However, in wide (102 cm) rows, one application of either formulation failed to provide season-long control of S. obtusifolia, and two applications were required to achieve season-long weed control. In narrow (51 cm) rows, one application of the fungus either in unrefined corn oil or an invert emulsion controlled S. obtusifolia an average of > 90%, and a second application was not required for season long weed control. Soybean yields in wide-row plots treated with two applications of either the fungus/corn oil or fungus/invert emulsion, or with a single application of the fungal treatments in narrow-row soybean plots, were not significantly different from weed-free control plots, or from plots treated with the herbicide chlorimuron. These results suggest that row spacing can affect mycoherbicidal efficacy of this fungus for controlling S. obtusifolia. C1 [Boyette, C.

TI Ingestion of spinosad bait GF-120 and resulting impact on adult Chrysoperla carnea (Neuroptera : Chrysopidae) SO BIOCONTROL SCIENCE AND TECHNOLOGY LA English DT Article DE non-target effects; olive fly; repellency; green lacewing; Chrysoperla carnea ID TEPHRITID FRUIT-FLY; OLIVE-ORCHARDS; DIPTERA; PARASITOIDS; REPRODUCTION; TEBUFENOZIDE; INSECTICIDE; HYMENOPTERA; TRYPTOPHAN; LONGEVITY AB The spinosad bait spray GF-120 Naturalyte F (R) (Dow AgroSciences LLC, Indianapolis, IN, USA) is widely used in commercial olives in California. Because of concern about its non-target effects on beneficial insects, we studied its impact on feeding behavior, mortality, and reproductive parameters of adult green lacewings, Chrysoperla carnea (Stephens), under laboratory conditions. Male and female feeding rate and quantity, and subsequent mortality, were compared over a 5-day period following a 24-h exposure to honey, GF-120, or the bait component (without spinosad) in two-choice and no-choice assays. All treatments were ingested equally when offered alone. Spinosad did not impart repellency or preference to GF-120 relative to the bait. Honey was preferred in choice tests with GF-120 or bait. Significant mortality occurred when GF-120 was offered alone, but was not significant when it Was offered in choice with honey or bait. In a separate assay of female longevity and reproduction, mortality rate as a function of time was similar in all treatments, except for some significantly earlier mortality due to GF-120 compared with honey. GF-120 ingestion significantly reduced fecundity compared with bait during the first week after treatment. Egg hatch was not significantly affected. The preference of adult C. carnea for food should ameliorate the potential negative effect of GF-120 on adult C. carnea mortality in the field. The laboratory study finds that GF-120 is a potentially safer choice for G. carnea than an aqueous suspension of spinosad, and provides no new evidence for definitive risk to field populations.

TI Selenium is critical for cancer-signaling gene expression but not cell proliferation in human colon Caco-2 cells SO BIOFACTORS LA English DT Article DE Selenium; colon; cancer; glutathione peroxidase; gene array ID FACTOR-BINDING PROTEIN-3; GROWTH; SELENOPROTEINS; PREVENTION; CARCINOMA; ALPHA(2)-MACROGLOBULIN; CHEMOPREVENTION; DEFICIENCY; APOPTOSIS; NUTRIENT AB Selenium (Se) is a potential anticarcinogenic nutrient, and the essential role of Se in cell growth is well recognized but certain cancer cells appear to have acquired a survival advantage under conditions of Se-deficiency. To understand the molecular basis of Se-anticancer effects at nutritional doses (nmol/L) for cultured cells, we generated Se-deficient colon Caco-2 cells by gradually reducing serum in media because serum contains a trace amount of Se. The glutathione peroxidase (GPx) activity of Se-deficient Caco-2 cells was 10.8 mU/mg protein compared to 133.6 similar to 146.3 mU/mg protein in Caco-2 cells supplemented with 500 nmol/L selenite, SeMSC or SeMet (three tested Se-chemical forms) after 7-d culture in serum free media. Interestingly, there were no detectable differences in cell growth, cell cycle progression between Se-deficient cells and cells supplemented with 500 nmol/L Se. To examine differential cancer signaling-gene expression between Se-deficient and Se-supplemented cells, we employed a cancer signal pathway-specific array assay coupled with the real time PCR analysis. Our data demonstrate that although Caco-2 cells are resistant to Se deprivation, Se may exert its anticancer property through increasing the expression of humoral defense gene (A2M) and tumor suppressor-related genes (IGFBP3, HHIP) while decreasing pro-inflammatory gene (CXC L9, HSPB2) expression.

However, one of the side effects of HPI drugs is the development of premature atherosclerosis, whose molecular pathogenesis remains unclear. Previously we have reported that alpha-tocopherol (alpha-T) normalizes CD36 overexpression induced by ritonavir treatment and reduces oxLDL uptake in THP-1 cells. Since inflammation is a major player in the pathogenesis of atherosclerosis, we hypothesized that HPI drugs, such as ritonavir, increase proinflammatory cytokines synthesis and that alpha-T supplementation counteracts this effect by suppressing proinflammatory cytokines levels. Here, we report that after differentiating THP-1 cells to macrophages, ritonavir treatment (10 mu g/mL) significantly increases expression of proinflammatory cytokines, IL-6, MCP-1 and IL-8, at both mRNA and protein levels. This ritonavir-induced effect is significantly suppressed by treatment of THP-1/macrophages with 50 mu M alpha-T. We conclude that ritonavir can induce proinflammatory cytokines synthesis in THP-1/macrophages, which might be associated with the development of premature atherosclerosis in ritonavir-treated patients and that this effect is prevented by alpha-T.

TI Scaling net ecosystem production and net biome production over a heterogeneous region in the western United States SO BIOGEOSCIENCES LA English DT Article ID DAILY SOLAR-RADIATION; PACIFIC-NORTHWEST; CARBON BUDGET; COMPLEX TERRAIN; CLIMATE-CHANGE; FOREST LANDSCAPE; EUROPEAN FORESTS; TREE MORTALITY; OREGON FORESTS; LANDSAT DATA AB Bottom-up scaling of net ecosystem production (NEP) and net biome production (NBP) was used to generate a carbon budget for a large heterogeneous region (the state of Oregon, 2.5 x 10(5) km(2)) in the western United States. Landsat resolution (30 m) remote sensing provided the basis for mapping land cover and disturbance history, thus allowing us to account for all major fire and logging events over the last 30 years. For NEP, a 23-year record (1980-2002) of distributed meteorology (1 km resolution) at the daily time step was used to drive a process-based carbon cycle model (Biome-BGC). For NBP, fire emissions were computed from remote sensing based estimates of area burned and our mapped biomass estimates. Our estimates for the contribution of logging and crop harvest removals to NBP were from the model simulations and were checked against public records of forest and crop harvesting. The predominately forested ecoregions within our study region had the highest NEP sinks, with ecoregion averages up to 197 gC m(-2)yr(-1). Agricultural ecoregions were also NEP sinks, reflecting the imbalance of NPP and decomposition of crop residues. For the period 1996-2000, mean NEP for the study area was 17.0 TgC yr(-1), with strong interannual variation (SD of 10.6). The sum of forest harvest removals, crop removals, and direct fire emissions amounted to 63% of NEP, leaving a mean NBP of 6.1 TgC yr-(1). Carbon sequestration was predominantly on public forestland, where the harvest rate has fallen dramatically in the recent years. Comparison of simulation results with estimates of carbon stocks, and changes in carbon stocks, based on forest inventory data showed generally good agreement. The carbon sequestered as NBP, plus accumulation of forest products in slow turnover pools, offset 51% of the annual emissions of fossil fuel CO(2) for the state. State-level NBP dropped below zero in 2002 because of the combination of a dry climate year and a large (200 000 ha) fire. These results highlight the strong influence of land management and interannual variation in climate on the terrestrial carbon flux in the temperate zone.

It is likely that, in cases of severe deficits in memory or motor function, hospitalization and/or custodial care would be a likely outcome. This means that unless some way is found to reduce these age-related decrements in neuronal function, healthcare costs will continue to rise exponentially. Thus, it is extremely important to explore methods to retard or reverse the age-related neuronal deficits as well as their subsequent, behavioral manifestations. Applying molecular biological approaches to slow aging in the human condition may be years away. So it is important to determine what methods can be used today to increase healthy aging, forestall the onset of these diseases, and create conditions favorable to obtaining a "longevity dividend" in both financial and human terms. In this regard, epidemiological studies indicate that consumption of diets rich in antioxidants and anti-inflammatory compounds, such as those found in fruits and vegetables, may lower the risk of developing age-related neurodegenerative diseases, such as Alzheimer's or Parkinson's diseases (AD and PD). Research suggests that the polyphenolic compounds found in fruits, such as blueberries, may exert their beneficial effects by altering stress signaling and neuronal communication, suggesting that interventions may exert protection against age-related deficits in cognitive and motor function. The purpose of this article is to discuss the benefits of these interventions in rodent models and to describe the putative molecular mechanisms involved in their benefits.

Zajecarska 83), long-term maintained on growth regulator-free medium, were histologically analyzed. In all examined cultures, somatic embryos at various stages of development were observed and secondary embryos were formed in the cotyledonary, hypocotylary and radicular region of the primary embryos. Detailed histological analysis of the torpedo shape somatic embryo revealed that secondary somatic embryos arose directly from single epidermal cells of hypocotylary axis after an unequal periclinal division. Bipolar proembryos were composed of one smaller cytoplasm rich cell and one larger more vacuolated cell. Further cell division pattern was similar for both non-transformed and transformed embryos. However, multicellular origin of secondary embryos in a direct process and even from callus can not be excluded. C1 Inst Biol Res Dr Sinisa Stankovic, Belgrade 11060, Serbia.

We tested the response of potato (Solanum tuberosum L. cv. Superior) to inoculation with AM fungi in a field with very high available P (375 mu g g(-1) soil) in two growing seasons. Inoculation treatments included a commercially available inoculum containing Glomus intraradices, mixed species inocula produced on-farm in mixtures of compost and vermiculite, and a control treatment consisting of a freshly prepared compost and vermiculite mixture. In addition, two farming systems were imposed: conventional chemical fertilizers or dairy manure composted with leaves were applied to meet recommended nutrient requirements. Yields of tubers on a fresh weight basis in the first year were increased by AM fungus inoculum, 33% under conventional fertilizer application and 45% with compost addition vs. controls in each system. The response to inoculation the second year was less; however yields of inoculated plants were 10 to 20% greater than control,.;. There was a significant positive treatment effect of inoculation upon production of larger sized potatoes in the second year. Neither year saw a marked difference in yield response among AM fungus inocula. These results demonstrate the potential yield benefits of inoculation of potatoes with AM fungi produced on the farm.

Not only do pollinating insects help to maintain a diversity of plants within forests, but they also aid in pollinating crops found near forested land. Currently, the effects of various forest management practices on floral visiting insect abundance or diversity is unknown, so we investigated how prescribed burning, mechanical shrub control, and combination of the two affected abundance of floral visiting insects. We caught 7921 floral visitors from four orders and 21 families. Hymenoptera was the most abundant and diverse order, with Halictidae being the most abundant family A total of 45 species of Hymenoptera representing six families were captured. We caught seven families and 35 species of Lepidoptera, six families and 33 species of Coleoptera, and two families and 13 species of Diptera. Most floral visitors were captured in the mechanical shrub control plus prescribed burn treatments, while lower numbers were caught on the mechanical shrub control only, prescribed burn only and control treatments. Overall species richness was also higher on mechanical plus burn treatments. Total pollinator abundance and the abundance of most orders and families was correlated with decreased tree basal area and increased percent herbaceous plant cover. Our study shows that floral visitors increased in abundance and species richness most from forest disturbance that reduced the density of overstory trees and increased the amount of herbaceous plant growth.

Feral swine damage is one of the greatest threats to this wetland habitat. We conducted a multi-year study to evaluate the impacts of sport hunting and supplemental swine removal on damage to seepage slopes. Prior to initiation of removal in 2003, swine damage to seepage slopes in the portion of the base closed to hunting averaged 25.0%, over twice the 10.9% losses in the portion open to hunting. After less than one year of supplemental removal, damage in the closed-to-hunting area dropped to 7.2%. Although supplemental removal was not applied in the open hunting area, damage dropped significantly to 5.6%, statistically indistinguishable from the swine-controlled (closed) portion. After another year of removal, average damage in the closed hunting area dropped further to 5.6%, while the open hunting area dropped to 4.3%, again statistically indistinguishable. Even though removal was only applied to the area closed to hunting, it also produced damage reductions in the open hunting area, as swine were free to move among areas. Declines in damage following implementation of removal corresponded with large drops in swine population indices for the base. Economic valuations of seepage slope damage losses demonstrated substantial benefit-cost ratios for application of removal. Prior to removal, the combined value of swine damage to seepage slopes in areas open and closed to hunting was estimated at $5.3 million. After only 1.7 years of removal, the value of damage losses was reduced by nearly $4 million to $1.5 million. The benefit-cost ratio over the 1.7 years of removal was an impressive 27.5. Moreover, the economic benefits of removal exceeded the costs 55.2-fold for the first year, when management impact would be greatest. C1 Natl Wildlife Res Ctr, Ft Collins, CO 80521 USA.

Entomopathogenic nematodes have not been previously tested against stored-product insects in environments such as empty grain bins or food processing and warehouse facilities, but their effectiveness at finding and infecting hosts in other cryptic habitats has been demonstrated. In laboratory bioassays, Steinernema riobrave reduced survival of red flour beetle, Tribolium castaneum, larvae, pupae and adults from 77.9 +/- 3.2% in the controls to 27.4 +/- 2.5% in treatments. Temperature (25 and 30 degrees C) and relative humidity (43, 56-57, 75, and 100%) did not significantly influence S. riobrave efficacy in this experiment. Field trials simulating empty grain bin treatments were conducted using red flour beetle and the Indian meal moth, Plodia interpunctella. Total survival of mixed stages (larvae, pupae and adults) of T. castaneum was 42% of that in the control and total survival of mixed stages of P. interpunctella was 27% of the control. Larval stages were the most susceptible to S. riobrave for both insect species with P. interpunctella larvae having 99% mortality and T. castaneum larvae having 80% mortality. S. riobrave shows promise as a biological control agent for stored-product insects, particularly Indian meal moth, but further studies looking at combinations of treatments may further enhance efficacy.

Treatments included: water only, 3:1 honey-water solution, floral and extra-floral nectars from five different plants (excised stems from Fagopyrum esculentum, Lobularia maritima, Phacelia tanacetifolia, Anethum graveolens and Vicia faba), honeydew from Coccus hesperidum and Homalodisca vitripennis (formally H. coagulata), a commercially available food supplement (Eliminade) and citrus foliage. Additionally, the sugar composition of each food resource was determined using HPLC and whole flower extracts. Honey-water and F esculentum nectar significantly increased longevity of male and female G. ashmeadi, G. triguttatus, and G. fasciatus up to 1860%, 1323% and 1459%, respectively, when compared with water. For both sexes and all three parasitoid species, survival on citrus foliage, H. vitripennis excrement, and P. tanacetifolia flowers was equivalent to that on water only. The longevity of G. ashmeadi and G. triguttatits was up to 539% higher on Eliminade compared with water only, however there was no significant effect of Eliminade on survival of G. fasciatus. Coccus hesperidum honeydew increased survival times up to 665% for all mymarid species compared with citrus foliage alone. HPLC analysis indicated that food resources most beneficial to Gonatocerus parasitoids possessed a high proportion of glucose (up to 44%) and fructose (up to 53%), suggesting that sucrose may not be as important for parasitoid survival. Citrus and P. tanacetifolia flowers contained favorable proportions of glucose and fructose, but the inability of Gonatocerus spp. to benefit from this may be related to flower morphology which could prevent access to nectar.

Boron trifluoride diethyl etherate was used as an initiator. Influences of polymerization temperature, amount of initiator, and carbon dioxide pressure on the molecular weight were investigated. It is shown that the higher polymerization temperature favors polymers with relatively higher molecular weights. Larger amounts of initiator also provide polymers with higher molecular weights. Higher pressure favors polymers with relatively higher molecular weights. The applications of these soy-based materials will be in the lubrication and hydraulic fluid areas.

Analogs of the insect kinin class, in which the critical residues of F-1, P-3, and W-4 were replaced with beta(3)-amino acid or their beta(2)-homo-amino acid variants, have been synthesized by the solid phase peptide strategy. The resulting single-and double- replacement analogs were evaluated in an insect diuretic assay and enzyme digestion trials. Analogs modified in the core P3 position produce a potent and efficacious diuretic response that is not significantly different from that obtained with the endogenous achetakinin peptides. The analogs also demonstrate enhanced resistance to hydrolysis by ACE and NEP, endopeptidases that inactivate the natural insect neuropeptides. This paper describes the first instance of beta-amino acids analogs of an antropod peptide that demonstrate significant bioactivity and resistance to peptidase degradation.

TI Composting rapidly reduces levels of extractable oxytetracycline in manure from therapeutically treated beef calves SO BIORESOURCE TECHNOLOGY LA English DT Article DE oxytetracycline; composting; manure; antibiotic; calf ID MARINE-SEDIMENTS; VETERINARY ANTIBIOTICS; SOIL; WATER; RESIDUES; TETRACYCLINE; PERSISTENCE; TYLOSIN; METRONIDAZOLE; DEGRADATION AB Oxytetracychne (OTC) is a broad-spectrum antibiotic used in livestock production. The widespread use and relative persistence of OTC may encourage development of antibiotic-resistant bacteria. The objective of this study was to determine whether composting would substantially reduce the concentration of OTC found in manure from medicated animals. The effect of OTC on composting was also investigated. Five beef calves were medicated for 5 days with 22 mg/kg/day of OTC. Approximately 23% of the OTC fed to the calves was recovered in the manure. Manure samples collected from calves prior to and after medication were mixed with straw and woodchips, and aliquots of the subsequent mixtures were treated in laboratory composters for 35 days. In addition, aliquots of the OTC-containing mixture were incubated at 25 degrees C or sterilized followed by incubation at 25 degrees C. The presence of OTC did not appear to affect composting processes. Within the first six days of composting, levels of extractable OTC in the compost mixture decreased from 115 +/- 8 mu g/g dry weight to less than 6 +/- 1 mu g/g dry weight (a 95% reduction). In contrast, levels of extractable OTC in room temperature incubated and sterilized mixtures decreased only 12-25% after 37 and 35 days, respectively. Levels of total heterotrophic bacteria and OTC-resistant bacteria in the finished compost mixture were roughly 30-fold higher and 10-fold lower, respectively, than levels in the mixture prior to composting. Although the basis of the OTC disappearance during composting is not known, the preponderence of OTC-sensitive bacteria and the decrease of OTC-resistant bacteria in the finished compost suggests that OTC residues have been rendered biologically inactive or unavailable.

The RNA polymerases involved in viroid replication - DNA-dependent RNA polymerase II or a nuclear-encoded chloroplastic RNA polymerase - are entirely host-encoded, and the absence of viroid-encoded polypeptides strongly suggests that the subsequent cell-to-cell and long-distance movement of progeny is also completely dependent on normal host cell pathways. Recent studies with potato spindle tuber viroid (PSTVd) have identified specific structural features that are involved in: (i) cleavage or ligation of replicative intermediates; and (ii) transport of viroid progeny across tissue boundaries. Significant progress has also been made in unraveling the molecular mechanism(s) of viroid pathogenesis, in particular, the possible role of viroid-induced RNA silencing in disrupting host gene expression. The availability of detailed information regarding host contributions to the disease process has provided new opportunities to target disruption of specific events in the viroid replication cycle. Plants that are resistant or immune to infection can be used to augment the diagnostic testing and seed or nursery stock certification schemes currently used to control viroid diseases.

This review describes the proactive development of the transgenic papaya and its impact on stemming the destruction caused by PRSV in Puna, the main papaya producing area in Hawaii. It also focuses on the regulatory issues that were confronted in obtaining approval from the US government's Environmental Protection Agency (EPA), Animal Plant Health Inspection Service (APHIS) and Food and Drug Administration (FDA). The performance of the transgenic papaya is traced over the last 8 years following commercial release, with special observations on the issues of environmental impact and coexistence with non-transgenic papaya. The latter is quite important since a significant part of Hawaii's papaya is exported to Canada and Japan. Canada has approved the transgenic papaya, but efforts to get approval for export of transgenic papaya to Japan are still ongoing. C1 [Suzuki, J.

Our research aims to improve understanding of plant defense against aphid, a major pest on many cereal crops. In this study, transcriptome of sorghum in response to greenbug feeding was investigated with micro-arrays carrying thousands of cDNA clones from the SSH libraries of plants treated by greenbug aphid. Analysis of genome-wide transcriptional regulation allowed the discovery of all defense-related genes and these resultant expression profiles helped in elucidating their function. These data showed that phloem-feeding induced defense response pathways associated with both aphid attack and pathogen infection and indicated signaling pathways were partially overlapping among plant responses to pathogens, insects, and wounding.

This study investigated the generation of hydrogen peroxide by hydrodynamically stressed cultures of Morinda citrifolia, over a 5-h period post-stress imposition. Suspensions were exposed to repeated passages through a syringe, under laminar flow conditions, corresponding to cumulative energy dissipation levels of approximately 3-6 J kg(-1). Extracellular hydrogen peroxide was detected using a luminol-based chemiluminescence assay. The addition of exogenous hydrogen peroxide facilitated the detection of low levels of hydrogen peroxide in the presence of antioxidants. Immediately after shear exposure, there was evidence of significant antioxidative capacity in the sheared cell cultures, which potentially masked any oxidative burst (OB), but which decreased over the following 40 min. This antioxidative capacity was determined to derive from the shearing process. Trials in which ground cellular debris was added to control suspensions suggested that some of the antioxidative capacity observed in stressed suspensions was directly associated with debris generated by the shearing process. Using UV-vis spectrophotometry and HPLC, stress-related increases in the levels of phenolic compounds were detected in suspension filtrates. Under the stress conditions investigated, maximum hydrogen peroxide levels of 11.5 mu M were observed, 5 h after shear exposure. This study emphasizes the importance of considering both oxidative and antioxidative capacities as part of a holistic approach to the determination of the OB in hydrodynamically stressed plant cell suspension cultures.

Nanduri, Bindu TI ProtQuant: a tool for the label-free quantification of MudPIT proteomics data SO BMC BIOINFORMATICS LA English DT Article ID SUBMINIMUM INHIBITORY CONCENTRATIONS; MISSING VALUE IMPUTATION; MASS-SPECTROMETRY; PROTEIN IDENTIFICATION; MICROARRAY DATA; SEARCH; EXPRESSION; ABUNDANCE; PEPTIDES; MODEL AB Background: Effective and economical methods for quantitative analysis of high throughput mass spectrometry data are essential to meet the goals of directly identifying, characterizing, and quantifying proteins from a particular cell state. Multidimensional Protein Identification Technology (MudPIT) is a common approach used in protein identification. Two types of methods are used to detect differential protein expression in MudPIT experiments: those involving stable isotope labelling and the so-called label-free methods. Label-free methods are based on the relationship between protein abundance and sampling statistics such as peptide count, spectral count, probabilistic peptide identification scores, and sum of peptide Sequest XCorr scores (Sigma XCorr). Although a number of label-free methods for protein quantification have been described in the literature, there are few publicly available tools that implement these methods. We describe ProtQuant, a Java-based tool for label-free protein quantification that uses the previously published Sigma XCorr method for quantification and includes an improved method for handling missing data. Results: ProtQuant was designed for ease of use and portability for the bench scientist. It implements the Sigma XCorr method for label free protein quantification from MudPIT datasets. ProtQuant has a graphical user interface, accepts multiple file formats, is not limited by the size of the input files, and can process any number of replicates and any number of treatments. In addition, ProtQuant implements a new method for dealing with missing values for peptide scores used for quantification. The new algorithm, called Sigma XCorr*, uses "below threshold" peptide scores to provide meaningful non-zero values for missing data points. We demonstrate that Sigma XCorr* produces an average reduction in false positive identifications of differential expression of 25% compared to Sigma XCorr. Conclusion: ProtQuant is a tool for protein quantification built for multi-platform use with an intuitive user interface. ProtQuant efficiently and uniquely performs label-free quantification of protein datasets produced with Sequest and provides the user with facilities for data management and analysis. Importantly, ProtQuant is available as a self-installing executable for the Windows environment used by many bench scientists. C1 [Bridges, Susan M.; Magee, G.

Dai, Ho-Kwok TI A survey of DNA motif finding algorithms SO BMC BIOINFORMATICS LA English DT Article AB Background: Unraveling the mechanisms that regulate gene expression is a major challenge in biology. An important task in this challenge is to identify regulatory elements, especially the binding sites in deoxyribonucleic acid (DNA) for transcription factors. These binding sites are short DNA segments that are called motifs. Recent advances in genome sequence availability and in high-throughput gene expression analysis technologies have allowed for the development of computational methods for motif finding. As a result, a large number of motif finding algorithms have been implemented and applied to various motif models over the past decade. This survey reviews the latest developments in DNA motif finding algorithms. Results: Earlier algorithms use promoter sequences of coregulated genes from single genome and search for statistically overrepresented motifs. Recent algorithms are designed to use phylogenetic footprinting or orthologous sequences and also an integrated approach where promoter sequences of coregulated genes and phylogenetic footprinting are used. All the algorithms studied have been reported to correctly detect the motifs that have been previously detected by laboratory experimental approaches, and some algorithms were able to find novel motifs. However, most of these motif finding algorithms have been shown to work successfully in yeast and other lower organisms, but perform significantly worse in higher organisms. Conclusion: Despite considerable efforts to date, DNA motif finding remains a complex challenge for biologists and computer scientists. Researchers have taken many different approaches in developing motif discovery tools and the progress made in this area of research is very encouraging. Performance comparison of different motif finding tools and identification of the best tools have proven to be a difficult task because tools are designed based on algorithms and motif models that are diverse and complex and our incomplete understanding of the biology of regulatory mechanism does not always provide adequate evaluation of underlying algorithms over motif models.

Many systemic biomarker concentrations are heritable phenotypes. Genome-wide association studies ( GWAS) provide mechanisms to investigate the genetic contributions to biomarker variability unconstrained by current knowledge of physiological relations. Methods: We examined the association of Affymetrix 100K GeneChip single nucleotide polymorphisms ( SNPs) to 22 systemic biomarker concentrations in 4 biological domains: inflammation/oxidative stress; natriuretic peptides; liver function; and vitamins. Related members of the Framingham Offspring cohort ( n = 1012; mean age 59 +/- 10 years, 51% women) had both phenotype and genotype data ( minimum-maximum per phenotype n = 507-1008). We used Generalized Estimating Equations ( GEE), Family Based Association Tests ( FBAT) and variance components linkage to relate SNPs to multivariable-adjusted biomarker residuals. Autosomal SNPs ( n = 70,987) meeting the following criteria were studied: minor allele frequency >= 10%, call rate >= 80% and Hardy-Weinberg equilibrium p >= 0.001. Results: With GEE, 58 SNPs had p < 10(-6): the top SNPs were rs2494250 ( p = 1.00* 10(-14)) and rs4128725 ( p = 3.68* 10(-12)) for monocyte chemoattractant protein-1 ( MCP1), and rs2794520 ( p = 2.83* 10(-8)) and rs2808629 ( p = 3.19* 10(-8)) for C-reactive protein ( CRP) averaged from 3 examinations ( over about 20 years). With FBAT, 11 SNPs had p < 10(-6): the top SNPs were the same for MCP1 ( rs4128725, p = 3.28* 10(-8), and rs2494250, p = 3.55* 10(-8)), and also included B-type natriuretic peptide ( rs437021, p = 1.01* 10(-6)) and Vitamin K percent undercarboxylated osteocalcin ( rs2052028, p = 1.07* 10(-6)). The peak LOD ( logarithm of the odds) scores were for MCP1 ( 4.38, chromosome 1) and CRP ( 3.28, chromosome 1; previously described) concentrations; of note the 1.5 support interval included the MCP1 and CRP SNPs reported above ( GEE model). Previous candidate SNP associations with circulating CRP concentrations were replicated at p < 0.05; the SNPs rs2794520 and rs2808629 are in linkage disequilibrium with previously reported SNPs. GEE, FBAT and linkage results are posted at http://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?id=phs000007. Conclusion: The Framingham GWAS represents a resource to describe potentially novel genetic influences on systemic biomarker variability.

Genome-wide association is a promising approach to map genetic loci related to these heritable phenotypes. Methods: In 1087 Framingham Heart Study Offspring cohort participants ( mean age 47 years, 52% women), we conducted genome-wide analyses ( Affymetrix 100K GeneChip) for fasting blood lipid traits. Total cholesterol, HDL-C, and TG were measured by standard enzymatic methods and LDL-C was calculated using the Friedewald formula. The long-term averages of up to seven measurements of LDL-C, HDL-C, and TG over a similar to 30 year span were the primary phenotypes. We used generalized estimating equations ( GEE), family-based association tests ( FBAT) and variance components linkage to investigate the relationships between SNPs ( on autosomes, with minor allele frequency >= 10%, genotypic call rate >= 80%, and Hardy-Weinberg equilibrium p >= 0.001) and multivariable-adjusted residuals. We pursued a three-stage replication strategy of the GEE association results with 287 SNPs ( P < 0.001 in Stage I) tested in Stage II ( n similar to 1450 individuals) and 40 SNPs ( P < 0.001 in joint analysis of Stages I and II) tested in Stage III ( n similar to 6650 individuals). Results: Long-term averages of LDL-C, HDL-C, and TG were highly heritable ( h(2) = 0.66, 0.69, 0.58, respectively; each P < 0.0001). Of 70,987 tests for each of the phenotypes, two SNPs had p < 10(-5) in GEE results for LDL-C, four for HDL-C, and one for TG. For each multivariable-adjusted phenotype, the number of SNPs with association p < 10(-4) ranged from 13 to 18 and with p < 10(-3), from 94 to 149. Some results confirmed previously reported associations with candidate genes including variation in the lipoprotein lipase gene ( LPL) and HDL-C and TG ( rs7007797; P = 0.0005 for HDL-C and 0.002 for TG). The full set of GEE, FBAT and linkage results are posted at the database of Genotype and Phenotype (dbGaP). After three stages of replication, there was no convincing statistical evidence for association ( i.e., combined P < 10(-5) across all three stages) between any of the tested SNPs and lipid phenotypes. Conclusion: Using a 100K genome-wide scan, we have generated a set of putative associations for common sequence variants and lipid phenotypes. Validation of selected hypotheses in additional samples did not identify any new loci underlying variability in blood lipids. Lack of replication may be due to inadequate statistical power to detect modest quantitative trait locus effects ( i.e., < 1% of trait variance explained) or reduced genomic coverage of the 100K array. GWAS in FHS using a denser genome-wide genotyping platform and a better-powered replication strategy may identify novel loci underlying blood lipids.

The most widespread and notorious cases have been introductions of Caulerpa taxifolia, which now infests over 20,000 ha of Mediterranean subtidal zones. Few attempts to control seaweed invasions have been successful, due to often harsh and highly variable physical conditions in marine environments, and the lack of efficacious methods. Use of heat, copper, chlorine, salt, freshwater and various mechanical (removal) approaches have been successful in reducing or eradicating some infestations. Biological control by herbivorous mollusks and sea urchins has been investigated, but has yet to result in any operational programs. Nutrient inputs from near-shore sources have exacerbated the spread of some species (e.g., off the Florida coast). To counter the increase in seaweed introductions and the spread of these species, it will be useful to adapt, where feasible, methods that have proven successful in controlling freshwater weeds. New methods will need to be developed as well. This will require better communication among researchers and managers working to reduce introductions and negative impacts of these seaweeds.

This is due in part to the non-unique relationship between the so-called aerodynamic temperature, which relates to the efficiency of heat exchange between the land surface and overlying atmosphere, and a surface temperature measurement from a thermal-infrared radiometer, which largely corresponds to a weighted soil and canopy temperature as a function of radiometer viewing angle. A number of studies over the past several years using multi-source canopy models and/or experimental data have developed simplified methods to accommodate radiometric-aerodynamic temperature differences in one-source approaches. A recent investigation related the variability in the radiometric-aerodynamic relation to solar radiation using experimental data from a variety of landscapes, while another used a multi-source canopy model combined with measurements over a wide range in vegetation density to derive a relationship based on leaf area index. In this study, simulations by a detailed multi-source soil-plant-environment model, Cupid, which considers both radiative and turbulent exchanges across the soil-canopy-air interface, are used to explore the radiometric-aerodynamic temperature relations for a semi-arid shrubland ecosystem under a range of leaf area/canopy cover, soil moisture and meteorological conditions. The simulated radiometric-aerodynamic temperatures indicate that, while solar radiation and leaf area both strongly affect the magnitude of this temperature difference, the relationships are non-unique, having significant variability depending on local conditions. These simulations also show that soil-canopy temperature differences are highly correlated with variations in the radiometric-aerodynamic temperature differences, with the slope being primarily a function of leaf area. This result suggests that two-source schemes with reliable estimates of component soil and canopy temperatures and associated resistances may be better able to accommodate variability in the radiometric-aerodynamic relation for a wider range in vegetated canopy cover conditions than is possible with one-source schemes. However, comparisons of sensible heat flux estimates with Cupid using a simplified two-source model and a one-source model accommodating variability in the radiometric-aerodynamic relation based on vegetation density gave similar scatter. On the other hand, with experimental data from the shrubland site, the two-source model generally outperformed the one-source scheme. Clearly, vegetation density/leaf area has a major effect on the radiometric-aerodynamic temperature relation and must be considered in either one-source or two-source formulations. Hence these adjusted one-source models require similar inputs as in two-source approaches, but provide as output only bulk heat fluxes; this is not as useful for monitoring vegetation conditions.

We examined the effects of dietary cis 9, trans 11-CLA (c9, t11-CLA) and 00, c12-CLA on the expression of hepatic genes for fatty acid metabolism. Female mice, 8 weeks old, (six animals per group) were fed either a control diet or diets supplemented with 0-5 % c9, t11- or t10, c12-CLA for 8 weeks. DNA microarray analysis showed that t10, c12-CLA increased the expression of 278 hepatic genes and decreased those of 121 genes (> 2-fold); c9, t11-CLA increased expression of twenty-two genes and decreased those of nine. Real-time PCR confirmed that 00, c12-CLA reduced by the expression of fatty acid oxidation genes including flavin monooxygenase (FMO)-3 95%, cytochrome P450 (cyt P450) 69%, carnitine palmitoyl transferase 1a 77%, acetyl CoA oxidase (ACOX) 50% and PPAR alpha 65 %; it increased the expression of fatty acid synthase by 3-5-fold (P < 0.05 for all genes, except ACOX P= 0.08). It also reduced the enzymatic activity of hepatic microsomal FMO by 40% and the FMO3 specific protein by 67%. c9, t11-CLA reduced FM03 and cyt P450 expression by 61% (P=0.001) and 38 % (P=0.06) and increased steoryl CoA desaturase transcription by 5.9-fold (P=0.07). Both decreased fatty acid oxidation and increased fatty acid synthesis seem to contribute to the CLA-induced fatty liver. Since FMO and cyt P450 are also involved in drug detoxification, suppression of the transcription of these genes by CLA may have other health consequences besides development of fatty liver.

Currently there remains contradictory information on the localisation and possible role of alkaline phosphatase ( AP) in the chicken and Japanese quail oviducts. 2. Using turkeys with a hard- shelled egg in their uteri, vaginal and uterovaginal junction mucosae were stretched and fixed as whole mounts prior to the histochemical localisation of AP activity. 3. Scattered AP reactive cells were observed in the vaginal and uterovaginal junction surface epithelia and intense AP reactivity of the sperm-storage tubule ( SST) epithelium, localised to its apical border. 4. We suggest that such AP reactivity in hens in egg production may reflect cell differentiation and proliferation in the vagina and SST and possibly a mechanism for the transfer of lipid from the SST epithelia to resident sperm.

TI Development of skeletal deformities in a Streptococcus agalactiae-challenged male Nile tilapia (Oreochromis niloticus) broodfish and in its offspring SO BULLETIN OF THE EUROPEAN ASSOCIATION OF FISH PATHOLOGISTS LA English DT Article ID EFFICACY; VACCINE; AUREA; INIAE; FISH AB After injection challenge with Streptococcus agalactiae, a male Nile tilapia, Oreochromis niloticus, exhibited an erratic corkscrew swimming pattern and assumed a behavioral "C"-shaped body posture. The fish did not die after challenge but developed a grossly-observable "hunchback" at the level of the cervical spine. Radiographs revealed multiple spinal curvatures along the length of the spinal column with vertebral lordosis and kyphosis. The male fish also developed a cranial cavitation on the dorsal aspect of the head, forming a depression between the eyes. The fish subsequently mated and helped produce fry that initially appeared normal. The fry population soon experienced high mortalities, and moribund fish exhibited reddened gills, presumptively over-inflated bladders, and spun on their longitudinal axis, often with their head pointed down (tail-up swimming). Surviving fry had deformed gill opercula, cranial cavitation, and/or stunted or absent fins, but did not show vertebral deformities. Gram-positive bacteria identified as S. agalactiae were isolated from the fry but not from the male broodfish. However subclinical streptococcal infections sometimes may not be confirmed by standard microbiological techniques, and the male fish most likely transmitted S. agalactiae through water-borne horizontal or fertilization-associated vertical transmission. Streptococcus agalactiae appears to be a direct (i.e. bacterial disease pathogenesis) or indirect (i.e. intestinal nutrient malabsorption) causative factor of these skeletal anomalies among the male broodfish and the fry. This is the first case report description of skeletal abnormalities, such as scoliosis, kyphosis, cranial cavitation, deformed gill opercula, and stunted or absent fins, in S. agalactiae-infected fish.

TI The response of Dendroctonus valens and Temnochila chlorodia to Ips paraconfusus pheromone components and verbenone SO CANADIAN ENTOMOLOGIST LA English DT Article ID RED TURPENTINE BEETLE; REPUBLIC-OF-CHINA; HOST KAIROMONES; COLEOPTERA; SCOLYTIDAE; ATTRACTION; INTERRUPTION; PREDATOR; ATTACK AB The red turpentine beetle, Dendroctonus valens LeConte, 1860 (Coleoptera: Curculionidae, Scolytinae), is a common bark beetle found throughout much of North America and China. In 2004, we observed that attack densities of the California fivespined ips, Ips paraconfusus Lanier, 1970 (Coleoptera: Curculionidae, Scolytinae), in logging debris were inversely related to D. valens attacks on freshly cut stumps, which led to the demonstration that components of the aggregation pheromone of I. paraconfusus inhibited the response of D. valens to attractant-baited traps. In this study, we test the response of D. valens and Temnochila chlorodia (Mannerheim, 1843) (Coleoptera: Trogositidae), a common bark beetle predator, to racemic ipsenol, racemic ipsdienol, and (-)-cis-verbenol (IPSR) in the presence and absence of two release rates of (-)-verbenone. The addition of a relatively low release rate of (-)-verbenone (4 mg/24 h) to attractant-baited traps did not affect catch and had no significant effect on the response of D. valens to IPSR. IPSR significantly reduced D. valens attraction to baited traps. The addition of high release rates of (-)-verbenone (50 mg/24 h) to IPSR significantly increased inhibition; however, the effect was not significantly different from that observed with (-)-verbenone alone (50 mg/24 h). Temnochila chlorodia was attracted to traps baited with (-)-beta-pinene, (+)-3-carene, and (+)-alpha-pinene. The addition of (-)-verbenone (50 mg/24 h) significantly increased attraction. Traps baited with IPSR caught significantly more T chlorodia than those baited with (-)-verbenone. Few other beetles were collected. We are hopeful that these results will help facilitate the development of an effective tool for protecting Pinus spp. from D. valens infestations.

TI Role of burning season on initial understory vegetation response to prescribed fire in a mixed conifer forest SO CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE LA English DT Article ID PONDEROSA PINE FORESTS; SIERRA-NEVADA; SOIL TEMPERATURES; DORMANT-SEASON; FUEL CONSUMPTION; BLUE MOUNTAINS; TREE MORTALITY; GROWING-SEASON; GAMBEL OAK; FINE-ROOT AB Although the majority of fires in the western United States historically occurred during the late summer or early fall when fuels were dry and plants were dormant or nearly so, early-season prescribed burns are often ignited when fuels are still moist and plants are actively growing. The purpose of this study was to determine if burn season influences postfire vegetation recovery. Replicated early-season burn, late-season burn, and unburned control units were established in a mixed conifer forest, and understory vegetation was evaluated before and after treatment. Vegetation generally recovered rapidly after prescribed burning. However, late-season burns resulted in a temporary but significant drop in cover and a decline in species richness at the 1 m(2) scale in the following year. For two of the several taxa that were negatively affected by burning, the reduction in frequency was greater after late-season than early-season burns. Early-season burns may have moderated the effect of fire by consuming less fuel and lessening the amount of soil heating. Our results suggest that, when burned under high fuel loading conditions, many plant species respond more strongly to differences in fire intensity and severity than to timing of the burn relative to stage of plant growth.

TI Apical dominance and apical control in multiple flushing of temperate woody species SO CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE LA English DT Article ID DOUGLAS-FIR SEEDLINGS; PETRAEA MATT LIEBL; BUD DEVELOPMENT; SHOOT GROWTH; CYTOKININ APPLICATION; BRANCH PRODUCTION; AXILLARY BUDS; LONG SHOOTS; FOREST TREE; STEM FORM AB In young plants of many woody species, the first flush of growth in the spring may be followed by one or more flushes of the terminal shoot if growing conditions are favorable. The occurrence of these additional flushes may significantly affect crown form and structure. Apical dominance (AD) and apical control (AC) are thought to be important control mechanisms in this developmental response. A two-phase AD - AC hypothesis for the factors controlling a subsequent flush is presented and evaluated on the basis of currently known studies. The first, very early phase of this additional flush consists of budbreak and the very beginning of outgrowth of the newly formed current buds on the first flushing shoot. There is evidence that this response often involves the release of AD, which is significantly influenced by the auxin:cytokinin ratio as well as by other signals including nutrients and water. This first phase is immediately followed by a second phase, which consists of subsequent bud outgrowth under the influence of apical control. Although definitive data for hormone involvement in this latter process is sparse, there is some evidence suggesting nutritional mechanisms linked to possible hormone activity. Stem-form defects, a common occurrence in multiple-flushing shoots, are analyzed via the AD - AC hypothesis with suggestions of possible means of abatement.

Our understanding of the controls on C allocation to coarse-root growth is rudimentary, but it has important implications for projecting belowground net primary production responses to global change. Age-related changes in C allocation to coarse roots represent a critical uncertainty for modeling landscape-scale C storage and cycling. We used a 55 year chronosequence approach with complete above- and below-ground harvests to assess the effects of stand development on biomass partitioning in red pine (Pinus resinosa Ait.), a commercially important pine species. Averaged within site, individual-tree root/shoot ratios were dynamic across stand development, changing from 0.17 at 2-, 3-, and 5-year-old sites, to 0.80 at the 8-year-old site, to 0.29 at the 55-year-old site. The results of our study suggest that a current research challenge is to determine the generality of patterns of root-shoot biomass partitioning through stand development for both coniferous and hardwood forest types, and to document how these patterns change as a function of stand age, tree size, environment, and management.

Six primer-pair combinations of amplified fragment length polymorphism were used and a total of 782 polymorphic markers were generated. Cluster analysis showed that R graminis f. sp. tritici and P. graminis f. sp. secalis were distinctly different from P. hordei. The P. hordei isolates were clustered into five groups: group I contained a single, rare isolate that was virulent on all resistance genes except Rph13 and Rph15; group II contained a single isolate found to be virulent on the resistance gene Rph15; group III contained 2 isolates; group IV contained 24 isolates, 11 front the United States and 13 from diverse locations around the world; and group V contained 17 isolates, 7 from California, 7 from other states of United States, and 3 from central Europe. The study revealed that molecular diversity in P. hordei can be associated with virulence, but not well with geographic origin. C1 N Dakota State Univ, Dept Plant Pathol, Fargo, ND 58105 USA.

TI Characterizing sugarbeet varieties for postharvest storage losses is complicated by environmental effects and genotype x environment interactions SO CANADIAN JOURNAL OF PLANT SCIENCE LA English DT Article DE Beta vulgaris L.; respiration; glucose; fructose; extractable sucrose ID REGISTRATION; ROOTS; ROT AB Each year millions of tons of sugarbeet (Beta vulgaris L.) roots are stored in large exposed piles prior to processing. During postharvest storage, respiration and invert sugar formation consume sucrose and even a small reduction in these losses would have substantial economic impact. This study investigated the relative importance of hybrid, environment, and hybrid x environment interactions and examined their implications in characterizing hybrids for sucrose loss during storage or developing hybrids with improved storage properties. Glucose, fructose, and extractable sucrose concentrations and respiration rate were measured 30 and 120 d after harvest (DAH) on five hybrids produced in six environments. Environment effects were significant on both dates for all traits except fructose 30 DAH. Significant hybrid x environment interactions were observed for respiration rate 30 and 120 DAH, for extractable sucrose 120 DAH, and for glucose concentration 30 DAH. The only trait with a significant hybrid main effect was extractable sucrose 30 DAH. For the 90 d between measurements, extractable sucrose losses for individual hybrid-environment combinations ranged from 1 to 63% of the sucrose available 30 DAH. It appeared that large environmental impacts and hybrid x environment interactions, compared to the relatively small hybrid influences, would complicate selecting parental lines with all or most of the storage traits desired. Furthermore, a comprehensive evaluation of commercial hybrids or breeding lines for storage traits would require considerable resources. Efforts to understand the impact of production practices and growing season environment on storage properties would probably be more productive than attempting to produce commercial hybrids with improved storage characteristics.

We developed a landforms model that identifies eleven landform units for Puerto Rico based on parameters of land position and slope. The model is capable of extracting operational information in a simple way and is adaptable to different environments and objectives. The implementation of the landforms model for land cover change analysis represents an advanced step towards understanding the expansion of urban areas and forest cover in Puerto Rico between 1977 and 1994. Expansion of urban areas has typically been associated with low and flat topographies. Forest recovery, on the other hand, has been associated with high elevations and steep slopes. Our study revealed that (1) nearly half of new developments occurred outside the plains, (2) almost all new forests occurred in mountain regions (but not on the steepest slopes), and (3) there are transitional and very dynamic landforms (the side slopes) that experience both important land development and forest recovery. Finally, we present additional examples of the landforms model applications, including vegetation mapping, physiography, and the modeling of vertebrate habitat distributions.

Utilization of toxic substrates was determined by using Biolog MT Microplates inoculated with environmental samples. Water quality variables such as pH, salinity, temperature and turbidity were also measured. In general, temporal changes in the Bay influenced the utilization of these compounds, with increased utilization of toxic compounds during rainy season. Heavy rainfall caused perturbation of sediments rich in organic matter, as was evidenced by increased turbidities. This provided both the environment and the substrates necessary for enhanced microbial growth and activity. The levels of dissolved oxygen in the bay water decreased as a result of increased biological activity. Other environmental factors such as fluctuations in temperature, salinity, and pH appear to have little or no impact on microbial utilization of toxic compounds in the bay water.

PHOSPHORUS LIMITATION; COASTAL ALLUVIAL PLAIN; NUTRIENT ENRICHMENT; RHIZOPHORA-MANGLE; HALOPHYTIC VEGETATION; AVICENNIA-GERMINANS; NORTHERN VENEZUELA; WATER RELATIONS; GAS-EXCHANGE; GROWTH AB We studied gas exchange, leaf dimensions, litter production, leaf and litterfall chemistry, nutrient flux to the forest floor, retranslocation rates, and nutrient use efficiency of mangroves in Jobos Bay, Puerto Rico. The fringe forest had a salinity gradient from the ocean (35 parts per thousand) to a salt flat (100 parts per thousand) and a basin (about 80 parts per thousand). Red (Rhizophora mangle), white (Laguncularia racemosa), and black (Avicennia germinans) mangroves were zoned along this gradient. Photosynthetic rates, stomatal conductance, leaf area and weight, leaf specific area, and nutrient use efficiency decreased with increasing salinity, while xylem tension, nutrient retranslocation, and leaf respiration increased with increasing salinity. The concentration of some leaf elements increased with salinity (N, P, Mg, Na) while others decreased (Ca). Leaf specific area was less variable than leaf area or weight. Maximum photosynthesis (12.7 mu mol CO2 m(-2)s(-1)), leaf conductance (283 mmol CO2 m(-2)s(-1)), and litterfall (16.9 Mg ha(-1) yr(-1)) in the fringe were high in comparison with those of other world mangroves. Nutrient flux to the forest floor was also high and nutrient use efficiency was low in this forest. Part of the reason for these high values and low use-efficiencies was the high proportion of nutrient-rich flowers and propagules in litterfall. Nevertheless, access to freshwater in the form of ground-water discharge and about 1 m of annual rainfall play a role in the high productivity of the Jobos mangroves.

TI Composition of functional lipids in hulled and hulless barley in fractions obtained by scarification and in barley oil SO CEREAL CHEMISTRY LA English DT Article ID QUANTITATIVE-ANALYSIS; TOCOTRIENOLS; CHOLESTEROL; EXTRACTION; ETHANOL; CORN; RYE AB Two cultivars of hulled barley (Thoroughbred and Nomini) and two cultivars of hulless barley (Doyce and Merlin) were scarified to abrade the outer layers of hull and pericarp. The resulting scarification fines fractions were evaluated as potential sources of functional lipids (phytosterols, tocopherols, and tocotrienols). The levels of total phytosterols and total tocotrienols in the barley scarification fine fractions were probably not high enough to justify their use as functional foods. However, the levels of total phytosterols and total tocotrienols in the oils extracted from both whole kernels and scarified fines were both sufficiently high to make it reasonable to consider their potential use as new functional oils. Indeed, the levels of total tocotrienols in barley oils (2,911-6,126 mg/kg of oil) are several-fold higher than those reported in two other oils that are being marketed as high in tocotrienols: palm oil (530 mg/kg) and rice bran oil (770 mg/kg). The levels of total phytosterols in barley oils range from 1.20 to 9.60 g/100 g of oil. C1 USDA ARS, Eastern Reg Res Ctr, Crop Convers Sci & Engn Res Unit, Wyndmoor, PA 19038 USA.

The procedure was optimized for grinding, liquefaction, saccharification, and fermentation parameters. The optimized procedure was reproducible with a coefficient of variation of 3.6% in ethanol yield. Five particle size distributions of ground corn were obtained using a cross-beater mill equipped with five screens (0.5, 2, 3, 4, and 5 mm). Particle size had an effect on ethanol yield and on soluble solids concentration in thin stillage. The highest ethanol yield of 12.6 mL/100 mL of beer was achieved using a 0.5-mm screen in the cross-beater mill. Treatment using the 0.5-mm mill screen resulted in soluble solids concentration of 25.1 g/L and was higher than soluble solids concentrations obtained with other screens. No differences in soluble solid concentrations were observed in samples of thin stillage obtained from 2, 3, 4, and 5-mm screens which had a mean yield of 16.2 g/L. By optimizing particle size for maximum ethanol yield and minimum solids in thin stillage, dry-grind corn plants could realize reduced capital and operating costs.

TI Comparison of raw starch hydrolyzing enzyme with conventional liquefaction and saccharification enzymes in dry-grind corn processing SO CEREAL CHEMISTRY LA English DT Article ID SACCHAROMYCES-CEREVISIAE; GROWTH; FERMENTATION; ENERGY; YEAST AB In a conventional dry-grind corn process, starch is converted into dextrins using liquefaction enzymes at high temperatures (90-120 degrees C) during a liquefaction step. Dextrins are hydrolyzed into sugars using saccharification enzymes during a simultaneous saccharification and fermentation (SSF) step. Recently, a raw starch hydrolyzing enzyme (RSH), Stargen 001, was developed that converts starch into dextrins at low temperatures (< 48 degrees C) and hydrolyzes dextrins into sugars during SSF. In this study, a dry-grind corn process using RSH enzyme was compared with two combinations (DG1 and DG2) of commercial liquefaction and saccharification enzymes. Dry-grind corn processes for all enzyme treatments were performed at the same process conditions except for the liquefaction step. For RSH and DG1 and DG2 treatments, ethanol concentrations at 72 hr of fermentation were 14.1-14.2% (v/v). All three enzyme treatments resulted in comparable ethanol conversion efficiencies, ethanol yields, and DDGS yields. Sugar profiles for the RSH treatment were different from DG1 and DG2 treatments, especially for glucose. During SSF, the highest glucose concentration for RSH treatment was 7% (w/v), whereas for DG1 and DG2 treatments, glucose concentrations had maximum of 19% (w/v). Glycerol concentrations were 0.5% (w/v) for RSH treatment and 0.8% (w/v) for DG1 and DG2 treatments. C1 Univ Illinois, Dept Agr & Biol Engn, Urbana, IL 61801 USA.

Therefore, it is important to accurately measure their concentrations in foods and feeds and to determine how genetics and growing environment can influence their levels. The first objective was to evaluate saponification versus direct extraction for the analysis of tocols in oat (Avena sativa L.). The second was to determine the effects of growing environment, hulled versus hulless phenotype, and genetic background on tocol concentration, and to see whether tocol and lipid concentrations were associated. For the first objective, oat grain samples from two locations were either extracted by saponification or directly with methanol, and extracts were analyzed by HPLC. The saponification method increased yield by approximate to 25% and was less time-consuming, so it was adopted for the second objective. For the second objective, oat genotypes were developed by crossing high-oil parents from Iowa State University with hulled and hulless cultivars adapted to arid Western environments. These were grown at Aberdeen and Tetonia, ID, and the tocols and lipid concentrations were analyzed at Madison, WI. There were significant effects of growing environment, genotype, and the presence or absence of hulls on tocol concentrations. Tocol and lipid concentrations were not correlated. Progeny of crosses involving the genotype IA91098-2 had tocol concentrations that exceeded both parents. C1 USDA ARS, Cereal Crops Res Unit, Madison, WI 53726 USA.

Sorghum bran from a decortication process (10%) was used for this study. The approximate chemical composition of sorghum bran was 30% starch, 18% hemicellulose, 11% cellulose, 11% protein, 10% crude fat, and 3% ash. The objective of this research was to evaluate the effectiveness of selected pretreatment methods such as hot water, starch degradation, dilute acid hydrolysis, and combination of those methods on enzymatic hydrolysis of sorghum bran. Methods for pretreatment and enzymatic hydrolysis of sorghum bran involved hot water treatment (10% solid, w/v) at 130 degrees C for 20 min, acid hydrolysis (H2SO4), starch degradation, and enzymatic hydrolysis (60 hr, 50 degrees C, 0.9%, v/v) with commercial cellulase and hemicellulose enzymes. Total sugar yield by using enzymatic hydrolysis alone was 9%, obtained from 60 hr of enzyme hydrolysis. Hot water treatment facilitated and increased access of the enzymes to hemicellulose and cellulose, improving total sugar yield up to 34%. Using a combination of starch degradation, optimum hot water treatment, and optimum enzymatic hydrolysis resulted in maximum total sugar yield of up to 75%.

The excitation source is a 327-nm light emitting diode (LED) operated in pulsed mode; and the luminescence signal is detected by a photomultiplier tube (PMT). In comparison to a conventional xenon flashlamp, an LED is small, light, robust, and energy efficient. More importantly, its narrow emission bandwidth and low residual radiation reduce background signal. In pulse mode, an LED operates at a current 1-2 orders of magnitude lower than that of a xenon flashlamp, thus minimizing electromagnetic interference (EMI) to the detector circuitry. The PMT is gated to minimize its response to the light source. These measures lead to reduced background noise in time domain. To overcome pulse-to-pulse variation signal normalization is implemented based on individual pulse energy. Instrument operation and data processing are controlled by a computer running a custom LabVIEW program. Enrofloxacin (ENRO) is used as a model analyte to evaluate instrument performance. The integrated TSL intensity reveals a linear dependence up to 2 ppm. A 1.1-ppb limit of detection (LOD) is achieved with relative standard deviation (RSD) averaged at 5.1%. The background noise corresponds to similar to 5 ppb. At 19 lbs, this portable analyzer is field deployable for agriculture, environmental and clinical analyses.

TI Adsorption behavior of epoxidized fatty esters via boundary lubrication coefficient of friction measurements SO CHEMICAL ENGINEERING COMMUNICATIONS LA English DT Article DE adsorption; epoxide; ester; soybean oil ID SUPERCRITICAL CARBON-DIOXIDE; SOYBEAN OIL; METHYL-ESTERS; LONG-CHAIN; HEAT AB The frictional behaviors of a variety of fatty alkenyl esters and their corresponding fatty epoxide esters (epoxy methyl oleate (EMO) and methyl oleate (MO), epoxy methyl linoleate (EMLO) and methyl linoleate (MLO), epoxy methyl linolenate (EMLEN) and methyl linolenate (MLEN)), epoxidized soybean oil (ESBO), and a commercial epoxidized 2-ethylhexyl transesterified soybean oil (VF) as additives in hexadecane have been examined in a boundary lubrication test regime using steel contacts. Langmuir critical additive concentrations were determined, which provide the following order of negative adsorption energies: ESBO > VF > EMO >= EMLO > EMLEN and MLEN >= MLO > MO. Thus, for the similar epoxidized materials the greater degree of epoxidation results in less negative calculated total adsorption energies; this trend is reversed for the olefinic parent systems. This ordering agrees with that obtained via a more complex unconstrained cooperative interaction adsorption model. Fits of the steady-state coefficient of friction (COF) versus concentration data indicate an inverse relation of the obtained interaction parameters (a) with the primary adsorption energies (E). These results demonstrate the complexity of the adsorption mechanism that occurs. C1 ARS, Food & Ind Oils Res Unit, Natl Ctr Agr Utilizat Res, USDA, Peoria, IL 61604 USA.

SYRINGAE B301D; ADENYLATION DOMAINS; NATURAL-PRODUCTS; AMINO-ACIDS; COTTON SEEDLINGS; BIOSURFACTANTS; IDENTIFICATION AB With the increasing number of genomes sequenced and available in the public domain, a large number of orphan gene clusters, for which the encoded natural product is unknown, have been identified. These orphan gene clusters represent a tremendous source of novel and possibly bioactive compounds. Here, we describe a "genomisotopic approach," which employs a combination of genomic sequence analysis and isotope-guided fractionation to identify unknown compounds synthesized from orphan gene clusters containing nonribosomal peptide synthetases. Analysis of the Pseudomonas fluorescens Pf-5 genome led to the identification of an orphan gene cluster predicted to code for the biosynthesis of a lipopeptide natural product. Application of the genomisotopic approach to isolate the product of this gene cluster resulted in the discovery of orfamide A, founder of a group of bioactive cyclic lipopeptides.

The extracts were from the primary host, ponderosa pine, Pinus ponderosa Dougl. ex Laws. (Pinaceae); two nonhost angiosperms, California black oak, Quercus kelloggii Newb. (Fagaceae), and quaking aspen, Populus tremuloides Michx. (Salicaceae); and seven nonhost conifers, white fir, Abies concolor (Gord. & Glend.) Lindl. ex Hildebr. (Pinaceae), incense cedar, Calocedrus decurrens (Torr.) Florin (Cupressaceae), Sierra lodgepole pine, P. contorta murrayana Grev. & Balf. (Pinaceae), Jeffrey pine, P. jeffreyi Grev. & Balf. (Pinaceae), sugar pine, P. lambertiana Dougl. (Pinaceae), Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco (Pinaceae), and mountain hemlock, Tsuga mertensiana (Bong.) Carr. (Pinaceae). Sixty-four compounds were identified from the ten trees, 42 of which elicited antennal responses in D. brevicomis, usually in both sexes. In addition, several synthetic compounds, including a number of the antennally-active compounds from the extracted trees and some bark beetle pheromone components, elicited antennal responses in a manner similar to that observed with the extracts. Of the antennally-active compounds known to be present in trees sympatric with D. brevicomis, only geraniol was unique to its host. Four antennally-active compounds were, found in the host and in other conifers; five compounds were found only in nonhost conifers; eight compounds were found in either or both of the nonhost angiosperms; eight compounds were found in either or both of the angiosperms and in nonhost conifers, but not in the host; and 19 were found in both the host and in angiosperms and/or nonhost conifers. Several bark beetle pheromone components were found in the stem volatile extracts. Conophthorin was identified from both nonhost angiosperms; exo-brevicomin was identified in A. concolor; verbenone was identified from a number of nonhost conifers; and chalcogran was identified from R tremuloides. The number of nonhost volatile chemicals that D. brevicomis encounters and is capable of detecting, and the diversity of sources from which they emanate, highlight the complexity of the olfactory environment in which D. brevicomis forages. This provides a basis for further work related to chemically-mediated aspects of foraging in this insect and perhaps other coniferophagous bark beetles, and highlights the need to consider foraging context in the design and implementation of semiochemical-based management tactics for tree protection.

Two PBDE congeners that are particularly prominent in environmental samples are 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) and 2,2,4,4',5-pentabromodiphenyl ether (BDE-99). These two congeners are major components in penta-BDE formulations which constitute a minor percentage of the commercial PBDE market. In order to determine the bioavailability and bioconcentration potential of these PBDEs, we have conducted a feeding experiment in rats, dosing with low amounts of a commercial penta-BDE mixture for 21 days to mimic an environmental exposure. The carcasses, livers, and feces from control and dosed rats were quantitated for PBDEs by a high resolution GC-MS isotope dilution method. Between 25% and 50% of each of the dosed congeners was retained in the rats with the liver being a minor depot (< 1% of the dose). Fecal excretion accounted for 4-12% of the dosed congeners. A large percent of the dose (40-60%) was not recovered indicating that metabolic transformations may have occurred in the rats. Hydroxylated metabolites were qualitatively identified in the feces and carcass by GC-MS. The relative congener distribution in each tissue was nearly identical to the congener distribution of the commercial mixture. Conclusions from the study suggest that the tetra- to hexa-BDEs present in commercial penta-BDE formulations are largely bioavailable, that bioavailability in the rat is not dependent on the degree of bromination, and that metabolism may occur to a large extent during a chronic exposure.

Lutein and zeaxanthin have been implicated in the protection of age related macular degeneration (AMD) and in cardiovascular diseases. However, xanthophylls and unidentified components (lambda(max) = 423 and 468 nm) in plant products are often not separated well, and affect an accurate quantitative determination of lutein and zeaxanthin. A high performance liquid chromatography (HPLC) system equipped with a Bischoff C30 column and a mobile phase of methanol, metkyl-tert-butyl ether (MTBE) and water was used to separate lutein, zeaxanthin and other unidentified components in plant products. Mobile phase A containing methanol, MTBE and water with a ratio of 60:33:7 by volume (1.5% ammonium acetate, NH4Ac), combined with mobile phase B with a ratio of 8:90:2 by volume (1.0% NH4Ac) is optimal for the separation. This method was successfully applied to the quantitative determination of lutein and zeaxanthin in extracts of plant products, such as chlorella, spirulina, celery and mallow.

This presentation describes (1) C sequestration concepts and rationale, (2) relevant management approaches to avoid land degradation and foster C sequestration, and (3) a summary of research quantifying soil C sequestration. The three primary greenhouse gases (CO2,CH4, and N2O) derived from agriculture have increased dramatically during the past century. Conservation management practices can be employed to sequester C in soil, counter land degradation, and contribute to economic livelihoods on farms. Trees can accumulate C in perennial biomass of above-ground and below-ground growth, as well as in the deposition of soil organic matter. Minimal disturbance of the soil surface with conservation tillage is critical in avoiding soil organic C loss from erosion and microbial decomposition. Animal manures contain 40-60% C, and therefore, application to land promotes soil organic C sequestration and provides readily-available, recycled nutrients to crops. Green manures can be used to build soil fertility, often with leguminous plant species having symbiotic root associations with nitrogen-fixing bacteria. Grasslands have great potential to sequester soil organic C when managed properly, but can also be degraded due to overgrazing, careless management, and drought leading to accelerated soil erosion and undesirable species composition. Opportunities exist to capture and retain greater quantity of C from crop and grazing systems when the two systems are integrated. Fertilization is needed to achieve production goals, but when applied excessively it can lead to environmental pollution, especially when considering the energy and C cost of manufacture and transport. Agricultural conservation management strategies to sequester CO, from the atmosphere into soil organic matter will also likely restore degraded land and/or avoid further land degradation.

TI Long-term modeling of soil C erosion and sequestration at the small watershed scale SO CLIMATIC CHANGE LA English DT Article ID ORGANIC-CARBON SEQUESTRATION; GREENHOUSE-GAS EMISSIONS; MANAGEMENT-PRACTICES; SOUTHERN ALBERTA; MATTER DYNAMICS; CROP-ROTATION; EPIC MODEL; YIELD; WHEAT; DEPOSITION AB The soil C balance is determined by the difference between inputs (e.g., plant litter, organic amendments, depositional C) and outputs (e.g., soil respiration, dissolved organic C leaching, and eroded C). There is a need to improve our understanding of whether soil erosion is a sink or a source of atmospheric CO(2). The objective of this paper is to discover the long-term influence of soil erosion on the C cycle of managed watersheds near Coshocton, OH. We hypothesize that the amount of eroded C that is deposited in or out of a watershed compares in magnitude to the soil C changes induced via microbial respiration. We applied the erosion productivity impact calculator (EPIC) model to evaluate the role of erosion-deposition processes on the C balance of three small watersheds (similar to 1 ha). Experimental records from the USDA North Appalachian Experimental Watershed facility north of Coshocton, OH were used in the study. Soils are predominantly silt loam and have developed from loess-like deposits over residual bedrock. Management practices in the three watersheds have changed over time. Currently, watershed 118 (W118) is under a corn (Zea mays L.)-soybean (Glycine max [L.] Merr.) no till rotation, W128 is under conventional till continuous corn, and W188 is under no till continuous corn. Simulations of a comprehensive set of ecosystem processes including plant growth, runoff, and water erosion were used to quantify sediment C yields. A simulated sediment C yield of 43 +/- 22 kg C ha(-1) year(-1) compared favorably against the observed 31 +/- 12 kg C ha(-1) year(-1) in W118. EPIC overestimated the soil C stock in the top 30-cm soil depth in W118 by 21% of the measured value (36.8 Mg C ha(-1)). Simulations of soil C stocks in the other two watersheds (42.3 Mg C ha(-1) in W128 and 50.4 Mg C ha(-1) in W188) were off by < 1 Mg C ha(-1). Simulated eroded C re-deposited inside (30-212 kg C ha(-1)year(-1)) or outside (73-179 kg C ha(-1) year(-1)) watershed boundaries compared in magnitude to a simulated soil C sequestration rate of 225 kg C ha(-1) year(-1) and to literature values. An analysis of net ecosystem carbon balance revealed that the watershed currently under a plow till system (W128) was a source of C to the atmosphere while the watersheds currently under a no till system (W118 and W188) behaved as C sinks of atmospheric CO(2). Our results demonstrate a clear need for documenting and modeling the proportion of eroded soil C that is transported outside watershed boundaries and the proportion that evolves as CO(2) to the atmosphere.

We describe here an approach that utilizes translationally active PCR fragments for the rapid in vitro transcription and translation of recombinant proteins for antigen discovery in M. avium subsp. paratuberculosis. The investigations showed that the MAP1272c protein selectively reacts with sera from Johne's disease-positive cattle and represents an antigen of potential utility in M. avium subsp. paratuberculosis immunodiagnostics.

TI Pterostilbene, an active constituent of blueberries, suppresses aberrant crypt foci formation in the azoxymethane-induced colon carcinogenesis model in rats SO CLINICAL CANCER RESEARCH LA English DT Article ID NITRIC-OXIDE SYNTHASE; CYCLOOXYGENASE-2 INHIBITOR; CHEMOPREVENTIVE PROPERTIES; RED WINE; RESVERATROL; CANCER; EXPRESSION; AGENTS; PHYTOALEXIN; PREVENTION AB Purpose: Epidemiologic studies have linked the consumption of fruits and vegetables to reduced risk of several types of cancer. Laboratory animal model studies have provided evidence that stilbenes, phenolic compounds present in grapes and blueberries, play a role in inhibiting the risk of certain cancers. Pterostilbene, a naturally occurring stilbene from blueberries, was tested for its preventive activity against colon carcinogenesis. Experimental Design: Experiments were designed to study the inhibitory effect of pterostilbene against the formation of azoxymethane-induced colonic aberrant crypt foci (ACF) preneo-plastic lesions in male F344 rats. Beginning at 7 weeks of age, rats were treated with azoxymethane (15 mg/kg body weight s.c., once weekly for 2 weeks). One day after the second azoxymethane treatment, rats were fed experimental diets containing 0 or 40 ppm of pterostilbene. At 8 weeks after the second azoxymethane treatment, all rats were sacrificed, and colons were evaluated for ACF formation and for inhibition of inducible nitric oxide synthase (iNOS) and proliferating cell nuclear antigen. Effects on mucin MUC2 were also determined. Results: Administration of pterostilbene for 8 weeks significantly suppressed azoxymethane-induced formation of ACF (57% inhibition, P < 0.001) and multiple clusters of aberrant crypts (29% inhibition, P < 0.01). Importantly, dietary pterostilbene also suppressed azoxymethane-induced colonic cell proliferation and iNOS expression. Inhibition of iNOS expression by pterostilbene was confirmed in cultured human colon cancer cells. Conclusions: The results of the present study suggest that pterostilbene, a compound present in blueberries, is of great interest for the prevention of colon cancer.

By determining which structural characteristics of such weak layers are associated with shear strength, we may be better able to monitor and predict stability, which is relevant for avalanche forecasting and management. We utilize moving window statistical operations to analyze SnowMicroPen (SMP) penetrometer hardness profiles of a buried surface hoar layer. Results indicate that significant weak layer thinning and hardening of the interface between the weak layer and its substratum coincided with significant increases in shear strength, as measured using a size-corrected shear strength index derived from concurrent stability tests. With aging, variations in slab thickness appeared to positively affect the hardness and inversely affect the coefficient of variation (CoV) of hardness of weak layer boundaries. These findings support previous research that proposed the strengthening of buried surface hoar layers results from the gradual penetration of the surface hoar crystals into the substratum which allows stronger bonds to form at this critical interface. These analytical techniques allow stratigraphic dimensions and hardness characteristics to be quantified and analyzed, improving our ability to monitor stratigraphic characteristics associated with shear strength and stability of the mountain snowpack.

Greater variability increases uncertainty in extrapolation and prediction. Our results offer a look at the evolution of the spatial variability of shear strength of two buried surface hoar layers in southwestern Montana, USA, over time. We studied the layers from shortly after burial until they were no longer the weakest layer in the snowpack. We selected study sites with planar slopes, uniform ground cover, and wind-sheltered locations. This simplified the comparison of the plots by minimizing initial spatial differences so we could focus on temporal change. Within each site, we sampled four 14 m x 14 m plots with more than 70 shear frame tests in a layout optimized for spatial analysis. At both sites, the layers gained strength at a rate that slowed as the layers aged. Although there was little change in the relative variability, absolute variability increased through time. Temporal change was more pronounced when the layers were younger and were gaining strength more rapidly. Additional tests at one plot suggested a correlation length, or the distance at which test results are related, for shear strength of just a few meters. At the other plot, the surface hoar layer collapsed during the initial sample. An initial dramatic decrease in shear strength occurred after this collapse followed by strengthening during that day and into the following day. Though we measured increasing absolute variability through time, uncovering changes in our other measures of spatial variability proved elusive. Developing methods and techniques for adequately characterizing variability, and temporal changes in that variability, will continue to be challenging. (c) 2006 Elsevier B.V. All rights reserved.

TI Effects of moisture on ignition behavior of moist California chaparral and Utah leaves SO COMBUSTION SCIENCE AND TECHNOLOGY LA English DT Article DE ignition; live fuels; wildland fire ID FIRE SPREAD; MODEL AB Individual cuttings from eight plant species native to California chaparral or Utah were burned in a well-controlled, well-instrumented facility. Gas temperatures above a flat-flame burner were controlled at 987 +/- 12 degrees C and 10 +/- 0.5 mol% O-2, resulting in a heat flux at the leaf surface varying from 80-140 kW/m(2). High moisture leaves were observed to burst due to the rapid escape of vapor from the leaf interior. Bubbles in or on the leaf surface were observed for leaves with moderate moisture contents. A large number of leaf temperature measurements were made, along with measurements of the ignition time and temperature, flame height, and flame duration. Average ignition temperatures were species dependent, ranging from 227 degrees C to 453 degrees C, with a large degree of scatter from leaf to leaf. Correlations of time to ignition and ignition temperature were made, but showed only a weak dependence on leaf thickness and almost no dependence on mass of moisture in the leaf. Leaf samples with similar mass showed that Utah juniper took longer to burn than the other species, and that the Utah broadleaf species burned more rapidly than all the other species.

Effects of different rates of preplant N (PP-N) applications and different rates and frequencies of in-season N (IS-N) for two potato cultivars were evaluated for 2 years (2001 and 2002) in a Quincy fine sand (mixed, mesic, Xeric Torripsamments) in the Pacific Northwest (PNW). in the 2001 experiment, the petiole nitrate (NO3-N) concentrations in both the cultivars were in the optimum range in the samples taken 22 days after emergence (DAE). In the subsequent sampling, the petiole NO3-N concentrations showed a wide range proportional to the rates of IS-N. In the 2002 experiment, the petiole NO3-N concentrations were in the excess range in most treatments until about 51 DAE in both the cultivars, followed by a decline in concentrations to the low range. The petiole phosphorus (P) and potassium (K) concentrations were mostly above the excess range in both the cultivars over the entire sampling period. The soil N data showed that the transformation of urea N was quite rapid and that the extractable ammonium (NH4-N) and NO3-N concentrations in the soil returned to the background levels within 90 days after the PP-N application. The results of this study demonstrate a rapid transformation of preplant applied urea N into NH4-N and NO3-N and depletion of the available N in the top 120 cm of soil. This, in turn, supports the need for IS-N applications to meet the crop N requirement during the later growing period. C1 USDA ARS, Prosser, WA 99350 USA.

The kinetics of P sorption by an Ultisols from West Virginia, USA, receiving P from fertilizers were compared to soils amended with turkey litter. Addition of 6.6 and 13.2 Mg turkey litter ha(-1) increased Bray 1P levels to about the same level as adding 53 and 115 kg P ha(-1), respectively. Phosphorus binding capacity decreased to a greater extent when P was added as fertilizer as compared to turkey litter. For example, P binding maximum was 360 mg P kg(-1) dry soil when soil was amended with 6.6 Mg turkey litter ha(-1) as compared to 260 mg P kg(-1) dry soil when amended with 53 kg P ha(-1). This study demonstrates that the decrease in P-binding capacity with increasing soil P is less when P is added as turkey litter.

TI Short-term effect of lime, phosphorus, and iron amendments on water-extractable lead and arsenic in orchard soils SO COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS LA English DT Article DE lead arsenate; soil amendments lime; water-extractable As; water-extractable-Pb; phosphorus; and iron oxyhydroxide ID PHOSPHATE; ENVIRONMENT; MOBILITY; BIOAVAILABILITY; PHYTOTOXICITY AB Lead arsenate was extensively used to control insects in apple and plum orchards in the 1900s. Continuous use of lead arsenate resulted in elevated soil levels of lead (Pb) and arsenic (As). There are concerns that As and Pb will become solubilized upon a change in land use. In situ chemical stabilization practices, such as the use of phosphate-phosphorus (P), have been investigated as a possible method for reducing the solubility, mobility, and potential toxicity of Pb and As in these soils. The objective of this study was to determine the effectiveness of calcium carbonate (lime), P, and iron (Fe) amendments in reducing the solubility of As and Pb in lead-arsenate-treated soils over time. Under controlled conditions, two orchard soils, Thurmont loam (Hapludults) and Burch loam (Haploxerolls), were amended with reagent- grade calcium carbonate (CaCO3), iron hydroxide [Fe(OH)(3)], and potassium phosphate (KH2PO4) and incubated for 16 weeks at 26 degrees C. The experimental results suggested that the inorganic P increased competitive sorption between H2PO4- and dihydrogen arsenate (H2AsO4-), resulting in greater desorption of As in both Thurmont and Burch soils. Therefore, addition of lime, potassium phosphate, and Fe to lead-arsenate-contaminated soils could increase the risk of loss of soluble As and Pb from surface soil and potentially increase these metal species in runoff and movement to groundwater.

The objectives of this research were to evaluate manure P extraction and sample storage procedures and to characterize manure types for water-extractable P (WEP) and NaHCO3 P (BiEP). Manure P was extracted at dry matter-to-water extraction ratios of 0.5g/200mL, 2 g/200 mL, 2g/20 mL, and 20 g/200 mL. Shaking times of 0.5 h, 1 h, or 2 h were evaluated along with filter paper types ( Whatman No. 42, Whatman No. 40, and 0.45-mu m). Single or sequential extractions and repeated extractions with water or NaHCO3 were also compared on various manure sources. Manure types were treated as replications in the analysis of variance to reduce the probability of making a Type I error in applying the results to diverse manure types. Dry matter-to-water extraction ratios more concentrated than 1g/100 mL removed less P than extraction at 1g/200 mL, which removed a similar percentage of total P (TP) as 0.5 g/200 mL ratio. A single extraction with a 1g/200 mL or more dilute ratio with 1 h of shaking time was found to give a good estimate of extractible P. Extracted manure P was similar for three sequential extractions of 1g/100 mL dilution ratio compared to one extraction with 1g/300 mL. Filter paper type did not affect the amount of P extracted. Phosphorus extraction was more consistent with samples stored dry as compared to refrigerated or frozen conditions. Extractible P in swine manure, as a percentage of TP, was more than for other manure types. C1 Univ Nebraska, Dept Agron & Hort, Lincoln, NE 68583 USA. USDA, NRCS, Lincoln, NE USA.

TI Utilization of existing technology to evaluate spring wheat growth and nitrogen nutrition in South Dakota SO COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS LA English DT Article DE near infrared; nitrogen; precision agriculture; spring wheat ID CORN CANOPIES; WINTER-WHEAT; REFLECTANCE; YIELD; SOIL AB Sensor-based technologies for in-season application of nitrogen (N) to winter wheat (Triticum aestivum L.) have been developed and are in use in the southern Great Plains. Questions arise about the suitability of this technology for spring wheat production in the northern Great Plains. A field experiment was established in Brookings, SD, to evaluate the GreenSeeker Hand Held optical sensor (NTech Industries, Ukiah, CA) for predicting in-season N status on three spring wheat cultivars (Ingot, Oxen, and Walworth) across five N treatments. Nitrogen rates were 0, 34, 68, 102, and 136 kg N ha(-1) applied preplant as ammonium nitrate. Sensor readings and plant biomass samples were collected at Feekes 6 and Feekes 10 growth stages. The sensor measures reflectance in the red and near infrared (NIR) regions of the electromagnetic spectrum. A normalized difference vegetation index (NDVI) was calculated. The ability of the sensor readings to predict biomass, plant N concentration, and plant N uptake for each sampling date was determined. In general, biomass, plant N concentration, and N uptake increased with increasing N rate for both sampling dates. Readings collected at Feekes 6 and Feekes 10 showed a significant relationship with plant biomass, N concentration, and N uptake for all varieties. Plant N uptake and NDVI resulted in a higher regression coefficients compared to biomass and plant N concentration for all varieties. Results suggest that existing sensor-based variable nitrogen technology developed for winter wheat could be utilized in the northern Great Plains for estimating in-season N need for spring wheat.

Thirty- six field lysimeters with six different ground covers [ bare ground, orchardgrass ( Dactylis glomerata L.), tall fescue ( Festuca arundinacea Schreb.), smooth bromegrass ( Bromus inermis Leyss.), timothy ( Phleum pratense L.), and switchgrass ( Panicum virgatum L.)] were established to evaluate the ability of grasses to reduce nutrient levels in soils and shallow groundwater. Nitrate ( NO3-) and orthophosphate ( PO43-) were uniformly applied to each lysimeter. In addition, half of the lysimeters received an application of atrazine, and the other half received isoxaflutole ( Balance (TM)) at levels indicative of surface runoff from cropland. The leachate from each lysimeter was collected after major rainfall events during a 25- day period, and soil was collected from each lysimeter at the end of the 25- day period. Water samples were analyzed for NO3- N and PO4- P, and soil samples were analyzed for NO3- N. Grass treatments reduced NO3- N levels in leachate by 74.5 to 99.7% compared to the bare ground control, but timothy was significantly less effective at reducing NO3- N leaching than the other grasses. Grass treatments reduced residual soil NO3- N levels by 40.9 to 91.2% compared to the control, with tall fescue, smooth bromegrass, and switchgrass having the lowest residual levels. Switchgrass decreased PO4-P leaching to the greatest extent, reducing it by 60.0 to 74.2% compared to the control. The ability of the forage grasses to reduce nutrient levels in soil or shallow groundwater were not significant between herbicide treatments. Quantification of microbial NO3- dissipation rates in soil suggested that denitrification was greatest in switchgrass, smooth bromegrass, and tall fescue treatments. The overall performance of these three grasses indicated that they are the most suitable for use in vegetative buffers because of their superior ability to dissipate soil NO3- and reduce nutrient transport to shallow groundwater.

The objective of this study was to determine optimum ICP- OES operational parameters for aluminum ( Al), copper ( Cu), iron ( Fe), manganese ( Mn), sodium ( Na), phosphorus ( P), and zinc ( Zn) in natural water samples. Five radio- frequency forward powers ( RF powers) and four nebulizer gas flow rates were tested. Different RF power values and nebulizer gas flow rates were found to be ideal for each element. Performance was best for Al, Na, and P at 1400 W RF power, whereas the optimal nebulizer gas flow rate for Na, Fe, Zn, and Al was 1 L min(-1). The differences in RF power and nebulizer gas flow rates were found to be driven by changes in 1) element emission lines for different RF powers and 2) evaporation rates, mean diameter drop sizes, solvent loading, and analyte signal intensities for different nebulizer gas flow rates and analyte concentrations. Grouping the elements with similar parameters will avoid reading delays. C1 USDA ARS, Natl Soil Eros Res Lab, W Lafayette, IN 47907 USA. Purdue Univ, W Lafayette, IN 47907 USA.

Results indicated that the ammonia volatilization rate at 20% FC soil water regime was two- to three- fold greater than that at 80% FC. The cumulative volatilization loss over 28 days was up to 25.7%. Results of this study demonstrated that ammonia volatilization was accelerated at low soil water regimes.

The effects of acidified extractions on soluble P ( SP) concentrations were studied, and a buffer was selected to measure SP at pH 6.0, which is a target value for soil management in Georgia. Soluble P concentrations were extracted from poultry wastes at three pHs: 1) at natural pH, using deionized water ( DIw); 2) after titrating DIw suspensions with 0.5N hydrochloric acid ( HCl) to pH end- points 3.0, 4.0, and 6.0; and 3) at pH 6.0 with buffers of sodium ( Na) acetate, potassium hydrogen phthalate ( KHP), 2-( Nmorpholino) ethanesulphonic acid ( MES), Na cacodylate, imidazole, N-( 2- acetamido)- 2- aminoethansulphonic acid ( ACES), N-( carbamoyl- methyl) iminodiacetic acid ( ADA), bis-( 2- hydroxyethyl) imino]- tris-[( hydroxymethyl) methane ( Bistris), and 1,4 piperazine- bis-( ethane sulphonic acid) ( PIPES). Total SP increased 60% to 140% in suspensions acidified with HCl to pH 6.0 compared to suspensions at pH >= 8. Dissolved unreactive P responded more ( 2x to 30x) than molybdate reactive P( 20 - 100%). Buffers extracted more soluble minerals than suspensions acidified with HCl, probably because of their complexation ability. The most effective buffer was MES, because its effects seemed mainly due to acidification. C1 Univ Georgia, Agr & Environm Serv Labs, Athens, GA 30602 USA.

Gross transformations of manure N, including mineralization ( m), immobilization ( i), and nitrification ( n), can be quantified using 15 N pool dilution methods. This research measures gross m, n, and i resulting from application of four freeze- dried dairy manures that had distinctly different patterns of N availability. A sandy loam soil ( coarse- loamy, mixed, frigid Typic Haplorthod) was amended with four different freeze- dried dairy manures and incubated at 25 degrees C with optimal soil water content. The dilution of 15 ammonium ( NH4(+)) during a 48- h interval ( 7 - 9 d and 56 - 58 d after manure application) was used to estimate m, whereas the dilution of 15 nitrate ( NO3-) was used to estimate n. Gross immobilization was calculated as gross minus net mineralization. Gross mineralization in the unamended soil was similar at 7- to 9- d and 56- to 58- d intervals and was significantly increased by the application of manures. For both amended and unamended soil, m was much greater ( i. e., three- to nine- fold) than estimated net mineralization, illustrating the degree to which manure N can be cycled in soil. At the early interval, both m and i were directly related to the manure C input, demonstrating the linkage between substrate C availability and N utilization by soil microbes. This research clearly shows that the application of dairy manures stimulates gross N transformation rates in the soil, improving our understanding of the impact of manure application on soil N cycling.

We evaluated the multiyear use of biosolids in apricot ( Prunus armeniaca L.) production, grown on productive agricultural soils. Class A biosolids were initially applied annually at rates of 0, 1.9, 5.8, and 11.7 Mg. ha(-1) ( dry basis) to a 2-year- old apricot orchard on the USDAARS research site on the eastern side of the San Joaquin Valley, CA. These application rates provided estimated rates of 0 ( control), 57, 170, and 340 kg total N. ha(-1) yr(-1), respectively. Compared to the control treatment, the applications of biosolids significantly increased soil salinity ( electrical conductivity from 1: 1 soil - water extract) and total concentrations of nutrients [ e. g., calcium ( Ca), magnesium ( Mg), sulfur ( S), phosphorus ( P), zinc ( Zn), and copper ( Cu)] after 7 years but did not increase the concentrations of selected metals [ cadmium ( Cd), chromium ( Cr), cobalt ( Co), nickel ( Ni), and lead ( Pb)] between 0- and 60- cm soil depths. Mean concentrations of total nitrogen ( N) and carbon ( C) in soils ( 0- to 15- cm depth) ranged from a low of 1.3 g kg(-1) to a high of 5.2 g. kg(-1) and from 14.1 g. kg(-1) to 45.7 g. kg(-1) for the control and high biosolids treated soils, respectively.

In recent years, because of intensive cropping on these soils, deficiency of micronutrients is increasing. A field experiment was conducted on an Oxisol during three consecutive years to assess the response of common bean ( Phaseolus vulgaris L.) under a no- tillage system to varying rates of lime ( 0, 12, and 24 Mg ha(-1)) and boron ( 0, 2, 4, 8, 12, 16, and 24 kg ha(-1)) application. Both time and boron ( B) were applied as broadcast and incorporated into the soil at the beginning of the study. Changes in selected soil chemical properties in the soil profile ( 0- to 10- and 10- to 20- cm depths) with liming were also determined. During all three years, gain yields increased significantly with the application of lime. However, B application significantly increased common bean yield in only the first crop.

It was previously reported that glyphosate accumulation in the rhizosphere may stimulate colonization of soybean [Glycine max (L.) Merr.] roots by soilborne Fusarium. Field studies often reveal inconsistent root colonization by Fusarium, especially during growing seasons characterized by contrasting rainfall patterns. Therefore, this study was lid 0 conducted to determine the impact of different soil moisture contents on root colonization of glyphosate-treated soybean by Fusarium species. Glyphosate (0.84 kg ae ha(-1)) was applied to greenhouse-grown glyphosate-resistant (GR) soybean at the two to three trifoliate-leaf (V2-V3) growth stage growing in a Mexico silt loam at 27%, 13%, and 10% soil moisture contents. Soil and plant samples were sampled periodically after herbicide application and selectively cultured for Fusarium. Highest Fusarium colonization was associated with the glyphosate treatment, with maximum levels occurring at the highest soil moisture level. Thus, glyphosate interactions with root colonization by Fusarium in glyphosate-resistant soybean are greatly influenced by soil moisture content.

TI Comparison of laboratory methods and an in situ method for estimating nitrogen mineralization in an irrigated silt-loam soil SO COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS LA English DT Article DE corn; nitrogen; Zea mays L ID ELECTRICAL-CONDUCTIVITY; AVAILABILITY; MANURE AB Nitrogen (N) mineralization makes a considerable contribution to crop-available N and is difficult to estimate. Reliable methods for measuring N mineralization are needed to produce data sets for developing N-mineralization models, as a component in fertilizer recommendation algorithms, and to assess the effect of management practices on N mineralization. Numerous methods are available for estimating N mineralization. Laboratory methods are relatively easy but may not reflect conditions in the field, and field methods are usually labor-intensive. A study was conducted to compare N-mineralization estimates using anaerobic and aerobic laboratory methods and an in situ field method for the 0- to 15-cm depth of a silt loam soil under irrigated corn (Zea mays L.). Mineralization estimates were also compared to N mineralization based on crop N content. Estimates of N mineralization were 101 kg ha(-1) for the anaerobic laboratory method, 284 kg ha(-1) for the aerobic laboratory method, and 134 kg ha(-1) for the in situ field method. The in situ field method provided a reasonable estimate of N mineralization (0 to 15 cm) when compared to the estimate of mineralized N (root zone) based on crop N content (215 kg ha(-1)). The in situ field method can be used to measure N mineralization during the growing season and for comparing N mineralization among management practices.

Atrazine, deethylatrazine (DEA), and deisopropylatrazine (DIA) were extracted with methanol (CH(3)OH) followed by liquid-liquid extraction and partitioning into chloroform, with additional cleanup by C(18) solid-phase extraction (SPE). Through the optimization of ionization conditions and ion storage voltages, the background noise of product ion spectra (MS/MS) was reduced dramatically, providing sub-mu g/kg detection limits. Mean recoveries of ATR, DEA, and DIA were 94.3, 105.6, and 113.1%, respectively. The estimated limit of detection (LOD) was 0.6 mu g/kg for ATR, 1.3 mu g/kg for DEA, and 0.3 mu g/kg for DIA. These LODs were one to two orders of magnitude lower than those reported for other GC-MS, GC-MS/MS, high pressure liquid chromatography (HPLC)-UV, or HPLC-MS/MS procedures designed for food-safety monitoring purposes. To validate the developed method, a field experiment was carried out utilizing three replications of four forage treatments (orchardgrass, tall fescue, smooth bromegrass, and switchgrass). Forage plants were sampled for analyses 25 days after atrazine application. DEA concentrations in C3 grasses ranged from 47 to 96 mu g/kg, about 10-fold higher than in switchgrass, a C4 species. The ATR and DIA concentrations were similar, ranging from 1.5 to 13.2 mu g/kg. The developed method provided sufficient sensitivity to determine the fate of ATR and its chlorinated metabolites via plant uptake from soil or dealkylation within living forage grasses. It also represented significant improvements in sensitivity compared to previous GC methods. C1 Univ Missouri, Sch Nat Resources, Ctr Agroforestry, Columbia, MO 65211 USA.

The effects of freeze, air (22 degrees C), and oven (65 degrees C) drying on sequentially fractioned poultry manure P were examined. Higher drying temperatures resulted in lower percentage of dry matter. Increased H2O- and decreased sodium bicarbonate (NaHCO3)-extractable P with drying provided evidence that drying increases poultry manure P solubility. Labile fractions were predominantly inorganic P (P-i), whereas sodium hydroxide (NaOH) and hydrochloric acid (HCl) fractions had significant amounts of organic P (P-o). Drying altered H2O- and NaHCO3-extractable P-i but had no consistent effect on P-o in these fractions. This work suggests that variations due to drying should be taken into consideration when evaluating manures for P availability or when comparing data in which different drying methods have been utilized.

The focus of this research was to investigate the N-mineralization rates of different soil types in Coastal Plain soils and compare them to a soil from Illinois. Soils with and without dairy composted manure addition were subjected to different wetting/drying cycles [constant moisture at 60% water-filled pore space (WFPS) and cycling moisture from 60 to 30% WFPS] under laboratory conditions at three different temperatures (I VC, 18 degrees C, and 25 degrees C. Samples were collected from three different soil types: Catlin (Mollisols), Bama (Ultisols), and Goldsboro (Utilsols). Soil chemical and physical properties were determined to help assess variations in N-mineralization rates. Addition of composted manure greatly impacted the amount of N mineralized. The amount of manure-derived organic N mineralized to inorganic forms was mainly attributed to the soil series, with the Catlin (silt loam) producing the most inorganic N followed by the Goldsboro (loam) and then Bama (sandy loam). This was probably due to soil texture and the native climatic conditions of the soil. No significant differences were observed between the constant and cycling moisture regimens, suggesting that the imposed drying cycle may not have been sufficient to desiccate microbial cells and cause a flush in N mineralization upon rewetting. Nitrogen mineralization responded greatly to the influence of temperature, with the greatest N mineralization occurring at 25 degrees C. The information acquired from this study may aid in predicting the impact of manure application to help increase N-use efficiency when applied under different conditions (e.g., climate season) and soil types.

In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects of a one-time, fall application of 29 or 72 Mg ha(-1) of dry manure or 22 or 47 Mg ha(-1) of dry compost on subsequent silage yield and nitrogen (N) uptake from previously eroded, sprinkler-irrigated hill slopes were evaluated. In October 1999, stockpiled or composted dairy manure was disked to a depth of 0.15 m into plots with slopes from 0.8 to 4.4%. After planting field corn in 2000 and 2001, a low-pressure, six-span traveling lateral sprinkler system was utilized to apply water at 28 mm h(-1) in amounts sufficient to satisfy evapotranspiration to 6.4- x 36.6-m field plots. Yields in 2000 were 27.5 Mg ha(-1), similar among all rates of all amendments and a fertilized control. In 2001, compost applied at oven-dry rates up to 47 Mg ha(-1) increased yield compared to controls. Silage yield in 2001 increased initially then decreased with increasing manure applications. Where compost or manure was applied, regardless of rate, 2-year average N uptake was 15% greater than controls. Regardless of treatment or year, yields decreased linearly as soil slope increased.

Plant species that both take up As and are appropriate for the climate and growth conditions of the region are needed for phytoremediation to be successfully employed. Actively growing plants from 22 species of native genera were exposed to As in hydroponics systems (either 0, 10, or 50 mg As L-1; 1 week) and commercially available potting mix (either 0, 10, 25, 100, or 250 mg As L 21; 2 weeks), depending on their growth conditions. Aboveground plant tissues were harvested and digested, and concentrations of As were determined by inductively coupled plasma - optical emission spectrometry. The highest tissue concentrations of As (mg As kg(-1) dw) were recorded in seven plant species: Rudbeckia hirta (661), Helenium autumnale (363 in tissues formed after exposure to As), Lupinus perennis (333), Echinacea purpurea (298), Coreopsis lanceolata (258), Lepidium virginicum (214), and Linum lewisii (214). These seven species are ecologically diverse, which suggests that phytoremediation of As using diverse assemblages of plants may be an option for a variety of environments.

A study was conducted in Alabama's Sand Mountain region from 1998 to 2000 to determine tillage and forage systems best suited for removing nutrients from such overloaded soils. Tillage treatments included no-till, moldboard plowing, chisel plowing, and each combined with paraplowing. Forage treatments included bermudagrass (Cynodon dactylon (L.) Pers.) cv. Russell, tall fescue (Festuca arundinacea Schreb.) cv. Kentucky-31, and an annual rotation of ryegrass (Lolium multiflorum Lam.) and sorghum sudangrass (Sorghum bicolor L. Moench x Sorghum vulgare sudanense). The annual rotation produced highest yields and P uptake. Moldboard plowing the annual rotation further increased yields. It appears the annual rotation best removes P, Cu, and Zn via plant uptake. Tillage reduced P concentrations in the soil surface in the following order: moldboard. chisel. no-till.

Compared to conventional-tillage cotton, other treatments had 3.4 to 7.7 Mg ha(-1) more carbon (C) over all soil depths. The particulate organic matter C (POMc) accounts for 29 to 48 and 16 to 22% of soil organic C (SOC) for the 0- to 3- and 3- to 6-cm depths, respectively. Tillage had a strongth influence on POMc within the 0- to 3-cm depth, but cropping intensity and cover crop did not affect POW A large stratification for microbial biomass was observed varing from 221 to 434 and 63 to 110 mg kg(-1) within depth of 0-3 and 12-24 cm respectively. The microbial biomass is a more sensitive indicator (compared to SOC) of management impacts, showing clear effect of tillage, rotation, and cropping intensity. The no-tillage cotton double-cropped wheat/soybean system that combined high cropping intensity and crop rotation provided the best soil quality. C1 [Motta, Antonio C.

We investigated the effects of temperature on the community of mites and fungi associated with the southern pine beetle, Dendroctonus frontalis, an important pest of pine forests in the southern United States. First, we determined whether the growth rates of mutualistic and antagonistic fungi associated with D. frontalis differed in their responses to temperature. Second, we tested the effects of temperature on the abundance of, and interactions among, fungi, mites and beetles within D. frontalis-infested trees. Fungi differed in their growth responses to temperature, resulting in changes in fungal-beetle associations. Mite species associated with D. frontalis also differed in their responses to temperature, resulting in different mite communities associated with bark beetle progeny. The effects of temperature on beetle reproduction could not be assessed because of high wood borer density, but inter-relations among surviving beetles, mites and fungi were altered by temperature. Results support the hypothesis that temperature can produce direct and indirect effects on the web of mutualistic and antagonistic relationships within the community of D. frontalis and their symbiotic mites and fungi.

In this study, we examined plant responses to simulated red deer (Cervus elaphus L.) grazing using clip-plot experiments in a subalpine grassland ecosystem of the Central European Alps. We measured aboveground net primary production (ANPP) and phosphorus (P) concentration of leaf tissue from plants of two vegetation types with different grazing history. The experimental plots were placed on a soil-P gradient and subject to two different clipping treatments, which simulated moderate and heavy grazing, respectively. We found distinct differences in the response of both ANPP and P concentration in leaf tissues in the two vegetation types. Compared to moderate, heavy grazing simulation did not affect ANPP in the vegetation type adapted to grazing, but decreased ANPP in the non-grazing adapted vegetation type. High soil-P levels also had different effects on the response of the vegetation to clipping in the two vegetation types with different grazing history. ANPP correlated positively with soil-P in non-grazing adapted tall-grass vegetation, while in grazing adapted short-grass vegetation a positive relationship between soil-P and the P concentration in leaf tissues was found. Our experiments provide data for a better understanding of ecosystem processes in high-elevation grasslands of the Alps with possible implications for both nature conservation purposes in protected areas and the management of agriculturally used grasslands.

Catfish (11.7 +/- 1.0 g) treated with recombinant bovine growth hormone (rbGH) and challenged with E. ictaluri experienced similar mortality as control-exposed fish. Plasma activity of lysozyme was higher (P < 0.01) in rbGH-exposed fish. Compared to day 0 controls (non-exposed fish), IGF-I levels decreased (P < 0.05) in challenged fish while levels were similar (P > 0.10) between treatments. Abundance of GH receptor (GHR) mRNA tended to decrease (P=0.055) in liver of challenged fish while toll like receptor 5 (TLR5) mRNA increased (P < 0.05) in liver compared to d 0 controls. An increase in lysozyme may suggest GH enhances a nonspecific immune response. A decrease in GHR mRNA and plasma IGF-I suggests a downregulation of the sornatotropic axis in response to disease. The increase in TLR5 mRNA suggests that TLR5 may play a role in host response to bacterial challenge. While exogenous rbGH may play a stimulatory role to increase lysozyme levels, there was no apparent effect of rbGH on mortality to E. ictaluri. (c) 2006 Elsevier Inc. All rights reserved.

Therefore, proteinase activities from gut extracts of Bt-susceptible (YDK) and -resistant (YHD2-B, CXC and KCBhyb) Heliothis virescens strains were compared. The overall pH of gut extracts from YDK and CXC were statistically similar (9.56 and 9.62, respectively), while the pH of extracts from KCBhyb and YHD2-B were significantly more alkaline (9.81 and 10.0, respectively). Gut extracts from YHD2-B and CXC larvae processed Cry1Ac and Cry2Aa protoxin slower than extracts from YDK larvae, suggesting that differences in proteolysis contribute to resistance in these strains. Casein zymogram analysis of gut extracts revealed both qualitative and quantitative differences in caseinolytic activities among all strains, but the overall caseinolytic activity of YED2-B gut extract was lower. Kinetic microplate assays with a trypsin substrate (L-BApNA) demonstrated that proteinases in YDK gut extract had increased alkaline pH optima compared to resistant strains YHD2-B, CXC and KCBhyb. Gut extracts from YHD2-B had reduced trypsin-like activity, and activity blots indicated that YHD2-B had lost a trypsin-like proteinase activity. In assays with a chymotrypsin substrate (SAAPFpNA), enzymes from all Bt-resistant strains had increased pH optima, especially those from KCBhyb. Activity blots indicated that CXC had lost a chymotrypsin-like proteinase activity. Because serine proteinases are a critical component of Bt toxin mode of action, these differences may contribute to decreased toxicity in the Bt-resistant strains. (c) 2006 Elsevier Inc.

Shrews were found to be infected with L3 at Suloia Lake, Southeastern Alaska. Togiak National Wildlife Refuge, southwestern Alaska, and at the Yukon-Charley Rivers National Preserve near the Yukon-Alaska border. Larvae in shrews from Alaska were morphologically indistinguishable from those known in both insectivores and arvicoline rodents from Russia. The occurrence of S. baturini in Alaskan insectivores further establishes shrews as important hosts in the transmission of S. baturini among mustelids and other carnivores and indicates for the first time the basis for a paratenic cycle in the Nearctic.

The mixture of epoxidized soybean oil (ESO) and epoxy resin are modified with a gelling agent to solidify the materials until curing occurs. The high strength and stiffness composites are formed through fiber reinforcement. Glass, carbon and mineral fibers are used in the formulations. It is shown that the fiber orientation follows the direction of motion of the write head that deposits the resins and has a large influence on the properties of the composite. In addition, the effects of curing agents, curing temperature, epoxy/ESO ratio, and fiber loading on mechanical properties of composites are studied and reported. (c) 2006 Elsevier Ltd.

Soy spent flakes is a plentiful renewable material from the waste stream of commercial soy protein extraction. SSF contains mostly soy carbohydrate and dry SSF increases rubber modulus significantly. The aqueous dispersions of SSF and CB were first mixed and then blended with styrene-butadiene latex to form rubber composites by freeze-drying and compression molding method. The mixtures of SSF and CB at three different ratios are investigated as co-fillers. A 30% co-filler reinforced composite exhibits about 100 times increase in the shear elastic modulus compared with unfilled SB rubber, showing a significant reinforcement effect by the co-filler. Compared with the SSF composites, the recovery behaviors of the co-filler composites after the eight consecutive deformation cycles of dynamic strain are improved and are similar to that of the CB composites. The comparison of viscoelastic properties of the composites prepared by freeze-drying and casting methods indicates the composites prepared by freeze-drying method have a lower elastic modulus, but have a better recovery behavior due to its polymer mediated filler network structure. The co-filler composites with 50-75% substitution of CB by SSF have a greater elastic modulus than the CB reinforced composites. Published by Elsevier Ltd.

The mechanical properties of APCs with five different fiber-loadings were evaluated at the room temperature, 4 degrees C, and 40 degrees C. Environmental effects on the mechanical properties of APCS were experimentally quantified after conditioning the APCs with two different fiber-loadings in the following temperature and humidity for over 7000 h: (1) hot/dry at 40 degrees C and 30% relative humidity (RH), (2) hot/wet at 40 degrees C and 82% RH, (3) cold/dry at 4 degrees C and 30% RH, and (4) cold/wet at 4 degrees C and 82% RH. The tensile moduli, flexural moduli, and the flexural strength increased as the woodfiber content increased in the composites. However, the tensile strength decreased as the fiber content increased. The tensile strength was shown to slightly improve with an addition of a. coupling agent between the aspen fibers and polypropylene. The simple empirical micromechanics Halpin-Tsai model for randomly distributed short fiber reinforced composites was employed to predict the homogenized elastic moduli of APC, by optimizing the interfacial model parameter. Scanning electron microscopy (SEM) micrographs confirmed that an addition of the adhesion promoter maleated anhydride polypropylene (MAPP) between the aspen fibers and polymeric matrix improved the interfacial bonding.

This species is locally abundant, but ranked G2/S2-imperiled because of threats to its habitat and a small number of populations-according to Nature-Serve's standardized ranking system. Leaf tissue from ten populations was analyzed with ISSR (Inter-Simple Sequence Repeat) markers to discern the amount of genetic diversity and degree of population subdivision in P. bellii. Genetic diversity was moderate (0.22) and a moderately high degree of population structure was found (F-ST calculated using two algorithms ranged from 0.17 to 0.24). An AMOVA partitioned most of the variation among individuals within populations (76%), and the remainder among populations (24%). Results from a Principal Coordinates analysis were consistent with the geographic distribution of populations. A Mantel test of the correlation between genetic and geographic distances was highly significant (P < 0.001). The pattern of variation thus appears to be distributed along a gradient, and efforts to conserve this species should involve preserving enough populations so that gene flow between populations is not interrupted.

The loser gives up a fraction of its wealth to the winner. That fraction is its parameter. By hypothesis and empirical inference, that fraction scales inversely with the particle's productivity of wealth. Long term wealth flows to particles that lose less when they lose, robust losers, nourishing their further production of wealth. Given a survival function that is an increasing function of wealth, the more robust loser is more losses away from death (Gambler's Ruin) at any given amount of wealth than others. As the level of productivity rises among particles, holding the global mean of wealth constant, expected particle wealth in each productivity equivalence class decreases and the variance of wealth in each equivalence class decreases, i.e., the transfer of wealth from the less to the more productive occurs more efficiently making wealth a better indicator of productivity. As productivity in the IP's population of particles increases, the IP's penalty for low productivity increases, further incentivizing an increase in productivity. The IP operates with no information about how wealth is produced and consequently adapts fluidly to higher productivity, change in constraints on wealth production, and variation in global mean wealth. The IP is a dynamic attractor for a population, maximizing wealth production, minimizing extinction risk. It thus is an evolutionary process in an interdependent population, a colony of organisms, in which each organism depends on the product of the whole population.

TI Wind-driven surficial oxygen transfer SO CRITICAL REVIEWS IN ENVIRONMENTAL SCIENCE AND TECHNOLOGY LA English DT Review ID GAS TRANSFER VELOCITIES; MASS-TRANSFER COEFFICIENT; AIR-WATER-INTERFACE; SWINE WASTE-WATER; CONSTRUCTED WETLANDS; SULFUR-HEXAFLUORIDE; BOMB RADIOCARBON; CARBON-DIOXIDE; DINITROGEN GAS; NITROUS-OXIDE AB Wind- driven surficial oxygen transfer into stationary water bodies has become increasingly important because the fate of many pollutants in these water bodies is strongly influenced by oxygen mass transfer. There are many existing correlations that can be used for predicting wind- driven surficial oxygen transfer; however, the actual prediction has been difficult because there are large variations among numerous predictive transfer coefficient correlations. As a result, selecting an equation that can relate well to certain application conditions becomes critical for accurately predicting surficial oxygen transfer rates. To facilitate the selection process, this article critically reviews and analyzes many of wind- driven surficial oxygen transfer coefficient correlations published during the last five decades. These correlations are for oxygen and other pertinent gas transfer into nonmoving, open water bodies. Empirically derived oxygen coefficients were evaluated using the data derived from investigations in controlled wind tunnels, floating reaeration devices in open waters, and natural open waters. To compare these gas transfer coefficient correlations, gases were normalized to oxygen, and wind speeds were normalized to 10- m height. Generally, low wind speed did not significantly influence the transfer coefficients; however, the transfer coefficients increased, even exponentially, with higher wind speeds. Recently, a new unified equation was developed based on the gas transfer data published in the last five decades to estimate surficial oxygen transfer into stationary water bodies. Although this new equation satisfactorily fits the 50-year data using wind speed as a major variable, the effects of other environmental factors such as wind direction, solid contents, and precipitation need further research.

This article examines the utility of chimeric proteins with capture and clearance domains as a novel countermeasure against pathogens and their toxins. The capture and clearance domains are chosen from the large repertoire of host defense peptides and proteins. Although individual capture and clearance domains are rendered ineffective by pathogenic resistance mechanisms, chimeric scaffolds can be designed to retain their antimicrobial activity, even in the face of pathogenic resistance. Here, initial studies on the design of chimeric proteins targeted against (1) intact bacteria such as Xylella fastidiosa (plant pathogens), Salmonella spp. (food-borne pathogens), and Stapbylococcus aureus (blood-borne pathogens); and (2) lethal toxins from Bacillus anthracis are described.

The genetic basis of biomass production is unknown but asssumed to be complex. We developed a full sib, F, mapping population of autotetraploid Medicago sativa (alfalfa) derived from an intersubspecific cross that was known to produce heterosis for biomass production. We evaluated the population for biomass production over several years at three locations (Ames, IA, Nashua, IA, and Ithaca, NY) and concurrently developed a genetic linkage map using restriction fragment length polymorphism (RFLP) and simple sequence repeat (SSR) molecular markers. Transgressive segregants, many of which exhibited high levels of heterosis, were identified in each environment. Despite the complexities of mapping within autotetraploid populations, single-marker analysis of variance identified 41 marker alleles, many on linkage groups 5 and 7, associated with biomass production in at least one of the sampling periods. Seven alleles were associated with biomass production in more than one of the sampling periods. Favorable alleles were contributed by both parents, one of which is from the M. sativa subsp. falcata germplasm. Thus, increased biomass production alleles can be gleaned from unadapted germplasm. Further, the positive quantitative trait locus (QTL) alleles from the parents are partially complementary, suggesting these loci may play a role in biomass production heterosis.

SO CROP SCIENCE LA English DT Article ID HETEROSIS AB Hybrids between Medicago sativa subsp. falcata and M. sativa subsp. sativa can result in high levels of heterosis for alfalfa forage production. However, commercially viable alfalfa cultivars also must have acceptable performance for other agronomic traits, including regrowth following harvest and appropriate autumn dormancy. In this study, we characterized an F, population derived from the cross of the two subspecies for the genetics of forage production, forage height, and forage regrowth at three harvests in two Iowa locations for 1 yr. Quantitative trait loci (QTLs) controlling these traits were mapped on a genetic linkage map developed from this population. Broad-sense heritabilities and genetic correlations among the traits were high. Marker alleles associated with QTLs for these traits were contributed by each parental genome, suggesting that both subspecies of cultivated alfalfa may contribute to the improvement of these traits. Multiple regression models accounted for between 11 and 44% of the trait variation. The most marker-trait associations were detected during the first harvest. Marker effects were generally similar across harvests. Markers associated with autumn regrowth tended to be different from those associated with regrowth earlier in the season, suggestive of the identification of autumn dormancy effects. The winter hardiness gene MsaciB is a candidate locus for yield and regrowth, being associated with yield across three harvests and with autumn regrowth. A subset of alleles was associated with more than one of the traits. Major alleles for the three traits appear to reside primarily on linkage groups (LGs) 3, 4, 5, and 7.

Merr.] when soil water availability is limiting are (i) water use efficiency (WUE), (ii) regulation of whole plant water use in response to soil water content, and (iii) leaf epidermal conductance (g(e)) when stomata are closed. Six soybean plant introductions (PIs), eight breeding lines derived from them, and nine cultivars were compared for variability in these three traits during vegetative growth in two greenhouse studies. In the first experiment, whole plant water use, normalized both to plant size and evaporative demand (the normalized transpiration ratio, NTR), was monitored during a 10-d cycle of gradually increasing drought stress and then for an additional 2 d following rewatering. The critical soil water content at which each plant began to reduce its water use (FIFSWC), was determined. The WUE was estimated as the ratio of total plant dry weight to total water used. In the second experiment, ge was determined for these same 23 genotypes by measuring leaf water vapor exchange after a 36-h dark adaptation. Substantial variation was found among genotypes for WUE, FTSWC, g(e), and also the extent to which NTR recovered on rewatering. Generally, adapted cultivars had greater WUE and lower g. than did PIs. However, PI 471938 and its progeny N98-7264 were clear exceptions to this trend. An unexpected finding was that WUE was significantly negatively correlated With ge across genotypes.

SO CROP SCIENCE LA English DT Article ID ROW WIDTH; GRAIN-YIELD; GRASSES; HYBRIDS; GROWTH; NITROGEN; SORGHUM; MAIZE; DATE AB The density at which a crop is grown is known to affect its growth and quality, but little is known about how plant density affects the growth of native perennial forage grasses. The objectives were to investigate the effects of plant population density on the forage yield, forage quality, and plant canopy structure of two native bluestem species. Big bluestem (Andropogon gerardii Vitman) and sand bluestem (A. hallii Hack.) were established at six plant densities (1.2, 1.8, 2.7, 3.6, 5.4, and 10.8 plants m(-2)) in a split plot experiment with whole plots in four randomized blocks. Plant density was the main plot and bluestem species was the split plot Data were analyzed with a mixed model analysis of variance with blocks within year as random effects and year as a repeated measure. The optimum plant density for forage production was between 3.6 and 5.4 plants m(-2). However, the optimum for crude protein (CP) concentration occurred at 1.2 and 10.8 plants m(-2) and followed a quadratic response as plant density increased. The greatest leaf area index (LAI; leaf area per square meter) was at 10.8 plants m(-2). At 10.8 plants m(-2), the average yield loss from maximum was about 8.5% dry matter (DM). Also, the CP concentration was 8.5% greater for plants grown at 10.8 plants m(-2) than for those grown at 3.6 to 5.4 plants m(-2). A plant density of 10.8 plants m(-2) would produce high quality forage with only slight reductions in DM yield as compared with plants grown at 3.6 to 5.4 plants m(-2).

The genetic base of modern upland cultivars is narrow. As yield and fiber quality traits are improved, the genetic base should be extended by the incorporation of new germplasm into cultivars. In this study, 114 day-neutral derived primitive accessions were crossed to two cultivars, Stoneville 474 and Sure-Grow 747 (female parents). In a 2-yr study, parents and F-2 hybrids were evaluated in field plots where agronomic and fiber traits were measured. An extended additive-dominance genetic model was used, and the data were analyzed on the basis of the mixed model approach. Dominance effects were the primary genetic effects controlling agronomic and fiber traits, while additive effects were small for most of these traits. Consequently, strong heterosis in some F, and F2 hybrids for most traits would be expected. The genetic resources from the primitive accessions, determined on the basis of cluster analyses, did not show any consistent pattern for collection location or taxonomic classification. Even though dominance effects were the most common for traits measured, results indicate that these day-neutral derived primitive accessions provide genes with significant additive effects for fiber quality traits, while the additive effects for yield improvement was not significantly decreased. Thus, these derived germplasm accessions can provide favorable gene resources for developing high yielding cultivars or hybrids with improved fiber quality.

Merrill] plant introductions (PIs) are potential sources of useful genes for breeding. We mapped quantitative trait loci (QTL) for yield and other agronomic traits, and determined QTL X environment (QTL X E) and epistatic interactions for yield in three backcross (BC) populations. The populations were developed using PIs as donor parents and 'Beeson 80', 'Kenwood', and 'Lawrence' as recurrent parents (RP). Sixty-eight BC2F5-derived lines in the Beeson 80 population, 74 BC1F5-derived lines in the Kenwood population, and 94 BC3F2-derived lines in the Lawrence population were tested along with the RP and checks in 2003 and 2004. Nineteen QTL for three other agronomic traits were identified, as well as 13 yield QTL. The yield-increasing allele was from the PI parent for eight yield QTL. Yield-increasing alleles were associated with delayed maturity for three yield QTL, and one allele was associated with increased lodging and plant height. All yield QTL mapped to regions where yield QTL have been reported previously. The significant QTL X E interaction was due to undetectable or weak QTL effects in some environments. Nine digenic interactions for yield were detected in the Kenwood population, and were mostly between loci exhibiting epistatic effects only. Our results support previous findings that the current elite North American soybean gene pool is more diverse than would have been predicted by the number of contributing ancestors.

TI Soybean rust resistance derived from Glycine tomentella in amphiploid hybrid lines SO CROP SCIENCE LA English DT Article ID PHAKOPSORA-PACHYRHIZI; INTERSUBGENERIC HYBRIDS; LEAF RUST; YIELD AB Soybean rust (SBR), caused by the fungal pathogen Phakopsora pachyrhizi Syd., has the potential to cause significant economic yield loss in U.S. soybean production. Four single dominant resistance genes have been identified in soybean [Glycine mar (L.) Merr.] that only confer specific resistance to a few rust isolates that have been tested. Additional resistance genes have been identified in wild perennial relatives, including G. tomentella Hayata (accession PI 483218, 2n = 78). Intersubgeneric hybrids have been created between G. mar (cv. Altona) and this G. tomentella accession. Amphiploid hybrid lines (2n = 118) were the result of this hybridization and when further backcrossed to G. max (cv. Clark 63), derived fertile lines (2n = 40) were also generated. Both sets of progeny were screened at the USDA-ARS facility at Ft. Detrick, MD, to determine if the resistance to SBR was inherited in the subsequent populations. The amphiploid hybrid clones still retained the genetic SBR resistance that was found in the G. tomentella parent. However, the derived fertile lines were susceptible. These lines were not screened for SBR resistance following each backcross, which may explain this occurrence. Reinstituting the backcross procedure, while testing for SBR resistance at every generation, could move the SBR resistance gene(s) from G. tomentella to the cultivated soybean G. max.

TI Interseeding novel cool-season annual legumes to improve bermudagrass paddocks SO CROP SCIENCE LA English DT Article ID DRYLAND CROPPING SYSTEMS; GREEN MANURE; FORAGE YIELD; PERFORMANCE; BAHIAGRASS; MIXTURES; WATER AB Interseeding nontraditional, cool-season legumes into bermudagrass [Cynodon dactylon (L.) Pers.] paddocks was evaluated as an approach to increasing the quality and duration of forage production and replacing a portion of the N fertilizer required in the southern Great Plains. We compared the effects of interseeding either grass pea (Lathyrus sativa L. 'AC-Greenfix') or lentil (Lens culinaris Med. 'Indianhead') with N fertilizer rates of 0, 45, or 90 kg ha(-1) N. All plots received 60 kg P2O5 ha(-1) in early March. The legume and fertilizer treatments were imposed in mid-March during 2001, 2002, and 2003. Forage samples were clipped from 0.25 m(-2) quadrats on five sampling dates between 1 May and 15 July each year. Yield, N concentration, species composition, and in vitro digestible dry matter (IVDDM) were determined. Year, sampling date, and treatment showed significant (P < 0.05) effects, as did the two-way interactions between all three factors. Total end-of-season standing dry matter of bermudagrass and grass pea was 5550 +/- 423 (SEM) kg ha(-1), which was similar to biomass production with 5 kg ha(-1) N (5305 +/- 570 kg ha(-1)) and less than that produced with 90 kg ha(-1) N (7785 +/- 725 kg ha(-1)). Forage N and IVDDM concentrations for the grass pea treatment were 34 and 6% higher than for bermudagrass, but N and IVDDM concentrations of the forage mixture were intermediate between the higher N rates. Although additional studies are needed to optimize management for the interseeded legumes, we conclude that this practice can improve the quality and duration of bermudagrass forage production in this region.

TI QTL analysis of ICA bunsi-derived resistance to white Mold in a pinto x navy bean cross SO CROP SCIENCE LA English DT Article ID PHASEOLUS-VULGARIS L; SCLEROTINIA-SCLEROTIORUM; PHYSIOLOGICAL RESISTANCE; DRY BEANS; REGISTRATION; INHERITANCE; DISEASE; IDENTIFICATION; POLYMORPHISM; AVOIDANCE AB Breeding for genetic resistance to white mold [Sclerotinia sclerotiorum (Lib.) de Bary] in dry bean (Phaseolus vulgaris L.) is difficult because of low heritability. To facilitate breeding, researchers have sought to identify QTL underpinning genetic resistance to white mold. We identified two QTL conditioning ICA Bunsi-derived resistance to white mold in a pinto X navy bean (Aztec/ND88-106-04) recombinant inbred line (85 RILs) population. ND88-106-04 is a navy breeding line with resistance to white mold derived from ICA Buns' navy. Aztec pinto is susceptible. The QTL were located to linkage groups B2 and B3 of the core map. The B2 QTL expressed in three of four field environments explaining 24.7, 9.0, and 8.7% of the phenotypic variation for disease severity score. The B3 QTL expressed in two of four environments, explaining 15.7 and 5.3% of the phenotypic variation. The B2 QTL was identified previously in ICA Bunsi X navy and ICA Bunsi X black bean RIL populations. The resistance conferred by the B2 QTL has a physiological basis due to association with stay green stem trait and lack of association with disease avoidance traits. The B3 QTL, undetected in previous studies, was associated with disease avoidance traits (canopy porosity, plant height), stay green stem trait, and maturity. The B2 QTL with stable expression in multiple environments and across genetic backgrounds will be most amenable to manipulation by breeders.

TI AFLP-RGA markers in comparison with RGA and AFLP in cultivated tetraploid cotton SO CROP SCIENCE LA English DT Article ID RESISTANCE-GENE ANALOGS; QUANTITATIVE TRAIT LOCI; DISEASE-RESISTANCE; ASSISTED SELECTION; THEOBROMA-CACAO; PCR MARKERS; L.; GENOME; WHEAT; IDENTIFICATION AB Disease resistance (R) genes have been isolated from many plant species and R genes with domains of nucleotide binding sites (NBS) and leucine-rich repeats (LRR) represent the largest R gene family. The objective of this investigation was to test a resistance gene analog (RGA) anchored marker system, called amplified fragment length polymorphism (AFLP)-RGA in cotton (Gossypium spp.). The AFLP-RGA analysis uses one degenerate RGA primer designed from various NBS and LRR domains of R genes in combination with one selective AFLP primer in a PCR reaction. Out of a total of 446 AFLP-RGA bands amplified by 22 AFLP-RGA primer combinations, 76 (17.0%) and 37 (8.3%) were polymorphic within four G. hirsutum L. genotypes and four G. barbadense L. cotton genotypes, respectively. The number of polymorphic AFLP-RGA bands (256) between G. hirsutum and G. barbadense was much higher (57.4%). This level of polymorphism mirrors that of AFLP. The genetic similarity among the eight genotypes based on AFLP-RGA or AFLP lead to similar results in genotype grouping at the species and intraspecies level. However, RGA markers amplified by only degenerate RGA primers could not discriminate several genotypes. AFLP-RGA offers a great flexibility for numerous primer combinations in a genome-wide search for RGAs. Due to the distribution of RGAs or RGA clusters in the plant genome, genome-wide AFLP-RGA analysis provides a useful resource for candidate gene mapping of R genes for disease resistance in cotton.

TI Forage bermudagrass cultivar responses to inoculations with Exserohilum rostratum and Bipolaris spicifera and relationships to field persistence SO CROP SCIENCE LA English DT Article ID LAGOON EFFLUENT APPLICATIONS; COASTAL BERMUDAGRASS; NUTRIENT-UPTAKE; BROILER LITTER; YIELD; REGISTRATION; FERTILIZER AB In the southeastern USA, bermudagrass [Cynodon dactylon (L.) Pers.] is a principal species to which animal wastes are applied for nutrient removal. Diseases caused by Exserohilum, Bipolaris, and Curvularia spp. may limit its effectiveness for this purpose. This study evaluated responses of seven forage bermudagrass cultivars (Alicia, Brazos, Coastal, Common, Russell, Tifton 44, and Tifton 85) to two pathogens, E. rostratum (Drechs.) Leonard & Suggs and B. spicifera (Bain) Subram., and persistence of cultivars with natural infection in the field. All cultivars were susceptible to both pathogens with foliar inoculations, but differed in degrees of susceptibility. Alicia was highly susceptible to both pathogens. Coastal was least susceptible to B. spicifera, but no cultivar was consistently least susceptible to E. rostratum. Persistence of cultivars for up to 1 yr in the field differed and appeared related to both sod density and susceptibility to pathogens. Dense sods appeared to enable cultivars to generate more top growth and compensate for disease losses. Common, Coastal, and Tifton 44 bermudagrasses were most persistent in the field; Tifton 85 and Alicia were least persistent. Results indicate that resistance to dematiaceous hyphomycetous pathogens, along with a strong sod-forming ability, is desirable in forage bermudagrass cultivars to sustain their persistence and productivity on animal waste application sites.

T2BS.2RL translocations were shown to increase grain yield, resistance to biotic and abiotic stresses, and had minor effects on baking quality. The objective of this study was to test agronomic performance and resistance of a new wheat-rye translocation (T2BS.2RL, SLU) to powdery mildew (Blumeria graminis E sp. tritici (DC.) E. O. Speer), leaf rust (Puccinia triticina Eriks.), stem rust (Puccinia graminis f. sp. tritici Eriks. & Henn.), stripe rust (Puccinia striiformis f. sp. tritici Westend.) and Hessian fly [Mayetiola destructor (Say)]. F-2 derived F-4-F-6 T2BS.2RL lines, non-translocation lines, and the wheat cultivar Holme were compared using intact seedlings or leaf segments. T2BS.2RL conferred seedling resistance to 17 powdery mildew isolates, 14 leaf rust and one stem rust pathotype. The T2BS.2RL lines were susceptible to 3 stripe rust pathotypes as seedlings, while showing adult plant resistance under natural conditions. Agronomic characters were compared in a 2-yr hill-plot field trial in Sweden. T2BS.2RL lines flowered 2 to 3 d later and had an increased number of spikelets per spike. The T2BS.2RL had no significant effect on yield, straw length, lodging, volume weight, 1000-kernel weight, fertility, alpha-amylase activity, or starch or protein content. The multiple disease resistance and the minor negative effects on agronomic performance of the T2BS.2RL, SLU translocation encourage its use in wheat breeding.

TI Molecular analysis of soybean lines with low palmitic acid content in the seed oil SO CROP SCIENCE LA English DT Article ID SELECTION; GENES; INHERITANCE; MUTANTS; REGISTRATION AB Palmitic acid is the major saturated fatty acid found in soybean [Glycine mar (L.) Merr.] oil, accounting for approximately 11% of the seed oil content. Reducing the palmitic acid levels of the oil is desirable because of the negative health effects specifically associated with this fatty acid. One of the genetic loci known to reduce the seed palmitate content in soybean is fap(nc). Previous studies indicated that fap(nc) is associated with a deletion in a gene (designated FATB) encoding 16:0-ACP thioesterase activity. In this report, we isolated full length cDNAs of three of the four unique FATB genes expressed in soybean and show that the isoform designated GmFAT1a represents the specific gene deleted in lines possessing the fap(nc) locus. Allele specific primers corresponding to GmFATB1a were used to genotype plants from two F4-derived populations that were segregating for fap(nc). The GmFATB1a-specific markers were effective in accounting for 62 to 70% of the genotypic variation in palmitate content in the two populations studied. Because the markers developed in this study are 100% linked to the locus of interest, they should be particularly useful in marker-assisted selection programs designed to lower the palmitic acid levels of soybean oil.

Traditionally, dual-purpose (grazing plus grain) wheat cultivars are developed from a grain-only production system. Because culms of dual-purpose grown wheat may forfeit productivity gains for grainonly developed cultivars, we evaluated N and biomass traits at anthesis and maturity for 112 sets of subpopulations (each set a unique genetic background) to test benefits of making selections from a dual-purpose system. Sets came from F-2 sources and contained a "Base" F-3 bulk population and ITS bulk populations mass selected from the F2 within grain-only and dual-purpose production systems. The 12 sets of subpopulations were evaluated in grain-only and dual-purpose production systems in 2001-2002 and 2002-2003. At anthesis, main effects (year, system, genetic background, subpopulation selection environment) were significant for calm dry weight and N, and flag leaf dry weight. Among selections, differences for these traits were small (2.0-3.5%) with no difference between grain-only and dual-purpose selections; differences among genetic backgrounds, however, were large (21-30%). At maturity, differences (7.6-20%) for grain dry weight and kernel mass, harvest index (HI), N content, grain N, and N harvest index (NHI) of individual culms occurred among genetic backgrounds. Differences among subpopulations were smaller (1.4-4.5%) and significant for only calm and grain dry weight, kernel number and mass, and calm N content. Selections made from the dual-purpose environment performed similar to those from the grain-only environment when grown in either production system.

The objectives were to verify the chromosome location of the ms2 (A00-63) mutation, to determine the allelism and the chromosome location of the suspected ms2 [ms?

Simple sequence repeat (SSR) markers were used to molecularly map the male-sterile, female-fertile loci reported in this study. Segregating F-2 populations were developed from crosses of ms?ms? (A00-39) x 'Minsoy' (PI 278901), ms2ms2 (A00-63) x Minsoy, and Minsoy x Ms9ms9 (T359H). The ms? (A00-39) locus was positioned on MLG O at 9.9 centiMorgans (cM) distance from the marker Sat_190. The ms2 (A00-63) locus was positioned on molecular linkage group (MLG) O between markers Sat_190 and ScaaOO1, with a distance of 6.9 and 9.0 cM, respectively. The ms9 locus was located on MLG N between markers Satt521 and Satt237, with a distance of 8.5 and 16.2 cM, respectively. Classical allelism tests confirmed that mutant ms? (A00-39) was allelic to ms2 (A00-63). The A00-39 mutant line was assigned Genetic Type Collection number T375H and gene symbol Ms2ms2 (Ames 2). Thus Genetic Type T360H, previously identified at Ames, Iowa, becomes Ms2ms2 (Ames 1). C1 Iowa State Univ, Dept Agron, Ames, IA 50011 USA.

As livestock producers seek less capital-intensive production systems, emphasis is redirected toward low-input pasture systems that rely on complex species mixtures to produce forage. Increased plant species diversity has been linked to improvements in ecosystem function. While it is recognized that grazing management can have a profound impact on sward composition, which in turn can affect grazing behavior and animal performance, the effects of increased plant species diversity on animal productivity (and vice versa) have not been well explored. This review addresses mechanisms by which grazing livestock alter cool-season plant species diversity, mechanisms of diet choice, effects of plant species diversity on animal performance, and implications to sustainable domestic livestock grazing systems. We review evidence for these effects at one trophic level, that of grazing livestock in agroecosystems. While grazing behavior research conducted during the last several decades has led to advances in the understanding of plantanimal interactions, improved knowledge of these interactions is crucial for predicting animal performance. Also important is the evaluation of the impact of grazing livestock on mixed sward dynamics. This knowledge will lead to new opportunities to develop environmentally and economically sustainable grazing systems.

Here a framework genetic map is presented that is expandable and transferable to research programs interested in locating their markers on a consensus map. In its current framework, the primary markers used were amplified fragment length polymorphisms (AFLPs) that were anchored to Butterfass chromosome-nomenclature linkage groups using linkage group specific markers validated in other populations. Thus, a common framework has been established that anchors 331 markers, inducing 23 newly mapped simple sequence repeat (SSR) markers, having a combined total of 526.3 cM among the nine beet linkage groups. The source of the mapping population was a sugarbeet x table beet population, and this is the first report of a map constructed with a relatively wide cross in B. vulgoris. Segregation distortion was common (22% of loci), particularly extreme for Butterfass Chromosome 5, and predominantly favored the sugarbeet (seed parent) allele. Physical segments of the beet genome that carry mapped markers have been identified, demonstrating that physical and genetic mapping are facile and complementary applications for beet improvement.

TI The FAD2 gene family of soybean: Insights into the structural and functional divergence of a paleoplyploid genome SO CROP SCIENCE LA English DT Article ID GLYCINE-MAX; ARABIDOPSIS-THALIANA; MEDICAGO-TRUNCATULA; DUPLICATE GENES; MAIZE GENOME; FATTY-ACIDS; SEQUENCES; TEMPERATURE; EVOLUTION; ORGANIZATION AB The omega-6 fatty acid desaturose (FAD2) gene family in soybean [Glycine max (L.) Merr.] consists of at least five members in four regions of the genome and are responsible for the conversion of oleic acid to linoleic acid. Here we report the identification of two new omega-6 fatty acid desaturase (FAD2) gene copies from soybean expressed sequence togs (ESTs). Four bacterial artificial chromosomes (BACs) containing five FAD2 genes were sequenced to investigate structural and functional conservation between duplicate loci. Sequence comparisons show that the soybean genome is a mosaic, with some duplicate regions retaining high sequence conservation in both genic and intergenic regions, while others hove only the FAD2 genes in common. Genetic mapping using SSRs from within the BAC sequences showed that two BACs with high sequence homeology mapped to linkage groups I and 0; these groups share syntenic markers. Another BAC mapped to linkage group L. The fourth BAC could not be mapped. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis of the five FAD2 genes showed that the FAD2-2B and FAD2-2C copies were the best candidates for temperature-dependent expression changes in developing pod tissue. Semiquantitative RT-PCR confirmed these results with FAD2-2C showing upward of an eightfold increase in expression in developing pods grown in cooler conditions relative to those grown in worm conditions. The implications of these results suggest a candidate gene for controlling the levels of linoleic acid in developing pods grown in cooler climates. C1 USDA ARS, CICGR, Ames, IA 50011 USA.

They are mainly synthesized by plants and fungi, and most troponoids play roles of antibacterial defenses in these organisms. With an increasingly severe situation of antibiotic resistant bacteria, as well as a requirement for antifungal medicines, troponoids have attracted extensive studies since they have powerful antibacterial and antifungal activity, particularly against anti biotic-resistant bacteria. In addition, many other biological activities such as antiviral, antitumor, antioxidant, antiinflammatory, insecticidal, or enzyme inhibitor activities are associated with troponoids. After extensive studies in the 1960s-70s, interests in natural troponoids dedclined. However, chemical and biomedical studies on troponoids bloom again from the 1990s. To date great progress has been made with troponoid study in terms of identification of new natural troponoids, chemical synthesis and properties, biological activity, biosynthesis and metabolism. Particularly, bioassay-guided screening strategy and structure-activity relation-directed structure modification and drug design has resulted in the synthesis and discovery of many new derivatives. Many of them have great promise to be developed into new medicines for their potent and specific activities. This review presents the recent advances in troponoid studies and highlights multiple faceted biological activities of troponoids, as well as their relationships with chemical structures. Chemistry, biosynthesis, and production via biotechnology of troponoids are also briefly reviewed. Applications of troponoids in daily life, agriculture, medicine, and industry, and the related patents have been considered to further extend our understanding of the increasing impact of troponoids on humans.

To understand the impact of vitamin K nutrition on healthy aging it is necessary to assess both the determinants and the adequacy of vitamin K nutritional status of the elderly. Recent findings Overall, elderly persons consume more vitamin K than young adults. However, a subgroup of the elderly population does not meet the current recommended dietary intakes for this nutrient. The first meta-analysis evaluating the data on the role of vitamin K and bone health concluded that increased intakes of vitamin K are warranted to reduce bone loss and fracture risk among the elderly. Recent studies suggest that nondietary determinants of vitamin K status need to be factored into any discussion on the adequacy of nutritional status of the elderly. One promising area of research is the interrelationship between estrogen and vitamin K. Summary Evidence is emerging to support recommendations to increase intakes of vitamin K among the elderly to reduce bone loss and fracture risk. Much more research is required, however, to identify nondietary determinants of vitamin K status, and their impact on the elderly.

Recent findings Studies indicate that the gastrointestinal tract metabolizes 20% of dietary methionine and that its main metabolic fate is transmethylation to homocysteine and transsulfuration to cysteine. The gastrointestinal tract accounts for similar to 25% of whole-body transmethylation and transsulfuration and is a site of net homocysteine release. The production of homocysteine within the intestinal mucosa may contribute to the inflammatory response and endothelial cell dysfunction in patients with inflammatory bowel disease. Studies also show that the availability of S-adenosylmethionine as a precursor for methylation reactions and polyamines plays a key role in epigenetic DNA methylation, gene expression and colon carcinogenesis. Cysteine derived from the diet and methionine transsulfuration is a functional constituent of antioxidant systems and impacts several elements of redox status that regulate epithelial intracellular signaling, proliferation and survival. Summary Further studies are warranted to establish how local production of homocysteine, S-adenosylmethionine and antioxidants contributes to the development of gastrointestinal diseases and whether dietary intervention with folate and cysteine is an efficacious approach to prevention and treatment.

TI Evidence for widespread epistatic interactions influencing Marek's disease virus viremia levels in chicken SO CYTOGENETIC AND GENOME RESEARCH LA English DT Article ID QUANTITATIVE TRAIT LOCI; WRIGHT SHIFTING-BALANCE; AFFECTING SUSCEPTIBILITY; GENETIC-VARIATION; CELL CULTURE; TURKEYS HVT; RESISTANCE; HERPESVIRUS; GROWTH; AGENT AB Marek's disease (MD), a T cell lymphoma induced by the Marek's disease virus (MDV), is the main chronic infectious disease concern threatening the poultry industry. Enhancing genetic resistance to MD in commercial poultry is an attractive method to augment MD vaccines, which is currently the control method of choice. In order to implement this control strategy through marker-assisted selection (MAS), it is necessary to identify quantitative trait loci (QTL) or genes that influence MD incidence. Previous studies have demonstrated that it is possible to identify QTL that confer MD resistance in both experimental and commercial chickens. With the advent of the chicken genome sequence and new genomic tools, and evidence that interactions are important in understanding complex traits, the line 6 x 7 F-2 experimental resource population was re-evaluated with finer resolution for epistatic interactions. The F-2 population, consisting of 272 individuals and previously genotyped with 133 genetic markers, was combined along with 576 additional single nucleotide polymorphisms (SNPs) genotyped on 80 individuals in each of the distribution tails for MD and other associated traits, and tested for the presence of main effects and two-way epistatic interactions accounting for MD incidence, viremia titers, and length of survival. Main effects were generally not significant but a large number of highly significant interactions, involving loci located throughout the genome, were identified that account for MDV viremia titers in infected birds. These results suggest that resistance to MD is highly complex and will require the incorporation of epistatic interaction analyses and functional genomic approaches to reveal the underlying genetic basis.

Although phylogenetically related to other vertebrate CD4 molecules, they exhibit only 19% amino acid identity to each other. IpCD4L-1 encodes a predicted protein containing four immunoglobulin domains, a transmembrane region and a cytoplasmic tail containing a p56(lck) binding site. In contrast, IpCD4L-2 encodes for a similar protein with three immunoglobulin domains. The gene organization of IpCD4L-1 is very similar to that of other vertebrate C134 genes, while the genomic organization of IpCD4L-2 is different. Southern blots indicate both catfish molecules are likely single copy genes and mapping studies show that both are found on a single Bacterial Artificial Chromosome suggesting close linkage. At the message level, IpCD4L-1 and -2 are expressed in various catfish lymphoid tissues and in non-B-cell peripheral blood leukocytes (PBL). Both messages are upregulated in concanavalin A (ConA) and alloantigen stimulated PBL, but not in lipopolysaccharide (LPS)-stimulated cultures.

Previously, we demonstrated that trout possess five unlinked regions encoding MH genes. One of these regions harbors ABCB2 which in all other vertebrate classes is found in the MHC class II region. In this study, we sequenced a BAC contig for the trout ABCB2 region. Analysis of this region revealed the presence of genes homologous to those located in the human class II (ABCB2, BRD2, psi DAA), extended class II (RGL2, PHF1, SYGP1) and class III (PBX2, Notch-L) regions. The organization and syntenic relationships of this region were then compared to similar regions in humans, Tetraodon and zebrafish to learn more about the evolutionary history of this region. Our analysis indicates that this region was generated during the teleost-specific duplication event while also providing insight about potential MH paralogous regions in teleosts.

Heterophils were isolated from wild-type Rio Grande turkeys and a commercial line of turkeys (Line A) on days 4 and 7 post-hatch. Heterophils were stimulated for 1 h with Salmonella enteritidis (SE) or opsonized SE (OPSE). After stimulation, cells were lysed and lysates were tested for mitogen-activated protein kinase (MAPK) activity. Specifically, phosphorylation of extracellular signal-regulated protein kinase (ERK1/2) and p38 MAPK phosphorylation were assayed using commercially available ELISA kits. Total protein tyrosine kinase (PTK) activity was also assayed. On both days 4 and 7 post-hatch, heterophils from Rio Grande turkeys had significantly higher levels of ERK1/2 and p38 MAPK kinase activity upon stimulation with either SE or OPSE (p < 0.001). Likewise, PTK values on days 4 and 7 in Rio Grande turkey heterophils were significantly higher upon stimulation with SE than with OPSE and were significantly (p<0.001) higher than PTK levels in Line A upon SE and OPSE stimulation. The data presented supports previous heterophil functional comparison studies wherein heterophils from Rio Grande turkeys had higher levels of oxidative burst and degranulation activities as compared to the activity observed in commercial Line A heterophils. This suggests that the regulation and control of these functions are mediated by protein tyrosine and mitogen-activated kinases. Furthermore, the data suggest that selection of commercial lines of turkeys for larger, heavier bodies, and faster growth may be associated with subsequent selection for decreased innate immune functions related to intracellular signaling mechanisms and possibly a subsequent increase in susceptibility to disease.

TNFSF15 transcripts were primarily expressed in spleen, liver, intestinal intraepithelial lymphocytes (IEL), peripheral blood lymphocytes and bursa. In vitro infection of HTC macrophages with three species of Eimeria sporozoites induced TNFSF15 gene expression. In vivo experiments revealed that TNFSF15 gene was highly increased following primary infections with Eimeria acervulina or Eimeria maxima. In contrast, no consistent changes in transcript levels were seen following primary infection with Eimeria tenella, or following secondary infection with any of the three Eimeria species. Following infection with E. acervulina and E. maxima, TNFSF15 transcripts were primarily expressed in intestinal CD4(+) and TCR2(+) IEL, respectively. A dose-dependent cytotoxic effect of recombinant TNFSF15 protein was observed on HTC and LSCC-RP9 tumor cells. These results indicate that TNFSF15 plays an important role in local inflammatory response to Eimeria. (C) 2007 Published by Elsevier Ltd.

TI The influence of infant diet on early developmental changes in processing human voice speech stimuli: ERP variations in breast and milk formula-fed infants at 3 and 6 months after birth SO DEVELOPMENTAL NEUROPSYCHOLOGY LA English DT Article; Proceedings Paper CT Conference on Cortical Event-Related Potentials and Early Language CY NOV 09-10, 2004 CL USDA Agr Res Serv, Children Nutr Ctr, Little Rock, AR HO USDA Agr Res Serv, Children Nutr Ctr ID EVENT-RELATED POTENTIALS; AUDITORY EVOKED-POTENTIALS; COGNITIVE-DEVELOPMENT; MISMATCH NEGATIVITY; ELECTROPHYSIOLOGICAL EVIDENCE; 4-MONTH-OLD INFANTS; BRAIN POTENTIALS; YOUNG INFANTS; 1ST YEAR; DISCRIMINATION AB The purpose of this investigation was to determine if processing of language stimuli during the first half year of life in breast-fed infants differs from that of formula-fed infants. This question was addressed by examining the brain event-related potentials of healthy infants receiving breast milk (n = 15) or milk-based formula (n = 18) recorded in response to consonant vowel syllables presented in an oddball paradigm. The same infants were studied when they were 3-montlis and 6-months-old. The two groups were comparable on several measures relating to biological and home environment variables previously reported to influence development, including gestation period, birth weight, mother's IQ, and family socioeconomic status, and did not differ in weight or mental or motor development at the times of the visits. In general, ERP response features previously documented in studies of syllable processing in 3-6-month-old infants were observed in this study, including positive components at similar to 190 msec (P1), similar to 370 msec (P2), and similar to 600 msec (P600), and negative components at similar to 250 msec (N250), similar to 450 msec (N450), and a late, negative going slow wave between 655 and 995 msec (LSW). For both groups there were instances where specific components were either poorly defined, e.g., P1 and N250 to the infrequent syllable at 3 months, N450 and P600 to this syllable at both ages,,or not present in many infants, e.g., the P600 to the frequent syllable at 6 months. These variations appeared to be related to individual differences in development or paradigm-related features, i.e., ISI and frequency of syllable occurrence. Developmental variations (changes from 3 to 6 months) common to both feeding groups included latency decreases for P1, decreased P2 amplitude, and increased amplitudes for N250 and LSW components. Within this framework, group differences were detected in areas involving the development of response components, the development of processing capabilities, and syllable discrimination. In all cases, these effects related to components following initial stimulus registration, i.e., to the processing of sound content rather than sound acoustic features. The pattern of these differences suggests advantages for BF infants in the development and processing of language stimuli during the first 6 months of life.

Behavioral assessment was also obtained. A major positive component (P200) was elicited by both types of sounds. It had a maximal scalp distribution in the fronto-central areas in both groups of infants. The mean latencies did not differ between the groups or between the stimulus types. However, the latencies decreased across age in both groups. The mean P200 amplitude in the formula-fed infants was lower than that in the breast-fed infants, but the difference was not significant. The between-stimulus differences in frontal P200 amplitudes were positively correlated with the behavioral scores of Bayley Index of Infant Development. These data suggest that the processing of the present speech stimuli is not affected by the investigated diets in the early infancy.

Analysis and classification of remotely sensed spectral data is an effective method for discerning the spatial and temporal variability of soils. The East Shore Area (ESA) of the Great Salt Lake soil survey update is focused on updating soil map units containing wet and saline soils. The ESA provides a unique environment for the use of remotely sensed spectral data for map unit refinement because of low relief and a large extent of soils that are wet and saline to various degrees. Map units in the ESA containing wet and saline soils were updated and refined using Landsat 7 imagery. Five land-cover classes are related to dominant soil types that vary in soil wetness, salinity, calcium carbonate concentration and vegetation cover type. Supervised classification of the imagery was performed using the five land cover classes. The final classification resulted in 14 land cover classes, including nine additional classes that help describe the variability in the original five classes. The classification results were validated using visual inspection in the field, a priori knowledge of the area and an error matrix. The results of the classification were used to enhance original soil map units and calculate map unit composition in the final soil mapping process. This information was then incorporated into the updated soil map. Temporal variation in land cover classes has the potential to be considered in map-unit refinement to reflect the dynamic nature of the margins of the Great Salt Lake, Utah.

We developed and tested a methodology that incorporates geographic information systems (GIS), remote sensing and modelling to predict and map soil distribution in the Powder River Basin of Wyoming. Based on conceptual models in which unique soils are the products of unique sets of soil-forming factors, topographic data derived from digital elevation models (DEMs) and Landsat 5 spectral data were selected to represent soil-forming factors. These digital data were analysed using commercially available GIS and image processing software. Unsupervised, supervised and simple knowledge-based classifications were used in the preliminary stage to develop visual representations of soil-landscape patterns and to plan for field data collection. As more was learned about the survey area from data collection, a knowledge-based decision-tree classification model was built and refined. The resulting maps were evaluated qualitatively by local experts and quantitatively using accuracy assessment, and showed good agreement between predicted and observed map units. Continued technological advancements in spatial data and improved GIS and modelling expertise of soil scientists should increase the accuracy and efficiency of the soil survey process. C1 [Cole, N.

Soil profile descriptions were obtained within soil survey projects in the Mojave Desert of southeastern California, USA. Sites were located on broad alluvial fans. Soil development varied from young soils with little or no soil development to well-developed soils on older alluvial fan remnants. We obtained a set of profile descriptions (n = 264) from the traditional ongoing fieldwork. The location of these sample points was determined by soil scientist judgment of combinations of soil-forming factors. The project area is sparsely vegetated and access is relatively unimpaired in most areas. We feel that these purposive samples represent the range of the soil-forming factors and that sample location bias will be low. Although this bias is not measurable. We wanted to see if we could make use of these data. We developed models from these data and evaluated the performance of the models using the measured values at randomly located sites not used to fit the models. The models estimated selected soil characteristics continuously in a 30-m raster over the project area. The response variables that we modelled were soil genetic features that are used as diagnostic properties in USDA Soil Taxonomy, for example particle-size class, presence or absence of argillic horizon. Soil profiles and landscape features were described at 97 randomly located field sites within a portion of the active soil survey project. Explanatory variable information was developed for each of these sites through GIS extraction from digital elevation model data, landform derivatives, band-ratio satellite images and geomorphologic data. Model estimates for particle-size class were correct or within one class of the correct class for 73% of sample points. Models for depth to soil features had a range of performance. The best fitting model estimated the depth to secondary carbonates within 20cm of actual depths for 71% of sample points, which contained carbonates. The model for depth to calcic horizon performed less well, while the model for depth to argillic was slightly less reliable. The model for presence or absence of calcic horizon was the most reliable logistic model. Soils on millions of hectares will be mapped in this general area in the future and we are trying to increase mapping efficiency and depth of understanding of soil-landscape relationships. Model development techniques will be adapted and applied to adjacent areas in the future. Further work will require more field data (to document the response variables) and more complete soil-forming factor spatial data. New soil survey products may result from these continuous raster estimates of soil properties. These model outputs are intended to augment and guide field soil survey data collection, not replace it.

A 90-genotype subset of an F-2 population from a cross between these lines was evaluated for genetic linkage using 162 polymorphic SSRs, plant height, pod color ( L2/l2), flower color ( W1/w1) and stem termination ( Dt1/dt1). A 1514cM ( Kosambi) genetic map covering 65% of the soybean genome based on 157 linked SSR markers was created. Comparison with the composite soybean genetic map was used to verify map order. Loci for pod color, flower color and stem termination fell in the expected position on the map indicating this is a normally segregating mapping population. Loci for height were identified on linkage groups C2, D1a, D1b, H, L, M and O. MG IV and V soybean genotypes are critical for the early soybean production system widely used in the midsouthern US. However, only two mapping populations have been reported in Soybase for MGIVand V genotypes. Additionally, the parents used in this cross are known to differ in their response to soybean cyst nematode and charcoal rot, which constitute two major pathology threats to Midsouth soybean production. The population and map reported herein represent an important genetic resource for the early soybean production system.

The product, 9AA, is approximately 27-fold more fluorescent than the substrates using excitation and emission wavelengths of 405 and 455 nm, respectively. Tests using expressed CYP1A1, 1A2, 3A4, 3A5, 1B1, 2C9, 2C19, and 2D6 indicated that N-dealkylase activity is specific for CYP1A1 and CYP2D6. CYP2D6 N-dealkylated methyl, ethyl, n-propyl, and n-butyl substrates, whereas CYP1A1 N-dealkylated these plus the n-pentyl derivative. Activities using 5 mu M 9-N-(alkylamino)acridine substrates ranged from 0.1 to 0.9 pmol 9AA/min/pmol P450. Kinetic constants for CYP1A1 N-dealkylation of the 9-N-(methylamino) acridine (MAA) and 9-N-(ethylamino) acridine (EAA) were K-m 1.09 +/- 0.68 and 0.35 +/- 0.21 mu M and the V-max 61.9 +/- 48.5 and 113.8 +/- 8.4 pmol 9AA/min/ pmol CYP1A1, respectively. Kinetic constants for CYP2D6 N-dealkylation of MAA and EAA were Km 7.9 +/- 5.4 and 3.2 +/- 1.6 +/- mu M, and V-max 501 +/- 35.4 and 702.7 +/- 257 pmol 9AA/min/pmol CYP2D6, respectively. The experimental binding energies (Delta G(bind)) were calculated for MAA with CYP1A1 and CYP2D6 to be -8.266 and -7.074 kcal/mol, respectively. The Delta Gb(ind) values for EAA with CYP1A1 and CYP2D6 were -8.950 and -7.618 kcal/mol, respectively. The substrates were suitable for monitoring N- dealkylase activity in microsomal preparations (human, rat, and monkey hepatic preparations) and human hepatocellular carcinoma cell suspensions. Assays were conducted by monitoring reactions either in 96-well microtiter plates using a fluorescence plate reader or in cuvettes using a spectrofluorimeter.

In this study, a previously established algorithm was applied to WindSat data to estimate global soil moisture. Comprehensive validation was performed by comparing the retrievals with in situ soil moisture observations from networks located at four soil moisture validation sites. The overall standard error of estimate for surface soil moisture was 0.038 m3/m3. This analysis shows that the WindSat soil moisture retrievals are reasonable and fall within the generally accepted error bounds of 0.04 m3/m3. Larger scale qualitative assessments were performed by analysis of the spatial distribution of soil moisture, which were found to be consistent with the known global climatology. There are other soil moisture algorithms under investigation, however, these result show the potential of the WindSat sensor for soil moisture as well as future operational satellite instruments.

Before trampling, control sites had greater cyanobacterial biomass, soil surface stability, threshold friction velocities (TFV; i.e. the wind speed required to move soil particles), and sediment yield than sites that had been more recently disturbed by military manoeuvres. After trampling, all sites showed a large drop in TFVs and a concomitant increase in sediment yield. Simple correlation analyses showed that the decline in TFVs and the rise in sediment yield were significantly related to cyanobacterial biomass (as indicated by soil chlorophyll a). However, chlorophyll a amounts were very low compared to chlorophyll a amounts found at cooler desert sites, where chlorophyll a is often the most important factor in determining TFV and sediment yield. Multiple regression analyses showed that other factors at Fort Irwin were more important than cyanobacterial biomass in determining the overall site susceptibility to wind erosion. These factors included soil texture (especially the fine, medium and coarse sand fractions), rock cover, and the inherent stability of the soil (as indicated by subsurface soil stability tests). Thus, our results indicate that there is a threshold of biomass below which cyanobacterial crusts are not the dominant factor in soil vulnerability to wind erosion. Most undisturbed soil surfaces in the Mojave Desert region produce very little sediment, but even moderate disturbance increases soil loss from these sites. Because current weathering rates and dust inputs are very low, soil formation rates are low as well. Therefore, soil loss in this region is likely to have long-term effects.

We conducted an assessment of some of the ecological and socioeconomic effects of recently enacted forest management policies in the 2.3-million-ha Coast Range Physiographic Province of Oregon. This mountainous area of conifer and hardwood forests includes a mosaic of landowners with a wide range of goals, from wilderness protection to high-yield timber production. We projected forest changes over 100 years in response to logging and development using models that integrate land use change and forest stand and landscape processes. We then assessed responses to those management activities using GIS models of stand structure and composition, landscape structure, habitat models for focal terrestrial and aquatic species, timber production, employment, and willingness to pay for biodiversity protection. Many of the potential outcomes of recently enacted policies are consistent with intended goals. For example, we project the area of structurally diverse older conifer forest and habitat for late successional wildlife species to strongly increase. Other outcomes might not be consistent with current policies: for example, hardwoods and vegetation diversity strongly decline within and across owners. Some elements of biodiversity, including streams with high potential habitat for coho salmon (Oncorhynchus kisutch) and sites of potential oak woodland, occur predominately outside federal lands and thus were not affected by the strongest biodiversity policies. Except for federal lands, biodiversity policies were not generally characterized in sufficient detail to provide clear benchmarks against which to measure the progress or success. We conclude that land management institutions and policies are not well configured to deal effectively with ecological issues that span broad spatial and temporal scales and that alternative policies could be constructed that more effectively provide for a mix of forest values from this region.

However, current knowledge about patterns of vegetation variability across large regions that is spatially explicit (i.e., mapped) tends to be general and qualitative. We used spatial predictions from gradient models to examine the influence of environment, disturbance, and ownership on patterns of forest vegetation biodiversity across a large forested region, the 3-million-ha Oregon Coast Range (USA). Gradients in tree species composition were strongly associated with environment, especially climate, and insensitive to disturbance, probably because many dominant tree species are long-lived and persist throughout forest succession. In contrast, forest structure was strongly correlated with disturbance and only weakly with environmental gradients. Although forest structure differed among ownerships, differences were blurred by the presence of legacy trees that originated prior to current forest management regimes. Our multi-ownership perspective revealed biodiversity concerns and benefits not readily visible in single-ownership analyses, and all ownerships contributed to regional biodiversity values. Federal lands provided most of the late-successional and old-growth forest. State lands contained a range of forest ages and structures, including diverse young forest, abundant legacy dead wood, and much of the high-elevation true fir forest. Nonindustrial private lands provided diverse young forest and the greatest abundance of hardwood trees, including almost all of the foothill oak woodlands. Forest industry lands encompassed much early-successional forest, most of the mixed hardwood-conifer forest, and large amounts of legacy down wood. The detailed tree- and species-level data in the maps revealed regional trends that would be masked in traditional coarse-filter assessment. Although abundant, most early-successional forests originated after timber harvest and lacked legacy live and dead trees important as habitat and for other ecological functions. Many large-conifer forests that might be classified as old growth using a generalized forest cover map lacked structural features of old growth such as multilayered canopies or dead wood. Our findings suggest that regional conservation planning include all ownerships and land allocations, as well as fine-scale elements of vegetation composition and structure.

A complex pattern of public and private forest ownership, combined with new regulations for each owner group, raises questions about how well and how efficiently these policies achieve their biodiversity goals. To develop a deeper understanding of the aggregate effect of forest policies, we simulated forest structures, timber production, and socioeconomic conditions over time for the mixture of private and public lands in the 2.3-million-ha Coast Range Physiographic Province of Oregon. To make these projections, we recognized both vegetative complexity at the stand level and spatial complexity at the landscape level. We focused on the two major factors influencing landscape change in the forests of the Coast Range: (1) land use, especially development for houses and cities, and (2) forest management, especially clearcutting. Our simulations of current policy suggest major changes in land use on the margins of the Coast Range, a divergence in forest structure among the different owners, an increase in old-growth forests, and a continuing loss of the structural elements associated with diverse young forests. Our simulations also suggest that current harvest levels can be approximately maintained, with the harvest coming almost entirely from private lands. A policy alternative that retained live trees for wildlife would increase remnant structures but at a cost to landowners (5-7% reduction in timber production). Another alternative that precluded thinning of plantations on federal land would significantly reduce the area of very large diameter (> 75 cm dbh) conifer forests 100 years into the future.

This 2.3-million-ha province is characterized by a diversity of public and private forest owners, and a wide range of forest policy and management objectives. We evaluated habitat availability for seven focal species representing different life histories. We also examined how policies affected old-growth stand structure, age distributions relative to the historical range of variability, and landscape patterns of forest types. Under the current policy scenario, the area of habitat for old-growth forest structure and associated species increased over time, the habitat for some early-successional associates remained stable, and the area of hardwood vegetation and diverse early- successional stages declined. The province is projected to move toward but not reach the historical range of variation of forest age classes that may have occurred under the wild. re regimes of the pre-Euroamerican settlement period. Ownership explained much of the pattern of biodiversity in the province, and under the current policy scenario, its effect increased over time as the landscape diverged into highly contrasting forest structures and ages. Patch type diversity declined slightly overall but declined strongly within ownerships. Most of the modeled change in biodiversity over time resulted from policies on public forest lands that were intended to increase the area of late-successional forests and species. One of the alternative policies, increased retention of wildlife trees on private lands, reduced the contrast between ownerships and increased habitat availability over time for both early- and late-successional species. Analysis of another alternative, stopping thinning of plantations on federal lands, indicated that current thinning regimes improve habitat for the Olive-sided Flycatcher, but the no-thinning alternative had no effect on the habitat scores for the late-successional species in the 100-year simulation. A comparison of indicators of biological diversity suggests that using focal species and forest structural measures can provide complementary information on biodiversity. The multi-ownership perspective provided a more complete synthesis of province-wide biodiversity patterns than assessments based on single ownerships.

As part of the Coastal Landscape Analysis and Modeling Study (CLAMS), we examined how salmon-habitat potential was distributed relative to current and future (+100 years) landscape characteristics in the Coastal Province of Oregon, USA. The intrinsic potential to provide high-quality rearing habitat was modeled for juvenile coho salmon (Oncorhynchus kisutch) and juvenile steelhead (O. mykiss) based on stream flow, valley constraint, and stream gradient. Land ownership, use, and cover were summarized for 100-m analysis buffers on either side of stream reaches with high intrinsic potential and in the overall area encompassing the buffers. Past management seems to have concentrated nonindustrial private ownership, agriculture, and developed uses adjacent to reaches with high intrinsic potential for coho salmon. Thus, of the area in coho salmon buffers, 45% is either non-forested or recently logged, but only 10% is in larger-diameter forests. For the area in steelhead buffers, 21% is either non-forested or recently logged while 20% is in larger-diameter forests. Older forests are most extensive on federal lands but are rare on private lands, highlighting the critical role for public lands in near-term salmon conservation. Agriculture and development are projected to remain focused near high-intrinsic-potential reaches for coho salmon, increasing the importance of effectively addressing nonpoint source pollution from these uses. Percentages of larger-diameter forests are expected to increase throughout the province, but the increase will be only half as much in coho salmon buffers as in steelhead buffers. Most of the increase is projected for public lands, where policies emphasize biodiversity protection. Results suggest that widespread recovery of coho salmon is unlikely unless habitat can be improved in high-intrinsic-potential reaches on private lands. Knowing where high-intrinsic-potential stream reaches occur relative to landscape characteristics can help in evaluating the current and future condition of freshwater habitat, explaining differences between species in population status and risk, and assessing the need for and feasibility of restoration.

TI Regional policy models for forest biodiversity analysis: Lessons from Coastal Oregon SO ECOLOGICAL APPLICATIONS LA English DT Article DE anticipatory assessments; mixed-owner landscapes; political processes; regional ecosystem perspectives; stakeholders ID MANAGEMENT; SCIENCE; SCIENTISTS; NORTHWEST; CONTEXT AB The crisis in the early 1990s over conservation of biodiversity in the forests of the Pacific Northwest caused an upheaval in forest policies for public and private landowners. These events led to the development of the Coastal Landscape Assessment and Modeling Study (CLAMS) for the Coast Range Physiographic Province of Oregon, a province containing over two million hectares of forest with a complex mixture of public and private ownership. Over a decade, CLAMS scientists developed regional data bases and tools to enable assessments of the implications of current policies for biodiversity and have begun using these data and tools to test ideas for solving policy problems. We summarize here four main lessons from our work: (1) Regional ecosystem perspectives, while rewarding, are difficult to achieve. Helping policy makers and the public understand biodiversity policies for an entire province can assist in developing more reasoned policies. However, this result is difficult to achieve because needed scientific building blocks generally do not exist, few policy institutions address regional cross-ownership issues, people can find it difficult to take a regional view, and the appropriate region for analysis changes with the policy problem. (2) Interest in environmental policy analysis may come as much from a pursuit of power as a pursuit of understanding. Biodiversity policy analyses are often viewed as weapons in an ongoing political battle. Also, results that might destabilize existing policies generally will not be well received by those in power. (3) The relationship of regional analyses to civic processes remains challenging and unsettled. Communication between citizens and scientists takes real effort. Also, collaborative processes both inspire and constrain regional policy analysis, and scientific work often proceeds at a different pace than these processes. In the end, CLAMS's most important effect on the civic dialogue may be to change how people think about the Coast Range. (4) An important role exists for anticipatory assessments done independently by scientists. Independent review will be especially important as policy analyses shift to management of nonfederal forests. Our future efforts in CLAMS will focus on evaluating ideas for fundamental changes in forest management. C1 Oregon State Univ, Dept Forest Resources, Corvallis, OR 97331 USA.

Evaluation of climate is fundamental to determining the potential success of an introduced or invasive insect pest. However, evaluating climatic suitability poses substantial difficulties; climate can be measured and assessed in a bewildering array of ways. Some physiological filter, in essence a lens that focuses climate through the requirements and constraints of a potential pest introduction, is required. Difficulties in assessing climate suitability are further exacerbated by the effects of climate change. Gypsy moth (Lymantria dispar L.) is an exotic, tree-defoliating insect that is frequently introduced into the western United States. In spite of an abundance of potential host species, these introductions have yet to result in established populations. The success of eradication efforts and the unsuccessful establishment of many detected and undetected introductions may be related to an inhospitable climate. Climatic suitability for gypsy moth in the western United States, however, is potentially improving, perhaps rapidly, due to a general warming trend that began in the mid 1970s and continues today. In this work, we describe the application of a physiologically based climate suitability model for evaluating risk of gypsy moth establishment on a landscape level. Development of this risk assessment system first required amassing databases that integrated the gypsy moth climatic assessment model, with host species distributions, and climate (historical, present, and future). This integrated system was then used to evaluate climate change scenarios for native host species in Utah, with the result that risk of establishment will dramatically increase during the remainder of the 21st century under reasonable climate change scenarios. We then applied the risk assessment system to several case histories of detected gypsy moth introductions in Utah. These applications demonstrated the general utility of the system for predicting risk of establishment and for designing improved risk detection strategies.

We tested the hypothesis that sediment moisture availability (deficit, excess) as mediated by sediment texture and depth to the prevailing water table is a major factor governing black willow survival during the initial stage of establishment following transplanting. Replicated plots were established across elevational gradients and a range of soil texture. Each plot contained 16 planted cuttings (2.5 cm diameter x 2.5 m length). Plot depth to water table, soil texture, and soil redox potential were measured. Plant gas exchange, leaf chlorophyll content, growth, and survival were monitored periodically over two growing seasons. Survival was best at low elevation compared to cuttings planted at mid- and high elevations. Poor survival and growth were noted for cuttings that encountered sediment moisture deficits in plots with coarse texture while the best cutting survival was recorded for intermediate sand content plots. Results indicated that plot location on the bank and soil texture are two important factors that influence riverbank restoration success. Therefore, any riparian restoration plan should include careful assessment of these factors prior to undertaking such efforts. (c) 2006 Elsevier B.V All rights reserved.

Similarly, the spread of established invaders into new habitats can be influenced by the degree to which small founder populations ahead of the invasion front are suppressed through Allee effects. We develop an approach to use empirical data on the gypsy moth, a non-indigenous invader in North America, to quantify the Allee threshold across geographical regions, and we report that the strength of the Allee effect is subject to spatial and temporal variability. Moreover, we present what is to our knowledge the first empirical evidence that geographical regions with higher Allee thresholds are associated with slower speeds of invasion.

We reconstructed a history of low-severity fires (1750-1950) near the northern limit of ponderosa pine and demonstrated that local-scale spatial variation in fire frequency varied with topography and that the intra-ring position of fire scars (a proxy for fire seasonality) varied somewhat with topography but more strongly by tree species. Fires were significantly more frequent on the south than the north aspect (14 versus 24 y mean plot fire intervals, respectively), likely due to differences in fuel type and condition. Frequency did not vary with elevation, although our range of elevation is likely too narrow to detect such variation (227 in). Ring-boundary scars were 5.6 times more likely on Douglas-fir than ponderosa pine, 1.8 times more likely on north than south aspects, and 1.6 times more likely at low than high elevation. Our results confirm the importance of understanding the effect of interspecific variation and topography on cambial phenology and hence intra-ring position before inferring historical fire seasonality from fire scars.

In a first application of non-metric multidimensional scaling to a large-scale, framework dataset, we modeled lichen community response to air quality and climate gradients at 1416 forested 0.4 ha plots. Model development balanced polluted plots across elevation, forest type and precipitation ranges to isolate pollution response. Air and climate scores were fitted for remaining plots, classed by lichen bioeffects, and mapped. Projected 2040 temperatures would create climate zones with no current analogue. Worst air scores occurred in urban-industrial and agricultural valleys and represented 24% of the landscape. They were correlated with: absence of sensitive lichens, enhancement of nitrophilous lichens, mean wet deposition of ammonium > 0.06 mg l(-1), lichen nitrogen and sulfur concentrations > 0.6% and 0.07%, and SO(2) levels harmful to sensitive lichens. The model can detect changes in air quality and climate by scoring re-measurements. (c) 2006 Elsevier Ltd. All rights reserved.

TI Physical effects of weather events on the abundance and diversity of insects in North American forests SO ENVIRONMENTAL REVIEWS LA English DT Review DE Dendroctonus; disturbances; flooding; forest insects; ice storms; weather events; wind storms ID DOUGLAS-FIR BEETLE; SUB-ALPINE FOREST; ICE STORM DAMAGE; SPRUCE BUDWORM LEPIDOPTERA; TORTRICIDAE MOTH FLIGHT; SOUTHERN-BOREAL FOREST; GREAT-LAKES REGION; OAK-HICKORY FOREST; IPS-PINI SAY; BARK BEETLES AB We summarize the effects of major weather events such as ice storms, wind storms, and flooding on the abundance and diversity of terrestrial forest insects and their allies. This synthesis indicates that weather events influence both spatial and temporal patterns of forests and insect communities in North American landscapes: The Atlantic and Pacific oceanic sides of the continent are relatively more susceptible to ice and wind storms, respectively. There have been more studies and reports on the responses of forest insects to wind storms, and on economically important subcortical insects than on gall-forming, foliage-feeding; fungal-feeding, litter-dwelling, pollinating, parasitizing, predaceous, root-feeding, and sap-feeding insects. Weather events positively affect populations of subcortical insect species, and impact their colonization patterns and dynamics. Species belonging to genera such as Dendroctonus (Scolytidae) and Monochamus (Cerambycidae) may sometimes cause economic damage by colonizing residual live tree, and dead trees, rendering the wood unsalvageable. Subsequent outbreaks of spruce beetle, Dendroctonus rufipennis (Kirby) and Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, have been frequently documented in western North American forests following wind events. Wind disturbances have also been observed to accelerate the life-cycles of D. rufipennis and Semanotus litigiosus (Casey) (Cerambycidae), and in rare instances, have caused Monochamus spp. to become primary colonizers. Populations of other important subcortical species have not always increased dramatically following weather events. Foliage- and pollen-feeding insects may experience mortality directly from a weather event or indirectly through habitat alteration. In some cases, forest insects may use storms to migrate to new habitats. Populations of open-habitat and forest specialist litter-dwelling species have increased and decreased, respectively, subsequent to weather events. Forest specialist species generally rebound within a short period of time, suggesting that they are adapted to these periodic weather events. Little is known about the combined effects of post-weather-disturbance management practices such as salvage-logging and prescribed-burning on insects in North American forests. C1 [Gandhi, Kamal J.

Evaluating complex technical data and developing feasible risk management options requires procedural flexibility that may not be part of existing evaluative structures. Experience has demonstrated that direct transposition of risk assessment and risk management frameworks (e.g. those developed in the United States and European Union) may not work in regions whose social, legal, historical, political and economic situations are not suitable or prepared for acceptance of these methodologies. Flexible decision-making including the use and development of acceptable or unacceptable risk levels based on the critical nature of an infrastructure type, is one potential approach to assist risk managers in their decision-making. Unfortunately, the newness of the discussions on the interrelatedness of environmental security and critical infrastructure has yet to produce a unified and comprehensive treatment of the fields. As a result, this paper will describe and define these terms in order to set the stage for discussions of human health and ecological risk assessment and risk management later in the paper. This paper reviews basic concepts defined in the field of risk assessment and extends its applicability to the areas of environmental security and critical infrastructure protection. C1 [Belluck, D.

CA Emerging Infections Program FoodNe TI Re-assessment of risk factors for sporadic Salmonella serotype enteritidis infections: a case-control study in five FoodNet sites, 2002-2003 SO EPIDEMIOLOGY AND INFECTION LA English DT Article ID UNITED-STATES; SURVEILLANCE; OUTBREAK; CONSUMPTION; CHILDREN; ILLNESS; DISEASE; BURDEN AB Active surveillance for laboratory-confirmed Salmonella serotype Enteritidis (SE) infection revealed a decline in incidence in the 1990s, followed by an increase starting in 2000. We sought to determine if the fluctuation in SE incidence could be explained by changes in foodborne sources of infection. We conducted a population-based case-control study of sporadic SE infection in five of the Foodborne Diseases Active Surveillance Network (FoodNet) sites during a 12-month period in 2002-2003. A total of 218 cases and 742 controls were enrolled. Sixty-seven (31%) of the 218 case-patients and six (1%) of the 742 controls reported travel outside the United States during the 5 days before the case's illness onset (OR 53, 95% CI 23-125). Eighty-one percent of cases with SE phage type 4 travelled internationally. Among persons who did not travel internationally, eating chicken prepared outside the home and undercooked eggs inside the home were associated with SE infections. Contact with birds and reptiles was also associated with SE infections. This study supports the findings of previous case-control studies and identifies risk factors associated with specific phage types and molecular subtypes.

TI Differentiating greenbug resistance genes in barley SO EUPHYTICA LA English DT Article DE resistance genes; barley; greenbug; Schizaphis graminum; biotypes ID HOMOPTERA; APHIDIDAE; BIOTYPES AB The greenbug [Schizaphis graminum (Rondani)] is an extremely damaging pest of barley (Hordeum vulgare L), particularly in the southern Great Plains of the USA. Two greenbug resistance genes, Rsg1a (in 'Post 90') and Rsg2b (in PI 426756), available for developing resistant barley cultivars, have similar phenotypes when challenged by various greenbug biotypes. This study was conducted to separate these two resistance genes via differential plant reactions to a recently collected field isolate of greenbug. Four barley entries and one wheat germplasm were challenged with two greenbug isolates and damage ratings were recorded for each combination. One greenbug isolate used in this study (TX1) was able to differentiate Rsg1a from Rsg2b through dramatically different plant responses (Rsg2b conferred resistance, Rsg1a did not). The results indicate the potential vulnerability of greenbug resistance genes in barley. Based on these and other reported results, we propose that gene symbol designations for greenbug resistance in barley be changed from Rsg1a to Rsg1 and Rsg2b to Rsg2.

ANNUA; TRAIT; POLYMORPHISM; ASSOCIATION; POPULATIONS AB Flowering dates and life forms of all available Brassica napus accessions conserved at the North Central Regional Plant Introduction Station (NCRPIS) were characterized, and a survey of molecular variation was conducted by using simple sequence repeats (SSR) in order to support better management of accessions with diverse life forms. To characterize flowering phenology, 598 B. napus accessions from the NCRPIS collection were planted in Iowa and Kansas field sites together with a current commercial cultivar and observed for days to flowering (first, 50% and 100% flowering) in 2003. Days from planting to 50% flowering ranged from 34 to 83 in Iowa and from 53 to 89 in Kansas. The mean accumulated growing degree days (GDD) to 50% flowering were 1,997 in Iowa, and 2,106 in Kansas. Between locations, the correlation in flowering time (r = 0.42) and the correlation in computed GDD (r = 0.40) were both significant. Differences in flowering-time rank were observed for several accessions. Accessions that failed to flower in Iowa in a single growing season comprised 28.5% of the accessions; of the flowering accessions, 100% plant flowering was not always achieved. Accessions were grouped according to flowering time. A stratified sample of 50 accessions was selected from these groups, including 10 non-flowering and 40 flowering accessions of diverse geographic origins and phenological variation. The flowering time observed in the sampled accessions when grown in the greenhouse were found to be significantly correlated to the flowering time observed in the field locations in Iowa (r = 0.79) and Kansas (r = 0.49). Thirty SSR markers, selected across 18 Brassica linkage groups from BrassicaDB, and 3 derived from Brassica expressed sequence tags (ESTs) were scored in the stratified sample. An average of three bands per SSR primer pair was observed. Associations of SSR marker fragments with the life forms were determined. Analysis of molecular variation by using cluster analysis and ordination resulted in recognizable, distinct groups of annual and biennial life-form types, which may have direct applications for planning and management of future seed regenerations.

We crossed four photoperiod-sensitive accessions of cotton, G. hirsutum L., with a cultivar, selected day-neutral plants and backcrossed four times to each of the four photoperiod-sensitive accessions, selecting day-neutral plants at each generation. The day-neutral plants from the first cross and the four backcross generations were advanced to the F-6. These 20 day-neutral lines and four cultivars were grown in two environments at Mississippi State, MS and scored for seven agronomic and fiber quality traits. They were also scored for AFLP markers using a bulk sample of leaves from each of 24 lines. More than 50 AFLP markers were associated with the seven traits with fewer markers associated with fiber than agronomic traits. However, one to four markers were associated with 22-93% of the phenotypic variability of each of the seven traits. The results suggest that selected markers could be used in marker assisted selection (MAS) in crosses designed to use alleles from exotic accessions or cultivars to develop elite breeding lines for cotton improvement.

TI Evaluation of partially hydrogenated methyl esters of soybean oil as biodiesel SO EUROPEAN JOURNAL OF LIPID SCIENCE AND TECHNOLOGY LA English DT Article DE biodiesel; low-temperature performance; lubricity; oxidative stability; partial hydrogenation ID LOW-TEMPERATURE PROPERTIES; OXIDATIVE STABILITY; VEGETABLE-OILS; ALKYL ESTERS; INDEX; FUEL; DEPENDENCE; ENGINE AB Biodiesel, an alternative fuel derived from vegetable oils or animal fats, continues to undergo rapid worldwide growth. Specifications mandating biodiesel quality, most notably in Europe (EN 14214) and the USA (ASTM D6751), have emerged that limit feedstock choice in the production of biodiesel fuel. For instance, EN 14214 contains a specification for iodinevalue (IV; 120g I(2)/100g maximum) that eliminates soybean oil as a potential feedstock, as it generally has an IV > 120. Therefore, partially hydrogenated soybean oil methyl esters (PHSME; IV = 116) were evaluated as biodiesel by measuring a number of fuel properties, such as oxidative stability, low-temperature performance, lubricity, kinematic viscosity, and specific gravity. Compared to soybean oil methyl esters (SME), PHSME were found to have superior oxidative stability, similar specific gravity, but inferior low-temperature performance, kinematic viscosity, and lubricity. The kinematic viscosity and lubricity of PHSME, however, were within the prescribed US and European limits. There is no universal value for low-temperature performance in biodiesel specifications, but PHSME have superior cold flow behavior when compared to other alternative feedstock fuels, such as palm oil, tallow and grease methyl esters. The production of PHSME from refined soybean oil would increase biodiesel production costs by US$ 0.04/L (US$ 0.15/gal) in comparison to SME. In summary, PHSME are within both the European and American standards for all properties measured in this study and deserve consideration as a potential biodiesel fuel.

Therefore, it is timely to recall the exciting, steadily growing, yet underappreciated body of evidence that subcutaneous adipocytes are so much more than just 'fat guys', hanging around passively to conspire, at most, against your desperate attempts to maintain ideal weight. Although the subcutis, quantitatively, tends to represent the dominant architectural component of human skin, conventional wisdom confines its biological key functions to those of energy storage, physical buffer, thermoregulation and thermoinsulation. However, already the distribution of human superficial adipose tissue, by itself, questions how justified the popular belief is that 'skin fat' (which actually may be more diverse than often assumed) serves primarily thermoinsulatory purposes. And although the metabolic complications of obesity are well appreciated, our understanding of how exactly subcutaneous adipocytes contribute to extracutaneous disease - and even influence important immune and brain functions! - is far from complete. The increasing insights recently won into subcutaneous adipose tissue as a cytokine depot that regulates innate immunity and cell growth exemplarily serve to illustrate the vast open research expanses that remain to be fully explored in the subcutis. The following public debate carries you from the evolutionary origins and the key functional purposes of adipose tissue, via adipose-derived stem cells and adipokines straight to the neuroendocrine, immunomodulatory and central nervous effects of signals that originate in the subcutis - perhaps, the most underestimated tissue of the human body. The editors are confident that, at the end, you shah agree: No basic scientist and no doctor with a serious interest in skin, and hardly anyone else in the life sciences, can afford to ignore the subcutaneous adipocyte - beyond its ample impact on beauty, benessence and body mass.

The genus Stephanoascus is polyphyletic, resulting in reassignment of two species to the older genus Trichomonascus and the third to Sugiyamaella gen. nov. (type species Sugiyamaella smithiae). The genera Sporopachydermia, Wickerhamiella and Zygoascus appear to be monophyletic. The species Pichia ofunaensis and P. tannicola are proposed for transfer to Zygoascus. Arxula, Blastobotrys and Sympodiomyces are members of the Trichomonascus clade, with the genus Blastobotrys having taxonomic priority for anamorphic states. Trigonopsis variabilis and three species of Candida represent a distinct clade. From the foregoing gene sequence analyses, the new ascosporic genus Sugiyamaella is proposed, as are 14 new species combinations and the new family Trichomonascaceae.

Clinical surveillance is the basis for early detection of disease and is usually centered on the detection of syndromes and clinical findings requiring confirmation by diagnostic laboratories. Although most of the tests applied usually perform to an acceptable standard, several have not been properly validated in terms of their diagnostic sensitivity and specificity. Sensitivity and specificity estimates can vary according to local conditions and, ideally, should be determined by national laboratories where the tests are to be applied. The importance of sensitivity and specificity estimates in the design and interpretation of statistically based surveys and risk analysis is fundamental to establish appropriate disease control and prevention strategies. The World Organisation for Animal Health's (OIE) network of reference laboratories acts as centers of expertise for the diagnosis of OIE listed diseases and have a role in promoting the validation of OIE prescribed tests for international trade. This paper discusses the importance of the epidemiological evaluation of diagnostic tests and the role of the OIE Reference Laboratories and Collaborating Centres in this process.

Lactose and citrate are metabolized by lactic acid bacteria to form a number of important compounds, including acetoin, 2,3-butanediol, and diacetyl, which generate buttery, cheesy flavors. Proteolysis of casein by coagulant, plasmin, and other enzymes leads to the production of acids, alcohols, aldehydes, amines, and amino acids, which bring about alcoholic, fatty, and green flavor notes. The breakdown of aromatic, branched-chain, and sulfur-containing amino acids also produces flavor compounds, many of which are undesirable. Triacylglycerols are lipolyzed into fatty acids, which impart pungent, cheesy flavors. Fatty acids can then be converted into methyl ketones, secondary alcohols, lactones, esters, and other compounds, which are responsible for earthy, floral, fruity, and rancid flavors. An array of compounds contributes to the unique flavor characteristics of each cheese variety.

TI Synthesis and evaluation of molecularly imprinted polymers as sorbents of moniliformin SO FOOD ADDITIVES AND CONTAMINANTS LA English DT Article DE moniliformin; molecularly imprinted polymers; molecular recognition; mycotoxins ID PERFORMANCE LIQUID-CHROMATOGRAPHY; SOLID-PHASE EXTRACTION; OCHRATOXIN-A; MYCOTOXIN MONILIFORMIN; RECOGNITION PROPERTIES; COMPUTATIONAL APPROACH; MASS-SPECTROMETRY; ZEARALENONE; BINDING; RESONANCE AB Moniliformin is a low molecular weight mycotoxin that has worldwide potential to contaminate cereal grains. Although several traditional methods have been developed to detect moniliformin, the lack of anti-moniliformin antibodies has created a need for materials that recognize moniliformin at the molecular level through a binding mechanism. To address this issue, the authors synthesized molecularly imprinted polymers that bind moniliformin. Imprinted and non-imprinted polymers were evaluated by equilibrium binding assays and moniliformin concentrations were measured by LC analysis using ultraviolet light detection. Successful polymers were imprinted with toxin analogues as the templates; non-imprinted polymers exhibited minimal binding in acetonitrile under the assay conditions. Selected imprinted polymers also bound moniliformin in ethanol, methanol and dimethyl formamide. Significant differences in moniliformin binding by the polymers were dependent on polymer composition, and these differences were highly dependent on the template used to imprint the polymer. Polymers were further evaluated as sorbents for molecularly imprinted solid-phase extraction (MISPE), and an imprinted polymer was used for preconcentration and clean-up of a moniliformin spiked corn extract.

The biosynthesis of aflatoxins is modulated by many environmental factors, including the availability of a carbon source. The gene expression profile of A. parasiticus was evaluated during a shift from a medium with low concentration of simple sugars, yeast extract (YE), to a similar medium with sucrose, yeast extract sucrose (YES). Gene expression and aflatoxins (B-1, B-2, G(1), and G(2)) were quantified from fungal mycelia harvested pre-and post-shifting. When compared with YE media, YES caused temporary reduction of the aflatoxin levels detected at 3-h post-shifting and they remained low well past 12 h post-shift. Aflatoxin levels did not exceed the levels in YE until 24 h post-shift, at which time point a tenfold increase was observed over YE. Microarray analysis comparing the RNA samples from the 48-h YE culture to the YES samples identified a total of 2120 genes that were expressed across all experiments, including most of the aflatoxin biosynthesis genes. One-way analysis of variance (ANOVA) identified 56 genes that were expressed with significant variation across all time points. Three genes responsible for converting norsolorinic acid to averantin were identified among these significantly expressed genes. The potential involvement of these genes in the regulation of aflatoxin biosynthesis is discussed. C1 Mississippi State Univ, Dept Biochem & Mol Biol, Mississippi State, MS 39762 USA.

TI Analysis of aflatoxin regulatory factors in serial transfer-induced non-aflatoxigenic Aspergillus parasiticus SO FOOD ADDITIVES AND CONTAMINANTS LA English DT Article; Proceedings Paper CT International Conference on Advances in Genomics, Biodiversity and Rapid Systems for Detection of Toxigenic Fungi and Mycotoxins CY SEP 26-29, 2006 CL Monopoli, ITALY SP Mycoglobe DE mycology; mycotoxins ID SECONDARY METABOLITE PRODUCTION; MOLECULAR CHARACTERIZATION; MORPHOLOGICAL VARIANTS; TRANSCRIPTION FACTOR; SIGNALING PATHWAY; GENETIC-ANALYSIS; BIOSYNTHESIS; AFLR; NIDULANS; PROTEIN AB Aflatoxins (AFs) are carcinogenic secondary metabolites of Aspergillus parasiticus. In previous studies, non- toxigenic A. parasiticus sec - ( for secondary metabolism negative) variants were generated through serial transfer of mycelia from their toxigenic sec+ ( for secondary metabolism positive) parents for genetic and physiological analysis for understanding regulation of AF biosynthesis. Previous studies have shown no difference in the DNA sequence of aflR, a positive regulator of AF production, in the sec+ and sec - strains. In this study, AflJ, another positive regulator of AF production, laeA, a global regulator of secondary metabolism, and the intergenic region between aflR and aflJ, were analysed to determine if they play a role in establishment of the sec - phenotype. The study showed that while this sequence identity extended to the aflJ as well as the aflJ - aflR intergenic region, expression of aflR in the sec - strain was several fold lower than that observed in the sec+ strain, while aflJ expression was barely detectable in the sec - strain. Western blot analysis indicated that despite AflR protein being present in the sec - strain, no toxin production resulted. Introduction of a second copy of aflR into the sec - strain increased aflR expression, but did not restore AF production. Lastly, reverse transcription- PCR analysis revealed that laeA was expressed in both sec+ and sec - strains. These results suggest that although aflR, aflJ and laeA are necessary for AF production, they are not sufficient. We propose that the aflR and aflJ expression may be regulated by element( s) downstream from laeA or from pathways not influenced by laeA. C1 Xavier Univ, Dept Biol, New Orleans, LA 70125 USA.

The fungal genus Fusarium includes agronomically important plant pathogenic and mycotoxin- producing species and produces numerous polyketides. The study further characterized a polyketide synthase- encoding gene ( PKS3 = PGL1) that was previously identified in F. graminearum and F. verticillioides. Disruption of the F. verticillioides PGL1 indicated that it is required for the production of the dark pigment in perithecial walls, as previously shown in F. graminearum. A third PGL1 orthologue was identified in the genomic sequence of N. haematococca ( anamorph F. solani f. sp. pisi). Analysis of the carboxy- terminal end of the deduced PGL1 protein indicated that it had a functional domain related to dehydrogenases/reductases that is sometimes present in non- ribosomal peptide synthetases. Comparison of the genomic regions flanking PGL1 in F. graminearum, F. verticillioides and N. haematococca revealed that the extent of gene synteny in this region was greater between F. graminearum and F. verticillioides than between either of these species and N. haematococca. Southern blot analysis indicated that PGL1 occurs widely within the genus Fusarium including species with no known sexual stage. C1 USDA, Natl Ctr Agr Utilizat Res, Agr Res Serv, Peoria, IL USA.

Studies assessed A. flavus propagules, Fusarium spp., and total fungi associated with Mississippi Delta soils. Soils from 12 and 15 sites were collected in 2000 and 2001, respectively. The propagule density of A. flavus ranged from log( 10) 2.0 to 4.3 colony-forming units (cfu) g(-1) soil, while total fusaria ranged from log(10) 3.0 to 5.4 cfu g(-1) soil. The highest populations of A. flavus were associated with soils containing higher organic matter, especially in sites under a no- tillage management. The frequency of aflatoxin production in isolates ranged from 13 to 81% depending on soil. In 2001, there was a highly significant correlation between A. flavus and the history of maize cultivation. Soil fertility factors such as organic matter content, nitrate and extractable phosphorus correlated with the density of Aspergillus, Fusarium spp., and total fungi. The relationship between soil parameters and Aspergillus populations may be useful in predicting the contribution of soil microflora to aflatoxin contamination.

The primary objective of this study was to determine whether nine F. proliferatum strains from wheat from Nepal can cause black point and fumonisin contamination in wheat kernels. For comparison, the study included three Fusarium strains from US maize. In test 1, all the strains but one produced significant symptoms of kernel black point; two strains decreased kernel yield; and four strains contaminated kernels with fumonisins B-1, B-2 and B-3 as determined by liquid chromatography- mass spectroscopy. Strain Ggm202 from Nepal, which produced the highest levels of fumonisins (mean = 49 mu gg(-1)) on five wheat cultivars in test 1, was confirmed to produce fumonisins ( mean = 38 mu gg(-1)) on two cultivars in test 2.

There were four rotation systems (continuous cotton, continuous corn, cotton - corn and corn - cotton) for both glyphosate-resistant (GR) and non-GR cultivars-herbicide system arranged in a randomized complete block design with four replications. Aspergillus flavus populations in surface (5-cm depth) soil, sampled before planting (March/April), mid-season (June) and after harvest (September), ranged from 1.47 to 2.99 log (10) cfu g(-1) soil in the four rotation systems. Propagules of A. flavus were higher in the continuous corn system compared to the continuous cotton system on three sample dates, and cotton rotated with corn decreased A. flavus propagules in three of nine sample dates. Propagules of A. flavus were significantly greater in plots with GR cultivars compared to non-GR cultivars in three samples. In cotton seed, aflatoxin and fumonisin levels were similar (<= 4 mu g kg(-1) and non-detectable, respectively) regardless of rotation and glyphosate. In corn grain, aflatoxin was above the regulatory level (>= 20 mu g kg(-1)) only in GR cultivar in 2004 and 2005. Fumonisin was higher in non-GR cultivar (4 mu g kg(-1)) regardless of rotation in 2004; however, in 2002, 2003 and 2005, aflatoxin and fumonisin levels were similar regardless of rotation and glyphosate. These results indicate the potential for increased aflatoxin and fumonisin levels (1 of 4 years) in corn; however, climatic conditions encountered during this study did not allow for mycotoxin production. In laboratory incubation studies, fairly high concentrations of glyphosate were required to inhibit A. flavus growth; however no short-term effect of soil treatment with glyphosate on A. flavus populations were observed. These data suggest that altered populations of A. flavus or higher aflatoxin concentrations in corn grain were due to indirect effects of the GR cropping system. C1 [Abbas, H.

Many internal and external factors, such as nutrition and environment affect aflatoxin biosynthesis; therefore, we analyzed the transcriptome of A. flavus using expressed sequence tags ( ESTs) from a normalized cDNA expression library constructed from mycelia harvested under several conditions. A total of 7218 unique ESTs were identified from 26 110 sequenced cDNA clones. Functional classifications were assigned to these ESTs and genes, potentially involved in the aflatoxin contamination process, were identified. Based on this EST sequence information, a genomic DNA amplicon microarray was constructed at The Institute for Genomic Research ( TIGR). To identify potential regulatory networks controlling aflatoxin contamination in food and feeds, gene expression profiles in aflatoxinsupportive media versus non- aflatoxin- supportive media were evaluated in A. flavus and A. parasiticus. Genes consistently expressed in several aflatoxin- supportive media are reported. C1 USDA ARS, So Reg Res Ctr, New Orleans, LA 70124 USA. Inst Genom Res, Rockville, MD 20850 USA.

Development of control strategies against A. flavus and A. parasiticus, the major aflatoxin- producing species, is dependent upon a basic understanding of their diversity in agricultural ecosystems. This review summarizes our current knowledge of species and population diversity in the United States in relation to morphology, mycotoxin production and genetic characters. The high genetic diversity in populations of aflatoxigenic fungi is a reflection of their versatile habits in nature, which include saprotrophic colonization of plant debris in soil and parasitism of seeds and grain. Genetic variation within populations may originate from a cryptic sexual state. The advent of intensive monoculture agriculture not only increases population size but also may introduce positive selective pressure for aflatoxin production due to its link with pathogenicity in crops. Important goals in population research are to determine how section Flavi diversity in agricultural ecosystems is changing and to measure the direction of this evolution.

TI Flax seed oil and flax seed meal reduce the formation of aberrant crypt foci (ACF) in azoxymethane-induced colon cancer in Fisher 344 male rats SO FOOD AND CHEMICAL TOXICOLOGY LA English DT Article DE flax seed meal; flax seed oil; azoxymethane; aberrant crypt foci ID GLUTATHIONE TRANSFERASES; EXPERIMENTAL METASTASIS; MELANOMA-CELLS; TREATED RATS; FATTY-ACIDS; DIET; SUPPLEMENTATION; PREVENTION; CARCINOGENESIS; NUTRITION AB Flax seed oil and flax seed meal are good sources of omega-3 fatty acids. The objective of this study was to explicate the effects of feeding flax seed oil and flax seed meal on AOM-induced aberrant crypt foci (ACF) in Fisher 344 male rats. Following an acclimatization period, rats were divided into six groups and fed AIN 93G diet Control (C), C + 7 and 14% soybean oil (SBO), C + 7 and 14% flax seed oil (FSO) and C + 10 and 20% flax seed meal (FSM). All rats received 16 mg/kg body weight of AOM at 7 and 8 weeks of age. The rats were euthanized with CO2 at 17 weeks of age. FSM and FSO reduced the incidence of ACF which are putative precursor lesions in the development of colon cancer in the distal colon by 88% and 77%, in the proximal colon by 86% and 87%, with a total reduction of 87.5% and 84%, respectively. Glutathione-S-transferase (GST) activities were significantly (P < 0.05) higher in rats fed C + 7 and 14% FSO and C + 10 and 20% FSM, as compared to rats fed C + SBO diets. Results of this study showed that FSO and FSM reduced the incidence of AOM-induced ACF formation and may therefore be effective chemopreventive agents. (c) 2006 Elsevier Ltd. All rights reserved.

The samples examined were from four mono-varietal wines (12 Cabernet Sauvignon, 9 Merlot, 7 Riesling, 14 Chardonnay). Wine samples represented twelve wineries that obtain their fruit from vineyards located within Idaho's Snake River Valley. Titratable acidity, pH, specific gravity, colour measurements (lightness, chroma, and hue), % haze, total antbocyanins, total phenolics, total tannins, antioxidant capacity, and individual stilbene measurements were performed. The antioxidant capacities (ORAC values) of Idaho wines ranged from 3.1 (Merlot wine) to 87.0 (Cabernet Sauvignon wine) mu mol of Trolox/ml (mean = 38.5 mu mol of Trolox/ml). Mean ORAC values of Merlot wines (mean = 27.6 mu mol of Trolox/ml) were lower than the other three styles (mean for Cabernet Sauvignon wines = 41.0 mu mol of Trolox/ml, mean for Chardonnay wines = 42.8 mu mol of Trolox/ml, and mean for Riesling wines = 39.4 mu mol of Trolox/ml). Free stilbene levels (four different stilbenes) were examined by direct-HPLC/DAD/ESI-MS/MS method. Piceid and resveratrol (both trans- and cis-) were found in the samples. Stilbene levels ranged from 0.97 (Riesling wine) to 12.88 (Cabernet Sauvignon wine) mg (expressed as trans-resveratrol)l/l.

This systematic study was undertaken to address substantial variations in the solvents and procedures used for the extraction of isoflavones from soybeans by different research groups as described in the recent peer-reviewed published literature. Comparison of four previously optimized and commonly deployed solvent mixtures (acetonitrile: water 58:42 (v/v); ethanol:water 70:30 (v/v); methanol:water 90:10 (v/v); superheated pressurized water) was carried out for the extraction of isoflavones. In addition, we also examined the extraction efficiencies of three additional new solvent mixtures (dimethyl sulphoxide: acetonitrile: water, 5:58:37 (v/v/v); dimethyl sulphoxide: ethanol: water, 5:70:25 (v/v/v); Genapol:water 5:95 (v/v)) for the extraction of isoflavones from soybeans. Assessments of six commonly used extraction techniques (shaking, vortexing, sonication, stirring, Soxhlet, and pressurized liquid extraction (PLE)) with an optimized extraction solvent mixture was also performed. Both, the total isoflavones content and the isoflavones HPLC profile varied significantly with different extraction solvents and techniques. Optimum total isoflavones recoveries from soybean samples were obtained with dimethyl sulphoxide: ethanol: water (5:75:25, v/v/v) solvent mixture using a PLE. Intermediate extraction recoveries of total isoflavones from soybean samples were obtained with the other extraction solvent mixtures and techniques tested. The extraction efficiencies of isoflavones with shaker, vortex, stirring, and Soxhlet were between 65% and 70% as compared to PLE. Total isoflavones extracted by the sonication procedure was 93.3% as compared to PLE. Published by Elsevier Ltd.

One anthocyanin and thirteen glycosylated flavonols were detected in a methanol-water extract. Among them, the 3-O-galactoside, 3-O-glucoside, 3-O-rhamnoside, 3-O-xylopyranoside, 3-O-arabinopyranoside and 3-O-arabinofurano side of quercetin and myricetin, as well as kaempferol 3-O-glucoside were identified by direct comparison with standards or positively identified flavonoids in cranberry. The anthocyanin was the 3-O-hexoside of methyl-cyanidin. Trace amounts of delphinidin and rhamnetin were detected in the hydrolyzed extract, suggesting their glycosides were present, but undetectable, in the original extract. The concentrations of the 14 flavonoids in the tested sample were determined. This is the first report of these flavonoids in cashew apple. Published by Elsevier Ltd.

Reflectance spectra (400-2498 nm) of homogenized meals were obtained with a dispersive NIR spectrometer. Protein and moisture were measured by AOAC reference methods, total fat by a semi-automated acid hydrolysis, solvent extraction, gravimetric method and total carbohydrate calculated. Energy was calculated using Atwater factors. Using multivariate analysis software, PLS models (n = 113-115 products) were developed to relate NIR spectra of homogenized meals to the corresponding reference values. The models predicted components and energy in validation samples (n = 37-38 products), overall, with r(2) of above 0.96. Ratios of deviation to performance were between 3.6 and 6.6, and indicated adequacy of the models for screening, quality control, or process control. Performance of the models varied substantially when used to predict sub-groups of meals within the validation set. Published by Elsevier Ltd. C1 USDA, Agr Res Serv, Athens, GA 30604 USA.

This investigation was conducted to determine the efficacy of SC as a browning control agent for use on fresh-cut apple slices, applied alone, or in conjunction with organic acids. Additionally, the authors compared the efficacy of SC to that of acidified sodium chlorite (ASC) and to several other salts and examined the effect of pH and several different organic acids on efficacy of SC. The fresh-cut apple slices were dipped in treatment solutions for I min, then drained and placed in plastic containers at 20 degrees C for 24 h, and finally stored in polyethylene bags at 5 degrees C for 2 weeks. Color was measured periodically during storage. Lightness (L) values for all treated and control samples measured at 4 h, 24 h, and 2 weeks of storage were compared to L value for untreated samples measured immediately after cutting. Percent decrease in L-values was calculated for each sample at each time interval. Apple slices treated in ASC or SC solution had a significantly smaller decrease in L value indicating less browning than those treated in citric acid or water control at 4 h (P < 0.01), and with the exception of 1 g L-1 ASC and 0.1 g L-1 SC, all other ASC and SC treated slices still had significantly less browning than those for the water control (P < 0.01) at 24 h. After 2 weeks of storage, only SC (0.5-1.0 g L-1), sodium bisulfite (0.5 g L-1) and calcium L-ascorbate (10 g L-1) continued to inhibit browning. Treatment with 0.5 g L-1 SC and pH adjusted in the range from 3.9 to 6.2 using citric acid (CA) reduced browning more effectively than 0.5 g L-1 SC without pH adjustment. Two organic acids, salicylic acid and cinnamic acid, when added to SC solution, were found to achieve even better inhibition of browning than CA at the same pH value. (C) 2007 Elsevier Ltd.

Six treatments and two blank incubations were conducted, testing various fresh raw vegetables on an equal dry matter basis. Considering cholestyramine (bile acid-binding, cholesterol-lowering drug) as 100% bound, the relative in vitro bile acid binding on dry matter (DM) and total dietary fibre (TDF) basis was 1-16% and 2-54%, respectively. Bile acid binding for okra was significantly higher than for all the other vegetables tested. For beets, binding values were significantly higher than for asparagus. Binding values for asparagus were significantly higher than for eggplant, turnips, beans green, carrots and cauliflower. These results point to the health promoting potential of okra > beets > asparagus > eggplant = turnips = green beans = carrots = cauliflower, as indicated by their bile acid binding, on a dry matter basis.

Total phenolics were measured using the Folin-Ciocalteau method, total anthocyanins by the pH-differential method, and -carotene by HPLC. The total antioxidant activity (hydrophilic + lipophilic ORAC) was highest (27.2 mu mol TE/g fresh weight (fw)) for NC415 (purple-fleshed) and lowest (2.72 mu mol TE/g fw) for Xushu 18 (white-fleshed). The hydrophilic-ORAC values were significantly correlated with the DPPH (R(2) = 0.859) and ABTS (R(2) = 0.761) values. However, the lipophilic-ORAC values were poorly correlated with the beta-carotene contents (R(2) = 0.480). The total phenolic contents (0.011-0.949mg chlorogenic acid equivalent/g fw) were highly correlated with the hydrophilic-ORAC (R(2) = 0.937) and DPPH (R(2) = 0.820) values. Therefore, the total phenolic content can serve as a useful indicator for the antioxidant activities of sweet potatoes. (c) 2006 Elsevier Ltd. All rights reserved.

The micro-structural heterogeneity and micro-rheology of high-viscosity oat beta-glucan solutions were investigated by monitoring the thermally driven displacements of well-dispersed microspheres via video fluorescence microscopy. By comparing the distribution of the time-dependent mean-square displacement (MSD) and ensemble-averaged MSD of polystyrene microspheres imbedded in four concentrations of beta-glucan solutions, we found that the solutions exhibited perfectly homogeneous behaviour at <= 1%, but showed a certain degree of heterogeneity at 2%. Micro-rheology investigation revealed that beta-glucan solutions displayed nearly perfect viscous behaviour at <= 1%, but the property changed into viscoelastic at 2%. Both micro-structural heterogeneity and micro-rheological property shifts occurred over a small concentration range, between 1% and 2%, of beta-glucan. Published by Elsevier Ltd.

Whole fruit, previously held at 4 degrees Q was immersed in heated water (60 degrees C) with and without dissolved calcium lactate (1%). Fresh-cut processing was done immediately, either after treatment or after storage at 4 degrees C for 24 h. Headspace gas accumulation during storage indicated reduced respiration in heat-treated fruit. Reduced lipase activity occurred in heat treated fruit during storage at 10 degrees C, while the fruit that was cut 24 h after treatment had a reduced peroxidase activity, unlike fruit that was processed immediately after heating. lsoelectric focussing indicated production of heat shock proteins (PI=5.1 and 6.5) as a result of heat-treatment. Textural measurements showed increased hardness, chewiness and cohesiveness, but springiness decreased in heat-treated fruit. Presence of calcium in the treatment solution did not affect respiration and textural changes caused by heat treatment. Lipase activity was, however, higher in fruit heated in calcium solutions. Results indicated the potential improvement of shelf life of cut cantaloupe melon by mild heat pre-treatment of the fruit, and that the addition of calcium to the treatment water did not further improve product quality.

The relationships between the different properties of starches were determined using Pearson's correlation analysis. Amylose content was positively correlated to hot paste viscosity (r = 0.460, P <= 0.05) and negatively correlated to transmittance measured after storage of 0, 24 and 72 h (r = -0.509, -0.480, -0.453, P <= 0.05). Hot paste viscosity showed significant positive correlation with cold paste viscosity, pasting temperature, T-p and T-c (r = 0.985, 0.607, 0.654, 0.628, P <= 0.005) and negative correlation with transmittance measured after 0, 24 and 72 h (r = -0.539, -0.570, -0.451, P <= 0.05). Breakdown viscosity showed highly negative correlation with pasting time (r = -0.766, P <= 0.005) and positive correlation with transmittance measured after 0, 24 and 72 h (r = 0.533, 0.558, 0.570, P <= 0.05). Pasting temperature showed highly positive correlation with transition temperatures T-o, T-p, T-c (r = 0.740, 0.846, 0.734, P <= 0.005) and negative correlation with transmittance measured after 0, 24 and 72 h (r = -0.418, -0.468, -0.476, P <= 0.05). T-o showed the highest positive correlation with T-p and T-c (r = 0.924, 0.755, P <= 0.005). The results revealed that temperature during tuber growth affects granule size, pasting temperature and transition temperature. Lower temperature prevailed during tubers growth resulted into starch with higher granule size and lower pasting and transition temperatures. (c) 2006 Elsevier Ltd. All rights reserved.

The good heat-stability of rice bran oil has been attributed to its high content of steryl ferulates and tocopherols. It has been suggested that these compounds have a synergistic effect as antioxidants. In this model experiment, we determined the capacity of sitostanyl ferulate and a-tocopherol (alone or as a mixture) to prevent polymerization of high oleic sunflower oil at 100 and 180 degrees C. The formation of polymers was significantly reduced at both temperatures and by both antioxidants, as well as their mixture, though no synergistic effect was seen. Further, we followed the decrease in antioxidant levels and found that sitostanyl ferulate was degraded at a lower rate than alpha-tocopherol, indicating that sitostanyl ferulate is a promising antioxidant for high temperature applications.

Linear dynamic viscoelastic properties for both gliadin and glutenin were strongly dependent on concentration. For gliadins, the storage moduli (G'), loss moduli (G"), and phase shifts dramatically changed within a narrow concentration range, indicating that gliadin suspension properties changed from viscous to viscoelastic. Glutenins exhibited viscoelastic solid behaviour at all measured concentrations. The non-linear shear viscoelastic properties of gliadin and glutenin also depended on concentration. Viscosities of gliadins displayed shear-thinning behaviour; viscosities for glutenins showed shear-thickening behaviour at low shear rates, and shear-thinning behaviour at higher shear rates. Our results indicate that gliadin's structure in suspension changes over a small concentration range, and suggest that gliadin is important in adjusting and controlling gluten's viscoelastic behaviour, and not only as a diluent of gluten's functional properties.

Six treatments and two blank incubations were conducted, testing various fresh fruits on an equal dry matter basis. Considering cholestyramine (bile acid binding, cholesterol lowering drug) as 100% bound, the relative in vitro bile acid binding percentages on dry matter (DM), total dietary fibre and total polysaccharides basis were 2-9%, 15-101% and 10-101%, respectively. Bile acid binding, on a DM basis, for bananas was significantly (P <= 0.05) higher and that for nectarines significantly lower than those for peaches, pineapple, grapes, pears and apricots. The bile acid bindings for peaches and pineapple were similar and significantly higher than those for grapes, pears and apricots. Binding values for grapes and pears were significantly higher than apricots.

Gums were evaluated for intrinsic viscosity and elastic component. Molecular conformation of the xanthan-LBG complex was assessed by the power-law and Huggins equations. Addition of any of the three salts reduced significantly the intrinsic viscosity and elastic component of the gum blends, with a pronounced effect from divalent ions, compared with monovalent ions. The 60% xanthan-40% LBG blend exhibited the strongest attraction between xanthan and LBG. For the three salts, the attraction weakened when 5-mM salt was added and vanished with the addition of 50-mM salt. The strongest attraction between xanthan and LBG molecules was also evidenced by a positive Huggins miscibility coefficient K(m), and a positive attraction-repulsion coefficient alpha. With addition of 50 mM of any of the three salts, the coefficient alpha became negative, suggesting a strong repulsion between the two gums. The power-law coefficient b increased as salt concentration and LBG fraction increased in the blends for the three salts, suggesting a more flexible xanthan-LBG complex dependent on salt concentrations and LBG.

The core issue is developing a composite measure from selected indicators of ecosystem conditions that captures the essence of the public's notions about environmental values and can be developed from existing data or by using existing data to develop proxies for key variables (indicators). This process reveals insights about the compatible nature of changes in both the composite measure and measures of socioeconomic progress. These insights suggest that there are opportunities for science to provide concise information that better informs policy or management decisions.

Herbivory on freshwater macrophytes has been assumed to be insignificant and rare. More recent evidence suggests herbivory is common and the impact of invasive invertebrate herbivores can be substantial. However, little is known about consumption of macrophytes by fish. 2. We performed a series of feeding assays, based on the consumption by common carp (Cyprinus carpio), to determine if any mechanisms of resistance, structural or chemical, were present in five species of macrophytes (Stuckenia pectinata, Typha latifolia, Scirpus validus, Chara aspera and Ceratophyllum demersum). 3. Carp consumed more fresh whole plant tissue of C. aspera than any other macrophyte, suggesting a lack of structural or chemical deterrents. Typha latifolia, S. validus and C. demersum were consumed least as whole plants, but consumption increased when they were offered in pellet form suggesting structural defence. Crude chemical extracts from S. pectinata significantly reduced consumption of pellets by carp. Thus, plant chemistry and structure both deterred feeding by carp. 4. Experiments that focus on theory are common but their application to managing landscapes is substantially lacking. Our results provide a basis for recommending plants to be used in restoring larval habitat refugia with the aim of increasing the probability for long-term recovery of an endangered species. Thus, this paper is an example of how experiments that tie theory to application are important for practical applications and for continued testing of theory. 5. We suggest that macrophyte-herbivore interactions play an integral part in aquatic food webs and may be as important in freshwater communities as in marine and terrestrial systems.

Hydrolysis of the internal beta-1,4-D-mannopyranosyl linkage in the backbone of mannans is catalyzed by endo-beta-mannanase. Plant endo-beta-mannanase has been well studied for its function in seed germination. Its involvement in other plant biological processes, however, remains poorly characterized or elusive. The completed genome sequences of Arabidopsis (Arabidopsis thaliana), rice (Oryza sativa), and poplar (Populus trichocarpa) provide an opportunity to conduct comparative genomic analysis of endo-beta-mannanase genes in these three species. In silico sequence analysis led to the identification of eight, nine and 11 endo-beta-mannanase genes in the genomes of Arabidopsis, rice, and poplar, respectively. Sequence comparisons revealed the conserved amino acids and motifs that are critical for the active site of endo-beta-mannanases. Intron/exon structure analysis in conjunction with phylogenetic analysis implied that both intron gain and intron loss has played roles in the evolution of endo-beta-mannanase genes. The phylogenetic analysis that included the endo-beta-mannanases from plants and other organisms implied that plant endo-beta-mannanases have an ancient evolutionary origin. Comprehensive expression analysis of all Arabidopsis and rice endo-beta-mannanase genes showed divergent expression patterns of individual genes, suggesting that the enzymes encoded by these genes, while carrying out the same biochemical reaction, are involved in diverse biological processes.

Although several genes related to FHB resistance have been reported, global analysis of gene expression in response to FHB infection remains to be explored. The expression patterns of transcriptomes from wheat spikes of FHB-resistant cultivar Ning 7840 and susceptible cultivar Clark were monitored during a period,of 72 h after inoculation (hai) with F graminearum. Microarray analysis, coupled with suppression subtractive hybridization technique, identified 44 significantly differentially expressed genes between cv. Ning 7840 and cv. Clark. More differentially expressed genes were identified from susceptible libraries than from resistance libraries. The up-regulation of defense-related genes in Ning 7840 relative to cultivar Clark occurred during early fungal stress (3-12 hai). Three genes, with unknown function that were up-regulated in cv. Ning 7840 at most time points investigated, might play an important role in enhancing FHB resistance. C1 Kansas State Univ, USDA ARS, Plant Soil & Entomol Res Unit, Manhattan, KS 66506 USA.

L.]. The experimental system minimised environmental effects and was conducted in reference design, where samples from untreated controls acted as references against post-treatment samples. Microarray observations were also validated by quantitative reverse transcription-polymerase chain reaction. The time-course expression patterns of 715 experimental microarray features resulted in differential expression of 425 transcripts. The A. rabiei resistant chickpea genotypes showed a more substantial range of defence-related gene induction by all treatments, indicating that they may possess stronger abilities to resist pathogens. Further, the involvement of SA, MeJA and ACC signalling was identified for the regulation of some important A. rabiei responsive transcripts, as well as cross-talk between these pathways. In the current study we also found evidence to suggest the involvement of A. rabiei-specific signalling mechanisms for the induction of several transcripts that were previously implicated in A. rabiei resistance. This study characterised the regulatory mechanisms of many chickpea transcripts that may be important in defence against various pathogens, as well as other cellular functions. These results provide novel insights to the molecular control of chickpea cellular processes, which may assist the understanding of chickpea defence mechanisms and allow enhanced development of disease resistant cultivars.

TI Genetic evidence for differences in the pathways of druse and prismatic calcium oxalate crystal formation in Medicago truncatula SO FUNCTIONAL PLANT BIOLOGY LA English DT Article ID L-ASCORBIC-ACID; OXALIC-ACID; ACCUMULATING PLANTS; PISTIA-STRATIOTES; GLYCOLATE-OXIDASE; YUCCA-TORREYI; BIOSYNTHESIS; IDIOBLASTS; LEAVES; CONVERSION AB Current evidence supports a single pathway of oxalate biosynthesis utilising ascorbic acid as the precursor. In this study, we begin to address the possibility that more than one pathway of oxalate biosynthesis and calcium oxalate formation occurs in Medicago truncatula Gaertn. (cv. Jemalong genotype A17). Like the wild type, developing leaves of the calcium oxalate defective (cod) 4 mutant contain prismatic crystals along the vascular strand, but this mutant also hyper-accumulates druse crystals within the mesophyll cells. A second mutant, cod5, fails to accumulate prismatic crystals along the vascular strand, but is capable of wild type druse crystal accumulation in maturing leaves. To assess whether a single pathway of oxalate biosynthesis and calcium oxalate formation occurs in M. truncatula, we generated and characterised the cod4/cod5 double mutant. Microscopic examination of the cod4/cod5 revealed that the double mutant exhibits both cod4 and cod5 mutant crystal phenotypes simultaneously, suggesting there are differences in the pathways leading to the two crystal types. Measured ascorbic acid levels and ascorbate induction studies were consistent with the acid as precursor to oxalate in druse crystal formation but not necessarily prismatic crystal formation. On the basis of these findings, we propose a working model depicting possible pathways of oxalate biosynthesis and calcium oxalate formation.

Cuphea wrightii A. Gray, C. laminuligera Koehne, C. carthagenensis (Jacq.) J.F. Macbr. and C. aequipetala Cav are considered sensitive to low temperature storage. The seeds of these species have triacylglycerols (TAG) that are crystalline at -18 degrees C and melt when the seeds are warmed to > 35 degrees C. In contrast, seeds of tolerant species, C. lanceolata W.T. Aiton and C. hookeriana Walp., have TAG that crystallise at temperatures below -18 degrees C and are fluid at 22 degrees C. Cuphea seeds imbided while TAG are crystalline fail to germinate and exhibit visual damage. However, germination proceeded normally when dry seeds were warmed adequately to melt any crystalline TAG before imbibition. Reduced germination and cellular disruption including loss of lipid body compartmentation and fragmented protein bodies develop in seeds with crystalline TAG equilibrated to > 0.1 g H2O g(-1) DW. This damage cannot be reversed, even when seeds are dried before the damage can be visually detected. Results from this work reveal that the seeds of some species with intermediate type physiologies can be successfully placed into conventional -18 and -80 degrees C storage facilities.

To accelerate molecular breeding efforts for the discovery and introgression of stress tolerance genes into cultivated chickpea, functional genomics approaches are rapidly growing. Recently a series of genetic tools for chickpea have become available that have allowed high-powered functional genomics studies to proceed, including a dense genetic map, large insert genome libraries, expressed sequence tag libraries, microarrays, serial analysis of gene expression, transgenics and reverse genetics. This review summarises the development of these genomic tools and the achievements made in initial and emerging functional genomics studies. Much of the initial research focused on Ascochyta blight resistance, and a resistance model has been synthesised based on the results of various studies. Use of the rich comparative genomics resources from the model legumes Medicago truncatula and Lotus japonicus is also discussed. Finally, perspectives on the future directions for chickpea functional genomics, with the goal of developing elite chickpea cultivars, are discussed.

We quantified the influence of leaf litter inputs on aquatic invertebrates in two seasonal woodland ponds using an interception experiment. Ponds were hydrologically split using a sandbag-plastic barrier, and a mesh canopy was suspended over one-half of each pond to intercept autumn leaf fall for four years. Subsequently the mesh canopies were removed so recovery could be assessed. In one wetland pond, overall invertebrate biomass and the biomass of certain functional groups declined in the interception half-pond and then rapidly recovered after litter inputs were restored. In this pond, leaf litter was a crucial resource to invertebrates, which is consistent with findings in other detritus-dominated ecosystems. However, in the second wetland pond the relationship between litter and invertebrates was very different, and interception appeared to benefit rather than harm invertebrates. Invertebrates were sensitive to changes in leaf litter input in both ponds, but interactions were not consistent. Highly variable wetland conditions in ponds (seasonal drying, stagnant water) may complicate litter-invertebrate interaction in these habitats. C1 Univ Georgia, Dept Entomol, Athens, GA 30602 USA.

Like many fungi, U. maydis undergoes remarkable morphological transitions throughout its life cycle. Fusion of compatible, budding, haploid cells leads to the production of a filamentous dikaryon that penetrates and colonizes the plant, culminating in the production of diploid teliospores within fungal-induced plant galls or tumors. These dramatic morphological transitions are controlled by components of various signaling pathways, including the pheromone-responsive MAP kinase and cAMP/PKA (cyclic AMP/protein kinase A) pathways, which coregulate the dimorphic switch and sexual development of U. maydis. These signaling pathways must somehow cooperate with the regulation of the cytoskeletal and cell cycle machinery. In this chapter, we provide an overview of these processes from pheromone perception and mating to gall production and sporulation in planta. Emphasis is placed on the genetic determinants of morphogenesis and pathogenic development of U. maydis and on the fungus-host interaction. Additionally, we review advances in the development of tools to study U. maydis, including the recently available genome sequence. We conclude with a brief assessment of current challenges and future directions for the genetic study of U. maydis. (C) 2007, Elsevier Inc.

Sex influences the risk of nearly all common diseases that affect both men and women, including atherosclerosis and diabetes and their preceding risk factors (eg, hyperlipidemia, insulin resistance, and obesity). Objective: The goal of this article was to examine the interplay between genes, gender, and disease susceptibility, and assess it in the context of the added complexity of environmental factors (ie, dietary habits, smoking, alcohol consumption) in the modulation of the balance between health and disease. Methods: Original and review articles published by the author were reexamined for evidence of gene-gender interactions. Results: Evidence from some key factors in lipid metabolism (apolipoprotein E [APOE]) and obesity (perilipin [PLIN]) indicates that the interplay between genes, gender, and environmental factors modulates disease susceptibility. In the Framingham Heart Study, complex interactions have been shown between a promoter polymorphism at the apolipoprotein A1 gene, gender, and dietary polyunsaturated fatty acid intake that modulate plasma concentrations of high-density lipoprotein cholesterol. Likewise, highly and clinically relevant interactions have been observed between the APOE gene common alleles APOE2, APOE3, and APOE4, gender, and smoking that determine cardiovascular disease risk. Most interesting is the gender-dependent association between common polymorphisms at the PLIN locus and obesity risk that has been replicated in several populations around the world. Conclusions: These data support the idea that gender-specific differences in morbidity and mortality may be mediated in part by genetic factors and by their differential response to the environment. The new knowledge generated by a more careful and complete elucidation of the complex interactions predisposing to common diseases will result in an increased ability to provide successful personalized behavioral recommendations to prevent chronic disorders.

Wood property traits SO GENETICS LA English DT Article ID CONTROLLING ADAPTIVE TRAITS; COASTAL DOUGLAS-FIR; CINNAMYL ALCOHOL-DEHYDROGENASE; LOBLOLLY-PINE; LINKAGE DISEQUILIBRIUM; FLOWERING TIME; CANDIDATE GENES; NUCLEOTIDE DIVERSITY; POPULATION-STRUCTURE; COLD-HARDINESS AB Genetic association is a powerful method for dissecting complex adaptive traits due to (i) fine-scale mapping resulting from historical recombination, (ii) wide coverage of phenotypic and genotypic variation within a single experiment, and (iii) the simultaneous discovery of loci and alleles. In this article, genetic association among single nucleotide polymorphisrns (58 SNPs) from 20 wood- and drought-related candidate genes and an array of wood property traits with evolutionary and commercial importance, namely, earlywood and latewood specific gravity, percentage of latewood, earlywood microfibril angle, and wood chemistry (lignin and cellulose content), was tested using mixed linear models (MLMs) that account for relatedness among individuals by using a pairwise kinship matrix. Population structure, a common systematic bias in association studies, was assessed using 22 nuclear microsatellites. Different phenotype: genotype associations were found, some of them confirming previous evidence from collocation of QTL and genes in linkage maps (for example, 4cl and percentage of latewood) and two that involve nonsynonymous polymorphisms (cad SNP M28 with earlywood specific gravity and 4cl SNP M7 with percentage of latewood). The strongest genetic association found in this study was between allelic variation in alpha-tubulin, a gene involved in the formation of cortical microtubules, and earlywood microfibril angle. Intragenic LD decays rapidly in conifers; thus SNPs showing genetic association are likely to be located in close proximity to the causative polymorphisms. This first multigene association genetic study in forest trees has shown the feasibility of candidate gene strategies for dissecting complex adaptive traits, provided that genes belonging to key pathways and appropriate statistical tools are used. This approach is of particular utility in species such as conifers, where genomewide strategies are limited by their large genomes. C1 Univ Calif Davis, Dept Plant Sci, Davis, CA 95616 USA.

We analyzed the birth weight and weight at 60 days QTL segregating on bovine chromosome BTA14 in a F2 resource population using genotypes produced from seven microsatellite markers. Phenotypes were derived from 346 F2 progeny produced from crossing Bos indicus Gyr x Holstein Bos taurus F1 parents. Interval analysis to detect QTL for birth weight revealed the presence of a QTL (p < 0.05) at 1 centimorgan (cM) from the centromere with an additive effect of 1.210 +/- 0.438 kg. Interval analysis for weight at 60 days revealed the presence of a QTL (p < 0.05) at 0 cM from the centromere with an additive effect of 2.122 +/- 0.735 kg. The region to which the QTL were assigned is described in the literature as responsible for some growth traits, milk yield, milk composition, fat deposition and has also been related to reproductive traits such as daughter pregnancy rate and ovulation rate. The effects of the QTL described on other traits were not investigated. C1 EMBRAPA, BR-13560970 Sao Carlos, SP, Brazil.

Correlations among yield traits and somatic cell score were estimated with three different models: 1) bovine somatotropin (bST) administration ignored, 2) bST administration as a fixed effect and 3) administration of bST as part of the contemporary group (herd-year-month-bST). Heritability estimates ranged from 0.13 to 0.17 for milk, 0.12 to 0.20 for fat, 0.14 to 0.16 for protein yields, and 0.08 to 0.09 for somatic cell score. Estimates were less for later than first lactations. Estimates of genetic correlations among yields ranged from 0.35 to 0.85 with no important differences between estimates with the 3 models. Estimates for lactation 2 agreed with estimates for lactation 1. Estimates of genetic correlations for later lactations were generally greater than for lactations 1 and 2 except between milk and protein yields. Estimates of genetic correlations between yields and somatic cell score were mostly negative or small (- 0.45 to 0.11). Estimates of environmental correlations among yield traits were similar with all models (0.77 to 0.97). Estimates of environmental correlations between yields and somatic cell score were negative (- 0.22 to - 0.14). Estimates of phenotypic correlations among yield traits ranged from 0.70 to 0.95. Estimates of phenotypic correlations between yields and somatic cell score were small and negative. For all three data sets and all traits, no important differences in estimates of genetic parameters were found for the two models that adjusted for bST and the model that did not.

Data set 1 included 65,720 first-lactation records. Set 2 included 50,644 second-lactation records. Set 3 included 45,505 records for lactations three, four and five. Estimated breeding values (EBV) of sires were with three different animal models. With Model 1, bST administration was ignored. With Model 2, bST administration was used as a fixed effect. With Model 3, administration of bST was used to define the contemporary group (herd-year-month of calving-bST). Correlations for EBV of 1,366 sires with treated daughters between pairs of the three models were calculated for milk, fat and protein yields and somatic cell score for the three data sets. Correlations for EBV of sires between pairs of models for all traits ranged from 0.971 to 0.999. Fractions of sires with bST- treated progeny selected in common (top 10 to 15%) were 0.94 and usually greater for all pairs of models for all traits and parities. For this study, the method of statistical adjustment for bST treatment resulted in a negligible effect on genetic evaluations of sires when some daughters were treated with bST and suggests that selection of sires to produce the next generation of sires and cows might not be significantly affected by how the effect of bST is modeled for prediction of breeding values for milk, fat and protein yields and somatic cell score.

The largest class of identifiable ESTs (15.2%) was from genes involved in cellular metabolic functions, including physiological processes. Twenty- seven ESTs (9.8%) were from genes associated with transcription and translation, including ribosomal genes. One hundred and forty-two of the 276 unique ESTs were from genes not previously identified from any organism. Twelve sequences appear to be associated with feeding and digestion and may be targets for pest control studies. C1 [Allen, M. L.] USDA, ARS, Biol Control Pests Res Unit, Stoneville, MS 38776 USA.

TI Estimates of genetic parameters for Holstein cows for test-day yield traits with a random regression cubic spline model SO GENETICS AND MOLECULAR RESEARCH LA English DT Article DE random regression; genetic parameters; cubic spline ID DAIRY-CATTLE; LACTATION; COVARIANCE; GROWTH AB Genetic parameters were estimated with restricted maximum likelihood for individual test-day milk, fat, and protein yields and somatic cell scores with a random regression cubic spline model. Test-day records of Holstein cows that calved from 1994 through early 1999 were obtained from Dairy Records Management Systems in Raleigh, North Carolina, for the analysis. Estimates of heritability for individual test-days and estimates of genetic and phenotypic correlations between test-days were obtained from estimates of variances and covariances from the cubic spline analysis. Estimates were calculated of genetic parameters for the averages of the test days within each of the ten 30-day test intervals. The model included herd test-day, age at first calving, and bovine somatropin treatment as fixed factors. Cubic splines were fitted for the overall lactation curve and for random additive genetic and permanent environmental effects, with five predetermined knots or four intervals between days 0, 50, 135, 220, and 305. Estimates of heritability for lactation one ranged from 0.10 to 0.15, 0.06 to 0.10, 0.09 to 0.15, and 0.02 to 0.06 for test-day one to test-day 10 for milk, fat, and protein yields and somatic cell scores, respectively. Estimates of heritability were greater in lactations two and three. Estimates of heritability increased over the course of the lactation. Estimates of genetic and phenotypic correlations were smaller for test-days further apart. C1 [DeGroot, B. J.; Keown, J. F.; Kachman, S. D.] Univ Nebraska, Dept Anim Sci, Lincoln, NE 68583 USA.

TI Computing numerator relationships between any pair of animals SO GENETICS AND MOLECULAR RESEARCH LA English DT Article DE inbreeding coefficient; pairs of animals; numerator relationships ID RELATIONSHIP MATRIX; INVERSE; COEFFICIENTS AB We describe a simple method to compute the numerator relationship between any or all pairs of animals in the numerator relationship matrix. The method depends on output of the MTDFNRM program from the MTDFREML set of programs. An option of the MTDFNRM program creates a file that includes the inbreeding coefficient for each animal. The method also makes use of how the inbreeding coefficient is traditionally calculated: one-half of the relationship between the animal's parents. To obtain the numerator relationship between any pair of animals, the original pedigree file is augmented with a dummy animal with an identification number (ID) greater than for any animal in the original pedigree file. The ID of the pair of animals for which the relationship is wanted is included as parents. MTDFNRM is then run with the option to create a file of ordered and original IDs for animals and their parents along with the inbreeding coefficients. We then multiply the inbreeding coefficient for a dummy animal by two to obtain the numerator relationship between the two animals designated as parents.

Moench is an important grain and forage crop grown worldwide. We developed a simple sequence repeat (SSR) linkage map for sorghum using 352 publicly available SSR primer pairs and a population of 277 F-2 individuals derived from a cross between the Westland A line and PI 550610. A total of 132 SSR loci appeared polymorphic in the mapping population, and 118 SSRs were mapped to 16 linkage groups. These mapped SSR loci were distributed throughout 10 chromosomes of sorghum, and spanned a distance of 997.5 cM. More important, 38 new SSR loci were added to the sorghum genetic map in this study. The mapping result also showed that chromosomes SBI-01, SBI-02, SBI-05, and SBI-06 each had 1 linkage group; the other 6 chromosomes were composed of 2 linkage groups each. Except for 5 closely linked marker flips and 1 locus (Sb6_34), the marker order of this map was collinear to a published sorghum map, and the genetic distances of common marker intervals were similar, with a difference ratio <= 0.05 between the 2 maps. The difference ratio is a new index developed in this study that can be used to compare the genetic distances of DNA markers between 2 maps. This SSR map carrying additional SSR markers will facilitate mapping quantitative trait loci to the sorghum genome and map-based gene cloning. Furthermore, the novel method for calculating distance between DNA markers will be a useful tool for the comparative analysis of genetic markers between linkage maps with different genetic backgrounds and the alignment of different sorghum genetic maps.

CA Int Sheep Genomics Consortium TI Using comparative genomics to reorder the human genome sequence into a virtual sheep genome SO GENOME BIOLOGY LA English DT Article ID MAMMALIAN CHROMOSOME EVOLUTION; LINKAGE MAP; PHYSICAL MAP; MOUSE; CONSTRUCTION; REARRANGEMENT; STABILITY; DATABASE; BROWSER; UPDATE AB Background: Is it possible to construct an accurate and detailed subgene-level map of a genome using bacterial artificial chromosome (BAC) end sequences, a sparse marker map, and the sequences of other genomes? Results: A sheep BAC library, CHORI-243, was constructed and the BAC end sequences were determined and mapped with high sensitivity and low specificity onto the frameworks of the human, dog, and cow genomes. To maximize genome coverage, the coordinates of all BAC end sequence hits to the cow and dog genomes were also converted to the equivalent human genome coordinates. The 84,624 sheep BACs ( about 5.4-fold genome coverage) with paired ends in the correct orientation ( tail-to-tail) and spacing, combined with information from sheep BAC comparative genome contigs ( CGCs) built separately on the dog and cow genomes, were used to construct 1,172 sheep BAC-CGCs, covering 91.2% of the human genome. Clustered non-tail-to-tail and outsize BACs located close to the ends of many BAC-CGCs linked BAC-CGCs covering about 70% of the genome to at least one other BAC-CGC on the same chromosome. Using the BAC-CGCs, the intrachromosomal and interchromosomal BAC-CGC linkage information, human/cow and vertebrate synteny, and the sheep marker map, a virtual sheep genome was constructed. To identify BACs potentially located in gaps between BAC-CGCs, an additional set of 55,668 sheep BACs were positioned on the sheep genome with lower confidence. A coordinate conversion process allowed us to transfer human genes and other genome features to the virtual sheep genome to display on a sheep genome browser. Conclusion: We demonstrate that limited sequencing of BACs combined with positioning on a well assembled genome and integrating locations from other less well assembled genomes can yield extensive, detailed subgene- level maps of mammalian genomes, for which genomic resources are currently limited.

It also has substantial economic importance for meat-based protein production. Physical clone maps have underpinned large-scale genomic sequencing and enabled focused cloning efforts for many genomes. Comparative genetic maps indicate that there is more structural similarity between pig and human than, for example, mouse and human, and we have used this close relationship between human and pig as a way of facilitating map construction. Results: Here we report the construction of the most highly continuous bacterial artificial chromosome ( BAC) map of any mammalian genome, for the pig ( Sus scrofa domestica) genome. The map provides a template for the generation and assembly of high-quality anchored sequence across the genome. The physical map integrates previous landmark maps with restriction fingerprints and BAC end sequences from over 260,000 BACs derived from 4 BAC libraries and takes advantage of alignments to the human genome to improve the continuity and local ordering of the clone contigs. We estimate that over 98% of the euchromatin of the 18 pig autosomes and the X chromosome along with localized coverage on Y is represented in 172 contigs, with chromosome 13 ( 218 Mb) represented by a single contig. The map is accessible through pre-Ensembl, where links to marker and sequence data can be found. Conclusion: The map will enable immediate electronic positional cloning of genes, benefiting the pig research community and further facilitating use of the pig as an alternative animal model for human disease. The clone map and BAC end sequence data can also help to support the assembly of maps and genome sequences of other artiodactyls. C1 Wellcome Trust Sanger Inst, Cambridge CB10 1SA, England.

Previously described genetic and radiation hybrid (RH) maps of the bovine genome have been used to identify genomic regions and genes affecting specific traits. Application of these maps to identify influential genetic polymorphisms will be enhanced by integration with each other and with bacterial artificial chromosome (BAC) libraries. The BAC libraries and clone maps are essential for the hybrid clone-byclone/whole-genome shotgun sequencing approach taken by the bovine genome sequencing project. Results: A bovine BAC map was constructed with HindIII restriction digest fragments of 290,797 BAC clones from animals of three different breeds. Comparative mapping of 422,522 BAC end sequences assisted with BAC map ordering and assembly. Genotypes and pedigree from two genetic maps and marker scores from three whole-genome RH panels were consolidated on a 17,254-marker composite map. Sequence similarity allowed integrating the BAC and composite maps with the bovine draft assembly (Btau3.1), establishing a comprehensive resource describing the bovine genome. Agreement between the marker and BAC maps and the draft assembly is high, although discrepancies exist. The composite and BAC maps are more similar than either is to the draft assembly. Conclusion: Further refinement of the maps and greater integration into the genome assembly process may contribute to a high quality assembly. The maps provide resources to associate phenotypic variation with underlying genomic variation, and are crucial resources for understanding the biology underpinning this important ruminant species so closely associated with humans.

TI Computational and transcriptional evidence for microRNAs in the honey bee genome SO GENOME BIOLOGY LA English DT Article ID CAENORHABDITIS-ELEGANS/; GENE-EXPRESSION; TARGET; DROSOPHILA; RNAS; IDENTIFICATION; SEQUENCES; EVOLUTION; INSECTS AB Background: Non-coding microRNAs (miRNAs) are key regulators of gene expression in eukaryotes. Insect miRNAs help regulate the levels of proteins involved with development, metabolism, and other life history traits. The recently sequenced honey bee genome provides an opportunity to detect novel miRNAs in both this species and others, and to begin to infer the roles of miRNAs in honey bee development. Results: Three independent computational surveys of the assembled honey bee genome identified a total of 65 non-redundant candidate miRNAs, several of which appear to have previously unrecognized orthologs in the Drosophila genome. A subset of these candidate miRNAs were screened for expression by quantitative RT-PCR and/or genome tiling arrays and most predicted miRNAs were confirmed as being expressed in at least one honey bee tissue. Interestingly, the transcript abundance for several known and novel miRNAs displayed caste or age-related differences in honey bees. Genes in proximity to miRNAs in the bee genome are disproportionately associated with the Gene Ontology terms 'physiological process', 'nucleus' and 'response to stress'. Conclusion: Computational approaches successfully identified miRNAs in the honey bee and indicated previously unrecognized miRNAs in the well-studied Drosophila melanogaster genome despite the 280 million year distance between these insects. Differentially transcribed miRNAs are likely to be involved in regulating honey bee development, and arguably in the extreme developmental switch between sterile worker bees and highly fertile queens.

Components of the innate immune system are hardly known in this insect, which is in a key phylogenetic position to inform us about genetic innovations accompanying the evolution of holometabolous insects. We have annotated immunity-related genes and compared them with homologous molecules from other species. Results: Around 300 candidate defense proteins are identified based on sequence similarity to homologs known to participate in immune responses. In most cases, paralog counts are lower than those of Drosophila melanogaster or Anopheles gambiae but are substantially higher than those of Apis mellifera. The genome contains probable orthologs for nearly all members of the Toll, IMD, and JAK/STAT pathways. While total numbers of the clip-domain serine proteinases are approximately equal in the fly (29), mosquito (32) and beetle (30), lineage-specific expansion of the family is discovered in all three species. Sixteen of the thirty-one serpin genes form a large cluster in a 50 kb region that resulted from extensive gene duplications. Among the nine Toll-like proteins, four are orthologous to Drosophila Toll. The presence of scavenger receptors and other related proteins indicates a role of cellular responses in the entire system. The structures of some antimicrobial peptides drastically differ from those in other orders of insects. Conclusion: A framework of information on Tribolium immunity is established, which may serve as a stepping stone for future genetic analyses of defense responses in a nondrosophiline genetic model insect.

To determine ragweed longevity, we exposed disturbed soil with a common seed bank population to an in situ temperature and [CO2] gradient along an urban-rural transect beginning in early 2002. No other consistent differences in meteorological variables (e.g. wind speed, humidity, PAR, tropospheric ozone) as a function of urbanization were documented over the course of the study (2002-2005). Above-ground measurements of biomass over this period demonstrated that ragweed along the transect responded to urban induced increases in [CO2]/temperature with peak biomass being observed at this location by the end of 2003. However, by the Fall of 2004, and continuing through 2005, urban ragweed populations had dwindled to a few plants. The temporal decline in ragweed populations was not associated with increased disease, herbivory or auto-allelopathy, but was part of a demographic reduction in the total number of annual plant species observed for the urban location. In a separate experiment, we showed that such a demographic shift is consistent with CO2/temperature induced increases in biomass and litter accumulation, with a subsequent reduction in germination/survival of annual plant species. Overall, these data indicate that [CO2]/temperature differences associated with urbanization may increase initial ragweed productivity and pollen production, but suggest that long-term, multi-year persistence of ragweed in the urban macro-environment may be dependent on other factors.

These objectives hinge on landscape pattern, so we refer to these methods as "spatial optimization." It is currently possible to directly capture deterministic characterizations of the most basic spatial relationships: proximity relationships (including those that lead to edge effects), habitat connectivity/fragmentation relationships, population growth and dispersal, and patch size/habitat amount thresholds. More complex spatial relationships and stochastic relationships are currently best captured through heuristic manipulation of simulation models. General treatment of stochastic variables in spatial optimization is in its infancy. C1 [Hof, John] US Forest Serv, Rocky Mt Res Stn, USDA, Ft Collins, CO USA.

A large literature includes both quantitative (caloric restriction [CRI]) and qualitative (micronutrients, antioxidants, etc.) alterations of nutrient and caloric intake and the resulting positive outcomes for age-related disease protection, maintenance of vitality, and quantitative and qualitative life-span extension. In recognition of the importance of this research area, two sessions concerning nutritional interventions in aging and age-associated diseases were organized for this symposium, one dealing with diet and the other with dietary supplements. This brief report covers both, providing selected examples of the most recent research into both these types of interventions and their mechanisms of action.

TI Violet light causes photodegradation of wood beyond the zone affected by ultraviolet radiation SO HOLZFORSCHUNG LA English DT Article DE depth profile; FT-IR; photodegradation; sugi wood; ultraviolet radiation; violet light; visible light; wavelength ID CRYPTOMERIA-JAPONICA; DEPTH PROFILE; DEGRADATION; IRRADIATION; PENETRATION; SURFACES; COLOR AB The limited penetration of wood by light explains why the weathering of wood exposed outdoors is a surface phenomenon. Wood is rapidly degraded by short-wavelength UV radiation, but the penetration of light into wood is positively correlated with its wavelength. Hence, subsurface degradation is likely to be caused by longer-wavelength light that still has sufficient energy to degrade wood. In this paper we test this hypothesis and determine the wavelengths of visible light that extend photo-degradation into wood beyond the zone affected by UV radiation. Sugi (Cryptomeria japonica) earlywood was exposed to UV and visible light with narrow band gaps (20 nm) and the penetration of light into the wood was measured using a photodetector. Photodegradation was depth-profiled using FT-IR microscopy. There was a positive correlation between the penetration of light into sugi earlywood and the wavelength of the incident radiation within the range 246-496 nm. The depth of photodegradation also increased with wavelength up to and including the violet region (403 nm) of the visible spectrum. Blue light (434-496 nm) penetrated wood to a greater extent than violet light and was capable of bleaching the wood, but it did not significantly modify lignin, and hence it was not responsible for sub-surface photodegradation of wood. We conclude that violet light is the component of the visible spectrum that extends photodegradation into wood beyond the zone affected by UV radiation. Accordingly, surface treatments designed to protect wood used outdoors should shield wood from the effects of violet light.

Atomic force microscopy examination of untreated samples of these laid paper sheets revealed notable surface inhomogeneity. Diffuse brightness values show that irradiation resulted in an initial decrease followed by a rapid increase in brightness with increasing irradiation time from 0.5 to 28 h. The bleaching effect then slowed, following a logarithmic path that did not plateau within 197 h of irradiation time. Irradiated sheets stored for 3 months exhibited brightness reversion of 7%. Fluorescence also decreased with irradiation time if excitation wavelengths of 320, 350, and 400 nm were applied for samples exposed to narrow-band irradiation at 350 nm. The fold endurance decreased by 34-72% after 197 h of irradiation. Changes in tear and tensile values were less dramatic. The Z-direction ultrasonic velocity decreased after 197 h of irradiation; however, the ultrasonic conductivity partially recovered during 9 months of storage.

When mechanical pulps were produced from these pretreated chips, savings in electrical refiner energy could be achieved. For southern yellow pine (Pinus taeda), the electrical refiner energy required to produce pulps with Canadian standard freeness (CSF) of 100 ml was 3855% less than for an untreated control. Energy savings were also observed for aspen (Populus spp.) and spruce (Picea spp.). DEO-treated pine handsheets showed a 26% improvement in tear index compared with a control at 100 ml CSF. Under the pretreatment conditions described, DEO rapidly vaporizes, reacts with water already present in the chip, and forms an oxalic acid (OA) solution. Reported handsheet properties and energy savings for pine chips treated with a solution of OA are similar to DEO-treated handsheets. It can be concluded that the effect of DEO treatment is due to reactions catalyzed by OA. C1 USDA ARS, Forest Prod Lab, Madison, WI 53726 USA. Biopulping Int Inc, Madison, WI USA.

Under these conditions, DEO hydrolyzes to ethanol and oxalic acid (OA). The amount and identity of carbohydrates released from the chips were species-dependent. For all wood species, increasing the amount of chemical, time, or temperature resulted in an increment in carbohydrates released. Approximately 50% (by wt) of extracted carbohydrates were monosaccharides. In addition, acetic acid was detected in the water extracts. When extracts were subsequently alkali ne-treated, more acetate was released, indicating the presence of acetyl esters. The composition of water extracts and of wood chips after treatment indicates that these treatments primarily affect hemicelluloses. In summary, treatment of wood chips with DEO or OA releases carbohydrates suitable for fermentation, with no evidence of cellulose degradation. C1 USDA ARS, Forest Prod Lab, Madison, WI 53726 USA.

The results indicate that fiber charge increased with an increase in peroxide charge: a maximum fiber charge increment of 16.6% was obtained with 8.0% more peroxide charge on oven-dried (o.d.) pulp at 60.0 degrees C. Two primary bleaching temperatures of 60.0 degrees C and 90.0 degrees C were investigated during peroxide treatment. Copper number decreased for peroxide charges of 0.5% and 1.0% at 60.0 degrees C and 90.0 degrees C, respectively, then increased with increasing peroxide charge. Both fiber charge and copper number approached constant values when 4.0% or higher peroxide charge was applied. Peroxide treatment on a bleached kraft pulp at 90.0 degrees C resulted in lower fiber charge and lower intrinsic viscosity compared to treatment at 60.0 degrees C. Sodium borohydride (NaBH4) pretreatment was able to protect the fibers from being degraded during peroxide bleaching. Fiber charge and copper number were compared after peroxide treatment of ECF bleached kraft pulp to NaBH4-reduced ECF bleached kraft pulp. The results indicate that the carbonyl group content of fibers is favorable for improving fiber charge after peroxide treatment. C1 Georgia Inst Technol, Sch Chem & Biochem, Atlanta, GA 30332 USA.

Two pulps were investigated: (1) a softwood (SW) kraft pulp (KP) which was bleached elementally chlorine-free (ECF) and served as control; and (2) a control pulp treated with alkaline peroxide, which had a higher fiber charge. It was shown that increased fiber charge can improve the efficiency of the refining treatment, as indicated by differences in tensile index refined from 0 to 1000 revolutions. When the control pulp was refined from 4000 to 8000 revolutions, the tensile index decreased. In contrast, the tensile index of the higher fiber charge pulp (HCP) was higher under the same refining conditions. Upon addition of 2% cationic starch to both pulps, the tensile index of the control pulp increased by 13.7% and that of HOP by 23.7%. Atomic force microscopy did not reveal differences in the surface morphology of the two pulps with and without cationic starch adsorption. Peroxide treatment enhanced the fiber charge of the never-dried pulp. This was beneficial in reducing hornification when pulp was dried at 105 degrees C. However, if the once dried pulp at 105 degrees C was treated with peroxide, this resulted in a drastic decrease in intrinsic viscosity of the pulp and lower tensile and burst indices of the test sheets.

TI Field assessment of wood stake decomposition in forest soil SO HOLZFORSCHUNG LA English DT Article DE acoustic wave; biodegradation; decomposition; modulus of elasticity; pulse echo; residual compressive strength; weight loss; wood stake AB A pulse-echo acoustic method was investigated for evaluating wood stake decomposition in the field. A total of 58 wood stakes (29 loblolly pine, Pinus taeda, and 29 aspen, Populus tremuloides) that were vertically installed (full length) in forest soils were non-destructively tested by means of a laboratory-type acoustic measurement system. The same acoustic measurements were also conducted on the wood stakes after they were removed from the soil. Compression (parallel to grain) tests were then performed on the stakes in the laboratory to obtain residual elastic and strength properties. The results indicate that the pulse-echo acoustic method is a good approach to characterize wood stakes that are fully inserted into mineral soils. Statistical analysis showed good relationships between acoustic parameters (number of pulse echoes and in-ground acoustic velocity) and percentage weight loss, modulus of elasticity in compression, and residual compressive strength. The pulse-echo acoustic method could be used as a monitoring tool to assess progressive levels of wood stake decomposition in forest soil. C1 USDA, Forest Prod Lab, Madison, WI 53726 USA.

TI Contemplating risk assessment: A critique of NRC (1983,1996) SO HUMAN AND ECOLOGICAL RISK ASSESSMENT LA English DT Article; Proceedings Paper CT BOSC Workshop on USEPA Risk Assessment Principles and Practices CY FEB 02-03, 2005 CL Washington, DC SP BOSC DE risk characterization; falsification; weight of evidence; stakeholders AB Assessing risks involves developing predictive mathematical models, using interpretations of data that are based on scientific assumptions or theories and knowledge of how the data were created. The predictions are used for developing strategies that affect many people in society. Often, it is sufficient that the models that are used are justifiable by a well-accepted set of assumptions or theories, reflecting the state-of-the art science at the time. However, this does not ensure that the "best" decision would be made, nor does it ensure that the decision processes would be fair by ensuring that concerned and affected individuals would be able to participate, effectively presenting arguments on their own behalf Because of these concerns, procedures of risk analysis, including the management of the process, have been written about, for example, in a National Research Council (NRC 1996) publication, with the intention of getting stakeholders (interested participants) more involved in the risk analysis process. This publication suggests that Risk Characterization be expanded to include an active participation of stakeholders. Such an expansion would affect the risk assessor's approach toward science compared to the present approach, as implied in the seminal NRC (1983) publication. Both of these NRC publications have had great influence on the development of risk analysis management and policy in the United States and elsewhere. Subsequent risk assessment guidance documents have generally relied heavily on these publications, but have focused mainly on managerial attitudes (or policy) toward the uncertainty that is inherent in risk assessment and in communicating to the public the risk assessment conclusions and decisions made from them. Subsequent documents have not, unlike NRC (1996), focused on the risk assessors' attitude toward science inference that would better help ensure that risk assessments contain the type of information that could be used to empower stakeholders. Thus, in this Perspective article I focus on the two NRC "foundation documents," identifying and contrasting two types of approaches toward science, one narrow and the other expansive. The latter approach is designed to increase stakeholders' involvement more than the former. The features of the expansive approach include a contemplative method toward science, where the risk assessor does not express opinions or take a stand regarding the scientific material, but rather considers many possibilities, presents discussions that include direct challenges to assumptions, and uses falsification principles for excluding theories.

To evaluate the effects of travertine deposition on the aquatic food base we used leaf litterbags to compare decomposition rates and nutrient diffusing artificial substrates to compare algal accrual rates and nutrient limitation between two distinct reaches in Fossil creek: a travertine dam forming reach and a reach without travertine dam formation (riffle-pool reach). Decomposition was significantly faster in the travertine dam forming reach than in the riffle-pool reach. Macroinvertebrates in the leaf packs were more diverse in the travertine reach but more abundant in the riffle-pool reach. Algae accrued more quickly in the travertine reach than in the riffle-pool reach and only responded to nutrient enrichment in the travertine reach. This study was conducted prior to a hydroelectric dam decommissioning project in Fossil Creek where full flows were reintroduced back into the stream after a century of diversion. Our results suggest concurrent increases in algal productivity, decomposition, and macroinvertebrate diversity in the next decade as travertine dams rebuild, providing a richer food base for fish and other aquatic organisms.

We hypothesized that litter exclusion would lead to a reduction in all chironomids at both the subfamily and generic levels because organic matter serves as both food and habitat in these headwater streams. Tanytarsini total abundance and biomass significantly declined after litter exclusion. Before litter exclusion, Tanytarsini average abundance was 4271 +/- 1135 S.E. m(-2) and 625 +/- 98 after litter exclusion. Biomass was 3.57 +/- 0.96 mg AFDM m(-2) before litter exclusion and 1.03 +/- 0.9 after exclusion. In contrast, Orthocladiinae abundance and biomass did not change because a psammanophilic chironomid, Lopescladius sp., and other Orthocladiinae genera did not decline significantly. Overall chironomid taxa richness and diversity did not change as a result of litter exclusion. However, Canonical Correspondence Analysis (CCA) of genus-level biomass did show a clear separation between the litter exclusion stream and a reference stream. Separation of taxa between the two streams was due to differences in fine (r(2) = 0.39) and coarse (r(2) = 0.36) organic matter standing stocks and the proportion of small inorganic substrates (r(2) = 0.39) present within a sample. As organic matter declined in the litter exclusion stream, overall chironomid biomass declined and the chironomid community assemblage changed. Tanytarsini were replaced by Orthocladiinae in the litter exclusion stream because they were better able to live and feed on biofilm associated with inorganic substrates.

Both theoretical and statistical examination of experimental data supports a square root transformation of lignin to predict microfibril angle. The experimental material used came from 10 longleaf pine (Pinus palustris) trees. Klason lignin (n=70), microfibril angle (n=70), and extractives (n=100) were measured and reported at different ring numbers and heights. All three traits were strongly influenced by ring age from pith while microfibril angle and extractives exhibited more of a height effect than lignin. As such, the multivariate response of the three traits were different in the axial direction than the radial direction supporting that care needs to be taken when defining juvenile wood within the tree. The root mean square error of calibration (RMSEC) for microfibril angle of the theoretical model (RMSEC 9.8) was almost as low as the least squares regression model (RMSEC 9.35). Microfibril angle calibrations were also built from NIR absorbance and showed a strong likeness to theoretical and experimental models (RMSEC = 9.0). As a result, theoretical and experimental work provided evidence that lignin content played a significant role in how NIR absorbance relates to microfibril angle. Additionally, the large variation in extractives content coupled with sampling procedure proved important when developing NIR based calibration equations for lignin and microfibril angle.

The spatial resolution of the NIR measurements has generally been limited to sections 10 mm wide and as a consequence the estimation of wood properties of individual rings or within rings has not been possible. Many different NIR instruments can be used to collect NIR spectra from the surface of radial strips at relatively high spatial resolution and the purpose of this study was to compare wood property calibrations obtained using NIR spectra collected in 5 mm and 2 mm sections with several different NIR instruments. We found that calibrations based on spectra collected in 5 mm sections had good statistics, with those based on the Bruker Vector 22/N spectrometer the strongest. Of the three properties examined (density, microfibril angle and stiffness), density had the weakest statistics. When the spatial resolution was decreased to 2 mm, calibration and prediction statistics were weaker than those at 5 mm. RPDp's were relatively low with the highest being 1.76 for predicted stiffness based on NIR spectra obtained using the ASD Field Spec Pro spectrometer. Based on the low RPDp's, we conclude that none of the instruments examined were suitable for scanning radial strips at a spatial resolution of 2 mm.

Roughness measurements of root mean-squared height (h(rms)) of the same surface can vary depending on the measuring instrument and how the data are processed. This letter addresses the error in h(rms) associated with instrument bias and instrument deployment issues such as number and length of measurement transects. It was found that at least 20 transect measurements, 3 m in length, for study sites ranging from 3.5 to 1225 m(2) in size were necessary to get a consistent h(rms), measurement. Also, roughness heights of longer transect lengths were highly dependent on the method of detrending the transects. Finally, soil moisture was predicted by inverting the integral equation model using roughness heights taking into account instrument bias, number of measurements, and the detrending method. For common configurations of the Radarsat sensor and reasonable h(rms) values, error associated with measurement of h(rms) generally exceeded +/- 20% of soil-moisture prediction.

This research was conducted over Iowa and Illinois to classify corn and soybean crops. Multitemporal 8-day composite 250-meter-resolution surface reflectance product time series were used to generate the NDVI data, which were used to differential between corn and soybean crops in the U.S. Corn Belt. The results of the MODIS-based classification were compared with the Landsat-based classification for the 2-year period. The overall classification accuracy for Iowa was 82%, and for Illinois 75%. In conclusion, this method has been used successively during the 2002-2006 years to develop crop classifications and products for crop conditions and potential yield maps for Iowa and Illinois.

Validation programs for the Advanced Microwave Scanning Radiometer-E (AMSR-E) instrument on the Aqua satellite is currently ongoing. As part of the AMSR-E validation activities several networks of ground based in-situ soil moisture sensors were established. in research watersheds. These networks provide estimates of the average soil moisture over the watersheds and surrounding areas that approximate the size of the AMSR-E passive microwave footprint. Four watersheds in different vegetation/climate regions of the U.S. were selected. All instrumentation was installed prior to the launch of AMSR-E in 2002. There are now over five years of observations available. Quality control of the data has included short term field experiments at some of the watersheds to verify calibration and scaling. The National Aeronautics and Space Administration (NASA) and Japanese Aerospace Exploration Agency (JAXA) soil moisture products were compared to the network observations, along with an alternative algorithm. The results indicate that each algorithm has different performance statistics that depend upon the site. A positive outcome of the analysis is that it appears that the algorithms have the potential to perform within acceptable error bounds. Preliminary results indicate the single channel algorithm performs very well in all four watersheds. These results are not final because the products of both agencies are undergoing revisions.

Through numerical simulations by surface emission model - Advanced Integral Equation Model (AIEM), we found that bare surface emissivities at different frequencies can be well characterized by a linear function with parameters that are dependent on the pair of frequencies to be used. This makes it possible to minimize the surface emission signal and maximize the vegetation signal when using multi-frequency radiometer measurements. Using the radiative transfer model (omega-tau model), a linear relationship between the brightness temperatures observed at two adjacent radiometer frequencies can be derived. It can be shown that the microwave vegetation index derived by the intercept and slope of this linear function depends only on vegetation properties and can be derived from the dual-frequency and dual-polarization measurements. We will demonstrate the theoretical basis of this new microwave vegetation index and show comparisons of the microwave derived vegetation index with the optical sensor derived NDVI measurements.

The system, now called ComRAD for Combined Radar/Radiometer, can function as a ground-based instrument simulator for L band space missions such as Hydros, Aquarius, and SMOS. In late summer 2006 ComRAD was deployed to the field to begin a series of coordinated active/passive L band measurements over small stands of deciduous and coniferous trees in order to improve our understanding of the microwave properties of trees and their effect on soil moisture retrieval algorithms. This paper describes the preliminary measurements obtained at the start of a three-year planned field measurement effort.

However, the antenna size required to achieve an appropriate resolution from space has limited the development of spaceborne L-band radiometers. This problem can be addressed by interferometric technology called aperture synthesis. The Soil Moisture and Ocean Salinity (SMOS) mission will apply this technique to monitor global-scale surface parameters in the near future. The first airborne experiment using an aircraft prototype of this approach, the Two-Dimensional Synthetic Aperture Radiometer (2D-STAR), was performed in the Soil Moisture Experiment in 2003 (SMEX03). The L-band brightness temperature data acquired in Alabama by the 2D-STAR was compared with ground-based measurements of soil moisture and with C-band data collected by the Polarimetric Scanning Radiometer (PSR). Our results demonstrate a good response of the 2D-STAR brightness temperature to changes in surface wetness, both in agricultural and forest lands. The behavior of the horizontally polarized brightness temperature data with increasing view-angle over the forest area was noticeably different than over bare soil. The results from the comparison of 2D-STAR and PSR indicate a better response of the 2D-STAR to the surface wetness under both wet and dry conditions. Our results have important implications for the performance of the future SMOS mission.

An evaluation of FARSITE and FlamMap bushfire spread models developed by the Fire Sciences Laboratory at Missoula involved a comparison of fire simulator models over two Californian landscapes representing different terrain and vegetation regimes. The paper includes a discussion on the models, the assumptions and limitations resulting from their application, and also the assembly of data to build landscape files and model outputs over the two test areas. The spatial datasets used in this study are sourced from the USGS EROS Data Center's LANDFIRE database at 30-metre pixel resolution. Information about fuel which has been derived from satellite imagery, terrain modelling and biophysical and local field knowledge was used to build Anderson's 13 Fire Behavior Fuel Models (FBFM13) and Scott and Burgan's 40 Fire Behavior Fuel Models (FBFM40). These were ingested into the FARSITE fire growth simulation model and FlamMap fire potential simulator. The FBFM40 provides a better representation of fuel across the landscape, leading to an improvement in surface fire intensity prediction and increased precision in determining crown fire behaviour. The FARSITE/FlamMap were used to model fire behaviour, and WindWizard simulated wind speed and direction scenarios across the Woodacre and Glen Ellen regions near San Francisco, California. FARSITE and FlamMap are two separate fire simulation models that use the same input datasets (vegetation/ground cover type, crown stand height, crown base height, crown bulk density, temperature, humidity, precipitation, slope, aspect, elevation, wind speed and direction). In this study, the actual fire perimeters were not available to compare the overestimated and underestimated fire growth perimeters/areas after and before using gridded wind data into the fire simulation. However, previous studies [1] demonstrate that incorporation of gridded wind data clearly improves prediction of fire growth perimeters. The preliminary evaluation of FARSITE/FlamMap simulations appropriately predicts fire growth process and assesses resources at risk, suggesting the need for further experiments in areas of different terrain and vegetation, and with varied weather conditions. In future research, it is proposed to evaluate how these models compare with existing Australian fire models by using the example of recent Australian wildfire events.

The earliest surviving European blackberry (R. fruticosus L. sp. agg.) image is found on folio 83 in the Juliana Anicia Codex (Codex Vindobonensis) of 512 CE which contains copies of several older texts including an illuminated, illustrated, partial alphabetical recension of De Materia Medica (English: On Medical Matters) written in the first century by Pedanius Dioscorides. Comparisons are made with other blackberry images from later Dioscoridean recensions including the Codex Neapolitanus folio 32 (7(th) century CE), Morgan folio 25 (10(th) century CE), Grecian 2179 folio 82b (8(th) century), and Arab 2850 folio 19 (13(th) century CE). Rubus images from the Medieval Period include the recensions of Apuleius Platonicus: Leyden Apuleius (600 CE), Leech Book of Bald (920) and Bodley 130 (1120 CE). Renaissance images from the 16(th) century include Rubus paintings from a prayer book, Horae ad Usum Romanum (Grandes Heures d'Anne de Bretagne) ca. 1503 to 1508, drawings by Leonardo da Vinci (1508 to 1510), and a woodcut from De Historias Stirpium of Leonhart Fuchs (1542). Images from the ancients represented nature, but deteriorated to crude diagrammatic representations in the Medieval Period.

Hypocotyl tissue from zygotic embryo axis produced adventitious shoots when treated with either thidiazuron (TDZ, I mu M) or 6-benzylaminopurine (BA, 20 mu M). TDZ resulted in more than a threefold higher rate of shoot induction (a maximum of 24.2 shoots per explant) than BA (6.8 shoots). Our results also showed that the pretreatment of explants in the dark increased the number of shoots regenerated per explant by 82% and 36% with TDZ and BA, respectively. The elongation of hypocotyl tissue in the dark appears to be the primary cause of the increase. Comparable rates of rooting were achieved on the media supplemented with either indole-3-butyric acid (IBA, 84.3%) or 1-naphthalene-acetic acid (NAA, 87.4%) at 5 mu M. However, IBA was more efficient in promoting root and shoot development, resulting in a higher rate of establishment (93.5%) in the soil, compared to the rate with NAA (39.5%). Histological analysis showed the adventitious induction of the shoot buds originated from the cortex of the hypocotyl tissue. C1 USDA ARS, Western Reg Res Ctr, Albany, CA 94710 USA.

We examined leaf surfaces of 26 species representing 14 genera of C4 grasses. In all species, we found similarities between leaf surface microhair-like structures and Uredomycete teliospores. These bicellular structures produced hyphae and spores, confirming they were fungal, rather than plant tissue. The plant-fungus structural morphology was also observed in Bouteloua eriopoda plants regenerated from embryonic meristem cells. The conserved symbiosis between fungi and C4 grasses suggests a lichenous association with evolutionary significance. The structural integration of endosymbiotic fungi with cells and tissues offers novel and unexplored approaches to developing physiological, ecological, and systematic models of C4 grasses.

Consequently, research and development efforts to engineer properties of dextranases to specific conditions of industrial processes have not occurred and are not expected soon. This book chapter highlights the difficulties associated with the practical application of dextranases, that are sometimes applied to hydrolyze dextran in sugar manufacture when bacterial deterioration of sugarcane or sugarbeet has occurred. Less than optimum application existed because of confusion about where to add the dextranase in the factory/refinery and which commercial dextranase to use. The wide variation in activity of commercially available dextranases in the U.S., and a standardized titration method to measure activities at the factory are discussed. Optimization by applying "concentrated" dextranase as a working solution to heated juice is described. Promising short-term technologies to further improve industrial dextranase applications are discussed, as well as the long-term outlook.

Unlike traditional oil extraction methods, these new bioprocesses are performed without the use of presses and organic solvents. Beginning with olive oil in the pre-Biblical era, oil has been obtained from oil-rich plant materials. The large variations in cell wall ultrastructure and chemical composition (varying proportions of cellulose, hemicellulose, and pectin) of oil-rich plant materials have posed a challenge for the development of aqueous enzymatic oil extraction strategies. For most oil-rich plant materials, three types of enzymes (cellulases, proteases or pectinases) have proven to be most effective for the aqueous enzymatic oil extraction. Although the high cost of enzymes is a major hurdle to the commercialization of aqueous enzymatic oil extraction methods, recent advances in enzyme production technology may soon make the processes economically viable.

However, two major shortcomings that impede acceptance by industry are expensive processing costs and slow reaction rates. Enzymatic bio-processing of cotton textiles with cellulase and pectinase enzyme processing solutions, under low energy, uniform sonication greatly improved the efficiency of the enzymes and significantly increased the overall reaction rates. Specific critical features of combined enzyme/ultrasound bio-processing are: a) cavitation effects that enhance the transport of enzyme macromolecules toward the substrate surface, b) the several hundred fold greater effect of cavitation in heterogeneous than homogeneous systems, and c) the maximum effects of cavitation at similar to 50 degrees C that are optimum temperature for most enzymatic reactions. Contrary to common belief, low intensity, uniform sonication does not damage or inactivate sensitive structures of enzyme protein macromolecules. Overall, under specific conditions, carefully controlled introduction of ultrasound energy during enzymatic bio-processing has an excellent potential for the intensification of a variety of technological processes that involve many types of industrial enzymes and substrates.

One aspect of enzymatic hydrolysis of saccharides could be a twisting distortion of the bonds between adjacent monosaccharide residues in carbohydrate substrates. If such twists are important, then new enzymes could be engineered that would increase the distortion for faster reaction. One way to learn if such distortion occurs is to survey existing crystalline carbohydrate-protein complexes. Unusual twists of linkages at the active site in an enzyme may result from catalysis. A related question is whether twisting of the linkage bonds increases the molecular potential energy. For the present work we have tracked the twisting in hundreds of protein-carbohydrate structures and used improved computer modeling of cellobiose to obtain energies. The largest apparent distortions were in similar molecules based on lactose.

To further add value to soybean oil, chemical and physical modifications, as well as additives, have been extensively used to change the oil characteristics and properties, broadening the potential industrial applications. Heat treatments such as heat-bodying have been implemented to change soybean oil properties, but no research has studied the effects of microwave-irradiation on soybean oil structure. and properties. Soybean oil (SBO) was heat-bodied (HB) or microwave-irradiated (MI). HB and MI (200-250 degrees C for 20-60 min) oil had similar Gardner bubble viscosity (B-C range). SBO that was HB or MI had increased viscosity compared with untreated SBO. H-1 NMR analysis showed no oxidation occurred for all treatments. However, HB and MI oil formed a cyclic ring structure with polymerization that most likely contributed to the increased viscosity. Pour point decreased from -9 degrees C for the untreated SBO, -15 degrees C for the HB, and -18 degrees C for the MI despite viscosity increases. Pour point anomaly is likely due to triacylglyceride cyclic ring formation. Pressurized DSC analysis showed higher oxidative stability for HB oil with even higher stability for MI oil. Compared with untreated SBO. HB and MI oil increased friction coefficient and decreased film percentage, whereas MI oil tended to leave larger wear scratches on the ball and disk during friction measurements. MI oil improved SBO cold-flow behavior, but reduced its potential as a lubricant. (C) 2006 Elsevier B.V. All rights reserved. C1 ARS, Plant Polymers Res Unit, USDA, NCAUR, Peoria, IL 61604 USA.

Morrison, Herb TI Flax-cotton fiber blends: Miniature spinning, gin processing, and dust potential SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE cotton; blends; dust; strength; flax; ginning AB Development of a flax (Linum usitatissimum L.) industry in North America is desired to supply a domestic source of clean, consistent quality textile fiber for blending with cotton. The objective of this work was to evaluate portions of traditional cotton gin equipment (extractor feeder and lint cleaner) and the "50-g cotton-spinning test (CST)" for flax. Dust was collected on an area sampler in an isolated card room to evaluate dust potential during textile pilot plant processing. Fibers retted by diverse means were cleaned on two separate portions of Continental Eagle's pilot plant cotton gin stand, the Super 96 Feeder and the 24D lint cleaner. Fibers separated and removed from flax stalks by these gin sections were compared against the standard 'unified line' processing technique of the USDA Flax Pilot Plant. Test yams were then made in a CST with cotton and flax blends to provide an indirect measurement of fiber properties that can be related to the retting and gin cleaning processes. The yarns were tested for strength and evenness. Flax fibers that displayed the most favorable properties in the CST were then spun in 23 kg lots in the pilot plant at the following cotton/flax blend ratios: 100/0, 75/25, 50/50, 25/75, and 20/80. With modifications, it appears that portions of a cotton gin stand are able to process adequately small samples of properly retted flax stalks. The CST with minor adjustments provides useful data for ranking and further large-scale flax processing. As expected, it appears that flax fiber can be successfully cleaned on a cotton processing line and that increasing the amount of flax generates additional dust. (C) 2006 Published by Elsevier B.V.

TI Starch-encapsulated, soy-based, ultraviolet-absorbing composites with feruloylated monoacyl- and diacylglycerol lipids SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE lipids; ferulic acid; starch-oil composites; steam jet cooking; sunscreen; ultraviolet absorption ID STEAM JET COOKING; FILMS AB Ferulic acid is a hydroxy cinnamic acid derivative found ubiquitously throughout the plant kingdom, is especially abundant in rice and corn bran, and possesses excellent ultraviolet (UV) and antioxidant properties. Ferulic acid was enzymatically incorporated into soybean oil to form feruloylated monoacyl- and diacylglycerols (FAG). The FAG possess the UV-absorbing and antioxidant properties of ferulic acid but are water insoluble and extremely lipophilic. These characteristics make FAG attractive in the cosmeceutical industry as an all-natural replacement for petroleum-based sunscreen active ingredients and antioxidants. The FAG were synthesized from the transesterification of soybean oil with ethyl ferulate catalyzed by the commercial lipase, Novozym 435 (Candida antartica lipase B). The FAG were encapsulated as microdroplets within a starch matrix via steam jet cooking (140 degrees C and 225 kPa). Up to 50% (w/w) of the feruloylated lipids was encapsulated into the starch matrix with the microdroplets ranging in size from 1 to 10 mu m. Transmittance and irradiance measurements of UV radiation (300-400 nm) through thin films of neat FAG (not manipulated after FAG synthesis) and starch-encapsulated FAG showed that the FAG retained its ultraviolet-absorbing efficacy after steam jet cooking. Furthermore, starch-encapsulation of the FAG was found to enhance the ultraviolet absorbance of the feruloylated lipids. When encapsulated at 50% (w/w) in the starch matrix, one-half of the coverage (mg/cm(2)) of FAG was required to block the same amount or more UV radiation as neat FAG. The starch-encapsulated FAG was formulated as an aqueous dispersion without the need for emulsifiers or surfactants. The dispersions were drum dried to a powder and shown to be easily reconstituted into water dispersions without the loss of ultraviolet-absorbing efficacy. (C) 2006 Elsevier B.V. All rights reserved.

Understanding the minimum temperatures for germination and seedling growth is important for determining potential areas for lesquerella production. The objectives of this study were to determine the cardinal temperatures for germination and seedling growth, and to screen ecotypes for germination and growth characteristics. A temperature gradient table arrangement was used to observe seed germination over a range of temperatures, and time to germination and shoot appearance. Times to 5 mm root length and 5 mm shoot length were also measured to assess cardinal temperatures for seedling survival and growth. Two different species were examined, L. fendleri and a species we refer to as 'L pallida aff.' because it differed from typical L. pallida plants in chromosome number and in oil quality. We concluded that both germination and growth of L. pallida aff. occurred fastest at 22 degrees C, whereas L. fendleri germinated earlier at 18 degrees C, but grew faster at 22 degrees C. L. pallida aff. also had lower germination than L. fendleri over the range studied. Non-dormant seeds of improved lines of L. fendleri had better performance at temperatures above 22 degrees C than did unimproved accessions. Lines of L. fendleri selected for high oil content and salt tolerance had similar temperature requirements for germination except for improved line WCL-LO3, the current line being used in production. This line had optimal temperatures 6 degrees C higher for germination and growth than the other improved lines. Accessions of L. fendleri collected from elevations above 2000 m performed better at warmer temperatures, whereas those collected from elevations below 2000 m tended to perform better at cooler temperatures. Dormant seeds of L. fendleri germinated more quickly at low temperatures and had lower base (<3 degrees C) and optimal (22 degrees C) temperatures than non-dormant seeds (>7 degrees C and 28 degrees C, respectively). We speculate that this partial dormancy trait allows populations of L. fendleri to exploit a wider range of temperature conditions in the wild in order to thrive in extreme environments.

Typical plasticizing agents that improve processability have a negative impact on physical properties at elevated humidities. Continued efforts must be employed to discover improved plasticizers. Carboxylic acids having more than one carboxylic acid moiety have been evaluated in zein melt formulations produced in a torque rheometer. These reagents were effective plasticizers for zein, lowering zein viscosity, and delaying the onset of rapid viscosity increase. These reagents altered viscosity differently than the traditional plasticizers such as triethylene glycol. These additives also lowered the tensile strength (TS) of zein formulations at 50% RH. Surprisingly, TS at 70% RH was higher than that at 50% RH at elevated levels of these additives. NMR analysis of Soxhlet extracted samples showed that these multivalent carboxylic acids do not cross-link the zein under the reaction conditions employed. (C) 2006 Elsevier B.V. All rights reserved.

TI Wild annual Helianthus anomalus and H-deserticola for improving oil content and quality in sunflower SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE sunflower; oilseed; oleic acid; linoleic acid; palmitic acid; stearic acid ID FATTY-ACID-COMPOSITION; SEED OIL; ASTERACEAE; SELECTION; ACHENES AB Within the past decade, the desire for alternative sources of fuels, chemicals, and other industrial materials has received increased attention. Sunflower (Helianthus annuus L.) oil has the potential to be improved for nutritional and industrial purposes through selection and breeding. The narrow genetic base of cultivated sunflower has been broadened by the infusion of genes from wild species, resulting in a continuous improvement in agronomic traits. The genus Helianthus is comprised of 51 species and 19 subspecies with 14 annual and 37 perennial species. Interest in using wild species in breeding programs has increased, but concerns about the introduction of low oil concentration and quality from the wild species persist. Two annual desert species, Helianthus anomalus Blake and H. deserticola Heiser, are excellent candidates for increasing oil concentration and enhancing quality based on their adaptation to desert environments. The objective of this study was to collect achenes of H. anomalus and H. deserticola from the desert southwest USA and assess their potential for improving oil concentration and quality in cultivated sunflower. The sunflower collection took place from 16 to 23 September 2000 and covered a distance of 4100 km in three states: Utah, Arizona, and Nevada. The only H. deserticola population collected had an average oil concentration of 330 g/kg, whereas the two populations of H. anomalus had an oil concentration of 430 and 460 g/kg, the highest concentration recorded in any wild sunflower species. The linoleic fatty acid concentration in the oil of H. anomalus populations was uncharacteristically high for a desert environment, approaching 700 g/kg. A linoleic acid concentration of 540 g/kg in H. deserticola was more typical for a desert environment. H. anomalus has the largest achenes and the highest oil concentration of any wild sunflower species, and the same chromosome number (n = 17) as cultivated sunflower. These features will facilitate the introduction of genes from this wild annual progenitor into cultivated sunflower. The lower saturated fatty acid profile in this species is also a desirable trait offering the potential to reduce saturated fatty acids in cultivated sunflower. Further research will be needed to determine the inheritance of the fatty acids and oil concentration.

In response to higher energy prices, along with government incentives, the fledgling biodiesel industry is beginning to grow at a rapid pace. However, there are clearly economic limits to biodiesel's growth potential and questions are being raised about the future role biodiesel can play in reducing our energy dependence Since vegetable oils and animal fats will continue to be used primarily for food products, biodiesel production can only supply a small portion of our fuel needs. To further increase biodiesel production, we will need to develop new sources of feedstock and develop new technologies to convert a broader spectrum of feedstocks.

TI Low parasite loads accompany the invading population of the bumblebee, Bombus terrestris in Tasmania SO INSECTES SOCIAUX LA English DT Article DE founder population; introduction; genetic diversity; mites; Kuzinia ID BIOLOGICAL-CONTROL INTRODUCTIONS; FLIES CONOPIDAE; APIDAE; HYMENOPTERA; BEE; VIRULENCE; CONSEQUENCES; EUSOCIALITY; POLYANDRY; CONSTANCY AB In its native Europe, the bumblebee, Bombus terrestris (L.) has co-evolved with a large array of parasites whose numbers are negatively linked to the genetic diversity of the colony. In Tasmania B. terrestris was first detected in 1992 and has since spread over much of the state. In order to understand the bee's invasive success and as part of a wider study into the genetic diversity of bumblebees across Tasmania, we screened bees for co-invasions of ectoparasitic and endoparasitic mites, nematodes and micro-organisms, and searched their nests for brood parasites. The only bee parasite detected was the relatively benign acarid mite Kuzinia laevis (Dujardin) whose numbers per bee did not vary according to region. Nests supported no brood parasites, but did contain the pollen-feeding life stages of K. laevis. Upon summer-autumn collected drones and queens, mites were present on over 80% of bees, averaged ca. 350-400 per bee and were more abundant on younger bees. Nest searching spring queens had similar mite numbers to those collected in summer-autumn but mite numbers dropped significantly once spring queens began foraging for pollen. The average number of mites per queen bee was over 30 fold greater than that reported in Europe. Mite incidence and mite numbers were significantly lower on worker bees than drones or queens, being present on just 51% of bees and averaging 38 mites per bee. Our reported incidence of worker bee parasitism by this mite is 5-50 times higher than reported in Europe. That only one parasite species co-invaded Tasmania supports the notion that a small number of queens founded the Tasmanian population. However, it is clearly evident that both the bee in the absence of parasites, and the mite have been extraordinarily successful invaders.

This study focuses on determining the colony structure of A. collate, specifically searching for evidence of polydomy or independence. We surveyed and observed nests in the field, and performed foraging bioassays and dissected nests in the laboratory. We determined the size and contents of nests in field populations. Nests found near other nests were not statistically different in size compared to nests found alone. There was also no statistical difference between near and lone nests regarding the presence of a queen in the nest. Most nests contained one queen with brood and workers, regardless of their proximity to other nests. Observations also were made of foraging and trail-marking behaviors. Foraging activity observed in the field revealed that workers left the nest area and followed trails upwards into the canopy, but they did not interact with foragers from other nearby nests. In a laboratory foraging arena, foragers marked a trail to a food source by dragging the gaster. Bioassays showed that A. collare workers preferred their own foraging trails, but not those of other conspecific colonies. All results suggest that each nest represents an independent colony, supporting a previous report that nests found in close proximity do not constitute a polydomous colony.

Though cementation is usually reduced by tillage, soil amendments can offer a more permanent solution if they develop aggregation. To increase aggregation, we amended 450 g of a Norfolk soil blend of 90% E horizon (the hard layer) and 10% Ap horizon with 0 or 6.44 g kg(-1) ground wheat (Triticum aestivum L.) residue and 0, 30, or 120 mg kg(-1) polyacrylamide (PAM, 12 x 10(6) Da anionic, linear, and 35% charge density). During a 60-d incubation, parameters measured included water added to maintain 10% soil moisture, soil strength, bulk density, and aggregation. Data were analyzed using a cost-benefit approach with normalized fuzzy logic indicators. Analyses included building normalized decision matrices, calculating weighting vectors, ranking alternatives, and defining the best alternatives. When only physical parameters were analyzed using fuzzy logic indicators, addition of wheat residue with 30 mg kg(-1) PAM proved to be the best alternative whereas wheat residue with 120 mg kg(-1) PAM had been selected as the best alternative with analysis of variance because it did not simultaneously analyze all variables. When both physical and economic parameters were included, the best alternative was the treatment with wheat residue and 120 mg kg(-1) PAM. When using fuzzy logic, judgment of the user was needed to determine which parameters to include and how to weight them.

Accordingly, biocides intended for indoor applications must be non-toxic, non-volatile, odourless, hypoallergenic, and able to provide long-term protection under conditions of high humidity. Multi-component biocide systems were tested in American Wood-Preservers' Association soil block tests for inhibition of brown-rot and white-rot decay fungi and American Society for Testing and Materials standard tests for inhibition of mould fungi and termites. Multi-component systems combining a borate base supplemented with either 0.1% azole or 0.5% thujaplicin, performed well against the two brown-rot fungi Postia placenta and Gloeophyllum trabeum; the white-rot fungus Coriolus versicolor; the three mould fungi Aspergillus niger, Penicillium chrysogenum, and Trichoderma viride; and the subterranean termite Reticulitermes flavipes (Kollar). It was concluded that for interior applications borate-based multi-component biocide systems can protect wood from decay fungi, Mould fungi, and termites, and that a system containing thiabendazole provided protection at a lower retention than the other biocides in this study. Synergy was observed between the borate base and voriconazole in inhibition of mould. Published by Elsevier Ltd. C1 USDA, Forest Prod Lab, Forest Serv, Madison, WI 53726 USA.

FSTs were placed in Petri dishes containing a food Source soaked in one of these extracts/compounds. The numbers of three flagellated protozoan species that inhabit the FST hindgut (Pseudotrichonympha grassii, Spirotrichonympha leidyi and Holomastigotoides hartmanni) and spirochaetes were counted over a defined period and analysed for changes in abundance. The results indicated that the neem extract was capable of reducing the population of P. grassii and spirochaetes. Exposure to this extract resulted in significant FST mortality. However, gleditschia extract and capsaicin did not reduce the FST gut microbial population at the concentrations used in this study. (c) 2006 Elsevier Ltd. All rights reserved.

Case herds were those with presence of cattle with clinical signs of FMD and that tested positive for FMD virus during the epidemic of 2002 (n = 39). Control farms (n = 78) were selected randomly from a list of farms without a history of FMD. All study farms were visited, and managers were interviewed to complete an epidemiologic questionnaire. Feedlot operations, purchase of livestock at markets, and close proximity to markets or slaughter facilities were identified as risk factors for FMD (P <= 0.01). In addition to systematic vaccination of the national herd, we recommend allocation of funds for ring-vaccination of cattle herds in close proximity to markets or slaughter facilities, and to enforce movement of vaccinated-cattle only to help control and prevent new epidemics of FMD.

The swine has been used as a major mammalian model for human studies because of the similarity in size and physiology, and in organ development and disease progression. The pig model allows for deliberately timed studies, imaging of internal vessels and organs using standard human technologies, and collection of repeated peripheral samples and, at kill, detailed mucosal tissues. The ability to use pigs from the same litter, or cloned or transgenic pigs, facilitates comparative analyses and genetic mapping. The availability of numerous well defined cell lines, representing a broad range of tissues, further facilitates testing of gene expression, drug susceptibility, etc. Thus the pig is an excellent biomedical model for humans. For genomic applications it is an asset that the pig genome has high sequence and chromosome structure homology with humans. With the swine genome sequence now well advanced there are improving genetic and proteomic tools for these comparative analyses. The review will discuss some of the genomic approaches used to probe these models. The review will highlight genomic studies of melanoma and of infectious disease resistance, discussing issues to consider in designing such studies. It will end with a short discussion of the potential for genomic approaches to develop new alternatives for control of the most economically important disease of pigs, porcine reproductive and respiratory syndrome ( PRRS), and the potential for applying knowledge gained with this virus for human viral infectious disease studies.

TI Identifying the future needs for long-term USDA efforts in agricultural animal genomics SO INTERNATIONAL JOURNAL OF BIOLOGICAL SCIENCES LA English DT Review DE animal genomics; sequencing; functional genomics; bioinformatics ID CHICKEN; TRAITS; CATTLE; MAP AB Agricultural animal research has been immensely successful over the past century in developing technology and methodologies that have dramatically enhanced production efficiency of the beef, dairy, swine, poultry, sheep, and aquaculture industries. In the past two decades, molecular biology has changed the face of agricultural animal research, primarily in the arena of genomics and the relatively new offshoot areas of functional genomics, proteomics, transcriptomics, metabolomics and metagenomics. Publication of genetic and physical genome maps in the past 15 years has given rise to the possibility of being able finally to understand the molecular nature of the genetic component of phenotypic variation. While quantitative geneticists have been remarkably successful in improving production traits, genomic technology holds potential for being able to lead to more accurate and rapid animal improvement, especially for phenotypic traits that are difficult to measure. Recently, the agricultural research community has been able to capitalize on the infrastructure built by the human genome project by sequencing two of the major livestock genomes (Gallus domesticus and Bos Taurus). The 2005 calendar year is truly unprecedented in the history of agricultural animal research since draft genome sequences were completed for chickens and cattle. In addition, sequencing the swine and equine genome was initiated in early 2006. We now have in place a powerful toolbox for understanding the genetic variation underlying economically important and complex phenotypes. Over the past few years, new challenges have emerged for animal agriculture. Enhancements in production efficiency have not come without some negative side effects on animal well-being and longevity in production environments, including losses in reproductive efficiency, increased stress susceptibility, increased animal waste issues, and increased susceptibility to animal metabolic and infectious diseases. When considered in concert with societal concerns in the areas of natural resource conservation and protection, animal welfare, and food safety, it is clear that publicly supported agricultural research must be focused on enhancing the functionality and well-being of livestock and poultry in environmentally neutral production systems in the future. Realizing the great potential for animal genomics to address these and other issues, a workshop was convened by the U. S. Department of Agriculture (USDA) in Washington, DC in September of 2004. The workshop was entitled "Charting the Road Map for Long Term USDA Efforts in Agricultural Animal Genomics". This paper summarizes the proceedings of the workshop and the resulting recommendations. The need for a cohesive, comprehensive long-term plan for all of USDA's research efforts in animal genomics was evident at the workshop, requiring further integration of the efforts of the USDA's Cooperative State Research, Education, and Extension Service (CSREES) and the USDA's Agricultural Research Service (ARS) to achieve the greatest return on investment.

Samples (75-125 broilers per site) were collected during five plant visits from August to October of 2004. Arcobacter was recovered from pre-scald carcasses more frequently (96.8%) than from pre-chill (61.3%) and post-chill carcasses (9.6%). Campylobacter was isolated from 92% of pre-scald carcasses, 100% of pre-chill carcasses, and 52% of post-chill carcasses. In total, Arcobacter was isolated from 55.1% (179 of 325), while Campylobacter was isolated from 78.5% (255 of 325) of the carcasses from the three collection sites. For Arcobacter identification, a species-specific multiplex PCR showed that A. butzleri was the most prevalent species (79.1%) followed by A. cryaerophilus 1B (18.6%). A. cryaerophilus 1A was found at low levels (2.3%). PCR identified the most common Campylobacter species as C. jejuni (87.6%) followed by C. coli (12.4%). Overall, significant contamination of broiler carcasses by Arcobacter was observed, although less than that found for Campylobacter. From pre-scald to post-chill, a far greater reduction in Arcobaeter numbers was observed than for Campylobacter. Our results for Arcobacter, obtained from the same environment as the closely related pathogen Campylobacter, will aid in the development of control measures for this emerging pathogen.

Five L. monocytogenes serogroups were identified. Of the 167 isolates 68 (41%) belonged to serogroup 1/2b, 3b; 53 (32%) belonged to serogroup 4b, 4d, 4e; 43 (26%) belonged to serogroup 1/2a, 3a; 2 (1.2%) belonged to serogroup 1/2c, 3c; and 1 (0.6%) belonged to serogroup 4a, 4c. PFGE generated 120 patterns which correlated well with PCR serogrouping. Most L. monoc.lltogenes isolates were resistant to sulfonamide (73%) and some were resistant to tetracycline (8.4%) and ciprofloxacin (1.8%). Tetracycline resistance was conjugatively transferable and the tet(M) gene was identified in 14 tetracycline-resistant isolates as well as their transconjugants. These findings indicate that L. monocytogenes present in food were diverse, and that resistance to one or more antibiotics among these isolates was common. In addition, the presence of potential serotype 4b in all food categories is of public health concern, as serotype 4b has been the serotype most frequently associated with human listeriosis.

Optimizing this process will result in lower production costs and increased product quality. Moisture transfer in heterogeneous materials, such as foods, is a complex process where more than one mechanism may occur. After over eighty years of applying Fick's Second Law diffusion equation to drying of foods, there are still wide variability in reported diffusion coefficients. This article reviews moisture transfer mechanisms, models developed to predict moisture transfer, measurement of effective moisture diffusivity, which is the most common parameter used in predicting moisture transfer, and advanced measurements of moisture profiles to quantify and validate predictive models.

From 1990 through 2004, 57 702 bird collisions with aircraft were reported within the USA to the US Federal Aviation Administration. Approximately 82% of the strikes occur below 305 m height above ground level; therefore bird deterrents on airfields that reduce the quality of the birds' habitat are critical to safe airport operation. One management approach is to reduce perching sites within the airport premises. We tested two anti-perching devices (Birdwire (TM) and BirdBlox (TM)) in an aviary setting. As an ancillary test, we determined which wire in a standard three-strand security array was preferred by blackbirds and starlings. Red-winged blackbirds (Agelaius phoeniceus), brown-headed cowbirds (Molothrus ater), and European starlings (Sturnus vulgaris) were deterred from sitting on a perch when anti-perching wire was installed 5 cm above the perch. These same species preferred the top wire of the three-wire security array. Red-winged blackbirds, common grackles (Quiscalus quiscula), brown-headed cowbirds, European starlings, and rock pigeons (Columba livia) were deterred from perches protected by BirdBlox (TM). Because our tests were conducted in a captive situation, we recommend field testing the products to determine if bird use of airport structures may be reduced in an operational setting.

Only 4 (11%), 2 (8%), and 2 (8%) of isolates from each of the environments, respectively, were able to tolerate 200 mg Cr (VI) L-1. When these eight isolates were tested for their ability to tolerate other metals or to reduce chromate, they were shown to also be resistant to Zn, Mn, and Pb, and to display different degrees of chromate reduction (28% to 95%) under aerobic conditions. The isolates with the higher chromate reduction rates from 42% to 95%, (RAI, RA2, RA3, RA5, RA 7, and RA8) were genetically diverse according to RAPD analysis using four different primers. Bacterial isolates RA 1, RA2, RA3, RA5, and RA8 had 16 S rRNA gene sequences that were most similar to Pseudomonas diminuta, Brevundimonas diminuta, Nitrobacteria irancium, Ochrobactrum anthropi, and Bacillus cereus, respectively. Water hyacinth inoculated with RA5 and RA8 increased Mn accumulation in roots by 2.4- and 1.2-fold, respectively, compared to uninoculated controls. The highest concentrations of Cr (0.4 g kg(-1)) and Zn (0.18 g kg(-1)) were accumulated in aerial portions of water hyacinth inoculated with RA3. Plants inoculated with RAI, RA2, RA3, RA5, RA 7, and RA8 had 7-, 11-, 24-, 29-, 35-, and 21-fold, respectively, higher Cr concentrations in roots compared to the control. These bacterial isolates are potential candidates in phytoremediation for chromium removal. C1 Genet Engn & Biotechnol Res Inst, Environm Biotechnol Dept, Mubarak City Sci Res, Alexandria, Egypt.

We irrigated Populus (DN17, DN182, DN34, NM2, NM6) and Salix (94003, 94012, S287, S566, SX61) genotypes planted in large soil-filled containers with landfill leachate or municipal water and tested for differences in inorganic element concentrations (P, K, Ca, Mg, S, Zn, B, Mn, Fe, Cu, Al, Na, and Cl) in the leaves, stems, and roots. Trees were irrigated with leachate or water during the final 12 wk of the 18-wk study. Genotype-specific uptake existed. For genera, tissue concentrations exhibited four responses. First, Populus had the greatest uptake of P, K, S, Cu, and Cl. Second, Salix exhibited the greatest uptake of Zn, B, Fe, and Al. Third, Salix had greater concentrations of Ca and Mg in leaves, while Populus had greater concentrations in stems and roots. Fourth, Populus had greater concentrations of Mn and Na in leaves and stems, while Salix had greater concentrations in roots. Populus deltoides x P. nigra clones exhibited better overall phytoremediation than the P. nigra x P. maximowiczii genotypes tested. Phytoremediation for S. purpurea clones 94003 and 94012 was generally less than for other Salix genotypes. Overall, concentrations of elements in the leaves, stems, and roots corroborated those in the plant-sciences literature. Uptake was dependent upon the specific genotype for most elements. Our results corroborated the need for further testing and selecting of specific clones for various phytoremediation needs, while providing a baseline for future researchers developing additional studies and resource managers conducting on-site remediation.

Populus (DN17, DN182, DN34, NM2, and NM6) and Salix (94003, 94012, S287, S566, and SX61) genotypes were irrigated with landfill leachate or municipal water and tested for differences in 1) element concentrations (P, K, Ca, Mg, S, Zn, B, Mn, Fe, Cu, Al, and Na) of a topsoil layer and a layer of sand in tanks with a cover crop of trees or no trees and 2) height, diameter, volume, and dry mass of leaves, stems, and roots. Trees were irrigated with leachate or water during the final 12 wk of the 18-wk study. Differences in most soil element concentrations were negligible (P > 0.05) for irrigation treatments and cover main effects. Phosphorous, K, Mg, S, Zn, Mn, Fe, and Al concentrations were greater in topsoil than sand (P = 0.0011 for Mg; P < 0.0001 for others). There was broad variation between genera and among clones for all growth traits. The treatment x clone interaction governed height, volume, and root dry mass, with (94012, SX61), (NM2, S566, SX61), and (S287, S566) exhibiting the greatest levels, respectively, following leachate application. Given the broad amount of variability among and within these genera, there is great potential for the identification and selection of specific genotypes with a combination of elevated phytoremediation capabilities and tree yield. From a practical standpoint, these results may be used as a baseline for the development of future remediation systems.

A common protocol for such efforts has been to utilize a limited number of readily-available genotypes with decades of deployment in other applications, such as fiber or windbreaks. However, it may be possible to increase phytoremediation success with proper genotypic screening and selection, followed by the field establishment of clones that exhibited favorable potential for clean-up of specific contaminants. There is an overwhelming need for testing and subsequent deployment of diverse Populus and Salix genotypes, given current availability of clonal material and the inherent genetic variation among and within these genera. Therefore, we detail phyto-recurrent selection, a method that consists of revising and combining crop and tree improvement protocols to meet the objective of utilizing superior Populus and Salix clones for remediation applications. Although such information is lacking for environmental clean-up technologies, centuries of plant selection success in agronomy, horticulture, and forestry validate the need for similar approaches in phytoremediation. We bridge the gap between these disciplines by describing project development, clone selection, tree establishment, and evaluation of success metrics in the context of their importance to utilizing trees for phytoremediation.

Poplar clones were irrigated during three cycles of phyto-recurrent selection to test whether genotypes responded differently to leachate and water, and to test whether the methodology had merit as a tool for plant selection during remediation. Fifteen below- and above-ground traits were evaluated. Twenty-five cloneswere tested in cycle 1, while the best 12 genotypes were evaluated in cycles 2 and 3. Eight cloneswere selected and subsequently tested in an in situ landfill study (cycle 4). Results from cycles 1, 2, and 3 are presented here. Overall, clones responded differently to irrigation treatments, with certain genotypes exhibiting better below-and above-ground growth with water than leachate. However, growth was greater with leachate irrigation for some clones. In addition, differences between treatments within clones decreased with days after planting (DAP). There were no treatment differences for number of leaves, height, and root length at the end of cycle 2 (45 DAP) or cycle 3 (30 DAP). These results detail the extensive variation in clonal responses to leachate irrigation, along with the need and efficacy of using phyto-recurrent selection to choose superior genotypes.

TI Differentiation of semi-arid vegetation types based on multi-angular observations from MISR and MODIS SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID REFLECTANCE AB Mapping accurately vegetation type is one of the main challenges for monitoring arid and semi-arid grasslands with remote sensing. The multi-angle approach has been demonstrated to be useful for mapping vegetation types in deserts. The current paper presents a study on the use of directional reflectance derived from two sensor systems, using two different models to analyse the data and two different classifiers as a means of mapping vegetation types. The multiangle imaging spectroradiometer (MISR) and the moderate resolution imaging spectroradiometer (MODIS) provide multi-spectral and angular, off-nadir observations. In this study, we demonstrate that reflectance from MISR observations and reflectance anisotropy patterns derived from MODIS observations are capable of working together to increase classification accuracy. The patterns are described by parameters of the modified Rahman-Pinty-Verstraete and the RossThin-LiSparseMODIS bidirectional reflectance distribution function (BRDF) models. The anisotropy patterns derived from MODIS observations are highly complementary to reflectance derived from radiances observed by MISR. Support vector machine algorithms exploit the information carried by the same data sets more effectively than the maximum likelihood classifier.

TI Production of Landsat ETM plus reference imagery of burned areas within Southern African savannahs: comparison of methods and application to MODIS SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID FIRE SEVERITY; TRACE GASES; VEGETATION INDEXES; SPECTRAL INDEXES; SCAR DETECTION; SATELLITE DATA; AVHRR; CLASSIFICATION; REFLECTANCE; FORESTS AB Accurate production of regional burned area maps are necessary to reduce uncertainty in emission estimates from African savannah fires. Numerous methods have been developed that map burned and unburned surfaces. These methods are typically applied to coarse spatial resolution (1 km) data to produce regional estimates of the area burned, while higher spatial resolution (< 30 m) data are used to assess their accuracy with little regard to the accuracy of the higher spatial resolution reference data. In this study we aimed to investigate whether Landsat Enhanced Thematic Mapper (ETM+)- derived reference imagery can be more accurately produced using such spectrally informed methods. The efficacy of several spectral index methods to discriminate between burned and unburned surfaces over a series of spatial scales (ground, IKONOS, Landsat ETM+ and data from the MOderate Resolution Imaging Spectrometer, MODIS) were evaluated. The optimal Landsat ETM+ reference image of burned area was achieved using a charcoal fraction map derived by linear spectral unmixing (k=1.00, a=99.5%), where pixels were defined as burnt if the charcoal fraction per pixel exceeded 50%. Comparison of coincident Landsat ETM+ and IKONOS burned area maps of a neighbouring region in Mongu (Zambia) indicated that the charcoal fraction map method overestimated the area burned by 1.6%. This method was, however, unstable, with the optimal fixed threshold occurring at > 65% at the MODIS scale, presumably because of the decrease in signal- to- noise ratio as compared to the Landsat scale. At the MODIS scale the Mid- Infrared Bispectral Index (MIRBI) using a fixed threshold of > 1.75 was determined to be the optimal regional burned area mapping index (slope=0.99, r(2) = 0.95, SE=61.40, y=Landsat burned area, x=MODIS burned area). Application of MIRBI to the entire MODIS temporal series measured the burned area as 10 267 km(2) during the 2001 fire season. The char fraction map and the MIRBI methodologies, which both produced reasonable burned area maps within southern African savannah environments, should also be evaluated in woodland and forested environments.

TI A derivation of roughness correlation length for parameterizing radar backscatter models SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID SOIL-MOISTURE; SURFACE-ROUGHNESS AB Surface roughness is a key parameter of radar backscatter models designed to retrieve surface soil moisture (theta(S)) information from radar images. This work offers a theory-based approach for estimating a key roughness parameter, termed the roughness correlation length (L-c). The Lc is the length in centimetres from a point on the ground to a short distance for which the heights of a rough surface are correlated with each other. The approach is based on the relation between L-c and h(RMS) as theorized by the Integral Equation Model (IEM). The hRMS is another roughness parameter, which is the root mean squared height variation of a rough surface. The relation is calibrated for a given site based on the radar backscatter of the site under dry soil conditions. When this relation is supplemented with the site specific measurements of hRMS, it is possible to produce estimates of L-c. The approach was validated with several radar images of the Walnut Gulch Experimental Watershed in southeast Arizona, USA. Results showed that the IEM performed well in reproducing satellite-based radar backscatter when this new derivation of L-c was used as input. This was a substantial improvement over the use of field measurements of L-c. This new approach also has advantages over empirical formulations for the estimation of Lc because it does not require field measurements of theta(S) for iterative calibration and it accounts for the very complex relation between L-c and hRMS found in heterogeneous landscapes. Finally, this new approach opens up the possibility of determining both roughness parameters without ancillary data based on the radar backscatter difference measured for two different incident angles.

A new, combined index derived from the Modified Chlorophyll Absorption Ratio Index (MCARI) and the second Modified Triangular Vegetation Index (MTVI2) in ratio obtained the best regression relationships with chlorophyll meter values (Minolta Soil Plant Analysis Development (SPAD) 502 chlorophyll meter) and flag leaf N. For SPAD, r(2) values ranged from 0.45 to 0.69 ( p < 0.01) for narrow bands and from 0.35 and 0.77 ( p < 0.01) for broad bands. For leaf N, r(2) values ranged from 0.41 to 0.68 ( p < 0.01) for narrow bands and 0.37 to 0.56 (p < 0.01) for broad bands. These results are sufficiently promising to suggest that MCARI/ MTVI2 employing broadband RapidEye (TM) data is useful for predicting wheat N status. C1 USDA ARS, CPCRC, Pendleton, OR 97810 USA.

TI Inferences of all-sky solar irradiance using Terra and Aqua MODIS satellite data SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID RESOLUTION IMAGING SPECTRORADIOMETER; WATER-VAPOR; SURFACE INSOLATION; RADIATIVE-TRANSFER; CLOUD; AEROSOL; MODEL; LAND; TEMPERATURE; VARIABILITY AB Solar irradiance is a key environmental control, and accurate spatial and temporal solar irradiance data are important for a wide range of applications related to energy and carbon cycling, weather prediction, and climate change. This study presents a satellite-based scheme for the retrieval of all-sky solar irradiance components, which links a physically based clear-sky model with a neural network version of a rigorous radiative transfer model. The scheme exploits the improved cloud characterization and retrieval capabilities of the MODerate resolution Imaging Spectroradiometer (MODIS) onboard the Terra and Aqua satellites, and employs a cloud motion tracking scheme for the production of hourly solar irradiance data throughout the day. The scheme was implemented for the Island of Zealand, Denmark (56 degrees N, 12 degrees E) and Southern Arizona, USA (31 degrees N, 110 degrees W) permitting model evaluation for two highly contrasting climates and cloud environments. Information on the atmospheric state was provided by MODIS data products and verifications against AErosol RObotic NETwork (AERONET) data demonstrated usefulness of MODIS aerosol optical depth and total precipitable water vapour retrievals for the delineation of spatial gradients. However, aerosol retrievals were significantly biased for the semi-arid region, and water-vapour retrievals were characterized by systematic deviations from the measurements. Hourly global solar irradiance data were retrieved with overall root mean square deviations of 11.5% (60 W m(-2)) and 26.6% (72 W m(-2)) for Southern Arizona and the Island of Zealand, respectively. For both regions, hourly satellite estimates were shown to be more reliable than pyranometer measurements from ground stations only 15 km away from the point of interest, which is comparable to the accuracy level obtainable from geostationary satellites with image acquisitions every 15-30 min. The proposed scheme is particularly useful for solar irradiance mapping in highlatitude regions as data from geostationary satellites experience a gradual degradation in spatial resolution and overall quality with latitude and become unusable above approximately 60 degrees latitude. However, in principle, the scheme can be applied anywhere on the globe, and a synergistic use of MODIS and geostationary satellite datasets may be envisaged for some applications.

TI Bidirectional effect on a spectral image sensor for in-field crop reflectance assessment SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID NITROGEN STATUS; CANOPY; MODEL; CORN; SUN AB Varying illumination geometry affects spectral measurements of a target reflectance and the intensity of solar radiation is the most important factor for in-field spectral measurements. This paper reports the effect of bidirectional electromagnetic radiation on an image-based reflectance sensor designed for plant nitrogen assessment. The results show the nonlinearity of reflectance as a function of the solar zenith angle. Ambient illumination was analysed and compensated for using fixed nadir-view positions of a solar radiometer and a 3-charge-coupled device (CCD) multispectral imaging sensor (MSIS). A compensation algorithm was developed to correct for the nonlinearity of both sensors. The compensated reflectance remained linearly consistent with varying the solar zenith angle throughout the daytime within a maximum standard deviation of 0.62% at all three (green, red and near-infrared) spectral channels, when testing with a 20% reflectance panel. The consistent reflectance was recovered under both sunny and cloudy conditions. C1 USDA, Agr Res Serv, No Plains Agr Res Lab, Sidney, MT 59270 USA.

TI MODIS tasselled cap: land cover characteristics expressed through transformed MODIS data SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID THEMATIC MAPPER DATA; PRODUCTS; INDEXES AB The tasselled cap concept is extended to Moderate Resolution Imaging Spectroradiometer (MODIS) Nadir BRDF-Adjusted Reflectance (NBAR, MOD43) data. The transformation is based on a rigid rotation of principal component axes (PCAs) derived from a global sample spanning one full year of NBAR 16-day composites. To provide a standard for MODIS tasselled cap axes, we recommend an orientation in MODIS spectral band space as similar as possible to the orientation of the Landsat Thematic Mapper (TM) tasselled cap axes. To achieve this we first transformed our global sample of MODIS NBAR reflectance values to TM tasselled cap values using the existing TM transformation, then used an existing algorithm (Procrustes) to compute the transformation that minimizes the mean square difference between the TM transformed NBAR values and NBAR PCA values. This transformation can then be used as a standard to rotate the MODIS NBAR PCA axes into a new MODIS Kauth Thomas (KT) orientation. Global land cover patterns in tasselled cap space are demonstrated graphically by linking the global sample with several other products, including the MODIS Land Cover product (MOD12) and the MODIS Vegetation Continuous Fields product (MOD44). Patterns seen at this global scale agree with previous explorations of TM tasselled cap space, but are shown here in greater detail with a globally representative sample. Temporal trends of eight smaller-scale BigFoot Project (www.fsl.orst.edu/larse/bigfoot) sites were also examined, confirming the spectral shifts in tasselled cap space related to phenology.

The importance of these maps to fire rehabilitation crews highlights the need for continued assessment of alternative remote sensing approaches. To meet this need, this study presents a first preliminary comparison of immediate post-fire char (black ash) fraction, as measured by linear spectral unmixing, and Delta NBR, with two quantitative one-year post-fire field measures indicative of canopy and sub-canopy conditions: % live tree and dry organic litter weight ( gm 22). Image analysis was applied to Landsat 7 Enhanced Thematic Mapper (ETM+) imagery acquired both before and immediately following the 2000 Jasper Fire, South Dakota. Post-fire field analysis was conducted one-year post-fire. Although the immediate post-fire char fraction (r(2)=50.56, SE=28.03) and Delta NBR (r(2)=0.55, SE=29.69) measures produced similarly good predictions of the % live tree, the standard error in the prediction of litter weight with the char fraction method (r(2=)0.55, SE=4.78) was considerably lower than with DNBR (r(2)=0.52, SE=8.01). Although further research is clearly warranted to evaluate more field measures, in more fires, and across more fire regimes, the char fraction may be a viable approach to predict longer-term indicators of ecosystem recovery and may potentially act as a surrogate retrospective measure of the fire intensity.

The index has three variants related to surface elevation, and is calculated from temperature and humidity measurements at atmospheric pressure levels. To effectively use the Haines Index, fire forecasters and managers must be aware of the climatological and statistical characteristics of the index for their location. However, a detailed, long-term, and spatially extensive analysis of the index does not currently exist. To meet this need, a 40- year (1961-2000) climatology of the Haines Index was developed for North America. The climatology is based on gridded (2.5 degrees latitude x 2.5 degrees longitude) temperature and humidity fields from the NCEP/NCAR reanalysis. The climatology illustrates the large spatial variability in the Haines Index both within and between regions using the different index variants. These spatial variations point to the limitations of the index and must be taken into account when using the Haines Index operationally. C1 Michigan State Univ, Dept Geog, E Lansing, MI 48824 USA.

The goal of these simulations is to explore the potential extent of the coupling between the fire, atmosphere, and topography. The ten simulations described in this paper include five different topographies, each run with two different ambient wind speeds of 6 and 12ms(-1). The five topologies explored are: an idealised hill (which serves as the base centerline for the other topographies), two variations of the hill with lateral gradients downwind from the ignition line (one sloping up from the 'hill' at the centerline to form an upward sloping canyon parallel to the ambient wind, and the other sloping down from the centerline to form a ridge parallel to the ambient flow), one with a second hill upwind of the ignition line such that the fire is ignited in the bottom of a canyon that runs perpendicular to the ambient wind, and finally a flat terrain. The four non-trivial topographies have the same profile along the centerline downwind of the ignition line to help assess the impacts of topographic gradients that are perpendicular to the ambient wind. It is hoped that analysis of these simulations will help reveal where point-functional models are sufficient, where topographically modified wind fields are needed, and where fully coupled fire and transport models are necessary to properly describe wildfire behaviour.

Developed by Ralph Nelson in the 1990s, the Nelson model is a dead-fuel moisture model designed to take advantage of frequent automated weather observations. Originally developed for 10-h fuels, the model is adaptable to other fuel size classes through modification of the model's fuel stick parameters. The algorithms for dead-fuel moisture in the National Fire Danger Rating System (NFDRS), on the other hand, were originally developed in the 1970s, utilise once-a-day weather information, and were designed to estimate dead-fuel moisture for mid-afternoon conditions. Including all field observations over the 21-month period, the Nelson model showed improvement over NFDRS for each size fuel size class, with r(2) values ranging from 0.51 (1000-h fuels) to 0.79 (10-h fuels). However, for observed fuel moisture at or below 30%, the NFDRS performed better than the Nelson model for 1-h fuels and was about the same accuracy as the Nelson for 10-h fuels. The Nelson model is targeted for inclusion in the next-generation NFDRS. C1 Oklahoma State Univ, Stillwater, OK 74078 USA. USDA, Forest Serv, Fire Sci Lab, Rocky Mt Res Stn, Missoula, MT 59807 USA.

Many of the relationships identified then persist today in the form of our National Fire-Danger-Rating System. This paper traces the evolution of fire-danger rating in the United States, including discussions of significant developmental milestones, innovative instrumentation, and a succession of analogue fire- danger meters, or calculators. Although the primary theme of this paper is an historical review of pioneering efforts leading up to our current state-of-knowledge, a common thread throughout this paper is the desire by every generation of developer to achieve a 'purely analytical system'. A national system was first introduced in 1964. The current system used throughout the USA was implemented in 1978, with optional revisions added in 1988. We present this evolution within the context of three periods of development: first, the pioneering efforts initiated at the Priest River Experiment Station in northern Idaho; second, the implementation of a national, standardised fire-danger-rating system; and third, spatially explicit delivery systems that provide a national view of weather and fire potential, which include national fire- danger and weather maps and satellite-derived maps that reflect the state of live vegetation across the United States.

TI Wildland-urban interface housing growth during the 1990s in California, Oregon, andWashington SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article ID NORTHERN SIERRA-NEVADA; LAKE TAHOE BASIN; UNITED-STATES; FIRE REGIMES; SURFACE FIRE; FOREST; MANAGEMENT; USA; MOUNTAINS; PATTERNS AB In the present study, we examine housing growth in California, Oregon, and Washington in the wildland-urban interface (WUI), the area where homes and other structures abut or intermingle with wildland vegetation. We combine housing density information from the 1990 and 2000 USA censuses with land cover information from the 1992/93 National Land Cover Dataset to demarcate the location and extent of the WUI and its growth, both in terms of area and number of housing units during the 1990s. We overlay the WUI with coarse-scale fire regime condition class information to evaluate implications for wildland fire management. During the 1990s, WUI area in the three-state region increased by 5218 km(2) (10.9%) to nearly 53 000 km(2) and the number of housing units in the WUI increased over 1 million units (17.6%) and in 2000 encompassed 6.9 million units, 43% of all housing in the region. Over a million new homes were constructed in the WUI, comprising 61% of the new homes constructed in the region. By 2000, there was far more intermix WUI (75% of the WUI area and 64% of the WUI housing units) than interface WUI. Expansion of the WUI accounted for only 13% of WUI housing unit growth and WUI that existed in 1990 encompassed 98% of WUI housing units in 2000. In 2000, there were nearly 1.5 million WUI housing units in areas with 0-35-year fire return intervals and 3.4 million in areas with 35-100+ year fire return intervals. In both these fire regimes, the majority of WUI housing units (66% and 90% respectively) are in areas with a current condition outside the historic range of variability. Housing growth patterns in this three-state region are exacerbating wildland fire problems in the WUI. Any long-term solution to wildland fire issues in the western United States will have to address housing growth patterns. Using a consistent, nationally applicable assessment protocol, the present study reveals the vast extent of WUI in the west coast states and its growth in the 1990s, and provides a foundation for consistent monitoring efforts.

Several 'dark' or 'yellow' days, as such events are commonly called, have been recorded, often with anecdotal or direct evidence pointing to wildfires as the source ( Plummer 1912; Ludlum 1972). One such 'dark day' occurred across New England in 1780, a year in which people were technologically unable to confirm the source of such a phenomenon. Here we combine written accounts and fire scar evidence to document wildfire as the likely source of the infamous Dark Day of 1780.

We applied classification tree analyses to a 16-year fire database from northern Wisconsin to evaluate the relative importance of human v. biophysical variables affecting fire occurrence within (1) all cover types, and (2) within forest types in each of four different fire size groupings ( all fires; fires >= 0.4 ha (1 acre); fires >= 4 ha (10 acres); fires >= 16 ha (40 acres)). Housing density was the most important indicator of fire observations. Increasing minimum fire size increased the relative importance of biophysical variables. Key biophysical variables included land cover type, soil moisture indicators, and an index of presettlement fire rotation associated with glacial landforms. Our results indicate the likelihood of fire starts is primarily influenced by human activity in northern Wisconsin, whereas biophysical factors determine whether those fire starts become large fires. Important interactions between human and biophysical variables were observed for nearly all fire types and size thresholds examined. Our results have implications for both ecological restoration and the management of fire risk within historically fire-prone systems currently experiencing rapid rural development.

TI Combustion characteristics of north-eastern USA vegetation tested in the cone calorimeter: invasive versus non-invasive plants SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article ID FLAMMABILITY AB In the north-eastern United States, invasive plants alter forest fuels, but their combustion characteristics are largely unknown. We assessed unground samples of foliage and twigs in the cone calorimeter for 21 non-invasive, native species, paired with 21 invasive species (18 non- native). Variables included sustained ignition, peak heat release rate, total heat release, and especially average effective heat of combustion, which is independent of initial sample mass. Heat of combustion was overall slightly lower for invasive species than for counterpart non-invasive species, and was significantly lower for Norway maple, black locust, and glossy buckthorn than for three non-invasive trees. It was low for invasive Japanese stiltgrass, sheep sorrel, and glossy buckthorn, and for non-invasive whitegrass, interrupted fern, grape, sphagnum moss, and three-lobed bazzania. Heat of combustion was high for invasive roundleaf greenbrier (native), scotchbroom, tree-of-heaven, Japanese honeysuckle, Japanese barberry, swallow-wort, and garlic mustard, and for non-invasive plants of fire-prone ecosystems: black huckleberry, pitch pine, bear oak, northern bayberry, and reindeer lichen. Heat content of twigs and foliage interrelates with other factors that affect fire behaviour, yet the cone calorimeter results enabled comparison of combustion properties among many species. These data have potential application as improved inputs for fire behaviour modelling. C1 US Forest Serv, USDA, No Res Stn, Bradley, ME 04411 USA.

The costs and benefits for individual helicopters are unique. Costs consist of daily availability and hourly flight rates. Benefits depend on the payload, which depends on the altitude and temperature of operation, weight of the helicopter, equipment on board, crew, and fuel. Because of the complexity of calculating payload, previous methods for deploying helicopters classified helicopters into three types according to their typical payload. The least expensive helicopter of the desired type was deployed. Because this classification system produces a broad range of benefits within each helicopter type, this method may not deploy the most efficient helicopter. The helicopter comparison index can be calculated at representative altitudes and temperatures before it is needed. As the work is done beforehand, the helicopters can be compared quickly when they are needed. The helicopter comparison index allows helicopters to be compared based on the efficiency of the individual helicopters rather than just their cost of operation. Evaluation of Type I helicopters shows that using the helicopter comparison index instead cost of operation has savings potential of 20 to 45 percent.

Matt TI Sensitivity of a surface fire spread model and associated fire behaviour fuel models to changes in live fuel moisture SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE fire behaviour models; live fuel moisture; live fuel moisture of extinction; safety zones AB Fire behaviour models are used to assess the potential characteristics of wildland fires such as rates of spread, fireline intensity and flame length. These calculations help support fire management strategies while keeping fireline personnel safe. Live fuel moisture is an important component of fire behaviour models but the sensitivity of existing models to live fuel moisture has not been thoroughly evaluated. The Rothermel surface fire spread model was used to estimate key surface fire behaviour values over a range of live fuel moistures for all 53 standard fuel models. Fire behaviour characteristics are shown to be highly sensitive to live fuel moisture but the response is fuel model dependent. In many cases, small changes in live fuel moisture elicit drastic changes in predicted fire behaviour. These large changes are a result of a combination of the model-calculated live fuel moisture of extinction, the effective wind speed limit and the dynamic load transfer function of some of the fuel models tested. Surface fire spread model sensitivity to live fuel moisture changes is discussed in the context of predicted fire fighter safety zone area because the area of a predicted safety zone may increase by an order of magnitude for a 10% decrease in live fuel moisture depending on the fuel model chosen.

The mortality model included in the commonly used USA fire behaviour and effects models, the First Order Fire Effects Model (FOFEM), BehavePlus, and the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS), has not been tested with independently collected post-fire tree mortality data. The model predicts mortality for a wide range of conifer species based on crown scorch and species-specific bark thickness. We evaluated the mortality model on 13 western USA conifers: subalpine fir, red fir, white fir, Douglas-fir, incense cedar, western larch, western hemlock, Engelmann spruce, whitebark pine, lodgepole pine, ponderosa pine, Jeffrey pine, and sugar pine. Predicted stand-level mortality was within +/- 20% of observed mortality for all species except incense cedar, western larch, red fir, and western hemlock. Individual tree mortality prediction was most accurate for subalpine fir, incense cedar, ponderosa pine, and Jeffrey pine. Evaluation of the model provides managers with an accuracy assessment for estimating the probability of mortality for the majority of western USA conifers when using the mortality model to make land management decisions.(A).

TI A computational method for optimising fuel treatment locations SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE fire modelling; prescribed burning ID FIRE HAZARD REDUCTION; MANAGEMENT; FOREST; PRINCIPLES; ECOSYSTEMS; WILDFIRES; SEVERITY; PATTERNS; BEHAVIOR; GROWTH AB Modelling and experiments have suggested that spatial fuel treatment patterns can influence the movement of large fires. On simple theoretical landscapes consisting of two fuel types (treated and untreated), optimal patterns can be analytically derived that disrupt fire growth efficiently (i.e. with less area treated than random patterns). Although conceptually simple, the application of these theories to actual landscapes is made difficult by heterogeneity (fuels, weather, and topography). Here a computational method is described for heterogeneous landscapes that identifies efficient fuel treatment units and patterns for a selected fire weather scenario. The method requires input of two sets of spatial input data: (1) the current fuel conditions; and (2) the potential fuel conditions after a treatment is conducted (if treatment is permitted in a particular location). The contrast in fire spread rate between the two landscapes under the weather scenario conditions indicates where treatments are effective at delaying the growth of fires. Fire growth from the upwind edge of the landscape is then computed using a minimum travel time algorithm. This identifies major fire travel routes (areas needing treatment) and their intersections with the areas where treatments occurred and reduced the spread rate (opportunity for treatment). These zones of treatment 'need and opportunity' are iteratively delineated by contiguous patches of raster cells up to a user-supplied constraint on percentage of land area to be treated. This algorithm is demonstrated for simple and for complex landscapes. C1 USDA, Forest Serv, Missoula Fire Sci Lab, Missoula, MT 59808 USA.

TI Simulation of long-term landscape-level fuel treatment effects on large wildfires SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE fire modelling ID POTENTIAL FIRE BEHAVIOR; MIXED-CONIFER FORESTS; HAZARD REDUCTION; PRINCIPLES; MANAGEMENT; SEVERITY; GROWTH; STAND; RISK; USA AB A simulation system was developed to explore how fuel treatments placed in topologically random and optimal spatial patterns affect the growth and behaviour of large fires when implemented at different rates over the course of five decades. The system consisted of a forest and fuel dynamics simulation module ( Forest Vegetation Simulator, FVS), logic for deriving fuel model dynamics from FVS output, a spatial fuel treatment optimisation program, and a spatial fire growth and behaviour model to evaluate the performance of the treatments in modifying large fire growth. Simulations were performed for three study areas: Sanders County in western Montana, the Stanislaus National Forest in California, and the Blue Mountains in south-eastern Washington. For different spatial treatment strategies, the results illustrated that the rate of fuel treatment ( percentage of land area treated per decade) competes against the rates of fuel recovery to determine how fuel treatments contribute to multidecade cumulative impacts on the response variables. Using fuel treatment prescriptions that simulate thinning and prescribed burning, fuel treatment arrangements that are optimal in disrupting the growth of large fires require at least 1 to 2% of the landscape to be treated each year. Randomly arranged units with the same treatment prescriptions require about twice that rate to produce the same fire growth reduction. The results also show that the topological fuel treatment optimisation tends to balance maintenance of previous units with treatment of new units. For example, with 2% landscape treatment annually, fewer than 5% of the units received three or more treatments in five decades with most being treated only once or twice and similar to 35% remaining untreated after five decades.

TI Water use estimates for various rice production systems in Mississippi and Arkansas SO IRRIGATION SCIENCE LA English DT Article AB Rice irrigation-water use was estimated in Mississippi (MS) and Arkansas (AR) in 2003 and 2004. Irrigation inputs were compared on naturally sloping (i.e. contour-levee system) and mechanically graded fields. In MS, rice production consumed, on average, 895 mm water, but irrigation inputs were greatly affected by production system. Contour-levee systems accounted for 35% of the production area and consumed 1,034 mm irrigation. Fields mechanically graded to a consistent slope of approximately 0.1% (i.e. straight-levee systems) consumed 856 mm irrigation and accounted for 60% of the production area. Fields devoid of slope (i.e. zero-grade system) accounted for 5% of the production area and consumed 382 mm irrigation. In AR, contour-levee rice production consumed 789 mm compared to 653 mm with a straight-levee system. Using low pressure, thin wall (9-10 mil) disposable irrigation tubing to deliver water to each paddy independently reduced irrigation inputs by 28% in MS and 11% in AR when compared to a single-point (levee-gate) distribution system.

The chemistry of seed total P largely revolves around the synthesis and storage of phytic acid (myo-inositol hexaphosphate). Forward genetics research. beginning with the isolation of low, phytic acid (lpa) Mutants, has led to the identification of genes important to phytic acid synthesis and transport in seeds. Lpa mutations have been isolated in maize (Zea mays L). barley (Hordeum vulgare L.). rice (Oryza sativa L), wheat (Triticum aestivum L.). and soybean (Glycine max L. (Merr.)), and chromosomal mapping has identified as many as six non-allelic loci in a single species (barley). These recessive alleles have been used to breed low-phytate cultivars, inbreds, and hybrids, and these have Subsequently been used in biological, agronomic, and nutritional studies. One interesting finding is that homozygosity for recessive alleles of barley lpal, not only reduced seed phytic acid by about 50%. but also seed total P by about 15%. The "low seed total P" trait would be useful when grains or grain products are used for biofuel production or in feeds used in dairy or beef production. Future work will continue to study the genetics and biology of seed phytic acid, but even greater opportunity exists for progress in the genetics of seed total P. The beauty of forward genetics in this area of research and in other areas of plant biology is its potential its a tool of discovery.

It has been proposed that independent mutations at orthologous loci in traits such as shattering, tough fruiting cases (glumes, in the case of wheat), and threshing may have led to domestication-driven convergent evolution. A different picture is emerging from comparative mapping and cloning of these genes in different cereal crops. It appears that these spike traits are controlled by multiple genetic pathways, and mutations at different loci have been selected during domestication-driven evolution.

Both compounds produced comparable amounts of oxidative stress; however, normalization by alpha-tocopherol occurred solely after inhibition by ritonavir, and not by ALLN. Similar to that, alpha-tocopherol could normalize the reduced formation of 3-nitro-tyrosinemodified proteins only after ritonavir treatment. In the absence of any proteasome inhibitor, intrinsic cellular proteasome activity was not modulated by alpha-, beta-, and gamma-tocopherols; however, delta-tocopherol, alpha-tocotrienol, and alpha-tocopheryl phosphate could significantly inhibit cellular proteasome activity and increased the level of p27(Kip1) and p53. Since oxidative stress was reduced by alpha-tocopherol only after proteasome inhibition by ritonavir and not by ALLN, it is concluded that, in this experimental system, alpha-tocopherol does not act as an antioxidant but interferes with the inhibitory effect of ritonavir.

Population dynamics of TL at two localities in Valle del Cauca, Colombia, indicated a density of 1.2 TL per sweep (12 TL per 10 sweeps). Densities equal to the calculated action thresholds were not observed in rice fields in Valle del Cauca, Colombia, during the study period. Infestation to 15- or 20-day-old plants did not cause yield reductions, thus suggesting that scouting for this pest should be concentrated on 25- to 40-day-old plants.

SO JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS LA English DT Article DE devolatilization; pyrolysis; scarification; barley hull-enriched fractions; TGA; PY-GC-MS; thermochemical; ethanol making; biorefinery; biofuel ID RICE HULL; KINETICS AB Characterization of biomass devolatilization products can provide important information for understanding the synergy between its decomposition pathways and subsequent thermochemical energy conversion processes such as direct combustion, gasification or production of intermediate pyrolysis products including bio-oils. The proposed use of hulled barley (Hordeunt vulgare L.), as feedstock for ethanol production in the corn deficit Eastern and Northwestern United States would generate significant quantities of residual hulls but can also be a potential source of thermal energy capable of improving the economies of the process. In this study, the initial thermal degradation of hull-enriched fractions from three barley varieties including slow and fast pyrolysis was characterized via thermolysis. The study employed a wide range of pyrolysis experiments including thermogravimetry (TGA), pyrolysis-gas chromatography with mass-spectral analysis (PY-GC-MS) and hot phase environmental scanning electro microscopy (ESEM). All experiments were performed within the high temperature range of 600-1050 degrees C. The apparent first order rates of the early stages of the clevolatilization process in the TGA showed no significant differences in the estimated activation energy of the varieties tested. The pyrolysis yields grouped under condensable gas (bio-oil), non-condensable gas (synthetic gas), and char were more temperature dependent than variety dependent. Similar results were found with the fractional composition of the synthesis gas. The hot stage environmental SEM revealed interesting gas evolution patterns and char microstructure development in real time during thermal degradation of the biomass. The information presented is useful for the understanding of the thermochemical conversion of barley hull-containing fractions and offers design implications regarding unit operations either for stand-alone biomass energy conversion systems or for co-located systems in an integrated ethanol production facility.

Forty mate twins, Canary Caprine kids were randomly allocated to one of four treatments. Two groups were reared With their Dams (WD) while the other two were reared using a Milk Replacer (MR). Two end point live weights (LWS; 6 and 10 kg) were used for each feeding system. WD Kids grew faster (32%) than MR. The empty body weight, hot carcass weight and Cold Carcass Weight (CCW) were higher in the 10-kg compared to the 6-kg kids. In relation to carcass conformation measures and indices, there were differences (p<0.01) between the two diets for carcass length and leg length measurements. No effects of diet or LWS were observed for the percentage of primal cuts. WD kids were fatter than MR kids. The kids slaughtered at 10 kg LWS were fatter and less bony than 6 kg kids. The results showed that suckling method had few effects on carcass quality, but increasing slaughter weight substantially improved carcass quality. C1 [Solomon, M.

SO JOURNAL OF ANIMAL ECOLOGY LA English DT Article DE density dependence; intraspecific competition; site-dependent; territorial competition ID ATLANTIC SALMON; POPULATION-DENSITY; HABITAT QUALITY; SPACE-USE; TROUT; MODEL; FISH; SALAR; DRIFT; STRATEGIES AB Empirical studies show that average growth of stream-dwelling salmon and trout often declines with increasing density in a characteristic concave relationship. However, the mechanisms that generate negative density-growth relationships in populations in natural streams are not certain. In a recent study, Imre, Grant & Cunjak (2005; Journal of Animal Ecology, 74, 508-516) argue that density-dependent growth due to exploitative competition for prey causes the negative density-growth relationships for stream salmonids. They argue that the concave shape of empirical density-growth relationships is consistent with a simple model of exploitative competition and not consistent with interference competition for space. We use a simple model to show that competition for space can yield concave density-growth relationships consistent with the empirical pattern when individuals compete for foraging sites that vary spatially in quality and lower-quality sites predominate. Thus, the predictions of the exploitative competition and spatial competition models overlap. The shape of the density-growth relationship does not differentiate between candidate mechanisms underlying density-dependent growth for stream salmonids. Our results highlight the general problem with determining the mechanism driving an ecological process from patterns in observational data within the context of linking population demographics to habitat structure and animal behaviour.

TI Evaluation in beef cattle of six deoxyribonucleic acid markers developed for dairy traits reveals an osteopontin polymorphism associated with postweaning growth SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE cattle; growth; marker; osteopontin; quantitative trait loci; SPP1 ID MILK-PRODUCTION TRAITS; HORMONE RECEPTOR; CARCASS TRAITS; HAPLOTYPE RECONSTRUCTION; BOVINE CHROMOSOME-2; MISSENSE MUTATION; COMMERCIAL LINE; CANDIDATE GENE; MAMMARY-GLAND; MICE LACKING AB The objectives of this study were to 1) estimate the allelic frequencies in US beef cattle of 6 DNA markers reported to be associated with variation in dairy production traits; and 2) evaluate the association of these markers with beef production traits. Several genetic markers have been associated with milk yield or composition, including polymorphisms in secreted phosphoprotein 1 (SPP1; also called osteopontin), growth hormone receptor (GHR), casein S1 (CSN1S1), diacylglycerol O-acyltransferase 1 (DGAT1), peroxysome proliferator-activated receptor gamma coactivator-1alpha (PPARGC1A), and ATP-binding cassette subfamily G ( white) member 2 (ABCG2). Allelic frequencies for these 6 markers, and their association with 21 phenotypes, were evaluated in 2 crossbred beef cattle populations that sample influential industry sires. Five of 6 markers were segregating in beef cattle populations; the exception was ABCG2. The SPP1 marker was associated with yearling weight (P = 0.025), live weight at slaughter (P = 0.016), postweaning ADG (P = 0.007), and HCW (P = 0.007) in a large, multisire population representing the 7 most populous beef breeds in the United States. Postweaning growth trait associations were confirmed in an independent population of similar construction, including sires from tropically adapted breeds. The SPP1 marker was associated with yearling weight (P = 0.034), live weight at slaughter (P = 0.011), and postweaning ADG (P = 0.015) and showed a trend toward association with HCW ( P = 0.083) in this population. Whereas DGAT1, GHR, and CSN1S1 polymorphisms showed association with some traits in individual populations, the lack of consistent predictive merit between populations indicates they may not be suited for beef cattle selection. No significant associations were observed for the PPARGC1A marker and any of 21 recorded traits, indicating this marker had no apparent value in selection for the beef cattle traits tested in these populations. The SPP1 marker had consistent associations and effect sizes (10.5 to 11.5 kg of live weight at slaughter) in both populations, providing strong evidence for utility of the SPP1 marker for postweaning growth in beef cattle.

TI Genetic parameters for body weight, hip height, and the ratio of weight to hip height from random regression analyses of Brahman feedlot cattle SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE Brahman; feedlot; height; random regression; body weight ID PHENOTYPIC COVARIANCE FUNCTIONS; X ENVIRONMENT INTERACTIONS; COMPOSITE BEEF-CATTLE; TALL FESCUE PASTURES; SCROTAL CIRCUMFERENCE; COMMON BERMUDAGRASS; POSTWEANING GROWTH; PRODUCTION TRAITS; YEARLING WEIGHT; CONDITION SCORE AB The objective of this research was to assess the genetic control of BW, hip height, and the ratio of BW to hip height (n = 5,055) in Brahman cattle through 170 d on feed using covariance function-random regression models. A progeny test of Brahman sires ( n = 27) generated records of Brahman steers and heifers ( n = 724) over 7 yr. Each year after weaning, calves were assigned to feedlot pens, where they were fed a high-concentrate grain diet. Body weights and hip heights were recorded every 28 d until cattle reached a targeted fatness level. All calves had records through 170 d on feed; subsequent records were excluded. Models included contemporary group (sex-pen-year combinations, n = 63) and age at the beginning of the feeding period as a covariate. The residual error structure was modeled as a random effect, with 2 levels corresponding to two 85-d periods on feed. Information criterion values indicated that linear, random regression coefficients on Legendre polynomials of days on feed were most appropriate to model additive genetic effects for all 3 traits. Cubic ( hip height and BW: hip height ratio) or quartic ( BW) polynomials best modeled permanent environmental effects. Estimates of heritability across the 170-d feeding period ranged from 0.31 to 0.53 for BW, from 0.37 to 0.53 for hip height, and from 0.23 to 0.6 for BW: hip height ratio. Estimates of the permanent environmental proportion of phenotypic variance ranged from 0.44 to 0.58 for BW, 0.07 to 0.26 for hip height, and 0.30 to 0.48 for BW: hip height ratio. Within-trait estimates of genetic correlation on pairs of days on feed (at 28-d intervals) indicated lower associations of BW: hip height ratio EBV early and late in the feeding period but large positive associations for BW or hip height EBV throughout. Estimates of genetic correlations among the 3 traits indicated almost no association of BW: hip height ratio and hip height EBV. The ratio of BW to hip height in cattle has previously been used as an objective measure of BCS in cows or calves; it may offer a unique assessment of body dimension. Results indicated that there is substantial additive genetic variation for this trait, and it may be possible to use EBV to increase BW without increasing frame score in Brahman cattle.

TI The impact of dietary protein source on observed and predicted metabolizable energy of dry extruded dog foods SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE amino acid; crude protein; dog; fiber; metabolizable energy ID MEAN RETENTION TIME; LOW-OLIGOSACCHARIDE; NUTRIENT INTAKE; CANINE FOODS; DIGESTIBILITY; PRODUCTS; FIBER AB Fifty-five observations were used to determine the ME content of 8 foods containing different protein sources. The major protein sources tested included low-oligosaccharide whole soybeans; 2 low-oligosaccharide, low-phytate whole soybeans; 2 conventional soybean meals; low-ash poultry meal; low-oligosaccharide, low-phytate soybean meal; and conventional whole soybeans. The ME content of all foods ranged from 3,463 to 4,233 kcal/kg of DM. The first objective was to utilize the observed ME data and test the accuracy of the modified Atwater equation. In this study, the modified Atwater equation generally underpredicted ME compared with the observed ME ( residual mean = 247 kcal/kg). The second objective was to use individual data to develop an equation, based on the chemical composition of the food, to predict the ME content of the foods. A multivariate regression analysis was used to predict ME content based on chemical composition. Five models were fitted to the data. Model 1 included CP, ether extract (EE), and crude fiber (CF). Because the foods varied in protein sources, and the ratio of total AA (TAA) to non-AA (NAA) CP ranged from 3.5:1 to 14.4:1, it was hypothesized that accounting for the proportion of TAA and NAA in CP would improve the fit of the model. Therefore, model 2 included TAA, NAA, EE, and CF. Defining CP in terms of TAA and NAA improved the r(2) of the model from 0.46 to 0.79. Subsequently, models 3, 4, and 5 replaced the CF term with ADF, NDF, and hemicellulose ( HEM). Model 3 included TAA, NAA, EE, and NDF. Model 4 included TAA, NAA, EE, ADF, and HEM. Model 5 included TAA, NAA, EE, and HEM. Defining dietary fiber in terms of HEM improved the r(2) of model 2 from 0.79 to 0.81. Residual analysis suggested that replacing the CF term with HEM( model 5) improved the prediction of ME content. In contrast, defining fiber in terms of NDF ( model 3) did not result in an improvement over model 2, whereas the ADF term ( model 4) did not ( P > 0.34) contribute to the overall model. Fractionating CP into TAA and NAA components further defined the chemical composition of the food. These data suggest that defining protein composition improves the accuracy of predicting the ME content of dog foods. C1 Univ Kentucky, Dept Anim Sci & Food Sci, Lexington, KY 40546 USA.

TI Afternoon harvest increases readily fermentable carbohydrate concentration and voluntary intake of gamagrass and switchgrass baleage by beef steers SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE beef steer; diurnal harvest; gamagrass; silage; switchgrass ID DRY-MATTER INTAKE; TALL FESCUE; HAYS CUT; CHEWING BEHAVIOR; NUTRITIVE-VALUE; DAIRY-COWS; FORAGE; PREFERENCE; NITROGEN; SUNDOWN AB Our objective was to determine if harvest in the morning (AM, 0600) vs. the afternoon (PM, 1800) affects composition and voluntary DMI of gama-grass (GG) or switchgrass (SG) stored as baleage. Iuka GG(Tripsacum dactyloides L.) and Alamo SG (Panicum virgatum L.) were cut with a mower-conditioner, immediately round-baled, wrapped in plastic, and stored as baleage. Beef steers (255 +/- 7 kg of BW) were assigned (5 steers/treatment) to GG/AM, GG/PM, SG/AM, or SG/PM. Ad libitum intake was measured for 21 d (7-d adjustment and 14-d intake estimate) followed by 7-d adjustment and 5-d digestion and N balance study. Chewing behavior was recorded during the balance study. Compared with AM, PM had more (P < 0.01) starch (9.3 vs. 4.7 g/kg of DM), total nonstructural carbohydrate (30.4 vs. 19.0 g/kg of DM), and monosaccharides (17.1 vs. 11.2 g/kg of DM). Compared with AM, PM had less (P = 0.05) acetate (13.0 vs. 18.6 g/kg of DM) and propionate (0.29 vs. 0.82 g/kg of DM) and tended (P < 0.13) to have less lactate (2.9 vs. 3.5 g/kg of DM) and butyrate (3.9 vs. 5.1 g/kg of DM). Compared with SG, GG had more (P = 0.01) DM (324 vs. 242 g/kg of baleage), CP (114 vs. 97 g/kg of DM), lactate (4.8 vs. 1.6 g/kg of DM), starch (9.4 vs. 4.7 g/kg of DM), total nonstructural carbohydrate (34.2 vs. 15.2 g/kg of DM), and monosaccharides (20.8 vs. 7.4 g/kg of DM). However, GG had a lower (P = 0.01) pH (5.32 vs. 5.79) and less (P < 0.01) ethanol (18.7 vs. 27.3 g/kg of DM), acetate (12.3 vs. 19.2 g/kg of DM), propionate (0.00 vs. 1.11 g/kg of DM), and butyrate (0.6 vs. 8.4 g/kg of DM). Daily DMI (2.16 vs. 1.83% of BW) and digestible DMI (1.15 vs. 0.95% of BW) were greater (P = 0.03) for PM than AM. Plasma urea N concentrations at the end of the ad libitum intake phase were greater (P = 0.01) for AM (3.91 mM) than for PM (2.31 mM) and greater (P = 0.07) for GG (3.51 mM) than for SG (2.71 mM). Steers fed PM spent more time eating (P = 0.04) and less time resting (P = 0.01) during meals than steers fed AM. Apparent digestibility of DM and fiber components was not affected (P < 0.18) by treatment. Apparent digestibility and retention of N decreased from PM to AM for SG, but increased for GG (P = 0.05). Retention of Nas a percentage of N intake or N digested decreased more from PM to AM for SG than for GG (P < 0.05). We conclude that increased nonstructural carbohydrate content of the PM harvest of these grasses stored as baleage caused increased voluntary intake and improved use of dietary N by beef steers.
