastern US dairy herds. Fecal samples from individual cows and various environmental samples from these farms were tested for the presence of major zoonotic pathogens (i.e., Salmonella, Campylobacter, and Listeria) as well as commensal bacteria Escherichia coli and enterococci. Additionally, the presence of Mycobacterium avium ssp. paratuberculosis was tested in fecal and serum samples from individual cows. Test results and health and reproductive records were maintained in a database, and fecal, plasma, DNA, and tissue samples were kept in a biobank. All bacteria of interest were detected on these farms and their presence was variable both within and between farms. The prevalence of Listeria spp. and L. monocytogenes in individual fecal samples within farm A ranged from 0 to 68.2% and 0 to 25.5%, respectively, over a period of 3 yr. Within farm B, continuous fecal shedding of Salmonella spp. was observed with a prevalence ranging from 8 to 88%; Salmonella Cerro was the predominant serotype. Farm C appeared less contaminated with Salmonella and Listeria, although in the summer of 2005, 50 and 19.2% of fecal samples were positive for Listeria and L. monocytogenes, respectively. The high prevalence of E. coli (89 to 100%), Enterococcus (75 to 100%), and Campylobacter (0 to 81%) in feces suggested they were ubiquitous throughout the farm environment. Fecal culture and ELISA results indicated a low prevalence of Mycobacterium avium ssp. paratuberculosis infection in these farms (0 to 13.6% and 0 to 4.9% for culture-positive and ELISA-positive, respectively), although the occasional presence of high shedders was observed. Results have major implications for food safety and epidemiology by providing a better understanding of infectious disease dynamics on dairy farms. Comprehensive understanding of these infections may lead to better farm management practices and pathogen reduction programs to control and reduce the on-farm contamination of these pathogens and to prevent their further entry into the food-chain.

We examined the effects of levels of the parasitic mite Varroa destructor Anderson & Trueman, the endoparasitic mite Acarapis woodi (Rennie), the gut parasite Nosema (species not determined) in samples from bees in 48 packages, and levels of adult drones in the same packages oil corresponding levels of those same traits in the fall in colonies that developed from those 48 packages. After package installation, we measured the rate of queen failure, the removal of freeze-killed brood (an assay to assess hygienic behavior), varroa-sensitive hygiene, and short-term weight gain in all colonies. We examined the correlations among these traits and the effect of initial package conditions and package-type on the expression of these traits. In general, differences among sources were not significant, except that we did observe significant differences in the proportion of mite infected worker brood in the fall. There was no significant difference in weight gain in colonies established from nosema-infected packages versus those established from noninfected packages. Freeze-killed hygienic behavior and varroa-sensitive hygienic behavior were positively correlated, suggesting that both traits could be selected simultaneously. Neither trait was correlated with colony weight gain, suggesting that both traits could be selected without compromising honey production.

To determine whether modified dietary conditions might improve predation, newly eclosed adult female Orius promilio (Champion) were fed on E. kuchmiella eggs plus encapsulated water. encapsulated 5% sucrose solution only, or encapsulated water only for periods of 24, 48, or 72 h. Feeding activity was assessed by measuring the area of a crop in digital images of dissected digestive tracts. Adult females fed continuously on eggs had larger crops than did females on encapsulated sucrose solution. When females were prefed encapsulated water or sucrose and then fed 3 h on eggs. their crops became higly engorged and were larger than those in females fed continuously on eggs for the same periods. IN behavioral choice tests, adult females prefed on encapsulated water or 5% sucrose solution spent a larger portion of time in contact with eggs. presumably feeding, whereas females prefed on eggs showed no preference between eggs or encapsulated water. After overnight shipping females prefed on water or sucrose and held for 48 h total consumed 3.6- and 4.3-fold, respectively, more western flowerthrips. Frankliniella occidentalis (pergande), in 3h than those prefed on eggs. Survival rates when prefed on sugar or water were comparable with prefeeding on eggs. Thus inundative releases of Orius can be enhanced by starvation, because females initially feed much more voraciously after shipment with no apparent reduction in fitness.

A heating block system was used to determine the thermal death kinetics of the four fruit fly species. Treatments consisted of heating the fruit fly life stages to 44, 46, 48, and 50 degrees C and holding for different times ranging from 0 to 120 min depending on the thermal mortality response and time required to obtain 100% mortality for each species and life stage. The 0.5-order kinetic model had the best fit to the survival ration for all the treatment temperatures and was used to predict lethal times. The thermal death time (TDT) curves showed a tolerance order of Mediterranean fruit fly eggs <= third instars at 44, 46, and 50 degrees C. third instars <= eggs at 48 degrees C. and wild third instars < the laboratory-reared third instars. Comparison between Mediterranean fruit fly third instar thermotolerance from Hawaii and Israel showed that Israel Mediterranean fruit fly was more thermotolerant. A comparison of minimum treatment times at a given temperature required to obtain 100% mortality of laboratory-reared Malaysian, Mediterranean (Hawaii and Israel strains), melon, Mexican and oriental fruit fly eggs or third instars and wild mediterranean fruit fly (Hawaii strain) eggs or third instars showed that oriental fruit fly was the most thermotolerant among the third instars, and the difference in heat tolerance between third instars and eggs was negligible at 50 degrees C.

In comparative tests standard Jackson traps with naled and the Hawaii fruit fly areawide pest management (AWPM) trap with 2.2-dichorovinyl dimethyl phosphate (DDVP) insecticidal strips outperformed traps without an insecticide. Addition of the reduced risk insecticide spinosad did not increase trap capture significantly compared with Jackson traps without an insecticide. Captures in AWPM traps with DDVP compared favorably with those for the Jackson trap with liquid naled (the Florida standard). IN subsequent tests, captures with solid Farma Tech wafer dispensers with ME or C-L and DDVP placed inside Jackson and AWPM traps were equal to those for a Jackson trap with naled, currently used for detection of ME and C-L responding fruit flies in Florida. Farma Tech ME and C-L wafers with DDVP would be more convenient and safer to handle than current liquid insecticide formulations (e.g. naled) used for detection programs in Florida.

Diabrotica virgifera virgifera Leconle (Coleoptera: Chrysomelidae), were extracted from living corn Zea mays I roots with acetone. Larvae were exposed to corn roots or to an acetone extract of corn roots and then transferred into a bioassay arena where their movements were tracked and recorded. After a 5-min exposure to live corn roots, larvae produced highly convoluted tracks that were indicative of a localized search behavior and these distinctive tracks were also produced by larvae exposed to an acetone extract of corn roots, larvae exposed to filter paper control moved in relatively straight paths that were indicative of ranging behavior. Larval tracks were recorded by means of a video camera and tracking software and four parameters of movement were used to quantify the tracks mean turn angle, mean meander total distance and maximum distance from origin. For every parameter measured, tracks resulting from exposure to the control were significantly different from tracks resulting from exposure to live corn roots and to all doses of the corn root extract. In a separate experiment, larvae exposed to corn root pieces or corn root juice exhibited the localized search behavior, but larvae exposed to oat root pieces and oat root juice (nonhost) exhibited ranging behavior.

TI Technique to Assess Effectiveness of Control Tactics Against Ostrinia nubilalis (Lepidoptera: Crambidae) in Whorl-Stage Corn SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE European corn borer; Bacillus thuringiensis; evaluation technique; model; whorl-stage ID PYRALIDAE EGG MASSES; BORER LEPIDOPTERA; BACILLUS-THURINGIENSIS; FIELD CORN; LARVAE AB Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae) is one of the most damaging insect pests of corn. Studies were conducted to determine whether live larval counts obtained from corn whorls were predictive of the amount of larval tunneling that would result in the stalk of the plant 40 d later at the end of larval development. Whorls from plants treated with Dipel 10G (6,400 IU per whorl) and untreated controls, both infested with O. nubilalis neonates, were evaluated for the number of live larvae in 50 whorls 5, 7, 9 and 12 d after Bacillus thuringiensis (Berliner) (Bacillales: Bacillaceae) application. Forty days after larval infestation, 25 plants from each plot were split from tassel to base, and the length of larval tunneling was recorded. There was a strong relationship between numbers of live larvae in the plant whorl and the length of larval tunneling that resulted. While linear at each location, there was significant variation in the relationship among locations, indicating that comparisons could not be made between years or locations within a year. Blocks within a location on a give year did not vary significantly and reproducible results were obtained each year within a given location as well as on any of the whorl pulling dates evaluated. Because of its ease of use, predictability, and rapid return of results, we propose this technique as an additional method to shot-hole feeding and stalk splitting to evaluate the effectiveness of O. nubilalis management strategies.

As part of a coordinated country-wide effort, an extensive survey of B. tabaci biotypes was conducted in Florida, with the cooperation of growers and state and federal agencies, to monitor the introduction and distribution of both the B and Q biotypes. The biotype status of submitted B. tabaci samples was determined by polymerase chain reaction (PCR) amplification and sequencing of a 700-800-bp mitochondrial cytochrome oxidase I small subunit (mtCOI) gene fragment. PCR amplification, and size determination of tow unique microsatellite markers and esterase zymogram analysis. One hundred and eighty collections were sampled from 23 countries. Of these samples, 58% were from vegetables, 37% were from ornamentals, and 5% were from peanuts, alfalfa, and weeds. Eighteen percent of all collections were found to be the Q biotype that came from greenhouse grown ornamental and herbs located in six countries. Sequence comparison of the mtCOI gene identified three separate haplotypes within Florida that were defined as Q1, Q2, and Q3 haplotypes, supporting the conclusion that the Q biotype must have entered Florida through at least two separate introductions. Our data also show that two microsatellite markers are a cost-effective diagnostic alternative for biotype identification with 100% concurrence with mtCOI sequence data. C1 [McKenzie, C.

TI Improved UNA Barcoding Method for Bemisia tabaci and Related Aleyrodidae: Development of Universal and Bemisia tabaci Biotype-Specific Mitochondrial Cytochrome c Oxidase I Polymerase Chain Reaction Primers SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE whitefly; mitochondria; cytochrome oxidase I; Bemisia tabaci ID WHITEFLIES HOMOPTERA; DNA MARKERS; RAPD-PCR; HEMIPTERA; IDENTIFICATION; POPULATIONS; GENNADIUS; POLYMORPHISMS; SEQUENCES; COLOMBIA AB Whiteflies heteropteraus in the family Aleyrodidae are globally distributed and severe agricultural pests. The mitochondrial cytochrome c oxidase I (mtCOI) sequence has been used extensively in whitefly phylogenetic comparisons and in biotype identification of the agriculturally important Bemisia tabaci (Gennadius) whitefly. Because of the economic importance of several whitefly genera and the invasive nature of the B and the Q biotypes of Bemisia tabaci, mtCOI sequence data are continually generated from sampled populations worldwide. Routine phylogenetic comparisons and biotype identification is done through amplification and sequencing of an approximate to 800-bp mtCOI DNA fragment. Despite its routine use published primers for amplification of this region are often inefficient for some B. tabaci biotypes and especially across whitefly species. Through new sequence generation and comparison to available whitefly mtCOI sequence data, a set of polymerase chain reaction (PCR) amplification primers (Btab-Uni primers) were identified that are more efficient at amplifying approximate to 748 bp of the approximate to 800-bp fragment currently used. These universal primers amplify an mtCOI fragment from numerous B. tabaci biotypes and whitefly genera by using a singel amplification profile. Furthermore, mtCOI PCR primers specific for the B. Q and New World biotypes of B. tabaci were designed that allow rapid discrimination among these biotypes. These primers produce a 478-, 405-, and 303-bp mtCOI fragment for the B. New World and Q biotypes respectively. By combining these primers and using rapid PCR and electrophorotic techniques, biotype determination can be made within 3 h for up to 96 samples at a time.

Extensive arrays of pheromone traps monitor for reintroductions, but occasionally the traps collect nontarget weevils that can be misidentified by scouts. For example, the congeneric pepper weevil, Anthonomus eugenii Cano, and other superficially similar weevils are attracted to components of the boll weevil lure or trap color. Although morphologically distinguish able by trained personnel, the potential for misidentification is compounded when captured weevils are dismembered or partially consumed by ants or ground beetles that sometimes feed on them in the traps. Because misidentification can have expensive consequences, a molecular diagnostic tool would be of great value to eradication managers. We demonstrate that a cocktail of three primer pairs in a single polymerase chain reaction (PCR) amplify species-specific microsatellites that unambiguously distinguish the boll weevil from three other weevil species tested, including pepper we evil; cranberry weevil, Anthonomus eugenii musculus Say; and pecan weevil, Curculio caryae Horn. However, it does not distinguish the boll weevil from the subspecific "thurberia" weevil. A universal internal transcribed spacer primer pair included in the cocktail cross-amplifies DNA from all species, serving as a positive control. Furthermore, the diagnostic primers amplified the target microsatellites from various boll weevil adult body parts, indicating that the PCR technology using the primer cocktail is sensitive enough to positively identify a boll weevil even when the body is partly degraded.

TI Virulence Analysis of Hessian Fly Populations From Texas, Oklahoma, and Kansas SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Mayetiola destructor; Hessian fly; biotype; wheat breeding; plant resistance ID WINTER-WHEAT; CECIDOMYIIDAE; INSECTICIDES; MANAGEMENT; DIPTERA AB In recent years, the number of wheat. Triticum aestivum L., fields heavily infested by Hessian fly. Mayetiola destructor (Say), has increased in the Great Plains of the Unites States. Historically, resistance genes in wheat have been the most efficient means of controlling this insect pest. To determine which resistance genes are still effective in this area, virulence of six Hessian fly populations from Texas. Oklahoma, and Kansas was determined, using the resistance genes H3, H4, H5, H6, H7H8, H10, H11, H12, H13, H16, H17, H18, H21, H22, H23, H24, H25, H26, H31, and Hdic. Five of the tested genes, H13, H21, H25, H26, and Hdic, conferred high levels of resistance (> 80% of plants scored resistant) to all tested populations. Resistance levels for other genes varied depending on which Hessian fly population they were tested against. Biotype composition analysis of insects collected directly from wheat fields in Grayson County. TX revealed that the proportion of individuals within this population virulent to the major resistance genes was highly variable (89% for H6, 58% for H9, 28% for H5, 22% for H26, 15% for H3, 9% for H18, 4% for H21, and 0% for H13). Results also revealed that the percentages of biotypes virulent to specific resistance genes in a given population are highly correlated (r(2) = 0.97) with the percentages of susceptible plants in a virulence test. This suggests that virulence assays, which require less time and effort, cane be used to approximate biotype composition.

Doramectin serum concentration of steers receiving 600 mu g (AI)/kg body weight declined from 21.9 ppb at 0.5 wk to below detectable at 8 wk postinjection. The 1.200 mu g (AI)/kg injection resulted in serum concentrations of 29.1 ppb at 0.5 wk and declined 0.5 ppb at 8 wk postinjection. Both the 600 and 1,200 mu g (AI)/kg injections provided 100% inhibition of index of fecundity (IF) in adult lone star ticks. Amblyomma americanum L. (Acari: Ixodidae) through week 8, after which inhibition declined to 79.4 and 45.3%, respectively, during the 12th week posttreatment. For steers treated at 600 mu g (AI)/kg, mortality of adult horn flies. Hematobia irritans L. (Diptera: Muscidae), declined from 16.9% during week 2 to 3.1% during week 7 postinjection. The blood from steers treated at 1,200 mu g (AI)/kg resulted in a similar decline in mortality of blood fed adult horn flies from 29.4% during week 1 to 4.0% during week 7. The 600 mu g (AI)/kg treatment provided complete control of larval horn flies in the manure for 9 wk. whereas the 1,200 mu g (AI)/kg injection gave complete control for 14 wk posttreatment. The doramectin gel formulation provided long-lasting delivery of doramectin to cattle and extended control of lone star ticks and larval horn flies. Such a simple and inexpensive formulation could be useful in tick eradication programs by reducing the frequency of gathering cattle. C1 [Lohmeyer, K. H.; Miller, J. A.; Pound, J. M.; Klavons, J.

The level of doramectin in the serum of steers treated at 200 mu g/kg/d reached a maximum of 104.0 +/- 22.1 ppb at day 21 and declined from 93.3 +/- 20.5 ppb on the final day of treatment to below detectable by day 56. Steers treated at 50 mu g/kg/d reached a maximum level of doramectin in the serum of 24.7 +/- 1.2 ppb on day 21 and declined from 24.7 +/- 0.6 ppb on the final day of treatment to less than detectable on day 42. Both doramectin dosages provided 100% control of estimated larvae (EL) of Amblyomma americanum (L.) (Acari: Ixodidae) throughout the 28-d treatment period. Daily oral treatment with eprinomectin at a dosage of 200 mu g/kg for 28 consecutive days produced a maximum concentration in the serum of 41.6 +/- 11.0 ppb at day 14. On the final day of eprinomectin treatment, the serum concentration was 38.3 +/- 5.9 ppb. Seven days later at day 35, eprinomectin was not detectable in the serum. For steers treated at 50 mu g/kg/d for 28 consecutive days, the serum level of eprinomectin reached a maximum of 10.0 +/- 3.0 ppb on day 28 and was undetectable on day 35. Both eprinomectin dosages provided complete control of EL of A. americanum during the 28-d treatment period. Because eprinomectin is efficacious against A. americanum at lower serum levels in cattle and is eliminated from the serum at a more rapid rate than either doramectin or ivermectin, it provides advantages for use in applications such as the medicated bait for control of ticks on white-tailed deer and could have potential for use-in the Cattle Fever Tick Eradication Program.

To understand mechanisms in sensitive crops that are affected by Al stress, a proteomic analysis of primary tomato root tissue, grown in Al-amended and non-amended liquid cultures, was performed. DIGE-SDS-MALDI-TOF-TOF analysis of these tissues resulted in the identification of 49 proteins that were differentially accumulated. Dehydroascorbate reductase, glutathione reductase, and catalase enzymes associated with antioxidant activities were induced in Al-treated roots. Induced enzyme proteins associated with detoxification were mitochondrial aldehyde dehydrogenase, catechol oxidase, quinone reductase, and lactoylglutathione lyase. The germin-like (oxalate oxidase) proteins, the malate dehydrogenase, wali7 and heavy-metal associated domain-containing proteins were suppressed. VHA-ATP that encodes for the catalytic subunit A of the vacuolar ATP synthase was induced and two ATPase subunit 1 isoforms were suppressed. Several proteins in the active methyl cycle, including SAMS, quercetin 3-O-methyltransferase and AdoHcyase, were induced by Al stress. Other induced proteins were isovaleryl-CoA dehydrogenase and the GDSL-motif lipase hydrolase family protein. NADPH-dependent flavin reductase and beta-hydroxyacyl-ACP dehydratase were suppressed.

TI Inhibition of flowering in 'Arbequina' olives from chilling at lower temperatures SO JOURNAL OF FOOD AGRICULTURE & ENVIRONMENT LA English DT Article DE Chilling; flowering; freezing; inflorescence; Olea europaea L.; olive; stress AB The effect of four nighttime chilling temperatures on the induction of flowering in 'Arbequina' olives was investigated. Daytime temperature was kept at 17.5 degrees C (8 h) while nighttime temperatures (8 h) were maintained at 7.8, 4.4, 2.2 or -1.2 degrees C; transition from daytime temperatures to nighttime temperatures, and vice versa, occurred stepwise in 4 h periods. Maximal flowering occurred in trees that were given nighttime temperatures of 4.4 degrees C. Increasing nighttime chilling by lowering temperatures to 2.2 and -1.2 degrees C significantly reduced inflorescence production by 7 1 and 90%, respectively. Our results indicated no significant difference in inflorescence production in trees that were kept at nighttime temperatures of 7.8 or 4.4 degrees C. Different levels of chilling had no significant effect on number of flowers per inflorescence. Time of initiation of first inflorescence was progressively delayed with increased chilling temperatures; i.e. first inflorescence appeared after 98, 107, 124 and 131 days from the start of induction period in trees that were given nighttime temperatures of 7.8, 4.4, 2.2 or -1.2 degrees C respectively.

TI COMPARATIVE RADIATION DOSE MAPPING OF SINGLE FRUIT TYPE AND MIXED-FRUIT BOXES FOR EXPORT FROM HAWAII SO JOURNAL OF FOOD PROCESSING AND PRESERVATION LA English DT Article ID IRRADIATION QUARANTINE TREATMENTS; LEPIDOPTERA; QUALITY AB A generic radiation quarantine treatment of 400 Gy for insect pests infesting fresh fruit and vegetable and other horticultural commodities was recently approved in the U.S.A. Dose-mapping studies were conducted to compare dose variation during radiation treatment at 400 Gy of a single-fruit type and of mixed fruits packed in boxes. The tests included papaya, mango, banana, rambutan, longan, dragon fruit and various combinations of these tropical fruits. When radiation was applied to a single box containing one type of fruit or a mixture of two or three fruit types, measured doses were sometimes higher in the mixture. Irradiation of a simulated commercial load of 12 boxes resulted in no significant difference between single-fruit boxes and mixed-fruit boxes. In all experiments, the technical objectives of radiation treatment were met, meaning that all resulting doses fell between the minimum required dose of 400 Gy and the maximum allowable dose of 1,000 Gy. Quarantine treatment protocols to disinfest fresh agricultural commodities of quarantine insect pests are traditionally developed for single commodities. No postharvest quarantine treatment has ever been approved for mixed fresh commodities. The information contained herein using a generic radiation dose will be submitted to regulatory authorities to gain approval for the first disinfestation treatment for mixed fresh commodities. This could lead to export approvals for value-added mixed-fruit gift boxes or other products which would diversify revenue for the tropical fruit industry.

Reducing Salmonella Enteritidis carriage in chickens would reduce contamination of poultry meat and eggs with this pathogen. We investigated the prophylactic efficacy of feed supplemented with caprylic acid (CA), a natural, generally recognized as safe eight-carbon fatty acid, for reducing Salmonella Enteritidis colonization in chicks. One hundred commercial day-old chicks were randomly divided into five groups of 20 birds each: CA control (no Salmonella Enteritidis, CA), positive control (Salmonella Enteritidis, no CA), negative control (no Salmonella Enteritidis, no CA), and 0.7 or 1% CA. Water and feed were provided ad libitum. On day 8, birds were inoculated with 5.0 log CFU of Salmonella Enteritidis by crop gavage. Six birds from each group were euthanized on days 1, 7, and 10 after challenge, and Salmonella Enteritidis populations in the cecum, small intestine, cloaca, crop, liver, and spleen were enumerated. The study was replicated three times. CA supplementation at 0.7 and 1% consistently decreased Salmonella Enteritidis populations recovered from the treated birds. Salmonella Enteritidis counts in the tissue samples of CA-treated chicks were significantly lower (P < 0.05) than those of control birds on days 7 and 10 after challenge. Feed intake and body weight did not differ between the groups. Histological examination revealed no pathological changes in the cecum and liver of CA-supplemented birds. The results suggest that prophylactic CA supplementation through feed can reduce Salmonella Enteritidis colonization in day-old chicks and may be a useful treatment for reducing Salmonella Enteritidis carriage in chickens.

TI Inactivation of Avirulent Yersinia pestis in Butterfield's Phosphate Buffer and Frankfurters by UVC (254 nm) and Gamma Radiation SO JOURNAL OF FOOD PROTECTION LA English DT Article ID LISTERIA-MONOCYTOGENES; RESISTANCE; ENTEROCOLITICA; MEAT; TEMPERATURE; SENSITIVITY; DIACETATE; LACTATE; PLAGUE AB Yersinia pestis is the causative agent of plague. Although rare, pharyngeal plague in humans has been associated with consumption or handling of meat prepared from infected animals. The risks of contracting plague from consumption of deliberately contaminated food are currently unknown. Gamma radiation is a penetrating form of electromagnetic radiation, and UVC radiation is used for decontamination of liquids or food surfaces. Gamma radiation D(10)-values (the radiation dose needed to inactivate I log unit pathogen) were 0.23 (+/- 0.01) and 0.31 (+/- 0.03) kGy for avirulent Y. pestis inoculated into Butterfield's phosphate buffer and onto frankfurter surfaces, respectively, at 0 degrees C A UVC radiation dose of 0.25 J/cm(2) inactivated avirulent Y. pestis suspended in Butterfield's phosphate buffer. UVC radiation doses of 0.5 to 4.0 J/cm(2) inactivated 0.97 to 1.20 log units of the Y. pestis surface inoculated onto frankfurters. A low gamma radiation dose of 1.6 kGy could provide a 5-log reduction and a UVC radiation dose of I to 4 J/cm(2) would provide a I-log reduction Of Y. pestis Surface inoculated onto frankfurters. Y pestis was capable of growth on frankfurters during refrigerated storage (10 degrees C). Gamma radiation of frankfurters inhibited the growth of Y. pestis during refrigerated storage, and UVC radiation delayed the growth of Y. pestis.

TI Biological Control of Aflatoxin Contamination in Corn Using a Nontoxigenic Strain of Aspergillus flavus SO JOURNAL OF FOOD PROTECTION LA English DT Article ID UNITED-STATES; PARASITICUS; SOIL; TRANSECT; PEANUTS; FUNGI AB A 2-year Study was conducted to determine the efficacy of different applications of a nontoxigenic strain of Aspergillus flavus for reducing aflatoxin contamination in corn. Treatments consisted of the nontoxigenic strain in the form 4 (i) conidiacoated hulled barley applied to soil when corn was about 0.8 in tally (ii) conidia-coated hulled barley applied in plant whorls prior to tasseling, (iii) multiple applications of it spray formulation Of conidia during silking, and (iv) Untreated control. Treatments were replicated eight times in individual plots consisting of four rows of 18 in each. In year I. no significant differences were associated with treatments for aflatoxin, total A. flavus colonization, or incidence of nontoxigenic isolates of A. flavus i corn, which were all relatively high, ranging from 83.8 to 93.1%. In year 2, the whorl application produced a significantly lower mean aflatoxin concentration of 49.5 ppb compared with all other treatments. while both the soil (108.3 ppb) and spray applications (173.7 ppb) were significantly reduced compared with the control (191.6 ppb). The whorl application was the only treatment that had a significantly higher incidence (86.5%) of nontoxigenic isolates of A. flavus than the control had, which was still relatively high at 69.1%. Data indicated that applications of the nontoxigenic strain influenced Untreated corn, thus reducing the apparent effect of the biocontrol treatments.

Inoculated meat was cooked using the sous-vide technique, i.e., the meat was packaged in sterile bags and completely immersed in a circulating water bath at low temperature for a period of time. The bags were cooked for I It to an internal temperature of 55, 58, 60, or 62.5 degrees C, and then held from 240 min at 55 degrees C to 10 min at 62.5 degrees C. The surviving bacteria were enumerated by spiral plating onto tryptic soy agar overlaid with sorbitol-MacConkey agar. Inactivation kinetics of the pathogens deviated from first-order kinetics. D-values (time, in minutes, required for the bacteria to decrease by 90%) in the control beef ranged from 67.79 min at 55 degrees C to 2.01 min at 62.5 degrees C. D-values determined by a logistic model ranged from 36.22(D(1), the D-value of a major population of surviving cells) and 112.79 (D(2), the D-value of a minor subpopulation) at 55 degrees C to 1.39 (D(1)) and 3.00 (D(2)) at 62.5 degrees C. A significant increase (P < 0.05) in the sensitivity of the bacteria to heat was observed with the addition of 3% added antimicrobials. D-value reductions of 62 to 74% were observed with apple powder and 18 to 58% with tea powders. Thermal death times from this study will assist the retail food industry to design cooking regimes that ensure the safety of beef contaminated with E. coli O157:H7.

TI Stabilizing Oils from Smoked Pink Salmon (Oncorhynchus gorbuscha) SO JOURNAL OF FOOD SCIENCE LA English DT Article DE Alaska salmon; fish oil; fishery by-products; lipid oxidation ID POLYUNSATURATED FATTY-ACIDS; LIPID OXIDATION; LIQUID SMOKE; BY-PRODUCTS; FISH-OIL; STORAGE; FOODS AB Smoking of meats and fish is one of the earliest preservation technologies developed by humans. In this study, the smoking process was evaluated as a method for reducing oxidation of pink salmon (Oncorhynchus gorbuscha) oils and also maintaining the quality of oil in aged fish prior to oil extraction. Salmon heads that were subjected to high temperatures (95 degrees C) during smoking unexpectedly produced oils with fewer products of oxidation than their unprocessed counterparts, as measured by peroxide value (PV), thiobarbituric acid reactive substances (TBARS), and fatty acids (FA). Higher temperatures and longer smoking times resulted in correspondingly lower quantities of oxidative products in the oils. Fatty acid methyl ester (FAME) analysis of smoke-processed oils confirmed that polyunsaturated fatty acids (PUFA) were not being destroyed. Smoke-processing also imparted antioxidant potential to the extracted oils. Even when antioxidants, such as ethoxyquin or butylated hydroxytoluene, were added to raw oils, the smoke-processed oils still maintained lower levels of oxidation after 14 d of storage. However, decreased antioxidant capacity of smoke-processed oils was noted when they were heated above 75 degrees C. Vitamin studies supported the antioxidant results, with smoke-processed oils displaying higher levels of alpha-tocopherol than raw oils. Results suggest that smoking salmon prior to oil extraction can protect valuable PUFA-rich oils from oxidation. Improved preservation methods for marine oils may extend their usefulness when added as a supplement to enhance levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in foods.

Hexane-insoluble and hexane-soluble fractions were separated from 100% methanolic extract from purple rice bran (RBE-HI and RBE-HS, respectively). Total anthocyanin, tannin, flavonoid, and phenolics contents were determined in those fractions, and their antioxidant capacities were evaluated by measuring 1,1-diphenyl-2-picrylhydrazyl ( DPPH) radical scavenging capability, oxygen radical absorbance capacity (ORAC), and iron chelating capability (ICC). RBE-HI and RBE-HS were also added to restructured patties made from minced channel catfish (Ictalurus punctatus) belly flap meat. Lipid oxidation, color, and/or textural properties were determined for raw and cooked patties during a 12-d storage at 4 degrees C. All antioxidant indices, except for ICC, of RBE-HI were significantly higher than those of RBE-HS due probably to its higher anthocyanin content (P < 0.05). RBE-HS showed higher ICC (P < 0.05). However, both fractions showed similar antioxidant activity in raw and cooked patties during storage, resulting from the complexity of antioxidant action in food systems. Textural properties (hardness, cohesiveness, chewiness, and springiness) in cooked patties with RBE-HS and RBE-HI were well maintained during storage, but changed significantly in the control (P < 0.05). Only RBE-HS limited microbial growth in raw patties during storage (P < 0.05), but its inhibitory effect was marginal because of low-dose and physical interactions with the matrix. L* (lightness) and a* (redness) of raw and cooked patties decreased significantly by both fractions, whereas b* (yellowness) was significantly decreased by RBE-HI and increased by RBE-HS (P < 0.05). In conclusion, we suggest that purple rice bran extract is applicable to meat products as a natural preservative, but color change in the products may limit its application. C1 [Green, B.

TI Detection of Fecal Residue on Poultry Carcasses by Laser-Induced Fluorescence Imaging SO JOURNAL OF FOOD SCIENCE LA English DT Article DE fecal residues; fluorescence imaging; food safety; laser induced; poultry carcasses ID CONTAMINANTS; EXCITATION; SYSTEM AB Feasibility of fluorescence imaging technique for the detection of diluted fecal matters from various parts of the digestive tract, including colon, ceca, small intestine, and duodenum, on poultry carcasses was investigated. One of the challenges for using fluorescence imaging for inspection of agricultural material is the low fluorescence yield in that fluorescence can be masked by ambient light. A laser-induced fluorescence imaging system (LIFIS) developed by our group allowed acquisition of fluorescence from feces-contaminated poultry carcasses in ambient light. Fluorescence emission images at 630 nm were captured with 415-nm laser excitation. Image processing algorithms including threshold and image erosion were used to identify fecal spots diluted up to 1: 10 by weight with double distilled water. Feces spots on the carcasses, without dilution and up to 1: 5 dilutions, could be detected with 100% accuracy regardless of feces type. Detection accuracy for fecal matters diluted up to 1: 10 was 96.6%. The results demonstrated good potential of the LIFIS for detection of diluted poultry fecal matter, which can harbor pathogens, on poultry carcasses.

The objectives of this study were to model the growth characteristics and examine the growth relationship of L. monocytogenes and native microflora in smoked salmon. Smoked salmon samples with a native microflora count of 2.9 log(10) CFU/g were inoculated with a 6-strain mixture of L. monocytogenes to levels of log(10) 1.6 and log(10) 2.8 CFU/g, and stored at 4, 8, 12, and 16 degrees C. Growth characteristics (lag phase duration [LPD, h], growth rate [GR, log(10) CFU/h], and maximum population density [MPD, log(10) CFU/g]) of L. monocytogenes and native microflora were determined. At 4 to 16. C, the LPD, GR, and MPD were 254 to 35 h, 0.0109 to 0.0538 log(10) CFU/h, and 4.9 to 6.9 log(10) CFU/g for L. monocytogenes, respectively, and were 257 to 29 h, 0.0102 to 0.0565 log(10) CFU/h, and 8.5 to 8.8 log(10) CFU/g for native microflora. The growth characteristics of L. monocytogenes or the native microflora were not significantly different (P > 0.05), regardless the initial levels of L. monocytogenes. Mathematical equations were developed to describe the LPD, GR, and MPD of L. monocytogenes and native microflora as a function of storage temperature. The growth relationship between L. monocytogenes and native microflora was modeled and showed that the LPD and GR of L. monocytogenes were similar to those of native microflora. These models can be used to estimate the growth characteristics of L. monocytogenes in smoked salmon, and thereby enhance the microbiological safety of the product.

Twenty-seven sporulation- and germination-related genes were selected for the target genes. Our results demonstrated that gene expression levels were altered by heat and microfiltration whereas the pasteurization and pasteurization and microfiltration resulted in less alteration of gene expression. Heat activated and inhibited both sporulation- and germination-related genes, suggesting that bacterial spores underwent different molecular mechanism for heat treatments. Our results may provide some insight into the molecular mechanisms of spore survival in response to heat treatment and different intervention strategies used to treat fluid skim milk.

Flash (Steam) Pasteurization (FP) and ultraviolet light (254 nm-UVC) has been shown to reduce levels of L. monocytogenes and L. innocua on frankfurters. In this study, the use of UVC light followed by FP to inactivate L. innocua, a nonpathogenic surrogate for L. monocytogenes, on frankfurters that contained sodium diacetate and potassium lactate (SDA/PL) in a pilot-plant setting was investigated. Application of UVC (1.0 J/cm(2)), followed by FP (0.75 s steam/121 degrees C) resulted in inactivation of 3.19 log L. innocua, while application of UVC (4.0 J/cm(2)), followed by FP (3 s steam/121 degrees C) resulted in inactivation of 3.89 log of L. innocua. A refrigerated storage study (8 degrees C) of frankfurters that contained SDA/PL that were treated with UVC followed by FP revealed the growth of L. innocua was inhibited for approximately 8 wk following application of the interventions. The use of UVC in combination with FP had little effect on frankfurter color and texture. The combination of UVC, FP, and SDA/PL was found to be an effective hurdle process for decontamination of frankfurter surfaces. C1 [Sommers, C. H.; Geveke, D.

TI Ultraviolet Light (254 nm) Inactivation of Listeria monocytogenes on Frankfurters That Contain Potassium Lactate and Sodium Diacetate SO JOURNAL OF FOOD SCIENCE LA English DT Article DE frankfurters; Listeria monocytogenes; ultraviolet light ID MEAT; RADIATION; IRRADIATION; PATHOGENS; REPAIR; RISK AB Listeria monocytogenes, a psychrotrophic foodborne pathogen, is an occasional postprocess contaminant on ready-to-eat meat (RTE) products including frankfurters. Ultraviolet C light (UVC) is an FDA-approved technology for the decontamination of food surfaces. In this study, the ability of UVC to inactivate L. monocytogenes on frankfurters that contained potassium lactate (PL) and sodium diacetate (SDA), either before or after packaging, was investigated. UVC irradiation of frankfurters that were surface-inoculated with L. monocytogenes resulted in a 1.31, 1.49, and 1.93 log reduction at doses of 1, 2, and 4 J/cm(2), respectively. UVC treatment had no effect on frankfurter color or texture at UVC doses up to 4 J/cm(2). Frankfurter meat treated with UVC doses up to 16 J/cm(2) did not increase mutagenesis in bacterial or human cells, either with or without exogenous metabolic activation. UVC treatment of single-layer frankfurter packs at a dose of 2 J/cm(2) resulted in a 0.97 (+/- 0.14) log reduction of L. monocytogenes. Following 8 wk of refrigerated storage L. monocytogenes levels decreased by only 0.65 log in non-UVC-treated frankfurter packs compared with 2.5 log in the UVC-treated packs. Because the numbers of L. monocytogenes associated with contaminations of ready-to-eat meats are typically very low, the use of UVC in combination with potassium lactate and sodium diacetate has the potential to reduce the number of frankfurter recalls and foodborne illness outbreaks.

TI Landowner Awareness and Adoption of Wildfire Programs in the Southern United States SO JOURNAL OF FORESTRY LA English DT Article DE wildfire; nonindustrial private forestland (NIPF) owners; race; gender ID NATIONAL-SURVEY; POLICY; FIRE AB We surveyed nonindustrial private (family) forestland owners in five states in the southern United States to identify their perception, awareness, and adoption of wildfire prevention and mitigation programs. Wildfire is peracived as an imminent threat by the majority of the survey respondents, and over two-thirds of them have taken some preventive measure. Program awareness, wildfire experience and risk perception, information sources, wildfire preventive activities, and preferences for government interventions differ across racial groups; experience with wildfire, knowledge and activities of fire protection, information sources, and desire for government intervention and technical assistance are also significantly different between male and female landowners. Additionally, program awareness by landowners does, not necessarily translate into action in preventing and mitigating wildfire, suggesting that additional assistance and stimuli would be needed to encourage private landowners to be more proactive against wildfire.

In response, Brazil reformed its federal forest laws in 2006, creating new regulatory, development, and incentive policy instruments and institutions. Federal forestry responsibilities are maintained within the ministry of the environment; its regulatory agency responsibilities are divided among three different branches of the agency; many powers are delegated to states and municipalities; and a new private concession system is being developed. These reforms offer promise to improve forest protection and management in Brazil but must overcome significant institutional and social resistance for success.

We investigated the ability of purified strawberry fractions to induce apoptotic cell death in pre-B acute lymphoblastic leukemia (ALL) lines, including lines derived from patients with high-risk B-ALL carrying the t(4;11)(q21;q23) chromosomal translocation. The isolated strawberry constituents were first screened for their anti-cancer activity using a 24 h fluorescence microplate method for detecting mitochondrial membrane depolarization. Active samples were further investigated for induction of apoptosis after addition of multiple doses to the leukemia cells over a period of 72 h. Quercetin, kaempferol, and ellagic acid induced significant apoptosis in the three cancer cell lines, as measured by loss of nuclear DNA, loss of mitochondrial membrane potential, and activation of caspase-3. Our data show that constituents of strawberries induce apoptosis in high-risk leukemia cells and may have potential in the prevention or treatment of this disease. (C) 2009 Elsevier Ltd.

Chemical characterization of the sample by X-ray fluorescence spectroscopy revealed a high amount of toxic heavy metals such as Cu, Cr, Pb, Ni, and Zn. Molecular community structures were determined by phylogenetic analysis of 16S rRNA gene sequences retrieved from enrichment cultures growing in presence of microcrystalline cellulose as the sole source of carbon. All phylotypes retrieved from enrichment cultures were affiliated to Firmicutes. Cellulose-degrading mesophilic and thermophilic pure cultures belonging to the genera Brevibacillus, Paenibacillus, Bacillus, and Geobacillus were isolated from enrichment cultures, and selected cultures were studied for enzyme activities. For a mesophilic isolate (DUSELG12), the optimum pH and temperature for carboxymethyl cellulase (CMCase) were 5.5 and 55A degrees C, while for a thermophilic isolate (DUSELR7) they were 5.0 and 75A degrees C, respectively. Furthermore, DUSELG12 retained about 40% CMCase activity after incubation at 60A degrees C for 8 h. Most remarkably, thermophilic isolate, DUSELR7 retained 26% CMCase activity at 60A degrees C up to a period of 300 h. Overall, the present work revealed the presence of different cellulose-degrading bacterial lineages in the unique deep subsurface environment of the mine. The results also have strong implications for biological conversion of cellulosic agricultural and forestry wastes to commodity chemicals including sugars.

Male A. suspensa where submitted to four different treatments: (M(+)P(+)) application of juvenile hormone analog, methoprene (M) and sugar and hydrolyzed yeast as adult food; (M(+)P(-)) application of M and sugar as adult food; (M(-)P(+)) no application of M and sugar and hydrolyzed yeast as adult food; and (M(-)P(-)) no application of M and sugar as adult food. M(+)P(+) males initiated and participated more in aggregations, mated more frequently, and occupied the lek centers more often. They also had fewer unsuccessful mounting attempts than males in all the other treatments. M(+)P(+) males also emitted pheromones and acoustically signaled more often and attracted more females than males in other treatments. Male sexual performance was improved due to methoprene, protein supply,and the interaction of methoprene and protein for most of the parameters. Since the success of the sterile insect technique (SIT), a commonly employed technique to control pest tephritids, requires the release of males that can form leks, engage in agonistic sexual interactions, and attract females, these positive effects of protein and methoprene may substantially improve SIT programs.

Exposure to elevated O(3) typically results in suppressed photosynthesis, accelerated senescence, decreased growth and lower yields. Various approaches used to evaluate O(3) effects generally concur that current yield losses range from 5% to 15% among sensitive plants. There is, however, considerable genetic variability in plant responses to O(3). To illustrate this, we show that ambient O(3) concentrations in the eastern United States cause substantially different levels of damage to otherwise similar snap bean cultivars. Largely undesirable effects of O(3) can also occur in seed and fruit chemistry as well as in forage nutritive value, with consequences for animal production. Ozone may alter herbicide efficacy and foster establishment of some invasive species. We conclude that current and projected levels of O(3) in many regions worldwide are toxic to sensitive plants of agricultural and horticultural significance. Plant breeding that incorporates O(3) sensitivity into selection strategies will be increasingly necessary to achieve sustainable production with changing atmospheric composition, while reductions in O(3) precursor emissions will likely benefit world food production and reduce atmospheric concentrations of an important greenhouse gas.

TI Transmission of MdSGHV among adult house flies, Musca domestica (Diptera: Muscidae), occurs via oral secretions and excreta SO JOURNAL OF INVERTEBRATE PATHOLOGY LA English DT Article DE Musca domestica; House fly; MdSGHV; Insect virus; Oral transmission ID SALIVARY-GLAND HYPERTROPHY; ORYCTES VIRUS; INFECTION; SUSCEPTIBILITY; BEETLE AB The MdSGHV is a double-stranded DNA virus that replicates in the salivary glands of infected adult house flies. Transmission of this non-occluded, enveloped virus is believed to be mediated orally via deposition and consumption of oral secretions composed of salivary gland secretions and crop contents. In this study, transmission electron micrographs of crops from infected flies showed numerous enveloped virions in the crop lumen adjacent to the Cuticular intima, as well as on the hemocoel side in close vicinity to muscle cells. Oral treatments of newly emerged flies with viremic salivary gland homogenates, crop homogenates. or gradient-purified virus resulted in an average 44% infection. Virus released via oral secretion was infectious when ingested by newly emerged adult flies, resulting in an average 66% infection. Using quantitative real-time PCR, MdSGHV DNA was quantified in oral secretions and excreta obtained from viremic flies. Between 2 and 4 days post-infection (dpi), viral copy numbers in oral secretions increased exponentially and from 5 to 21 dpi each infected fly released an average 106 MdSGHV copies per feeding event. Excreta samples collected overnight from individual infected flies at 5 dpi contained an average 6.5 x 10(5) viral copies. Low but detectable infection rates were produced when newly emerged flies were challenged with excreta samples. In summary, evaluation of the quantity and infectivity of MdSGHV released by individual infected house flies clearly showed that deposition of oral secretions and excreta onto a shared food substrate is the main route of natural MdSGHV transmission among adult house flies.

Measurements were performed in participants (n = 135) at baseline and after 6 weeks on either rosuvastatin (40 mg/day) or atorvastatin (80 mg/day) therapy. Plasma sterols were measured using gas-liquid chromatography. Rosuvastatin and atorvastatin significantly (P < 0.001) altered plasma total cholesterol (C) levels by -40%, and the ratios of lathosterol/C by -64% and -68%, and campesterol/C by +52% and +72%, respectively, with significant differences (P < 0.001) between the treatment groups for the latter parameter. When using absolute values of these markers, subjects with the greatest reductions in both synthesis (lathosterol) and absorption (campesterol) had significantly greater reductions in total C than subjects in whom the converse was true (-46% versus -34%, P = 0.001), with similar effects for LDL-C. Rosuvastatin and atorvastatin decreased markers of cholesterol synthesis and increased markers of fractional cholesterol absorption, with rosuvastatin having significantly less effect on the latter parameter than atorvastatin. In addition, alterations in absolute values of plasma sterols correlated with the cholesterol lowering response.-van Himbergen, T. M., N. R. Matthan, N. A. Resteghini, S. Otokozawa, M. Ai, E. A.

Despite biological plausibility, for the most part, data derived from nutrient supplement trials using moderate to high doses of single nutrients or nutrient combinations (exceeding amounts to avoid nutrient deficiency) have been disappointing. The data for vitamin D is not yet adequate to evaluate; observational data suggest were a relationship to exist it would be related to nutrient insufficiency. There is some evidence that use of nutrient supplements intended to decrease CVD risk has resulted in unanticipated adverse consequences. Potential discrepancies between observational and interventional data include concerns of residual confounding by diet and lifestyle patterns, publication bias against studies with null or negative outcomes, reliance on secondary rather than primary prevention trials, and unaccounted for contribution of genotypic variations. At this time there are insufficient data to recommend the routine use of nutrient supplements to prevent or treat CVD. In the recent past we have learned a great deal about anticipated and unanticipated consequences of nutrient supplementation and cardiovascular outcomes. As a result, we are in a better position to adjudicate new potential relationships as data emerge.-Lichtenstein, A. H. Nutrient supplements and cardiovascular disease: a heartbreaking story. J.

We tested the hypothesis that female and male ruminants select habitats that differ with respect to quality and abundance of forage by evaluating sex-specific responses of North American elk (Cervus elaphus) to an experimental fuels-reduction program at the Starkey Experimental Forest and Range (Starkey) in northeastern Oregon. From 2001 to 2003, 26 stands of true fir (Abies) and Douglas-fir (Pseudotsuga menziesii) were mechanically thinned and burned, whereas 27 similar stands were left untreated to serve as controls. We used measured differences in forage quality and quantity to predict :;ex-specific responses to this habitat manipulation. We compared seasonal patterns of habitat selection between the sexes using locations from 48 female and 14 male elk collected during daily periods of peak foraging activity during spring and summer of 2005 and 2006. During spring, females selected 4-year-old burns and used 2- and 3-year-old burns in proportion to their availability, whereas males avoided all fire-treated stands. In addition, control stands were avoided by females but selected by males during spring. During summer, control stands were selected and treatment stands either were avoided or used in proportion to their availability by the sexes. Use of treated stands by female and male elk was influenced by different environmental variables across seasons, but mean overlap of utilization distributions between the sexes was higher in Summer than spring. These results indicate that although fuels-reduction treatments at Starkey may have increased foraging opportunities for female elk in spring, those treatments likely were of little benefit to male elk.

TI Development of a culture independent method to characterize the chemotactic response of Flavobacterium columnare to fish mucus SO JOURNAL OF MICROBIOLOGICAL METHODS LA English DT Article DE Chemotaxis; Fish mucus; Flavobacterium columnare ID CHANNEL CATFISH AB Flavobacterium columnare, the causative agent of columnaris disease, is a significant pathogen of many freshwater fish species worldwide and is considered one of the most important pathogens impacting the channel catfish (Ictalurus punctatus Rafinesque) industry in the United States. Recent research has demonstrated that F. columnare exhibits a chemotactic response to mucus from the skin of catfish and this response may be important for pathogenesis. In this study, a culture independent method was developed to quantify the chemotactic response of F. columnare to skin mucus. The method employs the use of blind-well chemotaxis chambers which overcomes difficulties using the traditional capillary tube assay and uses a cell proliferation assay to quantify viable cells which reduces the time and labor associated with culturing the bacterium. Application of the method to two sets of catfish skin mucus samples demonstrated that there is variation in the chemotactic response of F. columnare to individual catfish mucus samples, and similar results were obtained to previously published research using the traditional capillary tube method. The use of this method will enhance the ability to further characterize the chemotactic response of F. columnare to catfish skin mucus in order to increase the understanding of this important host-pathogen interaction.

Decreased immunoreactivity for IGFBP2 was observed in the cerebral cortex, hippocampus and brainstem of SOD1(G93A) transgenic mice. In the cerebral cortex, the number of IGFBP2-positive cells was decreased in the somatomotor area, somatosensory area, auditory area, visual area, entorhinal area, piriform area and prefrontal area. In the hippocampal formation, IGFBP2 immunoreactivity was significantly decreased in the CA1-3 areas and the dentate gyrus. In the brainstem, few IGFBP2-immunoreactive cells were observed in the medullary and pontine reticular formation, vestibular nucleus, trigeminal motor nucleus, facial nucleus, hypoglossal nucleus and raphe nucleus. In the spinal cord, IGFBP2 immunoreactivity was not significantly decreased in SOD1(G93A) transgenic mice. This study showing decreased IGFBP2 in different brain regions of SOD1(G93A) transgenic mice may provide clues for understanding differential susceptibility of neural structures in ALS.

With longer insertion times, bimetals registered 25-81% and digitals registered 14-92% of the products as cooked. Bimetals averaged 1-9F and the digitals averaged 2-7F less than the thermocouples. Measurement repeatability (precision) was high within and between individual thermometers of the same model. Results indicate that the consumer thermometers evaluated in this study required more than the recommended time to register products as cooked. C1 [Liu, M. N.; Callahan, J. A.; Solomon, M.

TI ACCURACY, PRECISION AND RESPONSE TIME OF CONSUMER FORK, REMOTE, DIGITAL PROBE AND DISPOSABLE INDICATOR THERMOMETERS FOR COOKED GROUND BEEF PATTIES AND CHICKEN BREASTS SO JOURNAL OF MUSCLE FOODS LA English DT Article AB Nine different commercially available instant-read consumer thermometers (forks, remotes, digital probe and disposable color change indicators) were tested for accuracy and precision compared with a calibrated thermocouple in 80 and 90% lean ground beef patties and boneless and bone-in chicken breasts cooked on gas grills, electric griddles and baked in consumer ovens. All models registered less than 42% of the products as cooked at the recommended insertion time except for one indicator model which registered greater than 50% of the products as cooked in five meat product/cooking method combinations. Average thermometer readings deviated from the thermocouple by as much as 64F. Increasing insertion time increased percentage of product registering as cooked and decreased the temperature difference. Measurement repeatability (precision) was high within and between individual thermometers of the same model. These results indicate that consumers using these thermometers would cook meat products to higher temperatures than necessary to destroy harmful microorganisms. C1 [Liu, M. N.; Callahan, I.

TI CONTROL OF LISTERIA MONOCYTOGENES ON FRANKFURTERS WITH ANTIMICROBIALS AND HYDRODYNAMIC PRESSURE PROCESSING SO JOURNAL OF MUSCLE FOODS LA English DT Article ID SODIUM LACTATE; MEAT; NISIN; ACID; SALMONELLA; PEDIOCIN; BOLOGNA; 4-DEGREES-C; INHIBITION; TENDERNESS AB The antilisterial activity of sodium diacetate and pediocin (ALTA 2341) on frankfurters was evaluated in combination with hydrodynamic pressure processing (HDP). Minimum inhibitory concentration (MIC) of these strains as determined in tryptic soy broth was 0.4% and > 600 AU/mL, for sodium diacetate and ALTA 2341, respectively. Frankfurters were surface inoculated with a five-strain mixture of Listeria monocytogenes after dipping in (1) control (sterile water); (2) 5% sodium diacetate; (3) 3% ALTA 2341(P1); (4) 6% ALTA 2341 (P2); (5) P1 + sodium diacetate; and (6) P2 + sodium diacetate for 5 min. The frankfurters were vacuum-packaged and treated with hydrodynamic pressure or without HDP. Frankfurters were analyzed at 0, 7, 14 and 28 d for pH, L. monocytogenes (MOX) and aerobic (TSAYE) cell populations during storage at 4C. Antimicrobials and HDP treatment did not change (P < 0.05) the frankfurter pH. HDP treatment significantly reduced (1 log(10) cfu/g) L. monocytogenes populations in frankfurters. Dipping treatments containing sodium diacetate or ALTA 2341 did not significantly reduce L. monocytogenes in frankfurters. There was a no synergistic effect between ALTA 2341 and HDP for inhibition of L. monocytogenes. The reduction pattern in aerobic cell populations during storage of antimicrobials and HDP-treated frankfurters was similar to that of L. monocytogenes reduction. These results indicate that the ALTA 2341 preparation was not efficient enough to kill L. monocytogenes. Other antimicrobials should be evaluated in conjunction with HDP treatment for synergistic inhibition of L. monocytogenes during storage at 4C. C1 [Patel, J. R.; Sanglay, G. C.; Solomon, M.

By taking into account the Boltzmann distribution of conformers, the combined RMSDs between experimental and calculated H-1 and C-13 NMR shifts were able to determine the correct isomer, especially when only aliphatic nuclei were used. The calculated relative energies and interproton distances were also consistent with chemical isomerization experiments and NOE-based interproton distance calculations. Complementary to the NOE-based method, a comparison between experimental and calculated NMR chemical shifts can provide an efficient method to assign the relative configuration of natural products.

TI Mucosal Maltase-Glucoamylase Plays a Crucial Role in Starch Digestion and Prandial Glucose Homeostasis of Mice SO JOURNAL OF NUTRITION LA English DT Article ID NATIVE CEREAL STARCHES; PROPERTY; GLUCONEOGENESIS; MOUSE AB Starch is the major source of food glucose and its digestion requires small intestinal alpha-glucosidic activities provided by the 2 soluble amylases and 4 enzymes hound to the mucosal surface of enterocytes. Two of these mucosal activities are associated with sucrase-isomaltase complex, while another 2 are named maltase-glucoamylase (Mgam) in Mice. Because the role of Mgam in alpha-glucogenic digestion of starch is not well understood, the Mgam gene was ablated in mice to determine its role in the digestion of diets with a high content of normal coin stanch (CS) and resulting glucose homeostasis Four days of unrestricted ingestion of CS increased intestinal alpha-glucosidic activities in wild-type (WT) mice but did riot affect the activities of Mgam-null mice. The blood glucose responses to CS ingestion did riot differ between null and WT Mice, however, insulinemic responses elicited in WT mice by CS consumption were undetectable in null mice. Studies of the metabolic route followed by glucose derived from intestinal digestion of (13)C-labeled and amylase-predigested algal starch performed by gastric infusion showed that, in null mice, the capacity for starch digestion and its contribution to blood glucose was reduced by 40% compared with WT mice. The reduced alpha-glucogenesis of null mice was most probably compensated for by increased hepatic gluconeogenesis, Maintaining prandial glucose concentration and total flux at levels comparable to those of WT mice. In conclusion, mucosal alpha-glucogenic activity of Mgam plays a crucial role in the regulation of prandial glucose homeostasis. J. Nutr. 139: 684-690, 2009.

Infectious diseases such as malaria pose an additional risk. We examined the cross-sectional relationships among malaria infection, hemoglobin (Hb) concentration, length-for-age Z-scores (LAZ), motor activity, behavior, and motor and language development in 841 Zanzibari children 5-19 mo old. We used structural equation modeling to test the fit of the data to a theoretical model and to examine the relationships among the variables in 3 age groups (5-9, 10-14, and 15-19 mo). The model fit the data for all age groups. In the youngest and oldest groups, children with higher malaria parasite densities had significantly lower Hb and LAZ. Higher LAZ significantly predicted higher total motor activity, and motor and language development scores in all age groups. In the oldest group, children who had higher Hb had higher motor development and activity scores. Malaria was directly and indirectly related to motor activity in the 10- to 14-mo-old group [standardized total effects, -0.14; direct, -0.10 (P=0.015); and indirect, -0.0381. The significant fit of the models to the data and the statistical significance of many of the specific pathways highlight the complexities of the relationships between health and nutrition and child development outcomes in this population. In addition, the results suggest that multiple interventions are likely necessary to improve child development outcomes in this population of nutritionally at-risk children and that the potential effectiveness of interventions may differ according to age (i.e. prevention and treatment of anemia, stunting, and malaria).

In 2002, the Institute of Medicine Concluded that insufficient data wore available to define Dietary Reference Intakes {DRI} for eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), noting only that EPA and DHA could contribute tip to 10% toward meeting the Adequate Intake for alpha-linolenic acid. Since then, substantial new evidence has emerged supporting the need to reassess this recommendation. Therefore, the Technical Committee on Dietary Lipids of the International Life Science, Institute North America sponsored a workshop on 4-5 June 2008 to consider whether the body of evidence specific to the major chronic diseases in the United Stales-coronary heart disease (CHD), cancel, and cognitive decline-had evolved sufficiently to justify reconsideration of DRI for EPA+DHA. The workshop participants arrived at these conclusions: 7) consistent evidence from multiple research paradigms demonstrates a clear, inverse relation between EPA+DHA intake and risk of fatal (and possibly nonfatal) CHID, providing evidence that supports a nutritionally achievable DRI for EPA+DHA between 250 and 500 mg/d; 2) because of the demonstrated low conversion from dietary ALA, protective tissue levels of EPA+DHA car be achieved only through direct consumption of these fatty acids, 3) evidence of beneficial effects of EPA + DHA on cognitive decline are emerging but are riot yet sufficient to support an Intake level different from that needed to achieve CHD risk reduction; 4) EPA+DHA do not appear to reduce risk for cancer, and 5) there is no evidence that intakes of EPA + DHA in these recommended ranges are harmful..

TI Copper deficiency inhibits Ca2+-induced swelling in rat cardiac mitochondria SO JOURNAL OF NUTRITIONAL BIOCHEMISTRY LA English DT Article DE Copper deficiency; Heart; Mitochondria; Permeability transition pore; Cytochrome c oxidase; Rats ID PERMEABILITY TRANSITION PORE; CYTOCHROME-C-OXIDASE; HIGH-CONDUCTANCE STATE; CELL-DEATH; OXIDATIVE STRESS; COMPLEX-I; CALCIUM MOBILIZATION; ELECTRON-TRANSPORT; REACTIVE OXYGEN; FREE-RADICALS AB Cu deficiency disrupts the architecture of mitochondria, impairs respiration, and inhibits the activity of cytochrome c oxidase - the terminal, Cu-dependent respiratory complex (Complex IV) of the electron transport chain. This suggests that perturbations in the respiratory chain may contribute to the changes in mitochondrial structure caused by Cu deficiency. This study investigates the effect of Cu deficiency on Ca2+-induced mitochondrial swelling as it relates to changes in respiratory complex activities in cardiac mitochondria of rats. Male weanling rats were fed diets containing either no added Cu (Cu0), 1.5 mg Cu/kg (Cu1.5), 3 mg Cu/kg (Cu3) or 6 mg Cu/kg (Cu6). The rate of Ca2+-induced mitochondrial swelling in the presence of succinate and oligomycin was reduced, and the time to reach maximal swelling was increased only in the rats consuming Cu0 diet. Cytochrome c oxidase activity was reduced 60% and 30% in rats fed Cu0 and Cu1.5, respectively, while NADH:cytochrome c reductase (Complex I + ComplexIII) activity was reduced 30% in rats consuming both Cu0 and Cu1.5. Mitochondrial swelling is representative of mitochondrial permeability transition pore (MPTP) formation and the results suggest that Ca2+-induced MPTP formation occurs in cardiac mitochondria of Cu-deficient rats only when cytochrome c oxidase activity falls below 30% of normal. Decreased respiratory complex activities caused by severe Cu deficiency may inhibit MPTP formation by increasing matrix ADP concentration or promoting oxidative modifications that reduce the sensitivity of the calcium trigger for MPTP formation.

TI Association of Sequence Variations in Vitamin K Epoxide Reductase and gamma-Glutamyl Carboxylase Genes with Biochemical Measures of Vitamin K Status SO JOURNAL OF NUTRITIONAL SCIENCE AND VITAMINOLOGY LA English DT Article DE vitamin K epoxide reductase; gamma glutamyl carboxylase; vitamin K; warfarin; polymorphism ID WARFARIN DOSE REQUIREMENTS; DEPENDENT CARBOXYLASE; INTERINDIVIDUAL VARIABILITY; CYTOCHROME P4502C9; VKORC1 HAPLOTYPES; APOE GENOTYPE; SENSITIVITY; PLASMA; CYP2C9; BONE AB Genetic factors, specifically the VKORC1 and GGCX genes, have been shown to contribute to the interindividual variability in response to the vitamin K-antagonist, warfarin, which influences the dose required to achieve the desired anticoagulation response. These differences in warfarin sensitivity may be explained by differences in vitamin K status. Men and women (n=416. 60-80 y), primarily of European descent, were genotyped for common polymorphism in VKORC1 and GGCX. Cross-sectional associations exist between polymorphisms and biochemical markers of vitamin K [plasma phylloquinone, percent undercarboxylated osteocalcin (%ucOC)]. VKORC1 rs8050894 GG homozygotes had significantly higher cross-sectional measures of plasma phylloquinone than carriers of the CG or CC genotypes (plasma phylloquinone geometric means: GG 0.874 +/- 0.092 versus CG/CC 0.598 +/- 0.044; p=0.020), whereas carriers of VKORC1 rs7294 AA or AG had significantly lower plasma phylloquinone concentrations compared to GG homozygotes (plasma phylloquinone geometric means: 0.579 +/- 0.045 versus 0.762 +/- 0.057; p=0.035).

TI SEROEPIDEMIOLOGY OF TOXOPLASMA GONDII INFECTION IN PREGNANT WOMEN IN RURAL DURANGO, MEXICO SO JOURNAL OF PARASITOLOGY LA English DT Article AB The epidemiology of Toxoplasma gondii infection in pregnant women in rural Mexico is largely unknown. the sero-epidemiology of T. gondii infection in 439 pregnant women from 9 communities in rural Durango State, Mexico was investigated. Using commercial enzyme-linked immunoassays, scra were tested for T. gondii IgG, IgM, and avidity antibodies. Prevalences of T. gondii IgG antibodies in the communities varied from 0% to 20%. Overall. 36 (8.2%) of the 439 women had IgG T. gondii antibodies. Ten (2.3%) women had also T. gondii IgM antibodies: IgG avidity was high in all IgM-positive women, suggesting chronic infection. None of the women, however, had delivered a known T. gondii-infected child. The seroprevalence was significantly higher (P < 0.05) in women from low socio-economic conditions (14%) than in those with higher socio-economic status (6.6%). Multivariate analysis showed that T. gondii infection was associated with soil floors at home (adjusted OR = 2.89; 95% CI: 1.12-7.49). This is the first epidemiological study of T. gondii infection in pregnant women in rural Mexico. C1 [Alvarado-Esquivel, C.; Torres-Castorena, A.; Liesenfeld, O.; Garcia-Lopez, C.

TI ISOLATION OF TOXOPLASMA GONDII FROM ANIMALS IN DURANGO, MEXICO SO JOURNAL OF PARASITOLOGY LA English DT Article ID FREE-RANGE CHICKENS; GENETIC-CHARACTERIZATION; PREVALENCE; DOGS; ANTIBODIES; CATS; INFECTION; AMERICA; BRAZIL; STATE AB Little is known concerning the epidemiology of Toxoplasma gondii infection in people and animal in rural Mexico. Serum samples and tissues from 150 dogs (Canis familaris), 150 cats (Felis catus). 65 opossums (Didelphis virginianus). 249 rats (Rattus spp.). 127 mice (Mus musculus), and 69 squirrels (Spermophilus variegatus) from the Durango area were evaluated for T. gondii infection. Using a modified agglutination test and a serum dilution of 1:25, antibodies to this parasite were found in 68 (45.3%) of 150 dogs. 14 (9.3%) of 150 cats, 11 (16.6%) of 66 opossums, 2 (0.8%) of 249 rats, 4 (3.1%) of 127 mice, and 0 of 69 squirrels. Tissues (brain and heart) of dogs, cats, opossums, rats, mice, and squirrels were bioassayed in mice for the presence of T. gondii. Viable T. gondii was isolated in tissues from 3 of 28 seropositive dogs and 5 of 8 seropositive cats, but not from the other animals. The DNA obtained from the 3 T. gondii isolates from dogs, 6 isolates from 5 cats, and 4 isolates from free-range chickens from Mexico, previously isolate, were genotyped. The PCR-RFLP typing, which used 11 markers (B1, SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358. PKI, and Apico), identified 5 genotypes. One genotype (the 4 chicken isolates) belongs to the clonal Type III lineage, three genotypes were reported in previous reports, and 1 genotype is unique. C1 [Dubey, J. P.; Velmurugan, G.

Anti-bodies to toxoplasma gondii were assayed in the sera of 143 goats from 3 Brazilian states, using modified agglutination test (MAT titer >= 1:25); 46 (32.2%) tested positive. Samples of brain, heart, diaphragm, and masseter of seropositive animals were pooled, digested in pepsin, and bioassayed in mice. Viable T. gondii specimens were isolated from tissue homogenates of 12 goats; the isolates were designated TgGtBr1-12. Ten of the 12 isolates killed 100% of infected mice, indicating that goats can harbor mouse-virulent T. gondii and, hence, can serve as a source of infection for humans. C1 [Ragozo, A. M. A.; Yai, L.

Laboratory mice fed these oocysts developed antibodies to T. gondii in their sera and T. gondii tissue cysts in their brains. The DNA extracted from the brains of infected mice was characterized using 10 polymerase chain reaction-restricted fragment length polymorphic markers (SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico). The isolate designated TgRsCr1 was found to be non-clonal with Type I, II, and III alleles at different loci. This is the first isolation of T. gondii from this host. C1 [Dubey, J. P.; Velmurugan, G.

TI Why Museums Matter: A Tale of Pinworms (Oxyuroidea: Heteroxynematidae) Among Pikas (Ochotona princeps and O. collaris) in the American West SO JOURNAL OF PARASITOLOGY LA English DT Article ID GLOBAL CLIMATE-CHANGE; NORTH-AMERICA; PARASITES; NEMATODA; LAGOMORPHA; OXYURIDAE; DIVERSIFICATION; BIOGEOGRAPHY; QUATERNARY; RICHARDSON AB Permanent and well-supported museum or natural history collections provide a solid foundation for the process of systematics research through creation of an empirical record which validates our understanding of the biosphere. We explore the role of museums in ongoing studies of the complex helminth fauna characteristic of pikas (Ochotona spp.) in the American west. These studies address the taxonomy for pinworms of the Labiostomatinae and the problems associated with the absence of adequate type series and vouchers and with misidentifications in original descriptions. We demonstrate that the types for Labiostomum (Labiostomum) coloradensis arc identical to some specimens in the syntype series representing L. (Eugenuris) utahensis, although the published descriptions are in disagreement. Both are identical to L. (Eugenuris) talkeetnaeuris and, its;l consequence. arc reduced as junior synonyms. Only 2 species of large pinworms, namely L. (Labiostomum) rauschi and L. (Eugenuris) talkeetnaeuris, are widely distributed in Ochotona collaris and O. princeps. Although this serves to clarify the taxonomy for species in these genera. prior records remain confused, as representative voucher specimens from all major surveys in North America were never submitted to museum collections. We strongly suggest that type and voucher series should not be held in private or personal collections. where such are eventually lost, discarded, or destroyed through neglect due to inattention and the absence of curation. The potential to accumulate meaningful baselines for assessment of environmental change is jeopardized if materials from survey and inventory are not routinely submitted to museum collections. The capacity of museum repositories, as a fools for systematics, ecology, and evolutionary studies and for the development of resources for biodiversity informatics, continues to be undervalued and poorly utilized by a cadre of scientists who arc dependant on accurate and definitive information that transcends specific disciplines.

TI C-13-Breath Tests for Sucrose Digestion in Congenital Sucrase Isomaltase-deficient and Sacrosidase-supplemented Patients SO JOURNAL OF PEDIATRIC GASTROENTEROLOGY AND NUTRITION LA English DT Article DE C-13-breath test; Congenital sucrase-isomaltase deficiency; Glucose oxidation; Sacrosidase supplementation; Sucrose digestion ID MALTASE-GLUCOAMYLASE ACTIVITY; RATIO MASS-SPECTROMETRY; BREATH TEST; STARCH DIGESTION; FERMENTATION; TRANSPORT; CHILDREN; GLUCOSE; ENZYME; MALABSORPTION AB Background: Congenital sucrase-isomaltase deficiency (CSID) is characterized by absence or deficiency of the mucosal sucrase-isomaltase enzyme. Specific diagnosis requires upper gastrointestinal biopsy with evidence of low to absent sucrase enzyme activity and normal histology. The hydrogen breath test (BT) is useful, but is not specific for confirmation of CSID. We investigated a more specific C-13-sucrose labeled BT. Objectives: Determine whether CSID can be detected with the C-13-sucrose BT without duodenal biopsy sucrase assay, and if the C-13-sucrose BT can document restoration of sucrose digestion by CSID patients after oral supplementation with sacrosidase (Sucraid). Methods: Ten CSID patients were diagnosed by low biopsy sucrase activity. Ten controls were children who underwent endoscopy and biopsy because of dyspepsia or chronic diarrhea with normal mucosal enzymes activity and histology. Uniformly labeled C-13-glucose and C-13-sucrose loads were orally administered. (CO2)-C-13 breath enrichments were assayed using an infrared spectrophotometer. In CSID patients, the C-13-sucrose load was repeated adding Sucraid. Sucrose digestion and oxidation were calculated as a mean percent coefficient of glucose oxidation averaged between 30 and 90 minutes. Results: Classification of patients by C-13-sucrose BT percent coefficient of glucose oxidation agreed with biopsy sucrase activity. The breath test also documented the return to normal of sucrose digestion and oxidation after supplementation of CSID patients with Sucraid. Conclusions: C-13-sucrose BT is an accurate and specific noninvasive confirmatory test for CSID and for enzyme replacement management. JPGN 48:412-418, 2009. C1 [Robayo-Torres, Claudia C.; Smith, E.

Pst strain SM78-1Sm(r) (race 0) grew well under field conditions and caused ample bacterial speck disease on susceptible RG plants. In contrast, strain DC3000 failed to establish large populations when inoculated onto field grown RG plants. Mean population sizes of SM78-1Sm(r) were 4-5 orders of magnitude larger on RG than RG-Pto plants indicating that RG-Pto plants were highly effective in attenuating pathogen population development. Most of the sampled leaflets from RG-Pto field plots harboured small numbers of SM78-1Sm(r). However, population sizes SM78-1Sm(r) as large as 10(5)-10(6) CFU were found on a few leaflets. Bacteria isolated from these leaflets had phenotypes characteristic of Pst race 1 strains. In growth chamber plant assays, the bacterial strains grew well and caused typical speck lesions on RG-Pto plants. The strains appeared to be race-shift mutants of SM SM78-1Sm(r). Interestingly, results from DNA hybridization experiments demonstrated that the race-shift mutants were deleted for the avirulence gene, avrPto but not for avrPtoB.

A total of 655 isolates of P. infestans, including 29 isolates from potato, was collected from major tomato and potato production areas of Taiwan during 1991 to 2006. Isolates were characterized for their pathogenicity, mating type, in vitro metalaxyl sensitivity and molecular genotype (including allozyme pattern, mitochondrial genomic haplotype and DNA fingerprint) to monitor population changes in P. infestans. The population of P. infestans in Taiwan underwent a dramatic genetic shift in the 1997-1998 cool growing season. Isolates collected from tomato before 1997 were aggressive to tomato but not potato; most isolates obtained after 1998, were aggressive to both hosts. Metalaxyl sensitivity of isolates changed from sensitive/intermediate before 1997 to resistant since 1998. Similarly, the isolates obtained before 1997 were all US-1 clonal lineage (including variants US-1.1, US-1.2, US-1.3 and US-1.4). During the 1997-1998 cool growing season, the US-11 clonal lineage and the TW-1 genotype appeared, possibly introduced on imported table potatoes. The US-11 lineage spread rapidly and since 1999 has almost completely displaced the old population in Taiwan. Mating type determined by pairing with A1 and A2 reference isolages of P. parasitica, showed all isolates were of the A1 mating type, suggesting that the A2 mating type had not become established in Taiwan. The increasing percentage (up to 42.3% in 2006) of the US-11 variants (including US-11.l, US-11.2, US-11.3 and US-11.4) implied that genomic diversity of the pathogen is changing quickly. Therefore, it is important to continuously monitor the population changes of P. infestans and develop an integrated management strategy for this disease.

Intracerebroventricular (ICV) administration of chicken insulin (120 ng) inhibited food intake in ad libitum chicks over the 120-min experiment period. A lower dose (2 ng) also shows a suppressive effect at 60 min post-injection. but not at 30 and 120 min. Similar to chicken insulin, a higher dose of porcine insulin (20 ng) significantly inhibited food intake at 60 and 120 min post-injection, but a significant difference is not detected at 30 min post-injection. Treatment with human and bovine insulin had no effect in this study. Finally, we compared the effect of ICV injection of chicken and porcine insulin oil food consumption in starved chicks. The results of the present study indicate that chicken insulin has a higher potent ability to depress feeding behavior in the CNS compared with porcine. human, and bovine insulin. Therefore, it seems that the ranking in order of potency of the insulins on the anorexic effect in neonatal chick's is chicken insulin > porcine insulin > human insulin > bovine insulin. It is suggested that the 8(th)-10(th) amino acids of the A-chain and/or the C-terminal amino acid of the B-chain in insulin have an important role in bioactivity in the CNS with special reference to feeding behavior.

However. limited information exists on the underlying mechanisms responsible for these effects. The present investigation was conducted to examine the ability of three Korean indigenous fruits (Persimmon, raspberry and tomato) to stimulate lymphocyte proliferation and macrophage nitric oxide production as parameters of innate immunity, and to inhibit tumor cell growth. In vitro co-culture of chicken spleen lymphocytes with methanol extracts of persimmon (Diospyros kaki) or tomato (Lycopersicon esculentum) induced greater cell proliferation compared with cells treated with the vehicle control. Stimulation of chicken macrophages with extracts of persimmon or raspberry (Rubus crategifolius). but not tomato, stimulated robust nitric oxide production to levels similar to that produced by interferon-gamma. All fruit extracts uniformly inhibited the growth chicken tumor cells in vitro. These results provide a rational basis for future Studies investigating the effects of medicinal fruits on innate immunity and carcinogenesis in humans and animals.

White Leghorn chickens were fed a standard diet with or without safflower leaf and were either uninfected or orally infected with 5,000 sporulated oocysts of Eimeria acervulina. Protective immunity was assessed by body weight gain, fecal oocyst shedding, splenic lymphocytes proliferation, T lymphocyte sub-populations. and proinflammatory cytokine gene expression. We observed that the effect of safflower on experimental coccidiosis was dependant on the close of the supplement used. A 0.1%/ (wt/wt) safflower-supplemented diet increased body weight gains of coccidia-infected chickens to a level identical to that of uninfected controls, and significantly reduced fecal oocyst shedding compared with animals that were given a non-supplemented standard diet. Furthermore, increased splenic lymphocyte proliferation as well as greater percentages of CD4((sic)) T cells and decreased CD8((sic)) cells were observed in animals Fed a 0.1%, safflower-supplemented diet. Finally. IFN-gamma, IL-8, IL-15 and IL-17 transcripts in the 0.1% safflower-supplemented group were higher than the non-supplemented controls. These results indicate that safflower leaf when given as a dietary supplement possesses immune-enhancing properties that augment protective immunity against experimental coccidiosis.

Compared with native rice flour, the steam jet-cooked rice flour exhibited significantly increased hydration properties. Its pasting properties were also characterized by cold initial viscosity, decreased setback and the lack of peak viscosity. The shear-thinning behaviors of the steam jet-cooked rice flour were satisfactorily fitted into the Carreau equation. In addition, dynamic viscoelastic measurements showed that the liquid-like nature was more dominant over the solid-like properties. When incorporated into frying batter formulations, the steam jet-cooked rice flour increased the batter viscosity and pickup. The use of steam jet-cooked rice flour also enabled fried batters to control the moisture loss effectively. Furthermore, the wheat flour replacement with 20% steam jet-cooked rice flour in batters led to dramatic reduction of oil uptake by around 40%.

The aim of this study was to examine the relationship between carbohydrate intake and dietary glycemic index and several cardiovascular disease risk factors. Methods: We examined cross-sectional associations between total carbohydrate and dietary glycemic index (GI) intakes and several cardiovascular disease risk factors (CVD) in a sample of 2,941 Framingham Offspring Participants. CVD risk factors included waist, blood pressure, lipids, fasting insulin, fasting glucose, and the insulin sensitivity index (ISI(0.120)). Dietary intake was assessed by a food frequency questionnaire (FFQ) and categorized by quintiles of dietary intake. Results: After adjustment for potential confounding factors, dietary GI was positively associated with fasting triglycerides (mean: 115mg/dL in the lowest and 127 mg/dL in the highest quintile of intake; P for trend < 0.001), fasting insulin (26.8 and 28.9 mu u/mL, respectively, P for trend < 0.0001), and inversely associated with HDL cholesterol (49 and 47 mg/dL, respectively, P for trend 0.003) and ISI(0.120) (26.8 and 25.1, P for trend <0.001). There was no significant relationship between dietary GI and waist circumference, total cholesterol, LDL cholesterol and fasting glucose. Intakes of total carbohydrate were inversely associated with waist circumference and HDL cholesterol, and positively associated with fasting triglycerides. Conclusion: These cross-sectional findings support the hypothesis that a high GI diet unfavorably affects CVD risk factors and therefore, substitution of high with low GI dietary carbohydrates may have reduce the risk of CVD.

Methods: Zn absorption was measured at 0, 8, and 16 wk in healthy postmenopausal women who consumed controlled diets with similar to 5 mg Zn from food, supplemented to 14 (n = 6), 32 (n = 3), or 47 (n = 3) mg Zn/d for 22 wk. Zn absorption for 1 day was determined by Zn-65-labeling of meals and whole body scintillation counting. Results: At wk 0, less Zn was absorbed from diets with 14, compared with 32 or 47 mg/d (4.6, 8.7, and 10.3 mg/d, respectively; pooled SE = 0.9; p < 0.05). These differences were not apparent at wk 8 (5.4, 5.8, 6.4; NS) and became negligible by wk 16 (5.0, 5.0, 5.1; NS). Plasma Zn concentrations were unaffected. The results are consistent with a saturation response model of Zn absorption. Conclusion: Within several weeks, postmenopausal women biologically adapted to absorb a relatively uniform amount of 5 mg Zn/d when controlled, Zn-supplemented diets supplied consistent Zn intakes between 14 and 47 mg/d.

A convenience sample of 184 parents of low socioeconomic status completed one-time, self-administered questionnaires assessing demographic information, acculturation, and food insecurity in the spring of 2006. In addition, children's fruit and vegetable intake at home was measured using a validated seven-item index. Parents were recruited through local elementary schools in San Antonio, TX. Pearson and Spearman correlations were used to examine the associations between the variables. t tests were used to explore the differences in means of children's fruit and vegetable intake at home for acculturation and food insecurity levels. Statistical significance was set at P<0.05. Significant correlations were found between demographic variables, acculturation, food insecurity, and children's fruit and vegetable intake at home. The overall mean fruit and vegetable intake at home was 1.04 +/- 0.63 (mean standard deviation) servings per day. Higher rates of acculturation and higher rates of food insecurity were associated with lower fruit and vegetable intake at home. The findings reported in this study suggest a need for culturally tailored interventions targeting Hispanic children because fruit and vegetable intake at home among Hispanic children was low, regardless of the level of acculturation or food insecurity.

Typically, petroleum-based products are used to improve the final appearance and feel Of Crust leather. In this Study, we demonstrate that blends composed of whey protein isolate (WPI), I byproduct of the cheese Industry, and small amounts of gelatin, a byproduct of the leather industry, could be effectively used as filling agents for both shoe upper and upholstery leather. Wet blue leather from three different areas in the hide (butt, belly and neck) was treated with the WPI-gelatin blend, retanned, colored and fatliquored, and their Subjective and mechanical properties evaluated. The effect of pretreatment of the wet blue samples with various concentrations of the enzyme microbial transglutaminase (mTGase) was also examined. It was found that the rate Of uptake of the WPI-gelatin blend by upholstery wet blue increased four-fold when it was pretreated with a 2.5% mTGase solution. Conversely, this rate was decreased when shoe upper was pretreated with increasing amounts of mTGase. The subjective properties (e.g. handle, fullness, color and grain break) of both shoe upper and upholstery leather that were treated with the WPI-gelatin blend were significantly improved over the controls. Importantly, the grain break of the belly area of samples (hat were pretreated with enzyme (both upholstery and shoe upper) was remarkably improved. Hence, fillers mainly composed by the less expensive WPI were demonstrated to be effective filling agents for both upholstery and shoe upper leather.

Goldberg, Neil M. Cooke, Perer TI COMPOSITE DRYING WITH SIMULTANEOUS VACUUM AND TOGGLING SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID LEATHER; ENERGY AB Drying is one of key steps to govern the physical properties of leather and it is where leather acquires its final texture, consistency and flexibility. Recently we have been working diligently to improve chrome-free leather by optimizing its drying process. We developed a drying method using a combination of to-le and vacuum drying together. This Is because vacuum drying offers fast speed at a low temperature, which is particularly advantageous to heat-vulnerable chrome-free leathers. On the other hand, adding a toggle action during vacuum drying can significantly increase the area yield. We explored this composite drying method and investigated how drying variables affect mechanical properties and area yield of chrome-free leather. This study showed that the stretch applied in a drying operation significantly affects stiffness and area yield. We observed that biaxial stretch increases tensile strength but has less effect on fracture energy. Our Study also showed that tensile strength increases with apparent density and decreases with drying rate. Under an optimal drying condition, a 16% increase in area yield with good properties can be achieved.

TI Comparisons of Biodiesel Produced from Unrefined Oils of Different Peanut Cultivars SO JOURNAL OF THE AMERICAN OIL CHEMISTS SOCIETY LA English DT Article DE Biodiesel; Crystallization; Viscosity ID DIESEL FUEL LUBRICITY; ACID METHYL-ESTERS; CRYSTALLIZATION TEMPERATURE; KINEMATIC VISCOSITY; VEGETABLE-OILS; BLENDS AB Biodiesels were prepared according to standard procedures from unrefined oils of eight commercially available peanut cultivars and compared for differences in physical properties important to fuel performance. Dynamic viscosity, kinematic viscosity and density were measured from 100 to 15 degrees C, and differences (p < 0.05) in these physical properties occurred more frequently at lower temperatures when comparing the different cultivars. Unlike data for the oil feedstocks, no meaningful correlations among biodiesel fatty acid profiles and either fuel viscosity or density were observed. Low temperature crystallization of the peanut biodiesels was measured via differential scanning calorimetry. Increased concentrations of long chain saturated fatty acid methyl esters (FAME) were associated with an increased propensity for low temperature crystallization, and the single FAME category most associated with low temperature crystallization was C:24. Tempering at 10 degrees C followed by analysis of the soluble fractions (winterization), improved crystallization properties and confirmed the importance that long chain saturated FAMEs play in the final functionality of peanut biodiesel. Peanut data is also compared to data for canola and soy biodiesels, as these feedstocks are more common worldwide for biodiesel production. Overall, this work suggests that minimizing the concentration of long chain saturated FAMEs within peanut biodiesel, either through processing and/or breeding efforts would improve the low temperature performance of peanut biodiesel.

Have Greater Nut Yields Than Native Trees at Similar Trunk Cross-Sectional Areas SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY LA English DT Article AB Orchard production of eastern black walnut (Juglans nigra L.,) cultivars may be the best way to stabilize the Supply of nuts. The objective of this study was to determine if the relationship between trunk cross-sectional area (TCSA) and nut yield is different between cultivars of black walnut and native trees. Data were collected from 13 stands of black walnut (six stands of native trees and seven stands of cultivars) growing in open canopy or free-to-grow circumstances in the central United States for two consecutive years (2002-2003). The regression equations between two-year mean for nut yield per tree and trunk cross-sectional area (TCSA) were highly significant for data from native trees and cultivars of black walnut; however the slopes and Y-intercepts differed. For cultivars, the equation was: two-year mean yield (kg per tree) = 0.0071*(mean TCSA. cm(2)) + 1.38. For native trees, the equation was: two-year mean yield (kg per tree) = 0.0049*(mean TCSA. cm(2)) -0.11. When various independent variables were assessed as predictors of two-year means for yield among the 13 stands, the regression equations generated by backward selection included two variables: 1) the tree stock type, i.e. cultivars versus native trees: 2) g annual mean increase in TCSA. These analyses indicate that cultivars did differ front native trees in the relationship between TCSA and nut yield per tree. C1 [Brauer, David] ARS, USDA, Bushland, TX 79012 USA.

TI Importance of Scion Cultivar in Peach Tree Short Life SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY LA English DT Article ID ROOTSTOCK; SURVIVAL; GROWTH AB In the Southeastern United States Peach [Prunus persica (L.) Batsch] trees planted on sites previously planted with peaches often suffer front Peach Tree Short Life (PTSL) syndrome, in which ring nematode [Mesocriconema xenoplax (Raski) Loof & de Grisse], cold injury, and bacterial canker (Pseudomonas syringae pv. syringae van Hall) combine to kill the scion in the spring. Rootstock plays an important role; where PTSL is present, trees on Guardian (R) 'BY520-9' rootstock survive better than those on Lovell and Much better than those on Nemaguard. Little is known about the role of scion cultivar in susceptibility to PTSL, Previous Studies looking at the role of cultivar showed ambiguous results. This study, done in both South Carolina and Georgia. suggests that environmental variability associated with the plantings makes it difficult to reliably separate most commercial cultivars into susceptibility classes. cultivar Susceptibility in the previous experiments were not well correlated with the results of this test, nor with each other, More replications are needed for reliable screening of commercial Scion cultivars.

TI A MULTILEVEL MODEL OF THE IMPACT OF FARM-LEVEL BEST MANAGEMENT PRACTICES ON PHOSPHORUS RUNOFF SO JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION LA English DT Article DE nonpoint source pollution; best management practices; nutrients; multilevel models; nutrients; hierarchical models ID POLLUTION AB Multilevel or hierarchical models have been applied for a number of years in the social sciences but only relatively recently in the environmental sciences. These models can be developed in either a frequentist or Bayesian context and have similarities to other methods such as empirical Bayes analysis and random coefficients regression. In essence, multilevel models take advantage of the hierarchical structure that exists in many multivariate datasets; for example, water quality measurements may be taken from individual lakes, lakes are located in various climatic zones, lakes may be natural or man-made, and so on. The groups, or levels, may effectively yield different responses or behaviors (e.g., nutrient load response in lakes) that often make retaining group membership more effective when developing a predictive model than when working with either all of the data together or working separately with the individuals. Here, we develop a multilevel model of the impact of farm level best management practices (BMPs) on phosphorus runoff. The result of this research is a model with parameters which vary with key practice categories and thus may be used to evaluate the effectiveness of these practices on phosphorus runoff. For example, it was found that the effect of fertilizer application rate on farm-scale phosphorus loss is a function of the application method, the hydrologic soil group, and the land use (crop type). Further, results indicate that the most effective method for controlling fertilizer loss is through soil injection. In summary, the resultant multilevel model can be used to estimate phosphorus loss from farms and hence serve as a useful tool for BMP selection. C1 [Reckhow, K. H.; Qian, S.

Its applicability needs to be evaluated for use in a new region or climate. The objectives were to: (1) evaluate the reproducibility of the latest version of CLIGEN v5.22564 in generating daily, monthly, and yearly precipitation depths at 12 stations, as well as storm patterns including storm duration (D), relative peak intensity (ip), and peak intensity (rp) at 10 stations dispersed across the Loess Plateau and (2) test whether an exponential distribution for generating D and a distribution-free approach for inducing desired rank correlation between precipitation depth and D can improve storm pattern generations. Mean absolute relative errors (MAREs) for simulating daily, monthly, annual, and annual maximum daily precipitation depth across all 12 stations were 3.5, 1.7, 1.7, and 5.0% for the mean and 5.0, 4.5, 13.0, and 13.6% for the standard deviations (SD), respectively. The model reproduced the distributions of monthly and annual precipitation depths well (p > 0.3), but the distribution of daily precipitation depth was less well produced. The first-order, two-state Markov chain algorithm was adequate for generating precipitation occurrence for the Loess Plateau of China; however, it underpredicted the longest dry periods. The CLIGEN-generated storm patterns poorly. It underpredicted mean and SD of D for storms >= 10 mm by -60.4 and -72.6%, respectively. Compared with D, ip, and rp were slightly better reproduced. The MAREs of mean and SD were 21.0 and 52.1% for ip, and 31.2 and 55.2% for rp, respectively. When an exponential distribution was used to generate D, MAREs were reduced to 2.6% for the mean and 7.8% for the SD. However, ip estimation became much worse with MAREs being 128.9% for the mean and 241.1% for the SD. Overall, storm pattern generation needs improvement. For better storm pattern generation for the region, precipitation depth, D, and rp may be generated correlatively using Copula methods.

Available tools to predict phosphorus loss from agricultural fields are either: (1) qualitative indices with limited applicability to address offsite water quality standards, or (2) models which are prohibitively complex for application by most conservation planners. The purpose of this research was to develop a simple interface for a comprehensive hydrologic/water quality model to allow its usage by farmers and conservation planners. The Pasture Phosphorus Management (PPM) Calculator was developed to predict average annual phosphorus (P) losses from pastures under a variety of field conditions and management options. PPM Calculator is a vastly simplified interface for the Soil and Water Assessment Tool (SWAT) model that requires no knowledge of SWAT by the user. PPM Calculator was validated using 33 months of data on four pasture fields in northwestern Arkansas. This tool has been extensively applied in the Lake Eucha/Spavinaw Basin in northeastern Oklahoma and northwestern Arkansas. PPM Calculator allows conservation planners to take advantage of the predictive capacity of a comprehensive hydrologic water quality model typically reserved for use by hydrologists and engineers. This research demonstrates the applicability of existing water quality models in the development of user friendly P management tools.

TI EVALUATION OF A WATERSHED MODEL FOR ESTIMATING DAILY FLOW USING LIMITED FLOW MEASUREMENTS SO JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION LA English DT Article DE Soil and Water Assessment Tool; daily flow estimation; model evaluation; Upper Oyster Creek watershed; Texas ID SWAT; VALIDATION; MANAGEMENT; TEXAS AB The Soil and Water Assessment Tool (SWAT) model was evaluated for estimation of continuous daily flow based on limited flow measurements in the Upper Oyster Creek (UOC) watershed. SWAT was calibrated against limited measured flow data and then validated. The Nash-Sutcliffe model Efficiency (NSE) and mean relative error values of daily flow estimations were 0.66 and 15% for calibration, and 0.56 and 4% for validation, respectively. Also, further evaluation of the model's estimation of flow at multiple locations was conducted with parametric paired t-test and nonparametric sign test at a 95% confidence level. Among the five main stem stations, four stations were statistically shown to have good agreement between predicted and measured flows. SWAT underestimated the flow of the fifth main stem station possibly because of the existence of complex flood control measures near to the station. SWAT estimated the daily flow at one tributary station well, but with relatively large errors for the other two tributaries. The spatial pattern of predicted flows matched the measured ones well. Overall, it was concluded from the graphical comparisons and statistical analyses of the model results that SWAT was capable of reproducing continuous daily flows based on limited flow data as is the case in the UOC watershed.

TI Regimes of Dry Convection above Wildfires: Idealized Numerical Simulations and Dimensional Analysis SO JOURNAL OF THE ATMOSPHERIC SCIENCES LA English DT Article ID ATMOSPHERE-FIRE MODEL; WILDLAND FIRES; CELL REGENERATION; DYNAMICS; VORTICES; IMAGERY; FOREST; STORM; SMOKE AB Wildfires are capable of inducing atmospheric circulations that result predominantly from large temperature anomalies produced by the fire. The fundamental dynamics through which a forest fire and the atmosphere interact to yield different convective regimes is still not well understood. This study uses the Advanced Regional Prediction System (ARPS) model to investigate the impact of the environmental (i.e., far upstream, undisturbed by fire) wind profile on dry convection above a prescribed heat source of an intensity and spatial scale comparable to a wildfire. Dimensional analysis of the fire-atmosphere problem provides two relevant parameters: a surface buoyancy parameter that addresses the amount of heat a parcel of air receives in transiting above the fire and an advection parameter that addresses the degree to which the environmental wind advects updrafts away from the fire. Two-dimensional simulations are performed in which the upstream surface wind speed and mixed layer mean wind speed are varied independently to better understand the fundamental processes governing the organizational mode and updraft strength. The result of these experiments is the identification of two primary classes of dry convection: plume and multicell. Simulated plume cases exhibit weak advection by the mean wind and are subdivided into intense plume and hybrid classes based on the degree of steadiness within the convection column. Hybrid cases contain columns of largely discrete updrafts versus the more continuous updraft column associated with the intense plume mode. Multicell cases develop with strong mixed layer advection and are subdivided into strong and weak classes based on the depth of convection. Intense plume and strong multicell (hybrid and weak multicell) cases occur when the surface buoyancy is large (small). Parcel analyses are performed to more closely examine the forcing of convection within different areas of the parameter space. The multicell (strong and weak) and intense plume modes are forced by a combination of buoyancy and dynamic pressure gradient forcing associated with the perturbation wind field, whereas the hybrid mode is forced by a combination of buoyancy and dynamic pressure gradient forcing associated with the strong background shear. The paper concludes with a discussion of the degree of nonlinearity that is likely to exist at the fire front for each of the convective modes; nonlinear fire behavior is most likely for the hybrid mode and least likely for the weak multicell mode. Knowledge of the sensitivity of the convective mode to upstream conditions can provide information about the degree of nonlinear or erratic fire behavior expected for a given wind profile upstream of the fire.

Macbr., L. montanum Nutt., and L. davisii Rollins (Brassicaceae). J. Torrey Bot. Soc. 136: 149-163. 2009.-Previous phylogenetic analyses of Lepidium included only a few accessions of L. montanum, L. flavum, and L. fremontii to represent western North American species. Two additional species endemic to southwest Idaho have posed both taxonomic and conservation questions regarding their species status. Lepidium papilliferum was originally described as a variety of L. montanum, is morphologically similar to L. montanum, and is found in small scattered populations in southwest Idaho. The plant is restricted to specific edaphic conditions known as slick spots where high clay content creates conditions amenable to L. papilliferum, but to few other species. Resolving whether the populations of L. papilliferum merit species status distinct from L. montanum is a vexing question and phylogenetic analyses can assist in resolving this issue. Like L. papilliferum, L. davisii has specific edaphic requirements and is found in playas, areas similar to slick spots, but larger and with deeper soils. Unlike L. papilliferum, L. davisii is morphologically distinct from L. montanum and has posed less of a taxonomic quandary. Previous phylogenetic studies have shown that American species of Lepidium are derived from an ancestral allopolyploid species. In this study we have expanded previous analyses to include L. papilliferum, L. davisii, and several accessions of L. montanum along with published sequences of ITS, cpDNA, and PISTILLATA first intron. The western North American species form a monophyletic group with L. davisii sister to the remainder of the clade. Within this clade, L. papilliferum and L. fremontii are each monophyletic and sister to each other, but are imbedded within a paraphyletic L. montanum.

TI Evaluation of Poultry By-product Meal in Commercial Diets for Hybrid Striped Bass, Morone chrysops female x Morone saxatilis male, in Pond Production SO JOURNAL OF THE WORLD AQUACULTURE SOCIETY LA English DT Article ID TROUT ONCORHYNCHUS-MYKISS; SULFUR AMINO-ACIDS; FINGERLING CHANNEL CATFISH; FISH-MEAL; ARGININE REQUIREMENT; PRACTICAL DIETS; FINISHING SWINE; DICENTRARCHUS-LABRAX; NUTRIENT UTILIZATION; AMMONIA EXCRETION AB The efficacy of replacing fish meal with petfood-grade poultry by-product meal (PBM) on an ideal protein basis in commercial diets for hybrid striped bass (HSB) was evaluated under production conditions in pond culture. A generic production diet (GEN) for HSB was formulated to contain 45% protein, 12% lipid, and 3.7 kcal/kg. Protein in the generic diet was supplied by a mix of animal and plant sources typically used by the industry that included more than 20% select menhaden fish meal and less than 10% PBM. A positive control diet (GEN + AA) was formulated by supplementing the generic diet with feed-grade Met and Lys to match the level of those amino acids in HSB muscle at 40% digestible protein. Substitution diets were formulated by replacing 35, 70, or 100% of fish meal in the GEN diet with PBM on a digestible protein basis and then supplementing with Met and Lys (designated 35PBM, 70PBM, and 100PBM, respectively) as needed to maintain concentrations equal to those in the GEN + AA diet. Diet formulation and extrusion were conducted by a commercial mill, and all diets met or exceeded known nutritional requirements for HSB. Twenty 0.10-ha ponds (4 ponds/diet) were randomly stocked with juvenile HSB (76 +/- 10 g; mean +/- SD) at a density of 7400/ha and fed for 600 d (October 2004 to May 2006). Diets were fed once daily to apparent satiation to a maximum of 95 kg feed/ha. Total weight and number of fish in each pond were determined at harvest. Weight distributions in each pond were estimated by selecting every 15th fish during harvest. Subsets of ten fish from each of these samples were selected randomly for the determination of body composition and nutrient and energy retention. The availability of indispensable amino acids as well as ammonia production from the commercial test diets were determined in separate tank trials. Most production characteristics were not statistically different (P > 0.10) among dietary treatments. Distributions of individual fish weights from each of the ponds were not affected by poultry by-product level in the diet. Multivariate analysis of body compositional indices grouped diets into two clusters composed of GEN, GEN + AA, 35PBM vs. 70PBM, and 100PBM mainly because fish fed the 70PBM and 100PBM diets had greater (P = 0.001) body fat (visceral somatic indices) than fish fed the other diets. Ammonia production in tanks was not different among diets and peaked 6-8 h after feeding when fish were fed at 1.5% of body weight; ammonia-N excretion ranged from 197 to 212 mg/kg/d and 18.5-21.5% of nitrogen intake. Some imbalances in the levels and ratios of selected amino acids to Lys were found in the diets containing higher amounts of PBM and were attributed to a lack of accurate availability coefficients during formulation for some dietary proteins. These imbalances in essential amino acids may have been the predominant factor in the somewhat fattier fish observed fed diets containing the two highest levels of PBM. Nevertheless, these results from fish stocked at commercial densities and raised to market size in ponds suggest that formulating diets on an available amino acid basis for all protein sources while balancing limiting amino acids, particularly Met, Lys, Thr, and Trp, on an ideal protein basis will yield significant improvements in HSB performance when fed commercial diets in which all fish meal is replaced with PBM.

Five diets containing 0, 10, 20, 30, and 40% DDGS with supplemental lysine (Diets 1-5) as partial replacements of a combination of soybean meal and cornmeal on an equal protein basis were fed to juvenile catfish (13.33 +/- 0.25 g) for 12 wk. Growth performance and feed utilization efficiency were similar for fish in all treatments. Body lipid and moisture increased and decreased, respectively, in fish feed DDGS-containing diets relative to the control group. Dietary treatment had no effect on red and white blood cell counts. Hemoglobin and hematocrit were significantly higher in fish fed diets containing DDGS than in those fed the control diet. Fish fed 20-40% DDGS diets had increased serum total immunoglobulin, and those fed the 30% DDGS diet had significantly increased antibody titers 21 d following E. ictaluri challenge. Other immune variables evaluated were not affected by dietary treatments. Preliminary results on bacterial challenge showed an increased resistance against E. ictaluri in fish fed DDGS-containing diets (Diets 2-5).

Because 2nd and 3rd generation nucleotide sequencers do not rely on molecular cloning of viral DNA, there is a need to develop methods for isolating highly pure DNA from these viruses. The cell-associated alphaherpesvirus Marek's disease virus (MDV-1) was chosen as a test virus for the development of such methodologies. The genomes of six MDV-1 strains have previously been sequenced using both Sanger dideoxy sequencing and 454 Life Sciences pyrosequencing. These genomes largely represent cell culture adapted strains due to the difficulty in obtaining large quantities of DNA from true low passage isolates. There are clear advantages in analyzing MDV-1 virus taken directly from infected tissues or low passage isolates since serial passage attenuates the virus. Procedures using an ATP-dependent exonuclease and Phi29 DNA polymerase to degrade host DNA selectively and amplify MDV-1 DNA enzymatically from total DNA preps were attempted without much success. Ultimately, however, a protocol was developed for purification of low passage MDV-1 DNA from infected avian fibroblasts. The method builds upon and extends available protocols based on hypotonic lysis to release virus particles followed by micrococcal nuclease treatment to degrade cellular DNA. Intact high-molecular weight viral DNA is purified away from an excess of degraded cellular DNA using polyethylene glycol precipitation. 454-based pyrosequencing of viral DNA purified in this manner has generated data containing as little as 2.3% host sequence. On average, DNA preparations were 70% (+/-20%) pure yielding a genome coverage range of 25-74-fold.

TI Pathogenesis of 1918 Pandemic and H5N1 Influenza Virus Infections in a Guinea Pig Model: Antiviral Potential of Exogenous Alpha Interferon To Reduce Virus Shedding SO JOURNAL OF VIROLOGY LA English DT Article ID LOWER RESPIRATORY-TRACT; GENE PROTECTS MICE; A H5N1; HONG-KONG; EPITHELIAL-CELLS; RECEPTOR SPECIFICITY; CYTOKINE RESPONSES; ISOLATED WORLDWIDE; POSITIVE FEEDBACK; PLUS RIBAVIRIN AB Although highly pathogenic avian influenza H5N1 viruses have yet to acquire the ability to transmit efficiently among humans, the increasing genetic diversity among these viruses and continued outbreaks in avian species underscore the need for more effective measures for the control and prevention of human H5N1 virus infection. Additional small animal models with which therapeutic approaches against virulent influenza viruses can be evaluated are needed. In this study, we used the guinea pig model to evaluate the relative virulence of selected avian and human influenza A viruses. We demonstrate that guinea pigs can be infected with avian and human influenza viruses, resulting in high titers of virus shedding in nasal washes for up to 5 days postinoculation (p.i.) and in lung tissue of inoculated animals. However, other physiologic indicators typically associated with virulent influenza virus strains were absent in this species. We evaluated the ability of intranasal treatment with human alpha interferon (alpha-IFN) to reduce lung and nasal wash titers in guinea pigs challenged with the reconstructed 1918 pandemic H1N1 virus or a contemporary H5N1 virus. IFN treatment initiated 1 day prior to challenge significantly reduced or prevented infection of guinea pigs by both viruses, as measured by virus titer determination and seroconversion. The expression of the antiviral Mx protein in lung tissue correlated with the reduction of virus titers. We propose that the guinea pig may serve as a useful small animal model for testing the efficacy of antiviral compounds and that alpha-IFN treatment may be a useful antiviral strategy against highly virulent strains with pandemic potential.

Fecal collected from 430 plateau pikas were examined by the modified McMaster technique, which revealed that 83% of the samples contained eggs from two or more helminth species. Mean fecal egg counts were generally moderate and showed the same trend irrespective of the age, or sex of the pikas. The prevalence, and counts of cestode eggs showed strong seasonal relationships that corresponded with the rainfall pattern in the study area during the study period. Of the 430 plateau pika examined at necropsy, 89% contained adult nematode or cestode species, but none of these contained adult trematode species or protozoans. Overall, six genera of adult nematodes including Oesophagostomum sp., Cephaluris coloradensis, Eugenuris schumakowiescsi, Haemonchus sp., Trichuris sp., and Chbertiinae sp.; three genera of adult cestodes including Schizorchis sp., Ochotonae sp., and Hymenolepis nana; three ectoparasite species including Hypoderma curzonial, Pulex sp., and Ixodes ovatus; and one proscolex stage of a cestode, Echinococcus multilocularis or Echinococcus shiquicus, were encountered during the study. Other genera examined occurred in low numbers, which did not allow any meaningful comparisons. Overall, results suggest that four parasite species, Hypoderma curzonial, Pulex sp., Ixodes ovatus Neumann, and Cephaluris coloradensis, may be regulating factors in controlling future numbers of plateau pika in this study area. These data provide evidence of a natural biologic control mechanism of plateau pika on grassland habitats, and may be of use for identifying the mechanism of transmission of parasites between plateau pika, livestock, and humans.

We also used automated cameras to determine the potential for inter- and intraspecific interaction at skunks' diurnal resting sites and nocturnal focal locations. We found no difference between sexes in nightly rates of travel or in size of seasonal home range. Nightly rates of travel were greatest in the postbreeding months (May-July) and smallest from November to February, consistent with larger home ranges (95% kernel estimates) from March-August and smaller home ranges from September-February. Sixty-three percent of monitored males and 38% of monitored females crossed the urban-wildland interface, in at least one direction on at least one night, and some remained outside the urban area for days or weeks, indicating that skunks could act as vectors of disease across the urban-wildland interface. We recorded co-occurrence of skunks with domestic cats (Felis domesticus), raccoons (Procyon lotor), gray foxes (Urocyon cinereoargenteus), and other skunks at focal locations and diurnal retreats used by skunks, suggesting these areas are potential sites for both inter- and intraspecific rabies transmission and could be targeted by wildlife managers during trapping or vaccination programs.

Domestic swine are, widely regarded as vulnerable to diseases harbored by feral swine. Our objectives were to determine antibody prevalence for selected pathogens in Texas feral swine populations and identify contact events between feral and domestic swine. Overall prevalence of antibodies against brucellosis and pseudorabies virus was 11% and 30%, respectively. Antibodies to porcine reproductive and respiratory disease virus were detected in 3% of feral swine front southern Texas. All samples tested negative for antibodies to classical swine fever virus. To determine the frequency of contact events between feral swine and domestic swine in neighboring Facilities, we analyzed movement data from 37 adult feral swine that were trapped <= 10 km from domestic swine facilities and equipped with geographic positioning system collars. Seven of the 37 feral swine had contact (relocated within 100 m) with domestic swine. We found that contact between feral swine and domestic swine occurred predominantly at night. Additionally, we analyzed 60 consecutive days of experimental track plots around pens that contained domestic swine and empty control pens, and found greater visitation by feral swine to the domestic swine pens. Our data demonstrate that Feral swine have direct contact with domestic swine, which presents opportunity for disease transmission. C1 [Wyckoff, A.

TI Behavioral Responses of North American Elk to Recreational Activity SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE all-terrain vehicles (ATVs); Cervus elaphus; elk; elk behavior; hiking; horseback riding; human disturbance; mountain biking; recreation ID ROCKY-MOUNTAIN ELK; MULE DEER; WILDLIFE; ROADS; MOVEMENTS AB Off-road recreation on public lands in North America has increased dramatically in recent years. Wild ungulates are sensitive to human activities, but the effect of off-road recreation, both motorized and nonmotorized, is poorly understood. We measured responses of elk (Cervus elaphus) to recreational disturbance in northeast Oregon, USA, from April to October, 2003 and 2004. We subjected elk to 4 types of recreational disturbance: all-terrain vehicle (ATV) riding, mountain biking, hiking, and horseback riding. Motion sensors inside radiocollars worn by 13 female elk recorded resting, feeding, and travel activities at 5-minute intervals throughout disturbance and control periods. Elk fed and rested during control periods, with little time spent traveling. Travel time increased in response to all 4 disturbances and was highest in mornings. Elk travel time was highest during ATV exposure, followed by exposure to mountain biking, hiking, and horseback riding. Feeding time decreased during ATV exposure and resting decreased when we subjected elk to mountain biking and hiking disturbance in 2003. Our results demonstrated that activities of elk can be substantially affected by off-road recreation. Mitigating these effects may be appropriate where elk are a management priority. Balancing management of species like elk with off-road recreation will become increasingly important as off-road recreational uses continue to increase on public lands in North America.

Knowledge is limited on the effects of reverting agriculture to native grass, and vice versa, on size of home range and habitat use of white-tailed deer (Odocoileus virginianus). We followed 68 radiocollared female deer from 1991 through 2004 that were residents of DeSoto National Wildlife Refuge (DNWR) in eastern Nebraska, USA. The refuge was undergoing conversion of vegetation out of row-crop agriculture and into native grass, forest, and emergent aquatic vegetation. Habitat in DNWR consisted of 30% crop in 1991 but removing crops to establish native grass and wetland habitat at DNWR resulted in a 44% reduction in crops by 2004. A decrease in the amount of crops on DNWR contributed to a decline in mean size of annual home range from 400 ha in 1991 to 200 ha in 2005 but percentage of crops in home ranges increased from 21% to 29%. Mean overlap for individuals was 77% between consecutive annual home ranges across 8 years, regardless of crop availability. Conversion of crop to native habitat will not likely result in home range abandonment but may impact disease transmission by increasing rates of contact between deer social groups that occupy adjacent areas. Future research on condition indices or changes in population parameters (e. g., recruitment) could be incorporated into the study design to assess impacts of habitat conversion for biofuel production.

TI Factors Affecting Golden-Cheeked Warbler Nest Survival in Urban and Rural Landscapes SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE Dendroica chrysoparia; edge effects; golden-cheeked warbler; information-theoretic approach; nest survival; rural; temporal effects; Texas; urban ID HABITAT USE; PREDATION; EDGE; SUCCESS; FORESTS AB We evaluated hypotheses concerning temporal, landscape, and habitat effects on nest survival of golden-cheeked warblers (Dendroica chrysoparia) in an urban and a rural landscape during the breeding seasons of 2005 and 2006 in central Texas, USA. We found support for temporal effects of year and cubic effect of date and included them in candidate models that evaluated habitat and landscape effects. Nest survival was lower in 2006 than in 2005 and decreased nonlinearly as the breeding season progressed. We found support for edge effects with decreased nest survival nearer edges and in areas with increased open edge density (wooded habitat abutting open habitat) or decreased trail density. However, confidence intervals for the model-averaged odds ratios overlapped 1.0 for all edge variables. Overall daily survival rate was 0.964 (95% CI = 0.949-0.975), resulting in a 25-day period survival of 0.398 (95% CI = 0.269-0.524). Period survival in Austin's urban landscape (0.399, 95% CI = 0.270-0.526) was similar to survival in Fort Hood's rural landscape (0.396, 95% CI = 0.261-0.528). Both landscapes likely support self-sustaining populations based on reasonable assumptions for adult survival and number of nesting attempts. We suggest that some large urban preserves can provide breeding habitat of comparable quality to rural locations and recommend protecting large parcels (>100 ha) of breeding habitat with limited fragmentation and reducing the amount of wooded edge abutting open habitat to ensure nest survival regardless of their landscape context.

ID COMMUNIS L. OIL AB Ricinoleate, a monohydroxy fatty acid, in castor oil has many industrial uses. Dihydroxy fatty acids can also be used in industry. The C(18) HPLC fractions of castor oil were analyzed by electrospray ionization mass spectrometry of lithium adducts to identify the acylglycerols containing dihydroxy fatty acids and the dihydroxy fatty acids. Four diacylglycerols identified were diOH18:1-diOH18:1, diOH18:2-OH18:1, diOH18:1-OH18:1 and diOH18:0-OH18:1. Eight triacylglycerols identified were diOH18:1-diOH18:1-diOH18:1, diOH18:1-diOH18:1-diOH18:0, diOH18:2-diOH18:1-OH18:1, diOH18:1-diOH18:1-OH18:1, diOH18:1-diOH18:0-OH18:1, diOH18:2-OH18:1-OH18:1, diOH18:1-OH18:1-OH18:1 and diOH18:0-OH18:1-OH18:1. The locations of fatty acids on the glycerol backbone were not determined. The structures of these three newly identified dihydroxy fatty acids were proposed as 11,12-dihydroxy-9-octadecenoic acid, 11,12-dihydroxy-9,13-octadecadienoic acid and 11,12-dihydroxyoctadecanoic acid. These individual acylglycerols were at the levels of about 0.5% or less in castor oil and can be isolated from castor oil or overproduced in a transgenic oil seed plant for future industrial uses.

TI Body weight changes and subsequent lambing rates of western whiteface ewes grazing winter range SO LIVESTOCK SCIENCE LA English DT Article DE Weight loss; Winter grazing; Sheep; Lambing rate ID POLYPAY SHEEP; TARGHEE; RAMBOUILLET; PROLIFICACY; COLUMBIA AB The objective was to describe body weight change (BWC) and subsequent lambing performance of Columbia, Polypay, Rambouillet, and Targhee ewes that grazed shrub-dominated range in winter of 1989, 1990, and 1991. In December (winter), after breeding each year (yr: October to December), ewes were moved to range. Depending upon severity of climatic conditions and vegetation accessibility, ewes grazed winter range for 30 to 60 days (d). Body weights were measured 2 d before grazing commenced (initial) and 2 to 7 d after ewes were transported off range (exit). Total BWC was calculated by subtracting finial BW from initial BW. All data were analyzed within each breed, as repeated measures using mixed models with age and year included in the model. For all breeds, 2-yr-old ewes were lightest going on to winter range and had the lowest lambing rate. Ewes lost weight while grazing winter range, but mature BW, once achieved, was restored annually with the exception of the 7-yr-old Columbia and Targhee ewes. Regardless of breed or age, ewes were able to achieve lambing rates > 1.5 lambs following early- and mid-pregnancy weight loss. Lambing rates were greater in older ewes, which generally experienced substantial negative BWC during winter grazing. Published by Elsevier B.V. C1 [Taylor, J. B.; Moffet, C. A.; Leeds, T.

Adult perch were collected from Lake Erie and body mass, age, gonadosomatic index (I(G)), hepatosomatic index (I(H)), and gene expression for growth hormone (GH), prolactin, somatolactin, insulin-like growth factor Ib (IGF-Ib), estrogen receptor alpha (esr1), estrogen receptor beta a (esr2a), and aromatase (cyp19a1a) were measured. Females had higher body mass, I(H), and liver esr1 mRNA level than males, while males had higher liver IGF-Ib, liver esr2a, and liver cyp19a1a mRNA levels. In both sexes, season had a significant effect on GH and liver IGF-Ib mRNAs with higher levels occurring in spring, which also corresponded with higher liver cyp19a1a mRNA levels. For females, IG, liver esr1, and ovary cyp19a1a mRNA levels were higher in autumn than the spring, and ovary cyp19a1a mRNA levels showed a significant negative correlation with pituitary GH and liver IGF-Ib mRNA levels. The most significant (p <= 0.001) relationships across the parameters measured were positive correlations between liver IGF-Ib and esr2a mRNA levels and liver IGF-Ib and cyp19a1a mRNA levels. This study shows significant effects of season and sex on adult yellow perch endocrine physiology. C1 [Shepherd, B. S.] ARS, Great Lakes WATER Inst, USDA, Milwaukee, WI 53204 USA. [Lynn, S.

In Sub-Saharan Africa, iron deficiency anaemia has largely been attributed to poor infant feeding practices where complementary foods low in iron bioavailability are offered to at-risk infants. Home fortification of complementary foods using micronutrient Sprinkles has been shown to reduce iron deficiency anaemia in many resource-poor settings. In this study, the benefit of using the micronutrient Sprinkles as a home fortificant for some Kenyan complementary foods was assessed using an in vitro Caco-2 cell model. In each case when micronutrient Sprinkles were added to the complementary food, the amount of Caco-2 cell ferritin formation increased. For example, the addition of Sprinkles to corn porridge increased ferritin formation 5-fold from 5.8 to 31.8 ng mg(-1). Therefore, as indicated by the results, micronutrient Sprinkles would be a suitable form of home fortification for Kenyan complementary foods. Their use should be encouraged so as to improve infant feeding practices in Kenya. C1 [Lung'aho, Mercy G.] Cornell Univ, ARS, US Plant Soil & Nutr Lab, USDA,Dept Food Sci, Ithaca, NY 14853 USA.

Chromium's effects in patients at high risk for developing diabetes, especially those with metabolic syndrome, is unknown. The objective of this study was to determine the effects of chromium picolinate (CrPic) on glucose metabolism in patients with metabolic syndrome. Method: A double-blind, placebo-controlled, randomized trial was conducted at a U. S. academic medical center. Sixty three patients with National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III)-defined metabolic syndrome were included. The primary end point was a change in the insulin sensitivity index derived from a frequently sampled intravenous glucose tolerance test. Prespecified secondary end points included changes in other measurements of glucose metabolism, oxidative stress, fasting serum lipids, and high sensitivity C-reactive protein. Results: After 16 weeks of CrPic treatment, there was no significant change in insulin sensitivity index between groups (P = 0.14). However, CrPic increased acute insulin response to glucose (P = 0.02). CrPic had no significant effect on other measures of glucose metabolism, body weight, serum lipids, or measures of inflammation and oxidative stress. Conclusion: CrPic at 1000 mu g/day does not improve key features of the metabolic syndrome in obese nondiabetic patients.

Soil amendments have been used as a means for deliberately altering soil community composition in agricultural soils to enhance plant health. However, little information is available in agricultural or natural soils on how specific carbon compounds or quantities influence soil microbial communities. Streptomyces are important soil saprophytes noted for their ability to produce antibiotics and influence plant health. To explore how specific types and amounts of carbon compounds influence Streptomyces in soil, glucose, cellulose, and lignin were added alone and in combination with six other carbon substrates of varying complexity to mesocosms of native prairie soil for 9 months at amounts equivalent to natural inputs from plants. Estimated culturable population densities, antibiotic inhibitory phenotypes, and resource utilization profiles were examined for Streptomyces communities from each treatment. The type and quantity of carbon compounds influenced densities, proportions, antibiotic phenotypes, and substrate utilization profiles of Streptomyces. Cellulose and lignin inputs produced the largest Streptomyces densities. Also, Streptomyces communities receiving high-resource inputs were more inhibitory whereas those receiving low-resource inputs used substrates more efficiently. Knowledge of how the availability and quantity of particular carbon compounds influences Streptomyces communities and their function, specifically resource use and inhibitory phenotypes, may be helpful in understanding the roles of resource availability in Streptomyces community dynamics and the potential of Streptomyces to suppress pathogens and enhance plant fitness in native and agricultural soils.

Previously, the pstA gene was shown to be involved in the virulence of Mycobacterium avium subspecies paratuberculosis (M. ap), the causative agent of Johne's disease in cattle and a potential risk factor for Crohn's disease. Scanning electron microscopy and colonization levels of the M. ap mutant indicated that the pstA gene significantly contributes to the ability of M. ap to form biofilms. Digital measurements taken during electron microscopy identified a unique morphology for the Delta pstA mutant, which consisted of significantly shorter bacilli than the wild type. Analysis of the lipid profiles of the mycobacterial strains identified a novel lipopeptide that was present in the cell wall extracts of wild-type M. ap, but missing from the Delta pstA mutant. Interestingly, the calf infection model suggested that pstA contributes to intestinal invasion of M. ap. Furthermore, immunoblot analysis of peptides encoded by pstA identified a specific and significant level of immunogenicity. Taken together, our analysis revealed a novel cell wall component that could contribute to biofilm formation and to the virulence and immunogenicity of M. ap. Molecular tools to better control M. ap infections could be developed utilizing the presented findings. (C) 2009 Elsevier Ltd.

TI Robust and highly informative microsatellite-based genetic identity kit for potato SO MOLECULAR BREEDING LA English DT Article DE Microsatellite; Potato; Solanum tuberosum; SSR ID SIMPLE SEQUENCE REPEATS; SOLANUM-TUBEROSUM L.; CULTIVATED POTATO; LINKAGE DISEQUILIBRIUM; EUROPEAN POTATO; LATE BLIGHT; SSRS; RESISTANCE; LANDRACES; DIVERSITY AB The fingerprinting of 742 potato landraces with 51 simple sequence repeat (SSR, or microsatellite) markers resulted in improving a previously constructed potato genetic identity kit. All SSR marker loci were assayed with a collection of highly diverse landraces of all species of cultivated potato with ploidies ranging from diploid to pentaploid. Loci number, amplification reproducibility, and polymorphic information content were recorded. Out of 148 SSR markers of which 30 are new, we identified 58 new SSR marker locations on at least one of three potato genetic linkage maps. These results permitted the selection of a new potato genetic identity kit based on 24 SSR markers with two per chromosome separated by at least 10 cM, single locus, high polymorphic information content, and high quality of amplicons as determined by clarity and reproducibility. The comparison of a similarity matrix of 742 landraces obtained with the 24 SSR markers of the new kit and with the entire dataset of 51 SSR markers showed a high correlation (r = 0.94) by a Mantel test and even higher correlations (r = 0.99) regarding topological comparisons of major branches of a neighbor joining tree. This new potato genetic identity kit is able to discriminate 93.5% of the 742 landraces compared to 98.8% with 51 SSR markers. In addition, we made a marker-specific set of allele size standards that conveniently and unambiguously provide accurate sizing of all alleles of the 24 SSR markers across laboratories and platforms. The new potato genetic identity kit will be of particular utility to standardize the choice and allele sizing of microsatellites in potato and aid in collaborative projects by allowing cumulative analysis of independently generated data.

TI Characteristics and transferability of new apple EST-derived SSRs to other Rosaceae species SO MOLECULAR BREEDING LA English DT Article DE Expressed sequenced tags (EST); Rosaceae; Simple sequence repeats (SSR); Transferability ID PEACH PRUNUS-PERSICA; EXPRESSED SEQUENCE TAGS; X-DOMESTICA BORKH.; MICROSATELLITE MARKERS; GENETIC DIVERSITY; LINKAGE MAP; OCTOPLOID STRAWBERRY; GENOME; FRAGARIA; REPEATS AB Genic microsatellites or simple sequence repeat markers derived from expressed sequence tags (ESTs), referred to as EST-SSRs, are inexpensive to develop, represent transcribed genes, and often have assigned putative function. The large apple (Malus x domestica) EST database (over 300,000 sequences) provides a valuable resource for developing well-characterized DNA molecular markers. In this study, we have investigated the level of transferability of 68 apple EST-SSRs in 50 individual members of the Rosaceae family, representing three genera and 14 species. These representatives included pear (Pyrus communis), apricot (Prunus armeniaca), European plum (P. domestica), Japanese plum (P. salicina), almond (P. dulcis), peach (P. persica), sour cherry (P. cerasus), sweet cherry (P. avium), strawberry (Fragaria vesca, F. moschata, F. virginiana, F. nipponica, and F. pentaphylla), and rose (Rosa hybrida). All 68 primer pairs gave an amplification product when tested on eight apple cultivars, and for most, the genomic DNA-derived amplification product matched the expected size based on EST (in silico) data. When tested across members of the Rosaceae, 75% of these primer pairs produced amplification products. Transferability of apple EST-SSRs across the Rosaceae ranged from 25% in apricot to 59% in the closely related pear. Besides pear, the highest transferability of these apple EST-SSRs, at the genus level, was observed for strawberry and peach/almond, 49 and 38%, respectively. Three markers amplified in at least one genotype within all tested species, while eight additional markers amplified in all species, except for cherry. These 11 markers are deemed good candidates for a widely transferable Rosaceae marker set provided their level of polymorphism is adequate. Overall, these findings suggest that transferability of apple EST-SSRs across Rosaceae is varied, yet valuable, thereby providing additional markers for comparative mapping and for carrying out evolutionary studies.

Mapping of this gene would aid in developing marker-assisted selection protocols to facilitate its introgression into cultivated potato. One RFLP marker and 45 cleaved amplified polymorphic markers (CAPs) markers were used to screen an etuberosum-derived BC3 family segregating for PLRV resistance conferred by Rlr (etb) . Nine markers from linkage group 4 of the tomato map displayed linkage with Rlr (etb) , however, eight additional markers from linkage group 4 that should have been syntenic with Rlr (etb) were not. Instead they segregated with 12 markers previously mapped to linkage group 9 of the tomato map, indicative that chromosomes 4 and 9 of S. etuberosum have translocated regions relative to the potato and tomato genomes. These chromosomal translocations have placed Rlr (etb) beyond the end of the published map of linkage group 4 of tomato with the closest marker, C2_At1g42990, mapping 13.6 cM from Rlr (etb) .

Some fungal genes for trichothecene biosynthesis (Tri genes) are known to be under control of transcription factors encoded by Tri6 and Tri10. Tri6 and Tri10 deletion mutants were constructed in order to discover additional genes regulated by these factors in planta. Both mutants were greatly reduced in pathogenicity and toxin production and these phenotypes were largely restored by genetic complementation with the wild-type gene. Transcript levels for over 200 genes were altered >= twofold for Delta tri6 or Delta tri10 mutants including nearly all known Tri genes. Also reduced were transcript levels for enzymes in the isoprenoid biosynthetic pathway leading to farnesyl pyrophosphate, the immediate molecular precursor of trichothecenes. DNA sequences 5' to isoprenoid biosynthetic genes were enriched for the Tri6p DNA binding motif, YNAGGCC, in F. graminearum but not in related species that do not produce trichothecenes. To determine the effect of trichothecene metabolites on gene expression, cultures were treated with trichodiene, the first metabolic intermediate specific to the trichothecene biosynthetic pathway. A total of 153 genes were upregulated by added trichodiene and were significantly enriched for genes likely involved in cellular transport. Differentially regulated genes will be targeted for functional analysis to discover additional factors involved in toxin biosynthesis, toxin resistance and pathogenesis.

Juvenile Florida pompano (mean weight +/- SE = 259.0 +/- 3.0 g) were stocked into two tanks from each of four separate RASs at an initial nominal density of 6.5 (low density) or 13.0 kg/m(3) (high density), equivalent to 200 and 400 fish/tank, respectively. After stocking, fish were fed a 4.7-mm, floating pelleted diet (50% protein, 14% lipid) twice daily at a targeted daily feed rate of 3% body weight per day. At stocking and at 3-week intervals thereafter, 10% of the fish Population of each tank was sampled to determine production characteristics, including mean weight, weight gain, specific growth rate, absolute growth rate (AGR), feed conversion efficiency (FCE), biomass, and survival. At termination, fish in all tanks were harvested to determine production characteristics and samples were obtained to determine whole-body composition, energy retention, protein efficiency ratio (PER), protein productive value (PPV), hepatosomatic index, gonadosomatic index, and fillet yield. Results indicated that final weight (570.0 g), weight gain (312.7 g), AGR (2.8 g/d), FCE (25.5%), PER (0.54), and PPV (11.5%) of fish reared at high density were significantly lower than those of fish reared at low density. No differences were observed between density treatments with respect to other measured variables. Additional studies must focus on the development of finishing diets for final stages of Florida pompano production to increase FCE and to determine optimal rearing densities. In addition, research to evaluate the potential of rearing pompano in RASs at salinities lower than 5%omicron, perhaps through environmental or dietary enhancement of critical ions, is warranted.

Although electrofishing is a commonly used technique to capture fish and some invertebrates in freshwater, applications in marine systems are limited due to the high conductivity of the water medium. Experiments conducted in aquaria showed that burrowing bay ghost shrimp Neotrypaea californiensis responded best (forced swimming with directed movement) to a pulsed DC waveform with optimal parameter settings of 1 V/cm, a frequency of 2 Hz, and a pulse width of 0.001-0.005 s. Unfortunately, when bay ghost shrimp were allowed to burrow into the substrate, they displayed a similar reaction but moved towards the bottom of their burrows, thus ruling out the envisioned use of this technique to attract them to the surface for capture. In experiments designed to induce mortality, it was possible to achieve paralysis or tetany by use of higher power with DC, pulsed DC, and AC, but the animals recovered unless (1) exposure time exceeded 60-100 s and (2) voltage exceeded 100 V (5 V/cm), frequency exceeded 120 Hz (pulsed DC), or both. These sustained levels would be difficult to achieve in the field due to the substrate, depth of the shrimp burrows, and high power necessary to obtain adequate field strength.

TI Constructed Microhabitat Bundles for Sampling Fishes and Crayfishes in Coastal Plain Streams SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID PREDATOR-PREY INTERACTION; WOODY DEBRIS; LARGEMOUTH BASS; SOUTHERN ONTARIO; LOWLAND RIVERS; PIRATE PERCH; HABITAT USE; COMMUNITY; ASSEMBLAGES; BEHAVIOR AB We investigated fish and crayfish use of standardized, constructed microhabitats (bundles) in three northern Mississippi streams. Cypress Creek and the Little Tallahatchie Canal were channelized and incised and had little woody cover; Puskus Creek was unchannelized and unincised and had abundant woody cover. We constructed three types of bundles (cane, leaf, and string) and deployed replicates of each in winter and spring. Occupancy of bundles by fish and crayfish was high and included 32 fish species representing eight families. Fish abundance did not differ among bundle types or between channel positions (bank or midchannel), but abundance of crayfish showed mixed responses to bundle type and position. Fish and crayfish use of bundles was higher in the channelized streams (89% occupied) than in the unchannelized stream (49% occupied). Furthermore, after a winter storm, fish use increased in the channelized streams but not in the unchannelized stream. Bundles yielded abundance estimates with modest to poor precision (40-73% for fish: 37-125% for crayfish); about 110-140 bundles would be necessary to consistently achieve precision of 30%. Bundles were effective for sampling a subset of fish assemblages (e.g., darters Etheostoma spp. and Percina spp. and madtoms Noturus spp.), but other fish species were conspicuously underrepresented or absent in our samples relative to sampling by electrofishing and seine (e.g., open-water species and large individuals). Nevertheless, microhabitat bundles can be effective for sampling small fish and crayfish that associate with woody cover and that are difficult to sample with conventional methods.

TI Cattle Trampling of Simulated Bull Trout Redds SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID BROOK TROUT; SITE SELECTION; TEMPERATURE; COMPETITION AB Listing of the bull trout Salvelinus confluentus under the Endangered Species Act and concerns over livestock stepping on bull trout redds have led many U.S. Department of Agriculture Forest Service managers to remove livestock from bull trout spawning areas once spawning begins. While this policy has extensive ramifications for livestock producers who graze their cattle on national forests, a lack of data precludes evaluation of the benefit of livestock removal to bull trout populations. To fill this information gap, we assessed the probability that cattle would step on simulated bull trout redds in grazing allotments within the Little Lost River drainage in Idaho. Bull trout redds were simulated using clusters of clay shooting targets. Simulated redds were placed in streams within three grazing pastures where bull trout have historically spawned or currently spawn. During the 14-21-d grazing period, 15-83% of the simulated redds were affected by trampling. When the control period was standardized to the same time period as the treatment, cattle were found to be responsible for affecting 12-78% of simulated redds and breaking 6-49% of the clay targets. Impacts were higher in pastures where cattle stocking intensity was higher, but impacts were also determined by site conditions adjacent to the simulated redds.

We sought to measure the influence of deposited fine sediment on the survival and growth of juvenile rainbow trout Oncorhynchus mykiss (106-130 mm fork length) using a field experiment that included 18 enclosures in riffles of a small northwestern California stream. The experiment included six replicates of three levels of deposited fine sediment (low, background, and high) that embedded riffle cobbles at 0, 50, and 100%. respectively. Only I of 12 fish survived in high-sediment enclosures, while survival of fish in low- and background-sediment treatments equaled or exceeded 50%. Low- and background-sediment treatments could be distinguished from each other by a difference in fish growth: fish in the low-sediment treatment gained mass, on average, while all surviving fish in the background-sediment treatment lost mass. In addition to providing relatively high survival and growth benefits for juvenile rainbow trout. low-sediment experimental unit,; were colonized at significantly higher rates by other vertebrates, particularly coastal giant salamanders Dicamptodon tenebrosus. The amount of stored fine sediment in small streams may substantially influence the total amount of habitat available to vertebrates at the watershed scale.

TI Folate, cancer risk, and the Greek god, Proteus: a tale of two chameleons SO NUTRITION REVIEWS LA English DT Review DE colorectal cancer; folate; folic acid fortification ID FOLIC-ACID FORTIFICATION; BREAST-CANCER; DIETARY-FOLATE; COLORECTAL-CANCER; CARDIOVASCULAR EVENTS; TOTAL HOMOCYSTEINE; PLASMA FOLATE; B-VITAMINS; TRIAL; ADENOMAS AB Evidence indicates that an abundant intake of foodstuffs rich in folate conveys protection against the development of colorectal cancer, and perhaps some other common cancers as well. The issue is complex, however, since some observations in animal and human studies demonstrate that an overly abundant intake of folate among those who harbor existing foci of neoplasia might instead produce a paradoxical promotion of tumorigenesis. The pharmaceutical form of the vitamin, folic acid, might affect the process in a manner that is distinct from natural forms of the vitamin, although this remains a speculative concept. Our limited understanding of this complex relationship is impeding efforts to move ahead with widespread folic acid fortification, but this delay may be necessary to ensure that such programs are instituted in a safe manner.

Transgenic approaches involving the expression of viral genes are being developed to provide protection for plants against viral diseases. The purpose of this study was to develop double transgenic plants of potato using PLRV replicase and PVY coat protein genes tandemly placed in a single T-DNA transformant through Agrobacterium-mediated transformation. A total of 17 lines of putative transformants of potato cv. Desiree were generated from kanamycine resistant calli originated from co-inoculation of separate Agrobacterium cultures containing PVY CP and PLRV replicase genes. Shoots were excised and cultured onto shoot medium containing 250mg/L cefotaxime and 50mg/L kanamycin sulfate in test tubes. Polymerase chain reaction (PCR) analysis was conducted of 39 plants of 16 transformed lines using primers each of PVY CP and PLRV-replicase genes; 10 plants of 8 lines and 7 plants of 6 lines showed presence of of PVY CP and PLRV-replicase genes, respectively. However, 22 plants of 14 lines harbored both PVY-CP (508bp) and PLRV-replicase (449bp) genes. Sixteen plants of 11 double transgenic lines that showed high level of expression of both PLRV-replicase and PVY-CP genes. Transformants and control standards were exposed to field virus infection augmented by placement of aphids on Datura leaves infected with PLRV. Two clones (Des (CP+LR) 9.1 and Des (CP + LR) 9.2) showed incidence of infection statistically lower than the lowest infection of one of the standards (Ranger). The Monsanto clone (21-350) showed no infection. The two resistant clones may be identical as they were derived from the same callus. C1 [Thomas, P. E.; Crosslin, J. M.; Brown, C.

It has recently been suggested as a means to control infestations of Ichthyophthirius multifiliis. The purpose of this study was to determine the acute toxicity of two products containing 4.5% and 40% PAA to I. multifiliis theronts from two geographically separate isolates. Theronts were exposed to concentrations of PAA in 96-well plates containing groundwater at 23A degrees C. Acute toxicity was observed over a 4-h period. No significant difference in the median lethal concentration (LC(50)) estimates was evident between the two isolates at 4 h with the 4.5% PAA product (0.146 versus 0.108 mg/l PAA), while there was a statistical difference between the 4 h LC(50) with the 40% PAA product (0.274 versus 0.158 mg/l PAA). These results suggest that PAA is toxic to I. multifiliis theronts at low concentrations and that one of the isolates was more resistant to this compound.

TI Surface-applied insecticide treatments for quarantine control of Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), larvae in field-grown nursery plants SO PEST MANAGEMENT SCIENCE LA English DT Article DE Popillia japonica; nursery; neonicotinoid; scarab; ornamentals ID WHITE GRUBS COLEOPTERA; CHAFER COLEOPTERA; TURFGRASS; CHLORPYRIFOS; OVIPOSITION; MANAGEMENT; RESISTANCE; BEHAVIOR AB BACKGROUND: Japanese beetles, Popillia japonica Newman, are a quarantine challenge for nursery shipments from infested to non-infested states. Marathon (imidacloprid) and Discus (imidacloprid + cyfluthrin) are approved preharvest nursery treatments (US Domestic Japanese Beetle Harmonization Plan; DJHP). This study evaluated approved and non-approved (acephate, carbaryl, clothianidin, dinotefuran, halofenozide, thiamethoxam, trichlorfon) preharvest treatments, optimal rates (labeled 1 x, 0.3-0.75 x or 2-3 x) and optimal timings (June, July, August and September) to control early-instar (grubs) P. japonica in field nurseries. RESULTS: Most insecticides effectively reduced grub densities, except for acephate, carbaryl and trichlorfon. Clothianidin, thiamethoxam and halofenozide provided grub control equivalent to DJHP standards during most years. Across all test years and timings, percentage grub reductions were: Marathon (1 x: 59.2-100; 3 x: 78.9-100), Discus (11 x: 60.7-100), clothianidin 0 x: 96.1-100; 3 x: 97.4-100), thiamethoxam (1 x: 75.0-100; 3 x: 80.0-100), halofenozide (1 x: 70.0-100; 3 x: 90.0-100) and dinotefuran (1 x: 13.2-88.2; 3 x: 71.1-93.4). CONCLUSIONS: July application was more consistent and effective than other timings, and higher rates (2 x and 3 x) did not generally improve grub control. Overall, clothianidin, thiamethoxam and halofenozide (and dinotefuran applied in August) were equivalent to current DJHP standards. These insecticides may be suitable for DJHP Category 2 states, potentially lowering grower costs.

Owing to the high insecticidal selection pressures in this region, monitoring of Bt resistance in H. armigera is necessary so that proactive actions can be implemented before field control measures fail. From 2003 to 2005, an F-2 screen was conducted in order to monitor Bt resistance in H. armigera populations collected from this area. RESULTS: The F-2 screen showed that 15 out of 278 isofemale lines carried resistance alleles to Bt cotton. The resistance allele frequency in field populations of H. armigera ranged from 0.0119 to 0.0297, with an overall frequency of 0.0146 and a 95% confidence interval of 0.0084-0.0225 for the 3 year period. This value is greater than the value reported from 1999 (P < 0.05). CONCLUSION: A fluctuating but overall increase in resistance allele frequency was detected in the field populations of H. armigera in Qiuxian County from 1999 to 2005. To prevent further increases in Bt resistance frequency in this pest, it is necessary to introduce Bt cotton expressing multiple Bt toxins and integrate this technology with other tactics for management of this key pest.

This study was conducted to evaluate airborne ATSA+ hyperspectral imagery and image transformation and classification techniques for mapping black mangrove populations on the south Texas Gulf coast. AISA+ hyperspectral imagery was acquired from two study sites, and both minimum noise fraction (MNF) and inverse MNF transforms were performed. Four classification methods, including minimum distance, Mahalanobis distance, maximum likelihood, and spectral angle mapper (SAM), were applied to the noise-reduced hyperspectral imagery and to the band-reduced MNF imagery for distinguishing black mangrove from associated plant species and other cover types, Accuracy assessment showed that overall accuracy varied from 84 percent to 95 percent for site 1 and from 69 percent to 91 percent for site 2 among the eight classifications for each site. The MNF images provided similar or better classification results compared with the hyperspectral images among the four classifiers. Kappa analysis showed that there were no significant differences among the four classifiers with the MNF imagery, though maximum likelihood provided excellent overall and class accuracies for both sites. Producer's and user's accuracies for black mangrove were 91 percent and 94 percent, respectively, for site 1 and both 91 percent for site 2 based on maximum likelihood applied to the MNF imagery. These results indicate that airborne hyperspectral imagery combined with image transformation and classification techniques can be a useful tool for monitoring and mapping black mangrove distributions in coastal environments.

We examined changes in the proteome of potato leaves in response to inoculation with P. infestans. A nearly isogenic system comprised of susceptible Solanum tuberosum cultivar 'Katahdin' and resistant transgenic potato (cv. 'Katahdin') carrying a single copy of RB was utilized for this study. Comparative proteomic analysis revealed the presence of only 12 protein spots with a significant difference (>= twofold) in relative abundance in resistant and susceptible potato plants after inoculation with P. infestans. Five out of the 12 identified proteins have putative roles in photosynthesis and stress responses. Silencing of these genes in Nicotiana benthamiana had no impact on RB-mediated induction of the hypersensitive response (HR). However, we found that silencing of molecular chaperone HSP90 led to the inability of RB to induce the HR after recognition of the P. infestans effector IpiO in planta. Published by Elsevier Ltd.

The effects of post-anthesis environmental conditions on FHB are poorly understood. We performed a field experiment at Kinston, NC, to explore the effects of increasing duration of post-anthesis moisture on disease incidence, disease severity, Fusarium-damaged kernels (FDK), percent infected kernels, and DON. The experiment had a split-plot design, and one trial was conducted in each of two successive years. Main plots consisted of post-anthesis mist durations of 0, 10, 20, or 30 days. Subplots were of eight cultivars in the first year and seven in the second year, two being susceptible to FHB and the remainder each with varying degrees of apparent type I and type II resistance. Plots were inoculated by spraying Fusarium graminearum macroconidia at mid-anthesis. Averaging across years and cultivars, 10 or 20 days of post-anthesis mist had the same effect (P >= 0.198) and were associated with an approximately fourfold increase in mean disease incidence and eightfold increase in disease severity compared with 0 days of mist (P <= 0.0002). In both years, mean FDK percentages at 0 and 10 days post-anthesis mist were the same and significantly lower than FDK percentages under 20 or 30 days of post-anthesis mist. Mist duration had a significant effect on percent kernels infected with Fusarium spp. as detected by a selective medium assay of 2007 samples. Averaging across all cultivars, in both years, DON levels increased significantly for 10 days compared with 0 days of mist, and increased again with 20 days of mist (P <= 0.04). This is the first investigation to show that extended post-flowering moisture can have a significant enhancing effect on FHB, FDK, DON, and percent infected kernels of wheat. For all disease and toxin assays, cultivar rankings were significantly noncorrelated among mist durations in at least 1 year, suggesting that FHB screening programs might rank genotypes differently under extended post-anthesis moisture than without it. Our findings also imply that accurate forecasts of DON in small grains must take account of post-anthesis weather conditions.

Rain samples were screened for Phakopsora pachyrhizi (causal agent of soybean rust) DNA using a nested real-time polymerase chain reaction assay. Over this time frame, P. pachyrhizi spores were detected in every state in the study, but more frequently in states along the Gulf and Atlantic coasts and along the Ohio River Valley westward to Kansas. A bimodal temporal distribution of samples testing positive for P. pachyrhizi was found in both years. However, there was a greater than threefold increase in the number of samples testing positive for P. pachyrhizi in 2006 compared with 2005, with the most significant increase in August. There was also an increase in the average number of spores per sample in 2006 relative to 2005. Sequence analysis of a subset of positive samples was used to validate the assay results. From the sequence analysis, two reliable polymorphic regions were found, resulting in six distinct genotypes. One genotype was found in 56% of the samples tested, whereas the other genotypes were found less frequently. C1 [Barnes, C. W.; Szabo, L. J.] USDA ARS, Cereal Dis Lab, Washington, DC 20250 USA.

To determine the geographical distribution of soybean rust in Nigeria, soybean fields were surveyed in the Derived Savanna (DS), Northern Guinea Savanna (NGS), and Southern Guinea Savanna (SGS) agroecological zones in Nigeria between 2004 and 2006. Disease severity in each zone was determined and analyzed using geostatistics. Prevalence of infected fields and disease severity in surveyed fields were significantly (P < 0.05) different between geographical zones with both variables being higher in the DS zone than in either NGS or SGS zones. Geostatistical analysis indicated that the spatial influence of disease severity at one location on severity at other locations was between 75 and 120 km. An exponential model best described the relationship between semivariance and lag distance when rust severity was high. Spatial interpolation of rust severity showed that locations in the DS zone were more conducive for the rust epidemic compared to areas in the NGS zone. In the 2005 survey, 116 purified isolates were established in culture on detached soybean leaves. To establish the nature of pathogenic variation in P. pachyrhizi, a set of four soybean accessions with Rpp(1), Rpp(2), Rpp(3), and Rpp(4) resistance genes, two highly resistant and two highly susceptible genotypes were inoculated with single uredinial isolates. Principal component analysis on the number of uredinia per square centimeter of leaf tissue for 116 isolates indicated that an adequate summary of pathogenic variation was obtained using only four genotypes. Of these four, PI 459025B (with Rpp(4) gene) and TGx 1485-1D had the lowest and highest number of uredinia per square centimeter, respectively. Based on cluster analysis of the number of uredinia per square centimeter, seven pathotype clusters were determined. Isolates in cluster III were the most virulent, while those in cluster IV were the least virulent. Shannon's index (H) revealed a more diverse pathogen population in the DS zone (H = 1.21) compared to the rust population in SGS and NGS with H values of 1.08 and 0.91, respectively. This work will be useful in breeding and management of soybean rust by facilitating identification of resistant genotypes and targeting cultivars with specific resistance to match prevailing P. pachyrhizi pathotypes in a given geographical zone.

Three CTB disease stages were modeled using recurrent event analysis. Wound inoculated stems were observed at regular intervals for appearance of disease symptoms. Survival times (time from inoculation until symptom appearance) for the three disease stages (mild, moderate, and severe) were regressed against stem diameter, monthly mean hours/day within a specified temperature range (15 to 30 degrees C), and season (spring, summer, fall, and winter). For all three CTB disease stages, stem diameter had a protective effect on survival times, while monthly mean hours/day in the specified temperature range and warmer seasons were risk factors. Based upon median ratios, the mild disease stage developed 2 to 3 times faster in spring, summer, and fall than in winter. Similarly, moderate and severe disease stages developed 2 to 2.5 times faster. For all three disease stages, seasonal differences in stage development were smaller among fall, spring, and summer, varying from 1 to 1.6 times faster. Recurrent event modeling of CTB progression provides knowledge concerning developmental expression of this disease, information necessary for creating a comprehensive, integrated disease management program.

TI Evaluation of Molecular Markers for Phytophthora ramorum Detection and Identification: Testing for Specificity Using a Standardized Library of Isolates SO PHYTOPATHOLOGY LA English DT Article ID CHAIN-REACTION ASSAY; SUDDEN OAK DEATH; REAL-TIME PCR; EUROPEAN POPULATIONS; RIBOSOMAL DNA; QUANTIFICATION; CALIFORNIA; POLYMORPHISM; DIAGNOSIS; AMERICAN AB Given the importance of Phytophthora ramorum from a regulatory standpoint, it is imperative that molecular markers for pathogen detection are fully tested to evaluate their specificity in detection of the pathogen. In an effort to evaluate 11 reported diagnostic techniques, we assembled a standardized DNA library using accessions from the World Phytophthora Genetic Resource Collection for 315 isolates representing 60 described Phytophthora spp. as well as 11 taxonomically unclassified isolates. These were sent blind to collaborators in seven laboratories to evaluate published diagnostic procedures using conventional (based on internal transcribed spacer [ITS] and cytochrome oxidase gene [cox]1 and 2 spacer regions) and real-time polymerase chain reaction (based on ITS and cox1 and 2 spacer regions as well as beta-tubulin and elicitin genes). Single-strand conformation polymorphism (SSCP) analysis using an automated sequencer for data collection was also evaluated for identification of all species tested. In general, the procedures worked well, with varying levels of specificity observed among the different techniques. With few exceptions, all assays correctly identified all isolates of P. ramorum and low levels of false positives were observed for the mitochondrial cox spacer markers and most of the real-time assays based on nuclear markers (diagnostic specificity between 96.9 and 100%). The highest level of false positives was obtained with the conventional nested ITS procedure; however, this technique is not stand-alone and is used in conjunction with two other assays for diagnostic purposes. The results indicated that using multiple assays improved the accuracy of the results compared with looking at a single assay alone, in particular when the markers represented different genetic loci. The SSCP procedure accurately identified P. ramorum and was helpful in classification of a number of isolates to a species level. With one exception, all procedures accurately identified P. ramorum in blind evaluations of 60 field samples that included examples of plant infection by 11 other Phytophthora spp. The SSCP analysis identified eight of these species, with three identified to a species group.

TI Variation in Tomato spotted wilt virus Titer in Frankliniella occidentalis and Its Association with Frequency of Transmission SO PHYTOPATHOLOGY LA English DT Article DE Bunyaviridae; Thysanoptera; virus-vector interactions ID REAL-TIME PCR; VECTOR COMPETENCE; RT-PCR; RNA SEGMENT; S-RNA; TOSPOVIRUS; THRIPS; EPIDEMIOLOGY; YELLOW; QUANTIFICATION AB Tomato spotted wilt virus (TSWV) is transmitted in a persistent propagative manner by Frankliniella occidentalis, the western flower thrips. While it is well established that vector competence depends on TSWV acquisition by young larvae and virus replication within the insect, the biological factors associated with frequency of transmission have not been well characterized. We hypothesized that the number of transmission events by a single adult thrips is determined, in part, by the amount of virus harbored (titer) by the insect. Transmission time-course experiments were conducted using a leaf disk assay to determine the efficiency and frequency of TSWV transmission following 2-day inoculation access periods (IAPs). Virus titer in individual adult thrips was determined by real-time quantitative reverse transcriptase-PCR (qRT-PCR) at the end of the experiments. On average, 59% of adults transmitted the virus during the first IAP (2 to 3 days post adult-eclosion). Male thrips were more efficient at transmitting TSWV multiple times compared with female thrips of the same cohort. However, females harbored two to three times more copies of TSWV-N RNA per insect, indicating that factors other than absolute virus titer in the insect contribute to a successful transmission event. Examination of virus titer in individual insects at the end of the third IAP (7 days post adult-eclosion) revealed significant and consistent positive associations between frequency of transmission and virus titer. Our data support the hypothesis that a viruliferous thrips is more likely to transmit multiple times if it harbors a high titer of virus. This quantitative relationship provides new insights into the biological parameters that may influence the spread of TSWV by thrips.

TI Molecular Characterization of Citrus tatter leaf virus Historically Associated with Meyer Lemon Trees: Complete Genome Sequence and Development of Biologically Active In Vitro Transcripts SO PHYTOPATHOLOGY LA English DT Article ID NUCLEOTIDE-SEQUENCE; FAMILY FLEXIVIRIDAE; APPLE; CAPILLOVIRUS; ALIGNMENT; PEAR AB Citrus tatter leaf virus isolated from Meyer lemon trees (CTLV-ML) from California and Florida induces bud union incompatibility of citrus trees grafted on the widely used trifoliate and trifoliate hybrid rootstocks. The complete genome sequence of CTLV-ML was determined to be 6,495 nucleotides (nts), with two overlapping open reading frames (ORFs) and a poly (A) tail at the 3' end. The genome organization is similar to other capilloviruses, with ORF1 (nts 37 to 6,354) encoding a putative 242-kDa polyprotein which contains replication-associated domains plus a coat protein (CP), and ORF2 (nts 4,788 to 5,750), which is located within ORF1 in a different reading frame and encodes a putative movement protein. Although the proteins encoded by CTLV-ML possesses 84 to 96% amino acid sequence identity with strains of Apple stem grooving virus (ASGV), we observed two strikingly different regions in ORF1: variable region I (amino acids 532 to 570) and variable region II (amino acids 1,583 to 1,868), with only 15 to 18 and 56 to 62% identities, respectively, with the corresponding regions of ASGV strains. Conditions for a herbaceous systemic assay host were optimized in which the wild-type virus induced systemic infection in Phaseolus vulgaris cv. Light Red Kidney (LRK) bean plants at 19 or 22 degrees C but not at higher temperatures. In vitro transcripts generated from full-length cDNA clones induced systemic symptoms on LRK bean plants similar to that of the wild-type virus. Replication of the recombinant virus was confirmed by hybridization of a 5' positive-stranded RNA-specific probe to a genome-sized RNA and by reverse-transcription polymerase chain reaction.

TI Quantitative Trait Locus Mapping of Increased Fusarium Head Blight Susceptibility Associated with a Wild Emmer Wheat Chromosome SO PHYTOPATHOLOGY LA English DT Article ID TETRAPLOID WHEAT; RUST RESISTANCE; BREAD WHEAT; QTL; MARKERS; GENES; SCAB; MAP; NURSERIES AB Chromosome 2A of wild emmer wheat (Triticum turgidum var. dicoccoides) genotype Israel A increases Fusarium head blight (FHB) severity when present in durum wheat (T. turgidum var. durum) cv. Langdon (LDN). The goal of this study was to identify regions of Israel A chromosome 2A associated with this difference in resistance. A recombinant inbred chromosome line population (RICL) from a cross between LDN and the LDN-Israel A chromosome 2A substitution line [LDN(DIC-2A)] was employed for analysis. Three greenhouse FHB evaluations were completed on the RICL to obtain phenotypic data on variation for FHB resistance, and a simple sequence repeat (SSR)-based molecular map of chromosome 2A was developed. Quantitative trait locus (QTL) mapping identified a region on the long arm of chromosome 2A that was associated with FHB resistance in each independent FHB evaluation. Depending on the evaluation, the single best SSR marker in this region accounted for between 21 and 26% of the variation for FHB resistance, with the Israel A marker alleles associated with increased FHB susceptibility. The single best markers from each evaluation reside within an interval of approximately 22 cM. This study identifies one or more new QTL on chromosome 2A in tetraploid wheat that can contribute to significant variation in FHB resistance.

The efficacy of fungicide mixtures consisting of fenamidone + mancozeb and propamocarb HCL + mancozeb at various rates and in spray regimes containing metalaxyl and mancozeb was evaluated for late blight control (US-1) at four locations in Kenya. Propamocarb HCL + mancozeb significantly (P < 0.05) reduced foliar blight compared with mancozeb and the untreated control under moderate to severe disease pressure. Disease severity was significantly lower following application of propamocarb HCL + mancozeb at a rate of 4L ha(-1) than at rates of 2L and 3L ha(-1) in 1999 and 2000, but it was not significantly lower following applications at a rate of 3L ha(-1) in 2000 and 2001. There were no significant differences in mean final late blight score among the three rates of 0.9, 1.0 and 1.1 kg ha(-1) of fenamidone + mancozeb. All fungicide mixtures and application sequences significantly reduced the area under the disease progress curve and final late blight scores as compared with the unprotected control. Total and marketable tuber yield significantly (P < 0.05) increased in all fungicide-treated plots. C1 [Olanya, O. M.] USDA ARS, Soil & Water Lab, Orono, ME 04469 USA. [Muchiri, F. N.; Narla, R.

TI Phosphorus runoff from a phosphorus deficient soil under common bean (Phaseolus vulgaris L.) and soybean (Glycine max L.) genotypes with contrasting root architecture SO PLANT AND SOIL LA English DT Article DE Phosphorus; Runoff; Erosion; Root architecture; Common bean ID MAIZE ZEA-MAYS; CONCENTRATED FLOW; HYDRAULIC-PROPERTIES; AGGREGATE STABILITY; SIMULATED RAINFALL; SPLASH DETACHMENT; NUTRIENT-UPTAKE; PLANT-ROOTS; EROSION; WATER AB The selection and breeding of crop genotypes with root traits that improve soil resource extraction is a promising avenue to improved nutrient and water use efficiency in low-input farming systems. Such genotypes may accelerate nutrient extraction ("nutrient mining"), but may also reduce nutrient loss via soil erosion by producing greater shoot biomass and by direct effects of root traits on aggregate formation and water infiltration. Little is known about the effects of root architecture on phosphorus (P) runoff and soil erosion, and the relative importance of root and shoot traits on runoff P loss has not been determined. Four genotypes of common bean (Phaseolus vulgaris L.) and two genotypes of soybean (Glycine max) selected for contrasting root architecture were grown in a low P soil (Aquic Fragiudult, < 20 mg kg(-1) Mehlich-3 P, 3% slope) and subjected to rainfall-runoff experiments with and without shoot removal. Plots with intact shoots had significantly lower runoff volumes (1.3-7.6 mm) and total P loads in runoff (0.005-0.32 kg ha(-1)) than plots with shoots removed (7.0-16.8 mm; 0.025-1.95 kg ha(-1)). Dissolved reactive P leached from plant material did not contribute significantly to P loss in runoff. Total root length acquired from soil cores differed significantly among genotypes. Root length densities in the upper 15 cm of soil mid-way between rows were less than 4.0 cm cm(-3) and variation in root length density was not correlated with runoff or P loss. Root length density also did not affect rainfall infiltration or surface runoff volume. We conclude that for annual dicotyledonous crops such as bean and soybean with relatively low root length densities, root traits have little direct effect on soil erosion.

It has been shown previously that root tonoplast vesicles isolated from plants expressing these genes, directed by root-selective promoters, show enhanced Cd transport activity, and young plants show enhanced root Cd accumulation when grown in solution culture containing 0.02 mu m Cd, a moderate Cd dose. In this article, we present results which show that the lower leaves of mature plants expressing AtCAX2 or AtCAX4, under the control of two different root-selective promoters, accumulate 15%-25% less lamina Cd than control plants when grown in the field (3 years, three different collection methods). Reciprocal grafting experiments of AtCAX2 shoots onto control roots (and vice versa), grown in solution culture with 0.005 mu m Cd, indicated that the root controls Cd translocation and accumulation in the shoot in control and AtCAX2 and AtCAX4 tobacco plants exposed to low Cd concentration. The results are consistent with a model in which supplementation of Cd/H antiporter activity in root cell tonoplasts enhances root Cd sequestration, resulting in decreased translocation of Cd to the shoot of field-grown plants. These results suggest that human Cd intake from food and tobacco use could be reduced via the enhancement of root vacuolar sequestration of this pollutant.

These compounds are biosynthesized through the action of the enzyme hydroxycinnamoyl CoA: hydroxyanthranilate N-hydroxycinnamoyl transferase (HHT) which catalyzes the condensation of one of several cinnamate CoA thioesters with the amine functionality of anthranilic acid, 4-hydroxy- or 5-hydroxy-anthranilic acid. In oat leaf tissue the biosynthesis of avenanthramides appears to result from elicitation by fungal infection. Here we demonstrate the biosynthesis of several avenanthramides in suspension cultures of oat apical meristem callus tissue. This phenomenon appears as a generalized pathogen response, evidenced by the production of PR-1 mRNA, in response to elicitation with chitin (poly-N-acetyl glucosamine). The suspension cultures also produce relatively large quantities of avnA and G in response to chitin elicitation. Under certain culture conditions avnB and C are also produced as well as three additional metabolites tentatively identified as avnH, O and R. These findings portend the utility of oat suspension culture as a tool for more detailed investigation of the mechanisms triggering their biosynthesis as well as the factors dictating the particular types of avenanthramides biosynthesized.

Numerous race-specific (Pc) genes for crown rust have been found in Avena spp. but this type of resistance has not been durable when used in oat cultivars. Increasing diversity for resistance within a crop by the use of multiline cultivars or varietal mixtures has been proposed its a means of achieving durable resistance to highly variable pathogens such as P. coronata f. Sp. Multiline cv. E77 was evaluated over multiple seasons in the University of Minnesota buckthorn nursery in St. Paul. Buckthorn (Rhamnus cathartica, the alternate host of P. coronata) Supports a sexually recombining, highly diverse crown rust population in the St. Paul nursery. Crown rust severity on flap! leaves was measured multiple times on E77 and its 10 component lines during grain filling. Single-uredinioispore isolates taken from crown rust samples during early stages of the epidemic and at the end of the epidemic were tested for virulence on the 10 component lines of E77 in greenhouse seedling tests, Crown rust development was reduced in E77 compared with the weighted mean of the component lines at all stages of the crown rust epidemics. The mean virulence of single urediniospore isolates tended to increase late in the epidemic on E77. These data suggest that multilines may select for complex virulence or "super races" and any resistance effect may not be durable. C1 USDA ARS, Cereal Dis Lab, St Paul, MN 55108 USA.

TI Broad-Spectrum Resistance to Crown Rust, Puccinia coronata f. sp avenae, in Accessions of the Tetraploid Slender Oat, Avena barbata SO PLANT DISEASE LA English DT Article ID MILDEW RESISTANCE; SATIVA; GENE; WILD AB The use of race-specific seedling genes for resistance has been the primary means of controlling clown rust of oat (Puccinia coronata). As resistance genes from hexaploid cultivated oat, Avena sativa and, later. the wild hexaploid animated oat, A, sterilis, were deployed in oat cultivars, corresponding virulence in the crown rust population increased rapidly, such that the effective lifespan of a resistant cultivar in the United States is now 5 years or less, Introgression of resistance genes from diploid and tetraploid Avena spp. into hexaploid oat has been difficult due to differences in ploidy levels and the lack of homology of chromosomes between the two species. The wild tetraploid slendet oat, A. barbata, has been a source of powdery mildew and stein rust resistance in cultivated oat but has largely been unexploited for crown rust resistance. In total, 359 accessions of A. barbata from the National Small Grains Collection were evaluated in seedling greenhouse tests. Of these accessions, 39% were at least moderately resistant when inoculated with a crown rust race with low virulence (DBBC). When tested further with,I highly diverse bulk inoculum from the 2006 and 2007 St. Paul buckthorn nursery, 49 accessions (approximately 13%) were resistant. Many of these accessions were heterogeneous in reaction, but two accessions (PI320588 from Israel and PI337893 from Italy) were highly resistant (immune) and two others (PI337986 from Italy and PI367293 from Spain) consistently produced resistant reactions (chlorotic flecks) in all tests. Resistant accessions were found from throughout much of the natural range of A. barbata. Crosses of some of the better accessions have been made to cultivated oat.

TI Detection of Virulence to Resistance Gene Sr36 Within the TTKS Race Lineage of Puccinia graminis f. sp tritici SO PLANT DISEASE LA English DT Article ID MARKERS; WHEAT AB The stem rust resistance gene Sr36 confers it near-immune resistance reaction to many races of Puccinia graminis f. sp. tritici and is highly effective against race TTKSK (syn. Ug99), which possesses unusually broad virulence combinations. Because this gene is widely used in United States soft winter wheat germplasm and cultivars, it has been considered to be an important source of resistance to TTKSK. In 2007, moderately susceptible infection responses were observed on wheat lines and cultivars carrying Sr36 in a field screening nursery for stem rust at Njoro, Kenya. We derived 19 single-pustule isolates from stem rust samples collected from the 2007 Njoro nursery. The isolates were evaluated for virulence oil 20 North American stem rust differential lines and on wheat lines and cultivars carrying Sr36, Sr31+Sr36, and Sr24+Sr31. Of the 18 isolates, 10 produced infection types 3+ to 4 on line W2691SrTt-1 (monogenic for Sr36) and other lines that carry Sr36 and belonged to a new virulence phenotype that was not detected in previous years. These isolates were identified as race TTTSK. The remaining eight isolates were identified its races TTKSK (five isolates) and TTKST (three isolates), with avirulence and virulence, respectively, to Sr24. Thirteen simple sequence repeat (SSR) markers were used to examine the genetic relationships among the three races in the TTKS lineage. All isolates in the lineage shared ail identical SSR genotype and were clearly different from North American races. In all, 16 wheat cultivars and 60 elite breeding lines, postulated to possess Sr36, were susceptible to race TTTSK. The occurrence of race TTTSK with combined virulence oil Sr31 and Sr36 has further broadened the virulence spectrum of the TTKS lineage and rendered an important source of resistance ineffective.

TI Disease Risk of Potting Media Infested with Phytophthora ramorum Under Nursery Conditions SO PLANT DISEASE LA English DT Article ID FOREST; SOIL; CALIFORNIA; SUSCEPTIBILITY; DECOMPOSITION; RHODODENDRON; CELLULOSE; SURVIVAL; LIGNIN; ROOTS AB Phytophthora ramorum has been found in potting media of containerized plants; however, the role of intested media oil disease development under nursery conditions is unknown. This study assesses pathogen survival, sporulation, and infectivity to rhododendron plants in nursery pots with infected leaf litter that were maintained under greenhouse and field conditions. The influence of environmental conditions and irrigation method oil disease incidence was also assessed. Infected leaf disks were buried below the Soil Surface of potted rhododendrons and retrieved at approximately 10-week intervals for up to 66 weeks. Pathogen survival was assessed by either isolation or induction of sporulation in water over three experimental periods. P ramorum was recovered from infected leaf disks incubated in planted pots for longer than 1 year. Chlamydospores and sporangia formed on hydrated leaf disks but relative production of each spore type varied with the duration of incubation in soil. Root infections were detected after 40 weeks in infested soil. Foliar infections developed on lower leaves hut only after spring rain events. Sprinkler irrigation promoted the development of foliar infections no disease incidence was observed in drip-irrigated plants unless foliage was in direct contact with infested soil. Management implications are discussed. C1 [Tjosvold, S. A.; Chambers, D. L.] Univ Calif Cooperat Extens, Watsonville, CA USA. [Fichtner, E.

Cultivars resistant to FLS have been developed for planting in the southern United States and resistance in many of these cultivars is conditioned by the Rcs3 gene. This gene conditions immunity to all known races and isolates of the pathogen. Resistance to C. sofijina in soybean genotypes (cultivars and breeding lines) adapted to north-central U.S. production region is unknown. The objectives of this study were to (i) identify maturity group (MG) III, IV, and V soybean genotypes resistant to C sojina race 11 by field screening at multiple locations over years and (ii) determine whether FLS resistance in these genotypes is likely to be conditioned by the Rcs3 gene. In total, 1,350 genotypes were evaluated for resistance to race 11 in field trials, and 13 MG III, 45 MG IV, and 15 MG V genotypes did not develop symptoms of FLS. Of these, 54 were subsequently tested for the possible presence of Rcs3 using five molecular markers located within 2 centimorgans (cM) of the gene. None of the MG III genotypes tested had the Rcs3 haplotype of cv. Davis, the source of Rcs3; six of the MG IV genotypes and seven of the MG V genotypes had the Rcs3 haplotype. This is the first report of the presence of the Rcs3 haplotype in LN 97-15076 and S99-2281. The soybean genotypes predicted to have the Rcs3 gene and other genotypes with no FLS symptoms in field trials may be useful in developing soybean cultivars with broad resistance to FLS and adapted to the northern United States.

TI Comparison of Assessment of Citrus Canker Foliar Symptoms by Experienced and Inexperienced Raters SO PLANT DISEASE LA English DT Article ID DISEASE ASSESSMENT; VISUAL ESTIMATION; BACTERIAL SPOT; WINTER-WHEAT; ACCURACY; PRECISION; RELIABILITY; INTENSITY; SEVERITY; FECHNER AB Citrus canker (Xanthomonas citri subsp. citri) is destructive in many citrus production regions in tropical and subtropical parts of the world. Assessment of canker symptoms is required for diverse reasons, including monitoring epidemics, evaluating the efficacy of control strategies, and disease response in breeding material. The objectives were to compare the ability of experienced and inexperienced raters at assessing citrus canker, to identify factors that affect the quality of the assessment, to determine common sources of error, and to discern how error is related to actual disease magnitude. Two-hundred digital leaf images (0 to 37% area infected) were assessed once by 28 raters, five of whom were experienced plant pathologists (PPs), and 23 who had no experience in disease severity assessment (NPPs). True disease (lesion number [LN], % necrotic area [%N], and % chlorotic+necrotic area [%CN]) was measured using image analysis on a leaf-by-leaf basis, and each parameter was estimated by the 28 raters. LN was neither severely over- nor underestimated, while %N was greatly overestimated, with a lesser tendency to overestimate %CN over the true severity range of these two symptom types. A linear relationship existed between estimate of the disease and true disease for all measures of severity. Data were heteroscedastic and error was not constant with increasing true disease. Agreement between rater estimates and true disease was measured with Lin's concordance correlation coefficient (p,). LN showed greatest agreement (rho(c) = 0.88 to 0.99), followed by %CN (rho(c) = 0.80 to 0.95) and %N (p, = 0.19 to 0.84). Greater lesion number resulted in overestimation of area infected for both %N and %CN. Overestimation was particularly noticeable at low disease severities. There was a linear relationship between log variance and log true disease for LN (r(2) = 0.71), %N (r(2) = 0.85), and %CN (r2 = 0.88), and raters tended to estimate disease above 10% to the nearest 5 or 10% GLM analysis showed differences between PP and NPP groups in assessing disease. For LN precision of assessment for both groups was similar (r(2) > 0.92 and 0.94, respectively), but for estimates of %N and %CN, the PPs were more precise (%N and %CN, r(2) = 0.61 and 0.73, respectively) compared to NPPs (%N and %CN, r(2) = 0.45 and 0.58, respectively). Absolute error for mean LN was low. The absolute error of %N and %CN showed overestimation to approximately 8% area infected. Above 8%, absolute error increased, but comprised both over- and underestimation. For %N and %CN, relative error was almost exclusively positive and dramatic at severity <8% (up to approximately 600%), but at severity >10% it was relatively small. Error in rater estimates of canker severity is ubiquitous. Understanding these sources of error will aid in the development of both appropriate training and relevant rating aids. C1 [Bock, C.

We compared the activities of several enzymes and cellular metabolites involved in the ROS scavenging pathways in two isogenic cell lines of poplar (Populus nigra x maximowiczii) differing in their PA contents. Whereas the control cell line was transformed with beta-glucuronidase (GUS), the other, called HP (High Putrescine), was transformed with a mouse ornithine decarboxylase (mODC) gene. The expression of mODC resulted in several-fold increased production of putrescine as well its enhanced catabolism. The two cell lines followed a similar trend of growth over the seven-day culture cycle, but the HP cells had elevated levels of soluble proteins. Accumulation of H(2)O(2) was higher in the HP cells than the control cells, and so were the activities of glutathione reductase and monodehydroascorbate reductase; the activity of ascorbate peroxidase was lower in the former. The contents of reduced glutathione and glutamate were significantly lower in the HP cells but proline was higher on some days of analysis. There was a small difference in mitochondrial activity between the two cell lines, and the HP cells showed increased membrane damage. In the HP cells, increased accumulation of Ca was concomitant with lower accumulation of K. We conclude that, while increased putrescine accumulation may have a protective role against ROS in plants, enhanced turnover of putrescine actually can make them vulnerable to increased oxidative damage.

The effectors are collectively essential but individually dispensable for the ability of the bacteria to defeat defenses, grow, and produce symptoms in plants. Eighteen of the effector genes are clustered in six genomic islands/islets. Combinatorial deletions involving these clusters and two of the remaining effector genes revealed a redundancy-based structure in the effector repertoire, such that some deletions diminished growth in N. benthamiana only in combination with other deletions. Much of the ability of DC3000 to grow in N. benthamiana was found to be due to five effectors in two redundant-effector groups (REGs), which appear to separately target two high-level processes in plant defense: perception of external pathogen signals (AvrPto and AvrPtoB) and deployment of antimicrobial factors (AvrE, HopM1, HopR1). Further support for the membership of HopR1 in the same REG as AvrE was gained through bioinformatic analysis, revealing the existence of an AvrE/DspA/E/HopR effector superfamily, which has representatives in virtually all groups of proteobacterial plant pathogens that deploy type III effectors.

TI Retnla (Relm alpha/Fizz1) Suppresses Helminth-Induced Th2-Type Immunity SO PLOS PATHOGENS LA English DT Article ID RESISTIN-LIKE-MOLECULE; GENE-EXPRESSION PROFILES; INDUCED LUNG FIBROSIS; NEMATODE PARASITES; ALTERNATIVE ACTIVATION; PULMONARY INFLAMMATION; MACROPHAGE ACTIVATION; ALVEOLAR MACROPHAGES; LIVER FIBROSIS; INFECTION AB Retnla (Resistin-like molecule alpha/FIZZ1) is induced during Th2 cytokine immune responses. However, the role of Retnla in Th2-type immunity is unknown. Here, using Retnla(-/-) mice and three distinct helminth models, we show that Retnla functions as a negative regulator of Th2 responses. Pulmonary granuloma formation induced by the eggs of the helminth parasite Schistosoma mansoni is dependent on IL-4 and IL-13 and associated with marked increases in Retnla expression. We found that both primary and secondary pulmonary granuloma formation were exacerbated in the absence of Retlna. The number of granuloma-associated eosinophils and serum IgE titers were also enhanced. Moreover, when chronically infected with S. mansoni cercariae, Retnla(-/-) mice displayed significant increases in granulomatous inflammation in the liver and the development of fibrosis and progression to hepatosplenic disease was markedly augmented. Finally, Retnla(-/-) mice infected with the gastrointestinal (GI) parasite Nippostrongylus brasiliensis had intensified lung pathology to migrating larvae, reduced fecundity, and accelerated expulsion of adult worms from the intestine, suggesting Th2 immunity was enhanced. When their immune responses were compared, helminth infected Retnla(-/-) mice developed stronger Th2 responses, which could be reversed by exogenous rRelm alpha treatment. Studies with several cytokine knockout mice showed that expression of Retnla was dependent on IL-4 and IL-13 and inhibited by IFN-gamma, while tissue localization and cell isolation experiments indicated that eosinophils and epithelial cells were the primary producers of Retnla in the liver and lung, respectively. Thus, the Th2-inducible gene Retnla suppresses resistance to GI nematode infection, pulmonary granulomatous inflammation, and fibrosis by negatively regulating Th2-dependent responses.

Severity of internal browning and flesh mealiness, firmness, extractable juice, total soluble solids (TSS), total acid, vitamin C and total phenolic contents were measured after 3 and 5 weeks of storage at 0 degrees C plus 3 d at 20 degrees C for shelf-life. The activities of phenylalanine ammonia-lyase (PAL, EC 4.3.1.5), superoxide dismutase (SOD, EC 1.15.1.1), polyphenol oxidase (PPO, EC 1.10.3.1), peroxidase (POD, EC 1.11.1.7), pectin-methylesterase (PME, EC 3.1.1.11) and polygalacturonase (PG, EC 3.2.1.15) were analyzed during the cold storage period. The results showed that fruit treated with 1 mu mol L-1 MJ vapor at 38 degrees C for 12 h (HMJ), and heat treatment at 38 degrees C for 12 h and then treated with 1 mu mol L-1 MJ vapor at 20 degrees C for 24 h (HA + MJ) had the highest quality and lowest percent of chilling injury symptoms. HA treatment alone significantly inhibited internal browning, but caused more severe flesh mealiness than other treatments. This side effect was counteracted by MJ. The percent of extractable juice in combined treatments was higher than that in the control, however, no significant effect was found on firmness. TSS was 23% and 25.3% higher and total acid was 59.4% and 62.5% higher in treatments of HMJ and HA + MJ, respectively, than those in control fruit after storage for 5 weeks. Vitamin C and total phenolic contents were also maintained at higher levels in combined treatments. In addition, the combined treatments resulted in higher activities of PAL, SOD and PG, and lower activities of PPO, and POD than the control. The combination or HA and MJ vapor treatment might be a useful technique to alleviate chilling injury and maintain peach fruit quality during cold storage. (C) 2008 Elsevier B.V. All rights reserved.

Therefore, understanding the dissemination and maintenance of AIV in wild birds is important for understanding the factors that contribute to transmission of AIV from wild birds to poultry. However, relatively little is known about the ecology of the virus in wild birds, and the depth of data are inconsistent worldwide. Also, the biology of the virus itself is very important, because AIV is highly adaptable to different hosts and likely to the environment as well. Some insight may be gained from the Asian H5N1 highly pathogenic AIV lineage, because surveillance for this virus has increased considerably in wild birds worldwide since 2005. Also, numerous species that have not previously been represented in AIV testing have been included in surveillance for the Asian H5N1 highly pathogenic AIV, allowing for a more complete C1 ARS, SE Poultry Res Lab, USDA, Athens, GA 30605 USA.

Although still largely confined to birds, more than 300 human cases resulting in deaths have been reported to the World Health Organization. These sporadic human cases result from direct transmission from infected birds; however, a sustained outbreak of HPAI H5N1 increases the potential for the emergence of a human pandemic strain. One approach to the containment of HPAI H5N1 is the development of vaccines for use in poultry. Currently, the majority of avian influenza vaccines for poultry are traditional whole-virus vaccines produced in eggs. Although highly efficacious, these vaccines are hindered by long production times, inflexibility in quickly altering antigenic composition, and limited breadth of protection. Newer vaccines with more efficient manufacturing processes, enhanced efficacy, and cross-protection against multiple strains would improve preparedness. Reverse genetics technology has provided one such method, and emerging gene-based vaccines offer another approach that reduces dependence on egg-based production and human exposure to pathogenic viruses. Gene-based vaccines also provide rapid manufacturing, enhanced precision and versatility, and the capacity to protect against a broad range of viral subtypes. Vectors for these vaccines include replication-defective viruses, bacterial vectors, and DNA. Here we review the features of gene-based vaccination that may facilitate the control of HPAI H5N1 in poultry, and highlight the development of a hemagglutinin-based multivalent DNA vaccine that confers protection in mice and chickens.

TI Bayesian analysis of within-field variability of corn yield using a spatial hierarchical model SO PRECISION AGRICULTURE LA English DT Article DE Crop yield spatial variability; Bayesian statistics; Conditional auto-regressive model; WinBUGS ID SOIL ELECTRICAL-CONDUCTIVITY; CROP YIELD; TOPOGRAPHY; MISSOURI; USA AB Understanding relationships of soil and field topography to crop yield within a field is critical in site-specific management systems. Challenges for efficiently assessing these relationships include spatially correlated yield data and interrelated soil and topographic properties. The objective of this analysis was to apply a spatial Bayesian hierarchical model to examine the effects of soil, topographic and climate variables on corn yield. The model included a mean structure of spatial and temporal co-variates and an explicit random spatial effect. The spatial co-variates included elevation, slope and apparent soil electrical conductivity, temporal co-variates included mean maximum daily temperature, mean daily temperature range and cumulative precipitation in July and August. A conditional auto-regressive (CAR) model was used to model the spatial association in yield. Mapped corn yield data from 1997, 1999, 2001 and 2003 for a 36-ha Missouri claypan soil field were used in the analysis. The model building and computation were performed using a free Bayesian modeling software package, WinBUGS. The relationships of co-variates to corn yield generally agreed with the literature. The CAR model successfully captured the spatial association in yield. Model standard deviation decreased about 50% with spatial effect accounted for. Further, the approach was able to assess the effects of temporal climate co-variates on corn yield with a small number of site-years. The spatial Bayesian model appeared to be a useful tool to gain insights into yield spatial and temporal variability related to soil, topography and growing season weather conditions.

Collection localities ranged in elevation from 500 to 1,880 m. These locations were forested, or partially forested with some pasture land and coffee plantings, Coffea arabica L. Two active colonies of this wasp were collected and analyzed in May of 2006. The two colonies were subterranean, and the nests had 9 and 11 layers, respectively, of paper comb completely surrounded with external paper envelope. The two nests included 10,581 and 20,715 cells, with 2,818 and 6,105 workers, 203 and 313 queens, and 790 and 454 males respectively. Samples of queens from each nest were dissected. These included numerous queens that were mated and possessed mature eggs, as well as numbers of queens that were unmated and had no eggs. Workers from cacti nest showed no ovarian development. The nest sizes and populations of wasps for these colonies were within ranges of those reported for nests of this species in North America.

There is a wide variety of trichothecene mycotoxins and they all contain a 12,13-epoxytrichothecene skeleton but differ in their substitutions. Indeed, there is considerable variation in the toxin profile across the numerous Fusarium species that has been ascribed to differences in the presence or absence of biosynthetic enzymes and their relative activity. This article addresses the source of differences in acetylation at the C15 position of the trichothecene molecule. Here, we present the in vitro structural and biochemical characterization of TRI3, a 15-O-trichothecene acetyltransferase isolated from F. sporotrichioides and the "in vivo'' characterization of Delta tri3 mutants of deoxynivalenol (DON) producing F. graminearum strains. A kinetic analysis shows that TRI3 is an efficient enzyme with the native substrate, 15-decalonectrin, but is inactive with either DON or nivalenol. The structure of TRI3 complexed with 15-decalonectrin provides an explanation for this specificity and shows that Tri3 and Tri101 (3-O-trichothecene acetyltransferase) are evolutionarily related. The active site residues are conserved across all sequences for TRI3 orthologs, suggesting that differences in acetylation at C15 are not due to differences in Tri3. The tri3 deletion mutant shows that acetylation at C15 is required for DON biosynthesis even though DON lacks a C15 acetyl group. The enzyme(s) responsible for deacetylation at the 15 position of the trichothecene mycotoxins have not been identified.

The reaction products and their corresponding acetylated analogs produce characteristic molecular adduct ions by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS). Analysis of the peracetylated C-glycosides by electron ionization (EI) gas chromatography/mass spectrometry (GC/MS) revealed diagnostic fragment ions that have been used to deduce the El fragmentation pathways and the structure of each C-glycoside ketone. Characteristic gluco- and ribo-specific ions were observed at m/z 350 and 278, respectively. Ions common to both carbohydrate fragmentation pathways were observed at m/z 193 and 169 for the dimedone-C-glycosides, and m/z 165 and 141 for the 1,3-CHD-C-glycosides. Ions with m/z 169 and 141 retain the anomeric carbon (carbon-1) of the original sugar, while m/z 193 and 165 are shown to retain carbons-1, 2, and 3. Published in 2009 by John Wiley & Sons, Ltd.

Typically, LPAIV cause asymptomatic infections in wild aquatic birds, but when introduced into domesticated poultry, infections may be asymptomatic or produce clinical signs and lesions reflecting pathophysiological damage to the respiratory, digestive and reproductive systems. The HPAIV have primarily been seen in gallinaceous poultry, producing high morbidity and mortality, and systemic disease with necrosis and inflammation in multiple visceral organs, nervous and cardiovascular systems, and the integument. Although HPAIV have rarely infected domestic waterfowl or wild birds, the Eurasian-African H5N1 HPAIV have evolved over the past decade with the unique capacity to infect and cause disease in domestic ducks and wild birds, producing a range of syndromes including asymptomatic respiratory and digestive tract infections; systemic disease limited to two or three critical organs, usually the brain, heart and pancreas; and severe disseminated infection and death as seen in gallinaceous poultry. Although experimental studies using intranasal inoculation have produced infection in a variety of wild bird species, the inefficiency of contact transmission in some of them, for example, passerines and Columbiformes, suggests they are unlikely to be a reservoir for the viruses, while others such as some wild Anseriformes, can be severely affected and could serve as a dissemination host over intermediate distances.

TI STATUS OF THE EASTERN GRASSWORT, LILAEOPSIS CHINENSIS (APIACEAE), IN THE GREAT BAY ESTUARY, NEW HAMPSHIRE, USA SO RHODORA LA English DT Article DE conservation status; mesohaline; oligohaline; brackish tidal riverbank marsh; element occurrence; threatened plant AB A survey of oligohaline and mesohaline tidal marshes along the upper reaches of eight tidal rivers in the Great Bay Estuary of New Hampshire was conducted to document the occurrence of eastern grasswort, Lilaeopsis chinensis, a state-listed, rare species. Historical sites were visited to assess the presence, absence, or significant population changes or this rare coastal species. We re-located four of five historically documented element occurrences, noted the plant's potential expansion on several rivers and a decline at three other sites, and identified a new occurrence on a river system with no prior documented accounts. The results suggest that overall, L. chinensis has been relatively stable for the last 60 years, although the loss of plants at three of the sites suggests it is threatened by continued development (dams and tidal restrictions) and associated impacts to water quality.

To gain a better understanding of these influences, we used bioluminescence- and oxygen consumption-based methods to compare bacterial metabolic activity expressed during colonization of two different seed types. Metabolic activity expressed by Enterobacter cloacae during colonization of pea seeds, which exude high levels of reduced carbon nutrients, was compared with that during colonization of cucumber seeds, which exude orders of magnitude less reduced carbon nutrients. Metabolic activity levels expressed by E cloacae populations were much higher throughout a 72 h colonization period on pea seed compared with those observed on cucumber seed, directly correlating metabolic activity level with amounts of nutrients released by seeds. In vitro studies indicated E cloacae cells expressed different levels of metabolic activity when incubated with different individual carbohydrates commonly found in cucumber and pea seed exudates. The addition of exogenous carbohydrate to cucumber seed increased metabolic activity expressed by colonizing E. cloacae; with the level of increase dependent on both quantity and type of carbohydrate supplement. Subtraction of carbohydrate available to E cloacae on cucumber and pea seeds through mutation in pfkA decreased metabolic activity by this bacterium. Results presented here provide strong evidence that metabolic activity of spermosphere-colonizing bacteria is host dependent, and that levels of activity are based largely on both quantitative and qualitative composition of host exudate released during seed germination.

TI Soil Phosphorus Dynamics in Response to Poultry Manure Amendment SO SOIL SCIENCE LA English DT Article DE Aerobic incubation; enzyme hydrolysis; phosphorus; poultry manure; sequential fractionation ID NUCLEAR-MAGNETIC-RESONANCE; LONG-TERM; ORGANIC-PHOSPHATES; SEQUENTIAL EXTRACTS; ANIMAL MANURE; FRACTIONATION; TRANSFORMATIONS; MINERALIZATION; ORTHOPHOSPHATE; HYDROLYSIS AB Manure amendments are an excellent source of phosphorus (11) for crop production; however, animal manures differ in P availability. Poultry manure (PM) contains more stable mineral-associated P than many manures and may act as a longer-term P source when used in crop production. We used sequential fractionation and enzyme hydrolysis to evaluate the short-term effects of incorporating 0, 100, and 200 mg PM P kg(-1) of soil into two Maine soils. Results indicated that most PM P was present in the H(2)O- and HCl-soluble fractions (1936 and 5956 mg P kg(-1) manure, respectively), and that a large portion of stable organic P was present in the HCl fraction (3288 mg kg(-1)). Poultry manure application resulted in only a transient increase in H(2)O-P(i), implying rapid transfer to other fractions. A transformation of P(i) from the NaHCO(3) to the NaOH fraction was observed at Day 84 of the incubation with all treatments, indicating that soil properties influenced PM P dynamics. In the HCl fraction, some organic P became hydrolyzable and a portion was converted to other fractions. Comparing these data with those of a complementary study indicated that P from PM interacted differently with soil than did P from dairy manure. The observation of active interchange of P in different fractions during the incubation indicated that soil amendment with moderate levels of PM does not lead to accumulation of stable P forms and that the large HCl-P fraction (31.1% Of total P) unique to PM could act as a source of plant-available P in a short term (e.g., a growing season).

Scarcity of data on greenhouse gas emissions as influenced by landscape variability and agroecosystem management in southeastern United States necessitates study. The objective of this study was to evaluate effects of landscape variability and agroecosystem management on methane (CH(4)), nitrous oxide (N(2)O), and carbon dioxide (CO(2)) emissions on. a Coastal Plain catena (Typic, Oxyaquic, and Aquic Paleudults) in Alabama. Soil management strategies included (i) conventional tillage (CT), (ii) conservation tillage (CsT), (iii) CT with dairy manure (CTM), and 4) CsT with dairy manure (CsTM) on a corn (Zea mays L.)-cotton (Gossypium hirsutum L.) rotation. Each soil management treatment was replicated on summit, sideslope, and the drainageway landscape position. Gas measurements were conducted using a closed chamber method. The drainageway emitted 46, 251, 59, and 185 mg CH(4)-C ha(-1) h(-1) from CT, CTM, CsT, and CsTM treatments, respectively The summit position had fluxes of -59 and -90 mg CH(4)-C ha(-1) h(-1) on CT and CsT treatments, respectively. Averaged across seasons, CT and CsT N(2)O fluxes were similar (547 and 437 mg N(2)O-N ha(-1) h(-1), respectively) in the drainageway landscape position. Winter 2005 CO(2) emission from CsT treatments (averaged across landscape positions) was 1304 g CO-C compared with 227 g ha(-1) h(-1) CO(2)-C from CT treatments.

TI Inter- and intra-genomic heterogeneity of the intervening sequence in the 23S ribosomal RNA gene of Compylobacter jejuni and Campylobacter coli SO SYSTEMATIC AND APPLIED MICROBIOLOGY LA English DT Article DE 23S rRNA gene; Diversity; Concerted evolution; Campylobacter; Horizontal gene transfer; Polymorphisms ID MOLECULAR CHARACTERIZATION; TRANSCRIBED SPACERS; BACTERIAL EVOLUTION; TYPING SYSTEM; STRAINS; IDENTIFICATION; PCR; 16S; RECOMBINATION; COALESCENT AB An intervening sequence (IVS) can be present or absent in the 23S rRNA of Campylobacter jejuni and Campylobacter coli. As part of a survey, we used a polymerase chain reaction (PCR) assay to detect the presence of the IVS in 43 isolates of C coli and 82 isolates of C jejuni. An IVS was present in 40 (93.0%) of the C coli and only 34 (41.5%) of the C jejuni isolates. Twelve (27.9%) of the C coli isolates and seven (8.5%) of the C jejuni isolates resulted in two polymerase chain reaction products, indicating heterogeneity in the presence of the 23S rRNA IVS. Fourteen of the isolates with two products were evaluated by pulse-field gel electrophoresis; 13 different patterns were observed. The total band size of one isolate was substantially greater than the expected 1.7 Mb, possibly indicating a mixed culture. Southern blot analyses demonstrated the expected three rRNA operons in all tested isolates. Nested PCR reactions with operon-specific primers followed by primers for the IVS confirmed that the strains of interest contained either one or two operons carrying the IVS and the remaining operon(s) did not. Sequence analysis of the IVS and flanking regions of the 23S rRNA genes did not discriminate C jejuni and C coli as distinct populations. These results indicate horizontal transfer of 23S rRNA genes or portions of the genes between C jejuni and C coli. Also, data showing sequence polymorphisms between the three 23S rRNA loci outside of the IVS region suggest that the isolates with intra-genomic heterogeneity appear to be members of clones that have an ancient defect in gene conversion mechanisms needed for concerted evolution of the ribosomal operons.

TI The Ascomycota Tree of Life: A Phylum-wide Phylogeny Clarifies the Origin and Evolution of Fundamental Reproductive and Ecological Traits SO SYSTEMATIC BIOLOGY LA English DT Article DE Ancestral character reconstruction; Fungi; large data sets; lichenization; phylogeny ID RNA-POLYMERASE-II; MULTIPLE SEQUENCE ALIGNMENT; FUNGAL LINEAGES; CLEISTOTHECIAL FUNGI; CLASSIFICATION; SUBUNIT; PEZIZOMYCOTINA; DIVERGENCE; MORPHOLOGY; EUKARYOTES AB We present a 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi. This analysis is the most taxonomically complete to date with species sampled from all 15 currently circumscribed classes. A number of superclass-level nodes that have previously evaded resolution and were unnamed in classifications of the Fungi are resolved for the first time. Based on the 6-gene phylogeny we conducted a phylogenetic informativeness analysis of all 6 genes and a series of ancestral character state reconstructions that focused on morphology of sporocarps, ascus dehiscence, and evolution of nutritional modes and ecologies. A gene-by-gene assessment of phylogenetic informativeness yielded higher levels of informativeness for protein genes (RPB1, RPB2, and TEF1) as compared with the ribosomal genes, which have been the standard bearer in fungal systematics. Our reconstruction of sporocarp characters is consistent with 2 origins for multicellular sexual reproductive structures in Ascomycota, once in the common ancestor of Pezizomycotina and once in the common ancestor of Neolectomycetes. This first report of dual origins of ascomycete sporocarps highlights the complicated nature of assessing homology of morphological traits across Fungi. Furthermore, ancestral reconstruction supports an open sporocarp with an exposed hymenium (apothecium) as the primitive morphology for Pezizomycotina with multiple derivations of the partially (perithecia) or completely enclosed (cleistothecia) sporocarps. Ascus dehiscence is most informative at the class level within Pezizomycotina with most superclass nodes reconstructed equivocally. Character-state reconstructions support a terrestrial, saprobic ecology as ancestral. In contrast to previous studies, these analyses support multiple origins of lichenization events with the loss of lichenization as less frequent and limited to terminal, closely related species.

Using 3076 bp of DNA sequence from three genes [cytochrome oxidase I (COI), CAD (rudimentary), phosphogluconate dehydrogenase (PGD)] and 113 exemplar species, we identified and tested the monophyly of host-associated species groups in Phytomyza and Chromatomyia and investigated the phylogenetic relationships among these groups. Chromatomyia is polyphyletic and nested largely within Phytomyza; two small groups of species, however, are related more closely to Ptochomyza and Napomyza. Therefore, we synonymize Chromatomyia syn.n., Ptochomyza syn.n., and Napomyza syn.n. with Phytomyza, recognizing Ptochomyza, Napomyza and Phytomyza sensu stricto as subgenera of Phytomyza. We recognize five major clades within Phytomyza sensu stricto that comprise the majority of species ascribed previously to Chromatomyia and Phytomyza. Many species groups recognized previously were recovered as monophyletic, or virtually so, but some (e.g. robustella and atomaria groups) required emendation. On the basis of the proposed phylogeny and recent taxonomic literature, we present a preliminary revision of 24 species groups within Phytomyza, but leave many species unplaced. Evolution of internal pupariation (within the host's tissue), regarded as a defining character of the former Chromatomyia, is discussed with regard to the new phylogeny, and we suggest a correlation with stem or leaf midrib mining. The large size of the Phytomyza lineage and an inferred pattern of host family-specific species radiations make it a promising candidate for the study of macroevolutionary patterns of host shift and diversification in phytophagous insects. The proposed generic synonymies necessitate a number of new combinations. The following 46 species described in Chromatomyia are transferred to Phytomyza: P. actinidiae (Sasakawa) comb.n., P. alopecuri (Griffiths) comb.n., P. arctagrostidis (Griffiths) comb.n., P. beigerae (Griffiths) comb.n., P. blackstoniae (Spencer) comb.n., P. centaurii (Spencer) comb.n., P. chamaemetabola (Griffiths) comb.n., P. cinnae (Griffiths) comb.n., P. compta (Spencer) comb.n., P. cygnicollina (Griffiths) comb.n., P. doolittlei (Spencer) comb.n., P. elgonensis (Spencer) comb.n., P. eriodictyi (Spencer) comb.n., P. flavida (Spencer) comb.n., P. fricki (Griffiths) comb.n., P. furcata (Griffiths) comb.n., P. griffithsiana (Beiger) comb.n., P. hoppiella (Spencer) comb.n., P. ixeridopsis (Griffiths) comb.n., P. kluanensis (Griffiths) comb.n., P. leptargyreae (Griffiths) comb.n., P. linnaeae (Griffiths) comb.n., P. luzulivora (Spencer) comb.n., P. mimuli (Spencer) comb.n., P. mitchelli (Spencer) comb.n., P. montella (Spencer) comb.n., P. nigrilineata (Griffiths) comb.n., P. nigrissima (Spencer) comb.n., P. orbitella (Spencer) comb.n., P. paraciliata (Godfray) comb.n., P. poae (Griffiths) comb.n., P. pseudomilii (Griffiths) comb.n., P. qinghaiensis (Gu) comb.n., P. rhaetica (Griffiths) comb.n., P. scabiosella (Beiger) comb.n., P. seneciophila (Spencer) comb.n., P. shepherdiana (Griffiths) comb.n., P. spenceriana (Griffiths) comb.n., P. styriaca (Griffiths) comb.n., P. subnigra (Spencer) comb.n., P. suikazurae (Sasakawa) comb.n., P. symphoricarpi (Griffiths) comb.n., P. syngenesiae (Hardy) comb.n., P. thermarum (Griffiths) comb.n., P. torrentium (Griffiths) comb.n. and P. tschirnhausi (Griffiths) comb.n. Furthermore, we transfer all species of Napomyza to Phytomyza, resulting in the following new combinations: P. achilleanella (Tschirnhaus) comb.n., P. acutiventris (Zlobin) comb.n., P. angulata (Zlobin) comb.n., P. arcticola (Spencer) comb.n., P. bellidis (Griffiths) comb.n., P. carotae (Spencer) comb.n., P. cichorii (Spencer) comb.n., P. curvipes (Zlobin) comb.n., P. dubia (Zlobin) comb.n., P. filipenduliphila (Zlobin) comb.n., P. flavivertex (Zlobin) comb.n., P. flavohumeralis (Zlobin) comb.n., P. genualis (Zlobin) comb.n., P. grandella (Spencer) comb.n., P. humeralis (Zlobin) comb.n., P. immanis (Spencer) comb.n., P. immerita (Spencer) comb.n., P. inquilina (Kock) comb.n., P. kandybinae (Zlobin) comb.n., P. lacustris (Zlobin) comb.n., P. laterella (Zlobin) comb.n., P. manni (Spencer) comb.n., P. maritima (Tschirnhaus) comb.n., P. merita (Zlobin) comb.n., P. mimula (Spencer) comb.n., P. minuta (Spencer) comb.n., P. montanoides (Spencer) comb.n., P. neglecta (Zlobin) comb.n., P. nigriceps (van der Wulp) comb.n., P. nugax (Spencer) comb.n., P. pallens (Spencer) comb.n., P. paratripolii (Chen & Wang) comb.n., P. plumea (Spencer) comb.n., P. plumigera (Zlobin) comb.n., P. prima (Zlobin) comb.n., P. pubescens (Zlobin) comb.n., P. schusteri (Spencer) comb.n., P. scrophulariae (Spencer) comb.n., P. suda (Spencer) comb.n., P. tanaitica (Zlobin) comb.n., P. tenuifrons (Zlobin) comb.n., P. vivida (Spencer) comb.n., P. xizangensis (Chen & Wang) comb.n. and P. zimini (Zlobin) comb.n.

TI QTL, additive and epistatic effects for SCN resistance in PI 437654 SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID SOYBEAN CYST-NEMATODE; MARKER-ASSISTED SELECTION; QUANTITATIVE TRAIT LOCI; NEAR-ISOGENIC LINES; HETERODERA-GLYCINES; PLANT INTRODUCTIONS; GENETIC-RELATIONSHIPS; MOLECULAR MARKERS; COMPLEX TRAITS; RFLP MARKERS AB PI 437654 is a unique accession because of its resistance to nearly all HG types (races) of soybean cyst nematode (Heterodera glycines Ichinohe; SCN). Objectives of this study were to confirm and refine the locations and gene action associated with SCN resistance previously discovered in PI 437654, and to identify new QTLs that may have been missed because of low coverage with genetic markers used in previous studies. Using 205 F(7:9) RILs and 276 SSR and AFLP molecular markers covering 2,406.5 cM of 20 linkage groups (LGs), we confirmed and refined the locations of major SCN resistance QTLs on LG-A2, -B1, and -G previously identified in PI 437654 or other resistant sources. We found that these major QTLs have epistatic effects among them or with other loci for SCN resistance. We also detected some new QTLs with additive or epistatic effects for SCN resistance to different HG types (races) on all LGs except LGs-B2 and -D1b. The QTL on LG-G was associated with resistance to HG types 2.5.7, 1.2.5.7, 0, and 2.7 (races 1, 2, 3, and 5), and it contributed a large proportion of the additive effects. The QTL on LG-A2 was associated with resistance to HG types 2.5.7 and 0 (races 1 and 3). The QTL on LG-B1, associated with resistance to HG types 2.5.7, 0, 2.7 (races 1, 3, and 5), was the similar QTL found in PI 90763 and PI 404198B. In addition to QTL on LGs-A2, -B1 and -G, a novel additive QTL associated with SCN resistance to HG types 0, 2.7, and 1.3.5.6.7 (race 3, 5, and 14) was identified on LG-I flanked by Sat_299 and Sat_189. Several minor QTLs on LGs-C1, D1a, H, and K were also found to be associated with SCN resistance. Confirmation of the new resistance QTL is underway by evaluating another RIL population with a different genetic background.

Previously, we reported that ParA is active in the fission yeast Schizosaccharomyces pombe. In this work, the parA recombinase gene was placed under the control of the Arabidopsis OXS3 promoter and introduced into Arabidopsis lines harboring a chromosomally integrated MRS-flanked target. The ParA recombinase excised the MRS-flanked DNA and the excision event was detected in subsequent generations in the absence of ParA, indicating germinal transmission of the excision event. The precise site-specific deletion by the ParA recombination system in planta demonstrates that the ParA recombinase can be used to remove transgenic DNA, such as selectable markers or other introduced transgenes that are no longer desired in the final product.

TI Water Vapor Diffusion Through Soil as Affected by Temperature and Aggregate Size SO TRANSPORT IN POROUS MEDIA LA English DT Article DE Diffusion coefficient; Absorption; Thermal gradient; Fick's law ID GAS-DIFFUSION; GASEOUS-DIFFUSION; UNDISTURBED SOIL; POROUS-MEDIA; COEFFICIENT; TRANSPORT; MODEL AB Water vapor diffusion through the soil is an important part in the total water flux in the unsaturated zone of arid or semiarid regions and has several significant agricultural and engineering applications because soil moisture contents near the surface are relatively low. Water vapor diffusing through dry soil is absorbed for both long and short terms. Long-term absorption allows more water to enter than exit the soil, as reflected in the concentration gradient. Short-term absorption leads to an apparent reduction in the diffusion rate, as reflected in the diffusion coefficient. This investigation studied the effects of soil temperature and porosity on the isothermal diffusion of water vapor through soil. The diffusion model consisted of 25.4 cm x 8.9 cm x 20.3 cm Plexiglas box divided into two compartments by a partition holding a soil reservoir. Water vapor moved from a container suspended by a spring in one compartment, through the porous medium in the center of the model, to calcium chloride in a container suspended by a spring in the other compartment. The porous materials consisted of aggregates of varying size (2-2.8, 1-2, and 0.5-1 mm) of a Fayatte silty clay loam (a fine-silty, mixed mesic Typic Hapludalf). The flow rates of water vapor were measured at temperatures of 10, 20, 30, and 40A degrees C. Warmer temperatures increased the rate of diffusion through dry soil while reduced the amount of water absorbed by that soil. Reducing porosity slowed the rate of diffusion and increased the amount of water absorbed. The dry soil in this study absorbed from 1/8 to 2/3 of the diffusing water. Maximum absorption rates occurred with the most compact soil samples at the highest temperature, though the maximum absorption as a percentage of the diffusing water was in the compact samples at the lowest temperature. The diffusivity equation D/D (0) = [(S - 0.1)/0.9](2) fit the D/D (0) values obtained from these data if a coefficient of 1/3 or 1/3.5 is added to correct for the time delays caused by temporary sorption of the diffusing water vapor. The data, influenced by the interaction of water vapor and soil materials, represent a diffusion rate lower than the diffusion rate that would have resulted without this interaction.

MILL.; SSR MARKERS; MICROSATELLITE MARKERS; GERMPLASM COLLECTION; POLYMORPHISM; BORKH.; RESISTANCE; CULTIVARS; TRAITS; NUMBER AB Malus sieversii (Lebed.) M. Roem. is a wild progenitor species of the domesticated apple. It is found across a mountainous region of central Asia and has been the focus of several collection expeditions by the USDA-ARS-National Plant Germplasm System. This study used microsatellite variation at seven loci to estimate diversity and differentiation within M. sieversii using several complimentary approaches. Multilocus genotypes were amplified from 949 individuals representing seedling trees from 88 half-sib families from eight M. sieversii populations collected in Kazakhstan. Apportioning of genetic variation was estimated at both the family and site level. Analyses using a hierarchical model to estimate F (st) showed that differentiation among individual families is more than three times greater than differentiation among sites. In addition, average gene diversity and allelic richness varied significantly among sites. A rendering of a genetic network among all sites showed that differentiation is largely congruent with geographical location. In addition, nonhierarchical Bayesian assignment methods were used to infer genetic clusters across the collection area. We detected four genetic clusters in the data set. The quality of these assignments was evaluated over multiple Markov Chain Monte Carlo runs using both posterior likelihood and stability of the assignments. The spatial pattern of genetic assignments among the eight collection sites shows two broadly distributed and two narrowly distributed clusters. These data indicate that the southwestern collection sites are more admixed and more diverse than the northern sites.

TI Effect of bromelain on milk yield, milk composition and mammary health in dairy goats SO TROPICAL ANIMAL HEALTH AND PRODUCTION LA English DT Article DE Bromelain; Goat; Milk composition; Milk production; Subclinical intrammamary infection ID CLINICAL-APPLICATION; ESCHERICHIA-COLI; IN-VITRO; ENZYME AB A 7 month prospective cohort study was designed to determine if feeding bromelain to dairy goats influenced the MSCC, milk yield, milk composition and the incidence of IMI. Forty-four clinically normal goats from 2nd to 6th parities were studied. Daily bromelain dosage was 7.4 grams/animal (185-mg/Kg weight). Samples for diagnostic bacteriology were collected from each udder half every 2 weeks. Samples for MSCC and composition were obtained every 42 days. Milk yield was also recorded every 42 days. Bromelain affected milk protein and fat but not MSCC, milk yield or milk lactose. Bromelain did not decrease the MSCC in healthy goats. Milk protein and fat increased in the bromelain treated group (P < 0.01), which is important for dairymen because premiums are paid milk fat and protein content. No clinical mastitis was detected in the goats for the total study period and incidence rate of subclinical IMI was 5.7%. Relative risk was 1.50 (0.28 < RR < 8.12) which means that the bromelain had no significant effect on IMI (P > 0.05). In addition, the use of pineapple by-products could be especially important in tropical countries were pineapple waste seems to be a pollution problem. C1 [Contreras, A.; Corrales, J.

TI Establishing the Geographical Distribution and Level of Acetolactate Synthase Resistance of Palmer Amaranth (Amaranthus palmeri) Accessions in Georgia SO WEED TECHNOLOGY LA English DT Article DE Herbicide resistance; acetolactate synthase; dose-response; weed resistance ID COTTON GOSSYPIUM-HIRSUTUM; CONFER HERBICIDE RESISTANCE; ALS-INHIBITING HERBICIDES; POWELL AMARANTH; REDROOT PIGWEED; SULFONYLUREA HERBICIDES; HYBRIDUS POPULATIONS; INTERFERENCE; RUDIS; WEEDS AB Palmer amaranth resistance to acetolactate synthase (ALS)-inhibiting herbicides was first identified in Georgia in 2000. Since then, complaints from peanut producers have increased concerning failure of ALS herbicides in controlling Palmer amaranth. Because efficacy of ALS herbicides can be compromised under adverse conditions, seeds from Palmer amaranth plants that escaped weed control were collected across the peanut-growing region in Georgia to investigate the cause of these reported failures. Greenhouse and growth-chamber studies were conducted using these seeds to evaluate whether weed escapes were a result of Palmer amaranth resistance to ALS herbicides. Each of the 61 accessions collected across Georgia exhibited varying levels of resistance to imazapic applied POST (< 55% control, relative to ALS-Susceptible Palmer amaranth). Subsamples of the accessions were evaluated for their response to imazapic rates, which indicated variable levels of resistance across Palmer amaranth accessions. The rate of imazapic that provided 50% reduction in Palmer amaranth plant biomass (150) for the known susceptible biotype was 0.9 g/ha of imazapic. Of the 10 accessions evaluated, 8 of them had 150 values that ranged from 3 to 297 g/ha of imazapic. The other two accessions could not be fit to the log-logistic dose-response curve and had undeterminable 150 values because of high levels of ALS resistance (> 1,400 g/ha of imazapic). Herbicide cross-resistance experiments indicated char 30 accessions were resistant to the ALS herbicides imazapic, chlorimuron, pyrithiobac, and diclosulam at the recommended field-use rates. However, each of these 30 accessions was Susceptible to glyphosate. These data demonstrate that ALS-resistant Palmer amaranth occurs throughout the peanut-growing region of Georgia. Growers in Georgia will need to alter their weed-control programs in peanut to include herbicides with multiple modes of action that do nor rely oil ALS herbicides for effective Palmer amaranth control.

Herbicide applications included diclosulam and flumioxazin applied PRE alone or followed by imazapic applied early postemergence (EPOST). All possible combinations of diclosulam at 0, 13.5, or 27 g ai/ha and flumioxazin at 0, 53, or 105 g ai/ha applied PRE were included. Imazapic was applied at 35 g ai/ha. Ivyleaf morningglory was controlled more than 87% when imazapic was applied EPOST regardless of PRE herbicide. Pitted morningglory control > 67% was observed with applications of diclosulam (27 g/ha) followed by imazapic, diclosulam (13.5 g/ha) plus flumioxazin (53 g/ha), diclosulam (13.5 g/ha) Plus flumioxazin (105 g/ha), and diclosulam (27 g/ha) plus flumioxazin (105 g/ha). Sicklepod was controlled more than 74% with flumioxazin (53 g/ha) followed by imazapic and diclosulam (27 g/ha) Plus flumioxazin (105 g/ha) followed by imazapic. Florida beggarweed was controlled more than 84% by all PRE herbicide combinations except flumioxazin (53 g/ha) alone or diclosulam (27 g/ha) alone or with imazapic. Yellow nutsedge was controlled at least 90% with diclosulam at either rate followed by imazapic and by diclosulam plus flumioxazin followed by imazapic regardless of rate. Pod yield was generally higher when herbicides were applied regardless of herbicide combination or rate.

TI Equations to Convert Compacted Crown Ratio to Uncompacted Crown Ratio for Trees in the Interior West SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE canopy fuel; crown modeling; FIA; forest inventory and analysis; nonlinear regression ID PREDICTION MODELS; UNITED-STATES; VALIDATION; STANDS AB Crown ratio is the proportion of total tree length supporting live foliage. Inventory programs of the US Forest Service generally define crown ratio in terms of compacted or uncompacted measurements. Measurement of compacted crown ratio (CCR) involves envisioning the transfer of lower branches of trees with asymmetric crowns to fill holes in the upper portion of the crown. Uncompacted crown ratio (UN(R) is measured without adjustment for holes in the crown and may be a more appropriate measurement when interest is on height to the first live branches in the crown. CCR is more commonly available because it is a standard measurement of the Forest Inventory and Analysis (FIA) program of US Forest Service, and UNCR is an optional measurement at the discretion of regional FIA units. The mean difference between UNCR and CCR of trees in the western United States (0.17 live crown) could be large enough to introduce biologically significant bias in applications that use crown ratio to derive height to crown base. Equations were developed to convert CCR to UNCR for 35 tree species in Idaho, Montana, Wyoming, Nevada, Utah, Colorado, Arizona, and New Mexico using data from the Interior West FIA unit. UNCR was modeled as a logistic function of CCR and tree diameter, and species-specific equations were fit by nonlinear regression. Root mean squared error for the regression equations ranged from 0.06 to 0.15 UNCR (mean absolute error, 0.04-0.12 UNCR). Equations for most species performed well when applied to test data that were not available at the time of model fitting.

TI Thinning Ponderosa Pine Affected by Armillaria Root Disease: 40 Years of Growth and Mortality on an Infected Site in Central Oregon SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE Pinus ponderosa; Armillaria ostoyae; stand density index ID EASTERN OREGON; DOUGLAS-FIR; ROT; OSTOYAE; FOREST; MELLEA; STUMPS; TREES AB Portions of a 30-year-old stand of ponderosa pine were precommercially thinned in 1966 and commercially thinned in 2000 at age 64 years to determine the effects of thinning from below on tree growth and mortality caused by Armillaria root disease in central Oregon. Thirty years after precommercial thinning, leave-tree mortality was significantly less in thinned plots than in unthinned plots, but leave-tree-diameter growth was not significantly increased by thinning. Leave-tree basal area (BA) per acre growth, however, was significantly greater in thinned plots. In 2007 at age 71 years, 7 years after commercial thinning of the same plots that were precommercially thinned in 1966, leave-tree mortality was less in thinned plots than in unthinned plots, but more time probably is necessary to adequately assess Armillaria-caused mortality after commercial thinning. Both tree diameter and BA growth were significantly increased by commercial thinning. Hypotheses on fungal-host dynamics are discussed, and recommendations for multiple thinning based on stand density index are given. C1 [Filip, Gregory M.] US Forest Serv, Portland, OR 97208 USA.

Individual tree crown segment attributes (height, area, and species type) were derived from the three-dimensional LIDAR point cloud, LIDAR-based canopy height models, and LIDAR return intensity information. The LIDAR-based crown segment and canopy cover information was then used to estimate condition classes at each 10-m grid cell on a 300 x 300-m area surrounding each FIA plot. A quantitative comparison of the LIDAR- and field-based condition classifications at the subplot centers indicates that LIDAR has potential as a useful sampling tool in an operational forest inventory program.

Twelve black cherry (Prunus serotina) trees that had a wide range of physical characteristics were tested in a stand of second-growth hardwoods in Kane, PA, using a PiCUS (R) Sonic Tomograph tool. The trees were felled after the field test and a disc from each sampling height was cut and subjected to laboratory evaluations. It was found that acoustic tomography underestimates heartwood decay when it is the major structural defect in the trees. However, when all internal crack is present in the tree trunk, the acoustic tomography tends to overestimate the size of the defects. In the presence of ring shake in the cross-section, the acoustic shadows resemble the influence of both extensive heartwood decay and lateral cracks. These findings highlight the importance of determining the nature of structural defects when assessing hardwood trees using the acoustic tomography technique. Results from this study offer insights that may be used to improve the interpretation algorithm embedded in the tomography software.

TI ASSESSING WOOD QUALITY OF BORER-INFESTED RED OAK LOGS WITH A RESONANCE ACOUSTIC TECHNIQUE SO WOOD AND FIBER SCIENCE LA English DT Article DE Acoustic velocity; logs; defects; grade yield; mechanical properties; oak decline; red oak; red oak borer AB Large numbers of black oak (Quercus velutina Lam.) and scarlet oak (Quercus coccinea Muenchh.) trees are declining and dying in the Missouri Ozark forest as a result of oak decline. Red oak borer-infested trees produce low-grade logs that become extremely difficult to merchandize as the level of insect attack increases. The Objective Of this Study was to investigate the use of a resonance-based acoustic technique to evaluate the wood quality of infested red oak logs before processing as measured by grade, type and location of defects, and mechanical properties of the resulting boards. principal component and canonical correlation analyses revealed that relationships do exist between log acoustic measurement and board grade yield, and between a linear combination of look acoustic velocity and diameter at breast height and a linear combination of board defect measurements. Although the acoustic technique was found capable of assessing wood quality at a stand level, the major advantage of the technique lies in segregating logs within the stand.

Karst.] sapwood, subjected to three different treatments (untreated, acetylated, and furfurylated), was studied during drying at 40 degrees C at MCs below fiber saturation. Spin-spin relaxation time distributions were derived from Carr-Purcell-Meiboom-Gill relaxation curves using mulitexponential fitting (CONTIN). After conditioning for 6 wk at 100% RH, the modified wood sample,,; had a MC of about 15%, whereas the MC of the untreated samples was about 30%. Two water populations with different relaxation times were found in all three sample types at this point: 1.1 ms and 0.15 ms (untreated), 0.5 ms and 0. 15 ms (furfurylated), and 1.2 - 3.5 ms and 0.1 ms (acetylated). As the MC decreased, the relaxation time of the most slowly relaxing population decreased, whereas it remained more or less constant for the other population. For both the untreated and the furfurylated samples, the two populations merged at 5 - 10% MC, and relaxation times were identical for the two treatments at low MC. The two populations did not merge for the acetylated samples. These results indicate that while acetylation changed the interaction between water and the wood cell wall, furfurylation seemed to mostly affect the amount of water present within the cell wall at the beginning of the drying experiment.

However, numerous barriers impede practitioners from developing concrete and enduring responses to emerging ecosystem service markets, policies, and initiatives. Principle among these barriers is that the ecosystem service concept has a complex history, numerous definitions in use, and an astounding diversity in rationale and application. This article provides a conceptual review of ecosystem services and its economic foundations, distinguishes among several current definitions of the term and their relatedness to strategies in practical application, discusses diverse approaches to valuation, and explores potential for future relevance in forest product and other sectors.

Dense forests are increasingly prone to large stand-replacing fires; yet, thinning and burning treatments, especially combined with other disturbances such as drought and grazing, may enhance populations of colonizing species, including a number of non-native species. Our study quantifies plant standing crop of major herbaceous species across contrasting stand structural types representing a range in disturbance severity in northern Arizona. The least disturbed unmanaged ponderosa pine stands had no non-native species, while non-native grasses constituted 7-11% of the understory, plant standing crop in thinned and burned stands. Severely disturbed wildfire stands had a higher proportion of colonizing native species as well as non-native species than other structural types, and areas protected from grazing produced greater standing crop of native forbs compared to grazed unmanaged stands. Standing crop of understory plants in low basal area thinned and burned plots was similar to levels on wildfire plots, but was comprised of fewer non-native graminoids and native colonizing plants. Our results also indicate that size of canopy openings had a stronger influence on standing crop in low basal area plots, whereas tree density more strongly constrained understory plant standing crop in dense stands. These results imply that treatments resulting in clumped tree distribution and basal areas <10 m(2) ha(-1) will be more successful in restoring native understory plant biomass in dense stands. Multiple types and severity of disturbances, such as thinning, burning, grazing, and drought over short periods of time can create greater abundance of colonizing species. Spreading thinning and burning treatments over time may reduce the potential for non-native species colonization compared to immediately burning thinned stands. Published by Elsevier B.V.

Such data are needed so that forest managers can make informed decisions regarding conservation of bat roosts. Our objective was to examine roost selection by nonreproductive eastern pipistrelles (Penimyotis subflavus) and red bats (Lasiurus borealis) in a dense deciduous forest undergoing low-intensity timber management in the southern Appalachian Mountains of western North Carolina, USA. During May to August 2004-2006, we radiotracked eight red bats and seven pipistrelles to roosts for 1-14 days (red bats, (x) over bar = 4.11 days, n = 19 roosts; pipistrelles, (x) over bar = 7 days, n = 15 roosts). We compared roost and random trees or points using paired-sample t-tests for tree and microhabitat characters and logistic regression models of one to three variables for macrohabitat characters. Neither red bats nor pipistrelles selected roosts based on tree or microhabitat characteristics. Red bats used a wide range of stand ages and conditions and, based on our most plausible models for macrohabitat variables, roosted closer than expected ((x) over bar = 70.6 m) to linear openings such as gated roads. Pipistrelles only used stands >= 72 years in age and roosted closer than expected ((x) over bar = 185.6 m) to nonlinear openings and at elevations lower than expected ((x) over bar = 882 m). Combined evidence of multiple variables indicated that pipistrelles preferred to roost close to streams. Our results indicate that land managers in the southern Appalachians should maintain a diversity of age classes to provide roosting habitat for both species, and that pipistrelles in particular may benefit from retention of mature stands or buffer zones near perennial streams. Furthermore, non-reproductive red bats and pipistrelles may prefer to roost near openings to minimize commuting costs when openings comprise a small proportion of a densely forested landscape.

We report here on a comparison of four restoration techniques in terms of survival, accretion of vertical structure, and woody species diversity. The range of treatment intensity allowed us to compare native recolonization to direct seeding and planting of Quercus nuttallii Palmer, and to an intensive treatment of interplanting two species that differed in successional status (early successional Populus deltoides Bartram ex Marsh. ssp. deltoides, with the mid-successional Q nuttallii). Native recolonization varied in effectiveness by block but overall provided few woody plants. All active restoration methods (planting and direct seeding) were successful in terms of stocking. Populus grew larger than Quercus, reaching canopy closure after 2 years and heights after 2 and 5 years of 6 and 12.7 m, respectively. Planted Quercus were significantly larger than direct seeded Quercus in all years, but only averaged 1.4 m in height after 5 years. Interplanting did not seem to facilitate development of the Quercus seedlings. The early success of the interplanting technique demonstrated that environmental benefits can be obtained quickly by more intensive efforts. Native recolonization can augment active interventions if limitations to dispersal distance are recognized. These results should provide landowners and managers with the confidence to use techniques of varying intensity to restore ecosystem functions. Published by Elsevier B.V.

TI Short-term impacts of nutrient manipulations on leaf gas exchange and biomass partitioning in contrasting 2-year-old Pinus taeda clones during seedling establishment SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE A(Sat); Fertilization; Genotype; Leaf gas exchange; Leaf morphology; Loblolly pine ID LOBLOLLY-PINE; NITROGEN-FERTILIZATION; CARBON-DIOXIDE; SLASH PINE; PHOTOSYNTHETIC CAPACITY; INTENSIVE MANAGEMENT; STOMATAL CONDUCTANCE; COMPETITION CONTROL; GROWTH-RESPONSES; UNITED-STATES AB We conducted a 1-year greenhouse experiment to assess the impact of nutrient manipulations on seedling growth, biomass partitioning, and leaf gas exchange between two fast growing Pinus taeda clones that differed in growth efficiency. After 1 year we observed significant treatment and treatment by clone effects on growth, biomass partitioning, and gas exchange parameters. Fertilization increased total seedling biomass 18% primarily through an increase in foliage and coarse-roots. Clones did not differ in total seedling biomass, however, clone 85 produced more stem than clone 93 leading to 37% greater stem:leaf, while clone 93 maintained more branch biomass. The logging residue treatment increased stem:leaf by 30%, but had no effect on total biomass or partitioning. Differences in leaf morphology resulted in significantly greater canopy leaf area in clone 93 than clone 85. Increased foliar N concentration from fertilization had only minor effects on specific photosynthesis under saturating light (A(Sat)), but lowered stomatal conductance (g(s)), transpiration (E), and internal to external CO2 concentration ratio (C-i/C-a) as well as improved water use efficiency (WUE) independently of genotype. When gas exchange data was scaled to the canopy level both genotypes achieved similar canopy level CO2 assimilation rates, but our data suggests they did this by different means. Although we did see a small effect of nutrient limitations in total canopy photosynthesis under saturating light (A(Canopy)), A(Sat), and total leaf area (TLA), our foliar N concentration ([N]) indicated that our level of logging residue incorporation did not cause [N] to decrease below sufficiency limits. From a practical standpoint, a better understanding of strategies for capturing and partition C may lead to better selection of clonal material, thereby, optimizing productivity.

This failure may be at least partially attributable to measurement limitations. In this study, Item Response Modeling (IRM) was used to develop new physical activity and sedentary behavior change self-efficacy scales. The validity of the new scales was compared with accelerometer assessments of physical activity and sedentary behavior. Methods: New PASE and sedentary behavior change (TV viewing, computer video game use, and telephone use) self-efficacy items were developed. The scales were completed by 714, 6th grade students in seven US cities. A limited number of participants (83) also wore an accelerometer for five days and provided at least 3 full days of complete data. The new scales were analyzed using Classical Test Theory (CTT) and IRM; a reduced set of items was produced with IRM and correlated with accelerometer counts per minute and minutes of sedentary, light and moderate to vigorous activity per day after school. Results: The PASE items discriminated between high and low levels of PASE. Full and reduced scales were weakly correlated (r = 0.18) with accelerometer counts per minute after school for boys, with comparable associations for girls. Weaker correlations were observed between PASE and minutes of moderate to vigorous activity (r = 0.09 - 0.11). The uni-dimensionality of the sedentary scales was established by both exploratory factor analysis and the fit of items to the underlying variable and reliability was assessed across the length of the underlying variable with some limitations. The reduced sedentary behavior scales had poor reliability. The full scales were moderately correlated with light intensity physical activity after school (r = 0.17 to 0.33) and sedentary behavior (r = -0.29 to -0.12) among the boys, but not for girls. Conclusion: New physical activity and sedentary behavior change self-efficacy scales have fewer items than classical test theory derived alternatives and have reasonable validity for boys, but more work is needed to develop comparable scales for girls. Fitting the items to a underlying variable could be useful in tailoring interventions to this scale. C1 [Jago, Russell] Univ Bristol, Dept Exercise Nutr & Hlth Sci, Bristol BS8 1TP, Avon, England.

Virtually no comparisons have been made for both clear and cloudy skies across multiple sites. This study evaluates the accuracy of 13 algorithms for predicting incident long-wave radiation under clear skies, ten cloud correction algorithms, and four algorithms for all-sky conditions using data from 21 sites across North America and China. Data from five research sites were combined with publicly available data from nine sites in the AmeriFlux network for initial evaluation and optimization of cloud cover estimates; seven additional AmeriFlux sites were used as an independent test of the algorithms. Clear-sky algorithms that excelled in predicting L(clr) were the Dilley, Prata, and Angstrom algorithms. Root mean square deviation (RMSD) between predicted and measured 30-minute or hourly L(clr) averaged approximately 23 W m(-2) for these three algorithms across all sites, while RMSD of daily estimates was as low as 14 W m(-2). Cloud-correction algorithms of Kimball, Unsworth, and Crawford described the data best when combined with the Dilley clear-sky algorithm. Average RMSD across all sites for these three cloud corrections was approximately 24 to 25 W m(-2) for 30-minute or hourly estimates and approximately 15 to 16 W m(-2) for daily estimates. The Kimball and Unsworth cloud corrections require an estimate of cloud cover, while the Crawford algorithm corrects for cloud cover directly from measured solar radiation. Optimum limits in the clearness index, defined as the ratio of observed solar radiation to theoretical terrestrial solar radiation, for complete cloud cover and clear skies were suggested for the Kimball and Unsworth algorithms. Application of the optimized algorithms to seven independent sites yielded similar results. On the basis of the results, the recommended algorithms can be applied with reasonable accuracy for a wide range of climates, elevations, and latitudes. C1 [Flerchinger, G.

TI Nutritive value of corn silage in mixture with climbing beans SO ANIMAL FEED SCIENCE AND TECHNOLOGY LA English DT Article DE Crude protein; Neutral detergent fiber; In vitro true digestible dry matter; Neutral detergent fiber digestibility; Lactic acid ID PROTEIN-DEGRADATION; ALFALFA SILAGE; QUALITY; FORAGE; MAIZE; YIELD; PROTEOLYSIS; LEGUMES; CLOVER AB Corn (Zea mays L.) for silage is a major forage source for dairy cows in the northern USA. It has high-energy density, but crude protein concentration is low. This study was conducted to determine the silage fiber characteristics and fermentation profile of monoculture corn or in mixture with one of three climbing beans. The experiment was conducted in two locations in 2004 and 2005. Three climbing beans, velvet bean [Mucuna pruriens (L) D.C.], 'Rongai' lablab bean [Lablab purpureus (L.) Sweet], and 'Scarlet Emperor' scarlet runner bean (Phaseolus coccineus L.) were intercropped with corn at two corn densities (82.5 and 55 thousand plants/ha). All three beans were sown at the same density (82.5 thousand plants/ha). Corn in monoculture or in mixture with bean was harvested between 1/2 and 3/4 milk line. Two 1-L glass jar mini-silos per treatment per replicate plot were filled at a density of 500 g/L, eight jars per treatment, and stored for a minimum of 45 days at room temperature (similar to 22 degrees C). At the time of ensiling a 500-g fresh sub-sample was also taken for dry matter and initial characterization of the corn and corn-bean mixtures. Each silo was analyzed for fiber characteristics, pH, and fermentation products. Silage crude protein (CP) concentration on average increased 12.6% in the mixture with the addition of any of the beans. but neutral detergent fiber (aNDF) concentration also increased 8.8%. The pH was 0.06 units greater in corn-bean mixtures than monoculture corn, and lactic acid concentration was on average 6.2% greater in the corn-bean mixtures than monoculture corn. The addition of climbing bean to corn increased CP but also had an effect on fiber concentration and fermentation profile. However, the nutritive value of corn-bean silage was similar to corn silage, indicating that corn-bean silage mixtures could be used in dairy cow rations. (C) 2008 Elsevier B.V. All rights reserved.

In particular, plant roots provide mechanical reinforcement to a soil matrix due to the different responses of soils and roots to stress. Root reinforcement is largely a function of the strength of the roots crossing potential shear planes, and the number and diameter of such roots. However, previous bank stability models have been constrained by limited field data pertaining to the spatial and temporal variability of root networks within stream banks. In this paper, a method is developed to use root-architecture data to derive parameters required for modeling temporal and spatial changes in root reinforcement. Changes in root numbers over time were assumed to follow a sigmoidal curve, which commonly represents the growth rates of organisms. Regressions for numbers of roots crossing potential shear planes over time showed small variations between species during the juvenile growth phase, but extrapolation led to large variations in root numbers by the time the senescent phase of the sigmoidal growth curve had been reached. In light of potential variability in the field data, the mean number of roots crossing a potential shear plane at each year of tree growth was also calculated using data from all species and an additional sigmoidal regression was run. After 30 years the mean number of roots predicted to cross a 1 m shear plane was 484, compared with species-specific curves whose values ranged from 240 roots for black willow trees to 890 roots for western cottonwood trees. In addition, the effect of spatial variations in rooting density with depth on stream-bank stability was modeled using the bank stability and toe erosion model (BSTEM). Three root distributions, all approximating the same average root reinforcement (5 kPa) over the top 1 m of the bank profile, were modeled, but with differing vertical distributions (concentrated near surface, non-linear decline with depth, uniform over top meter). It was found that stream-bank F, varied the most when the proportion of the failure plane length to the depth of the rooting zone was greatest. Published in 2008 by John Wiley and Sons, Ltd.

TI A root zone modelling approach to estimating groundwater recharge from irrigated areas SO JOURNAL OF HYDROLOGY LA English DT Article DE Root zone; Aquifer recharge; Irrigation; Campo de Cartagena; Water content; Pressure head ID HYDRAULIC CONDUCTIVITY; PARAMETERS; REGIONS AB In irrigated semi-arid and and regions, accurate knowledge of groundwater recharge is important for the sustainable management of scarce water resources. The Campo de Cartagena area of southeast Spain is a semi-arid region where irrigation return flow accounts for a substantial portion of recharge. In this study we estimated irrigation return flow using a root zone modelling approach in which irrigation, evapo-transpiration, and soil moisture dynamics for specific crops and irrigation regimes were simulated with the HYDRUS-1D software package. The model was calibrated using field data collected in an experimental plot. Good agreement was achieved between the HYDRUS-1D simulations and field measurements made under melon and lettuce crops. The simulations indicated that water use by the crops was below potential levels despite regular irrigation. The fraction of applied water (irrigation plus precipitation) going to recharge ranged from 22% for a summer melon crop to 68% for a fall lettuce crop. in total, we estimate that irrigation of annual fruits and vegetables produces 26 hm(3) y(-1) of groundwater recharge to the top unconfined aquifer. This estimate does not include important irrigated perennial crops in the region, such as artichoke and citrus. Overall, the results suggest a greater amount of irrigation return flow in the Campo de Cartagena region than was previously estimated. (C) 2009 Elsevier B.V. All rights reserved.

In this study, 40 crossbred pigs were intranasally inoculated with Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) and monitored for Salmonella fecal shedding and blood immune parameters at 2, 7, 14 and 20 days post-inoculation (dpi). Using a multivariate permutation test, a positive correlation was observed between Salmonella Typhimurium shedding levels at 2 and 7 dpi and serum interferon-gamma (IFN-gamma) levels at 2 dpi (p < 0.05), with Salmonella being shed in greater numbers from animals with higher IFN gamma levels. A positive correlation was also observed between IFN gamma levels and the number of banded neutrophils (2 dpi), circulating neutrophils (7 and 14 dpi), monocytes (7 dpi), and white blood cells (WBCs) (7, 14 and 20 dpi). We have further performed association studies on these immune response parameters as well as shedding status of the Salmonella-infected pigs with a single nucleotide polymorphism (SNP) in the porcine gene CCT7, previously shown by our group to be transcriptionally up-regulated in swine experimentally inoculated with Salmonella Typhimurium. Our analyses with the 40 pigs suggest a positive association (p=0.0012) of SNP genotype A/G at position AK240296.c1153G > A of the CCT7 gene with Salmonella shedding at 7 dpi compared to the G/G homozygote genotype. Linking specific genes and genetic polymorphisms with the porcine immune response to Salmonella infection and shedding may identify potential markers for carrier pigs as well as targets for disease diagnosis, intervention and prevention.

Previously we showed that glycosylation status of virulent CSFV strain Brescia E2 or E(rns) affects virus virulence. Here, the three putative glycorsylation sites of E1 were serially removed by means of site directed mutagenesis of a CSFV Brescia infectious clone (BICv) and their effect on virulence assessed in swine. Removal of all three putative glycosylation sites in E1, at CSFV positions N500, N513 and N594, yielded nonviable progeny, while single or dual site mutants excluding N594 were viable. Individual N594A (E1.N3 virus) or combined N500A/N513A (E1.N1N2 virus) substitutions resulted in BlCv attenuation. Furthermore infection with E1.N3 or E1.N1N2 viruses efficiently protected swine from challenge with virulent BlCv at 3 and 28 days post-infection. As previously observed with E(rns) and E2 and here with El data suggest that modification of glycosylation patterns could be used for developing CSFV live-attenuated vaccines.

Beef was cooked, blended to create smaller meat particles, and combined with electrolytic iron-fortified infant rice cereal. Chicken liver was cooked and blended, lyophilized, or acid-extracted, and combined with FeSO(4)-fortified wheat flour. In the beef-cereal combination, Caco-2 cell iron uptake, assessed by measuring the ferritin formed by cells, was greater when the beef was blended for the greatest amount of time (360s) compared with 30s (P<0.05). Smaller liver particles (blended for 360s or lyophilized) significantly enhanced iron uptake compared to liver blended for 60s (P<0.001) in the liver-flour combination. Compared to liver blended for 60 s, acid-extraction of liver significantly enhanced iron uptake (P=0-03) in the liver-flour combination. Homogenization of beef and homogenization, lyophilization, or acid-extraction of chicken liver increases the enhancing effect of meat products on iron absorption ill iron-fortified cereals.

The equations were developed on predominately white individuals using Siri's two-component percentage fat equation (BF%-GEN). We cross-validated the Jackson-Pollock (JP) generalised equations with samples of young white, Hispanic and African-American men and women using dual-energy X-ray absorptiometry (DXA) as the BF% referent criterion (BF%-DXA). The cross-sectional sample included 1129 women and men (aged 17-35 years). The correlations between BF%-GEN and BF%-DXA were 0.85 for women and 0.93 for men. Analysis of measurement error showed that BF%-GEN underestimated BF%-DXA of men and women by 1.3 and 3.0%. General linear models (GLM) confirmed that BF%-GEN systematically underestimated BF%-DXA of Hispanic men and women, and overestimated BF%-DXA of African-American men. GLM were used to estimate BF%-DXA from the JP sum of skinfolds and to account for race/ethnic group bias. The fit statistics (R and standard error of the estimate: SEE) of the men's calibration model were: white, R 0.92, SEE 3.0%; Hispanic, R 0.91, SEE 3.0%; African-American, R 0.95, SEE 2.6 %. The women's statistics were: white and African-American, R 0.86, SEE 3.8 %; Hispanic, R 0.83, SEE 3.4 %. These results showed that BF%-GEN and BF%-DXA were highly correlated, but the error analyses documented that the generalised equations lacked accuracy when applied to these racially and ethnically diverse men and women. The inaccuracy was linked to the body composition and race/ethnic differences between these Training Intervention and Genetics of Exercise Response (TIGER) study subjects and the men and women used to develop the generalised equations in the 1970s and using BF%-DXA as the referent criterion.

TI Evidence of a tick RNAi pathway by comparative genomics and reverse genetics screen of targets with known loss-of-function phenotypes in Drosophila SO BMC MOLECULAR BIOLOGY LA English DT Article ID DOUBLE-STRANDED-RNA; RHIPICEPHALUS BOOPHILUS MICROPLUS; FOREST-VIRUS REPLICON; SOUTHERN CATTLE TICK; CAENORHABDITIS-ELEGANS; C-ELEGANS; MAMMALIAN RNAI; CELL-LINE; IXODES-SCAPULARIS; DISTINCT ROLES AB Background: The Arthropods are a diverse group of organisms including Chelicerata (ticks, mites, spiders), Crustacea (crabs, shrimps), and Insecta (flies, mosquitoes, beetles, silkworm). The cattle tick, Rhipicephalus (Boophilus) microplus, is an economically significant ectoparasite of cattle affecting cattle industries world wide. With the availability of sequence reads from the first Chelicerate genome project (the Ixodes scapularis tick) and extensive R. microplus ESTs, we investigated evidence for putative RNAi proteins and studied RNA interference in tick cell cultures and adult female ticks targeting Drosophila homologues with known cell viability phenotype. Results: We screened 13,643 R. microplus ESTs and I. scapularis genome reads to identify RNAi related proteins in ticks. Our analysis identified 31 RNAi proteins including a putative tick Dicer, RISC associated (Ago-2 and FMRp), RNA dependent RNA polymerase (EGO-1) and 23 homologues implicated in dsRNA uptake and processing. We selected 10 R. microplus ESTs with >80% similarity to D. melanogaster proteins associated with cell viability for RNAi functional screens in both BME26 R. microplus embryonic cells and female ticks in vivo. Only genes associated with proteasomes had an effect on cell viability in vitro. In vivo RNAi showed that 9 genes had significant effects either causing lethality or impairing egg laying. Conclusion: We have identified key RNAi-related proteins in ticks and along with our loss-of-function studies support a functional RNAi pathway in R. microplus. Our preliminary studies indicate that tick RNAi pathways may differ from that of other Arthropods such as insects.

The ethyl ether/ petroleum ether extraction procedure from AOAC 992.26 was combined with the chromatographic separation and use of an internal standard (vitamin D-2) from AOAC 2002.05 to produce a method that was applicable to a variety of food samples. Results for skim milk, orange juice, breakfast cereal, salmon, a diluted USP reference standard (vitamin D-3 in peanut oil), and processed cheese are presented. Results indicated that UV detection was adequate in most cases, but the absence of interfering species must be determined in each food by mass spectrometry. Selected ion monitoring (SIM) atmospheric pressure chemical ionization (APCI) mass spectrometry (MS) was shown to produce statistically indistinguishable results compared to UV detection for the skim milk, orange juice, multigrain cereal, and salmon samples. The processed cheese exhibited interferences that precluded quantification of vitamin D-3 by UV detection, and therefore, only SIM APCI-MS data for that sample were valid.

SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE Switchgrass; saponins; biofuel; hepatic; photosensitization ID HEPATOGENOUS PHOTOSENSITIZATION; DICHOTOMIFLORUM; IDENTIFICATION; EPISMILAGENIN; SAPOGENINS; BILE AB Switchgrass (Panicurn virgatum L.) has been identified for development into an efficient and environmentally friendly biomass energy crop. A recent 5 year study demonstrated that switchgrass grown for biofuel production produced 540% more energy than what is needed to grow, harvest, and process it into cellulosic ethanol. If switchgrass is grown on a scale useful for a bioenergy source, some of the material could be used by livestock as hay or pasture. Switchgrass has been reported to cause hepatogenous photosensitization in lambs (Ovis aries) and horses (Equus caballus). In this study, a simple extraction and rapid reversed phase high-performance liquid chromatography-electrospray ionization-mass spectrometry method was developed for quantifying the major saponins in switchgrass samples. Differences in the relative concentrations of different saponins were observed between switchgrass cultivars and plant parts.

Modeled estimates of snow water equivalent (SWE) or depth were compared to observations at forest and open sites at each location. Precipitation phase and duration of above-freezing air temperatures are shown to be major influences on divergence and convergence of modeled estimates of the subcanopy snowpack. When models are considered collectively at all locations, comparisons with observations show that it is harder to model SWE at forested sites than open sites. There is no universal "best'' model for all sites or locations, but comparison of the consistency of individual model performances relative to one another at different sites shows that there is less consistency at forest sites than open sites, and even less consistency between forest and open sites in the same year. A good performance by a model at a forest site is therefore unlikely to mean a good model performance by the same model at an open site (and vice versa). Calibration of models at forest sites provides lower errors than uncalibrated models at three out of four locations. However, benefits of calibration do not translate to subsequent years, and benefits gained by models calibrated for forest snow processes are not translated to open conditions.

It is necessary to develop more molecular markers for potential use in peanut genetic research. With the development of peanut EST projects, a vast amount of available EST sequence data has been generated. These data offered an opportunity to identify SSR in ESTs by data mining. Results: In this study, we investigated 24,238 ESTs for the identification and development of SSR markers. In total, 881 SSRs were identified from 780 SSR-containing unique ESTs. On an average, one SSR was found per 7.3 kb of EST sequence with tri-nucleotide motifs (63.9%) being the most abundant followed by di-(32.7%), tetra- (1.7%), hexa- (1.0%) and penta-nucleotide (0.7%) repeat types. The top six motifs included AG/TC (27.7%), AAG/TTC (17.4%), AAT/TTA (11.9%), ACC/TGG (7.72%), ACT/TGA (7.26%) and AT/TA (6.3%). Based on the 780 SSR-containing ESTs, a total of 290 primer pairs were successfully designed and used for validation of the amplification and assessment of the polymorphism among 22 genotypes of cultivated peanuts and 16 accessions of wild species. The results showed that 251 primer pairs yielded amplification products, of which 26 and 221 primer pairs exhibited polymorphism among the cultivated and wild species examined, respectively. Two to four alleles were found in cultivated peanuts, while 3-8 alleles presented in wild species. The apparent broad polymorphism was further confirmed by cloning and sequencing of amplified alleles. Sequence analysis of selected amplified alleles revealed that allelic diversity could be attributed mainly to differences in repeat type and length in the microsatellite regions. In addition, a few single base mutations were observed in the microsatellite flanking regions. Conclusion: This study gives an insight into the frequency, type and distribution of peanut EST-SSRs and demonstrates successful development of EST-SSR markers in cultivated peanut. These EST-SSR markers could enrich the current resource of molecular markers for the peanut community and would be useful for qualitative and quantitative trait mapping, marker-assisted selection, and genetic diversity studies in cultivated peanut as well as related Arachis species. All of the 251 working primer pairs with names, motifs, repeat types, primer sequences, and alleles tested in cultivated and wild species are listed in Additional File 1.

TI Plant origin and ploidy influence gene expression and life cycle characteristics in an invasive weed SO BMC PLANT BIOLOGY LA English DT Article ID KNAPWEED CENTAUREA-DIFFUSA; SPOTTED KNAPWEED; BIOLOGICAL-CONTROL; SECONDARY METABOLITES; GENERALIST HERBIVORES; DEFENSE RESPONSES; MACULOSA; ARABIDOPSIS; POPULATIONS; RESISTANCE AB Background: Ecological, evolutionary and physiological studies have thus far provided an incomplete picture of why some plants become invasive; therefore we used genomic resources to complement and advance this field. In order to gain insight into the invasive mechanism of Centaurea stoebe we compared plants of three geo-cytotypes, native Eurasian diploids, native Eurasian tetraploids and introduced North American tetraploids, grown in a common greenhouse environment. We monitored plant performance characteristics and life cycle habits and characterized the expression of genes related to constitutive defense and genome stability using quantitative PCR. Results: Plant origin and ploidy were found to have a significant effect on both life cycle characteristics and gene expression, highlighting the importance of comparing appropriate taxonomic groups in studies of native and introduced plant species. We found that introduced populations of C. stoebe exhibit reduced expression of transcripts related to constitutive defense relative to their native tetraploid counterparts, as might be expected based on ideas of enemy release and rapid evolution. Measurements of several vegetative traits were similar for all geocytotypes; however, fecundity of tetraploids was significantly greater than diploids, due in part to their polycarpic nature. A simulation of seed production over time predicts that introduced tetraploids have the highest fecundity of the three geo- cytotypes. Conclusion: Our results suggest that characterizing gene expression in an invasive species using populations from both its native and introduced range can provide insight into the biology of plant invasion that can complement traditional measurements of plant performance. In addition, these results highlight the importance of using appropriate taxonomic units in ecological genomics investigations.

The role of dietary modification on gut bacterial populations and the possibility of such microbial population shifts related to learning and behavior is poorly understood. The purpose of this study was to examine whether shifts in bacterial diversity due to dietary manipulation could be correlated with changes in memory and learning. Five week old male CF1 mice were randomly assigned to receive standard rodent chow (PP diet) or chow containing 50% lean ground beef (BD diet) for 3 months. As a measure of memory and learning, both groups were trained and tested on a hole-board open field apparatus. Following behavioral testing, all mice were sacrificed and colonic stool samples collected and analyzed by automated rRNA intergenic spacer analysis (ARISA) and bacterial tag-encoded FIX amplicon pyrosequencing (bTEFAP) approach for microbial diversity. Results demonstrated significantly higher bacterial diversity in the beef supplemented diet group according to ARISA and bTEFAR Compared to the PP diet, the BD diet fed mice displayed improved working (P=0.0008) and reference memory (P < 0.0001). The BD diet fed animals also displayed slower speed (P < 0.0001) in seeking food as well as reduced anxiety level in the first day of testing (P=0.0004). In conclusion, we observed a correlation between dietary induced shifts in bacteria diversity and animal behavior that may indicate a role for gut bacterial diversity in memory and learning.

The West Branch is approximately 40 km long, drains a 132 km(2) watershed and is vitally important to the remnant population of Atlantic salmon (Salmo salar) and other native species. The riparian forest is comprised of relatively small trees with a mean DBH of 21 cm (SD +/- 10.92) with 56% of the trees having a DBH <20 cm. Balsam fir (Abies balsamea) and red maple (Acer rubrum) are the most common species (54%), and 75% of all trees are short-lived, small diameter species. These data suggest the riparian forest in the West Branch Sheepscot River is dominated by young forest stands, a legacy of land use. During a survey conducted in 2005, 210 pieces of large woody debris (LWD) were identified in the study reach; an average of 78 pieces km(-1). The total volume of pieces was 8.5 m(3) or 3.2 m(3) km(-1) (LWD in this study is defined as pieces >= 10 cm in diameter and >2 m in length). The mean diameter of LWD was 17 cm with 75% of all pieces having a diameter <20 cm. Most pieces were oriented parallel or nearly parallel to the channel and did not appear to influence channel morphology. In contrast, larger pieces were more often in perpendicular or nearly perpendicular orientations, and were more likely to have a pool-forming function. Overall, the reach has low levels of stable large wood, which do not have a major influence on stream habitats. (C) 2008 Elsevier B.V. All rights reserved.

Regeneration of red spruce (Picea rubens Sarg.), eastern hemlock (Tsuga canadensis (L.) Carr.), balsam fir (Abies balsamea L. Mill), and red maple (Acer rubrum L.) was quantified. Treatments included variants of selection cutting, commercial clearcutting (unregulated harvesting), and no harvesting for >50 years (reference). Area of wood substrate (wood >= Decay Class III and >= 10 cm on at least one end) was less in the commercial clearcut than in the reference; other treatments were not differentiated. Spruce and hemlock seedlings were found at higher densities on wood than paired forest floor plots of equal area, regardless of treatment. Conversely, fir and maple were less abundant on wood than forest floor plots in reference and selection treatments, but more or equally abundant on wood than forest floor plots in the commercial clearcut. These findings suggest that silvicultural treatment affects both the availability of decayed downed wood and seedling-substrate relationships, and that forest management in the Acadian Region should consider availability of downed woody material.

Sound levels and frequencies measured within intensive aquaculture systems are within the range of fish hearing, but species-specific effects of aquaculture production noise are not well defined. Field and laboratory studies have shown that fish behavior and physiology can be negatively impacted by intense sound. Therefore, chronic exposure to aquaculture production noise could cause increased stress, reduced growth rates and feed conversion efficiency, and decreased survival. The objective of this study was to provide an in-depth evaluation of the long term effects of aquaculture production noise on the growth, condition factor, feed conversion efficiency, and survival of cultured rainbow trout, Oncorhynchus mykiss. Rainbow trout were cultured in replicated tanks using two sound treatments: 117 dB re 1 mu Pa RMS which represented sound levels lower than those recorded in an intensive recycle system and 149 dB re 1 mu Pa RMS, representing sound levels near the upper limits known to occur in recycle systems. To begin the study mean fish weights in the 117 and 149 dB tanks were 40 and 39 g, respectively. After five months of exposure no significant differences were identified between treatments for mean weight, length, specific growth rates, condition factor, feed conversion, or survival (n=4). Mean final weights for the 117 and 149 dB treatments were 641 3 and 631 10 g, respectively. Overall specific growth rates were equal, i.e. 1.84 +/- 0.00 and 1.84 +/- 0.01%/day. Analysis of growth rates of individually tagged rainbow trout indicated that fish from the 149 dB tanks grew slower during the first month of noise exposure (p<0.05); however, fish acclimated to the noise thereafter. This study further suggests that rainbow trout growth and survival are unlikely to be affected over the long term by noise levels common to intensive aquaculture systems. (C) 2008 Elsevier B.V.

TI Impact of weather on off-flavour episodes at a Louisiana commercial catfish farm SO AQUACULTURE RESEARCH LA English DT Article DE aquaculture; off-flavours; geosmin; 2-methylisoborneol ID CHANNEL CATFISH; ICTALURUS-PUNCTATUS; 2-METHYLISOBORNEOL; DEPURATION; GEOSMIN AB The catfish aquaculture industry is hampered by off-flavour events that affect timely fish sales. In this study, weather data were correlated with geosmin and 2-methylisoborneol (2-MIB) levels in 21 commercial pond's water samples. Samples were collected weekly for 44 weeks. The off-flavour compounds, geosmin and 2-MIB, were quantified using gas chromatography-mass spectrometry. Weather data were collected near the catfish farm and included maximum and minimum air temperature, rainfall, average wind velocity, maximum and minimum humidity, and maximum and minimum soil temperature. Geosmin was weakly and positively correlated with air and soil temperatures, and weakly and negatively correlated with wind velocity. 2-MIB was strongly and positively correlated with air and soil temperatures, moderately and negatively correlated with wind velocity, and weakly and positively correlated with maximum humidity. There were no bivariate relationships between rainfall, minimum humidity or pond size, and levels of either off-flavour compound. Using logistic regression, the best predictors for off-flavour status based on geosmin levels included minimum soil temperature, rainfall and minimum humidity. The best predictors for off-flavour status based on 2-MIB levels included minimum soil temperature and average wind velocity. Soil temperature and rainfall were risk factors for off-flavour, while humidity and wind velocity were protective factors.

TI Changes in the concentration, biodegradability, and fluorescent properties of dissolved organic matter during stormflows in coastal temperate watersheds SO JOURNAL OF GEOPHYSICAL RESEARCH-BIOGEOSCIENCES LA English DT Article ID PRECAMBRIAN SHIELD; NEW-YORK; CHEMICAL CHARACTERISTICS; FORESTED WATERSHEDS; STREAM WATER; UPLAND PEAT; CARBON; CATCHMENT; DOC; SPECTROSCOPY AB Dissolved organic matter (DOM) transport during storms is studied because it is important in the annual watershed export budget for dissolved organic carbon (DOC). We sampled stream water from two watersheds (upland and wetland-dominated) and three subcatchments (bog, forested wetland, and mineral forest) located within the wetland-dominated watershed during a fall and summer storm to investigate changes in the magnitude and chemical quality of DOM during stormflows. Stormflow export of DOC ranged from 2.3 kg C ha(-1) in the upland watershed to 13.9 kg C ha(-1) in the bog subcatchment. Biodegradable DOC (BDOC) export for these same storms ranged from 0.6 kg C ha(-1) in the upland watershed to 4.2 kg C ha(-1) in the bog subcatchment. The percent BDOC decreased during both storms in the upland watershed, while percent BDOC increased in the three wetland streams. Parallel factor analysis (PARAFAC) modeling of fluorescence excitation-emission matrices further showed that as stream water DOM concentrations increased during stormflows in the upland watershed, the contribution of protein-like fluorescence decreased and humic-like fluorescence increased. However, the contribution of protein-like fluorescence increased and humic-like fluorescence decreased slightly in the three wetland streams. These results indicate that shifts in the biodegradability and chemical quality of DOM are different for upland and wetland watersheds. Taken together, our findings suggest stormflows are responsible for substantial export of BDOC from coastal temperate watersheds. Moreover, we found that PARAFAC modeling of fluorescent DOM is an effective tool for elucidating shifts in the quality of stream water DOM during storms.

Smith), and corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), on transgenic sweet corn, Zea mays (L.) (Poales: Poaceae), expressing a Cry1Ab toxin from Bacillus thuringiensis Berliner (Bacillales: Bacillaceae) (Bt). Overall, transgenic corn supported lower densities of both pests than did nontransgenic corn. Control of the fall armyworm was improved in both whorl-stage and tassel-stage corn by the use of either a nucleopolyhedrovirus or neem, but the greatest improvement was seen with spinosad. Only spinosad consistently reduced damage to ears, which was caused by both pest species. In general, efficacy of the spray materials did not differ greatly between transgenic and nontransgenic corn.

The soluble fractions were dialyzed using dialysis tubing (1 kDa) and the material retained inside the tubing was filtered through 10 kDa membranes to separate into fractions with molar mass of 1-10 kDa and greater than 10 kDa. The yield of solubilized material of molar mass higher than 10 kDa (47%) and 1-10 kDa (17%) obtained by sulfonation in the presence of NaOH under vacuum was greater than the yields of the treatment at the ambient pressure (43% and 2%) and also in experiments run with only KOH (40% and 5%) or NaOH (38% and 5%) at ambient pressure.

TI Epitope Characterization and Variable Region Sequence of F1-40, a High-Affinity Monoclonal Antibody to Botulinum Neurotoxin Type A (Hall Strain) SO PLOS ONE LA English DT Article AB Background: Botulism, an often fatal neuroparalytic disease, is caused by botulinum neurotoxins (BoNT) which consist of a family of seven serotypes (A-H) produced by the anaerobic bacterium Clostridium botulinum. BoNT, considered the most potent biological toxin known, is a 150 kDa protein consisting of a 100 kDa heavy-chain (Hc) and a 50 kDa light-chain (Lc). F1-40 is a mouse-derived, IgG1 monoclonal antibody that binds the light chain of BoNT serotype A (BoNT/A) and is used in a sensitive immunoassay for toxin detection. We report the fine epitope mapping of F1-40 and the deduced amino acid sequence of the variable regions of the heavy and light chains of the antibody. Methods and Findings: To characterize the binding epitope of F1-40, three complementary experimental approaches were selected. Firstly, recombinant peptide fragments of BoNT/A light-chain were used in Western blots to identify the epitope domains. Secondly, a peptide phage-display library was used to identify the specific amino acid sequences. Thirdly, the three-dimensional structure of BoNT/A was examined in silico, and the amino acid sequences determined from the phage-display studies were mapped onto the three-dimensional structure in order to visualize the epitope. F1-40 was found to bind a peptide fragment of BoNT/A, designated L1-3, which spans from T125 to L200. The motif QPDRS was identified by phage-display, and was mapped to a region within L1-3. When the three amino acids Q138, P139 and D140 were all mutated to glycine, binding of F1-40 to the recombinant BoNT/A light chain peptide was abolished. Q-138, P-139 and D-140 form a loop on the external surface of BoNT/A, exposed to solvent and accessible to F1-40 binding. Conclusions: The epitope of F1-40 was localized to a single exposed loop (beta 4, beta 5) on the Lc of BoNT. Furthermore amino acids Q138, P139 and D140 forming the tip of the loop appear critical for binding.

The experiment was conducted in two environments in 2005. 'Rongai' lablab bean and corn were intercropped at eight different planting densities; 20180, 40/0, 40/40, 40/80, 60/0, 60/40, 60/80, and 80/80 thousand corn/lablab bean plants/ha. Corn in monoculture or in mixture with bean was harvested between 1/2 and 3/4 milk line. Two I-L glass jar mini-silos per treatment per replicate plot were filled at a density of 500g/L, eight jars per treatment per location, and stored for 40 days at room temperature (similar to 22 degrees C). At the time of ensiling a 500-g fresh sub-sample was also taken for dry matter (DM) and initial characterization of the corn and corn-bean mixtures. Each silo was analyzed for fiber characteristics, pH, and fermentation products. Silage crude protein (CP) concentration was on average 17.5% (86.4 g/kg DM) greater in the mixture than monoculture corn(73.5 g/kg DM). The in vitro true digestible DM (IVTDDM) concentrations in the mixtures were on average 4.6% less (796 g/kg DM) than that of monoculture corn (834 g/kg DM), but neutral detergent fiber digestibility was not different between monoculture corn and corn-lablab mixtures (P>0.05). Lactate concentration was 21.2% higher in the corn-lablab bean mixtures (60.5 g/kg DM) than monoculture corn (49.9 g/kg DM). The contribution of the lablab bean to the mixture increased as corn planting density decreased. Thus the maximum benefits to increased CP occurred in the mixtures with the lowest corn planting densities, but those mixtures also had the greatest reductions in IVTDDM. However all treatments fermented well in spite of significant (P<0.05) differences in pH and fermentation products. Published by Elsevier B.V.

TI Effect of Free Air Carbon dioxide Enrichment (FACE) on the chemical composition and nutritive value of wheat grain and straw SO ANIMAL FEED SCIENCE AND TECHNOLOGY LA English DT Article DE FACE; Elevated CO(2); Wheat; Grain; Straw; Nutritive value; Nitrogen ID ELEVATED CO2 CONCENTRATIONS; EXPERIMENT ESPACE-WHEAT; ATMOSPHERIC CO2; LEAF-LITTER; NITROGEN CONCENTRATION; DECOMPOSITION RATES; STRESS CONDITIONS; USE EFFICIENCY; WATER-USE; QUALITY AB The global impact of an increased concentration of CO(2) in the atmosphere on plants has been studied extensively, but little information has been published on the effect of enrichment of atmospheric CO(2) on the nutritive value of grain and straw used as ruminant feeds. This paper reports the chemical composition and nutritive value of grain and straw harvested from the drought tolerant hard red spring wheat (Triticum aestivum L) variety Yecora Rojo managed with two carbon dioxide regimes (ambient, 350 mu l/l and elevated, 550 mu l/l), two rates of nitrogen application (low N: 53 kg N/ha and high N: 393 kg N/ha) grown under a water-fed (i.e., no deficit) regime. Accumulation of carbon in straw did not differ among crops grown under elevated CO(2) and low N supplementation and crops grown under ambient CO(2) with low levels of N supplementation. Increased N application increased sequestration of C (P<0.05) compared to straw from crops grown under ambient CO(2) concentration. Low levels of N application and elevated CO(2) led to straw containing similar concentrations of N to those grown under ambient CO(2) conditions. Increasing N application to crops grown Under ambient concentrations of CO(2) elevated the concentration of N (P<0.01) whereas crops at elevated concentrations of CO(2) did not accumulate N to the same extent. Differences in the non-structural carbohydrate and cell wall content reflected lie patterns for total C. No effect of increasing the concentration of CO(2) on WSC, aNDF(om), ADF(om), hemicellulose, cellulose and lignin (sa) occurred. There was a small decline (-26 g/kg; P<0.05) in the concentration of aNDF(om) in straw from crops that had received high N input, The ratio of lignin to total N was higher in straw harvested from plots with elevated CO (33.5:1) compared with ambient CO(2) (24.6:1). No changes in the total C content occurred for grain samples in response to CO(2) concentration or supplemental N fertiliser. No interaction between supply of N and CO(2) concentration occurred. Changes in the total N content of grain in response to treatments were similar to the changes observed in the straw fraction. The increases in concentration of N incorporated into grain were higher from crops grown under enriched concentrations of CO(2) (ie., +8.6 g/kg; P<0.01) than for crops grown tinder ambient supply of CO; (+3.5 g/kg; P<0.05). Differences in concentration of starch in the grain with increasing supply of N from fertiliser occurred tinder FACE conditions (P<0.05), but not for grain harvested from those grown under ambient CO(2) levels. No effect of changing concentrations Of CO(2) were observed for ADF(om), lignin (sa), cellulose and neutral detergent cellulose digestibility but concentrations of aNDF(om) (P<0.05) and hemicellulose (P<0.05) were higher in grain grown under ambient concentrations of CO(2) irrespective or supply of N to the crop. Although effects of elevated concentrations or CO(2) on grain and straw quality were expected, this poses concerns for livestock production in systems that use lower levels of agronomic inputs. Elevated concentrations of CO(2) in the ambient environment were beneficial for development of above ground biomass and grain yield as measured by thousand grain weight. However, straw and grain quality, in terms of crude protein and the crude protein to energy ratio wil be affected by increasing concentrations of CO(2) in the atmosphere, and this may lead to a reduction in the total Supply Of Crude protein in crops used by livestock.

TI Population-specific gene expression in the plant pathogenic nematode Heterodera glycines exists prior to infection and during the onset of a resistant or susceptible reaction in the roots of the Glycine max genotype Peking SO BMC GENOMICS LA English DT Article ID SOYBEAN CYST-NEMATODE; DORSAL PHARYNGEAL GLAND; DOUBLE-STRANDED-RNA; CAENORHABDITIS-ELEGANS; MELOIDOGYNE-INCOGNITA; MICROARRAY ANALYSIS; GENOME; PARASITISM; SEQUENCE; IDENTIFICATION AB Background: A single Glycine max (soybean) genotype (Peking) reacts differently to two different populations of Heterodera glycines (soybean cyst nematode) within the first twelve hours of infection during resistant (R) and susceptible (S) reactions. This suggested that H. glycines has population-specific gene expression signatures. A microarray analysis of 7539 probe sets representing 7431 transcripts on the Affymetrix (R) soybean GeneChip (R) were used to identify population-specific gene expression signatures in pre-infective second stage larva (pi-L2) prior to their infection of Peking. Other analyses focused on the infective L2 at 12hours post infection (i-L2(12h)), and the infective sedentary stages at 3days post infection (i-L2(3d)) and 8days post infection (i-L2/L3(8d)). Results: Differential expression and false discovery rate (FDR) analyses comparing populations of pi-L2 (i.e., incompatible population, NL1-RHg to compatible population, TN8) identified 71 genes that were induced in NL1-RHg as compared to TN8. These genes included putative gland protein G23G12, putative esophageal gland protein Hgg-20 and arginine kinase. The comparative analysis of pi-L2 identified 44 genes that were suppressed in NL1-RHg as compared to TN8. These genes included a different Hgg-20 gene, an EXPB1 protein and a cuticular collagen. By 12 h, there were 7 induced genes and 0 suppressed genes in NL1-RHg. By 3d, there were 9 induced and 10 suppressed genes in NL1-RHg. Substantial changes in gene expression became evident subsequently. At 8d there were 13 induced genes in NL1-RHg. This included putative gland protein G20E03, ubiquitin extension protein, putative gland protein G30C02 and beta-1,4 endoglucanase. However, 1668 genes were found to be suppressed in NL1-RHg. These genes included steroid alpha reductase, serine proteinase and a collagen protein. Conclusion: These analyses identify a genetic expression signature for these two populations both prior to and subsequently as they undergo an R or S reaction. The identification of genes like steroid alpha reductase and serine proteinase that are involved in feeding and nutritional uptake as being highly suppressed during the R response at 8d may indicate genes that the plant is targeting. The analyses also identified numerous putative parasitism genes that are differentially expressed. The 1668 genes that are suppressed in NL1-RHg, and hence induced in TN8 may represent genes that are important during the parasitic stages of H. glycines development. The potential for different arrays of putative parasitism genes to be expressed in different nematode populations may indicate how H. glycines evolve mechanisms to overcome resistance.

Non-parametric functions predict Y from scalar 'Single Index Model' transformations of X Variance functions generated estimates of the variance of Y. Three case studies, with data from the Forest Inventory and Analysis program of the U.S. Forest Service, the Finnish National Forest Inventory, and Landsat EfM+ ancillary data, demonstrate applications of the proposed estimators. Nearly unbiased k(nn) predictions of three forest attributes were obtained. Estimates of mean square error indicate that k(nn) is an attractive technique for integrating remotely-sensed and ground data for the provision of forest attribute maps and areal predictions.

TI Predicting categorical forest variables using an improved k-Nearest Neighbour estimator and Landsat imagery SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE National Forest Inventory; ik-NN; Categorical variables; Genetic algorithm ID CLASSIFICATION ACCURACY ASSESSMENT; GENETIC ALGORITHM; SATELLITE IMAGERY; INVENTORY; ATTRIBUTES; AREA; RECOGNITION; ERROR; BIAS AB The k-Nearest Neighbour (k-NN) estimation and prediction technique is widely used to produce pixel-level predictions and areal estimates of continuous forest variables such as area and volume, often by sub-categories such as species. An advantage of k-NN is that the same parameters (e.g., k-value, distance metric, weight vector for the feature space variables) can be used for all variables, whether continuous or categorical. An obvious question is the degree to which accuracy can be improved if the k-NN estimation parameters are tailored for specific variable groups such as volumes by tree species or categorical variables. We investigated prediction of categorical forest attribute variables from satellite image spectral data using k-NN with optimisation of the weight vector for the ancillary variables obtained using a genetic algorithm. We tested several genetic algorithm fitness functions, all derived from well-known accuracy measures. For a Finnish test site, the categorical forest attribute variables were site fertility and tree species dominance, and for an Italian test site, the variables were forest type and conifer/broad-leaved dominance. The results for both test sites were validated using independent data sets. Our results indicate that use of the genetic algorithm to optimize the weight vector for prediction of a single forest attribute variable had a slight positive effect on the prediction accuracies for other variables. Errors can be further decreased if the optimisation is done by variable groups. (c) 2008 Elsevier Inc. All rights reserved.

TI A two-step nearest neighbors algorithm using satellite imagery for predicting forest structure within species composition classes SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE Mulitnomial logistic regression; Discriminant analysis; Landsat; Model-based inference ID REMOTE-SENSING DATA; AVIAN COMMUNITY ORGANIZATION; THEMATIC MAPPER DATA; BRITISH-COLUMBIA; BIRD COMMUNITIES; COASTAL OREGON; ANCILLARY DATA; UNITED-STATES; HABITAT; STANDS AB Nearest neighbors techniques have been shown to be useful for predicting multiple forest attributes from forest inventory and Landsat satellite image data. However, in regions lacking good digital land cover information. nearest neighbors selected to predict continuous variables such as tree volume must be selected without regard to relevant categorical variables such as forest/non-forest. The result is that non-zero volume predictions may be obtained for pixels predicted to be non-forest, and volume predictions for pixels predicted to be forest may be erroneously small due to non-forest nearest neighbors. For users who wish to circumvent this discrepancy, a two-step algorithm is proposed in which the class of a relevant categorical variable such as land cover is predicted in the first step. and continuous variables such as volume are predicted in the second step subject to the constraint that all nearest neighbors must come from the predicted class of the categorical variable. Nearest neighbors, multinomial logistic regression, and discriminant analysis techniques were investigated for use in the first step. The results were generally similar for the three techniques, although the multinomial logistic regression technique was slightly superior. The k-Nearest Neighbors technique was used in the second step because many continuous forest inventory variables do not satisfy the distributional assumptions necessary for parametric multivariate techniques. The results for six 15-km x 15-km areas of interest in northern Minnesota, USA, indicate that areal estimates of tree volume, basal area, and density obtained from pixel predictions are comparable to plot-based estimates and estimates by conifer and deciduous classes are also comparable to plot-based estimates. When a mixed conifer/deciduous class was included, predictions for the mixed and deciduous class were confused. Published by Elsevier Inc. C1 US Forest Serv, No Res Stn, St Paul, MN USA.

TI Calibration and validation of the relative differenced Normalized Burn Ratio (RdNBR) to three measures of fire severity in the Sierra Nevada and Klamath Mountains, California, USA SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE Fire severity; Normalized Burn ratio (NBR); Composite burn index (CBI); Landsat; Canopy cover; Basal area ID REMOTELY-SENSED DATA; MAP ACCURACY ASSESSMENT; MIXED-CONIFER FOREST; CANOPY COVER; LANDSAT TM; WESTERN OREGON; NEW-MEXICO; VEGETATION; IMAGERY; AREA AB Multispectral satellite data have become a common tool used in the mapping of wildland fire effects. Fire severity, defined as the degree to which a site has been altered, is often the variable mapped. The Normalized Burn Ratio (NBR) used in an absolute difference change detection protocol (dNBR), has become the remote sensing method of choice for US Federal land management agencies to map fire severity due to wildland fire. However, absolute differenced vegetation indices are correlated to the pre-fire chlorophyll content of the vegetation occurring within the fire perimeter. Normalizing dNBR to produce a relativized dNBR (RdNBR) removes the biasing effect of the pre-fire condition. Employing RdNBR hypothetically allows creating categorical classifications using the same thresholds for fires occurring in similar vegetation types without acquiring additional calibration field data on each fire. In this paper we tested this hypothesis by developing thresholds on random training datasets, and then comparing accuracies for (1) fires that occurred within the same geographic region as the training dataset and in similar vegetation, and (2) fires from a different geographic region that is climatically and floristically similar to the training dataset region but supports more complex vegetation structure. We additionally compared map accuracies for three measures of fire severity: the composite burn index (CBI), percent change in tree canopy cover, and percent change in tree basal area. User's and producer's accuracies were highest for the most severe categories, ranging from 70.7% to 89.1%. Accuracies of the moderate fire severity category for measures describing effects only to trees (percent change in canopy cover and basal area) indicated that the classifications were generally not much better than random. Accuracies of the moderate category for the CBI classifications were somewhat better, averaging in the 50%-60% range. These results underscore the difficulty in isolating fire effects to individual vegetation strata when fire effects are mixed. We conclude that the models presented here and in Miller and Thode ([Miller, J.D. & Thode, A.E., (2007). Quantifying burn severity in a heterogeneous landscape with a relative version of the delta Normalized Burn Ratio (dNBR). Remote Sensing of Environment, 109, 66-80.]) can produce fire severity classifications (using either CBI, or percent change in canopy cover or basal area) that are of similar accuracy in fires not used in the original calibration process, at least in conifer dominated vegetation types in Mediterranean-climate California.

A column was employed to determine the transport behavior and deposition kinetics with aquifer sand over a range of ionic strengths and cell concentrations. O157:H7 was found to be more adhesive than SA1685, with calculated deposition rate coefficients higher than those of SA1685. Comprehensive cell surface characterization techniques including size, surface charge density, extracellular polymeric substance content electrophoretic mobility, and hydrophobicity analyses were conducted to explain observed transport trends. The pathogens' size and hydrophobicity were not significantly different, whereas they varied in acidity, for which O157:H7 had 19 times higher surface charge density than SA1685. Electrophoretic mobilities, in general agreement with titration analysis and column experiments, revealed SA1685 to be more negative than O157:H7. This combination of column and characterization experiments indicates that SA1685 can be transported to a greater extent than O157:H7 in groundwater environments. This study is the first comprehensive work comparing the transport behavior of two important pathogens in aquifer systems. C1 [Haznedaroglu, B. Z.; Kim, H. N.; Walker, S.

Genetic transformation of sugarcane for disease resistance holds promise but tissue culture and transformation processes produce undesirable agronomic characteristics necessitating thorough field evaluation. A 3-year sugarcane (a complex hybrid of Saccharum species) field study was conducted in Belle Glade, FL with the following objectives: (1) thoroughly evaluate the agronomic performance of two transgenic lines transformed for SCYLV resistance (6-1, 6-2) compared with parental cultivar control CP 92-1666, (2) determine level of SCYLV resistance in the transgenic lines, and (3) characterize genetic differences in the transgenic lines compared with CP 92-1666 using simple sequence repeat (SSR) genotyping. Sugarcane yields of CP 921666 were superior to both transgenic lines, as well as tissue culture (C-1) and nptII marker gene (20-1) controls, in the plant cane, first ratoon and second ratoon crops. CP 92-1666 recorded an average of 6.5-8.7 tons sucrose ha(-1) yr(-1) more than genotypes subjected to tissue culture and biolistic transformation. However, SCYLV infection rates in transgenic lines were only 0-5%, compared with 98% in CP 92-1666. Kanamycin field assays indicated that selectable marker gene nptII was stably expressed in all co-transformed lines. SSR genotyping showed 35 additional fragments to be present and 25 existing fragments absent among 6-1, 6-2, C-1 and 20-1 compared with CP 92-1666. Although all clones had unique genotypes, the four regenerated clones showed a greater genetic distance from the donor clone CP 92-1666 (mean GD 0.4) than to one another (mean GD 0.03). This study reports the first successful gene transfer of SCYLV resistance in sugarcane and the first report of variations in microsatellite repeat number associated with regeneration from embryogenic callus. Our results highlight the potential of genetic transformation methods to incorporate desirable traits into sugarcane, combined with the necessity of thorough agronomic evaluation of transgenic genotypes. Transgenic lines 6-1 and 6-2 are being used as parents in crosses designed to combine SCYLV resistance from these genotypes with agronomic characteristics of high-yielding materials.

Sorghum is commonly grown under rainfed conditions in the Southern Plains in the U.S.A. and other semi-arid regions in the world. Thus, its production is strongly affected by the availability of soil water during the growing season. Enhancing transpiration efficiency (TE), defined as biomass accumulation per unit water transpired, may be an effective approach to increasing sorghum yield in and and semi-arid regions under no or limited irrigation. In this report, we surveyed 341 sorghum accessions for variation in TE. A selection of 25 lines was used to confirm the initial survey and these accessions were studied in a greenhouse experiment over 2 years. TE in these selected lines varied from year to year; however, similar rank was observed in both studies. Several accessions with consistent high or low TE were identified. TE based on biomass production was strongly correlated with increased biomass accumulation rather than with reduced water use. Gas-exchange analysis indicated that low internal CO(2) concentration and enhanced photosynthetic capacity may be a factor accounting for the high TE in some lines: other physiological processes also contribute to the TE based on integrated biomass. The result suggests that considerable genetic variation in TE exists in the sorghum germplasm collection and that TE is strongly influenced by environment. The sorghum lines with contrasting TE may serve as an important genetic resource for identification of physiological mechanisms regulating TE and for improvement of this trait in sorghum breeding.

Soil temperatures at depths of 0, 5, 10 and 20 cm were highest in flail mowed treatment plots (up to near 45 degrees C at 5 cm depth), followed by sickle bar mowed plots (averaging 10 degrees C lower at 5 cm depth). Lowest soil temperatures were maintained in plots that were not mowed; averaging 5 degrees C lower at 5 cm depth than the sickle bar mowed plots. Increasing temperature convergence was observed below 5 cm, with the highest Microbial biomass temperature (flail mowed treatment) at 32 degrees C and the lowest (not mowed) at 27 degrees C increased significantly (P<0.05) from <100 mg C kg(-1) soil in the late spring, to >150 mg C kg(-1) in the early fall. beta-glucosidase and alkaline phosphatase activities decreased slowly throughout the experiment, and were significantly greater (P<0.05) only when comparing the not mowed treatment to both mowing treatments. Dissolved organic C (DOC) decreased sharply, perhaps due to rainfall. Similarly, soil inorganic N decreased sharply, from approximately 0.025 mg N kg(-1) soil in the not mowed plots, to approximately 0.005 mg N kg(-1) during a rainy period. Immobilization of N during rapid microbial biomass growth could also explain the decrease in inorganic N. While resin-extractable P was significantly higher in the not mowed treatment, few differences in extractable P were detected between either mowing treatment during the experiment. Standing oat residues maintained higher levels of soil enzyme activities and the lowest microbial biomass, suggesting that controlling contact of crop residues with the soil may introduce a rate limiting factor for residue decomposition. The timing of residue decomposition in this system may be delayed by leaving most of the plant biomass above the ground (i.e. not mowed or sickle bar mowed). These residue management factors may be important in controlling soil nutrient transformations and soil organic matter maintenance in subtropical climates. Published by Elsevier B.V. C1 [Zibilske, L.

The use of a soil water balance modelling approach to incorporate the effects of soil processes, in particular soil water storage, on the timing and amount of snowmelt generated streamflow, was investigated. The study was conducted in the Reynolds Mountain East (RME) watershed, a 38 ha, snowmelt-dominated watershed in southwest Idaho. Snowmelt or rainfall inputs to the soil were determined using a well established snow accumulation and melt model (Isnobal). The soil water balance model was first evaluated at a point scale, using periodic soil water content measurements made over two years at 14 sites. In general, the simulated soil water profiles were in agreement with measurements (P < 0.05) as further indicated by high R(2) values (mostly >0.85), y-intercept values near 0, slopes near 1 and low average differences between measured and modelled values. In addition, observed soil water dynamics were generally consistent with critical model assumptions. Spatially distributed simulations over the watershed for the same two years indicate that streamflow initiation and cessation are closely linked to the overall watershed soil water storage capacity, which acts as a threshold. When soil water storage was below the threshold, streamflow was insensitive to snowmelt inputs, but once the threshold was crossed, the streamflow response was very rapid. At these times there was a relatively high degree of spatial continuity of satiated soils within the watershed. Incorporation of soil water storage effects may improve estimation of the timing and amount of streamflow generated from mountainous watersheds dominated by snowmelt.

NaCl (0-6%), and temperature on pressure inactivation of hepatitis A virus (HAV) were determined. The HAV samples were treated at 400 MPa for 1 min at 5, 20, and 50 degrees C. Decreasing solution pH enhanced pressure inactivation of HAV. This enhanced inactivation effect was most evident at 20 degrees C. A baroprotective effect was observed for NaCl concentrations from 1 to 6% For example. a treatment of 400 MegaPascals (MPa) for 1 min at 50 degrees C reduced the HAV titers by 4.0, 4.1, 13 and 0.4 log plaque forming units (PFU)/ml for NaCl concentrations of 0, 1, 3, and 6%, respectively. Overall, increasing the treatment temperature enhanced pressure inactivation of HAV in the solutions. The pressure resistance of HAV in oysters was also examined. Temperature in the range of 5 to 50 degrees C did not significantly affect the pressure inactivation of HAV within oyster homogenates. It is concluded that HPP treatment of oysters at temperatures above room temperature would not provide any additional benefit for inactivation of HAV. However, the observation that HAV inactivation is enhanced in acidic matrices is information that may be useful for designing product formulations and processing parameters for high pressure processing of products such as low pH fruit juices and salsa.

Muell.-Arg.] (clone RRIM 600) trees from 11 collections in Brazil throughout 2004. Natural rubber latex particle sizes and distributions were quite similar with an average diameter around 1 mu m. Molecular weight, Wallace plasticity, and Mooney viscosity values were approximately the same for both rubbers. Fourier transform infrared spectroscopy peaks characteristic of natural rubber were observed for both Hancornia and Hevea. The measured differences in technological properties included lower values for Hancornia dry rubber content, % ash, % nitrogen, and plasticity retention index but higher value for acetone extract. Interestingly, nitrogen and protein content were much lower in Hancornia, suggesting that it may have important applications in nonallergic rubber uses. This represents the first report of lacticifer-produced low-protein natural rubber. (C) 2008 Wiley Periodicals, Inc.

TI Adapting the Water Erosion Prediction Project (WEPP) model for forest applications SO JOURNAL OF HYDROLOGY LA English DT Article DE Forest watershed; Surface runoff; Subsurface lateral flow; Soil erosion; Hydrologic modeling; WEPP ID SOIL-EROSION; INFILTRATION; INTERFACES; VEGETATION; RUNOFF; ROADS; RAIN AB There has been an increasing public concern over forest stream pollution by excessive sedimentation due to natural or human disturbances. Adequate erosion simulation tools are needed for sound management of forest resources. The Water Erosion Prediction Project (WEPP) watershed model has proved useful in forest applications where Hortonian flow is the major form of runoff, such as modeling erosion from roads, harvested units, and burned areas by wildfire or prescribed fire. Nevertheless, when used for modeling water flow and sediment discharge from natural forest watersheds where subsurface flow is dominant, WEPP (v2004.7) underestimates these quantities, in particular, the water flow at the watershed outlet. The main goal of this study was to improve the WEPP v2004.7 so that it can be applied to adequately simulate forest watershed hydrology and erosion. The specific objectives were to modify WEPP v2004.7 algorithms and subroutines that improperly represent forest subsurface hydrologic processes; and, to assess the performance of the modified model by applying it to a research forest watershed in the Pacific Northwest, USA. Changes were made in WEPP v2004.7 to better model percolation of soil water and subsurface lateral flow. The modified model, WEPP v2008.9, was applied to the Hermada watershed located in the Boise National Forest, in southern Idaho, USA. The results from v2008.9 and v2004.7 as well as the field observations were compared. For the period of 1995-2000, average annual precipitation for the study area was 954 mm. Simulated annual watershed discharge was negligible using WEPP v2004.7, and was 262 mm using WEPP v2008.9, agreeable with field-observed 275 mm. (C) 2008 Elsevier B.V. All rights reserved.
