Inoculated whole kernels were compared to noninoculated kernels. Concentrations of sucrose and raffinose in inoculated seed decreased to nearly zero at 6 days, whereas concentrations of these saccharides in noninoculated seed dropped at a considerably slower rate, and significant levels remained at the end of the incubation period. Triglyceride concentrations remained unchanged in the noninoculated seed but dropped continuously after 2 days in the inoculated seed. Starch and zein concentrations did not change during the 12-day incubation period. Aflatoxin B, was first detected after 2 days and increased to about 20 mu g/g (20,000 ppb) after 12 days. Very low aflatoxin concentrations were detected in the noninoculated seed. Significant concentrations of erythritol, arabitol, and mannitol were produced during infection, with peak concentrations occurring at 8 days. Whole seed and germ tissue appeared to support good fungal growth and aflatoxin production, whereas ground tissues and endosperm did not. A. flavus preferentially utilized saccharides as initial carbon substrates followed by triglycerides. When invading nonwounded corn kernels, the fungus selectively targets the germ tissue where these materials are localized in the highest concentrations.

SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE Ricinus communis; oilseed; ricin gene; agglutinin gene ID LECTIN GENE; SEQUENCE; CHAIN; CLONING AB Castor oil is the only commercial source of ricinoleic acid and has numerous industrial applications. Among the factors limiting domestic production of castor oil is the presence of the toxin ricin and its less toxic homologue Ricinus communis agglutinin (RCA) in seeds. Although the sequences of ricin and RCA genes are known, their transcriptional expression patterns have not been distinguished due to their high degree of sequence similarity. As the information is critical for assessing success in developing a ricin-free castor crop using genetic silencing, we have designed a gene specific reverse transcription-polymerase chain reaction (RT-PCR) assay to examine the expression of the ricin and RCA genes in developing seeds. The results show that the ricin and RCA mRNA are highly abundant in seeds during the development of endosperm, and the expression pattern is similar to that observed in the Northern analysis. The RT-PCR results can be confirmed by a simple RT-PCR-based restriction fragment analysis. C1 USDA ARS, Western Reg Res Ctr, Albany, CA 94710 USA.

The supplement was mixed into the total maintenance ration and fed to the cows for 40 days after which unfortified diets were fed for 40 additional days. Dioxins and coplanar polychlorinated biphenyls (PCBs) were measured twice a week in the milk and in selected tissues of the cows, one at death (day 10 of withdrawal) and one at slaughter (day 40 of withdrawal). The dioxins and PCBs were readily transferred into the milk, and at steady state, total toxic equivalents were concentrated 6-fold into the milk fat from the diet. Bioaccumulation was inversely related to chlorination number. The elimination of dioxins and PCBs in milk was biphasic. With the exception of 1,2,3,4,6,7,8-heptachlorodioxin and both octachlorinated congeners, dioxin and furan half-lives in milk were approximately 3-5 days for the a-phase and 35-50 days for the beta-phase. PCB-169 had a longer half-life: 11 (alpha) and 200 days (beta). When milk and feed samples from Minnesota farms that had used similar contaminated mineral supplements were analyzed, no elevated dioxin levels were found in milk. It appeared that although the dioxins from the mineral supplements have the potential to bioaccumulate, dilution into the total diet was sufficient to prevent a significant rise in the dioxin concentrations in the milk at these farms.

We found that free-living worms, including the model genetic organism Caenorhabditis elegans, and parasitic helminths are unable to synthesize heme de novo, even though these animals contain hemoproteins that function in key biological processes. Radioisotope, fluorescence labeling, and heme analog studies suggest that C elegans acquires heme from exogenous sources. Iron-deprived worms were unable to grow in the presence of adequate heme unless rescued by increasing heme levels in the growth medium. These data indicate that although worms use dietary heme for incorporation into hemoproteins, ingested heme is also used as an iron source when iron is limiting. Our results provide a biochemical basis for the dependence of worm growth and development on heme, and they suggest that pharmacologic targeting of heme transport pathways in worms could be an important control measure for helminthic infections.

We simulated how altering within- and among-stand structure with silvicultural treatments of differing intensity affected late-seral forest (LSF) structure and fire threat (FT) reduction over 30 years in a 6070-ha reserve. We then evaluated how different financial requirements influenced the treatment mix selected for each decade, the associated effects on FT reduction and LSF structure in the reserve, and treatment costs. Requirements for treatments to earn money (NPV+), break even (NPV0), or to not meet any financial goal at the scale of the entire reserve (landscape) affected the predicted reduction of FT and the total area of LSF structure in different ways. With or without a requirement to break even, treatments accomplished about the same landscape level of FT reduction and LSF structure. Although treatment effects were similar, their associated net revenues ranged from negative $1 million to positive $3000 over 30 years. In contrast, a requirement for landscape treatments to earn money ($0.5 to $1.5 million NPV) over the same period had a negative effect on FT reduction and carried a cost in terms of both FT reduction and LSF structure. Results suggest that the spatial scale at which silvicultural treatments were evaluated was influential because the lowest cost to the reserve objectives was accomplished by a mix of treatments that earned or lost money at the stand level but that collectively broke even at the landscape scale. Results also indicate that the timeframe over which treatments were evaluated was important because if breaking even was required within each decade instead of cumulatively over all three, the cost in terms of FT reduction and LSF structure was similar to requiring landscape treatments to earn $0.5 million NPV (c) 2004 Elsevier B.V.

The running derivative of the ratio of the signal standard deviation (STD) to the accumulated sum of the STD is calculated, and the location of the global maximum of this function is found. No empirical criteria are required to determine smoke boundaries; thus the algorithm can be used without a priori selection of threshold values. The modified gradient method is not sensitive to the signal random noise at the far end of the lidar measurement range. Experimental data obtained with the Fire Sciences Laboratory lidar during routine prescribed fires in Montana were used to test the algorithm. Analysis results are presented that demonstrate the robustness of this algorithm. (c) 2005 Optical Society of America. C1 USDA, Forest Serv, Fire Sci Lab, Missoula, MT 59807 USA.

Most children exposed to elevated soil Pb, however, reside in urban areas, and no government programs exist to remediate such soils unless an industrial source caused the contamination. Modern regulated biosolids composts have low Pb concentrations and low bioaccessible Pb fractions and can improve grass growth on urban soils. High Fe and P biosolids composts can reduce the bioavailability and bioaccessibility of soil Pb and can aid in establishing vegetation that would reduce soil transfer into homes. For these reasons, we conducted a field test of their use to reduce Pb bioaccessibility in urban soils in Baltimore, MD USA. We chose biosolids compost for its expected reduction in the bioaccessible Pb fraction of urban soils, ease of use by urban residents, and ability to beautify urban areas. Nine urban yards with mean soil Pb concentrations > 800 mg Pb kg(-1) were selected and sampled at: several distances from the house foundation before soil treatment. The soils were rototilled to 20 cm depth to prepare the sites, and resampled. The yards were then amended with 6-8 cm depth of Orgro (R) biosolids compost (110-180 dry t/ha) rich in Fe and P, mixed well by rototilling, and resampled. Kentucky bluegrass (Poa pratensis) was seeded and became well established. Soils were resampled 1 year later. At each sampling time, total soil Pb was measured using a modified U.S. EPA nitric acid hotplate digestion method (SW 846 Method 3050) and bioaccessible Pb fraction was measured using the Solubility/Bioaccesibility Research Consortium standard operating procedure with modifications, including the use of glycine-buffered HCl at pH 2.2.. Samples of untreated soils were collected from each yard and mixed well to serve as controls for the Pb bioaccessibility of field treated soils over time independent of positional variance within yards. At 1-year post-treatment, grass cover was healthy and reductions in bioaccessible Pb concentrations compared to pre-tillage were 64% (from 1655 to 595 mg kg(-1)) and 67% (from 1381 to 453 mg kg(-1)) at the sampling lines closest to the houses. Little or no reduction in bioaccessible Pb concentration was observed at sampling lines more remote from the house that also had the lowest bioaccessible Pb concentrations at pre-tillage (620 and 436 mg kg(-1), respectively). For the control soils, changes over time in total Pb and bioaccessible Pb concentrations and the bioaccessible Pb fraction were insignificant. This study confirms the viability of in situ remediation of soils in urban areas where children are at risk of high Pb exposure from lead in paint, dust and soil. (c) 2004 Elsevier B.V.

These isolates were characterized as APMV-1 by the hemagglutination-inhibition (HI) assay utilizing NDV-specific polyclonal antisera. However, the isolates failed to react with a monoclonal antibody that has specificity for a wide variety of APMV-1 isolates. Although only highly virulent isolates require reporting to international regulatory agencies, the ability to correctly identify APMV-1 types is important for control and regulatory purposes. Protein gel patterns of the purified isolates resembled previously reported APMV-1 and anti-NDV polyclonal sera recognized the viral proteins. For three isolates oligonucleotide primers specific for the nucleoprotein, fusion protein and polymerase genes of NDV were utilized to synthesize cDNA using viral RNA as a template. Approximately 12 kb of the genome was subsequently sequenced for the three isolates that included the nucleoprotein, phosphoprotein, matrix protein, fusion (F) protein, hemagglutinin-neuraminidase protein genes and a 5' portion of the polymerase gene. The isolates had an F protein cleavage site sequence of ERQER/LVG indicating low-virulence viruses that phylogenetically separated with other unique NDV isolates designated as a lineage 6 genotype. Additionally, a four amino acid insert was detected in the predicted phosphoprotein which complies with the "rule of six" among paramyxoviruses. These APMV-1 genotypes have not been previously reported in North America and further substantiate the heterogeneous genetic nature of these commercially important pathogens found worldwide.

The sequence of Grx1as cDNA indicated that the open reading frame of the gene was identical to the open reading frame of the previously reported first human glutaredoxin ( Grx1) cDNA, but the 3'- untranslated region of Grx1as was not homologous to Grx1 cDNA. Northern blot and RT-PCR analyses showed Grx1as mRNA was expressed in normal human neutrophils and transformed cells including U937, HL-60, THP, and Jurkat cells. Cloning and sequencing of the genomic gene corresponding to Grx1as cDNA showed that two different glutaredoxin cDNAs ( Grx1as and Grx1) were generated from the same genomic gene via alternative splicing. Origination of Grx1as and Grx1 from the same gene was confirmed by chromosomal localization of the Grx1as gene to chromosome 5q13, the same location where the Grx1 gene was localized previously. During screening of the Grx1(as) genomic gene, two additional glutaredoxin pseudogenes were also isolated. Surprisingly, these pseudogenes contained 3'-untranslated regions that were nearly identical to the 3'-untranslated regions of Grx1(as), not Grx1, cDNA. Because 3'-untranslated regions may be important in stabilizing mRNAs, the effect of the two 3'-untranslated regions of Grx1 and Grx1(as) on mRNA stability was investigated using luciferase reporter vectors with the 3'-untranslated regions. Luciferase activity was 2.6-fold greater in cells transfected with the reporter vector containing the 3'-untranslated region of Grx1as cDNA compared with the 3'-untranslated region of Grx1 cDNA. These data indicate that Grx1as cDNA is an alternatively spliced human Grx1 cDNA and that the Grx1(as) 3'-untranslated region may have a role in stabilizing mRNA.

The effect of helical flow in bends is considered by adopting an algebraic model for the dispersion terms in the depth- averaged two-dimensional momentum and suspended-sediment transport equations and by adjusting the bed load transport angle. The governing equations are discretized using the finite volume method on a nonstaggered, curvilinear grid. Model validity has been assessed using experimental data observed in both fixed- and movable- bed laboratory flumes and a natural channel with submerged and emergent rigid vegetation. In general, mean flow velocities, sediment transport rates, and changes in bed topography predicted by the model agree well with the experimental observations. For laboratory and field cases, root-mean-square relative errors for velocities were less than about 13% and 44%, respectively, and about 50% of errors for changes in bed topography were less than 14.5% and 8% of the flow depth, respectively.

The nanoclays included the hydrophilic Cloisite Na+ clay as well as the more hydrophobic Cloisite 30B, 10A, and 15A clays. Frequency sweep and creep results for wheat starch-nanoclay samples at room temperature indicated that the Cloisite Na+ samples formed more gel-like materials than the other nanoclay samples. X-ray diffraction results showed no intercalation of Cloisite Na+ clays at room temperature, suggesting that starch granules interacted only with the clay surface and not the interlayer. When the various wheat starch-nanoclay samples were heated to 95 degrees C, the Cloisite Na+ samples exhibited a large increase in modulus. In contrast, the more hydrophobic nanoclay samples had comparable modulus values to the neat starch sample. These results suggested that during gelatinization, the leached amylose interacted with the Cloisite Na+ interlayer, producing better reinforcement and higher modulus values. X-ray diffraction results supported this interpretation since the data showed greater intercalation of Cloisite Na+ clay in the gelatinized samples. The samples containing wheat and corn starch showed comparable elastic modulus values during gelatinization. However, the potato and waxy corn samples had modulus values that rapidly decreased at higher temperatures. (c) 2004 Elsevier Ltd. All rights reserved.

Czern.] lines were tested under field conditions for their ability to remove selenium (Se) from Se- and boron-contaminated saline sediment. The transgenic lines overexpressed genes encoding the enzymes adenosine triphosphate sulfurylase (APS), gamma-glutamyl-cysteine synthetase (ECS), and glutathione synthetase (GS), respectively. The APS, ECS, and GS transgenic plants accumulated 4.3, 2.8, and 2.3-fold more Se in their leaves than wild type, respectively (P < 0.05). GS plants significantly tolerated the contaminated soil better than wild type, attaining an aboveground biomass/area almost 80% of that of GS plants grown on clean soil, compared to 50% for wild type plants. This is the first report showing that plants genetically engineered for phytoremediation can perform successfully under field conditions.

These conserved amino acids are not directly associated with catalytic function; rather they appear to be essential in the formation of disulfide bridges. Their role is seen as being similar to another eight-cysteine motif recently reported in the amino acid sequence of nearly 500 plant polypeptides. An additional disulfide bridge formed by two cysteines at the N-terminus of all the filamentous ascomycete phytases was also observed. Disulfide bridges are known to increase both stability and heat tolerance in proteins. It is therefore plausible that this extra disulfide bridge contributes to the higher stability found in phytase from some Aspergillus species. To engineer an enhanced phytase for the feed industry, it is imperative that the role of disulfide bridges be taken into cognizance and possibly be increased in number to further elevate stability in this enzyme.

The retrieval consists of a Bayesian scheme involving a tropospheric ultraviolet radiative transfer model. The technique was tested using cloud-free observations collected during a Mexico City Metropolitan Area air pollution field campaign from April to May 2003. Retrieval results compared favorably to those of independent techniques, including ozone amounts from a direct-Sun method, Langley-derived aerosol optical depths, and aerosol single-scattering albedos from a direct-to-diffuse irradiance ratio technique. Further comparisons were performed between the measurements and model simulations when using the retrieval results as inputs, both from the proposed technique and the combined independent methods. Simulations using the results of the new method were found to agree with the observations within the assumed limits of measurement and model uncertainty. It is anticipated that the technique will be applied across a 33-site network of radiometers maintained by the U. S. Department of Agriculture UV-B Monitoring and Research Program for development of aerosol climatologies and for providing ground validation for satellite measurements.

Both indices were calculated from 500 m spatial resolution Moderate Resolution Imaging Spectroradiometer (MODIS) reflectance data covering a 33-month period from 2000 to 2002. Both NDVI and NDWI were positively correlated with live fuel moisture measured by the Los Angeles County Fire Department (LACFD). NDVI had R-2 values ranging between 0.25 to 0.60, while NDWI had significantly higher R-2 values, varying between 0.39 and 0.80. Water absorption measures, such as NDWI, may prove more appropriate for monitoring live fuel moisture than measures of chlorophyll absorption such as NDVI.

Both percentages and the mean fluorescence intensity (MFI) of PMN expressing CD11a, CD44,CD62L, and LPAM-1 (alpha(4)beta(6)) were evaluated at seven time points during the twenty-one day period post calving. CD11a and CD62L were expressed on 94-100% of PMN in both blood and milk and there were no significant differences in these percentages at any time point. LPAM-1 was expressed on 3-10% of the PMN in the blood and 13-45% in the milk and the percentage of cells expressing LPAM-1 in milk was significantly (P < 0.05) greater than in blood at 0, 4, 10, 14, 18 and 21 days after calving. CD44 was expressed on 11-39% of the PMN in blood and 33-69% in the milk and the percentage of cells expressing CD44 in milk was significantly (P < 0.05) greater than in blood at all time points. The MFI of CD11a on milk PMN was consistently higher than that of blood PMN throughout the study period and significantly (P < 0.05) higher at days 4, 10 and 18 after calving.

One of these mAbs, 6D-12-G10, was found to recognize a conoid antigen of EA sporozoites and significantly inhibited the sporozoite invasions of host T lymphocytes in vitro. Furthermore, some of these chicken mAbs showed cross-reactivities with several different avian Eimeria spp. and the mAb 6D-12-G10 also demonstrated cross-reactivities with the tachyzoites of Neospora caninum and Toxoplasma gondii. Cryptosporidium spp. are coccidian parasites closely related to Eimeria spp., and especially C. parvum is an important cause of diarrhea in human and mammals. In the present study, to assess that the epitopes recognized by these chicken mAbs could exist on Cryptosporidium parasites, we examined the cross-reactivity of these mAbs with Cryptosporidium spp. using an indirect immunofluorescent assay (IFA) and Western blotting analyses. In IFA by chicken mAbs, the mAb 6D-12-G10 only showed a immunofluorescence staining at the apical end of sporozoites, of C. parvum and C. muris, and merozoites of C. parvum. Western blotting analyses revealed that the mAb 6D-12-G10 reacted with the 48-kDa molecular weight band of C. parvum and C muris oocyst antigens, 5D-11 reacted the 155 kDa of C. muris. Furthermore, these epitopes appeared to be periodate insensitive. These results indicate that the target antigen recognized by these chicken mAbs might have a shared epitope, which is present on the apical complex of apicomplexan parasites. (c) 2004 Elsevier B.V.

Treatment with PME reduced uronosyl concentrations from 97 to 92 mg/g, reduced uronosyl methylation from 57% to 21%, and increased Klason lignin concentrations in artificially lignified cell walls from 99 to 116 mg/g. Although PME treatment slightly enhanced uronosyl release from nonlignified cell walls, it reduced uronosyl release from artificially lignified cell walls by 55% after 4 h and by 7% after 72 h of enzymatic hydrolysis. Pectin hydrolysis in PME treated cell walls was probably impaired by enhanced benzyl ester cross-linking of uronosyls to lignin via quinone methide intermediates. Variations in uronosyl methylation had little effect on the overall release of total sugars from cell walls. C1 USDA ARS, US Dairy Forage Res Ctr, Madison, WI 53706 USA.

Near-infrared (NIR) reflectance spectroscopy, a rapid and environmentally benign technique, was investigated as a potential method for the prediction of total fat using AOAC method 996.01 as the reference method. Near-infrared reflectance spectra (1104-2494 nm) of ground cereal products (n = 72) were obtained using a dispersive spectrometer, and total fat was determined according to AOAC method 996.01. Using multivariate analysis, a modified partial least-squares model was developed for total fat prediction. The model had a SECV of 1.12% (range = 0.5-43.2%) and a multiple coefficient of determination of 0.99. The model was tested with independent validation samples (n = 36); all samples were predicted within NLEA accuracy guidelines. The results indicate that NIR reflectance spectroscopy is an accurate means of determining the total fat content of diverse cereal products for nutrition labeling.

Compositions of the resulting protein fractions were analyzed by RP-HPLC combined with SIDS-PAGE. Unknown proteins were identified by mass spectrometry or N-terminal sequencing. The best separation and recovery of discrete albumin/globulin, gliadin, and glutenin fractions from the same flour sample was achieved by extraction with 0.3 M Nal in 7.5% 1-propanol followed by 2% SIDS, 25 mM DTT in 25 mM TRIS, pH 8.0, and precipitation of the solubilized proteins with ammonium acetate/methanol followed by acetone. Average flour composition for the variety Butte86 was 10% album in/globulin, 40% gliadin, and 48% glutenin. This method should be useful for determining flour composition in diverse samples and evaluating relationships between proteins and end-use functionality.

Most research knowledge still resides in highly technical, narrowly focused research publications housed in libraries. The internet, combined with increasingly sophisticated hyperdocument authoring systems, makes web-based hyperdocuments a practical and affordable way to manage this scientific knowledge. The USDA Forest Service developed the Encyclopedia of Southern Appalachian Forest Ecosystems (ESAFE; http://www.forestencyclopedia.net), a hyperdocument-based encyclopedia system available on the internet, to address this need for more accessible, understandable, condensed, and synthesized research knowledge. This project aims to synthesize what we know scientifically about the management and ecology of Southern Appalachian forest ecosystems, organize it logically, and make it universally available at no cost to users. ESAFE is composed of original summaries of hundreds of topic areas compiled from over 5000 literature sources by over 15 authors specifically for this purpose. Presently, ESAFE has over 1100 pages of content that includes over 150 tables, 150 figures, 3000 internal hyperlinks, and 1800 external hyperlinks. Unlike most internet-based hyperdocuments, quality control of the encyclopedia is ensured through a complete peer-review process similar to traditional scientific journals. The encyclopedia is built upon a dynamic content management system (CMS), developed using Zope software, that provides a platform for authoring, editing, reviewing, publishing, and updating content directly through the internet. This CMS creates a mechanism for updating the site with peer-review content directly through the internet, so that the knowledge base can be continually updated, expanded, and improved. Using tools like ESAFE, busy forest managers can more easily find answers to questions from their own desks. It has been favorably evaluated by a diverse group of land managers, the general public, and ecosystem scientists. It is also currently being used as a prototype for several other forestry-related hypertext encyclopedias. (c) 2004 Elsevier B.V. All rights reserved.

Spatial patterns of forest structural conditions, tree species composition, snags and down wood, and temporal variation in these patterns, have been altered to such an extent that the natural ebb and flow of terrestrial habitats and their linkages has been disrupted. Closely coupled with these changes, fire and other disturbance processes in most dry and many mesic forest types have also shifted, with a bias for increased severity and extent. Here, in the context of planning restoration of some semblance of historical vegetation pattern-disturbance process interactions, we briefly revisit why it is theoretically sound to estimate the range and variation in historical forest spatial patterns. We call these estimates of range and variation, reference conditions or reference variation (RV), and discuss how forest managers might use them when evaluating current landscape patterns to identify changes that may have important ecological implications. We term such evaluations, departure analyses, and we describe how departure analysis is implemented in a decision support system (DSS) for integrated landscape evaluation and restoration planning. The initial phase of the DSS uses logic-based modeling to evaluate existing patterns of forest vegetation in subwatersheds of one ecoregion against a corresponding envelope of historical reference conditions for the same region, thereby highlighting key departures. The secondary planning phase uses results from the analysis phase in a decision model to prioritize watersheds for possible management actions related to landscape restoration and maintenance. We conclude from our example that there are at least two advantages to a decision-support approach that treats evaluation and planning as distinct but integrated phases: (1) the overall decision process is rendered conceptually simpler and (2) practical considerations of efficacy and feasibility of management actions can be easily accommodated.

Here, we report the production of transgenic alfalfa plants containing the genes encoding the polyprotein P1 and the protease 3C of foot and mouth disease virus (FMDV). The immunogenicity of the expressed products was tested using a mouse experimental model. Parenterally immunized mice developed a strong antibody response and were completely protected when challenged with the virulent virus. This report demonstrates the possibility of using transgenic plants to express polyprotein P1 and the protease 3C of FMDV and their utilization as effective experimental immunogens.

The addition of these materials also have positive impacts on soil phosphorus (P) availability. This study was conducted to investigate the effects of animal- and legume-based cropping systems in place for 5-13 years on the chemistry of organic matter and soil R Two cropping systems, Potato Ecosystem (ECO) located in Presque Isle, ME, U.S.A. and Grass Fertility (GF) located in Stillwater, ME, U.S.A. received animal manure. Two others, Liebman E Rotation (LER) in Stillwater, ME, U.S.A. and Porter Rotation (PR) in Presque Isle, ME, U.S.A. were primarily legume-based rotations. Estimated difference in carbon input (ha(-1) year(-1)) between the amended and control plots were: ECO, 8 100 kg C; GF, 1010 kg; LER, 950 kg C; and PR, 415 kg C. The dissolved organic carbon (DOC) concentration was higher (P < 0.10) in the treatment that received animal manure than those which only received legume residue. The E2/E3 spectrophotometric test indicated that the DOC extracted from the ECO manure-treated plots was more humified than that from the ECO control plots. There were no significant differences between the amended and control treatments in Olsen P or total P for all the tested cropping systems. Similar to that of the DOC response, the ECO cropping system that received animal manure recorded higher concentrations of water soluble P (P < 0.05). There was a linear relationship between DOC and water-soluble P concentrations of the soil:water extract across soils, indicating a positive relationship between them. To determine the effects of the different cropping systems on P bioavailability, a simulation model was used to study how changes in P soil chemistry may affect P uptake by crops. The simulation runs showed that predicted P uptake was greater for the animal manure based ECO and GF systems, but not for the legume based LER and PR systems (P < 0.05). This study shows that cropping systems that include animal manure may increase soil P availability. (c) 2004 Elsevier B.V. All rights reserved.

In our model system, tobacco cell suspensions treated with bacterial isolate Pseudomonas syringae WT (HR+) undergo a resistant interaction characterized by a burst in oxygen uptake several hours after inoculation. When the extracellular concentration of acetosyringone in tobacco cell suspensions was supplemented with exogenous acetosyringone, the burst in oxygen uptake occurred as much as 1.5 h earlier. The exogenous acetosyringone had no effect on tobacco suspensions undergoing susceptible interactions with Pseudomonas tabaci or a non-resistant interaction with a near-isogenic mutant derivative of isolate P. syringae WT (HR+). Resistant interactions with isolate P. syringae WT (HR+) also produce an oxidative burst which oxidizes the extracellular acetosyringone. This study demonstrates that acetosyringone, and likely other extracellular phenolics, may have bioactive characteristics that can influence plant-bacterial pathogenesis. Published by Elsevier Inc.

Some methods use empirical infiltration functions, such as the Kostiakov equation. Others use physically based infiltration functions, such as the Green-Ampt equation. Another option is to use the Richards equation, describing the one-dimensional vertical infiltration of water into the soil for a specified irrigation event. This equation is generally accepted to provide a basis for comparison between other runoff estimation methods. [P.B. Luz, J.C. Martins, M.C. Gongalves, Reliable estimate of runoff in center pivot irrigation: statistical approach, in: Proceedings of the 16 Congress Mondial de Science du Sol, Poster 2-658, ISSS, Montpellier, France, August 19-25, 1998, pp. 577-593], developed a conceptual method of statistical nature, to estimate potential runoff in center pivot irrigation, comprising regression equations built with runoff results from a simulation computer model using the Richards equation. The procedure to simulate runoff involved a wide set of data related to water retention parameters and soil texture [W.J. Rawls, D.L.

Such regression equations present a dependent variable, defined as an index of four parameters, related to the center pivot irrigation and to the soil-water system evaluation. The method had unacceptable results when a crust developed on the soil surface. Therefore, the objective of this study was to redefine the index, establishing new parameter coefficients with a trial and error approach. The model efficiency (similar to the coefficient of determination, r(2)) ranged from 90 to 98%, showing the results are in good agreement to those computed by Richards equation, exhibiting a strong predictive value.

In soybeans ( a dicotyledonous legume), the vspA and B genes encode subunits of a dimeric vegetative storage protein that plays an important role in nitrogen storage in vegetative tissues. Similar genes are found in monocots; however, they do not accumulate in leaves as storage proteins, and the ability of monocot leaves to support accumulation of an ectopically expressed soybean VSP is in question. To test this, transgenic maize ( Zea Mays L. Hi-II hybrid) lines were created expressing soybean vspB from a maize ubiquitin Ubi-I promoter. Results: From 81 bombardments, 101 plants were regenerated, and plants from five independent lines produced vspB transcripts and VSP beta polypeptides. In leaves from seven-week-old plants ( prior to flowering), VSP beta accumulated to 0.5% of the soluble leaf protein in primary transgenic plants ( R-0), but to only 0.03% in R-1 plants. During seed-filling ( silage-stage) in R-1 plants, the VSP beta protein was no longer detected in leaves and stems despite continued presence of the vspB RNA. The RNA transcripts for this peptide either became less efficiently translated, or the VSP beta protein became unstable during seed-fill. Conclusion: Developmental differences in the accumulation of soybean VSP beta when transgenically expressed in maize show that despite no changes in the vspB transcript level, VSP beta protein that is readily detected in leaves of preflowering plants, becomes undetectable as seeds begin to develop.

Exposure to these particles can affect the ability of rats to perform a variety of tasks, indicating that there is the possibility that the performance capabilities of astronauts may be affected. Previous research has shown that diets containing blueberry or strawberry extract can ameliorate the deficits produced by irradiation using a ground-based analog for exposure to cosmic rays. Rats were placed on diets containing 2% blueberry or strawberry extract for 2 months prior to exposure to 1.5 Gy of 1 GeV/n 56 Fe particles. There were no effects on performance of any group of animals when tested on an ascending fixed-ratio operant task 6 months following exposure. When tested 12 months after exposure, the performance of the radiated animals given blueberry extract did not differ from the radiated animals fed the control diet. Both groups performed significantly poorer than the non-irradiated controls. There were no differences between the non-irradiated animals fed control diet and the radiated animals fed the strawberry diet and their performance was significantly better than of the radiated rats fed the blueberry or control diets. The results indicate that diets containing strawberry extract may provide a significant level of radiation protection on exploratory class missions. (c) 2005 Elsevier B.V. All rights reserved.

To date, blueberries have proved most effective at improving measures of motor performance, spatial learning and memory, and neuronal functioning in old rats. In an effort to further characterize the bioactive properties of fruits rich in color and correspondingly high in anthocyanins and other polyphenolics, 19-month-old male Fischer rats were fed a well-balanced control diet, or the diet supplemented with 2% extract from either blueberry, cranberry, blackcurrant, or Boysenberry fruit for eight weeks before testing began. The blackcurrant and cranberry diets enhanced neuronal signal transduction as measured by striatal dopamine release, while the blueberry and cranberry diets were effective in ameliorating deficits in motor performance and hippocampal HSP70 neuroprotection; these changes in HSP70 were positively correlated with performance on the inclined screen. It appears that the polyphenols in blueberries and cranberries have the ability to improve muscle tone, strength and balance in aging rats, whereas polyphenols in blueberries, cranberries and blackcurrants have the ability to enhance neuronal functioning and restore the brain's ability to generate a neuroprotective response to stress.

Irradiation produced a disruption of operant responding in rats tested 5 and 8 months after exposure, which was prevented by maintaining the rats on a diet containing strawberry, but not blueberry, extract. When tested 13 and 18 months after irradiation there were no differences in performance between the radiated rats maintained on control, strawberry or blueberry diets. These observations suggest that the beneficial effects of antioxidant diets may be dependent upon the age of testing. C1 Univ Maryland Baltimore Cty, Dept Psychol, Baltimore, MD 21250 USA.

Our objective was to examine how fallowing affects soil organic carbon (SOC) in various agronomic and climate settings by reviewing long-term studies in the midwestern USA (five sites) and the Canadian prairies (17 sites). In most soils, SOC increased with cropping frequency though not usually in a linear fashion. In the Canadian studies, SOC response to tillage and cropping frequency varied with climate-in semiarid conditions, SOC gains under no-till were about 250 kg ha(-1) yr(-1) greater than for tilled systems regardless of cropping frequency; in subhumid environments, the advantage was about 50 kg ha-1 yr-1 for rotations with fallow but 250 kg ha(-1) yr(-1) with continuous cropping. Specific crops also influenced SOC: Replacing wheat (Triticum aestivum L.) with lentil (Lens culinaris Medikus) had little effect; replacing wheat with lower-yielding flax (Linum usitatismum L.) reduced SOC gains; and replacing wheat with erosion-preventing fall rye (Secale cereale L.) increased SOC gains. In unfertilized systems, cropping frequency did not affect SOC gains, but in fertilized systems, SOC gains often increased with cropping frequency. In a Colorado study (three sites each with three slope positions), SOC gains increased with cropping frequency, but the response tended to be highest at the lowest potential evaporation site (where residue C inputs were greatest) and least in the toeslope positions (despite their high residue C inputs). The Century and the Campbell et al. SOC models satisfactorily simulated the relative responses of SOC although they underestimated gains by about one-third.

The purpose of this paper is to review research on water use efficiency and precipitation use efficiency (PUE) as affected by cropping system and management in the Great Plains. Water use efficiency and PUE increase with residue management practices that increase precipitation storage efficiency, soil surface alterations that reduce runoff, cropping sequences that minimize fallow periods, and use of appropriate management practices for the selected crop. Precipitation use efficiency on a mass-produced basis is highest for systems producing forage (14.5 kg ha(-1) mm(-1)) and lowest for rotations with a high frequency of oilseed crops (4.2 kg ha(-1) mm(-1)) or continuous small-grain production in the southern plains (2.8 kg ha(-1) mm(-1)). Precipitation use efficiency when calculated on a price-received basis ranges from $1.20 ha(-1) mm(-1) (for an opportunity-cropped system with 4 of 5 yr in forage production in the southern plains) to $0.30 ha(-1) mm(-1) {for a wheat (Triticum aestivum L.)-grain sorghum [Sorghum bicolor (L.) Moench]-fallow system in the southern plains}. Throughout the Great Plains region, PUE decreases with more southern latitudes for rotations of similar makeup of cereals, pulses, oilseeds, and forages. Forage systems in the southern Great Plains appear to be highly efficient when PUE is computed on a price-received basis. In general across the Great Plains, increasing intensity of cropping increases PUE on both a massproduced basis and on a price-received basis.

Broadscope problems associated with developing sustainable cropping systems are how to choose and sequence crops in cropping systems. Our objectives were twofold: (i) evaluate impacts of crop sequencing on precipitation use and (ii) show how crop sequencing can accentuate synergistic interactions among crops. Crop-fallow systems that developed in the Great Plains resulted in precipitation storage efficiencies of about 20% in the early 1930s to about 40% in the late 1980s. Integrated crop-livestock systems have been developed in the southern Great Plains to take advantage of bimodal annual precipitation pattern to produce high quality pigeonpea [Cajanus cajan (L.) Millsp.] forage during the noncrop period between winter wheat (Triticum aestivum L.) harvest and seeding. Pigeonpea can be grown after a mid-June winter wheat harvest since pigeonpea uses precipitation received from wheat harvest to late September and pigeonpea has a root system that allows it to use soil water below the effective rooting depth of wheat. In the central Great Plains, water-use efficiency of winter wheat was improved 18 to 56% by including broadleaf crop in a grass-based rotation. Cropping systems in the northern Great Plains tend to be more diverse, and research at Mandan, ND, suggests that seed yield of flax (Linum usitatissium L.) can be tripled with a safflower (Carthamus tinctorius L.)-flax crop sequence vs. a flax-flax crop sequence. Great Plains cropping systems of the future will not only need to take advantage of crop sequences through synergism, but also take advantage of the interactions associated with diversity in space (polyculture).

At each site, a randomized complete block design with a factorial arrangement of treatments replicated four times was used. Treatments were multiple effluent irrigations resulting in four N rates from 0 to 665 kg N ha(-1) yr(-1). In each block, commercial fertilizer (N, P, and K) treatments were applied to additional plots at rates equivalent to swine effluent rates. Total dry matter yield and crude protein (CP) for bermudagrass and johnsongrass reached a plateau with application of approximately 450 kg N ha-1 from either swine effluent or commercial fertilizer. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) peaked at the low fertilization rate and then declined with increasing effluent and commercial fertilizer rates. An inverse relationship was obtained for in vitro true digestibility (IVTD) in response to fertilization rate for both grasses. Forage dry matter, CP, NDF, and ADF levels peaked in the July harvest and then declined, but forage IVTD level declined in July harvest. Only in July 1996, forage NO3-N concentration was lower for swine effluent than commercial fertilizer. Swine effluent and commercial fertilizer had similar effects on forage dry matter yield and nutritive value. C1 USDA, ARS, Waste Manage & Forage Res Unit, Mississippi State, MS 39762 USA.

This study derived maize (Zea mays L.) leaf area index (LAI) estimates from spectral data and used these estimates with a simple LAI-based yield model to forecast yield under irrigated conditions in large areas in Sinaloa, Mexico. Leaf area index was derived from satellite data with the use of an equation developed with LAI measurements from farmers' fields during the 2001-2002 autumn-winter growing season. These measurements were correlated with the normalized difference vegetation index values from 2002 Landsat ETM+ (enhanced thematic mapper) data. The equation was then tested with 2003 Landsat imagery data. A yield model was validated with maximum LAI and yield data measured in farmers' fields in northern and central Sinaloa during three consecutive autumn-winter growing seasons (1999-2000, 2000-2001, and 2001-2002). The yield model was further validated with 2002-2003 autumn-winter ground LAI (gLAI) and satellite-derived LAI (sLAI) data from 71 farmers' fields in northern and central Sinaloa. Grain yield was predicted with a mean error of -9.2% with maximum gLAI and -11.2% with sLAL Results indicate that the yield model using LAI can forecast yield in large areas in Sinaloa in the middle of the growing season with a mean absolute error of -1.2 Mg ha(-1). The use of sLAI in place of ground measurements increased the mean absolute error by 0.3 Mg ha(-1). Nevertheless, the use of sLAI would eliminate laborious LAI measurements for large-area yield prediction in Sinaloa. C1 INIFAP, Lab Nacl Modelaje & Sensores Remotos, Aguascalientes 20660, Mexico.

Unfortunately, temperature responses of models often are not examined critically to ensure that a model is appropriate for a given research application. This paper describes a procedure for assessing how models respond to temperature. The procedure treats major processes in a balanced fashion but does not require access to source code. The results are easily interpretable by nonmodelers and readily documented and employed with different models. Sensitivity analyses are run using standardized conditions of nonlimiting water and N with regimes of constant mean temperatures from 3 to 40 degrees C and daily range of 10 degrees C. Daily model outputs define responses that are grouped in seven Categories: crop mass (including economic yield), phenology, reproductive growth, canopy development, root growth, resource use efficiency, and water balance. To avoid interactions of duration of life cycle with growth, several responses are assessed before partitioning to reproductive growth reduces total aboveground biomass. Emphasis is on graphical analysis of individual variables vs. mean temperature, but cardinal temperatures and a response index are also estimated. When applied to the CSM-CERES-Sorghum and CSM-CROPGRO-Drybean models, the procedure readily identified differences in temperature adaptation of the two crops. Various examples were found where modeled responses appeared to differ from data from field or controlled-environment studies. The proposed procedure will require adjustments for specific situation but provides a foundation for assessing modeled responses to temperature in a structured and reproducible fashion.

Understanding variability in need for N fertilizer within individual fields is necessary to guide approaches to meeting crop needs while minimizing N inputs and losses. Our objective was to characterize the spatial variability of corn (Zea mays L.) N need in production corn fields. Eight experiments were conducted in three major soil areas (Mississippi Delta alluvial, deep loess, claypan) over 3 yr. Treatments were field-length strips of discrete N rates from 0 to 280 kg N ha(-1). Yield data were partitioned into 20-m increments, and a quadratic-plateau function was used to describe yield response to N rate for each 20-m section. Economically optimal N fertilizer rate (EONR) was very different between fields and was also highly variable within fields. Median EONR for individual fields ranged from 63 to 208 kg N ha(-1), indicating a need to manage N fertilizer differently for different fields. In seven of the eight fields, a uniform N application at the median EONR would cause more than half of the field to be over- or underfertilized by at least 34 kg N ha-1. Coarse patterns of spatial variability in EONR were observed in some fields, but fine and complex patterns were also observed in most fields. This suggests that the use of a few appropriate management zones per field might produce some benefits but that N management systems using spatially dense information have potential for greater benefits. Our results suggest that further attempts to develop systems for predicting and addressing spatially variable N needs are justified in these production environments.

Pers.] in manure nutrient management is limited to summer haying. This study was done to determine how hay yield and nutrient uptake in a manure-fertilized Tifton 44 field were affected by fall overseeding and spring haying with berseem clover (Trifolium alexandrinum L.), crimson clover (T. incarnatum L.), annual ryegrass (Lolium multiflorum L.), and wheat (Triticum aestivum L.). Overseeding treatments were compared with a nonoverseeded control on Mantachie loam (fine, siliceous, acid, thermic Aeric Fluvaquents) receiving 168 kg P ha(-1) in swine (Sus scrofa domesticus) effluent. Spring hay was cut April-June and summer hay July-October 2000-2002. Dry matter (DM) (4.4-5.5 Mg ha(-1) yr(-1)) and P uptake (12.2-17.1 kg ha(-1) yr(-1)) of spring berseem clover hay were higher than the control in 2 of 3 yr and higher than other treatments in 2002. Total DM and P uptake with berseem clover overseeding were 10% higher than the control. Final Mehlich-3 P soil levels (0-5 cm) tended to be lower in the berseem clover treatment than the control (65 vs. 81 mg kg(-1), respectively). Spring berseem clover hay was higher in N (94-122 kg ha(-1) yr(-1)) than the control each year and higher than other treatments in 2 of 3 yr. Summer Tifton 44 hay in the berseem clover treatment had more DM in 2002 and higher N uptake in 2001 and 2002 than other treatments. No treatment reduced Tifton 44 yield or nutrient uptake. Overseeding increased hay yield and nutrient uptake, and berseem clover was as good as or better than other treatments.

Pers.] is commonly used to manage field-applied manure P in the southeastern USA but is limited to summer. This 3-yr study was done to examine effects of extending the haying season by spring haying of fall-overseeded annuals. Berseem clover (Trifolium alexandrinum L.), crimson clover (T. incarnatum L.), annual ryegrass (Lolium multiflorum L.), and wheat (Triticum aestivum L.) were compared with a nonoverseeded control. Dry matter (DM) yield and N and P uptake were measured in spring and summer hay on a Prentiss sandy loam (coarseloamy, siliceous, thermic Glossic Fragiudults, Ultisols) with high soil P following 6 yr of swine (Sus scrofa domesticus) effluent fertilization. Fall-seeded plots were cut twice for spring hay and three times for summer hay. Spring hay of annual ryegrass (3.8-5.3 Mg ha(-1) yr(-1)) yielded more DM than crimson clover (2.6-3.4 Mg ha(-1) yr(-1)), wheat (2.5-3.3 Mg ha(-1) yr(-1)), and the control (2.8-3.4 Mg ha(-1) yr(-1)) every year but did not differ from berseem clover (3.1-4.6 Mg ha(-1) yr(-1)) in 2 of 3 yr. Phosphorus uptake in spring hay of annual ryegrass and berseem clover (10-16 kg ha(-1)) was higher than crimson clover (8-12 kg ha(-1)), wheat (7-12 kg ha(-1)), and the control (6-11 kg ha(-1)). Nitrogen uptake in spring hay was higher in berseem clover (71-128 kg ha(-1)) than other treatments (43-80 kg ha(-1)), which did not differ. No differences occurred in summer hay (DM = 3.9-7.6 Mg ha(-1), N = 72-191 kg ha(-1), P = 13-21 kg ha(-1)). Overseeding common bermudagrass with berseent clover or annual ryegrass can improve hay yield and P removal.

The objectives of this research are to determine if 15.5 degrees C is an accurate lower-threshold temperature to monitor the boll maturation period (BMAP) for cotton in the northern, rainfed region of the U.S. Cotton Belt, to investigate other climatic factors in this cotton region that may improve the accuracy of the current degree day system for cotton, and to evaluate degree day models that include both an upper- and lower-threshold temperature. Cotton was planted at three different timings in 2001 and 2002 to provide different climatic regimes during the BMAP. On 10 typical plants per plot, all first-position flowers were individually tagged with date of flower opening and were then harvested at full maturity. Daily weather data consisted of maximum, minimum, and average air temperature; maximum and average soil temperature; average soil moisture; maximum and average solar radiation; and maximum and average photosynthetically active radiation. The 17 degrees C degree day model, which used 17 degrees C as the lower threshold, provided the best adjusted r(2) (0.2715) of all the single-variable models; the degree day 15.5 degrees C model had an adjusted r(2) of 0.2276. The best model using both upper and lower temperature thresholds was DD3017, using 30 and 17 degrees C as the thresholds, and had an adjusted r2 of 0.2452. Adding average, minimum, and maximum air temperatures to the DD15.5, DD17, and DD3017 models reduced coefficient of variation and mean square error and increased adjusted r(2) values.

An incubation study was conducted to determine P availability from swine (Sus scrofa) and cattle (Bos taurus) feedlot manure in three soils. Treatments for each manure included temperature (11, 18, 25, and 32 degrees C), water regime [constant 60% water-filled pore space (WFPS) vs. four dry-down cycles of 60 to 30% WFPS], time, and soils (Catlin silt loam, Sharpsburg silty clay loam, and Valentine fine sand). In another study, synthetic P fertilizer was used to determine the fraction of P that becomes unavailable with time to compare with manure P. Time, soil, and manure application were factors that influenced soil test P and water-soluble P during incubation. At the low synthetic P fertilizer rate of 6 mu g g(-1), about 12 kg P ha(-1), none of the applied P remained available in the Catlin soil while about one-third remained plant available in the Sharpsburg soil and two-thirds in the Valentine soil. At the high P rate, 68 mg kg(-1), 38 to 83% of fertilizer P remained available in the three soils. Phosphorus availability was 60 to 100% of applied cattle manure P and 52 to 100% of swine slurry P in the three soils. Phosphorus availability in the Sharpsburg soil was 100% of P in both manure types. Phosphorus availability from manure is high, and manure can be used similar to inorganic P fertilizer in soils where P-based application is made in areas susceptible to P loss in runoff. In P-deficient soils, a P availability of 70% should be used. C1 USDA ARS, Clay Ctr, Lincoln, NE 68583 USA. RP Wienhold, BJ (reprint author), USDA ARS, Clay Ctr, Lincoln, NE 68583 USA.

Biomass yield and survival percentage in western North Dakota were measured for 3 yr at three field sites, and plant development was monitored for 2 yr at one site to determine adaptation and stability of performance for eight diverse switchgrass cultivars and experimental strains. Harvest treatments were single annual cuttings in mid-August or mid-September. Except for 'Dacotahl, ND3743, and 'Sunburst', all other entries originated greater than 500 km south of the evaluation sites and were subject to winter injury. Sunburst, from southern South Dakota, ranked first or second in biomass yield in all environments and was the top-yielding entry in all environments in the third production year, a drought year at all sites. 'Trailblazer' ranked first, second, or third in biomass yield in all environments while yield ranking of the other entries was not consistent. Genotype x environment interactions occurred for biomass yield and would be expected based on the wide range in origin among the eight populations. Survival percentage was equal for the two harvest dates, but all eight populations averaged greater biomass yields at the mid-September (5.98 Mg ha(-1)) than the mid-August (5.51 Mg ha(-1)) harvest. Biomass yield of Sunburst at the site with the greatest yield potential ranged from 3.20 Mg ha(-1) in a drought year to 12.48 Mg ha(-1) in a year with above average precipitation. Biomass yield of adapted switchgrass cultivars fluctuated widely in western North Dakota, depending in large part on available soil water. C1 USDA ARS, No Great Plains Res Lab, Mandan, ND 58554 USA.

Our hypothesis was that integrating crop and livestock systems would reduce irrigation water use, maintain profitability, and diversify income compared with a cotton (Gossypium hirsutum L.) monoculture. Thus, from 1998 to 2002, two large-scale systems, with three replications in a randomized block design, compared water use, productivity, and economics of (i) a cotton (var 'Paymaster 2326RR') monoculture with terminated wheat (Triticum aestivum L.) and (ii) an integrated three-paddock system that included cotton in a twopaddock rotation with grazed wheat and rye (Secale cereale L.) and the perennial IWW-B. Dahl' old world bluestem [Bothriochloa bladhii (Retz) S.T. Blake] for grazing and seed production. All paddocks were irrigated by subsurface drip. Angus crossbred beef steers (Bos taurus L.; initial body weight = 249 kg; standard deviation = 26 kg) grazed from January to mid-July. During the 4 yr of this experiment following the establishment year, cotton lint yield was 1036 and 1062 kg ha(-1) for the cotton monoculture and the integrated system, respectively. Bluestem seed yield averaged 24 kg pure live seed ha(-1). Steers gained 153 kg on pasture and 0.82 kg d(-1). Per hectare, the integrated system used 23% less (P < 0.001) irrigation water, 40% less N fertilizer, and fewer other chemical inputs than the cotton monoculture. Profitability was about 90% greater for the integrated system at described conditions. Integrated production systems that are less dependent dent on irrigation and chemical inputs appear possible while improving profitability.

Field studies were conducted near Stoneville, MS (33 degrees 26' N lat.), to determine the effect of rotating maturity group (MG) IV and V glyphosate [N-(phosphonomethyl)glycine]-resistant (GR) and non-GR cultivars on weed populations, soybean seed yields, and net returns from nonirrigated plantings. Eight management systems, each containing a MG IV or MG V GR or non-GR cultivar grown continuously or in rotation with each other, and two weed management treatments [pre-emergent followed by postemergent weed management (PRE + POST) and postemergent-only weed management (POST)] were grown each year. Glyphosate-resistant cultivars using POST-only glyphosate was the most economical system each year. Maturity group effect on yield and net return resulted from weather differences during reproductive development. Rotating GR and non-GR cultivars had no consistent effect on weed populations and no significant effect on yield or net return in this 4-yr study. Using GR cultivars resulted in net returns that were greater than those from non-GR cultivars. These results indicate that production systems using either GR or non-GR cultivars grown continuously or in rotation with each other in this region can be utilized effectively with no effect on weed population shifts or reductions in seed yield and net return.

We addressed this hypothesis by comparing microhabitats of two pairs of congeners that differ in habitat specificity and co-occur in one distinct habitat type, Florida rosemary scrub. We characterized microhabitats of rosemary scrub specialists, Polygonella basiramia and Lechea cernua, their habitat-generalist congeners, Polgonella robusta and Lechea deckertii, and random points in the rosemary scrub habitat. Plants of both habitat specialists occurred in microhabitats with significantly more bare sand than plants of habitat-generalist species and random points. Plants of all four species Occurred in microhabitats that were farther from dominant shrubs, Ceratiola and Quercus spp., than random points. Seedlings of both habitat specialists grew larger in bare sand microhabitats, whereas ground lichens and litter did not affect seedling growth of the habitat generalists. As the time since fire increases, bare sand cover decreases, Ceratiola density increases, Quercus density remains constant, and shrubs become taller. Physical characteristics, such as soil temperature, soil carbon, and soil moisture, differ slightly with respect to microhabitat. Our results suggest that P. basiramia and L. cernua are specialized on bare sand microbabitats that characterize their preferred habitat, rosemary scrub. Microhabitat specialization may limit the distribution of these rare species. C1 Louisiana State Univ, Dept Sci Biol, Baton Rouge, LA 70803 USA. Archbold Biol Stn, Lake Placid, FL 33862 USA.

Data are limited on circulating folate concentrations in pregnant African American women after folic acid fortification of the food supply was implemented. Objective: The objective was to determine the influence of smoking and alcohol consumption on plasma 5-methyltetrahydrofolic acid (5-MTHFA) concentrations in pregnant African American women. Design: Alcohol consumption, smoking exposure, and other characteristics of pregnant African American women reporting to an inner-city antenatal clinic were assessed. At 24 wk of gestation, blood samples and food-frequency intake data were collected. Plasma 5-MTHFA concentrations were determined by liquid chromatography-mass spectrometry for 116 subjects and examined in a correlational study design. Results: Dietary folate and markers of alcohol consumption were positively associated, whereas exposure to smoke was negatively associated with plasma 5-MTHFA. More than one-half of the participants in this population failed to meet the recommended dietary allowance for dietary folate equivalents of 600 mu g/d during pregnancy. Conclusions: Most inner-city African American women are not meeting the recommended dietary allowance for dietary folate during pregnancy, and smoking may further compromise their folate status. Programs to reduce smoking and raise awareness about the importance of folate and multivitamin supplementation during pregnancy need to target this population.

ID ASCORBIC-ACID CONTENT; SOLANUM-TUBEROSUM L; VITAMIN-C RETENTION; ANTHOCYANIN PIGMENTATION; NUTRIENT COMPOSITION; CAROTENOID CONTENT; CULTIVATED POTATO; TOTAL PHENOLICS; VEGETABLES; CAPACITY AB The content of compounds in potato that may act as antioxidants in the human diet is not widely appreciated. Carotenoids are present in the flesh of all potatoes. The contents mentioned in the literature range from 50 to 100 mu g per 100 g fresh weight (FW) in white-fleshed varieties to 2000 mu g per 100 g FW in deeply yellow to orange-fleshed cultivars. The carotenoids in potato are primarily lutein, zexanthin, and violaxanthin, all of which are xanthophylls. There is just a trace of either alpha- or beta-carotene, meaning that potato is not a source of pro-vitamin A carotenes. In potatoes with total carotenoids ranging from 35 to 795 mu g per 100 g FW, the lipophilic extract of potato flesh presented oxygen radical absorbance capacity (ORAC) values ranging from 4.6 to 15.3 nmoles alpha-tocopherol equivalents per 100 g FW. Potatoes contain phenolic compounds and the predominant one is chlorogenic acid, which constitutes about 80% of the total phenolic acids. Up to 30 mu g per 100 g FW of flavonoids are present in the flesh of white-fleshed potatoes with roughly twice the amount present in red- and purple-fleshed potatoes. The predominant flavonoids are catechin and epicatechin. Red and purple potatoes derive their color from anthocyanins. The skin alone may be pigmented, or the flesh may be partially or entirely pigmented. Whole unpeeled with complete pigmentation in the flesh may have up to 40 mg per 100 g FW of total anthocyanins. Red-fleshed potatoes have acylated glucosides of pelargonidin while purple potatoes have, in addition, acylated glucosides of malvidin, petunidin, peonidin, and delphinidin. The hydrophilic antioxidant activity of solidly pigmented red or purple potatoes is comparable to brussels sprouts or spinach. In red and purple potatoes with solidly pigmented flesh with levels of total anthocyanin ranging from 9 to 38 mg per 100 g FW, ORAC ranged from 7.6 and 14.2 umole per g FW of Trolox equivalents. Potato contains on average 20 mg per 100 g FW of vitamin C, which may account for up to 13 % of the total antioxidant capacity. Potatoes should be considered vegetables that may have high antioxidant capacity depending on the flesh composition. C1 USDA ARS, Prosser, WA 99350 USA.

The oxidative voltammetric signal resulting from the presence of tyrosine and tryptophan in avidin was observed using square-wave voltammetry. The process could be used to determine avidin concentrations up to 3 fM (100 amol in 3 mu l drop) in solution, 700 fM (174 fmol in 250 mu l solution) in an avidin-modified electrode, and 174 nM in a maize seed extract. In the case of the avidin-modified CPE, several parameters were studied in order to optimize the measurements, such as electrode accumulation time, composition of the avidin-modified CPE, and the elution time of avidin. In addition, the avidin-modified electrode was used to detect biotin in solution (the detection limit was 7.6 pmol in a 6 mu l drop) and to detect biotin in a pharmaceutical drug after various solvent extraction procedures. Comparable studies for the detection of biotin were developed using HPLC with diode array detection (HPLC- DAD) and flow injection analysis with electrochemical detection, which allowed biotin to be detected at levels as low as 614 pM and 6.6 nM, respectively. The effects of applied potential, acetonitrile content, and flow rate of the mobile phase on the FIA-ED signal were also studied.

The method uses a simple solvent extraction, dispersive solid-phase extraction (dispersive SPE) cleanup, and liquid chromatography-tandem mass spectrometry (LC/MS/MS) for confirmation and quantitation. Dispersive-SPE greatly simplifies and accelerates sample cleanup and improves overall recoveries compared with conventional SPE cleanup. The beta-lactam antibiotics tested were as follows: deacetylcephapirin (an antimicrobial metabolite of cephapirin), amoxicillin, desfuroylceftiofur cysteine disulfide (DCCD, an antimicrobial metabolite of ceftiofur), ampicillin, cefazolin, penicillin G, oxacillin, cloxacillin, naficillin, and dicloxacillin. Average recoveries of fortified samples were 70% or better for all beta-lactams except DCCD, which had an average recovery of 58%. The LC/MS/MS method was able to demonstrate quantitative recoveries at established tolerance levels and provide confirmatory data for unambiguous analyte identification. The method was also tested on 30 incurred bovine kidney samples obtained from the USDA Food Safety and Inspection Service, which had previously tested the samples using the approved semiquantitative microbial assay. The results from the quantitative LC/MS/MS analysis were in general agreement with the microbial assay for 23 samples although the LC/MS/MS method was superior in that it could specifically identify which beta-lactam was present and quantitate its concentration, whereas the microbial assay could only identify the type of beta-lactam present and report a concentration with respect to the microbial inhibition of a penicillin G standard. In addition, for 6 of the 23 samples, LC/MS/ MS analysis detected a penicillin and a cephalosporin beta-lactam, whereas the microbial assay detected only a penicillin beta-lactam. For samples that do not fall into the "general agreement" category, the most serious discrepancy involves two samples where the LC/MS/MS method detected a violative level of a cephalosporin beta-lactam (deacetylcephapirin) in the first sample and a possibly violative level of desfuroylceftiofur in the second, whereas the microbial assay identified the two samples as having only violative levels of a penicillin beta-lactam.

The objective of this research was to assess the structure of genetic diversity within and among the four cultivated alkaloid-bearing taxa of Erythroxylum in the living collection at Beltsville Agricultural Research Center. Methods Amplified fragment length polymorphism (AFLP) fingerprinting was performed in 86 Etythroxylum accessions using a capillary genotyping system. Cluster analysis, multidimensional scaling (MDS) and analysis of molecular variance (AMOVA) were used to assess the pattern and level of genetic variation among and within the taxa. Key Results A clear distinction was revealed between E. coca and E. novogranatense. At the intra-specific level, significant differentiation was observed between E. c. var. coca and E. c. var. ipadu, but the differentiation between E. n. var. novogranatense and E. n. var. truxillense was negligible. Erythroxylum c. var. ipadu had a significantly lower amount of diversity than the E. c. var. coca and is genetically different from the E. c. var. ipadu currently under cultivation in Colombia, South America. Conclusions There is a heterogeneous genetic structure among the cultivated Erythroxylum taxa where E. coca and E. novogranatense are two independent species. Erythroxylum coca var. coca is most likely the ancestral taxon of E. c. var. ipadu and a founder effect may have occurred as E. c. var. ipadu moved from the eastern Andes in Peru and Bolivia into the lowland Amazonian basin. There is an indication of artificial hybridization in coca grown in Colombia. (C) 2005 Annals of Botany Company. C1 USDA ARS, PSI, ACSL, Beltsville, MD 20705 USA.

Phylogeographic analysis of mitochondrial cytochrome oxidase I sequence variation indicates that L. sativae harbors distinct mitochondrial clades suggestive of the presence of cryptic species. Two of the major mitochondrial clades exhibited polyphagy, with members feeding on hosts in at least three plant families. Only one of the major clades was present in introduced populations, causing total mitoebondrial variation exhibited by introduced populations to be considerably reduced compared with that observed within the native range.

Two groups of related species were identified by neighbor-joining and maximum-parsimony analysis. One group consisted of Mesorhizobium loti and Mesorhizobium ciceri, and the other group consisted of Agrobacterium rhizogenes, Rhizobium tropici, Rhizobium etli, and Rhizobium leguminosarum. Although bootstrap support for the placement of the remaining six species varied, A. tumefaciens, Agrobacterium rubi, and Agrobacterium vitis were consistently associated in the same subcluster. The three other species included Rhizobium galegae, Sinorhizobium meliloti, and Brucella ovis. Among these, the placement of R. galegae was the least consistent, in that it was placed flanking the A. rhizogenes-Rhizobium cluster in the dnaK nucleotide sequence trees, while it was placed with the other three Agrobacterium species in the 16S rRNA and the DnaK amino acid trees. In an effort to explain the inconsistent placement of R. galegae, we examined polymorphic site distribution patterns among the various species. Localized runs of nucleotide sequence similarity were evident between R. galegae and certain other species, suggesting that the R. galegae genes are chimeric. These results provide a tenable explanation for the weak statistical support often associated with the phylogenetic placement of R. galegae, and they also illustrate a potential pitfall in the use of partial sequences for species identification.

Here, the interaction of Salmonella enterica serovar Thompson with a soilborne Tetrahymena sp. isolate was examined using serovar Thompson cells labeled with the green fluorescent protein. The bacteria were mixed in solution with cells of Tetrahymena at several ratios. During incubation with serovar Thompson, Tetrahymena cells released a large number of vesicles containing green fluorescent serovar Thompson cells. In comparison, grazing on Listeria monocytogenes cells resulted in their digestion and thus the infrequent release of this pathogen in vesicles. The number of serovar Thompson cells per vesicle increased significantly as the initial ratio of serovar Thompson to Tetrahymena cells increased from 500:1 to 5,000:1. The density of serovar Thompson was as high as 50 cells per vesicle. Staining with propidium iodide revealed that a significantly higher proportion of serovar Thompson cells remained viable when enclosed in vesicles than when free in solution. Enhanced survival rates were observed in vesicles that were secreted by both starved (F = 28.3, P < 0.001) and unstarved (F = 14.09, P < 0.005) Tetrahymena cells. Sequestration in vesicles also provided greater protection from low concentrations of calcium hypochlorite. Thus, the release of this human pathogen from Tetrahymena cells in high-density clusters enclosed in a membrane may have important implications for public health.

Coniochaeta ligniaria NRRL30616, an Ascomycete that metabolizes furfural and 5-hydroxymethylfurfural, is a unique strain that may be useful for detoxifying biomass sugars. NRRL30616 and 23 related fungal strains were screened for the ability to metabolize furans and grow in dilute-acid hydrolysate of corn stover. NRRL30616 was the best strain for removal of inhibitors from hydrolysate, and abatement of hydrolysate by inoculation with the strain allowed subsequent yeast fermentation of cellulose to ethanol.

Mannitol can be produced through fermentation by microorganisms. Currently, a few Lactobacillus strains are used to develop an efficient process for mannitol bioproduction; most of the strains produce mannitol from fructose with other products. An approach toward improving this process would be to genetically engineer Lactobacillus strains to increase fructose-to-mannitol conversion with decreased production of other products. We cloned the gene mtlK encoding mannitol-2-dehydrogenase (EC 1.1.1.67) that catalyzes the conversion of fructose into mannitol from Lactobacillus brevis using genomic polymerase chain reaction. The mtlK clone contains 1328 bp of DNA sequence including a 1002-bp open reading frame that consisted of 333 amino acids with a predicted molecular mass of about 36 kDa. The functional mannitol-2-dehydrogenase was produced by overexpressing mtlK via pRSETa vector in Escherichia coli BL21pLysS on isopropyl-beta-D-thiogalactopyranoside induction. The fusion protein is able to catalyze the reduction of fructose to mannitol at pH 5.35. Similar rates of catalytic reduction were observed using either the NADH or NADPH as cofactor under in vitro assay conditions. Genetically engineered Lactobacillus plantarum TF103 carrying the mtlK gene of L. brevis indicated increased mannitol production from glucose. The evaluation of mixed sugar fermentation and mannitol production by this strain is in progress. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Fermentat Biotechnol Res Unit, Peoria, IL 61604 USA.

Most yeasts, including industrial strains, are susceptible to these inhibitory compounds, especially when multiple inhibitors are present. Additional detoxification steps add cost and complexity to the process and generate additional waste products. To promote efficient bioethanol production, we studied the mechanisms of stress tolerance, particularly to fermentation inhibitors such as furfural and HMF. We recently reported a metabolite of 2,5-bis-hydroxymethylfuran as a conversion product of HMF and characterized a dose-dependent response of ethanologenic yeasts to inhibitors. In this study, we present newly adapted strains that demonstrated higher levels of tolerance to furfural and HMF. Saccharomyces cerevisiae 307-12H60 and 307-12HI20 and Pichia stipitis 307 10H60 showed enhanced biotransformation ability to reduce HMF to 2,5bis-hydroxymethylfuran at 30 and 60 mM, and S. cerevisiae 307-12-F40 converted furfural into furfuryl alcohol at significantly higher rates compared to the parental strains. Strains of S. cerevisiae converted 100% of HMF at 60 MM and S. cerevisiae 307-12-F40 converted 100% of furfural into furfuryl alcohol at 30 mM. The results of this study suggest a possible in situ detoxification of the inhibitors by using more inhibitor-tolerant yeast strains for bioethanol fermentation. The development of such tolerant strains provided a basis and useful materials for further studies on the mechanisms of stress tolerance. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Peoria, IL 61604 USA.

A 6-yr (1993 to 1998) field study was conducted at the Iowa State University's Northeastern Research Center near Nashua, Iowa, to evaluate the effects of non-traditional cropping systems (strip inter cropping (STR)-corn (Zea mays L.)/soybean (Glycine max L.)/oats (Avina saliva L.)); alfalfa rotation (ROT)-3-yr (1993 to 1995) alfalfa (Medicago sativa L.) followed by corn in 1996, soybean in 1997, and oats in 1998), and traditional cropping system (corn after soybean (CS) and soybean after corn (SC) on the flow weighted average nitrate-nitrogen (NO3-N) concentrations and NO3-N leaching losses with subsurface drainage water. The soils at the research site are loamy with 3% to 4% organic matter and are underlain by subsurface drainage system. The data collected from four experimental treatments were analyzed as an unbalanced incomplete block design using F-test and T-test among treatments and within treatments, respectively. When averaged across 6-yr, non-traditional cropping systems reduced flow weighted average NO3-N concentrations in subsurface drain water with highly significantly effect (P < 0.01) in comparison with traditional cropping system (6.5 vs. 11.2 mg L-(1)). Similarly, the strip inter cropping system increased corn grain yields by 5% (9.03 vs. 8.6 Mg ha-(1)) and reduced NO3-N leaching losses by 6% (12.6 vs. 13.5 kg-N ha-(1)) and showed no difference in soybean yields when compared with traditional cropping system. Results of the study indicate that strip inter cropping and alfalfa rotation systems have the potential to reduce NO3-N leaching into the shallow groundwater system and possibly can become one of the better sustainable farming systems in Midwestern agriculture.

Sediment-bonded pesticides and nutrients are washed from the field and sediment fills surface drainage channels (quarter-drains) within the field and increases the cost of maintaining the ditch system. A field experiment was conducted in the spring of 2002 to determine the effectiveness of Polyacrylamide (PAM) in reducing soil erosion from quarter-drains in fields planted to sugarcane. Eroded quarter-drain depth and soil loss per meter were measured after six rainfall events that occurred between 28 March and 1 July and produced a total cumulative rainfall of 368 mm. In March 2002 PAM was sprayed as an aqueous solution directly on newly installed quarter-drains at a rate of 18 kg ha-(1). The relative depth of erosion was measured after each storm event using plastic rulers, which were inserted into the bottom of quarter-drains using a custom made tool. When applied directly to the primary quarter-drains, PAM significantly reduced erosion depth by 76% compared with the no-PAM application. PAM was most effective for the first three storm events (cumulative rainfall depth of 161 mm) with an average 88% reduction in soil depth loss. Based on one year of study in St. Gabriel, Louisiana, PAM sprayed as an aqueous solution in a single application was effective in reducing soil erosion for the quarter-drain systems during the 4-month period after PAM application under normal Southern Louisiana weather condition. For soil with an average bulk density of 1500 kg m(-3) the average reduction in soil loss for PAM treated quarter-drain was 0.65 kg m(-1) of the primary quarter-drain for six events. At transition points between primary and secondary quarter-drains where PAM was not applied, a gradual deterioration of the side walls of the quarter-drain was visible. The original shape of semicircular quarter-drains was preserved through six consecutive storms events for plots treated with PAM. C1 USDA ARS, Natl Soil Dynam Lab, Auburn, AL USA.

It can be accomplished with flumes that back up flow in the furrow, which for moderate to steeply sloping fields causes only small changes in furrow water depth and thus has little influence on the water flow measurement. However, the ponding of water upstream from a flume can have a significant impact on the movement of sediment down the furrow. In one research study, measured sediment transport through the fume was reduced 40% over that measured in a furrow with only a non-constricting metal form that matched the furrow shape. A new furrow fume has been designed that overcomes the limitations of current v-shaped flumes or trapezoidal RBC flumes that cause significant backwater during furrow irrigation. This new fume has a trapezoidal shape with only a side contraction. It was designed to keep flow velocities high over the full range of flow conditions. This new flume is commercially available and has been working successfully in the field for three seasons. C1 USDA ARS, US Water Conservat Lab, Phoenix, AZ 85040 USA.

A GLM analyses of variance indicated NIT protein content increased significantly with increases in nitrogen rate and changes in method of nitrogen application. Protein ranged from 5.7% to 11.0% over all plots and treatments. The highest protein content occurred on plots receiving 202 kg N/ha; while the lowest occurred on plots receiving no nitrogen. Oil percentages did not vary significantly with nitrogen rate and they ranged from 2.2% to 4.3%. Starch content and extractable starch decreased significantly as nitrogen rate increased. Extractable starch ranged from 63.4% to 72.1%. The highest extractable starch level of 72.1% occurred on the plots with no nitrogen application; while the lowest extractable starch occurred on plots receiving 202 kg N/ha.

The proliferation of Triclosan (TCS) in consumer products has resulted in its presence in wastewater influent, effluent, and subsequently in streams. In this study, the two objectives were: 1) assess the utility of a passive-diffusion periphytometer in toxicity tests, and 2) evaluate the growth-inhibiting effects of TCS on periphytic algae at the White River, Northwest Arkansas. The periphytometer was deployed for one week with seven replicates of nine treatments, including control (deionized H2O), methanol, low TCS (50,mu g L-1), medium TCS (100 mu g L-1), high TCS (500 mu g L-1), nutrients (2000 mu g PO4-PL-1 and 20000 mu g NO3-NL-1), low TCS with nutrients, medium TCS with nutrients, and high TCS with nutrients. Relatively low stream nutrient concentrations were observed; maximum nitrate-nitrogen (NO3-N), total N, ammonium-nitrogen (NH4N-N), total organic carbon (TOC), and soluble reactive phosphorus (SRP) concentrations during the deployment were 230, 603, < 50, 12500, and 15 mu g L-1, respectively. The Student-Newman-Kuels test (alpha = 0.05) identified three significantly different groups within the treatments. The nutrients and low TCS with nutrients treatments had chlorophyll-a means of 10.9 and 5.8 mg m(-2), respectively, which were significantly different from each other and all other treatments. Chlorophyll-a content means of the remaining treatments ranged from 1.8 to 3.5 mg m(-2) and were not significantly different from each other. Exponential regression of chlorophyll-a contents in nutrient and TCS with nutrient treatments against TCS concentration produced a significant decreasing trend; however, no trend in chlorophyll-a content was observed in treatments without nutrients. The observed inhibition of periphytic algal growth in the treatments with additional NO3 and SRP suggests that the mechanism of TCS may be more complex than postulated. Periphytic response to TCS exposure was quantified using an innovative, in situ approach that warrants additional investigation. C1 Univ Florida, IFAS, Ctr Trop Res & Educ, Homestead, FL 33031 USA.

The dried residue was able to serve as an effective co-adhesive for phenol-formaldehyde (PF) bonding of aspen veneer sheets to one another. Testing of the resulting plywood panels revealed that the adhesive, formulated to contain 30% of its total dry weight as fermentation residue, displayed shear strength and wood failure values under both wet and dry conditions that were comparable with those of industry standards for PF that contained much smaller amounts of fillers or extenders. By contrast, PF adhesives prepared with 30% of dry weight as either unfermented lucerne fiber or conventional fillers or extenders rather than as fermentation residues, displayed poor performance, particularly under wet conditions.

We found that time-resolved imaging of apples artificially contaminated with feces allowed optimization of timing parameters for detection. Dairy feces were applied to Red Delicious and Golden Delicious apples. Laser-induced fluorescence responses were imaged by use of a gated intensified camera. We developed algorithms to automatically detect contamination iteratively by using one half of the apples and validated them by applying the optimized algorithms to the remaining apples. Results show that consideration of the timing of fluorescence responses to pulsed-laser excitation can enhance detection of feces on apples.

Channel catfish (initial mean weight = 0.77 kg) were stocked into six 0.04-ha ponds at similar to5775 kg ha(-1). Two ponds were assigned to each of three feeding regimes for a 4-week trial: fed daily to satiation, fed once weekly to satiation and not fed. Fish were measured for weight, processing yield and visceral components after 2 and 4 weeks, and for body shape after 4 weeks. Growth was fastest in fish fed daily, intermediate in fish fed weekly and slowest in unfed fish. There were no differences in survival among feeding regimes. After covariate adjustment for weight differences, fish fed daily had shorter, thicker bodies, and smaller heads than fish from feed-restricted treatments. Carcass yield was higher for females than males and higher at week 2 than at week 4, but was not affected by feeding regime. Fillet yield was higher for females than males, higher at week 2 than at week 4, and higher for fish fed daily than for feed-restricted fish (fed once weekly and not fed). Viscerosomatic index (VSI), visceral fat-somatic index (VFI) and hepatosomatic index were higher at week 2 than at week 4, and highest for fish fed daily, intermediate for fish fed weekly and lowest for unfed fish. Hepatosomatic index and VSI were higher for females than males, but VFI was not different between genders. The female gonadosomatic index increased over time but was not affected by feeding regime. Short-term feed restriction had negative impacts on growth and fillet yield. Processors could benefit by marketing severely feed-restricted channel catfish as carcasses rather than fillets since fillet yield declined but carcass yield was unchanged by feed restriction.

Antiserum raised against a purified 66-kDo group II esterase is specific for the denatured enzyme. This antiserum reacts similarly with both beetle homogenates from resistant and susceptible populations, although there is much higher signal intensity in immurroblots of resistant relative to susceptible beetles. These results suggest that overproduction of group II esterases is the underlying basis of esterase-mediated resistance in D. v. virgifera by demonstrating that (1) group II esterases are immunologically indistinguishable between the resistant and susceptible populations, and (2) the intensity differences are due to increased group II esterase proteins in the resistant population. The diagnostic potential of immunological-based assays was tested with a traditional diagnostic concentration bioassay and a biochemical-based native PAGE assay. Significant correlations were observed among all three diagnostic assays (regression coefficients ranging from 0.95 to 0.96). These results demonstrate the importance of the 66-kDa protein as a resistance-associated biochemical marker, thus emphasizing the potential for 66-kDa protein-targeted immunoossays in resistance monitoring programs.

Conventional disease control strategies rely heavily oil chemoprophylaxis, which is a tremendous cost to the industry. Existing vaccines consist of live virulent or attenuated Eimeria strains with limited scope of protection against an ever-evolving and widespread pathogen. The continual emergence of drug-resistant strains of Eimeria, coupled with the increasing regulations and bans oil the use of anticoccidial drugs ill commercial Poultry production, urges the need for novel approaches and alternative control strategies. Because of the complexity of the host immunity and the parasite life cycle, a comprehensive understanding of host-parasite interactions and protective immune mechanisms becomes necessary for successful prevention and control practices. Recent progress in functional genomics technology would facilitate the identification and characterization of host genes involved in immune responses as well as parasite genes and proteins that elicit protective lost responses. This study reviews recent coccidiosis research and provides information on host immunity, immunomodulation, and the latest advances in live and recombinant vaccine development against coccidiosis. Such information will help magnify our understanding of host-parasite biology and mucosal immunology, and we hope it will lead to comprehensive designs of nutritional interventions and vaccination strategies for coccidiosis.

Studies were conducted to observe how Escherichia coli cells would respond to subtherapeutic tetracycline concentrations under continuous culture (chemostat) conditions, to observe AI-2 activity within the probiotic chicken microbial consortium (Preempt (R) CF3; MS Bioscience, Dundee, IL) under in vitro conditions simulating a chicken cecum, and to observe the AI-2 activity in vivo within a chicken cecum as a function of exposure to subtherapeutic levels of chlortetracycline, tylosin, and vancomycin. The AI-2 activity in the E coli continuous culture showed a 20-fold increase over baseline conditions for up to 24 hours. When the E coli culture was subsequently exposed to pulses of chlortetracycline additions at subtherapeutic concentrations (2 mu g/ml), AI-2 activity increased with increasing levels of tetracycline additions. The probiotic Preempt CF3 culture, however, did not exhibit any AI-2 activity in Viande Levure (VL) medium in the presence or absence of subtherapeutic levels of tetracycline. In vivo studies in the cecum of poultry chicks demonstrate that though AI-2 activity increased initially in the presence of vancomycin, there was no significant increase in AI-2 activity in the presence of tetracycline or tylosin. These results indicate that detectable levels of AI-2 activity are not evident within the probiotic culture (CF3) or within the chicken cecum. Understanding the relationships between AI-2 activity and microbial consortia characteristics could provide clues regarding the vulnerability of poultry chicks to enteric bacterial pathogen colonization.

The LPAI viruses caused localized virus infections in respiratory and gastrointestinal (GI) tracts. Virus was not detected in blood, bone marrow, or breast and thigh meat, and feeding breast and thigh meat from virus-infected birds did not transmit the virus. In contrast to the two LPAI viruses, A/chicken/Pennsylvania/1370/1983 (H5N2) HPAI virus caused respiratory and GI tract infections with systemic spread, and virus was detected in blood, bone marrow, and breast and thigh meat. Feeding breast or thigh meat from HPAI (H5N2) virus-infected chickens to other chickens did not transmit the infection. However, A/chicken/Korea/ES/2003 (H5N1) HPAI virus produced high titers of virus in the breast meat, and feeding breast meat from these infected chickens to other chickens resulted in Al virus infection and death. Usage of either recombinant fowlpox vaccine with H5 Al gene insert or inactivated Al whole-virus vaccines prevented HPAI virus in breast meat. These data indicate that the potential for LPAI virus appearing in meat of infected chickens is negligible, while the potential for having HPAI virus in meat from infected chickens is high, but proper usage of vaccines call prevent HPAI virus from being present in meat.

Although PEC is considered to be a polymicrobial disease, numerous viruses, including turkey coronavirus (TCV), turkey astrovirus type 2 (TAstV-2), and avian reoviruses (ARVs), have been associated with PEC-like disease. Real-time reverse rranscription-polymerase chain reaction (RRT-PCR), a highly sensitive and specific detection method for viral RNA, was developed in a multiplex format for the simultaneous detection of TAstV-2 and TCV and for the detection of two genetic types of ARV. Assay sensitivity was determined using in vitro transcribed RNA and varied by target between 150 gene copies for TAstV-2 alone and 2200 gene copies for TCV when multiplexed. Virus detection was evaluated with samples collected from poults inoculated at I day of age with each of the viruses. Cloacal swabs and intestinal samples were obtained at 1, 2, 3, 4, 6, 9, 14, 17, and 21 days after inoculation, processed, and tested for virus detection by RRT-PCR. Cloacal swabs from TAstV-2- and TCV-infected poults were shown to have sensitivity for virus detection similar to that of intestinal samples when compared directly. ARV detection by RRT-PCR was compared with virus isolation and had similar sensitivity. C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA. Univ Georgia, Dept Avian Med, Athens, GA 30602 USA.

Vaccination efficacy was assessed by increased serum anti-3-1E antibody titers, reduced fecal oocyst shedding, and enhanced body weight gain following experimental infection with E. acervulina. When used alone, anti-3-1E antibody titers were transiently, but reproducibly, increased at 2 wk and 3 wk posthatching in a dose-dependent manner. Similarly, significantly reduced oocyst shedding and increased weight gain were observed at relatively high-dose 3-1E vaccinations (>= 25 mu g/egg). Combined immunization with the 3-1E and IL-1, IL-2, IL-15, or IFN-gamma genes induced higher serum antibody responses compared with immunization with 3-1E alone. Following parasite infection, chickens hatched from embryos given the 3-1E gene plus the IL-2 or IL-15 genes displayed significantly reduced oocyst shedding compared with those given 3-1E alone, while 3-1E plus IL-15 or IFN-gamma significantly increased weight gain compared with administration of 3-1E alone. Taken together, these results indicate that in ovo immunization with a recombinant Eimeria gene in conjunction with cytokine adjuvants stimulates protective intestinal immunity against coccidiosis.

Attempts to improve the vaccination process include numerous variations of individual shop-built vaccinators in use by the layer sector of the poultry industry. Each of these vaccinators has limitations that contribute to poor vaccinations. Major problems include the nonuniform speed of the applicator system and pressure fluctuations at the spray nozzles, which contribute to sporadic dispersion of the vaccine as the vaccinator is pushed or carried past the cages. A battery-powered, self-propelled, constant-speed vaccinator was designed and constructed that operates with constant nozzle pressure. In field use, this vaccinator has resulted in both labor savings (reduction of manpower from five to one to vaccinate 75,000 chickens) and time savings (from 45 min to 7.5 min/poultry house) as well as improved vaccination results (higher positive seroconversion rates) against the poultry pathogen Mycoplasma gallisepticum (MG), a bacterium associated with losses of 15.7 eggs/hen over a 45-wk laying Period in MG-infected layers as compared with layers maintained free from infection with MG.

At 1 hr, 1 day, and 1 wk after inoculation, broilers (n = 5) from the orally and intracloacally inoculated groups along with control birds (n = 4) were humanely killed by cervical dislocation. The broilers from the control and treatment groups were aseptically opened, and the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca were aseptically removed and individually analyzed for C jejuni. Overall, C jejuni was isolated after oral inoculation from 13% (10/75) 17% (13/75), and 28% (14/50) of the 1-hr, 1-day, and 1-wk samples, respectively. Campylobacter jejuni was isolated from 10% (4/40), 8% (3/40), 10% (4/40), 25% (10/40), and 40% (16/40) of the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca samples, respectively. Following the intracloacal route of inoculation, C. jejuni was recovered from 32% (24/75), 8% (6/75), and 16% (8/50) of the 1-hr, 1-day, and 1-wk samples, respectively. Campylobacter jejuni was isolated from 5% (2/40), 5% (2/40), 5% (2/40), 45% (18/40), and 40% (16/40) of the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca samples, respectively, for all sampling periods. Campylobacter spp. were not recovered from sample sites examined from the control broilers from trial one, trial two, or trial three samples examined after 1 hr and 1 day. However, one control sample was positive from the 1-wk sampling from repetition three; therefore, those data were omitted. The rapid movement of Campylobacter to internal organs following both oral and intracloacal inoculation may be significant, particularly if it persists in these organs as reservoirs throughout the 65-wk life cycle of breeding birds.

The isolated enzyme had molecular mass of 25.5 kD and pI 7.4. The enzyme was also characterized by temperature optimum at 55 degrees C, pH optimum at 8.5, and K value of 0.04 mM (for hydrolysis of Bz-Arg-pNA). According to inhibitor analysis the enzyme is a trypsin-like serine proteinase stable within the pH range of 5.0-9.5. The enzyme hydrolyzes peptide bonds formed by Arg or Lys residues in the PI position with a preference for relatively long peptide substrates. The N-terminal amino acid sequence, IVGGSSI-SISSVPXQIXLQY, shares 50-72% identity with other insect trypsin-like proteinases, and 44-50% identity to mammalian trypsins. The isolated enzyme is sensitive to inhibition by plant proteinase inhibitors and it can serve as a suitable target for control of digestion in this stored product pest.

We developed it to provide background and context for this special issue on soil respiration and to synthesize the presentations and discussions at the workshop. Soil respiration is the largest component of ecosystem respiration. Because autotrophic and heterotrophic activity belowground is controlled by substrate availability, soil respiration is strongly linked to plant metabolism, photosynthesis and litterfall. This link dominates both base rates and short-term fluctuations in soil respiration and suggests many roles for soil respiration as an indicator of ecosystem metabolism. However, the strong links between above and belowground processes complicate using soil respiration to understand changes in ecosystem carbon storage. Root and associated mycorrhizal respiration produce roughly half of soil respiration, with much of the remainder derived from decomposition of recently produced root and leaf litter. Changes in the carbon stored in the soil generally contribute little to soil respiration, but these changes, together with shifts in plant carbon allocation, determine ecosystem carbon storage belowground and its exchange with the atmosphere. Identifying the small signal from changes in large, slow carbon pools in flux dominated by decomposition of recent material and autotrophic and mycorrhizal respiration is a significant challenge. A mechanistic understanding of the belowground carbon cycle and of the response of different components to the environment will aid in identifying this signal. Our workshop identified information needs to help build that understanding: (1) the mechanisms that control the coupling of canopy and belowground processes; (2) the responses of root and heterotrophic respiration to environment; (3) plant carbon allocation patterns, particularly in different forest developmental stages, and in response to treatments (warming, CO2, nitrogen additions); and (4) coupling measurements of soil respiration with aboveground processes and changes in soil carbon. Multi-factor experiments need to be sufficiently long to allow the systems to adjust to the treatments. New technologies will be necessary to reduce uncertainty in estimates of carbon allocation, soil carbon pool sizes, and different responses of roots and microbes to environmental conditions.

Gas flux data from rangeland soils that included a large number of measurements at low temperatures were used to model soil CO2 emissions as a function of soil temperature and water content. Our arctangent temperature function predicts that Q(10) values vary inversely with temperature and that CO2 fluxes are significant below 0 degrees C. Independent data representing a broad range of ecosystems and temperature values were used for model testing. The effects of plant phenology, differences in substrate availability among sites, and water limitation were accounted for so that the temperature equations could be fairly evaluated. Four of the six tested models did equally well at simulating the observed soil CO2 respiration rates. However, the arctangent variable Q(10) model agreed closely with observed Q(10) values over a wide range of temperatures (r(2)=0.94) and was superior to published variable Q(10) equations using the Akaike information criterion (AIC). The arctangent temperature equation explained 16-85% of the observed intra-site variability in CO2 flux rates. Including a water stress factor yielded a stronger correlation than temperature alone only in the dryland soils. The observed change in Q(10) with increasing temperature was the same for data sets that included only heterotrophic respiration and data sets that included both heterotrophic and autotrophic respiration.

Although considerable research has focused on quantifying this flux during the growing season, comparatively little effort has focused on non-growing season fluxes. We measured soil CO(2) efflux through snow in 50 and similar to 300 year old subalpine forest stands near Fraser CO. Our objectives were to quantify seasonal patterns in wintertime soil CO(2) flux; determine if differences in soil CO(2) flux between the two forest ages during the growing season persist during winter; and to quantify the sample size necessary to discern treatment differences. Soil CO(2) flux during the 2002 - 2003 and 2003 - 2004 snow season averaged 0.31 and 0.35 mu mols m(-2) s(-1) for the young and old forests respectively; similar to the relative difference observed during summer. There was a significant seasonal pattern of soil CO(2) flux during the winter with fluxes averaging 0.22 mu mols m(-2) s(-1) in December and January and increasing to an average of 0.61 mu mols m(-2) s(-1) in May. Within-plot variability for measurements used in calculating flux was low. The coefficients of variation ( CV) for CO(2) concentration, snowpack density, and snow depth were 17, 8 and 14%, respectively, yielding a CV for flux measurements within-plot of 29%. A within plot CV of 29% requires 8 sub-samples per plot to estimate the mean flux with a standard error of +/- 10% of the mean. Variability in CO(2) flux estimates among plots ( size = 400 m(2)) was similar to that within plot and was also low ( CV = similar to 28%). With a CV of 28% among plots, ten plots per treatment would have a 50% probability of detecting a 25% difference in treatment means for alpha = 0.05.

The effect of stand age on F-s was examined using a replicated chronosequence approach in which stands ranging from 1 to 25 years since planting were investigated. Soil CO2 efflux was measured on both VA and SC sites for over a year using a closed dynamic system. Multiple linear regression was used to evaluate F-s correlates and examine the relationship between candidate explanatory variables and F-s. Soil temperature ( top 10 cm) was the major correlate with F-s on both locations. We observed a positive age effect on F-s in VA stands and no relationship between age and F-s in SC stands. Annual soil C efflux declined with stand age in SC due to both reductions in soil temperatures as crown closure occurs and a diminishing heterotrophic C substrate pool. Annual estimated efflux ranges from 16.7 to 13.2 Mg C ha(-1) for 1 and 20-year-old stands, respectively. In contrast, annual soil C efflux increased with age in VA stands as a result of the positive relationship between stand age and F-s, which appears to be related to an increase in the contribution of root respiration to total F-s over time. In VA stands, efflux estimates range from 7.6 to 12.3 Mg C ha(-1) for 1 and 20-year-old stands, respectively. These results demonstrate the need to further consider the impact forest management and within-region variability have on soil C efflux over time when estimating C budgets.

Combining data from multiple researchers for larger-scale modeling and assessment will only be valid if their methodologies provide directly comparable results. We conducted a series of laboratory and field tests to assess the presence and magnitude of soil CO2 efflux measurement system x environment interactions. Laboratory comparisons were made with a dynamic, steady-state CO2 flux generation apparatus, wherein gas diffusion drove flux without creating pressure differentials through three artificial soil media of varying air-filled porosity. Under these conditions, two closed systems (Li-6400-09 and SRC-1) exhibited errors that were dependent on physical properties of the artificial media. The open system (ACES) underestimated CO2 flux. However, unlike the two other systems, the ACES results could be corrected with a single calibration equation that was unaffected by physical differences in artificial media. Both scale and rank changes occurred among the measurement systems across four sites. Our work clearly shows that soil CO2 efflux measurement system x environment interactions do occur and can substantially impact estimates of soil CO2 efflux. Until reliable calibration techniques are developed and applied, such interactions make direct comparison of published rates, and C budgets estimated using such rates, difficult.

The algorithm utilizes Cap3 to perform an initial clustering of related EST sequences to produce a consensus sequence of a gene family. These consensus sequences are then used to collect all ESTs in the original EST library that are related using BLAST. A redundancy based criterion is applied to each EST to identify reliable unique gene-sequences. Using a highly inbred genome as a source of ESTs eliminates the necessity of computing covariance on each polymorphism to identify alleles of the same gene, thus making this algorithm more streamlined than other alternatives which must computationally attempt to distinguish genes from alleles.

These tests were supplemental to an earlier extensive host-range study that established P. carduorum from musk thistle as host specific, useful for biological control, and suitable for limited field tests in Virginia. Test plants in the current study were evaluated in support of a proposal to use the rust in the western United States, and particularly, in California. None of the test plants in this study had been evaluated in previous assessments and all were either rare, endangered or threatened in California. Tests were conducted in both field and greenhouse settings. Field tests were run for two seasons, and test plants were inoculated by natural spread of the pathogen from source plants inside rings of test plants. Greenhouse tests involved direct inoculation under optimal conditions of dew and temperature (18-20 degreesC, 16 h) for infection. None of the seven Cirsium species or subspecies tested became infected by P. carduorum, either in field or greenhouse tests, compared to infection of 98% of the individual musk thistle plants (n = 102) from all the studies. Modern artichoke cultivars were tested only by direct inoculation under optimal greenhouse conditions. All artichoke plants (n = 115) either were immune (no macroscopic symptoms, n = 69) or at most, resistant (n = 46); pustules on all but two of the resistant plants were very small ( less than or equal to 0.30 mm diam). Despite infections on artichokes, P. carduorum could not be maintained on artichokes under optimal greenhouse conditions. These results confirm earlier findings from host-range tests and risk assessments of P. carduorum. This information suggests that rare, threatened, or endangered Cirsium spp. and modern artichoke cultivars are not likely to be adversely affected by the use of P. carduorum for biological control of musk thistle. These data have been reviewed by grower groups and regulatory agencies in a proposal for permission to use the rust for musk thistle control throughout the United States. Published by Elsevier Inc.

Although the bacterium is known to affect several plant species in the Asteraceae and has been reported in several countries, little is known of its genetic diversity. The genetic relatedness of 24 strains of P. syringae pv. tagetis with respect to each other and to other P. syringae and Pseudomonas savastanoi pathovars was examined using 16S-23S rDNA intergenic spacer (ITS) sequence analysis. The size of the 16S-23S rDNA ITS regions ranged from 508 to 548 bp in length for all 17 P. syringae and P. savastanoi pathovars examined. The size of the 16S-23S rDNA ITS regions for all the P. syringae pv. helianthi and all the P. syringae pv. tagetis strains examined were 526 bp in length. Furthermore, the 16S-23S rDNA ITS regions of both P. syringae pv. tagetis and P. syringae pv. helianthi had DNA signatures at specific nucleotides that distinguished them from the 15 other P. svringae and P. savastanoi pathovars examined. These results provide strong evidence that P. syringae pv. helianthi is a nontoxigenic form of P. syringae pv. tagetis. The results also demonstrated that there is little genetic diversity among the known strains of P. syringae pv. tagetis. The genetic differences that do exist were not correlated with differences in host plant, geographical origin, or the ability to produce toxin. Published by Elsevier Inc.

In vitro exposure to M. albus volatile compounds for 3 days killed Penicillium digitatum and Geotrichum citri-aurantii, causes of green mold and sour rot of lemons, respectively. Lemons were wound-inoculated with P. digitatum and placed in closed 11-L plastic boxes with rye grain cultures of M. albus at ambient temperature. There was no contact between the fungus and the fruit. Biofumigation for 24-72 h controlled green mold significantly, even when treatment began 24 h after inoculation. Effectiveness was related to the amount of M. albus present. In tests conducted inside a 11.7-m(3) degreening room with 5 ppm ethylene at 20 degreesC, green mold incidence on lemons was reduced on average from 89.8 to 26.2% after exposure to M. albus for 48 h. Ethylene accelerates color development in harvested citrus fruit. M. albus had no effect on color development. Biofumigation in small boxes immediately after inoculation controlled sour rot, but was ineffective if applied 24 h later. G. citri-aurantii may be less sensitive to the volatile compounds than P. digitatum or escapes exposure within the fruit rind. Biofumigation with M. albus could control decay effectively in storage rooms or shipping packages. (C) 2004 Elsevier Inc. All rights reserved. C1 AgraQuest Inc, Davis, CA 95616 USA.

Supplementation of the diet of T. ni larvae with 10-20 ppm Se resulted in a I day delay in pupation. The effects of the addition and/or removal of dietary Se on total Se bioaccumulation and sequestration were determined by neutron activation analysis of pupae. Early penultimate instar larvae moved from selenium containing diet to basal diet lost total pupal Se content down to the level of those fed basal diet. Conversely, larvae moved from basal diet to diet containing additional Se rapidly attained pupal Se levels comparable to larvae fed Se throughout larval development. Then fore, dietary Se is rapidly accumulated or lost during larval development, but significant amounts are sequestered from diet into pupae. Larvae were reared on diet supplemented with 5 or 10 ppm Se until the onset of the penultimate instar then infected per os with increasing concentrations of the fatal baculovirus Autographa californica multiple nucleopolyhedrovirus (AcMNPV). Larvae fed Se in the penultimate and ultimate instars were more resistant to viral infection than larvae not fed Se in the final instars. This study indicates that dietary Se levels rapidly impact Se assimilation and sequestration and that tissue Se levels are an important factor in resistance to AcMNPV infection in larval T ni.

This invader was first discovered in San Francisco Bay almost a decade earlier and by 1995 it had spread to northern California. The coast-wide colonization event we studied in 1998 (El Nino cohort) was correlated with unusually strong north flowing coastal currents from September 1997 to April 1998. Larval transport by ocean currents from established populations to the south appeared to be the mechanism for the colonization. Crabs from the 1998-year class grew faster than counterparts from Maine and Europe, averaging 14 mm in carapace width in June, and 46 mm by September 1998. By the end of their second summer, males ranged from 52 to 80 mm in carapace width, and by fall of 2000 some males attained a carapace width of over 90 mm. The life span for C. maenasit in Oregon, Washington and British Columbia is estimated to be similar as in Europe and Maine: 4-6 years. Even though the initial colonists (98-year class) are dying of senescence, and coastal currents have not been favorable for larval transport from source populations in California, green crabs do persist in Oregon and Washington estuaries. It appears that local reproduction and recruitment in some years is high enough to keep this population from going extinct. C1 Oregon State Univ, Dept Zool, Corvallis, OR 97331 USA.

Quantifying the influx of nonindigenous plant pest species through foreign trade is required for national and international risk assessments, monitoring and conservation efforts, and evaluation of ecological factors that affect invasion success. Here we use statistically robust data collected at US ports of entry and border crossings to estimate arrival rates of nonindigenous insect species via four cargo pathways and to evaluate the effectiveness of current efforts to monitor arrival of nonindigenous insect species. Interception rates were highest in refrigerated maritime cargo where a new insect species was intercepted on average every 54 inspections. Projected estimates of insect species richness stabilized only for non-refrigerated maritime cargo and US-Mexico border cargo, where inspectors likely detected 19-2% and 30-50% of the species being transported through these respective pathways. Conservative estimates of establishment suggest that 42 insect species may have become established through these four pathways between 1997 and 2001.

These methods provide powerful means for general screening of organisms actively producing and accumulating PHAs. The Southern blot hybridization method additionally allows the identification of potential PHA-producing microorganisms. Polymerase chain reaction (PCR)-based detection methods further afford rapid and sensitive means to screen for PHA biosynthesis genes. Specific PCR assays had been developed for the simultaneous or individual detection of the class 11 mcl-PHA synthase genes of Pseudomonas. The amplicons (similar to 0.54 kb) can be directly sequenced or used as probes for hybridization studies. The sequence information can further be used to initiate chromosome walking for an eventual cloning of the complete PHA biosynthesis operon. In addition, the amplification pattern and sequence data can be used to differentiate subgroups of organisms, as demonstrated for P. corrugata and P. mediterranea. Other researchers reported PCR methods for the detection of scl-PHA synthase genes and those of Bacillus spp., thus greatly expanding the types of PHA synthase gene and the organisms that can be characterized by this approach. The vast sequence information obtainable through PCR-based studies of various PHA synthase operons should facilitate the identification or construction of new PHA synthases capable of synthesizing novel PHAs.

The objective of this study was to evaluate the fertilizer value of dried algal biomass that had been grown using anaerobically digested dairy manure. Results from a flask study using two soils amended with algal biomass showed that 3% of total algal nitrogen (N) was present as plant available N at day 0. Approximately 33% of algal N was converted to plant available N within 21 days at 25 degreesC in both soils. Levels of Mehlich-3 extractable phosphorus (P) in the two soils rose with increasing levels of algal amendment but were also influenced by existing soil P levels. Results from plant growth experiments showed that 20-day old cucumber and corn seedlings grown in algae-amended potting mix contained 15-20% of applied N, 46-60% of available N, and 38-60% of the applied P. Seedlings grown in algae-amended potting mixes were equivalent to those grown with comparable levels of fertilizer amended potting mixes with respect to seedling dry weight and nutrient content. These results suggest that dried algal biomass produced from treatment of anaerobically digested dairy manure can substitute for commercial fertilizers used for potting systems.

This process is often artificially induced in commercial settings in order to extend the productive life of a flock of hens. The most common method for the induction of molt is feed withdrawal for a period of several days. It has been noted that feed withdrawal, while effective in inducing molt and allowing an adequate reproductive rest period for the hen, may cause deleterious effects on the animal. This has prompted the investigation of alternatives to feed deprivation for the induction of molt in commercial laying hens. This study involved feeding alfalfa to hens to assess its ability to induce molt. Results show that alfalfa meal and alfalfa pelleted diets were equally effective as feed withdrawal in causing ovary weight regression in birds. Molted hens induced by alfalfa diets exhibited postmolt levels of egg production over a twelve week period that were similar to that of hens molted by feed withdrawal. The postmolt eggs laid by hens molted by alfalfa were of comparable quality to eggs from feed deprived hens. Alfalfa, a fibrous feed with low metabolizable energy, may be provided to hens on an ad libitum basis for an effective molt induction that retains comparable egg quality and production.

Accordingly, recombinant single chain variable fragment ( ScFv) antibody was constructed by amplification of the VH and VL genes from chicken hybridoma, 8C3 and when expressed in E. coli gave 5 mg l(-1). The expressed protein showed antigen binding activity equivalent to that of the parental mAb. In addition, nucleotide sequence comparison of 8C3 gene to the germline chicken VL genes suggested that the gene conversion with Vk pseudogenes might contribute to the diversi. cation of VL genes in chickens.

Fusions of the F, HN and HN2 (duplicated HN epitope) were made in the internal beta H-beta I loop (motif 5) within the CMV CP. Recombinant RNA3 transcripts of the Ixora strain of CMV were inoculated on to Nicotiana benthamiana, together with CMV RNA1 and CMV RNA2. When the F and HN epitopes were placed in the internal motif, the modified virus was infectious and the HN NDV epitope was recognized by anti-NDV sera. However, in some plants, deletions of one to several of the inserted amino acids occurred. A duplication of the HN epitope rendered the virus non-viable.

The initial habitat-scale densities of trout were positively related to both depth and cover, although by the end of the experiment, the influence of cover on density was less apparent. Survival varied substantially, but with no clear relationship to any of the physical factors that we measured. Mean growth was density dependent, positively influenced by habitat depth, and also increased downstream within the 2-km study reach. The overall change in trout biomass over the experiment was also negatively related to fish density and positively influenced by habitat depth. Individual growth within habitats appeared to be unrelated to body size. The positive influences of water depth and distance downstream on trout growth in this experiment suggest that management actions that increase dry season discharge and limit aggradation will benefit salmonids in small streams.

Franco) for Swiss needle cast ( SNC; caused by Phaeocryptopus gaeumannii ( Rohde) Petrak) tolerance was investigated using 55 Douglas- fir families from western Oregon. Seedlings were inoculated with P. gaeumannii naturally in the field and were visually scored for a variety of SNC symptom traits ( i.e., needle and foliage color, and retention) at the seedling stage ( age 2) and in " mature" ( ages 10 and 12) trees at two test sites for both the seedling and mature ages. Seedlings were also assessed in the laboratory for SNC symptom traits, for proportion of needle stomata occluded with pseudothecia ( PSOP), and for amount of P. gaeumannii DNA in needles. Although families differed significantly at both ages for all SNC symptom traits and for PSOP, they did not differ for amount of fungal DNA. Thus, genetic variation in SNC symptoms appears to be primarily due to differences in tolerance to the disease rather than to resistance to infection per se. Estimated individual- tree heritabilities for SNC symptom traits were low to moderate ( mean h(i)(2) = 0.19, range 0.06 - 0.37) at both ages, and within each age- class these traits were moderately to strongly genetically correlated ( mean r(A) = 0.69, range 0.42 - 0.95). Type B genetic correlations between SNC symptom traits in seedlings and mature trees ranged from 0 to 0.83 and were weakest for traits measured in the laboratory. Genetic gain estimates indicated that family selection for SNC tolerance ( i.e., greener needles or greater foliage retention) at the seedling stage can be very effective in increasing tolerance in older trees.

Presented here is a comprehensive research effort to evaluate six indirect sampling techniques for estimating CBD. As reference data, detailed crown fuel biomass measurements were taken on each tree within fixed-area plots located in five important conifers types in the western United States, using destructive sampling following a series of four sampling stages to measure the vertical and horizontal distribution of canopy biomass. The six ground-based indirect measurement techniques used these instruments: LI- COR LAI- 2000, AccuPAR ceptometer, CID digital plant canopy imager, hemispherical photography, spherical densiometer, and point sampling. These techniques were compared with four aggregations of crown biomass to compute CBD: foliage only, foliage and small branchwood, foliage and all branchwood ( no stems), and all canopy biomass components. Most techniques had the best performance when all canopy biomass components except stems were used. Performance dropped only slightly when the foliage and small branchwood canopy biomass aggregation ( best approximates fuels available for crown fires) was employed. The LAI- 2000, hemispherical photography, and CID plant canopy imager performed best. Regression equations that predict CBD from gap fraction are presented for all six techniques.

To facilitate development of conservation strategies, we used DNA sequences and RAPDs (random amplified polymorphic DNA) to examine differences among populations of this species. Phylogenetic analyses of cytochrome b revealed a clade of haplotypes from populations north of the Columbia River derived from a clade containing haplotypes from the river's southwestern region. Haplotypes from southeastern populations formed a separate clade. Nucleotide diversity was reduced in northern populations relative to southern populations. These results were corroborated by analyses of RAPD loci, which revealed similar patterns of clustering and diversity. Network analyses suggested that northern populations were colonized following a range expansion mediated by individuals from populations located southwest of the river. Changes in the Columbia River's location during the Pliocene and Pleistocene likely released distributional constraints on this species, permitting their northern range expansion. Based on the barrier presented by the Columbia River's present location and differences in haplotype diversity and population structure observed between northern and southern populations, we suggest that designation of separate management units encompassing each region may assist with mitigating different threats to this species.

Treatments aimed at reducing levels of circulating LDL are regarded, therefore, as cardioprotective. The cholesterol lowering properties of plant sterols have been known for some time and many clinical studies have confirmed the efficacy of sitosterol in lowering plasma LDL-C concentrations. Animal studies have also shown reductions in LDL by sitosterol. The use of animal models has been useful in facilitating the elucidation of specific mechanisms by which this sterol exerts its hypocholesterolemic action. It is well known that plant sterols compete with cholesterol for space within bile salt micelles in the intestinal lumen thereby reducing cholesterol absorption. The understanding of the function of plant sterols in impeding cholesterol absorption has been clarified with the discovery of the adenosine binding cassette transporters, ABCG5/8, involved in the regulation of sterol absorption and secretion into the enterocyte and hepatocyte. Compared to cholesterol and other sterols, sitosterol is preferentially pumped out to the intestinal lumen by the ABCG5/8 transporters. This selective binding of sitosterol to the transporters ultimately results in significant lowering of plasma cholesterol. However, some findings support the hypothesis that plant sterols might be an additional risk factor for coronary heart disease. From the review of these studies, it is apparent that sitosterol is a useful dietary supplement for the lowering of plasma cholesterol. Nevertheless, this plant sterol should be used with caution in certain individuals who have a higher absorption rate of sitosterol. C1 Univ Connecticut, Dept Nutr Sci, Storrs, CT 06269 USA.

The physical and rheological properties of cakes containing shortening replaced with 20, 40, and 60% by weight of Oatrim were characterized. The increase in the specific gravity of the cakes and the decrease in the viscosity as more shortening was replaced with Oatrim were correlated with the change in the cake volume. The number of air bubbles present in the cake batters varied significantly; however, the size of the observed bubbles did not change. The cakes containing more Oatrim displayed a higher starch gelatinization temperature due to the amylodextrins in the Oatrim. The dynamic rheological properties of the cakes were investigated during baking and correlated with the differential scanning calorimetry results. The oscillatory shear storage moduli decreased upon initial heating. then increased due to starch gelatinization, and finally reached a plateau value that varied based on the sample composition. Moreover, increased replacement of shortening with Oatrim resulted in higher observed oscillatory shear storage moduli. The cakes prepared with up to 20% by weight of Oatrim did not evidence significant changes in softness (P < 0.01) and generally exhibited similar physical properties to the control cake.

Barley was used as the standard of comparison because its endoproteinase complement has been studied previously in the greatest detail. The characteristics of the grain proteases were appraised from their migration patterns and by how they were affected by pH levels. All of the germinated grains contained multiple enzyme activities and their separation patterns and pH levels were at least similar to those of barley. The proteinases of the bread and durum wheats, rye, oat, and sorghum were most similar to those of barley, whereas the other grains provided more varied patterns. The rice and buckwheat proteinases developed much more slowly than those of the other grains. The activity patterns of the triticale resembled those of the parents, wheat and rye, but the triticale contained many more activities and higher overall proteolytic activities than any of the other species. These results should be applied to scientific or commercial procedures with caution because grains contain potent endogenous proteinase inhibitors that could inactivate some of these enzymes in various tissues or germination stages.

The starch fraction was separated further into large and small granules by repeated sedimentation. Large (10-40 mu m diameter) and small (1-15 mu m diameter) starch fractions were examined. Flour fractions were reconstituted to original levels in the flour using composites of varying weight percentages of starch granules: 0% small granules (100% large granules), 30, 60, and 100% (0% large granules). A modified straight-dough method was used in an experimental baking test. Crumb grain and texture were significantly affected. The bread made from the reconstituted flour with 30% small granules and 70% large granules starch had the highest crumb grain score (4.0, subjective method), the highest peak fineness value (1,029), and the second-highest elongation ratio (1.55). Inferior crumb grain scores and low fineness and elongation ratios were observed in breads made from flours with starch fractions with 100% small granules or 100% large granules. As the proportion of small granules increased in the reconstituted flour, it yielded bread with softer texture that was better maintained than the bread made from the reconstituted reference flour during storage.

Additionally, alcohol and tobacco use are associated with an increased risk for colon cancer, but the early pathologic events by which these agents promote neoplastic transformation are not well understood. Aberrant crypt foci (ACF) are potential precursors of adenoma and cancer, and can be visualized by magnification endoscopy. We hypothesized that folate depletion is linked to ACF formation and therefore studied the association between tissue folate, dietary habits, and ACF number in patients undergoing screening colonoscopy. Methods: Eighty-three patients, undergoing screening colonoscopy at an urban Veterans Affairs and university hospital, completed a questionnaire concerning alcohol, nonsteroidal anti-inflammatory drug (NSAID), and tobacco use. Folate intake was calculated from food frequency questionnaires. Rectal ACFs were scored using magnification chromoendoscopy (magnification, 35X) by methylene blue staining. Folate concentrations in rectal biopsy specimens were determined by microtiter bioassay. Results: ACF number increased with age and with increasing tobacco intake. Decreased colonic folate level was associated with increased homocysteine levels and lower dietary folate intake but did not correlate with ACF number. Conclusions: Increasing age and tobacco use were linked independently to the presence of colonic ACF in this predominantly African-American population. Folate, alcohol, and acetylsalicylic acid (ASA) use did not influence the prevalence of these lesions. C1 Univ Illinois, Dept Med, Chicago, IL 60612 USA.

Keratin fibers are mixed into high-density polyethylene (HDPE) at 20 wt% using a Brabender mixing head. This is the compounding step and the variables studied are compounding time, temperature, speed and state of fiber dispersion. Following compounding, the composites are compression molded at various times and temperatures and this is the molding step. The effects of compounding and molding are studied using tensile testing and scanning electron microscopy. It is found that keratin feather fiber provides a stiffness increase to HDPE but lowers tensile breaking stress. The fibers are thermally stable for long periods of time up to 200 degreesC, but the best composite properties are found at processing temperatures of 205 degreesC, where the fibers are only stable for a few minutes.

Food waste, generated from a residence dining hall, was fermented with and without a microbial inoculant for 20 days. The resulting soil conditioners were incorporated into soil (Mexico silt loam) by tilling to a 15-cm depth using a rotary tiller. Melon seedlings were transplanted three weeks after soil amendment. Soil nutrient levels and microbial activity were monitored periodically during the growing season to detect effects of the soil conditioners on soils and plant growth. Fruit weight per plant was significantly (P <= 0.05) increased with the microbially-inoculated soil conditioner compared to the control in both years, but was not different from the non-inoculated soil conditioner in 2000 or the fertilizer treatment in 2001. Soil conditioners produced from food wastes inoculated with selected microorganisms were as effective as a fertilizer in promoting soil microbial activity and melon growth. Long-term studies (> 2 yr) are needed to verify that enhancement of microbial activity and plant growth is due exclusively to EM-based soil conditioners.

In this study, we evaluated the suitability of two locally available composts as media for lettuce and tatsoi produced organically in an unheated greenhouse. One of the composts was produced from food residuals with landscape wastes as a bulking agent, while the other was generated from used horse bedding. Although the two materials had relatively similar total N contents, C:N ratios, and bulk densities, they performed very differently as potting media. Net N mineralization, measured in laboratory incubations, was high in the compost derived from food residuals, but the horse-bedding compost showed net N immobilization, perhaps due to high salinity. Crop production in the food residuals compost was statistically similar to a control treatment consisting of a commercial peat-based potting medium with synthetic fertilizer. Crop growth in the medium consisting of horse-bedding compost, used at 100% or in a 50% / 50% mixture with a commercial substrate of bark, peat, and sand, was unacceptable for commercial production. Although the cost per flat of the food residuals compost was slightly higher than that of the commercial peat-based medium, for organic production this additional cost may be insignificant since there are limited potting media options, and price premiums are typically available.

Precision agriculture is a proposed approach for achieving sustainable agriculture. Site-specific crop management (or site-specific management, SSM) refers to the application of precision agriculture to crop production. Site-specific crop management utilizes rapidly evolving information and electronic technologies to modify the management of soils, pests and crops in a site-specific manner as conditions within a field change spatially and temporarily. Geospatial measurements of apparent soil electrical conductivity (ECa) are the most reliable and frequently used measurements to characterize within-field variability of edaphic properties for application to SSM. The collection of papers that comprises this special issue of Computers and Electronics in Agriculture provides a review of the current technology and understanding of geospatial measurements of ECa and current approaches for their application in SSM. The objective of this preface is to run a thread through the papers to show their interrelationship and to identify significant points. The spectrum of topics covered by the papers include: (i) a review of the use of ECa measurements in agriculture, (ii) multi-dimensional ECa modeling and inversion, (iii) theory and principles elucidating the edaphic properties that influence the ECa measurement, (iv) ECa survey protocols for characterizing spatial variability, (v) ECa-directed response surface sampling design, (vi) designing and evaluating field-scale experiments using geospatial ECa measurements, (vii) mapping of soil properties with ECa, (viii) spatially characterizing ECa and water content with time domain reflectornetry (TDR), (ix) delineating productivity and SSM zones and (x) SSM methods for reclaiming salt-affected soils. The greatest potential for the application of geospatial measurements of ECa in SSM is to provide reliable spatial information for directing soil sampling to identify and characterize the spatial variability of edaphic properties influencing crop yield. This in turn can be used to delineate SSM units, which are key components of SSM. The future of SSM depends upon the continued development and integration of information and electronic technologies that can identify and characterize, both temporally and spatially, not only edaphic properties but also topographical, biological, meteorological and anthropogenic factors influencing within-field variations in crop productivity. The implementation of global positioning system (GPS)-controlled variable-rate equipment will need spatial information to effectively determine input application rates. Because of their reliability, ease of measurement and flexibility, geospatial ECa data will undoubtedly contribute a significant portion of the spatial soils-related information needed to direct variable-rate equipment.

Apparent soil electrical conductivity is influenced by a combination of physico-chemical properties including soluble salts, clay content and mineralogy, soil water content, bulk density, organic matter, and soil temperature; consequently, measurements of ECa have been used at field scales to map the spatial variation of several edaphic properties: soil salinity, clay content or depth to clay-rich layers, soil water content, the depth of flood deposited sands, and organic matter. In addition, ECa has been used at field scales to determine a variety of anthropogenic properties: leaching fraction, irrigation and drainage patterns, and compaction patterns due to farm machinery. Since its early agricultural use as a means of measuring soil salinity, the agricultural application of ECa has evolved into a widely accepted means of establishing the spatial variability of several soil physico-chemical properties that influence the ECa measurement. Apparent soil electrical conductivity is a quick, reliable, easy-to-take soil measurement that often, but not always, relates to crop yield. For these reasons, the measurement of ECa is among the most frequently used tools in precision agriculture research for the spatio-temporal characterization of edaphic and anthropogenic properties that influence crop yield. It is the objective of this paper to provide a review of the development and use of ECa measurements for agricultural purposes, particularly from a perspective of precision agriculture applications. Background information is presented to provide the reader with (i) an understanding of the basic theories and principles of the ECa measurement, (ii) an overview of various ECa measurement techniques, (iii) applications of ECa measurements in agriculture, particularly site-specific crop management, (iv) guidelines for conducting an ECa survey, and (v) current trends and future developments in the application of ECa to precision agriculture. Unquestionably, ECa is an invaluable agricultural tool that provides spatial information for soil quality assessment and precision agriculture applications including the delineation of site-specific management units. Technologies such as geo-referenced ECa measurement techniques have brought precision agriculture from a 1980's concept to a promising tool for achieving sustainable agriculture.

Apparent soil electrical conductivity (ECa) is a quick, reliable measurement that is frequently used for the spatio-temporal characterization of edaphic (e.g., salinity, water content, texture, and bulk density) and anthropogenic (e.g., leaching fraction) properties. It is the objective of this paper to provide the protocols for conducting a field-scale ECa survey (Part I) and apply these protocols to a soil quality assessment in central California's San Joaquin Valley (Part 11). The protocols are comprised of eight general steps: (i) site description and ECa survey design; (ii) ECa data collection with mobile GPS-based equipment; (iii) soil sampling design; (iv) soil core sampling; (v) laboratory analysis; (vi) calibration of ECa to ECe; (vii) spatial statistical analysis; (viii) GIS database development and graphic display. For each outlined step, detailed discussion and guidelines were presented. The developed protocols provide the guidelines to assure reliability, consistency, and compatibility of ECa survey measurements and their interpretation. Published by Elsevier B.V.

However, inconsistencies in the measurement and interpretation of field- and landscape-scale geospatial ECa measurements have resulted in data sets that are unreliable and/or incompatible. These inconsistencies are, in part, a consequence of the lack of ECa-survey protocols that provide standardized guidelines to assure reliability, consistency, and compatibility. It is the objective of this paper to apply ECa-survey protocols to a soil quality assessment to demonstrate their utility in characterizing spatial variability. The soil quality assessment was conducted on a 32.4-ha field on the westside of central California's San Joaquin Valley where a mobile electromagnetic induction (EM) survey was performed following outlined protocols. The EM survey consisted of ECa measurements taken at 22,177 locations in April 2002. A response-surface sampling design was used to identify 40 sites where soil-core samples were taken at 0.3-m increments to a depth of 1.2 m. Duplicate samples were taken at eight sites to evaluate the local-scale variability. Soil samples were analyzed for a variety of physico-chemical properties associated with soil quality for an and zone soil. Analysis characterized the soil as montmorillonitic, saline, and sodic with ECa (electrical conductivity of the saturation extract) varying from 4.83 to 45.3 dS m(-1), SAR (sodium adsorption ratio) from 5.62 to 103.12, and clay content from 2.5 to 48.3%. Spatial trends showed high areas of salinity and SAR in the center of the southern half of the study area. Strong correlation was obtained between ECa and the soil properties of the saturation extract (ECe; Cl-, HCO3-, SO42-, Na+, K+, and Mg2+), exchangeable Na+, and SAR. Other properties were poorly correlated, including: volumetric water content (theta(v)), bulk density (D-b), percent clay (% clay), saturation percentage (SP), exchangeable sodium percentage (ESP), Mo, CaCO3, gypsum, total N, Ca2+ in the saturation extract, and exchangeable cations (K+, Ca2+, and Mg2+). The spatiai. distribution of the poorly correlated properties is not as well represented with a response-surface sampling design suggesting the need for a complementary stratified random sample design.

Additionally, a general model for the functional relationship between the soil property and the sensor data is often known a priori, but the exact parameter estimates associated with the model must still be determined via some type of site-specific sampling strategy. The main objective of this paper is to present an objective sampling and simplified modeling strategy for predicting soil property information from such spatially referenced sensor data. Some common types of spatial linear prediction models and linear geostatistical models are reviewed, and the assumptions needed to reduce these more complicated models to a spatially referenced, ordinary linear regression model (LR) are discussed. Next, a model-based sampling strategy for estimating an ordinary linear regression model in the spatial setting is described. This sampling strategy incorporates a traditional response surface design into an iterative, space-filling type algorithm for purposes of selecting sample site locations that are (i) nearly optimal with respect to matching the selected response surface design levels and (ii) physically separated far apart as possible to ensure the best chance that the independent error assumption is adequately met. This strategy can in principal be used to select a minimal number of optimal sample site locations that satisfy the residual independence assumptions in the ordinary model. A detailed case study of a salinity survey using electromagnetic induction (EM) and four-electrode sensor data is then presented. These case study results confirm that the sampling strategy was highly effective at ensuring efficient regression model parameter estimates and a reliable salinity prediction map. An additional simulation study confirmed the effectiveness of this model-based strategy over a more traditional simple random sampling strategy with respect to four regression model design criteria. Under the right conditions, this methodology should be applicable to many types of precision farming survey applications where soil property/sensor data prediction models need to be fitted using only a limited number of soil samples.

While promoting a realistic systems perspective, field-scale experiments do not lend themselves to the traditional design concepts of replication and blocking. Previously, a farm-scale dryland experiment in northeastern Colorado was conducted to evaluate apparent electrical conductivity (ECa) classification (within-field blocking) as a basis for estimating plot-scale experimental error. Comparison of mean-square (MS) errors for several soil properties and surface residue mass measured at this site, with those from a nearby plot-scale experiment, revealed that ECa-classified within-field variance approximates plot-scale experimental error. In the present study, we tested these findings at a second and disparate experimental site, Westlake Farms (WLF) in central California. This 32 ha site was ECa mapped and partitioned into four and five classes using a response-surface model. Classification based on ECa significantly delineated most soil properties evaluated (0-0.3 and/or 0-1.2 m) and effectively reduced MS error (P <= 0.10). The MS's for several soil properties evaluated at the site were then compared with those of an associated plot-scale experiment; most MS's were not significantly different between the two levels of scale (P <= 0.05), corroborating results from the Colorado experiment. These findings support the use of within-field ECa-classified variance as a surrogate for plot-scale experimental error and a basis for roughly evaluating treatment differences in non-replicated field-scale experiments. This alternative statistical design may promote field-scale research and encourage a reversal in research direction wherein research questions identified in field-scale studies are pursued at the plot-scale.

From simultaneous knowledge of theta and ECa, the soil solution electrical conductivity ECs and even the concentration of specific ionic constituents such as NO3-nitrogen may be estimated through soil-specific calibration. This paper provides an introduction, some theoretical background, and a practical review of the TDR method for spatially characterizing theta, ECa, and related attributes in soils. Time domain reflectometry measurement principles for determining theta, ECa, and ECs, along with suggestions for inferring matric potential from dielectric measurements, are addressed. We discuss point, handheld, and vehicle-based measurement methods. Applications of TDR to spatially characterize theta in a hilly agricultural field using TDR and gravimetric methods, and to monitor theta and nitrate concentrations at three depths under peppermint production, are presented. A pickup-mounted TDR measured theta at 100 m x 100 m grid spacing in two wheat fields in north-central Montana. Soil theta, as well as NO3-N, grain yield, and grain protein increased from upper to lower slopes. Soil theta early in the growing seasons appeared critical to final yields in this rainfed system. An array of fixed TDR probes was monitored over two growing seasons under peppermint in northwest Montana, to estimate theta, ECs, and NO3-N every 6 h at 12 field locations. Although the field soils appeared uniform, measured spatial patterns of theta, ECs, and NO3-N were highly space- and time-variant. These results indicate that TDR is a potentially useful tool for precision agriculture, and that fixed TDR arrays could serve as real-time monitoring systems for water and fertilizer salts in soil profiles. The primary limitation of the TDR method for spatially characterizing theta and EC at soil management scales using fixed arrays is the cable length limitation of about 20-30 m. Mobile platforms are of high interest, and prototype designs have been reported in the literature. Truly 'on-the-fly' TDR measurements for large-scale applications may be feasible in the near future.

Commercially available ECa sensors can efficiently and inexpensively develop the spatially dense datasets desirable for describing within-field spatial soil variability in precision agriculture. The objective of this research was to relate ECa data to measured soil properties across a wide range of soil types, management practices, and climatic conditions. Data were collected with a non-contact, electromagnetic induction-based ECa sensor (Geonics EM38) and a coulter-based sensor (Veris 3100) on 12 fields in 6 states of the north-central United States. At 12-20 sampling sites in each field, 120-cm deep soil cores were obtained and used for soil property determination. Within individual fields, EM38 data collected in the vertical dipole orientation (0-150 cm depth) and Veris 3100 deep (0-100cm depth) data were most highly correlated. Differences between ECa sensors were more pronounced on more layered soils, such as the claypan soils of the Missouri fields, due to differences in depth-weighted sensor response curves. Correlations of ECa with clay content and cation exchange capacity (CEC) were generally highest and most persistent across all fields and ECa data types. Other soil properties (soil moisture, silt, sand, organic C, and paste EC) were strongly related to ECa in some study fields but not in others. Regressions estimating clay and CEC as a function of ECa, across all study fields were reasonably accurate (r(2) >= 0.55). Thus, it may be feasible to develop relationships between ECa and clay and CEC that are applicable across a wide range of soil and climatic conditions. (c) 2004 Elsevier B.V. All rights reserved.

This investigation was conducted to answer the question of whether apparent soil electrical conductivity (ECa) and elevation could be used to delineate productivity zones (SPZ) for claypan soil fields that would agree with productivity zones delineated from yield map data (YPZ). Ten and seven years of combine-monitored yield maps were available for two Missouri claypan soil fields, designated Field 1 and Field 2, respectively. The fields were generally cropped in corn and soybean. Soil ECa data were collected with a non-contact, electromagnetic induction-based ECa sensor (Geonics EM38) and a coulter-based sensor (Veris model 3 100). Elevation data were collected using a real-time kinematic GPS. Unsupervised fuzzy c-means clustering was independently used both on yield data to delineate three YPZ and on combinations of ECa and/or elevation data to delineate three SPZ. Outcomes of YPZ and SPZ were matched and agreement calculated with an overall accuracy statistic and a statistical index called the Kappa coefficient. Best performing combinations of ECa and elevation variables gave 60-70% agreement between YPZ and SPZ. We consider this level of agreement promising, especially considering that there were many other yield-limiting factors unrelated to ECa and elevation. Generally, multiple variables of ECa and elevation were better than a single variable for generating SPZ. The specific combinations of ECa and/or elevation variables that gave highest agreement between YPZ and SPZ were field specific. Based on these findings, we conclude ECa and elevation measurements can be reliably used for creating productivity zones on claypan soil fields. Published by Elsevier B.V.

In this study, we applied cluster analysis of multi-year soybean (Glycine max [L.] Merr.) yield to partition a field into a few E groups or clusters with similar temporal yield patterns and investigated the relationships between these yield clusters and the easily measured properties elevation (and the simple terrain attributes derived from elevation) and apparent soil electrical conductivity (ECa). The analysis was applied to 5 years of soybean yield data collected from 224 plots arranged along eight transects spanning a 16-ha field. The partitioning phase of cluster analysis revealed that the 224 locations were best grouped into five clusters. These clusters were roughly aligned with landscape position and were characterized by the yield response to growing season precipitation above or below the 40-year average. Canonical discriminant functions constructed from the simple terrain attributes and ECa predicted correct cluster membership for 80% of the plots. While not perfect, the discriminant functions were able to capture the major characteristics of the yield cluster distribution across the field, indicating that these easily measured variables are strongly related to soybean yield. Applying the functions with high-resolution terrain and ECa attributes, we mapped soybean yield zones within the 16-ha field and an adjacent 16-ha field where multi-year yield data were not available. Cluster analysis of multi-year yield data and easily measured terrain and soil date may be useful in constructing effective management zones within fields and once developed can be applied to similar fields lacking detailed spatial yield data.

The responses of sugar beets to salinity and to residual and applied soil N were studied at sites in California's Imperial and San Joaquin Valleys to evaluate the potential of electromagnetic induction (EMI) techniques for SSM. Electromagnetic induction was used to create geo-referenced assessments of apparent soil electrical conductivity (ECa) and correlated soil properties in salt-affected fields in the Imperial (IV) and San Joaquin (SJV) Valleys. Soils at the two sites were primarily fine, smectitic (calcareous) thermic, vertic Torifluvents and Fluvequents, respectively. Two crops were grown in the IV and one in the SJV. Root and gross sugar yields were evaluated at field scale using a yield monitor and in subplots centered on soil sampling locations chosen using ESAP-95 (v. 2.01) software that were harvested by hand. Average subplot root yields differed from field-scale averages derived from the yield monitor by less than 4% for all three crops. In the IV field, average salinity increased with depth, indicating leaching of salts. The natural logs of electrical conductivity of the saturation paste extract (ECe) and saturation percentage (SP) were strongly correlated with measured ECa (r=0.97 and r=0.86, respectively) and nitrate was moderately correlated (r=0.55). Root and sugar yields declined at the higher salinity levels from 18.0 to 8.0 mg ha(-1). The SJV site was poorly drained and leaching was not apparent. ECe was strongly correlated with ECa (r = 0.94), but SP was not (r = 0.20). Gross sugar yields apparently were influenced by SP rather than by ECe and varied from 2.9 to 14.1 mg ha(-1). Where crop growth and yield are influenced by salinity, EMI is useful for estimating optimum fertilizer N application rates and for identifying areas of the field that will have unprofitable yields. Irrigation might be withheld from these areas and the water saved for other beneficial uses. (c) 2004 Published by Elsevier B.V. C1 Univ Calif Davis, Dept Agron & Range Sci, Davis, CA 95616 USA.

In this paper, we examine three applications of EM surveying used in and southwestern US agriculture: repetitive salinity mapping, soil texture mapping, and locating buried tile lines. The basic statistical modeling techniques associated with each application are described and then demonstrated using data from three different field survey projects. In the first study, pre- and post-EM surveys are used to quantify the degree of salt removal from a field leaching event. These survey results demonstrate that the degree of salt removal was spatially variable and that the leaching process was not successful in sub-areas of the field that exhibited high pre-survey salinity concentration levels. The second study demonstrates the use of EM survey data for precision soil texture mapping under non-saline conditions, and illustrates how texture prediction maps can be generated from EM survey data. The final study represents an example of how EM survey data can be used to precisely locate the positions of buried tile lines. In this latter study, two different EM survey data sets that were collected 1 year apart produced estimates of tile line positions within 1 m of each other, validating the reliability and repeatability of the proposed tile line identification strategy. These projects demonstrate three applications of ECa surveying techniques used to derive spatial information that aids in the effective management of agricultural fields. Published by Elsevier B.V.

Despite this overall decline, a recent north-eastern expansion of the breeding range has been proposed, and some researchers have suggested that the eastern Ontario population may be acting as a source population maintaining sink populations elsewhere. However, little is known about either the geographic distribution of genetic variation or dispersal in these birds. We assayed variation in five microsatellite loci and a 366 base-pair fragment of the mitochondrial control region among 154 cerulean warblers from five populations throughout the breeding range. No evidence of population genetic structure was found. Assignment tests suggested that six individuals were either inter-population migrants or descendants of recent migrants. The lack of population genetic structure is probably due to a combination of historical association and contemporary dispersal. Population decline does not appear to have reduced genetic variation yet. Overall results suggest that cerulean warblers from Ontario, Illinois, Arkansas and Tennessee should be considered a single genetic management unit for conservation.

Merr.] is an important protein source in human diets and animal rations. Additionally, human consumption of soybean protein is reported to provide specific health benefits. Since methionine and cysteine contents limit the nutritional value of soybean, efforts involving both traditional breeding and genetic engineering have been employed in attempts to increase the presence of these essential amino acids. Traditional breeding has been primarily utilized to increase the total protein content but not to enhance the sulfur amino acid content of soybean. Although mutagenesis in conjunction with traditional breeding is a viable approach for enhancing the sulfur amino acid content of soybean, genetic engineering appears to be a more realistic approach. Introduction of methionine-rich heterologous proteins has resulted in a modest increase of this amino acid in soybean. Either elevating the expression of endogenous methionine-rich proteins or introducing synthetic proteins containing a high percentage of essential amino acids are other possible approaches that may increase the nutritional quality of the seed. Even though considerable progress has been made in enhancing the methionine content of soybean, several obstacles remain. A thorough understanding the sulfur assimilatory pathway in soybean is a prerequisite for improving the sulfur amino acid content. Expression of feedback-insensitive forms of serine acetyl transferase and O-acetylserine (thiol) lyase, two key enzymes in sulfur assimilatory pathway, could lead to an increase in the availability of sulfur amino acids. An adequate supply of sulfur amino acids in developing seeds may facilitate accumulation of sulfur-rich proteins to a level sufficient to meet the nutritional requirement of livestock and poultry.

Merr.] products in processed foods poses a potential threat to soybean-sensitive, food-allergic individuals. Clinical symptoms of soybean allergy can be manifested as gastric distress or atopic dermatitis and, while usually not life threatening, suspected cases of anaphylaxis have been reported. In vitro assays of soybean seed proteins with sera collected from soybean-sensitive individuals have shown that major storage proteins as well as other minor seed proteins account for IgE binding. Gly in Bd 30k, a member of the papain superfamily of cysteine proteases, also referred to as P34, has been identified as a major allergen in soybean seeds. We have used gene silencing to eliminate accumulation of P34/Gly in Bd 30k in transgenic soybean. These transgenic plants, producing P34/Gly in Bd 30k-null seeds, lacked any obvious developmental or phenotypic differences when compared with control plants. The production of a P34/Gly in Bd 30k-null line eliminates one of the primary allergens present in soybean seeds. C1 USDA ARS, Plant Genet Unit, Donald Danforth Plant Sci Ctr, St Louis, MO 63132 USA.

The literature contains two prior publications reporting the location of QTLs affecting resistance to sheath blight (SB) disease in rice (Oryza sativa L.), but lack of agreement between QTLs in the studies left all 12 unconfirmed, limiting the potential of marker-assisted selection of this trait with worldwide importance. The earlier linkage analyses were imprecise due to heterozygosity, segregation, and limited plot size and replication. We evaluated a replicated set of pure-breeding recombinant inbred lines (RILs) to increase reliability of the quantitative disease data and in turn improve accuracy of the QTL mapping. The RILs were F-2:10 descendants from an early-generation 'Lemont' X 'Teqing' population wherein SB resistance QTLs (SB-QTLs) were first identified. The present study confirmed the location and effect of six SB-QTLs, confirmed the existence but not the specific location of another, and identified eight new loci. Three of the confirmed QTLs were also found to be independent from undesirable plant height and maturity effects. This research demonstrated the importance of using replicated phenotypic data for reliably establishing the identity and effect of putative QTLs for complex traits such as SB resistance. Further marker development to facilitate marker-assisted selection of these three SB-QTLs is warranted. C1 USDA ARS, Rice Res Unit, Beaumont, TX 77713 USA.

In the southwestern USA and other regions where peanut is grown, diseases caused by fungi are a major threat to profitable production. Transgenic peanut lines possessing fungal resistance genes offer an alternative to traditional resistance and fungicide application in managing fungal diseases. Thirty-two transgenic peanut lines containing antifungal genes (a rice chitinase and/or an alfalfa glucanase) were evaluated for their reaction to Sclerotinia blight caused by Sclerotinia minor Jagger in small field plots (6.1 by 7.6 m) for 3 yr. Peanut lines were arranged in a complete randomized block design with three replications. Disease incidence was recorded throughout the growing season and data were analyzed for statistical significance. Over the 3-yr period, average disease incidence for the most resistant lines-188, Southwest Runner, 416, 540, and 654-was 0.0, 1.0, 10.0, 14.0, and 16.0%, respectively. The cultivar Okrun was most susceptible with an average disease incidence of 58.0%. All other lines had varying degrees of resistance but averaged at least 15.5% less disease than Okrun over the 3-yr period. Transgenic peanut lines with partial resistance to Sclerotinia blight were identified which may be useful in traditional breeding programs for fungal resistance.

CWG-R is an experimental population of crested wheatgrass [Agropyron cristatum (L.) Gaertn.] from Iran that has shown potential as a low-maintenance turf. The objective of this research was to estimate the genetic variation for turf traits within the CWG-R population when evaluated under a reduced-maintenance regimen. Ninety CWG-R clonal lines were established in 1998 near Logan, UT, as spaced-plant plots in a RCB design with four replicates. Maintenance of 50% ET0 replacement, 97.74 kg of nitrogen ha(-1) yr(-1), and mowing at 7.62 cm was approximately 40% lower than typical for high-input Kentucky bluegrass (Poa pratensis L.) turf. Critical turf traits, including spring regrowth, season-long (March-October) and mid-summer (June-July) turf quality, color, and rhizomatous spread were evaluated in 1999 and 2000. Significant genetic variation among clonal lines was evident with broad-sense heritabilities of 0.65, 0.76, 0.45, and 0.76 for spring regrowth, season-long turf quality, color, and rhizomatous spread, respectively. Several clonal lines remained green throughout the summer months and maintained acceptable turf quality and color ratings during the critical mid-summer period. The high broad-sense heritability estimates within this population indicate potential for successful improvement of critical turf traits by phenotypic selection. These results indicate that that CWG-R could be an important low-maintenance turf-type crested wheatgrass germplasm. C1 USDA ARS, Forage & Range Res Lab, Logan, UT 84322 USA.

An ability to predict the onset and termination of growth of component species would facilitate timing of management interventions to minimize harmful competition in mixed pastures. Experiments were undertaken in controlled environment to assess the use of accumulated temperature values to indicate development stages in three cool-season grass species, and to evaluate the consistency of this relation under a range of temperature regimes that included variable exposure to below-freezing, temperatures. When grown under light and dark temperature regimes of 22.5 and 7.5, 17.5 and 12.5, 15.0 and 0.0, or 10.0 and 5.0 degrees C, respectively, leaf appearance in Italian ryegrass (Lolium multiflorum Lam.), tall fescue (Festuca arundinacea Schreb), and tall wheatgrass [Elytrigia elongata (Host) Nevski] showed a close linear relationship with accumulated temperature, within each temperature regime. The interval between appearance of successive leaves on seedling mainstem (phyllochron) was increased by increased average daily temperature. In seedlings grown under a 15.0 and 0.0 degrees C temperature regime, phyllochron was increased linearly by up to four 15-h exposures to -5.0 or -7.5 degrees C dark-cycle temperatures in successive 24-h periods. The effects of variation in mean daily temperature and of plant exposure to below-freezing temperature on phyllochron should be considered if accumulated temperature is used to predict development stage of cool-season grasses in the field.

Merr.] seed is phytate P, which cannot be readily digested by nonruminant livestock, such as swine and poultry. The phytate P in soybean lines homozygous for the recessive alleles pha1 and pha2 is reduced to about 25% of the total P. The objective of this study was to determine the influence of low phytate (LP) on agronomic and seed traits of soybean. Three populations were developed by crossing three cultivars with normal phytate (NP) to the LP line CX1834-1-6. From each population, 10 LP and 10 NP lines were selected and grown in replicated tests at three Iowa environments during 2003. The mean total P of the LP and NP lines was not significantly different, but the mean phytate P, inorganic P, and other P were significantly different for the two types of lines in the three populations. The mean seedling emergence of the LP lines was 45% compared with 68% for the NP lines. The mean differences between the LP and NP lines for the other agronomic and seed traits were not significant in one or more of the populations. On the basis of these results, reduced seedling emergence will be a major factor to consider in the development of commercially viable cultivars with the pha1pha1pha2pha2 genotype for LP.

All ancestral lines tested were susceptible to BPMV and TRSV. Only one ancestor, 'Tanner', was resistant to TSV. On the basis of cultivar registration articles through 2002, there were 15 public soybean cultivars with reported resistance to SMV. The possible donors of resistance for each were identified. Two soybean ancestors, CNS and Ogden, were the most important possible sources of SMV resistance genes in U.S. commercial soybean cultivars, as the pedigree of 75 and 56% of the reported resistant cultivars contained CNS and Ogden, respectively. In most of the cultivar registration articles, reactions to SMV were not reported.

An experiment was conducted to determine the effect of applying solid cattle (Bos spp.) manure (SCM), liquid swine (Sus spp.) effluent (LSE), or commercial fertilizer (CF; urea) at three application rates (0, 120, or 240 kg N ha(-1)) on the yield, plant canopy height, and nutritive value (crude protein, CP; and in vitro organic matter digestibility, IVOMD) of buffalograss [Buchloe dactyloides (Nutt.)

For all N sources, seasonal dry matter yield (DMY), canopy height, and CP increased as N rate increased during each of the 3 yr following establishment. However, as the buffalograss stand aged, the yield, canopy height, and nutritive value of forage declined. Given the availability of livestock manure in the High Plains region of the USA and the need to recycle this by-product from confined animal feeding operations, the application of livestock manure to buffalograss grown with irrigation for hay or pasture could be a viable and sustainable production system. Future work should address the long-term effects of applying livestock manure to soils in relation to nutrient loading and water quality. C1 USDA ARS, So Plains Range Res Stn, Woodward, OK 73801 USA.

Nine genotypes from four combinations of ecotype and morphological type were harvested once yearly in autumn for 3 or 4 yr at five locations across Texas, Arkansas, and Louisiana that varied in latitude and precipitation. Genotypes were evaluated for dry matter yield (DMY), plant density, tiller density, lodging, and rust (caused by Paccinia spp.) infection. Genotype X environment (G X E) interactions were identified for most traits. Biomass yield of all genotypes tended to increase with latitude, but lowland morphological types may have been more sensitive than upland morphological types to differences in moisture availability. Yield (5.82 vs. 14.97 Mg ha(-1), respectively) and persistence (final stand density, 3.99 vs. 5.96 plants m(-2)) were lower for upland than for lowland genotypes, particularly at higher rainfall and more southern sites. Lowland genotypes were often able to compensate for stand thinning by increasing individual plant size, but upland genotypes were not. Lodging and rust scores were higher for upland than for lowland genotypes. Yield (13.65 vs. 9.75 Mg ha(-1)) and final plant density (5.58 vs. 4.95 plants m(-2)) were higher for southern than northern ecotypes. The southern-lowland combination exhibited the best yield and persistence over the study region, and genotypes within this group exhibited variability in yield among sites. Therefore, development of switchgrass cultivars for biomass production in the southern USA should focus on the southern-lowland genotypes. C1 USDA ARS, AFSRC, Beaver, WV 25813 USA.

Compared with northern ecotypes, southern ecotypes had greater lignocellulose yields (4.95 vs. 6.85 Mg ha(-1)), greater removal rates of soil N (60 vs. 76 kg ha(-1)) and P (8 vs. 11 kg ha(-1)), greater moisture concentrations (417 vs. 445 g kg(-1)), and lower ash concentrations (45 vs. 40 g kg(-1)). Lignocellulose yield paralleled dry matter yield (DMY) patterns. Switchgrass biofuel production efforts in the south-central USA should focus on improving DMY of southern lowland genotypes to maximize lignocellulose yields, but management factors may be more effective in optimizing moisture, ash, and mineral concentrations for combustion.

The objective was to determine whether soil management practices affect canopy position specific fiber properties on two soils. A 3-yr field study was conducted with plots on two soil types [Bonneau loamy sand (loamy, siliceous, thermic Arenic Paleudult) and Norfolk loamy sand (fine-loamy, siliceous, thermic Typic Kandiudult)]. Treatments in the study were cover crop [none and rye (Secale cereale L.)] and tillage system (disk tillage and conservation tillage). Fiber properties were determined from hand picked samples at three canopy positions (first sympodial position bolls at Mainstem Nodes 6 and 7, 9, and 10, and 12 and 13). Yield and fiber properties of the whole crop were determined after machine harvesting. In two of the 3 yr, conservation tillage had 34% higher yield than disk tillage. Conservation tillage had higher fiber length uniformity every year, but no consistent differences between tillage systems occurred for the other fiber properties. Cover crop did not influence within-canopy fiber properties. When differences occurred between tillage systems for fiber length at specific canopy positions, fibers from conservation tillage were about 1 rum longer than fibers from disk tillage. Fiber length uniformity results were similar to those for fiber length. Disk tillage resulted in cotton with 0.22 lower micronaire units than conservation tillage at Mainstem Nodes 6 and 7 when rainfall was plentiful in 1997, but had micronaire that was 0.82 units higher than conservation tillage at that canopy position during the dryer year of 1998. Within canopy variability for micronaire was greater on the more drought susceptible Bonneau soil than on the Norfolk soil. Results indicate that tillage management can influence canopy position specific fiber property distribution. C1 USDA ARS, Coastal Plain Soil Water & Plant Res Ctr, Florence, SC 29501 USA.

Leaf rust resistance gene Lr51, located within a segment of Triticum speltoides Taush chromosome IS translocated to the long arm of chromosome 1B of bread wheat, is resistant to the current predominant races of leaf rust in the USA. The objectives of this study were to determine the genetic length of the translocated IS segment, develop a PCR marker for Lr51, and use this marker to generate isogenic lines for this gene. Characterization of two translocation lines (F-7-3 and F-7-12) with 10 molecular markers indicated that F-7-3 has an interstitial T. speltoides chromosome segment of 14 to 32 cM long including loci XAga7 and Xmwg710, whereas line F-7-12 has a complex series of translocations among chromosomes of homeologous group 1. On the basis of the DNA sequence of the A, B, D, and S alleles of the XAga7 locus, we designed a cleavage amplified polymorphic sequence (CAPS) marker for the S genome allele. Primers S30-13L and AGA7-759R preferentially amplified the XAga7 1S (819 bp) and 1B alleles (783 bp). These amplification products can be separated in agarose gels after digestion with PstI or BamHI restriction enzymes. This CAPS marker was validated in a collection of 32 common wheat cultivars and was used to develop three pairs of hard red spring isogenic lines from the donor parent F-7-3. These isogenic lines will be valuable for future assessment of the effect of this chromosome introgression on agronomic performance and end-use quality.

CI 13227 was previously reported to provide the highest level of slow leaf-rusting resistance. The objective of this study was to characterize the slow leaf-rusting resistance conferred by CI 13227 using molecular markers. A population of recombinant inbred lines (RILs) derived from CI 13227/Suwon 92 was evaluated for final severity (FS), area under disease progress curve (AUDPC), infection rate (IR), and infection duration (ID) of leaf rust. Four hundred fifty-nine amplified fragment length polymorphism (AFLP) markers and 28 simple sequence repeat (SSR) markers were analyzed in the population. Two quantitative trait loci (QTL), designated as QLr.osu-2B and QLr.osu-7BL, were consistently associated with AUDPC, FS, and IR of leaf rust, caused by Puccinia triticina (previously P. recondita Rob. Ex Desm. f. sp. tritici). The percentages of phenotypic variance explained by each QTL varied with experiments and traits, ranging from 13.4 to 18.8% for AUDPC, 12.5 to 20.8% for FS, and 12.9 to 16.1% for IR. The third QTL for leaf rust ID, designated as QLrid.osu-2DS, was located on chromosome 2DS and explained 26.4 and 21.47% of the phenotypic variance in 1994 and 1995, respectively. Both the QTL and correlation analysis indicate reasonable progress in leaf-rusting resistance by selecting for final severity. SSR markers closely associated with QLr.osu-2B or QLr.osu-7BL have potential to be used in marker-assisted selection (MAS) for durable leaf rust resistant cultivars.

Seeds from four different accessions (collected in 1987, 1990, 1993 and 1998) adjusted to different water contents were tested for survival following cryostorage. Water content was a significant determining factor with survival of cryostored seeds declining rapidly at water contents above c. 18%. These water contents were deemed as critical water contents and were supported by DSC scans showing high endothermic peaks indicating ice crystallisation. In some instances, survival of cryostored seeds also declined at low water contents. Seeds from 1990 had a lower than expected survival compared to the other accessions. This may have resulted from the higher lipid content of seeds from this accession, or the reduced germination and vigour of these seeds prior to cryostorage.

Microbial activity in aquifers is usually limited by substrate availability, and biobarriers stimulate microbial activity by providing a substrate, for these studies soybean oil was used. Water containing, 10 mg L(-1) selenite-Se was pumped through the biobarriers for 74 days and the amount present in the effluent monitored. The amounts remained high for the first 2 weeks of the study but then declined. From day 28 until the end of the study the amount of selenite-Se in the column effluents averaged 0.20 +/- 0.04 mg L(-1). a decrease of approximately 98%. At the end of the Study about half of the selenite-Se applied to the columns was recovered as immobilized selenium trapped by the biobarrier. This study Suggests that biobarriers containing vegetable oil might be used as a process for removing selenite from contaminated groundwater. C1 USDA ARS, NRRC, Ft Collins, CO 80526 USA.

Cultures that were provided with glucose and mannose had little beta-glucanase activity even though both sugars were utilized simultaneously. The observation that glucose and mannose were utilized simultaneously indicated that P-glucanase expression was not merely a simple induction or inducer exclusion. When glucose was added to cultures growing on rnannose, hexose flux through the glucomannokinase increased 1.5-fold, and this increase was associated with an almost immediate decrease in beta-glucanase mRNA. After only three generation (doubling) times, the amount of beta-glucanase mRNA was comparable to that observed in cells rowing only with glucose. These results indicate that beta-glucanase activity is transcriptionally regulated. However, further work will be needed to define more precisely the nature of this regulation and to identify the intermediate in this response.

The maintenance of a constant flow of cells through the meristem depends on coordination of two antagonistic processes: self-renewal of the stem cell population and initiation of the lateral organs. This coordination is stringently controlled by gene networks that contain both positive and negative components. We have previously defined the ULTRAPETALA1 (ULT1) gene as a key negative regulator of cell accumulation in Arabidopsis shoot and floral meristems, because mutations in ULT1 cause the enlargement of inflorescence and floral meristems, the production of supernumerary flowers and floral organs, and a delay in floral meristem termination. Here, we show that ULT1 negatively regulates the size of the WUSCHEL (WUS)-expressing organizing center in inflorescence meristems. We have cloned the ULT1 gene and find that it encodes a small protein containing a B-box-like motif and a SAND domain, a DNA-binding motif previously reported only in animal transcription factors. ULT1 and its Arabidopsis paralog ULT2 define a novel small gene family in plants. ULT1 and ULT2 are expressed coordinately in embryonic shoot apical meristems, in inflorescence and floral meristems, and in developing stamens, carpels and ovules. Additionally, ULT1 is expressed in vegetative meristems and leaf primordia. ULT2 protein can compensate for mutant ULT1 protein when overexpressed in an ult1 background, indicating that the two genes may regulate a common set of targets during plant development. Downregulation of both ULT genes can lead to shoot apical meristem arrest shortly after germination, revealing a requirement for ULT activity in early development.

Meristems must maintain a balance between stem cell renewal and organ initiation. In fasciated mutants, organ initiation fails to keep pace with meristem proliferation. The thick tassel dwarf1 (td1) mutation of maize affects both male and female inflorescence development. The female inflorescence, which results in the ear, is fasciated, with extra rows of kernels. The male inflorescence, or tassel, shows an increase in spikelet density. Floral meristems are also affected in td1 mutants; for example, male florets have an increase in stamen number. These results suggest that td1 functions in the inflorescence to limit meristem size. In addition, td1 mutants are slightly shorter than normal siblings, indicating that td1 also plays a role in vegetative development. td1 encodes a leucine-rich repeat receptor-like kinase (LRR-RLK) that is a putative ortholog of the Arabidopsis CLAVATA1 protein. These results complement previous work showing that fasciated ear2 encodes a CLAVATA2-like protein, and suggest that the CLAVATA signaling pathway is conserved in monocots. td1 maps in the vicinity of quantitative trait loci that affect seed row number, spikelet density and plant height. We discuss the possible selection pressures on td1 during maize domestication. C1 Univ Cologne, Inst Entwicklungsbiol, D-50923 Cologne, Germany.

In this paper we use data from 19 of those sites to characterize patterns and rates of coarse sediment transport for a range of channel types and sizes, including step-pool, plane-bed, pool-riffle, and near-braided channels. This effort builds upon previous work where we applied a piecewise regression model to (1) relate How to rates of bedload transport and (2) define phases of transport in coarse-grained channels. Earlier, the model was tested using bedload data from eight sites on the Fraser Experimental Forest near Fraser, Colorado. The analysis showed good application to those data and to data from four supplementary channels to which the procedure was applied. The earlier results were, however, derived from data collected at sites that, for the most part, have quite similar geology and runoff regimes. In this paper we evaluate further the application of piecewise regression to data from channels with a wider range of geomorphic conditions. The results corroborate with those from the earlier work in that there is a relatively narrow range of discharges at which a substantial change in the nature of bedload transport occurs. The transition from primarily low rates of sand transport (phase I) to higher rates of sand and coarse gravel transport (phase II) occurs, on average, at about 80 per cent of the bankfull (1.5-year return interval) discharge. A comparison of grain sizes moved during the two phases showed that coarse gravel is rarely trapped in the samplers during phase I transport. Moreover, the movement and capture of the D-16 to D-25 grain size of the bed surface seems to correspond with the onset of phase II transport, particularly in systems with largely static channel surfaces. However, while there were many similarities in observed patterns of bedload transport at the 19 studied sites, each had its own 'bedload signal' in that the rate and size of materials transported largely reflected the nature of How and sediment particular to that system.

We examined the utility of three techniques (lacunarity, spectral, and wavelet analysis) for detecting scales of pattern of ecological data. We compared the information obtained using these methods for four datasets, including: surface temperature across space (linear transect), surface temperature across time, understory plant diversity across space (linear transect), and a simulated series of known structure. For temperature and plant diversity across the transect, we expected to find dominant scales of pattern of approximately 220 m and, for plant diversity scales of pattern of > 450 m, corresponding to management activities on the study landscapes. For temperature across time, we predicted a dominant scale of 24 h. The simulated data included a sine wave with a known period of 9.9 units, an edge at approximately 30 units, and a random component. The different analyses provided unique but complementary information. Lacunarity and spectral analyses were most consistent with each other across datasets, both indicating a dominant scale of pattern at 400-500 m (coarser than expected) for the transect temperature series, a lack of dominant scale in the pattern of understory diversity, and scales of pattern at 1.8-5.1 and 8.5-11.1 units ( wavelength) for the simulated data series. Spectral analysis best approximated an expected, 24 h period in the temporal temperature series. Wavelet variance detected finer scales of pattern (240 m) in transect temperature and suggested patterns in plant diversity at scales of 460 and 1100 m. By retaining locational information, only the wavelet transform and associated position variance detected the abrupt edge in the simulated data series. Wavelet analysis also emphasized variability, even within cyclic phenomena, not identified by spectral or lacunarity analyses, and suggested hierarchical structure in the pattern of understory plant diversity. The appropriate technique for assessing scales of pattern depends on the type of data available, the question being asked, and the detail of information desired. This comparison highlighted the importance of: (1) using multiple techniques to examine scales of pattern in ecological data; (2) interpreting analysis results in concert with examination and ecological knowledge of the original data; and (3) utilizing results to direct subsequent descriptive and experimental examination of features or processes inducing scales of pattern.

These procedures were evaulated for conditions in which heterogeneity and hidden bias were induced by confounding with missing variables associated with other improtant processes, a problem common in statistical modeling of ecological phenomena. Simulations for a large (N = 10000) finite population representing grid locations on a landscape demonstrated various forms of hidden bias that might occur when the effect of a measured habitat variable on some animal was confounded with the effect of another unmeasured variable. Quantile (0 <= tau <= 1) regression parameters for linear models that excluded the important, unmeasured variable revealed bias relative to parameters from the generating model. Depending on whether interactions of the measured and unmeasured variables were negative (interference interactions) or positive (facilitation interactions) in simulations without spatial structuring. either upper (tau > 0.5) or lower (tau < 0.5) quantile regression parameters were less biased than mean rate parameters. Heterogeneous, nonlinear response patterns Occurred with correlations between the measured and unmeasured variables. When the unmeasured variable was spatially structured. variation in parameters across quantiles associated with heterogeneous effects of the habitat variable was reduced by modeling the spatial trend surface as a cubic polynomial of location coordinates, but substantial hidden bias remained. Sampling (n = 20-300) simulations demonstrated that regression quantile estimates and confidence intervals constructed by invertin-weighted rank score tests provided valid coverage of these parameters. Local forms of quantile weighting were required for obtaining correct Type I error rates and confidence interval coverage. Quantile regression was used to estimate effects of physical habitat resources on a bivalve (Macomona liliana) in the spatially structured landscape on a sandflat in a New Zealand harbor. Confidence intervals around predicted 0.10 and 0.90 quantiles were used to estimate sampling intervals containing 80% of the variation in densities in relation to bed elevation. Spatially structured variation in bivalve counts estimated by a cubic polynomial trend surface remained after accounting for the nonlinear effects of bed elevation, indicating the existence of important spatially structured processes that were not adequately represented by the measured habitat variables.

This study reports the linkage between Wetland-DNDC and MIKE SHE for carbon dynamics and GHGs mitigation strategies analyses in forested wetland. Wetland-DNDC was modified by parameterizing forest management practices and refining anaerobic biogeochemical processes. Mortality due to senescence was estimated as a function of tree age or as a function of the relative biomass. We used a harvesting damage mortality coefficient as a linear function of time with three parameters: Initial mortality, Duration of the damage and Intensity of the initial harvesting. The model was validated against experimental data obtained from the GNF site near Florida. As a preliminary application, we simulated the effect of water table position and forest management practices on GHGs emissions and carbon dynamics to test the capabilities of the models for simulating seasonal and long-term carbon budget in forested wetland.

In the hippocampus, adult neurogenesis is affected both by aging and irradiation with ionizing particles. Likewise, the maturation of newly formed cells in this region as measured by PSA-NCAM expression is also altered by the aging process. The present study was designed to investigate the effects of 2.5 Gy of 1 GeV/n Fe-56 particles on neurogenesis using the nuclear proliferation marker 5-bromodeoxyuridine BrdU and PSA-NCAM expression in the dentate gyrus of rats exposed to whole-body irradiation or simply placed in the chamber without being irradiated. All subjects (n = 10) were sacrificed 28 days after the last BrdU injection (50 mg/kg X 3 days) and their brains were processed for immunohistochemistry. Results illustrate a decrease in the number of BrdU-positive cells as well as different distribution of these cells in the dentate gyrus of irradiated animals. Additionally, irradiated subjects show decreased levels of PSA-NCAM expression.

During the 1980s, Savannah River striped bass also suffered a population decline, when catch per unit effort (CPUE; #/hr) of large adults declined by 97% and egg production declined by 96%. Loss of freshwater spawning habitat through harbor modifications was identified as the primary cause. Population restoration began in 1990 and included stock enhancement and environmental remediation. Salinity levels in historic spawning and nursery habitats are now similar to those prior to the decline. Recently, egg production and CPUE of large striped bass both seem to be increasing. The increasing abundance of larger fish should result in continued increases in egg production, and eventually recruitment, and recent captures of wild-spawned larvae and juveniles confirm natural reproduction. However, current efforts to deepen the Savannah Harbor may preclude striped bass recovery by once again allowing saltwater intrusion into upper estuary spawning and nursery habitats. This case history may serve as another example of successful striped bass recovery efforts yet also underscores the need for continued monitoring and innovative research where populations are at risk or imperiled.

Two main generation peaks were found in June and September. Mean female body weight throughout the year was similar to those obtained in various crops in Indiana. In both studies, body weights were comparable to those found in laboratory experiments where females were fed 1 prey item every 3 to 9 days. Egg loads in Florida were similar to those found in field populations in Indiana. The increase in numbers of immature eggs later in the Florida season may be an indication of continued egg production in older females. We interpret this as possible evidence of synovigeny in the field. This result is consistent with previous laboratory data showing that immature eggs are continuously produced throughout female lifetime. Larger females predictably had higher mean egg loads. The similarity in biological characteristics found in field populations in Indiana and Florida suggest that the predator has similar impacts on pest species by low feeding rates.

In addition, the relationship between moth captures in black-light traps and larval densities in soybeans was examined. Parasitism was consistently high throughout the region averaging 80.3%, 82.3%, and 73.1% for all dates in 1995, 1996, and 1997, respectively, and appeared to suppress H. zea populations. The predominate parasite species was Microplitis croceipes (Cresson) with some parasitism by Cotesia marginiventris (Cresson), Meterous autographae Meusebeck, and Winthemia rufopicta (Bigot). The date of the peak weekly capture of moths explained 99.7% of subsequent larval densities in soybeans, while the average weekly moth catches did not. The earlier moth peak in 1995 corresponded with higher populations of larvae, while the later peaks in 1996 and 1997 were followed by very low, sub-economic larval populations. Departures from normal for precipitation and temperature during August explained 99.8% and 95.3%, respectively, of the variation in the date of peak moth capture.

The mymarid wasp, Gonatocerus tuberculifemur (Ogloblin), is an egg-parasitoid native to Argentina and its first known host is Tapajosa rubromarginata (Signoret), a species related to GWSS. Laboratory studies were made in Tucuman and Buenos Aires Provinces, Argentina. Seven generations were maintained in the laboratory, and only one adult emerged per host egg. The average parasitism rate was 71.6% of total eggs. Although eggs of all ages (4 to 190 h old) were parasitized, wasps did not emerge from eggs over 96 h old. The percentage of wasp emergence was 66.5% from eggs between 4 and 72 h old. Over the seven generations that G. tuberculifemur was reared, the parasitism rate ranged between 55-84%. This percentage of emergence increased as the parasitoid generations progressed. The duration of development from oviposition to adult emergence of G. tuberculifemur was 12.6 &PLUSMN; 1.8 days (range 11.4-13.0) at 22.5-27.5&DEG; C and 70-80% RH. The duration of development was significantly affected by sex and temperature. Males developed faster than females (12.2 vs. 12.8, respectively). The sex ratio was not significantly different from 1:1. Average adult longevity was 6.73 &PLUSMN; 3.93 days fed on honey. Male and female longevity was not significantly different.

Percent parasitism of D. abbreviatus eggs by C. etiennei decreased as eggs matured. The optimal age of C. etiennei for successful parasitism ranged from 1-2-d old. Host plant leaf thickness, leaf pubescence, and plant strata probably played a role on the parasitism by C. etiennei. This parasitoid is diurnal and spent approximately 5 min searching for eggs laid in cryptic locations, 46 min parasitizing an egg mass and 24 min resting. This biological information is relevant in evaluating the potential of C. etiennei in the classical biological control of D. abbreviatus. C1 USDA, APHIS, Miami, FL 33158 USA.

Tests were conducted in the Santa Maria valley, Guatemala during a sterile male release program. Traps were placed in or near host trees (primarily coffee and citrus) and in non-host trees when no hosts were available. Trap locations were grouped according to elevation every 170 m. Elevation group midpoints were 1103, 1273, 1443, and 1613 m above sea level. The spatial distributions of sterile males, wild males, and females were clumped throughout the 13 wk of sampling. More wild female flies were captured in coffee in the 1273 m elevation and on non-host trees in the 1103 m elevation. The number of wild males was directly related to the number of wild females captured, and the sex ratio (female: male) was highest at the 1443 and 1613 m elevation ranges. There was no relationship between the number of sterile males and number of wild females in the traps at any elevation. At all elevation ranges, an inverse relationship was observed between the numbers of wild females and males with the mean numbers of sterile males per trap. Wild C. capitata populations appeared to decrease when 40 sterile males were captured per trap with wild females per week. The results indicated that, during the sampling period evaluated, coffee appeared to be the main host plant for the wild population, C. capitata were more abundant at the 1273 m elevation range than at other elevations. Additional or alternative host species may harbor the female population at other times. C1 USDA, ARS, Subtrop Hort Res Stn, Miami, FL 33158 USA.

We performed a 2-year study at a number of organic farms in Alachua County, Florida to determine if the presence of sunflower rows included in a polyculture system increased the occurrence and abundance of beneficial insects in cropped fields. The occurrence of beneficial insects was significantly greater on sunflower than on crop vegetation in control blocks and crop vegetation greater than 10 m distant from sunflowers. While crop vegetation 10 m distant from sunflowers harbored significantly fewer beneficial insects, this difference in occurrence was not seen in crop vegetation 1 m distant from sunflowers. Our results indicate that sunflowers indeed attract and play host to numerous beneficial insects suggesting that sunflower plantings within rows of vegetable crops may indeed be an effective way to attract beneficial insects into cropped fields. However, further study is required to fully describe the distances key beneficial insects move from sunflowers and the impact these beneficial insects have on crop pests.

Recently, we characterized the innate immune response phenotype of parental lines of broilers ( A and B) and F1 reciprocal crosses ( C and D). In vitro heterophil functional analyses and in vivo challenge trials showed line A was more immunologically responsive and more resistant to Salmonella ( Gram- negative bacteria) and Eimeria tenella ( parasitic protozoan) infections than line B. Further, cross D was more responsive with increased resistance compared to cross C. We hypothesized that line A and D chickens were also more resistant to gram- positive bacteria. Day- old chickens were challenged with vancomycin- resistant Enterococcus gallinarum ( VREG), euthanized, and hearts, livers, and spleens cultured for VREG. One- day post challenge, there were significantly fewer VREG- positive hearts, livers, and spleens in line A than line B. Likewise, cross D chickens had significantly fewer VREG- positive hearts, livers, and spleens than cross C chickens. To determine if VREG was cleared, chickens were necropsied seven days post- challenge. Again, significantly fewer organ cultures from line A and D were VREG- positive compared to line B and C. Further, this study showed the hematologic profile reflected changes associated with protection against VREG; there were significantly more circulating heterophils and monocytes in VREG- resistant lines A and D with no changes in VREG- susceptible lines B and C. Collectively, line A and D chickens are immunologically more responsive and more resistant to pathogens, including VREG, compared to line B and C chickens. C1 ARS, USDA, College Stn, TX 77845 USA.

ABE (98.97 gL(-1)) were produced from lactose (227 gL(-1)) at a yield of 0.44 and productivity of 0.21 gL(-1)h(-1). It should be noted that the ratio of acids to solvents was significantly lower in the perstraction experiment compared to the control batch process suggesting that acids were converted to solvents. The perstraction experiment results are superior to the control batch fermentation where 9.34 gL(-1) ABE was produced. It was determined that lactose at 250 gL(-1) was a strong inhibitor to the cell growth of C acetobutylicum and fermentation. A membrane with an area of 0.1130 m 2 was used as the perstraction membrane while oleyl alcohol as the perstraction solvent. Removal of ABE by perstraction was faster than their production in the reactor, and the maximum concentration of ABE in the oleyl alcohol was 9.75 gL(-1). It is viewed that recovery of ABE from oleyl alcohol (at this concentration) would be more economical than recovery from the fermentation broth. It is suggested that a new membrane be developed which can offer a higher ABE flux. Alternately, silicalite membranes that were successfully developed for pervaporation could be used for perstraction. Using such an integrated system would reduce process streams and save significant processing costs.

Nutrim-5 is one of a family of beta-glucan-containing hydrocolloids that is prepared by thermo-shear processing of oat flour or bran. The rheological properties of the noodle flour composites indicated that Nutrim-5 contributed binding qualities to the composites. Nutrim-5 appeared to contribute functionality to the rice flour, allowing for larger quantities to be used in the making of Asian noodles. The noodles were prepared in 20 kg batches by mixing blends of wheat flour, rice flour, and Nutrim-5 with alkali, salt solution, and egg. After mixing and kneading into smooth sheets, the noodles were cut, curled, and deep fat-fried. By using 10% by weight Nutrim-5 in the formulation, it was possible to satisfactorily make noodles using 50% rice flour. The cooking loss and tensile strength were measured and found to be satisfactory for this amount of rice flour in the noodles. A trained sensory panel also indicated that these noodles did not reveal any difference in taste. Published by Elsevier Ltd.

Six treatments and two blank incubations were conducted, testing whole mature raw seed as substrates on an equal protein basis. Considering cholestyramine as 100% bound, the relative in vitro bile acid binding for kidney bean, black gram, bengal gram and moth bean on equal protein basis was 12%, 15%, 35% and 13%, respectively. Relative bile acid binding on equal dry matter (DM), total dietary fiber (TDF) and insoluble dietary fiber (IDF) basis was for kidney bean 3%, 11% and 14%, black gram 3%, 29% and 36%, bengal gram 7%, 27% and 29%, and moth bean 3%, 19% and 21%, respectively. Except for bengal gram where values were much higher, bile acid binding by kidney bean, black gram and moth bean appear to be related to their DM and protein content. These results point to bile acid binding by bengal gram > black gram = moth beans = kidney bean as indicative of their health-promoting potential. Data suggest that of all four kinds of beans tested, bile acid binding may be related to the anionic, cationic, physical and chemical structure, composition, metabolites, or their interaction with active binding sites. Animal studies are in progress to validate relationship of in vitro bile acid binding of various beans observed herein to lipid, cholesterol-lowering and atherosclerosis amelioration.

Aggregate cohorts of humans consisted of (1) "control" groups of consumers, (2) groups of swine workers, and (3) groups of slaughter-plant workers. Analyses of cross-sectional AR data from 472 human and 376 swine isolates are presented. AR phenotypes among these isolates were compared by (1) host species, (2) facility location, (3) facility type, (4) housing (human) or production (swine) cohort, and (5) sample collection period and time of day. There were significant (p < 0.05) differences in isolates among host-species with swine uniformly at greater risk for (1) AR to four specific antimicrobials (kanamycin, streptomycin, sulfamethoxazole, tetracycline), and (2) multiple resistance phenotypes (p < 0.0001). Facility type and unit location were more often associated with AR differences among swine isolates than among human isolates. Swine production group was significantly associated with AR prevalence (p < 0.05) for nine antimicrobials; in general, purchased boars, suckling piglets, weaned piglets, and lactating sows were at higher risk of AR. There was no significant (p > 0.05) association of human occupational/consumer cohort with AR prevalence. Several unique AR phenotypes were detected in each of the human- and swine-intake groups. These data establish baseline characteristics for an on-going 3-year longitudinal study designed to further characterize AR phenotype and genotype in this population. Host-, facility-, and cohort-specific data demonstrate that sufficient prevalence differences exist to permit the future quantification of AR transmission, should it occur. Based on these cross-sectional data, occupational exposure to either swine-rearing or swine-slaughter facilities does not appear to be associated with the prevalence of phenotypic resistance among the commensal fecal E. coli isolated from this integrated system.

The goal of this study was to evaluate those factors related to holding that increased the prevalence of S. enterica in swine at slaughter. To accomplish this goal, we focused on holding time and flooring. Our objectives were to (1) compare Salmonella enterica prevalence among pigs held for short (15-45 min) versus long (up to 4 h) periods before slaughter; and (2) determine the impact of flooring (slatted vs. concrete) as it relates to the prevalence of S. enterica. The study consisted of seven repetitions at a large volume (11,000 head/day) Midwest abattoir. Each repetition consisted of one truck load of pigs (n = 170) sorted into one of three groups: (1) animals held for a short time (15-45 min) on solid floors (short-hold); (2) animals held for 4 +/- 0.5 h on slatted floors; and (3) animals held for 4 0.5 h on solid concrete floors. At slaughter, samples were collected from 30 pigs in each group. Cecal contents (20 mL), feces (20 g), and the ileocecal lymph node were cultured for S. enterica. Additionally, the effect of holding time on meat quality parameters (loin pH at 35 min and 6 h, color, drip loss) was evaluated for the first four replicates. The proportion of S. enterica-positive samples was highest (p < 0.05) in the cecum of pigs held on solid concrete floors (72.4%), and slightly less for pigs held on slatted floors (63.3%). Animals held for less than 45 min before slaughter demonstrated the lowest proportion of S. enterica-positive samples (52.9%). The pig prevalence, as measured by any one of the three samples being positive, was significantly different (p < 0.05) between animals held on solid floors (81%) and those animals held for 45 min or less before slaughter (69%). Meat quality, as measured by multiple parameters, was adversely affected by lack of a rest period. The mean 24-h pH was significantly lower for the short-hold group compared to the other two groups. The mean Minolta L and the drip loss were significantly higher in the short-hold group. From this and other studies, it appears that elimination of the holding process is not feasible S. enterica control option, given current U.S. harvesting systems.

The primary source of transmission to humans is suggested as mishandled raw poultry or consuming improperly prepared chicken. The focus of this report was to characterize the prevalence and cell numbers of the organism within the commercial Icelandic poultry industry. Commercial broiler flocks were sampled from May 2001 through 2003 in a total population study. At the slaughter plant, 40 randomly selected ceca were obtained from each flock, pooled into four samples containing 10 ceca each, and analyzed. Cell numbers and prevalence of Campylobacter spp. were estimated by direct plating of dilutions onto Campy-Cefex agar and incubating the plates at 42 C under microaerobic atmosphere; colonies were confirmed as Campylobacter spp. by microscopy and latex agglutination to provide quantification of cell numbers per gm of cecal material. A total of 15.4% of the flocks carried the organism at at a maximum cell number of 8.1 x 10(7) cfu/g, having a mean raw count of colonized birds at 1.3 x 10(7) cfu/g (geometric mean of 1.5 x 10(6)). During the 3 years of sampling, the prevalence ranged from 17.6% to 17.3% to 12.7% for slaughter years 2001, 2002, and 2003, respectively. Isolation rates varied with numbers of catch lots (groups of birds taken for slaughter)/flock; with one catch lot/flock, the prevalence was 13.7%, with two 17.5%, and with three 33.3%. With increased flock size, isolation rates also increased; flocks of greater than 5,000 birds had a prevalence of 12.0% positive, 14.0% of flocks with 5,000-10,000 birds were positive, and 25.5% of flocks with more than 10,000 birds were positive for Campylobacter spp. Isolation rates varied with the processing lines: M was positive at 17.3%, B was positive at 10.1%, and G at 17.2%. Flocks were more frequently colonized in the warmer months, and younger birds were less frequently colonized than were older slaughtered birds.

In the round and tapered form, timbers are not susceptible to the strength-reducing effects of diving grain and exposed juvenile wood. Fiber continuity around knots on the surface of a debarked log rarely exhibits the stress concentration and fracture propagation commonly seen in disrupted grain around knots in lumber. Symmetry of material properties about the centroidal axis in a round timber improves the efficacy of standard section property equations derived for uniform isotropic materials. Ignoring these benefits and comparing the strength of round and processed timbers solely on the basis of section property, the round section has from two to four times the bending load design capacity of any standard-sized processed timber that could be sawn from it.

The objectives were to determine if the basic wood quality had changed due to service, to develop a notion of probable design values that could be expected for timbers sawn from reclaimed Douglas-fir utility poles, and to assess the relationship between design properties obtained from small, clear specimens and full-size visually graded timbers. Pressure-treated Douglas-fir utility poles retired from service were sampled. The sample poles were cut to 7.6 m (25 ft.) long, and then the poles were crosscut to produce two subsamples, each 3.8 m (12.5 ft.) long. Each subsample was sawn into a 150- by 150-mm (6- by 6-in.) timber, and these were visually graded as Posts and Timbers. The timbers were destructively tested to assess bending strength and modulus of elasticity. At the same time, limited testing of small, clear specimens was conducted on a different sample of poles. The small, clear properties data showed that the wood quality of the poles was similar to published values. Both the design values derived from small, clear specimens and the full-size tests showed that Posts and Timbers with heart center can meet the published design values for No. 1. It was also shown that visual inspection is an effective method of separating poles that will produce timbers that meet the visual grade requirements for structural products.

Longitudinal stress waves were used to evaluate peeler cores from 111 Douglas-fir stems. Supplementary dynamic and static tests were then conducted on 2 by 4 lumber sawn from the cores. Stress wave testing of peeler cores was found to be a good predictor of static and dynamic modulus of elasticity (MOE) of lumber sawn from the cores. However, correlations between stress wave MOE of the peeler cores and bending and tensile strength of derived standard-size lumber were low. Nonetheless, based on past experience, the data derived could establish a means for classifying peeler cores into three stress classes, which would have higher levels of confidence for assigned bending and tensile design strength. For lumber stress wave MOE compared with peeler core stress wave MOE, the coefficient of determination (r(2)) value was 0.81. In the comparison of transverse vibration MOE of lumber with stress wave MOE, peeler cores had a corresponding r(2) of 0.72. Comparison of statically determined tensile MOE of the lumber with stress wave MOE of the cores showed an r(2) of 0.70, but for ultimate tensile strength of the lumber taken as one large group compared with stress wave MOE, the r(2) was only 0.38. For statically determined modulus of rupture of the derived lumber taken as a single group compared with dynamic stress wave MOE of the peeler cores, the r(2) was 0.32.

Hawkes in the VIR (Russian) and US Potato Genebanks SO GENETIC RESOURCES AND CROP EVOLUTION LA English DT Article DE Genebank; Globodera rostochiensis; nematode; potato; Solanum tuberosum L. subsp andigena AB Cultivated Solanum tuberosum L. subsp. andigena is well known as a rich source of valuable traits for potato breeding, especially for resistance to diseases and pests. The golden potato cyst nematode, Globodera rostochiensis Woll., is considered to be one of todays most serious hindrances to potato production in Europe and North America. Thus, the breeding of new cultivars that have resistance to PCN is of great importance. The USPG (USA) and VIR (Russian) potato genebanks, as well as others, maintain many samples of primitive cultivated and wild potato species originating from Latin America. Many of these samples are assumed to be genetically duplicated because the material in both genebanks came from the same original source. A joint investigation of new genotypes of subsp. andigena forms resistant to potato cyst nematode (PCN) was carried out on samples of subsp. andigena at VIR with reputed duplicate samples at USPG. After careful screening, 14 samples which possessed resistance to PCN were identified. A high level of this resistance was transmitted to sexual progeny at a high frequency for all of the selections. Eleven of the accessions found to be resistant have reputed duplicates in USPG that were not previously known to be resistant. Thus, this research not only broadens the choice of parents available for resistance breeding, but identifies model materials for future research to test the parity of PCN resistance among reputed duplicate samples in the two genebanks.

SO GENETICS LA English DT Article ID MULTILOCUS GENOTYPE DATA; POPULATION-STRUCTURE; CULTIVATED RICE; MICROSATELLITE MARKERS; MAIZE; DNA; DOMESTICATION; ASSOCIATIONS; POLYMORPHISM; EVOLUTION AB The population structure of domesticated species is influenced by the natural history of the populations of predomesticated ancestors, as well as by the breeding system and complexity of the breeding practices exercised by humans. Within Oryza saliva, there is an ancient and well-established divergence between the two major subspecies, indica and japonica, but finer levels of genetic structure are suggested by the breeding history. In this study, a sample of 234 accessions of rice was genotyped at 169 nuclear SSRs and two chloroplast loci. The data were analyzed to resolve the genetic structure and to interpret the evolutionary relationships between groups. Five distinct groups were detected, corresponding to indica, aus, aromatic, temperate japonica, and tropical japonica rices. Nuclear and chloroplast data support a closer evolutionary relationship between the indica and the aus and among the tropical japonica, temperate japonica, and aromatic groups. Group differences can be explained through contrasting demographic histories. With the availability of rice genome sequence, coupled with a large collection of publicly available genetic resources, it is of interest to develop a population-based framework for the molecular analysis of diversity in O. sativa.

Heritabilities averaged 0.56 for three body weights, 0.23 for two energy balance characters, 0.48 for three bone characters, 0.35 for four measures of adiposity, and 0.27 for three organ weights, all of which were generally consistent in magnitude with estimates derived in previous studies. Genetic correlations varied from - 0.65 to + 0.98, and were higher within these functional groups than between groups. These correlations generally conformed to a priori expectations, being positive in sign for energy expenditure and consumption (+ 0.24) and negative in sign for energy expenditure and adiposity (- 0.17). The genetic correlations of adiposity with body weight at 3, 6, and 12 weeks of age (- 0.29, - 0.22, - 0.26) all were negative in sign but not statistically significant. The independence of body weight and adiposity suggests that this advanced intercross population is ideal for a comprehensive discovery of genes controlling regulation of mammalian adiposity that are distinct from those for body weight.

We assessed the effects of biological factors on F-ff by comparing a maturing pine plantation (PP) and a nearby mature Oak-Hickory-type hardwood forest (HW). F-ff was measured continuously with soil chambers connected to an IRGA during 2001-2002. At both sites, F-ff depended on soil temperature at 5 cm (T-5) when soil was moist (soil moisture, theta > 0.20 m(3) m(-3)), and on both T-5 and theta when soil was drier. A model (F-ff (T-5, theta)) explained >= 92% of the variation in the daily mean F-ff at both sites. Higher radiation reaching the ground during the leafless period, and a thinner litter layer because of faster decomposition, probably caused higher soil temperature at HW compared with PP. The annual F-ff was estimated at 1330 and 1464 g C m(-2) yr(-1) for a year with mild drought (2001) at PP and HW, respectively, and 1231 and 1557 g C m(-2) yr(-1) for a year with severe drought (2002). In the wetter year, higher soil temperature and moisture at HW compared with PP compensated for the negative effect on F-ff of the response to these variables resulting in similar annual F-ff at both stands. In the drier year, however, the response to soil temperature and moisture was more similar at the two stands causing the difference in the state variables to impel a higher F-ff at HW. A simple mass balance indicated that in the wetter year, C in the litter-soil system was at steady state at HW, and was accruing at PP. However, HW was probably losing C from the mineral soil during the severe drought year of 2002, while PP was accumulating C at a lower rate because of a loss of C from the litter layer. Such contrasting behavior of two forest types in close proximity might frustrate attempts to estimate regional carbon (C) fluxes and net C exchange.

We explore spatial and temporal patterns of breeding and recruitment by eastern spadefoot toads (Scaphiopus holbrookii), using nine years of data from continuous monitoring with drift fences and pitfall traps at eight ephemeral ponds in longleaf pine-wiregrass sandhills. Breeding events ( greater than or equal to25 adults at a pond within a month) occurred 23 times on nine occasions at seven of the eight study ponds, but substantial recruitment (greater than or equal to100 metamorphs) followed only five events. Recruitment ranged from 0-4648 among ponds. Only four ponds functioned as population "sources", and only during some years. The other ponds, and even "source" ponds during some years, functioned either as "sinks," where breeding occurred with no resulting recruitment, or were not used at all for breeding. Most recruitment occurred during four years. Recruitment was correlated with adult breeding effort, but only during some years. Recaptures were rare, and inter-pond exchange of adults was minimal and short-distance (<130 m; one was 416 m). Most (83.5%) individuals captured were metamorphs, and 15.9% were greater than or equal to51 mm (est. greater than or equal to4 yr). We conservatively estimated a 7-vr lifespan. Adult "population" trends clearly reflected breeding effort rather than numbers per se; capture rates fluctuated dramatically among years, but showed no overall trends during the 9-yr study. Our paper is provides empirical information that can be used to generate realistic metapopulation models for S. holbrookii as a tool in conservation planning.

The case of the Nerorongoro Conservation Area, Tanzania SO HUMAN ORGANIZATION LA English DT Article DE ecotourism; sustainable development; Maasai; Ngorongoro ID MAASAI AB This paper examines what is needed to transform nature tourism to protected areas into ecotourism, having genuine social benefits and serving as a tool for sustainable community development. It draws on the case of the Ngorongoro Conservation Area, Tanzania's most visited protected area, and a multiple land use zone inhabited by the pastoral Maasai peoples. I argue that for ecotourism to promote sustainable development in communities that are its supposed beneficiaries, three fundamental conditions must be met. First, opportunities to capture the economic benefits of tourism must be structured in a way that is culturally appropriate, and therefore accessible to the target population. Second, for communities to benefit from ecotourism, they need secure land tenure over the area in which it takes place, as well as the ability to make land use decisions for that area. Third. tourism benefits to local communities must be more than economic; they must promote deeper social and political justice goals that, if left unaddressed, restrict peoples' ability to enjoy the economic benefits of tourism. Without these elements, the conservation outcomes of ecotourism are likely to be less favorable. C1 US Forest Serv, USDA, Pacific NW Res Stn, Portland, OR 97208 USA.

The CAs play an important role in insect physiology because of their production of the juvenile hormones (JHs), i.e., key hormones involved in development and reproduction. We found that the P bioculatus CA-CC complex is present in two distinct morphological forms, the more frequently observed eomplex containing one "fused" CA between two CCs and the more rarely observed complex having one CA laterally attached to each CC. These complexes were tested for their ability to synthesize JH-like compounds. We found that the primary lipophilic compound synthesized by the CA-CCs migrated differently from JH III (a JH found in numerous insect species) when subjected to thin-layer chromatography. Furthermore, the synthesis of this compound is stimulated by 2E,6E-farnesol, a known precursor for JH III. These data indicate that the P bioculatus CACC product has chemical properties similar to that of other (as of yet unidentified) hemipteran JHs. In addition, we found that the synthesis of this product is sensitive to pH and buffer type; minimally or not affected by the absence of the CC; expressed at similar levels in days 5-30 postemergent adults; and inhibited or decreased in adults reared under low temperature-short day conditions.

However, little is known regarding cuphea's optimal mineral nutritional requirements or responses to inhibiting elements. Oil seed crops often need additional phosphorus (P) to achieve optimal economic yield. Vanadium (V), a commonly occurring soil constituent, interferes with plant P uptake and earlier work showed that V is a factor in lipid metabolism. Hydroponic culture was used to evaluate the relative effect of V on the development of cuphea. Relative root length, root surface area, root weight, and aerial dry weights decreased exponentially as the V concentration increased from 0 to 153 mu M. In contrast to field observations of other crops, additions of MgSO4 to increase the Mg:(Mg + Ca) ratio further decreased plant growth by as much 50% at V concentrations greater than 31 mu M. Root length was decreased by about 50% of the control when the plant was grown in 153 mu M V and relative root area and dry weight were decreased by >= 75%. Increases in V concentration sharply reduced secondary and higher order lateral branching. Reduction in root growth was accompanied by a general chlorotic appearance. The results suggest that readily available V in field situations will result in poor root growth and crop performance. Also, the interaction of V and MgSO4, common in soils in the region, will lead to further reductions in yields in the field. Published by Elsevier B.V.

The isolation and purification of these hydrolysis products are of particular interest both for their potential use in organic synthesis and for their biological activities.

The procedures use solvent extraction of autolyzed defatted seedmeals from various plant sources together with variable reaction pHs and solvent partitioning to obtain relatively pure (generally > 97%) compounds without the need for chromatographic separation.

To identify specific parasite antigens inducing bovine CTL and helper T-lymphocyte responses for vaccine development against bovine neosporosis, the tachyzoite major surface proteins NcSAG1 and NcSRS2 were targeted. In whole tachyzoite antigen-expanded bovine T-lymphocyte lines, recombinant NcSRS2 induced potent memory CD4(+)- and CD8(+)-T-lymphocyte activation, as indicated by proliferation and gamma interferon (IFN-T) secretion, while recombinant NcSAG1 induced a minimal memory response. Subsequently, T-lymphocyte epitope-bearing peptides of NcSRS2 were mapped by using overlapping peptides covering the entire NcSRS2 sequence. Four experimentally infected cattle with six different major histocompatibility complex (MHC) class II haplotypes were the source of immune cells used to identify NcSRS2 peptides presented by Holstein MHC haplotypes. NcSRS2 peptides were mapped by using IFN-gamma secretion by rNcSRS2-stimulated, short-term T-lymphocyte cell lines, IFN-gamma enzyme-linked immunospot (ELISPOT) assay with peripheral blood mononuclear cells, and 5Cr release cytotoxicity assay of rNcSRS2-stimulated effector cells. Four N. caninum-infected Holstein cattle developed NcSRS2 peptide-specific T lymphocytes detected ex vivo in peripheral blood by IFN-gamma ELISPOT and in vitro by measuring T-lymphocyte IFN-gamma production and cytotoxicity. An immunodominant region of NcSRS2 spanning amino acids 133 to 155 was recognized by CD4(+) T lymphocytes from the four cattle. These findings support investigation of subunit N. caninum vaccines incorporating NcSRS2 gene sequences or peptides for induction of NcSRS2 peptide-specific CTL and IFN-gamma secreting T lymphocytes in cattle with varied MHC genotypes.

Azoles were variably effective against mold fungi that are frequently found on wood and wood products. Unseasoned southern yellow pine specimens that were dip-treated with varying concentrations of eight azoles were evaluated for their ability to resist mold infestation when challenged with Aspergillus niger, Penicillium chrysogenum, and Trichoderma viride spores. Minimal fungicidal concentrations (MFC90) were determined to be 0.016% for thiabendazole and 0.043% for voriconazole, the most efficacious azoles against the challenge fungi. We conclude that thiabendazole or voriconazole may be used alone or in combination to inhibit mold fungi on unseasoned pine. (C) 2004 Elsevier Ltd. All rights reserved.

Results of a survey of mites from the Carl Hayden AZ lab and from cooperators in five locations (Arizona, California, Florida, Maine, North Dakota) showed that some mites were susceptible to all three acaricides (Amitraz, Coumaphos, Fluvalinate) in the spring of 2003, but by fall most mites were resistant. Mites were resistant to all chemicals, even from beekeepers that do not treat colonies with acaricides. We used esterase native activity gets to test for the presence of specific esterases which might be involved in pesticide resistance in varroa. All mites tested had positive bands for esterase, even those exhibiting susceptibility to some acaricides. Based on the differences between the esterase activity gel profile of the susceptible and cross-resistant V destructor, it is possible that an esterase-mediated resistance mechanism is operative in the population of the mites we analyzed. However, a combination of other resistance mechanisms may be present which make the esterase activity gel method unreliable for use in identifying varroa mites with multiple resistance.

For this purpose six subjects consumed 500 ml PEF-treated vegetable soup/day, and six subjects consumed 500 ml FM vegetable soup/day for 14 days. On the first day of the study, the subjects drank the vegetable soup in one dose (dose-response study), and on days 2-14 they consumed 250 ml in the morning and 250 ml in the afternoon (multiple-dose-response study). Blood was collected every hour for 6 h on the first day and again on days 7 and 14. All blood samples were analyzed for vitamin C, 8-epiPGF(2 alpha), and uric acid. The maximum increase in plasma vitamin C occurred 3 h post-dose in both the PEF and the FM groups. Vitamin C remained significantly higher (P <= 0.05) on days 7 and 14. The plasma 8-epiPGF(2 alpha) concentration was significantly lower at the end of the study in both the PEF group (P = 0.002) and the FM group (P = 0.05). Plasma levels of vitamin C and 8-epiPGF(2 alpha) were inversely correlated in both groups (r = -0.549, P = 0.018; and r = -0.743, P = 0.0004, respectively). To summarize, drinking two servings (500 ml) of PEF-treated or FM gazpacho daily increases plasma vitamin C and significantly decreases 8-epiPGF(2 alpha) concentrations in healthy humans.

(type strain NRRL Y-7556(T) = CBS 2612(T)) is described. Of the four known strains of this species, two were isolated from black oak trees in California, USA, one from an Emory oak in Arizona, USA, and one from an unidentified source in Mexico. The species forms hat-shaped ascospores in deliquescent asci and appears to be homothallic. Analysis of nucleotide sequences from domains D1/D2 of large-subunit (26S) rDNA separates the new species from Komagataella pastoris, the type species of the genus, and from Pichia pseudopastoris, which is here renamed Komagataella pseudopastoris (Dlauchy, Tornai-Lehoczki, Fulop T Peter) Kurtzman comb. nov.

University of Illinois has developed a modified dry grind process that allows for recovery of the germ and pericarp fractions prior to fermentation. The process could potentially generate an additional 5-7 cents of income per gallon ethanol produced from enhanced fermentation efficiency and from recovering the corn oil. This process also allows for the possibility of converting the fractionated pericarp, termed "quick fiber," to ethanol. This review summarizes results reported earlier (1) on the feasibility of using Quick Fiber (QF) as an ethanol feedstock. QF was converted to ethanol using an industrial Saccharomyces cerevisiae strain and ethanologenic Escherichia coli strain FBR5. For the S. cerevisiae fermentation, the ethanol yield was 0.096 gal/bu of processed corn assuming a QF yield of 3.04 lb/bu. For the bacterial fermentation, the final ethanol concentration was 30 g/l or 85% of the theoretical yield. The residuals from the fermentations were also evaluated as a source of corn fiber oil. Corn fiber oil, which is extracted from the pericarp fiber fraction, is a nutraceutical being developed by the ARS that has cholesterol lowering properties. Corn fiber oil yields were 1.12% w/w for the residual material from the SSF process. For the FBR5 fermentations, the residual fiber was recovered after hydrolysis and prior to fermentation. The corn fiber oil yield in this case was 8.28% w/w. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Peoria, IL 61604 USA. Natl Renewable Energy Lab, Biotechnol Div Fuels & Chem, Golden, CO 80401 USA.

Design - Case-control study. Procedure - Questionnaires were used to collect information out farm characteristics, biosecurity rneasures, and husbandry practices on 151 infected premises (128 turkey and 23 chicken farms) and 199 noninfected premises (167 turkey and 32 chicken farms). Results - The most significant risk factor for AI infection was disposal of dead birds by rendering (odds ratio [OR] 73). In addition, age greater than or equal to 10 weeks (OR for birds aged 10 to 19 weeks, 4.9; OR for birds aged greater than or equal to 20 weeks, 4.3) was a significant risk factor regardless of poultry species involved. Other significant risk factors included use of nonfamily caretakers and the presence of mammalian wildlife on the farm. Factors that were not significantly associated with infection included use of various routine biosecurity measures, food and litter sources, types of domestic animals on the premises, and presence of wild birds on the premises. Conclusions and Clinical Relevance - Results suggest that an important factor contributing to rapid early spread of AI virus infection among commercial poultry farms during this outbreak was disposal of dead birds via rendering off-farm. Because of the highly infectious nature of AI virus and the devastating economic impact of outbreaks, poultry farmers should consider carcass disposal techniques that do not require farm movement, such as burial, composting, or incineration.

This study examined the health records of 45,497 calves over a 20-yr period to determine environmental and genetic factors influencing the incidence of IBK. Three data sets were analyzed with an animal model. The first data set (n = 41,986) evaluated environmental factors and genetic differences among nine purebred (Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental) and three composite breeds (MARC I, MARC II, and MARC III). Weaning weights of calves diagnosed with IBK were 8.9 kg lighter (P < 0.05) than weights of healthy calves. Incidence of IBK was related to age of the calf and the seasonal life cycle of the face fly (Musca autumnalis). Incidence of IBK increased in the spring (June), peaked during the summer months (July to September), and then decreased in the fall. Herefords were the most susceptible breed (P < 0.05) compared with all other purebreds and composites. Estimates of direct heritability for the incidence of IBK were generally low and ranged from 0.00 to 0.28 by breed. The maternal permanent environmental and genetic effects of the dam on the incidence of IBK were not significant for most breeds. The second data set (n = 9,606) was used to estimate heterosis for the incidence of IBK from a Hereford and Angus diallel design. The heterosis effect for the incidence of IBK in reciprocal Hereford/Angus crossbred calves was slightly negative (P = 0.12) but not large. The higher incidence of TBK in Angus x Hereford calves compared with Hereford x Angus calves (13.3 vs. 8.9%) suggests a maternal effect related to the incidence of TBK. Incidence of IBK in crossbred calves sired by tropically adapted breeds (Brahma, Boran, Tuli) compared with purebred and crossbred Bos taurus types was investigated in the third data set (n = 2,622). Crossbred calves sired by tropically adapted breeds had a lower incidence of IBK than most Bos taurus types (P < 0.05), but they were not different than either reciprocal crosses of Hereford and Angus or purebred Angus calves. Response to selection for decreasing the incidence of IBK is likely to be slow because of low heritability and low incidence in most breeds. Significant breed differences for incidence of IBK may be important to some producers and management systems. C1 USDA ARS, Meat Anim Res Ctr, Clay Ctr, NE 68933 USA.

In general, estimates of genetic parameters that would be needed for national genetic evaluation were similar to previous estimates for Columbia, Rambouillet, and Targhee sheep, although estimates of direct heritability for Polypay were somewhat less for birth weight, slightly greater for weaning weight, significantly greater for fleece weight, and the same for number born as for those three breeds. For birth weight only, evidence was found for important dam x year or dam x number born interactions, which are essentially litter effects, as was found for the other dual-purpose breeds. There were 11,896, 11,104, 7,748, and 7,831 records for birth and weaning weights, fleece weight, and number born per litter, with 255 to 316 sires of animals with records.

Pigs were allotted to four treatments including: 1) nonchallenged control (NONC); 2) challenged control (CHAC); 3) 7% (as-fed basis) spray-dried plasma (SDP); and 4) 2% (as-fed basis) glutamine (GLN). On d 11 after weaning, all pigs were fitted with an indwelling jugular catheter. On d 12 after weaning, pigs in the CHAC, SDP, and GLN groups were orally challenged with skim milk E. colt K88(+) culture, whereas pigs in the NONC group were orally inoculated with sterilized skim milk. Rectal temperatures and fecal diarrheic scores were recorded and blood samples collected at 0 (baseline), 6, 12, 24, 36, and 48 h after the challenge for serum hormone and cytokine measurements. At 48 h postchallenge, all pigs were killed for evaluation of small intestinal morphology. There was no effect of feeding SDP or GLN on growth performance during the 11-d prechallenge period (P = 0.13). At 48 h after the challenge, CHAC pigs had decreased ADG (P = 0.08) and GY (P = 0.07) compared with the NONC pigs; however, SDP and NONC pigs did not differ in GY, and GLN and NONC pigs did not differ for ADG and GY. At 6, 36, and 48 h after the challenge, CHAC, SDP, and GLN pigs had increased rectal temperature relative to the baseline (P = 0.09). At 12 and 36 h after the challenge, CHAC pigs had the highest incidence of diarrhea among treatments (P = 0.08). Serum IL-6 and ACTH were not affected by treatment or time after E. coli challenge (P = 0.11). In proximal, midjejunum, and ileum, CHAC pigs had greater villous atrophy and intestinal morphology disruption than NONC pigs (P < 0.01), whereas SDP and GLN pigs had mitigated villous atrophy and intestinal morphology impairment after E. coli challenge. Pigs in the SDP had the lowest GH at 12 h and the greatest GH at 36 h after the challenge among treatments (P = 0.08). Pigs in the NONC had the highest IGF-1 at 12 and 36 h postchallenge (P < 0.04). These results indicate that feeding glutamine has beneficial effects in alleviating growth depression of E. coli K88(+)-challenged pigs, mainly via maintaining intestinal morphology and function, and/or possibly via modulating the somatotrophic axis.

Consumers evaluated each steak for overall like, tenderness, juiciness, flavor like, and flavor amount using 10-point scales (I = dislike extremely, not at all tender, not at all juicy, dislike extremely, and none at all to 10 like extremely, extremely tender, extremely juicy, like extremely, and an extreme amount of flavor, respectively). Quality grade affected several consumer sensory traits, with top Choice receiving higher (P <= 0.004) tenderness, juiciness, and flavor like scores than high Select. Consumers in Chicago rated steaks cooked "medium and less" higher for overall like, tenderness, juiciness, flavor like, and flavor amount than those in Philadelphia (city x degree of doneness; P <= 0.020). Steaks braised by customers in Philadelphia received among the highest scores for overall like, tenderness, juiciness, flavor like, and flavor amount compared with any cooking method used by customers in Chicago (cooking method x city; P <= 0.026). Overall like and flavor amount ratings were least (P < 0.05) for steaks that were marinated and cooked to "medium and less" degree of doneness (marination x degree of doneness; P <= 0.014). Braised steaks received among the highest values for overall like, tenderness, juiciness, flavor like, and flavor amount when cooked to "medium and less" or "medium well and more" (cooking method x degree of doneness; P <= 0.008). Correlation and stepwise regression analysis indicated that flavor like was pivotal in customers' satisfaction with top round steaks, and was the sensory trait most highly correlated to overall like, followed by tenderness, flavor amount, and juiciness. Preparation of top round steaks was crucial in consumers' likes and dislikes, and by improving flavor, higher consumer satisfaction may be achieved.

The concentration and ruminal degradability of CP in beef cattle diets may affect urinary and fecal excretion of N and thus may affect ammonia emissions from beef cattle feed yards. To determine the effects of dietary CP concentration and degradability on potential ammonia emissions, 54 steers were randomly assigned to nine dietary treatments in a 3 x 3 factorial arrangement of treatments. Treatments consisted of three dietary CP concentrations (11.5, 13, and 14.5%) and three supplemental urea:cottonseed meal ratios (100:0, 50:50, and 0:100 of supplemental N). Steers were confined to tie stalls, and feces and urine excreted were collected and frozen after approximately 30, 75, and 120 d on feed. One percent of daily urine and feces excretion were added to polyethylene chambers containing 1,550 g of soil. Chambers were sealed, and ammonia emissions were trapped in an acid solution for 7 d using a vacuum system. As the protein concentration in the diet increased from 11.5 to 13%, in vitro daily ammonia emissions increased (P < 0.01) 60 to 200%, due primarily to increased urinary N excretion. As days on feed increased, in vitro ammonia emissions also increased (P < 0.01). Potential ammonia losses were highly correlated (P < 0.01) to urinary N (r(2) = 0.69), urinary urea-N (r(2) = 0.58) excretion, serum urea-N concentration (r(2) = 0.52), and intake of degradable protein N (r(2) = 0.23). Although dietary composition can affect daily ammonia losses, daily ammonia emissions must be balanced with effects on animal performance to determine optimal protein concentrations and forms in the diet.

The test uses Bacillus megaterium ATCC 9885 as the indicator organism and Mueller Hinton agar as the growth medium. Compared to Swab Test on Premises (STOP), developed in 1970, this screening test has higher sensitivity and the ability to detect a wider range of veterinary antimicrobial residual drugs, particularly sulfonamides, at lower concentrations. Carcasses that are tested with CAST and suspected of containing chemical residue above tolerance level are retained for confirmation. Disposition of these carcasses are determined upon laboratory result. Routine testing of bob veal calves with CAST allowed the Food Safety and Inspection Service to release most calf carcasses within 24 h post-slaughter, thus conserving shipping and handling resources. However, changes in the regulation in 1990 dictate that disposition of carcasses found to contain violative levels of sulfonamide residues should be based on laboratory findings. The analysis of the data for the years 1990-1994 and 1998 indicate that the use of CAST over the years was significant, and had a direct impact on reduction of residue violations in veal carcasses. With the use of CAST, potentially harmful antimicrobial chemicals entering the human food chain through veal meat have been minimized.

This microbial inhibition test detects antimicrobials that are allowed to be used in food animals. It has the ability to detect these antimicrobials at or above the allowable limit in carcass kidney fluids in 6 h. Laboratory evaluations show that the lower limit of detection (LLD) of FAST and the Calf Antibiotic and Sulfa Test (CAST) for antibiotics tested was the same, but the LLD for sulfonamides of FAST was lower than the LLD of CAST. Compared with the Swab Test on Premises (STOP) developed in 1977, the LLD's of FAST for both antibiotics and sulfonamides were significantly better. Under field conditions, the sensitivity of FAST and CAST to antibiotic and sulfonamide residues in animal kidneys was not significantly different, but the time required by FAST was significantly lower than CAST (6 versus 18 h). Compared with the STOP, the sensitivity and the range of detection by FAST for all antimicrobials were significantly higher and the testing time was lower (18 versus 6 h).

The method is known as the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticide residues in foods. The procedure involved the extraction of a 15 g sample with 15 mL acetonitrile, followed by a liquid-liquid partitioning step performed by adding 6 g anhydrous MgS04 plus 1.5 g NaCl. After centrifugation, the extract was decanted into a tube containing 300 mg primary secondary amine (PSA) sorbent plus 1.8 g anhydrous MgS04, which constituted a cleanup procedure called dispersive solid-phase extraction (dispersive SPE). After a second shaking and centrifugation step, the acetonitrile extract was transferred to autosampler vials for concurrent analysis by gas chromatography/mass spectrometry with an ion trap instrument and liquid chromatography/tandem mass spectrometry with a triple quadrupole instrument using electrospray ionization. Each analytical method was designed to analyze 144 pesticides, with 59 targeted by both instruments. Recoveries for all but 11 of the analytes in at least one of the matrixes were between 70-120% (90-110% for 206 pesticides), and repeatabilities typically < 10% were achieved for a wide range of fortified pesticides, including methamidophos, spinosad, imidacloprid, and imazalil. Dispersive SPE with PSA retained carboxylic acids (e.g., daminozide), and < 50% recoveries were obtained for asulam, pyridate, dicofol, thiram, and chlorothalonil. Many actual samples and proficiency test samples were analyzed by the method, and the results compared favorably with those from traditional methods.

The method, known as the quick, easy, cheap, effective, rugged, and safe (QuEChER method for pesticide residues in foods, now involves the extraction of the sample with acetonitrile (MeCN) containing 1% acetic acid (HAc) and simultaneous liquid-liquid partitioning formed by adding anhydrous MgSO4 plus sodium acetate (NaAc). The extraction method is carried out by shaking a centrifuge tube which contains 1 mL of 1% HAc in MeCN plus 0.4 g anhydrous MgSO4 and 0.1 g anhydrous NaAc per g sample. The tube is then centrifuged, and a portion of the extract is transferred to a tube containing 50 mg primary secondary amine sorbent plus 150 mg anhydrous MgSO4/mL of extract. After a mixing and centrifugation step, the extract is transferred to autosampler vials for concurrent analysis by gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/tandem mass spectrometry. Independent of the original sample pH, the use of buffering during the extraction yields pH < 4 in the MeCN extract and > 5 in the water phase, which increases recoveries of both acid- and base-sensitive pesticides. The method was evaluated for 32 diverse pesticides in different matrixes, and typical percent recoveries were 95 10, even for some problematic pesticides. Optional solvent exchange to toluene prior to GUMS analysis was also evaluated, showing equally good results with the benefit of lower detection limits, but at the cost of more time, material, labor, and expense.

One method, dubbed the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticide residue analysis, entailed extraction of 15 g sample with 15 mL acetonitrile (MeCN) containing 1% acetic acid followed by addition of 6 g anhydrous magnesium sulfate and 1.5 g sodium acetate. After centrifugation, 1 mL of the buffered MeCN extract underwent a cleanup step (in a technique known as dispersive solid-phase extraction) using 50 mg each of C-18 and primary secondary amine sorbents Plus 150 Mg MgSO4. The second method incorporated a form of matrix solid-phase dispersion (MSPD), in which 0.5 g sample plus 2 g C-18 and 2 g anhydrous sodium sulfate was mixed in a mortar and pestle and added above a 2 g Florisil column on a vacuum manifold. Then, 5 x 2 mL MeCN was used to elute the pesticide analytes from the sample into a collection tube, and the extract was concentrated to 0.5 mL by evaporation. Extracts in both methods were analyzed concurrently by gas chromatography/mass spectrometry and liquid chromatography/tandem mass spectrometry. The recoveries of semi-polar and polar pesticides were typically 100% in both methods (except that basic pesticides, such as thiabendazole and imazalil, were not recovered in the MSPD method), but recovery of nonpolar pesticides decreased as fat content of the sample increased. This trend was more pronounced in the QuEChERS method, in which case the most lipophilic analyte tested, hexachlorobenzene, gave 27 1% recovery (n = 6) in avocado (15% fat) with a < 10 ng/g limit of quantitation.

Recent suppression trials using mass trapping with a synthetic food-based bait, initiated in alternate host crops before the start of persimmon season, had shown promise as a means of reducing C. capitata population levels. However, this did not adequately suppress C. capitata population where there were adjacent plantings of coffee, Coffea arabica L., a favoured alternate host, which bears fruits before and during the persimmon season. To improve C. capitata population suppression, we applied a spinosad-based bait spray to coffee plants, starting before persimmon fruits became susceptible to oviposition by the Mediterranean fruit fly. The bait spray suppressed the C. capitata population and led to reduced infestation of both coffee cherries and persimmon fruits. Percentage parasitization of C. capitata in coffee cherries by established biological control agents, primarily Fopius arisanus (Sonan), was not significantly different in unsprayed vs. sprayed plots even after 11 weekly sprays. These results suggest that mass trapping, combined with spinosad-based bait sprays, are control components that are compatible with biological control and can be combined in an integrated pest management system for C. capitata.

There is disagreement about amino acid feeding regimens for broilers, particularly When raising heavy broilers for maximum carcass and breast meat yields. Two experiments evaluated the effect of feeding a nutritional program similar to that currently used by the US poultry industry (low amino acid density; LD) and an isocaloric program with higher amino acid levels (high amino acid density; HD) on the performance of broilers varying in sex and strain gross (I high-yield strain and 2 multipurpose strains). Data from both experiments were pooled because no interactions between trials were noted. Broilers fed HD diets had increased BW and decreased feed conversion (g of feed/g of gain) throughout all phases of the study when compared with broilers fed LD diets. Males, had higher BW and lower feed conversion than females. Mortality was unaffected by diet type, strain, or sex. Broilers of the high-yield strain had lower BW and higher feed conversions when compared with the 2 multipurpose strains. Broilers fed HD diets resulted in lower abdominal fat percentage, as well as higher fillet and tender yields at 42 and 56 d of age. No effect of dietary regimen was observed for yield of carcass, wings, drums, or saddle. Carcasses from female broilers typically had higher percentages of fat and wings and lower drum and saddle yields. The high-yield strain had higher percentages of fillets, tenders and carcass and lower fat and saddle yields when compared with the multipurpose strains. Overall improvements in economically important parameters (i.e., feed conversion, and white meat yield) observed after feeding an amino acid concentration greater than that typically used by some broiler integrators in the US suggest that industry standard nutritional programs may be low in amino acids. Considerations for increasing current amino acid concentrations should be made on a cost-benefit basis. C1 Mississippi State Univ, Dept Poultry Sci, Mississippi State, MS 39762 USA.

The technique involved (after scalding, defeathering, and head removal) separating (breaking) the neck from the carcass parallel with the shoulders and leaving the ventral neck skin, trachea, and esophagus intact. With an individual carcass suspended by its wings from a shackle, the esophagus was grasped above the proventriculuis within the thoracic cavity, and the crop was pulled-through the thoracic inlet. The maximum load required to remove the crop from the carcass was recorded, and it was determined if the crops removed were intact or ruptured. Carcasses that had the neck broken prior to crop removal had significantly more crops removed intact (85%, 35 of 40) for both rooster and lien carcasses compared with only 20% removed intact (8 of 40 carcasses) for rooster and hen carcasses in which the neck remained unbroken. The load required to remove the crop was influenced by gender and treatment. Rooster carcasses required a higher load (5.7 kg) than hen carcasses (4.9 kg), and for rooster carcasses, breaking the neck prior to evisceration resulted in a lower load (5.2 kg) to remove the crop than that of carcasses in which the neck remained unbroken (6.2 kg). The difference (0.2 kg) in the load recorded for crops removed intact and those that ruptured was not significant and suggests that crops ruptured during removal resulted from external attachments and not to inherent weakness. Breaking the neck of broiler breeder carcasses prior to evisceration improved the efficiency of intact crop removal (85% removed intact) and would thereby minimize the incidence of crop contents contaminating the carcass during evisceration.

The present study was, conducted to determine if several foodborne, pathogens (Campylobacter, Salmonella, and Clostridium perfringens) could be isolated from the ductus deferens, testes, and ceca of 45- to 65-wk-old commercial broiler breeder roosters. Five roosters from each of 3 separate, commercial housed breeder farms were transported to the laboratory. An aseptic necropsy was performed to remove the ductus deferens, testes, and ceca without surface contamination from blood and other tissues. All samples were analyzed for each of the 3 previously mentioned bacteria, total aerobic bacteria, and Enterobacteriaceae. None of the 3 foodborne pathogens were isolated from the testes of the 15 commercial, roosters. Clostridium perfiringens was isolated from 1 of the 15 ductus deferens, whereas no Campylobacter or Salmonella were isolated from this tissue. Campylobacter was cultured from the ceca of all 15 roosters, Clostridium perfringens from 14/15, and Salmonella from 2/15. One-quarter of all commercial broiler breeder's semen samples were found, to be contaminated with Campylobacter in a previous study; however, this organism as well as Salmonella and Clostridium perfringens were not found in the reproductive tissues located in the abdominal region. Escherichia coli and Enterococcus faecium were occasionally cultured from the ductus deferens. These data suggest that the contamination of semen by these foodborne pathogens is via fecal or cecal contamination as the semen passes through the cloaca and not from bacterial colonization of the testes and ductus deferens.

Mesquite shrubs were removed from nine plots, six plots were grazed by yearling cattle in August and six plots were grazed in February for the last 3 years of the 5 year study. Arthropod species richness ranged between 154 and 353 on grasses, from 120 to 266 on G. sarothrae, and from 69 to 116 on P. glandulosa. There was a significant relationship between the number of families of insects on grass and G. sarothrae and growing season rainfall but species richness was not a function of growing season rainfall on any of the plants. Several of the arthropod families that were the most species rich in this grassland were found on all of the plants sampled, i.e. Salticid spiders, Bruchid and Curculionid beetles, Cicadellid and Psyllid homopterans, and ants (Formicidae). There were more species rich families that were shared by grasses and the sub-shrub G. sarothrae than with mesquite. The absence of a relationship between growing season rainfall and species richness was attributed to variation in life history characteristics of arthropods and to the non-linear responses of annual and perennial desert grassland plants to rainfall. There were no significant differences in insect family or species richness on any of the plant types as a result of removal of mesquite (P. glandulosa) from selected plots. Intense, short duration (24 h) grazing by livestock during in late summer resulted in reduced species richness in the grass-herb vegetation layer but had no effect on insect species richness on snakeweed or mesquite shrubs. Livestock grazing in winter had no effect on insect species richness on any of the vegetation sampled. (C) 2004 Elsevier Ltd. All rights reserved.

Location The study was conducted on contiguous ranches (one actively grazed by cattle, one that had not been grazed since 1968) in the Sonoita Valley of southern Arizona. Plant communities on both ranches were comprised of Chihuahuan semi-desert grassland, savanna, and Madrean evergreen woodland ecosystems, but large areas were dominated by Lehmann and Boer lovegrass, African grass species that were introduced more than 50 years ago. Methods We selected 243 individuals that had been defoliated and bark scorched during the fire using a stratified random design based on pre-fire grazing status and dominant grass cover. After the start of the 2003 growing season, we recorded individual tree characteristics, fire damage, and measures of post-fire response, and tested for relationships among classes of: grazing status, bark damage, dominant grass cover type, abundance of live and dead aboveground branches, flowering status, and sprout number and size. Analyses of fire damage and post-fire response were interpreted with respect to values of fireline intensity, scorch height and energy release that were projected by a fire behaviour model, nexus. Results Nearly all of the trees on grazed areas suffered low levels of fire damage, while a majority on ungrazed areas suffered moderate to severe damage. Trees on grazed areas consequently had significantly more leaf-bearing twigs and branches in 2003 but a very low number of root sprouts, while individuals on ungrazed areas had a greater density of root sprouts but little post-fire dead branching and almost no living branches. Among the ungrazed grassland types, more than 75% of the trees on Boer lovegrass plots suffered moderate to severe damage, while a similar percentage of trees in native grass areas suffered low damage. These differences were: (1) attributed to variations in fire characteristics that were caused by differences in litter production and removal, and (2) ecologically significant because trees in the severe damage class showed almost no aboveground post-fire branching, either live or dead in 2003, while trees in the low damage class exhibited a greater amount of both. Main conclusions Our results affirm the notion that effective management of western grasslands where mesquite encroachment has or will become a problem requires a better understanding of how interactions among key ecosystem influences (e.g. fire, grazing, non-native species) affect not only mesquite seedlings and saplings but also larger, established individuals and thereby the long-term structure and functioning of semi-desert grassland ecosystems. As managers shift their focus from eradication to management of mesquite in western grasslands and savannas, our results provide insights into how prescribed fires (and their effects on mesquite populations) differ from wildfires and how such effects may be mediated by the altered land uses and ecosystem characteristics that now exist in many western ecosystems.

Zucker obese rats ( a model of the early stages of type 2 diabetes) and Zucker diabetic fatty rats ( a model for type 2 diabetes) after supplementation ( 1,000 mu g Cr/kg) have lower fasting plasma total, high-density lipoprotein, and LDL cholesterol, triglycerides, glycated hemoglobin, and insulin levels and lower 2-h plasma insulin levels in glucose tolerance tests. The lowering of plasma insulin concentrations with little effect on glucose concentrations suggests that the supplement increases insulin sensitivity. The cation after 12 and 22 or 24 weeks of administration lowers ( P< 0.05) fasting plasma glycated hemoglobin levels in the Zucker diabetic and Zucker obese rats, respectively, and thus can improve the glucose status of the diabetic models. The effects cannot be attributed to the propionate ligand. C1 Univ Alabama, Dept Chem & Coalit Biomol Prod, Tuscaloosa, AL 35487 USA.

However, the nature of these interactions leading to induced plant volatile emissions during pathogen infection is unclear. We previously demonstrated that a complex volatile blend including (E)-beta-ocimene, methyl salicylate (MeSA), and numerous sesquiterpenes was released by tobacco plants, Nicotiana tabacum K326, infected with an avirulent/incompatible strain of Pseudomonas syringae pv. tomato (Pst DC3000). In contrast, a volatile blend, mainly consisting of MeSA and two unidentified sesquiterpenes, was released by plants infected with P. syringae pv. tabaci (Pstb) in a virulent/compatible interaction. In this study, we examined the interaction of multiple pathogen stresses, phytohormone signaling, and induced volatile emissions in tobacco. Combined pathogen infection involved the inoculation of one leaf with Pst DC 3000 and of a second leaf, from the same plant, with Pstb. Combined infection reduced emissions of ocimene and MeSA compared to plants infected with Pst DC 3000 alone, but with no significant changes in total sesquiterpene emissions. In the compatible interaction, Pstb elicited a large ethylene burst with a peak emission occurring 3 days after inoculation. In contrast, the incompatible interaction involving Pst DC3000 displayed no such ethylene induction. Pstb-induced ethylene production was not significantly altered by Pst DC3000 in the combined infection. We postulated that Pstb-induced ethylene production may play a regulatory role in altering the typical volatile emission in tobacco in response to Pst DC3000 infection. To clarify the role of ethylene, we dynamically applied ethylene to the headspace of tobacco plants following infection with Pst DC3000. Consistent with Pstb-induced ethylene, exogenous ethylene reduced both ocimene and MeSA emissions, and selectively altered the ratios and amounts of induced sesquiterpene emissions. Our findings suggest that ethylene can regulate the magnitude and blend of induced volatile emissions during pathogen infection. C1 Univ Florida, Dept Entomol & Nematol, Gainesville, FL 32611 USA.

We tested hydroquinone as a phagostimulant using workers from three colonies of the Formosan Subterranean termite, Coptotermes formosanus, under both laboratory and field conditions. Hydroquinone at concentrations ranging from ca. 0.002-20.0 ng/cm(2) did not increase visitation by C. formosanus workers to treated over control filter papers, and was actually repellent at a 20 ng/cm2 dose. No phagostimulant response to hydroquinone was observed in two colonies. In the third, there was a significant increase in feeding on filter paper treated with a 2 ng/cm2 dose, but was significantly lower at a 20 ng/cm(2) dose. Furthermore, sand treated with a gradient of hydroquinone, did not evoke increased tunneling activity compared with controls. GC-MS analysis of C. formosanus workers indicated that hydroquinone was present at an average of 41 pg/worker. It was also determined that within one week about 11% hydroquinone in aqueous solution oxidized to 1,4-benzoquinone. Our findings indicate that hydroquinone alone does not act as a phagostimulant but instead may act as a repellent at higher concentrations. The attractant/arrestant of the Formosan termite may have multiple components of which hydroquinone, at low doses, could be one.

We evaluated (1) the response of four Pinus species to fungal invasion and (2) the effects of plant secondary metabolites on primary growth of and secondary colonization of three consistent fungal associates. Two of these fungi, Entomocorticium sp. A and Ophiostoma ranaculosum, are obligate mutualists with D.frontalis, and the third associate is a blue-staining fungus, O. minus, that is commonly introduced by beetles and phoretic mites. O. minus negatively affects beetle larvae and in high abundance can impact D. frontalis population dynamics. Size of lesions formed and quantity of secondary metabolites produced in response to fungal inoculations varied significantly among Pinus species. However, monoterpene composition within infected tissue did not significantly vary across treatments. While all eight tested metabolites negatively affected the growth rate of O. minus, only 4-allylanisole, p-cymene, and terpinene reduced the growth of the mycangial fungi. Surprisingly, growth rates of mycangial fungi increased in the presence of several secondary metabolite volatiles. O. minus out-competed both mycangial fungi, but the presence of secondary metabolites altered the outcome slightly. O. ranaculosunt out-performed E. sp. A in the presence of dominant conifer monoterpenes, such as alpha- and beta-pinene. Volatiles from the mycangial fungi, particularly E. sp. A, had a negative effect on O. minus growth. In general, phloem phytochemistry of particular Pinus species appeared to alter the relative growth and competitiveness of mutualistic and non-mutualistic fungi associated with D.frontalis. The outcome of interactions among these fungi likely has important consequences for the population dynamics of D. frontalis. C1 Dartmouth Coll, Dept Biol Sci, Hanover, NH 03755 USA.

In field experiments in Australia, synthetic Z6Z9-11-one-21Hy as a single component attracted male moths. Wind tunnel experiments suggested that a 4-component blend consisting of Z6Z9-11-one-21Hy, (6Z,9R,10S)-cis-9, 10-epoxy-heneicosene (Z6-9R 10S-epo-21Hy), (E,E)-7,9-heneicosadien-6,11-dione (E7E9-6,11-dione-21Hy), and 6-hydroxy-(E,E)-7,9-heneicosadien-11-one (E7E9-6-ol-11-one-21Hy) (all present in pheromone gland extracts) might induce more males to orient toward, approach, and contact the source than did Z6Z9-11-one-21Hy as a single component. Additional experiments are needed to determine conclusively whether or not Z6-9R 10S-epo-21Hy, E7E9-6, 11-dione-21Hy, and E7E9-6-ol-11-one-21Hy might be minor sex pheromone components of PAM. Moreover, attractiveness of synthetic pheromone and virgin PAM females needs to be compared to determine whether synthetic pheromone could replace PAM females as trap baits in the pro-ram to monitor eradication of exotic PAM in New Zealand.

Gas chromatographic (GC) analysis of volatiles collected from feeding male or female beetles, or saltcedar foliage alone, showed two components produced almost exclusively by males. These compounds elicited responses from antennae of male and female beetles in GC-electroantennographic detection (EAD) analyses. The compounds were identified as (2E,4Z)-2,4-heptadienal (1) and (2E,4Z)-2,4-heptadien-1-ol (2) by GC-mass spectrometry (MS), and confirmed with authentic standards. The two compounds were also detected at trace levels from feeding females and foliage controls, but the amounts from feeding males were 8-40 times higher, typically 55-125 ng per day per male. The amounts of 1 and 2 in collections from females did not differ significantly from amounts collected from control foliage. In field trials, 2 as a single component was as attractive as a 1: 1 blend of 1 and 2. Compound 1 as a single component was more attractive than controls, but much less attractive than 2 or the blend. Males and females were attracted in about equal numbers, indicating that this is an aggregation pheromone. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Crop Bioprotect Res Unit, Peoria, IL 61604 USA.

Procedures for several aBMD scans of clinical interest might be limited by artifact, inaccessible anatomical regions, and positioning errors. Sites for scanning that overcome these limitations need further investigation for application to large-scale screening and relevance to clinical decisions regarding diagnosis and treatment. In this study, 146 women (mean SE age = 20.1 +/- 0.1 yr, height = 163.3 +/- 0.2 cm, weight = 60.0 +/- 0.2 kg) underwent DXA of the total body (TB) and right and left total proximal femurs (TPF), total forearms (TF), and distal tibiae (DT). Osteopenia was identified in 24 women. Areal BMD was positively related among all measurement sites (r = 0.55-0.81, all p < 0.001). Total body, TF, and DT aBMD each displayed low sensitivity (0.29-0.33) and high specificity (0.95-0.98) to detect osteopenia of the TPF. Addition of TB fat-free mass slightly enhanced the predictive value of DT aBMD. Overall, DT aBMD can discriminate between osteopenic and normal subjects with comparable accuracy to TB or TF aBMD.

This included investigation of factors influencing DD, summarizing variation in herd means as well as within-herd variation, and estimation of parameters related to DD. Data consisted of records initiated before 2003 from cows first calving after 1996. A total of 459,075 records from 295,067 cows in 3527 herds were included. The overall mean DD was 60.5 d, and standard deviation among herd means was 5.8 d. Approximately 91% of all herds had mean DD between 50 and 70 d. There were 41 herds that had mean DD of less than or equal to45 d and 2 herds with mean DD of less than or equal to30 d. Some herds (125) had unusually long mean DD (exceeding 71 d). Variation across regions of the United States was minimal, although southwestern herds did show somewhat longer DD than other regions. Days open (DO) accounted for the most variation in DD with longer DO leading to longer dry periods. Heritability of DD was 7% and repeatability 12%. Error correlations indicated that longer dry periods benefit both milk yield and somatic cell score in the subsequent lactation. Genetic and permanent environmental correlations were large, which indicated that 1) bias would result if genetic evaluations for milk yield included an adjustment for DD, and 2) correction for cow effects is warranted in estimation of DD effects on performance. The relationship between DD and DO is due primarily to permanent cow effects. Improved fertility will enhance the feasibility of shortened dry periods.

Three types of health traits were targeted. First, available infectious conditions were used to identify animals that are superior in their general immunity (including innate immunity) for infectious diseases. Generalized immunity may be thought of as a combination of immune responses to a variety of immune system challenges. Second, single infectious and noninfectious diseases were analyzed separately. Third, infectious reproductive diseases as one category of related conditions, and cystic ovary disease as one category of 3 related noninfectious ovary disorders were studied. Data were analyzed using a threshold model that included herd, calving year, season of calving, and parity as cross-classified fixed factors; and sire and cow within sires as random effects. Days at risk and days in milk at the beginning of a record were included by fitting the days as continuous covariates in the model. A heritability value of 0.202 +/- 0.083 was estimated for generalized immunity. Heritability values of 0.141 and 0.161 were estimated for uterine infection and mastitis, respectively. Heritability of single noninfectious disorders ranged from 0.087 to 0.349. The amount of additive genetic variance recovered in the underlying scale of noninfectious disorders tended to zero when combining multiple conditions. The study supports combining infectious diseases into categories of interest but we do not recommend the same approach for noninfectious disorders. C1 Cooperat Resources Int, Shawano, WI 54166 USA.

The upkeep of these facilities requires continual maintenance and occasional remodeling. The superintendents and architects responsible for the maintenance and remodeling efforts need non-destructive tools for obtaining information on shallow subsurface features within parts of the golf course, particularly tees and greens. The subsurface features of importance include, but are not limited to, constructed soil layer characteristics and drainage system infrastructure. Near-surface geophysical methods can potentially provide a non-destructive means for golf course superintendents and architects to obtain the shallow subsurface information required to address their maintenance and remodeling concerns. This case study assessment of near-surface geophysical methods in regard to golf course applications focused on electromagnetic induction (EMI) and ground penetrating radar (GPR) techniques. The investigation employed two different EMI ground conductivity meters. Two GPR systems were also tested including the evaluation of antenna center frequencies ranging from 250 to 1,000 MHz. The study incorporated three separate sites. Measurements with both EMI and GPR were collected on a tee and a green at the Muirfield Village Golf Club in Dublin, Ohio, U.S.A. and on a practice green at the Golf Club of Dublin in Dublin, Ohio, U.S.A. GPR was also tested on a golf course green at the Guelph Turfgrass Institute T Environmental Research Centre in Guelph, Ontario, Canada. Results indicate that use of the appropriate EMI equipment can provide information on spatial changes of shallow apparent electrical conductivity (ECa) within golf course green constructed soil layers. This ECa data could potentially be employed to gauge constructed soil layer conditions, including wetness, salinity, etc., within different areas of a green. GPR proved quite capable of obtaining useful information on the golf course tee and greens that were studied, at least in regard to constructed soil layer thicknesses/depths or their areal extent and in locating the subsurface drainage pipe systems present. For the GPR center antenna frequencies evaluated, ranging from 250 to 1,000 MHz, all seemed to work relatively well for mapping tee and green constructed soil layer areal extent and drainage pipe locations. The higher frequency 900 and 1,000 MHz antennas appeared to work best for resolving thicknesses/depths of constructed soil layers within the tee and greens investigated. In addition, computer modeling of synthetic GPR profiles provide valuable insight and help considerably with data interpretation. While more research is certainly warranted, near-surface geophysical methods, especially EMI and GPR, appear to show promise with respect to acquiring the data needed in golf course maintenance and remodeling applications.

Four types of cause were studied: illegal behavior, carelessness, economic and population growth, and natural events. Identical environmental losses (e.g., of a herd of elk or a large stand of trees) were considered most serious when caused by illegal behavior or carelessness, and only slightly less serious when caused by growth. Losses due to these three types of human causes were considered much more serious than when the same losses were caused by natural events. Naturally caused environmental losses were probably considered least serious because they do not provoke the sense of violation or responsibility commonly associated with human-caused losses, and because naturally caused losses are often considered unavoidable and in the natural scheme of things.

Emissions can be reduced by covering slurry stores, but this can incur significant costs, as well as practical and technical difficulties. In this pilot-scale study, slurry was stored in small tanks (500 L) and the effectiveness of natural crust development for reducing NH3 emissions was assessed in a series of experiments. Also, factors important in crust development were investigated. Measurements were made of crust thickness and specially adapted tank lids were used to measure NH3 emissions. Slurry dry matter (DM) content was the most important factor influencing crust formation, with no crust formation on slurries with a DM content of < 1%. Generally, crusts began to form within the first 10 to 20 d of storage, at which time NH3 emission rates would decrease. The formation of a natural crust reduced NH3 emissions by approximately 50%. The type of bedding used in the free stall barn did not influence crust formation, nor did ambient temperature or air-flow rate across the slurry surface. There was a large difference in crust formation between slurries from cattle fed a corn (Zea mays L.) silage-based diet and those fed a grass silage-based diet, although dietary differences were confounded with bedding differences. The inclusion of a corn starch and glucose additive promoted crust formation and reduced NH3 emission. The maintenance of a manageable crust on cattle slurry stores is recommended as a costeffective means of abating NH3 emissions from this phase of slurry management.

Experimental and modeling studies were undertaken to examine the roles of attachment, detachment, and straining on oocyst transport and retention. Saturated column studies were conducted using Ottawa aquifer sands (U.S. Silica, Ottawa, IL) with median grain sizes of 710,360, and 150 mu m. Decreasing the median sand size tended to produce lower effluent concentrations, greater oocyst retention in the sand near the column inlet, and breakthrough of oocysts at later times. Oocyst transport data also exhibited concentration tailing. Mathematical modeling of the oocyst transport data using fitted first-order attachment and detachment coefficients provided a satisfactory description of the observed effluent concentration curves, but a poor characterization of the oocyst spatial distribution. Modeling of these data using an irreversible straining term that is depth dependent provided a better description of the oocyst spatial distribution, but could not account for the observed effluent concentration tailing or late breakthrough times. A more physically realistic description of the data was obtained by modeling attachment, detachment, and straining. The percentage of total oocysts retained by straining was estimated from effluent mass balance considerations to be 68% for 710-mu m sand, 79% for 360-mu m sand, and 87% for 150-mu m sand. Straining coefficients were then selected to achieve these percentages of total oocyst retention, and attachment and detachment coefficients were fitted to the effluent concentration curves. Dramatic differences in the predicted oocyst breakthrough curves were observed at greater transport distances for the various model formulations (inclusion or exclusion of straining). Justification for oocyst straining was provided by trends in the transport data, simulation results, pore size distribution information, and published literature.

This study investigated the characteristics and spatial distribution of total chlordane and its three most abundant compounds, including alpha-chlordane, gamma-chlordane, and trans-nonachlor, in sediments from the Cedar and Ortega rivers, Florida, USA, using geographic information system (GIS)based kriging analyses and field measurements. Kriging analysis showed that two areas, one from the Cedar River area and the other from the northern end of the Ortega River area, were contaminated. The maximum concentrations of total chlordane gamma-chlordane, alpha-chlordane, and trans-nonachlor in the sediments were, respectively, 101.8, 20.1, 26.3, and 19.2 mu g/kg. A plot of total organic carbon (TOC)-normalized chlordane concentrations showed that effects of grain size on sediment chlordane contamination were negligible. A principal axis analysis further revealed that a linear correlation existed between alpha-chlordane and total chlordane as well as between gamma-chlordane and total chlordane, whereas no correlation existed between trans-nonachlor and total chlordane. Comparison of total chlordane concentration with Florida Sediment Assessment Guidelines showed that the Cedar River and the northern end of the Ortega River had total chlordane concentrations above the probable effect level (4.79 mu g/kg), which could pose a potential risk to aquatic lire.

Computer modeling can help identify agricultural areas with high potential P transport. Most models use a constant extraction coefficient (i.e., the slope of the linear regression between filterable reactive phosphorus [FRP] in runoff and soil P) to predict dissolved P release from soil to runoff, yet it is unclear how variations in soil properties, management practices, or hydrology affect extraction coefficients. We investigated published data from 17 studies that determined extraction coefficients using Mehlich-3 or Bray-1 soil P (mg kg(-1)), water-extractable soil P (mg kg(-1)), or soil P sorption saturation (%) as determined by ammonium oxalate extraction. Studies represented 31 soils with a variety of management conditions. Extraction coefficients from Mehlich-3 or Bray-1 soil P were not significantly different for 26 of 31 soils, with values ranging from 1.2 to 3.0. Extraction coefficients from water-extractable soil P were not significantly different for 17 of 20 soils, with values ranging from 6.0 to 18.3. The relationship between soil P sorption saturation and runoff FRP (mu g L-1) was the same for all 10 soils investigated, exhibiting a split-line relationship where runoff FRP rapidly increased at P sorption saturation values greater than 12.5%. Overall, a single extraction coefficient (2.0 for Mehlich-3 P data, 11.2 for water-extractable P data, and a split-line relationship for P sorption saturation data) could be used in water quality models to approximate dissolved P release from soil to runoff for the majority of soil, hydrologic, or management conditions. A test for soil P sorption saturation may provide the most universal approximation, but only for noncalcareous soils.

Impacts on greenhouse gases, odor compounds, nitrogen losses, and dust SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID BIOCHEMICAL-ORIGINS; IN-VITRO; EMISSIONS; ACCUMULATION; AMMONIA; SURFACE; WASTE AB Beef cattle feedlots face serious environmental challenges associated with manure management, including greenhouse gas, odor, NH3, and dust emissions. Conditions affecting emissions are poorly characterized, but likely relate to the variability of feedlot surface moisture and manure contents, which affect microbial processes. Odor compounds, greenhouse gases, nitrogen losses, and dust potential were monitored at six moisture contents (0.11, 0.25, 0.43, 0.67, 1.00, and 1.50 g H2O g(-1) dry matter [DM]) in three artificial feedlot soil mixtures containing 50, 250, and 750 g manure kg(-1) total (manure + soil) DM over a two-week period. Moisture addition produced three microbial metabolisms: inactive, aerobic, and fermentative at low, moderate, and high moisture, respectively. Manure content acted to modulate the effect of moisture and enhanced some microbial processes. Greenhouse gas (CO2, N2O, and CH4) emissions were dynamic at moderate to high moisture. Malodorous volatile fatty acid (VFA) compounds did not accumulate in any treatments, but their persistence and volatility varied depending on pH and aerobic metabolism. Starch was the dominant substrate fueling both aerobic and fermentative metabolism. Nitrogen losses were observed in all metabolically active treatments; however, there was evidence for limited microbial nitrogen uptake. Finally, potential dust production was observed below defined moisture thresholds, which were related to manure content of the soil. Managing feedlot surface moisture within a narrow moisture range (0.2-0.4 g H2O g(-1) DM) and minimizing the accumulation of manure produced the optimum conditions that minimized the environmental impact from cattle feedlot production.

Impact on Escherichia coli O157 SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID BOVINE MANURE; DAIRY FARMS; CONTAMINATED MANURE; IRRIGATION WATER; PERSISTENCE; PREVALENCE; FECES; OUTBREAK; SURVIVAL; TRANSMISSION AB The moisture and manure contents of soils at cattle feedlot surfaces vary spatiotemporally and likely are important factors in the persistence of Escherichia coli O157 in these soils. The impacts of water content (0.11-1.50 g H(2)O g(-1) dry feedlot surface material [FSM]) and manure level (5, 25, and 75% dry manure in dry FSM) on E. coli O157:H7 in feedlot soils were evaluated. Generally, E. coli O157:H7 numbers either persisted or increased at all but the lowest moisture levels examined. Manure content modulated the effect of water on E. coli growth; for example, at water content of 0.43 g H(2)O g(-1) dry FSM and 25% manure, E. coli O157:H7 increased by 2 log(10) colony forming units (CFU) g(-1) dry FSM in 3 d, while at 0.43 g H(2)O g(-1) dry FSM and 75% manure, populations remained stable over 14 d. Escherichia coli and coliform populations responded similarly. In a second study, the impacts of cycling moisture levels and different drying rates on naturally occurring E. coli O157 in feedlot soils were examined. Low initial levels of E. coli O157 were reduced to below enumerable levels by 21 d, but indigenous E. coli populations persisted at > 2.50 log(10) CFU g(-1) dry FSM up to 133 d. We conclude that E. coli O157 can persist and may even grow in feedlot soils, over a wide range of water and manure contents. Further investigations are needed to determine if these variables can be manipulated to reduce this pathogen in cattle and the feedlot environment.

This study quantified sediment P flux in Lake Eucha, northeastern Oklahoma, USA, and evaluated the effectiveness of chemical treatment to reduce sediment P flux. Six intact sediment-water columns were collected from three sites in Lake Eucha near the reservoir channel at depths of 10 to 15 m. Three intact sediment and water columns from each site were incubated for 21 d at approximately 22 degrees C under aerobic conditions, and three were incubated under anaerobic conditions (N-2 with 300 ppm CO2); sediment P flux was estimated over the 21 d for each core. The overlying water in the cores was bubbled with air for approximately I wk and then treated with aluminum sulfate (alum). The cores were incubated at approximately 22 degrees C for an additional 14 d under aerobic or anaerobic conditions, and sediment P flux after alum treatment was estimated for each core. Sediment P flux was approximately four times greater under anaerobic conditions compared with aerobic conditions. Alum treatment of the intact sediment-water columns reduced (8X) sediment P flux under anaerobic conditions. Internal P flux (1.03 and 4.40 mg m(-2) d(-1) under aerobic and anaerobic conditions, respectively) was greater than external P flux (0.13 mg m(-2) d(-1)). The internal P load (12 Mg yr(-1)) from reservoir bottom sediments was almost 25% of the external P load (approximately 48 Mg yr(-1)) estimated using a calibrated watershed model.

Heat stress is one of the limiting factors in the production of fescues as forage in the southern Great Plains of the US. Heat responsive gene transcripts were cloned by using suppression subtractive hybridization between a heat-tolerant and a heat-sensitive fescue genotype subjected to a slowly increased temperature mimicking the natural conditions. The temperature in the growth chamber containing the plants was gradually increased from 24 degrees C to 44 degrees C over a period of 2 weeks. Three subtractions were conducted between samples of the two genotypes collected after 12 h of exposure to 39, 42, and 44 degrees C. A total of 2495 ESTs were generated, of which 1800 clustered into 434 contigs and 656 were singlets. The putative functions of ESTs were predicted by BLASTX. Nearly 30% of the contigs and 39% of the singlets had no similarity to GenBank sequences. Differentially expressed genes selected by subtractions were classified into 10 broad categories according to their putative functions generated by BLAST analysis. Under heat-stress conditions, cell maintenance, chloroplast associated and photosynthesis-, protein synthesis-, signalling-, and transcription factor-related genes had higher expression levels in the heat-tolerant genotype. Genes related to metabolism and stress had higher expression in the heat-sensitive genotype. The expression of 17 selected gene transcripts were examined by RT-PCR using plant tissues of the two genotypes grown under heat stress and under optimal temperature conditions (24 degrees C) for fescue. Results from RT-PCR confirmed the differential expressions of these transcripts. The differential expressions of at least 11 of these genes were attributable to heat stress rather than to differences in the genetic backgrounds of the genotypes.

Previous studies have shown that the initiation and rapid elongation of these fibres requires the expression of sucrose synthase (Sus) and, potentially, a transient closure of plasmodesmata. This study extends the previous work to examine the patterns of Sus expression and plasmodesmata gating in fuzz-like short fibres of a mutant that shows delayed initiation and much slower and reduced elongation of the fibre cells. Immunolocalization studies revealed delayed expression of Sus in the mutant seed-coat epidermis that correlates temporally and spatially with the initiation of the fibre cells. Anatomically, these short fibres differed from the normal lint in that their basal ends enlarged immediately after initiation, while the majority of the normal lint on wild-type seed did not show this enlargement until the end of elongation. Suppression of Sus expression in the seed-coat epidermis of the transgenic plants reduced the length of both lint and short fuzz fibres at maturity, suggesting that the growth of short fibres also requires high levels of Sus expression. Confocal imaging of the membrane-impermeant fluorescent solute carboxyfluorescein (CF) revealed no closure of plasmodesmata during the entire elongation period of short fibres from the mutant seed. These results show (i) the delayed initiation of fuzz-like short fibres from the mutant seed correlates with delayed or insufficient expression of Sus in a subset of seed-coat epidermal cells destined to become fibres and (ii) the much shortened elongation of the fibres from the mutant may be related to their inability to close plasmodesmata.

Their contents and isomer ratios in rice bran vary among southern US cultivars, suggesting that breeding for higher contents or a favorable ratio of these phytochemicals is feasible. Methods that can rapidly and reliably extract and quantify their contents in rice bran or whole rice kernel are necessary for breeding programs. A simple, one-step equilibrium extraction procedure coupled with reversed-phase (RP) HPLC is presented here. The one-min equilibrium extraction at a 1:60 (w/v) ratio of rice bran to methanol recovered 92 to 102% of the target phytochemicals relative to those of repeated, non-saponified, direct solvent extraction methods. At this 1:60 ratio of bran to solvent, isopropanol and methanol are superior extraction solvents relative to hexane. A modified, mobile-phase gradient with 10% of aqueous phase for the first 3-min eliminates all the methanol-soluble interfering compounds. This extraction method has the following advantages over the currently available methods: speed, no special extraction instrumentation is needed; and the extraction solvent, methanol, is compatible with subsequent quantification via RP-HPLC.

Juices from many of the varieties were high in malic acid and potassium. Mean values for many of the attributes did not match existing compositional database value means. However, some of the overall minimum and maximum values for the various attributes (i.e., Brixdegrees, pH, ash, TA, sucrose, glucose, fructose, sorbitol, malic, citric, fumaric, sodium, and calcium) in this study compared reasonably well with existing compositional database values. Distribution of phenolics between the various varieties was highly variable with some juices containing little if any phenolic compounds. Chlorogenic acid and phloridzin were detected in all varietal samples while arbutin and HMF were not measurable. The data developed should be useful with other databases in describing authentic apple juice and in the development of future apple commercial varieties to target specific consumer requirements.

A main effects log-linear Poisson regression model was constructed to evaluate the association between fiscal year and the rate of E. coli O157: H7-positive raw ground beef samples while controlling for the effect of season for the subset of test results obtained from fiscal year (FY)2000 through FY2003. Rate ratios were used to compare the rate of E. coli O157:H7-positive raw ground beef samples between sequential years to identify year-to-year differences. Of the 26,521 raw ground beef samples tested from FY2000 through FY2003, 189 (0.71%) tested positive for E. coli O157:H7. Year-to-year comparisons identified a 50% reduction in the rate of positive ground beef samples from FY2002 to FY2003 when controlling for season (95% CI, 10 to 72% decrease; P = 0.02). This decrease was the only significant year-to-year change in the rate of E. coli O157:H7-positive raw ground beef samples but was consistent in samples obtained from both federally inspected establishments and retail outlets. We believe this decrease is attributed to specific regulatory actions by Food Safety and Inspection Service and subsequent actions implemented by the industry, with the goal of reducing E. coli O157:H7 adulteration of raw ground beef. Continued monitoring is necessary to confirm that the decrease in the rate of E. coli O157:H7 in raw ground beef samples we observed here represents the beginning of a sustained trend.

In this study, we addressed the question of whether emulsification in, or growth on, wieners triggers a response in the listerial cells that makes them more virulent or protects them against the harsh environment of the gastrointestinal tract in mice. Our results indicate that Listeria monocytogenes Scott A grows poorly, if at all, in one brand of commercially prepared wieners inoculated with 5 X 10(3) to 5 X 10(6) CFU per package and incubated at 15degreesC. Neither L. monocytogenes Scott A emulsified in a slurry of homogenized wieners nor recovered from wiener package fluid after a 7-day incubation at 15degreesC were more virulent when inoculated into the stomachs of A/J mice than L. monocytogenes Scott A grown in brain heart infusion broth. These findings suggest that the ability of L. monocytogenes Scott A to cause systemic infection following introduction into the gastrointestinal tract was not improved by incubation with wieners or suspension in a meat matrix.

Three nalidixic acid-sensitive outbreak strains of Escherichia coli O157:H7 were used to generate mutants resistant to nalidixic acid (Nal(R), 50 mu g/mL) by successive culturing and selection in nalidixic acid-amended broth. The resistance to ionizing radiation of the parent and Nal(R) strains was determined (a) in a phosphate buffer solution and (b) on green leaf lettuce. The Nal(R) strains of each of the 3 isolates were significantly (P < 0.05) more sensitive to ionizing radiation than the nalidixic acid-sensitive (Nal(S)) parent strains in both systems. D-10 values (the amount of ionizing radiation required to achieve I log10 reduction) determined in buffer for the parent strains ranged from 0.18 to 0.33 kGy, whereas for the Nal(R) strains, D-10 were approximately 0.10 kGy, a reduction of up to 69%. When evaluated on green leaf lettuce, the D-10 for the Nal(S) strains was approximately 0.18 kGy as opposed to 0.10 to 0.12 kGy for the Nal(R) strains, a reduction of up to 45%. The D-10. values obtained on lettuce were significantly different-than those obtained in buffer for 4 of the 6 isolates examined. The magnitude of the increase in radiation sensitivity resulting from resistance to nalidixic acid varied among the strains tested and also varied depending on the suspending medium. These results suggest that the use of nalidixic acid resistance as a selective marker may result in significant overestimates of the antimicrobial efficacy of ionizing radiation against E. coli O157:H7.

However, B(f) and A(f) have limitations that can produce inaccurate assessments of model performance. Consequently, an objective of the current study was to develop a method for quantifying model performance that overcomes limitations of B(f) and A(f). Performance of published lag time and growth rate models for Salmonella Typhimurium were evaluated for data used in model development and for data not used in model development but that were inside (interpolation) or outside (extrapolation) the response surface of the models. In addition, performance of published models for growth of Escherichia coli O157:117 was evaluated for data used in model development. Observed and predicted values were compared using B(f), A(f), and pRE, a new performance factor that quantified the proportion of relative errors (RE) in an acceptable prediction zone from an RE of -0.3 (fail-safe) to 0.15 (fail-dangerous). A decision diagram based on criteria for test data and model performance was used to validate the models. When B(f) and A(f) were used to quantify model performance, all models were validated. In contrast, when pRE was used to evaluate model performance, 2 models for S. Typhimurium and both models for E. coli O157:117 failed validation. Overall, pRE was a more sensitive and reliable indicator of model performance than B(f) and A(f) because unacceptable pRE, which indicated a performance problem, were obtained for 8 of 20 evaluations, all of which had acceptable B(f) and A(f). A limitation of pRE was the inability to distinguish between global and regional prediction problems. However, when used in combination with an RE plot, pRE provided a complete evaluation of model performance that overcame limitations of B(f) and A(f).

However, there is not a sufficiently clear understanding of that relationship to allow sour taste intensity to be predicted and rationally modified in foods. On the basis of analysis of sensory data from our laboratory and re-analysis of previously published data, we propose a new hypothesis for the chemical basis for sour taste perception: The intensity of sour taste perception in acid solutions or acidified foods is linearly related to the molar concentration of all organic acid species with at least 1 protonated carboxyl group plus the molar concentration of free hydrogen ions. This hypothesis implies that, on a molar basis, different organic acids will be equally sour, provided at least 1 carboxyl group is protonated. The major effect of pH on sour taste will be to determine the degree of protonation of organic acids. If this hypothesis is confirmed, it will provide a new understanding of the chemical basis for this basic taste perception and have broad usefulness in the formulation of products in which sour taste is an important component of flavor.

In this study, the effects of calcium ascorbate (CaA) and ionizing radiation on quality of 'Gala' apple slices under modified atmosphere packaging were investigated. 'Gala' apple slices, treated with water or 7% CaA followed by either nonirradiation (0 kGy) or irradiation at 0.5 and 1.0 kGy, were stored at 10 degrees C for up to 3 wk. The titratable acidity, pH, firmness, ascorbic acid content, color, and microflora population were measured weekly throughout storage. Irradiation did not affect titratable acidity and pH of sliced apples. Fruit slices softened during irradiation and storage, but this decrease in firmness during storage was reduced by the CaA treatment. Although the ascorbic acid content of apple slices treated with CaA decreased rapidly during storage, the ascorbic acid content was always higher in those treated samples than in the apple slices treated with water. Irradiation decreased both V and hue values of apple slices. Hue values decreased during the entire storage period while L* increased during the 1st wk of storage, then decreased between 1 to 3 wk of storage. CaA increased L* and hue values of apple slices, suggesting CaA reduced browning, even in irradiated samples. The microflora population of apples slices was not affected by CaA, and CaA treatment did not alter the reduction in microflora by irradiation. The combination of CaA and irradiation enhanced microbial food safety while maintaining quality of fresh-cut apple slices. C1 USDA ARS, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

Stukenia pectinatus, Potamogeton nodosus, and Hydrilla verticillata (monoecious type) were grown in either monocultures or mixtures in polyvinylchloride containers. Four 5 cm diameter minirhizotrons were mounted horizontally across the containers so that they were 2.5, 12.5, 22.5, or 32.5 cm below the surface of the sediment, and we inserted a specialized video camera in each minirhizotron tube and recorded root images at 21 locations in each tube. For two of three cases, adding plants of another species changed the root depth distribution and increased the volume of soil occupied by roots compared to monocultures. Additionally, smaller diameter roots were more abundant when competitors were present. This implies that the plants adjusted to the presence of competitors by producing more roots capable of nutrient uptake. These results imply that competition for sediment-based nutrients occurred in these systems. C1 ARS, USDA, Exot & Invas Weeds Res Unit, Davis, CA 95616 USA.

The ammocoetes exhibited a highly aggregated, non-random spatial distribution pattern. Conductivity, dissolved oxygen, and gradient influenced ammocoete distribution at the large scale (across 50 m reaches), whereas wetted width, percent fines, canopy density, and velocity influenced distribution at the small scale (1 m(2) quadrats). We observed optimum water depths of 70 cm and current velocities of 0 to 10 cm/sec. In general, ammocoetes preferred fine substrates though larger ammocoetes were found at low densities in large gravel substrates. Our findings illustrate the importance of slow water environments for the rearing stage of Pacific lamprey. Restoration activities should be designed to restore watershed function and process in a way that naturally allows systems to retain these critical habitats. Additionally, when considering ammocoete habitat use and distribution, it is important to take into account the scale of the observations.

Studies of OvHV-2 have been hampered by the lack of an in vitro propagation system. Here, the use of nasal secretions collected from OvHV-2-infected sheep experiencing intense virus shedding episodes as a source of infectious virus for experimental animal infections was examined. OvHV-2 uninfected sheep were nebulized with nasal secretions containing approximately 10(8) to 10(1) copies of OvHV-2 DNA. The time to detectable viral DNA in peripheral blood leukocytes (7-12 days post-infection) and virus-specific antibody in plasma (9-32 days post-infection) varied with the dose of inocula administered. Here, the use of nasal secretions as a source of infectious OvHV-2 was defined and the minimum infectious dose of a pool of nasal secretions that can be used in further studies of viral pathogenesis and vaccine development was determined.

The linkage groups were assigned to chromosomes by deficiency analysis of probes in the previously published joinmap, based on genomic DNA from hypoaneuploid chromosome substitution lines. These findings were integrated with QTL identification for multiple fiber and yield traits. Overall results revealed the presence of 63 QTLs on five different chromosomes of the A subgenome (chromosomes-03, -07, -09, -10, and -12) and 29 QTLs on the three different D subgenome (chromosomes-14 Lo, -20, and the long arm of -26). Linkage group-1 (chromosome-03) harbored 26 QTLs, covering 117 cM with 54 RFLP loci. Linkage group-2, (the long arm of chromosome-26) harbored 19 QTLs, covering 77.6 cM with 27 RFLP loci. Approximately 49% of the putative 92 QTLs for agronomic and fiber quality traits were placed on the above two major joinmap linkage groups, which correspond to just two different chromosomes, indicating that cotton chromosomes may have islands of high and low meiotic recombination like some other eukaryotic organisms. In addition, it reveals highly recombined and putative gene abundant regions in the cotton genome. QTLs for fiber quality traits in certain regions are located between two RFLP markers with an average of less than one cM (0.4similar to0.6 Mb) and possibly represent targets for map-based cloning. Identification of chromosomal location of RFLP markers common to different intra- and interspecific-populations will facilitate development of portable framework markers, as well as genetic and physical mapping of the cotton genome.

Hardwood cuttings, treated or untreated with rooting hormone prior to sticking into rooting substrate, were grown with one of three isolates of EMF as inoculum or with no inoculum (control). Cutting's were placed under mist in a 'greenhouse, with no bottom heat, and harvested 63, 84 and 109 d after sticking. Cuttings in substrate inoculated with two of the three EMF isolates showed better rooting than in non-inoculated substrate 63 d after sticking. However, by the end of the experiment, there were no differences in rooting between cuttings in the different inoculation treatments. Only cuttings in pots inoculated with one of the EMF isolates had consistently higher root initiation and weight than non-inoculated cuttings at all harvest dates. Root initiation and weight of cuttings in pots inoculated with either of the other two EMF isolates were greater than non-inoculated cuttings only when the cuttings had been treated with rooting hormone. In General, roots on EMF-inoculated cuttings were less branched and longer than roots on non-inoculated cuttings. Root colonisation was positively correlated with root initiation, length and weight 63 d after sticking; while, at later harvest dates, root colonisation was positively correlated only with root weight. The ability of EMF to increase rooting during cutting propagation of easy-to-root species, may decrease root production time. EMF-induced increases in root initiation during cutting propagation appear to be related to specific plant-fungus interactions and to interactions with rooting hormone. Although there were isolate-specific differences in rooting response, EMF-induced changes in root size and anatomy appear to be time-dependent and may influence the function of the new root system relative to water use and nutrient uptake, as well as survival, during transplanting.

The catchments represented three common landscape types: Valley and Ridge-shale (Mahantango Creek), Valley and Ridge-carbonate (Buffalo Run), and Appalachian Plateau-sandstone (Benner Run). Samples were collected on a biweekly basis from May 18, 1999 to May 9, 2000. Precipitation, soil water, and baseflow isotopic composition data indicated that a seasonal recharge bias existed for these catchments, most recharge occurred in the fall, winter, and spring months. An altitude effect of -0.16 to -0.32%c/100 m change in elevation was discernible in precipitation, soil water, and stream baseflow isotopic compositions. Soils effectively damped seasonal variations of recharge O-18 composition after depths of 1.62-2.85 m. The greatest damping of the annual isotopic composition signal occurred in the shallow soil layers (0-15 cm). In these and similar landscapes with thick soils the annual isotopic composition signal may be completely damped prior to reaching the stream as baseflow. Isotopic variations measured in stream baseflow are more likely to be caused by the shallow flowpath water relatively close to the streams. Baseflow stable isotope variations found on the basins studied suggested that residence times for subsurface waters to reach channels were much longer than the annual seasonal cycle of 180 in precipitation. Damping depths were similar for the three different catchments but it is not certain how spatially variable damping depths were within each catchment. This information would be useful in determining areas within catchments that contribute to short term isotopic composition fluctuations within streams ('new water'). Predictive models that determine isotopic damping depth from meteorological, soil and vegetation/land-use data can help develop a better understanding of the variability of recharge and attenuation of contaminants across the landscape.

Analysis of the nucleotide sequence revealed 1 large open reading frame. The amino acid sequence of the translated open reading frame was most identical to structural proteins of SINV-1 (97%), followed by the Kashmir bee virus (KBV, 30%), and acute bee paralysis virus (ABPV, 29%). A PCR-based survey for SINV-1 and the new species or genotype (tentatively named S. invicta virus-1A, SINV-1A) using RNA extracts of S. invicta collected around Gainesville, Florida, revealed a mean colony infestation rate of 25% by SINV-1 and 55% by SINV-1A. Both SINV-1 and SINV-IA were found to co-infect 17.5% of the nests surveyed. Although the data preclude definitive species or genotype assignment, there is no doubt that SINV-IA is distinct from SINV-1, identifiable, and infects S. invicta. We provide a simple RT-PCR technique capable of discerning SINV-1 and SINV-1A infection of S. invicta. Published by Elsevier Inc. C1 USDA ARS, Ctr Med Agr & Vet Entomol, Gainesville, FL 32608 USA.

Cattle that survive acute infection become life-long persistently infected carriers. In the intermountain west the Rocky Mountain wood tick, Dermacentor andersoni Stiles, is the most common vector of A. marginale. Male D. andersoni acquire A. marginale when feeding on persistently infected cattle and biologically transmit it when they transfer from infected to susceptible hosts. Host-seeking adult D. andersoni were collected from four widely separated natural populations and tested for susceptibility to midgut colonization with A. marginale. Male ticks were fed on calves persistently infected with a strain of A. marginale naturally transmitted by D. andersoni. Gut infection rates ranged from 12.5% of ticks collected from a mountain site near Hamilton, MT, to 62.5% of ticks from a rangeland site near Riley, OR. Sites near Miles City, MT, and Kamloops, British Columbia, Canada, had intermediate levels of susceptibility. The infection rates differed significantly among populations, and the same populations sampled in two consecutive years were not significantly different from one year to the next. Although there was variation among the populations in the size of ticks, size was unrelated to acquisition of gut infection. Quantitative polymerase chain reaction (PCR) demonstrated that there was no significant difference between populations in the mean number of genome copies in the guts of infected ticks. A. marginale from infected ticks was genotyped to confirm that they were all infected with the laboratory strain, and a sample of 682 field-collected D. andersoni was surveyed for A. marginale by nested PCR; none were found to be naturally infected. Infection of the gut is an essential constituent of vector competence for A. marginale; in this study, we have demonstrated significant variation among populations in this key component of vector competence.
