AB OBJECTIVES: To describe patterns of antimicrobial use for respiratory tract infections (RTIs) in older residents of long-term care facilities (LTCFs).
DESIGN: Data from a prospective, randomized, controlled study of the effect of vitamin E supplementation on RTIs conducted from April 1998 through August 2001 were analyzed.
SETTING: Thirty-three LTCFs in the greater Boston area.
PARTICIPANTS: Six hundred seventeen subjects aged 65 and older residing in LTCFs.
MEASUREMENTS: RTIs, categorized as acute bronchitis, pneumonia, common cold, influenza-like illness, pharyngitis, and sinusitis, were studied for appropriateness of antimicrobial use, type of antibiotics used, and factors associated with their use. For cases in which drug treatment was administered, antibiotic use was rated as appropriate (when an effective drug was used), inappropriate (when a more-effective drug was indicated), or unjustified (when use of any antimicrobial was not indicated).
RESULTS: Of 752 documented episodes of RTI, overall treatment was appropriate in 79% of episodes, inappropriate in 2%, and unjustified in 19%. For acute bronchitis, treatment was appropriate in 35% and unjustified in 65% of cases. For pneumonia, treatment was appropriate in 87% of episodes. Of the most commonly used antimicrobials, macrolide use was unjustified in 43% of cases. No statistically significant differences in the patterns of antibiotic use were observed when stratified according to age, sex, race, or comorbid conditions, including diabetes mellitus, dementia, and chronic kidney disease.
CONCLUSION: Antimicrobials were unjustifiably used for one-fifth of RTIs and more than two-thirds of cases of acute bronchitis, suggesting a need for programs to improve antibiotic prescribing at LTCFs. J Am Geriatr Soc 59:1093-1098, 2011.

DE Bioterrorism; arboterrorism; vector-borne pathogens; mosquito control
AB The release of infected mosquitoes or other arthropods by bioterrorists, i.e., arboterrorism, to cause disease and terror is a threat to the USA. A workshop to assess mosquito control response capabilities to mount rapid and effective responses to eliminate an arboterrorism attack provided recommendations to improve capabilities in the USA. It is essential that mosquito control professionals receive training in possible responses, and it is recommended that a Council for Emergency Mosquito Control be established in each state to coordinate training, state resources, and actions for use throughout the state.

AB Two experimental techniques were used to test the water permeability of two Korean hardwood species: diffuse porous Populus tomentiglandulosa T. Lee (eunsasi poplar) and ring porous white oak, Quercus serrata Thunb (konara oak). The first technique measured the void volume filled at different moisture content (MC) levels. Samples were treated with water via a schedule of full-cell impregnation. A significant relation between MC and permeability (the fractional void volume) was found. A reduction in liquid permeability was observed at MC above the fiber saturation point (FSP), whereas the opposite result was observed at MC below FSP due to the effect of the voids available in the wood. However, the differences of increased permeability from MC level 20% to 0% were found satistically the same in either wood species. The second technique measured the speed of liquid penetration in vessels, fibers, and rays with no application of external pressure. In this method, liquid flow was captured via video and the penetration speed was measured. Vessels, fibers, and rays in poplar were found to be more permeable than those in oak. Different anatomical factors such as cell diameter, cell length, pit number, pit aperture area, and thickness of the pit membrane seemed to be responsible for the variation of liquid flow rate in different cells of the two hardwood species.

AB Upregulation of the antioxidant enzyme system in plants provides protection against various abiotic stresses. Transgenic potato plants overexpressing the strawberry D-galacturonic acid reductase (GalUR) gene with enhanced accumulation of ascorbate (AsA) were used to study the antioxidant system involving the ascorbate-glutathione cycle in order to understand the tolerance mechanism in plants in response to various abiotic stresses under in vitro conditions. Transgenic potato tubers subjected to various abiotic stresses induced by methyl viologen, sodium chloride and zinc chloride showed enhanced activities of superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.1.1.1.6) and enzymes of the ascorbate-glutathione cycle such as ascorbate peroxidase (APX, EC 1.11.1.11), dehydroascorbate reductase (DHAR, EC 1.8.5.1) and glutathione reductase (GR, EC 1.8.1.7), as well as increased levels of ascorbate, glutathione (GSH) and proline when compared to untransformed tubers. The increased enzyme activities correlated with the mRNA transcript levels in the stressed transgenic tubers. Significant differences in redox status of AsA and GSH were also observed in stressed transgenic potato tubers that showed increased tolerance to abiotic stresses compared to untransformed tubers. This study suggests that the increased accumulation of AsA could upregulate the antioxidant system which imparts improved tolerance against various abiotic stresses in transgenic tubers compared to untransformed tubers.

AB Phosphonate reagents were developed for the two-carbon homologation of aldehydes or ketones to unbranched- or methyl-branched alpha,beta-unsaturated aldehydes. The phosphonate reagents, diethyl methylformyl-2-phosphonate dimethylhydrazone and diethyl ethylformyl-2-phosphonate dimethylhydrazone, contained a protected aldehyde group instead of the usual ester group. A homologation cycle entailed condensation of the reagent with the starting aldehyde, followed by removal of the dimethylhydrazone protective group with a biphasic mixture of 1 M HCl and petroleum ether. This robust two-step process worked with a variety of aldehydes and ketones. Overall isolated yields of unsaturated aldehyde products ranged from 71% to 86% after the condensation and deprotection steps.

AB The BASIC PENTACYSTEINE (BPC) proteins are a plant-specific transcription factor family that is present throughout land plants. The Arabidopsis BPC proteins have been categorized into three classes based on sequence similarity, and we demonstrate that there is functional overlap between classes. Single gene mutations produce no visible phenotypic effects, and severe morphological phenotypes occur only in higher order mutants between members of classes I and II, with the most severe phenotype observed in bpc1-1 bpc2 bpc4 bpc6 plants. These quadruple mutants are dwarfed and display small curled leaves, aberrant ovules, altered epidermal cells and reduced numbers of lateral roots. Affected processes include coordinated growth of cell layers, cell shape determination and timing of senescence. Disruption of BPC3 function rescues some aspects of the bpc1-1 bpc2 bpc4 bpc6 phenotype, indicating that BPC3 function may be antagonistic to other members of the family. Ethylene response is diminished in bpc1-1 bpc2 bpc4 bpc6 plants, although not all aspects of the phenotype can be explained by reduced ethylene sensitivity. Our data indicate that the BPC transcription factor family is integral for a wide range of processes that support normal growth and development.

AB The plant-pathogenic fungus Mycosphaerella graminicola (asexual stage: Septoria tritici) causes septoria tritici blotch, a disease that greatly reduces the yield and quality of wheat. This disease is economically important in most wheat-growing areas worldwide and threatens global food production. Control of the disease has been hampered by a limited understanding of the genetic and biochemical bases of pathogenicity, including mechanisms of infection and of resistance in the host. Unlike most other plant pathogens, M. graminicola has a long latent period during which it evades host defenses. Although this type of stealth pathogenicity occurs commonly in Mycosphaerella and other Dothideomycetes, the largest class of plant-pathogenic fungi, its genetic basis is not known. To address this problem, the genome of M. graminicola was sequenced completely. The finished genome contains 21 chromosomes, eight of which could be lost with no visible effect on the fungus and thus are dispensable. This eight-chromosome dispensome is dynamic in field and progeny isolates, is different from the core genome in gene and repeat content, and appears to have originated by ancient horizontal transfer from an unknown donor. Synteny plots of the M. graminicola chromosomes versus those of the only other sequenced Dothideomycete, Stagonospora nodorum, revealed conservation of gene content but not order or orientation, suggesting a high rate of intra-chromosomal rearrangement in one or both species. This observed "mesosynteny'' is very different from synteny seen between other organisms. A surprising feature of the M. graminicola genome compared to other sequenced plant pathogens was that it contained very few genes for enzymes that break down plant cell walls, which was more similar to endophytes than to pathogens. The stealth pathogenesis of M. graminicola probably involves degradation of proteins rather than carbohydrates to evade host defenses during the biotrophic stage of infection and may have evolved from endophytic ancestors.

AB The emergence and rapid global spread of the swine-origin H1N1/09 pandemic influenza A virus in humans underscores the importance of swine populations as reservoirs for genetically diverse influenza viruses with the potential to infect humans. However, despite their significance for animal and human health, relatively little is known about the phylogeography of swine influenza viruses in the United States. This study utilizes an expansive data set of hemagglutinin (HA1) sequences (n = 1516) from swine influenza viruses collected in North America during the period 2003-2010. With these data we investigate the spatial dissemination of a novel influenza virus of the H1 subtype that was introduced into the North American swine population via two separate human-to-swine transmission events around 2003. Bayesian phylogeographic analysis reveals that the spatial dissemination of this influenza virus in the US swine population follows long-distance swine movements from the Southern US to the Midwest, a corn-rich commercial center that imports millions of swine annually. Hence, multiple genetically diverse influenza viruses are introduced and co-circulate in the Midwest, providing the opportunity for genomic reassortment. Overall, the Midwest serves primarily as an ecological sink for swine influenza in the US, with sources of virus genetic diversity instead located in the Southeast (mainly North Carolina) and South-central (mainly Oklahoma) regions. Understanding the importance of long-distance pig transportation in the evolution and spatial dissemination of the influenza virus in swine may inform future strategies for the surveillance and control of influenza, and perhaps other swine pathogens.

AB An image processing algorithm for detecting individual weeds was developed and evaluated. Weed detection processes included were normalized excessive green conversion, statistical threshold value estimation, adaptive image segmentation, median filter, morphological feature calculation and Artificial Neural Network (ANN). The developed algorithm was validated for its ability to identify and detect weeds and crop plants under uncontrolled outdoor illuminations. A machine vision implementing field robot captured field images under outdoor illuminations and the image processing algorithm automatically processed them without manual adjustment. The errors of the algorithm, when processing 666 field images, ranged from 2.1 to 2.9%. The ANN correctly detected 72.6% of crop plants from the identified plants, and considered the rest as weeds. However, the ANN identification rates for crop plants were improved up to 95.1% by addressing the error sources in the algorithm. The developed weed detection and image processing algorithm provides a novel method to identify plants against soil background under the uncontrolled outdoor illuminations, and to differentiate weeds from crop plants. Thus, the proposed new machine vision and processing algorithm may be useful for outdoor applications including plant specific direct applications (PSDA).

TI Importance of Carolina Bays to the Avifauna of Pinelands in the
Southeastern United States
SO SOUTHEASTERN NATURALIST

AB Past anthropogenic activity has led to the destruction or alteration of Carolina bay wetlands throughout the southeastern United States. Presently, urban development, combined with a 2001 ruling by the US Supreme Court relaxing protection of isolated wetlands, poses an increasing threat to these and other isolated wetland systems; however, little information exists on the importance of these wetland systems to birds. We compared breeding and wintering bird communities of upland pine (Pinus spp.) forests with and without Carolina bays. Estimated species richness was greater in pine forests with Carolina bays than without during the winter (31.7 +/- 1.3 [mean +/- SE] vs. 26.9 +/- 1.2; P = 0.027), but not in the breeding season (27.9 +/- 2.2 vs. 26.3 +/- 2.2; P = 0.644). Total relative abundance did not differ between pine forests with Carolina bays and those without in either the breeding (148.0 +/- 16.0 vs. 129.4 +/- 10.4 birds/40 ha; P = 0.675) or winter (253.0 +/- 36.4 vs. 148.8 +/- 15.1 birds/40 ha; P = 0.100) seasons. However, 23 species, 43% of which were wetland-dependent, were observed only in pine forests with bays during the breeding season, and 20 species, 30% of which were wetland-dependent, were observed only in such sites during winter. In contrast, only 6 and 1 species were observed only in pine forests without bays during the breeding and winter seasons, respectively, indicating that few species were negatively affected by the presence of bays. Thus, Carolina bays appear to enrich the avifauna of pine forests in the southeastern United States.

AB The objective of this study was to evaluate 152 sugarcane microsatellite (simple sequence repeats, SSRs) markers originally developed in India for their transferability to germplasm being used by sugarcane breeders in the U.S. The commercial sugarcane cultivar, LCP 85-384, was used for the initial screening of the SSR markers because it is a parent in many of the most recently released cultivars. Ten wild clones representing five related Saccharum species were also used in a follow-up screen, namely, S. officinarum, S. spontaneum, S. robustum, S. sinense, and S. barberi. Of 152 SSR markers tested, 110 (70%) primed the amplification of PCR products from the genomic DNA of LCP 85-384, of which 39 were derived from genomic sequences and 71 were derived from expressed sequence tags (ESTs). Twenty-three SSR markers that amplified relatively higher yields of PCR products migrating as a single intensely stained band were chosen for further evaluation on the 10 wild clones using a capillary electrophoresis (CE)-based genotyping platform and fluorescently-labeled primers. Sizes of amplified DNA fragments were accurately computed against GS500 DNA size standards. A total of 200 DNA fragments (alleles) were scored, of which 199 fragments were polymorphic, averaging 8.7 polymorphic alleles per marker, with sizes ranging from 100 to 505 bp. The polymorphism information content (PIC) values of these 23 SSR markers varied from 0.42 to 0.90. It is anticipated that many of the SSR markers evaluated in this study can be used by the Louisiana sugarcane breeders to differentiate varieties and their cross progeny as well as to develop DNA maps for traits (characteristics) of interest in the hopes of developing trait-specific markers. It is also expected that the results reported in this paper can be a good reference for sugarcane breeders in other countries where Indian sugarcane germplasm are routinely utilized in their genetic improvement programs.

ID OBJECTIVE EVALUATION; SMOOTHNESS APPEARANCE
AB In this paper we present a novel wrinkle evaluation method that uses modified wavelet coefficients and optimized support-vector-machine (SVM) classifications to characterize and classify the wrinkling appearance of fabric. Fabric images were decomposed with the wavelet transform, and five parameters were defined, based on the modified wavelet coefficients, to describe wrinkling features, such as orientation, hardness, density, and contrast. These parameters were also used as the inputs of optimized SVM classifiers to obtain overall wrinkle grading in accordance with the standard American Association of Textile Chemists and Colorists smoothness appearance (SA) replicas. The SVM classifiers, based on a linear kernel and a radial-basis-function kernel, were used in the study. The effectiveness of this evaluation method was tested by 300 images of five selected fabrics that had different fiber contents, weave structures, colors, and laundering cycles. The cross-validation tests on the SA classifications indicated that the SA grades of more than 75% of these diversified samples could be recognized correctly. The extracted wrinkle parameters provided useful information for textile, appliance, and detergent manufactures to inspect wrinkling behaviors of fabrics.

AB This research examined the expression patterns of 94 stress-related genes in seven maize inbred lines with differential expressions of resistance to aflatoxin contamination. The objective was to develop a set of genes/probes associated with resistance to A. flavus and/or aflatoxin contamination. Ninety four genes were selected from previous gene expression studies with abiotic stress to test the differential expression in maize lines, A638, B73, Lo964, Lo1016, Mo17, Mp313E, and Tex6, using real-time RT-PCR. Based on the relative-expression levels, the seven maize inbred lines clustered into two different groups. One group included B73, Lo1016 and Mo17, which had higher levels of aflatoxin contamination and lower levels of overall gene expression. The second group which included Tex6, Mp313E, Lo964 and A638 had lower levels of aflatoxin contamination and higher overall levels of gene expressions. A total of six. cross-talking. genes were identified between the two groups, which are highly expressed in the resistant Group 2 but down-regulated in susceptible Group 1. When further subjected to drought stress, Tex6 expressed more genes up-regulated and B73 has fewer genes up-regulated. The transcript patterns and interactions measured in these experiments indicate that the resistant mechanism is an interconnected process involving many gene products and transcriptional regulators, as well as various host interactions with environmental factors, particularly, drought and high temperature.

AB At this time, no "magic bullet" for solving the aflatoxin contamination problem in maize and cottonseed has been identified, so several strategies must be utilized simultaneously to ensure a healthy crop, free of aflatoxins. The most widely explored strategy for the control of aflatoxin contamination is the development of preharvest host resistance. This is because A. flavus infects and produces aflatoxins in susceptible crops prior to harvest. In maize production, the host resistance strategy has gained prominence because of advances in the identification of natural resistance traits. However, native resistance in maize to aflatoxin contamination is polygenic and complex and, therefore, markers need to be identified to facilitate the transfer of resistance traits into agronomically viable genetic backgrounds while limiting the transfer of undesirable traits. Unlike maize, there are no known cotton varieties that demonstrate enhanced resistance to A. flavus infection and aflatoxin contamination. For this reason, transgenic approaches are being undertaken in cotton that utilize genes encoding antifungal/anti-aflatoxin factors from maize and other sources to counter fungal infection and toxin production. This review will present information on preharvest control strategies that utilize both breeding and native resistance identification approaches in maize as well as transgenic approaches in cotton.

TI Genetic change in the open reading frame of bovine viral diarrhea virus
is introduced more rapidly during the establishment of a single

STRAINS; BVDV; HERD; IDENTIFICATION; CONSEQUENCES
AB Bovine viral diarrhea viruses (BVDV) are ubiquitous viral pathogens of cattle with a high degree of sequence diversity amongst strains circulating in livestock herds. The driving force behind change in sequence is not well established but the inaccurate replication of the genomic RNA by a viral RNA polymerase without proof-reading capabilities as well as immune pressure on immunodominant proteins are thought to play major roles. Additionally, it is not clear when the majority of changes are introduced, whether during acute infections with exposure to innate and adaptive immune responses or in establishment of persistent infections (PI) in utero. To examine which generates greater sequence diversity, two groups of viruses were compared. The first was six isolates of a single strain of BVDV-2 that were isolated over greater than a year's time. These viruses caused a series of severe acute (SA) BVD outbreaks over a large geographic area. Changes in nucleotide sequence were determined by comparison of the sequence of each strain to the six virus consensus sequence. The second group was composed of six BVDV strains isolated from PI calves whose dams were exposed to PI cattle. Changes were identified by comparison of the sequence of the progenitor PI virus to that of the progeny viruses from the single in vivo 'passage'. The open reading frames (OAF) of the six SA isolates were >99% identical at the nucleotide level with 30% of the changes being nonsynonymous changes. The amount of genetic change increased with time and distance from the original outbreak. Similarly, the PI viruses isolated from single passage PI calves had >99% identity with the progenitor virus. The number of nucleotide changes in these viruses was equal to or greater than that observed in the SA viruses. The majority of the nonsynonymous changes were found in the structural proteins, with 65% of these occurring in the immunodominant E2 protein. Antigenic mapping studies using a monoclonal antibody panel specific for the BVDV E2 protein showed no antigenic differences amongst the six SA viruses, nor between the progenitor and progeny type la and type 2 persistent viruses. However, antigenic differences were observed in the two type 1b progeny viruses that possessed the greatest number of amino acid changes. Two antibodies were found to have altered staining patterns. These results suggest that the establishment of a single persistent infection results in more rapid generation of genetic diversity in BVDV strains than a series of acute infections and may contribute to antigenic change in the absence of an immune response.

AB Recent studies show that green tea polyphenols (GTPs) attenuate bone loss and microstructure deterioration in ovariectomized aged female rats, a model of postmenopausal osteoporosis. This study evaluated the efficacy of GTPs at mitigating bone loss and microstructure deterioration along with related mechanisms in androgen-deficient aged rats, a model of male osteoporosis. A 2 (sham vs. orchidectomy) x 2 (no GTP and 0.5% GTP in drinking water) factorial design was studied for 16 weeks using 40 aged male rats. An additional 10 rats (baseline group) were killed at the beginning of study to provide baseline parameters. There was no difference in femoral mineral density between baseline and the sham only group. Orchidectomy suppressed serum testosterone and tartrate-resistant acid phosphatase concentrations, liver glutathione peroxidase activity, bone mineral density, and bone strength. Orchidectomy also decreased trabecular bone volume, number, and thickness in the distal femur and proximal tibia and bone-formation rate in trabecular bone of proximal tibia but increased serum osteocalcin concentrations and bone-formation rates in the endocortical tibial shaft. GTP supplementation resulted in increased serum osteocalcin concentrations, bone mineral density, and trabecular volume, number, and strength of femur; increased trabecular volume and thickness and bone formation in both the proximal tibia and periosteal tibial shaft; decreased eroded surface in the proximal tibia and endocortical tibial shaft; and increased liver glutathione peroxidase activity. We conclude that GTP supplementation attenuates trabecular and cortical bone loss through increasing bone formation while suppressing bone resorption due to its antioxidant capacity.

AB Quantum mechanics (QM) and molecular mechanics (MM) calculations were performed to elucidate Young's moduli for a series of cellulose I-beta models. Computations using the second generation empirical force field MM3 with a disaccharide cellulose model, 1,4'-O-dimethyl-beta-cellobioside (DMCB), and an analogue, 2,3,6,2',3',6'-hexadeoxy-1,4'-O-dimethyl-beta-cellobioside (DODMCB), that cannot make hydrogen bonds reveal a considerable contribution of intramolecular hydrogen bonding to the molecular stiffness of cellulose I-beta; the moduli for DMCB and DODMCB being 85.2 and 37.6 GPa, respectively. QM calculations confirm this contribution with modulus values of 99.7 GPa for DMCB and 33.0 GPa for DODMCB. However, modulus values for DMCB were considerably lower than values previously reported for cellulose I-beta. MM calculations with extended cellulose chains (10-40 glucose units) resulted in modulus values, 126.0-147.5 GPa, more akin to the values reported for cellulose I-beta. Comparison of the cellodecaose model, 1,4'-O-dimethyl-beta-cellodecaoside (DMCD), modulus with that of its hydrogen bonding-deficient analogue, 2,3,6,2',3',6'-hexadeoxy-1,4'-O-dimethyl-beta-cellodecaoside (DODMCD), corroborates the observed stiffness conferred by intramolecular hydrogen bonds; the moduli for DMCD and DODMCD being 126.0 and 63.3 GPa, respectively. Additional MM3 determinations revealed that modulus values were not strongly affected by intermolecular hydrogen bonding, with multiple strand models providing values similar to the single strand models; 87.5 GPa for a 7-strand DMCB model and 129.5 GPa for a 7 strand DMCD model.

Weight average molar masses ranged from about 96 to 220 x 10(3) Daltons, weight average intrinsic viscosity from 1.9 to 4.1 dL/g and degree of substitution from 1.38 to 0.59. HPSEC with online molar mass detectors and Atomic Force Microscopy revealed that CMC was comprised of aggregated linear moieties in contact with spherical bodies. The linear portion was a mixture of rods and segmented rods. Some of the rods had long branches.

AB Effective population size (N-e) determines the strength of genetic drift in a population and has long been recognized as an important parameter for evaluating conservation status and threats to genetic health of populations. Specifically, an estimate of N-e is crucial to management because it integrates genetic effects with the life history of the species, allowing for predictions of a population's current and future viability. Nevertheless, compared with ecological and demographic parameters, N-e has had limited influence on species management, beyond its application in very small populations. Recent developments have substantially improved N-e estimation; however, some obstacles remain for the practical application of N-e estimates. For example, the need to define the spatial and temporal scale of measurement makes the concept complex and sometimes difficult to interpret. We reviewed approaches to estimation of N-e over both long-term and contemporary time frames, clarifying their interpretations with respect to local populations and the global metapopulation. We describe multiple experimental factors affecting robustness of contemporary N-e estimates and suggest that different sampling designs can be combined to compare largely independent measures of N-e for improved confidence in the result. Large populations with moderate gene flow pose the greatest challenges to robust estimation of contemporary N-e and require careful consideration of sampling and analysis to minimize estimator bias. We emphasize the practical utility of estimating N-e by highlighting its relevance to the adaptive potential of a population and describing applications in management of marine populations, where the focus is not always on critically endangered populations. Two cases discussed include the mechanisms generating N-e estimates many orders of magnitude lower than census N in harvested marine fishes and the predicted reduction in N-e from hatchery-based population supplementation.

AB Understanding the spatial dimensions of hunting and prey population dynamics is important in order to estimate the sustainability of hunting in tropical forests. We investigated how hunting offtake of vertebrates differed in mixed forest and monodominant forest (composed of Gilbertiodendron dewevrei) and over different spatial extents within the hunting catchment around the logging town of Kabo, Congo. In 9 months of recall surveys with hunters, we gathered information on over 1500 hunting trips in which ungulates were 65% of the species killed and 82% of harvested biomass. Hunters supplied information on animals killed and the hunting trip, including the area visited (i.e., hunting zone; 11 separate zones within a 506 km(2) catchment or commonly hunted area). Over 65% of all animals were killed in monodominant forest, which made up 28% of the hunting catchment, and zones with small amounts of monodominant forest were used most frequently by hunters. Given the large offtakes from monodominant forests, we suggest that animal dispersal may be maintaining high, localized harvests in these areas. We believe hunters preferred to hunt in monodominant forest because the understory was accessible and that areas with small amounts of monodominant forest and large amounts of mixed forest were more productive. The variation in hunting pressure we found between and within hunting zones differs from past examinations of spatial variation in hunting offtake, where entire hunting catchments were considered population sinks and areas with low to no hunting (no-take zones) were outside hunting catchments. Future use of no-take zones to manage hunting should incorporate variability in offtake within hunting catchments.

AB Purpose of review
Our purpose is to review recent findings highlighting the metabolic and functional diversity of HDL subspecies.
Recent findings
HDL heterogeneity - both structural and functional - is the main focus of this review. Recent work indicates that the metabolism and functionality of HDL particles differ greatly among HDL subspecies. With the introduction of new and improved methodology (e.g., proteomics), new aspects of the structural complexity and functionality of HDL have been revealed. It has been confirmed that HDL functions including, but not limited to decreasing inflammation, apoptosis, macrophage adhesion to the endothelium and insulin resistance - are due to HDL's ability to remove cholesterol from cells (reverse cholesterol transport). A new level of HDL complexity has recently been revealed by investigating the lipid composition of HDL with gas chromatography, gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. There are about 100 different HDL-associated proteins; however, there are many more lipid species potentially associated with HDL particles.
Summary
The most important recent findings disclose that HDL is more complex than previously thought. HDL subclasses differ in physical-chemical properties, protein and lipid composition, metabolism, physiological functions and pathophysiological significance. The staggering complexity of HDL demands significantly more investigation before we can truly begin to understand HDL metabolism and function in humans.

AB P>Biological invasions are a global and increasing threat to the function and diversity of ecosystems. Allee effects (positive density dependence) have been shown to play an important role in the establishment and spread of non-native species. Although Allee effects can be considered a bane in conservation efforts, they can be a benefit in attempts to manage non-native species. Many biological invaders are subject to some form of an Allee effect, whether due to a need to locate mates, cooperatively feed or reproduce or avoid becoming a meal, yet attempts to highlight the specific exploitation of Allee effects in biological invasions are surprisingly unprecedented. In this review, we highlight current strategies that effectively exploit an Allee effect, and propose novel means by which Allee effects can be manipulated to the detriment of biological invaders. We also illustrate how the concept of Allee effects can be integral in risk assessments and in the prioritization of resources allocated to manage non-native species, as some species beset by strong Allee effects could be less successful as invaders. We describe how tactics that strengthen an existing Allee effect or create new ones could be used to manage biological invasions more effectively.

AB Fruits containing high antioxidant capacities and other bioactivities are ideal for promoting longevity and health span. However, few fruits are known to improve the survival and health span in animals, let alone the underlying mechanisms. Here we investigate the effects of nectarine, a globally consumed fruit, on life span and health span in Drosophila melanogaster. Wild-type flies were fed standard, dietary restriction (DR), or high-fat diet supplemented with 0-4% nectarine extract. We measured life span, food intake, locomotor activity, fecundity, gene expression changes, and oxidative damage indicated by the level of 4-hydroxynonenal-protein adduct in these flies. We also measured life span, locomotor activity, and oxidative damage in sod1 mutant flies on the standard diet supplemented with 0-4% nectarine. Supplementation with 4% nectarine extended life span, increased fecundity, and decreased expression of some metabolic genes, including a key gluconeogenesis gene, PEPCK, and oxidative stress-response genes, including peroxiredoxins, in female wild-type flies fed the standard, DR, or high-fat diet. Nectarine reduced oxidative damage in wildtype females fed the high-fat diet. Moreover, nectarine improved the survival of and reduced oxidative damage in female sod1 mutant flies. Together, these findings suggest that nectarine promotes longevity and health span partly by modulating glucose metabolism and reducing oxidative damage. Published by Elsevier Inc.

AB We evaluated the genetic contribution of the leukotriene (LT) pathway to risk of coronary artery disease (CAD) in 4,512 Caucasian and African American subjects ascertained through elective cardiac evaluation. Of the three previously associated variants, the shorter "3" and "4" alleles of a promoter repeat polymorphism in ALOX5 increased risk of CAD in African Americans (OR = 1.4, 95% CI 1.0-1.9; p = 0.04), whereas a haplotype of LTA4H (HapK) was associated with CAD in Caucasians (OR = 1.2, 95% CI 1.01-1.4; p = 0.03). In Caucasians, first-stage analysis of 254 haplotype-tagging SNPs in 15 LT pathway genes with follow-up of 19 variants in stage 2 revealed an LTA4H SNP (rs2540477) that increased risk of CAD (OR = 1.2, 95% CI 1.1-1.5; p = 0.003) and a PLA2G4A SNP (rs12746200) that decreased risk of CAD (OR = 0.7, 95% CI 0.6-0.9; p = 0.0007). The PLA2G4A rs12746200 variant also decreased risk of experiencing a major adverse cardiac event (MACE = myocardial infarction, stroke, or death) over 3 years of follow-up (HR = 0.7, 95% CI 0.5-0.9; p = 0.01), consistent with its cardioprotective effect. Functional experiments demonstrated that stimulated monocytes from carriers of LTA4H variants HapK or rs2540477 had 50% (p = 0.002) and 33% (p = 0.03) higher LTB(4) production, respectively, compared to non-carriers. These ex vivo results are consistent with LTB(4) being the direct product of the reaction catalyzed by LTA4H and its role in promoting monocyte chemotaxis to sites of inflammation, including the artery wall of atherosclerotic lesions. Taken together, this study provides additional evidence that functional genetic variation of the LT pathway can mediate atherogenic processes and the risk of CAD in humans.

AB The aim of this study was to assess the independent contributions of plasma levels of lipoprotein(a) (Lp(a)), Lp(a) cholesterol, and of apo(a) isoform size to prospective coronary heart disease (CHD) risk. Plasma Lp(a) and Lp(a) cholesterol levels, and apo(a) isoform size were measured at examination cycle 5 in subjects participating in the Framingham Offspring Study who were free of CHD. After a mean follow-up of 12.3 years, 98 men and 47 women developed new CHD events. In multivariate analysis, the hazard ratio of CHD was approximately two-fold greater in men in the upper tertile of plasma Lp(a) levels, relative to those in the bottom tertile (P < 0.002). The apo(a) isoform size contributed only modestly to the association between Lp(a) and CHD and was not an independent predictor of CHD. In multivariate analysis, Lp(a) cholesterol was not significantly associated with CHD risk in men. In women, no association between Lp(a) and CHD risk was observed. Elevated plasma Lp(a) levels are a signifi cant and independent predictor of CHD risk in men. The assessment of apo(a) isoform size in this cohort does not add signifi cant information about CHD risk. In addition, the cholesterol content in Lp(a) is not a signifi cant predictor of CHD risk.

AB Developing animals must resolve the conflicting demands of survival and growth, ensuring that they can function as infants or juveniles while developing toward their adult form. In the case of the mammalian skull, the cranium and mandible must maintain functional integrity to meet the feeding needs of a juvenile even as the relationship between parts must change to meet the demands imposed on adults. We examine growth and development of the cranium and mandible, using a unique ontogenetic series of known-age coyotes (Canis latrans), analyzing ontogenetic changes in the shapes of each part, and the relationship between them, relative to key life-history events. Both cranial and mandibular development conform to general mammalian patterns, but each also exhibits temporally and spatially localized maturational transformations, yielding a complex relationship between growth and development of each part as well as complex patterns of synchronous growth and asynchronous development between parts. One major difference between cranium and mandible is that the cranium changes dramatically in both size and shape over ontogeny, whereas the mandible undergoes only modest shape change. Cranium and mandible are synchronous in growth, reaching adult size at the same life-history stage; growth and development are synchronous for the cranium but not for the mandible. This synchrony of growth between cranium and mandible, and asynchrony of mandibular development, is also characteristic of a highly specialized carnivore, the spotted hyena (Crocuta crocuta), but coyotes have a much less protracted development, being handicapped relative to adults for a much shorter time. Morphological development does not predict life-history events in these two carnivores, which is contrary to what has been reported for two rodent species. The changes seen in skull shape in successive life-history stages suggest that adult functional demands cannot be satisfied by the morphology characterizing earlier life-history stages. J.

AB Objective To evaluate the effects of early bronchopulmonary dysplasia (BPD) on calcium (Ca) metabolism and growth in very low birth weight (VLBW) infants.
Study design A dual-tracer, stable isotope method was used to assess Ca absorption in VLBW infants. Infants with early BPD received energy-dense feedings and mild fluid restriction.
Results Sixteen of 41 preterm infants were classified as having early BPD. Fractional Ca absorption (early BPD, 58.4 +/- 4.6% versus no early BPD, 50.3 +/- 4.0%, P = .2), total Ca absorption (early BPD, 127 +/- 14 mg/kg/d versus no early BPD, 104 +/- 9 mg/kg/d, P = .9), and Ca retention (early BPD, 99.6 +/- 10.0 mg/kg/d versus no early BPD, 91.0 +/- 9.8 mg/kg/d, P = .2) were similar among groups. There was no significant difference in weight gain, linear growth, or head circumference growth between groups.
Conclusions The ability of VLBW infants with early BPD and fluid restriction to grow and accrete calcium is similar to those without early BPD. The use of high caloric density feedings in VLBW infants with early BPD can help achieve bone and overall growth outcomes close to those achievable in utero. (J Pediatr 2011;158:885-90).

AB The role of vertebrates as amplifying and maintenance hosts for vesicular stomatitis New Jersey virus (VSNJV) remains unclear. Livestock have been considered dead-end hosts because detectable viraemia is absent in VSNJV-infected animals. This study demonstrated two situations in which cattle can represent a source of VSNJV to Simulium vittatum Zetterstedt (Diptera: Simuliidae) by serving: (a) as a substrate for horizontal transmission among co-feeding black flies, and (b) as a source of infection to uninfected black flies feeding on sites where VSNJV-infected black flies have previously fed. Observed co-feeding transmission rates ranged from 0% to 67%. Uninfected flies physically separated from infected flies by a distance of up to 11 cm were able to acquire virus during feeding although the rate of transmission decreased as the distance between infected and uninfected flies increased. Acquisition of VSNJV by uninfected flies feeding on initial inoculation sites at 24 h, 48 h and 72 h post-infection, in both the presence and absence of vesicular lesions, was detected.

AB A growing body of evidence indicates that in some cases morphology-based species circumscription of lichenized fungi misrepresents the number of existing species. The cosmopolitan "rock posy" lichen (Rhizoplaca melanophthalma) species-complex includes a number of morphologically distinct species that are both geographically and ecologically widespread, providing a model system to evaluate speciation in lichen-forming ascomycetes. In this study, we assembled multiple lines of evidence from nuclear DNA sequence data, morphology, and biochemistry for species delimitation in the R. melanophthalma species-complex. We identify a total of ten candidate species in this study, four of which were previously recognized as distinct taxa and six previously unrecognized lineages found within what has been thus far considered a single species. Candidate species are supported using inferences from multiple empirical operational criteria. Multiple instances of sympatry support the view that these lineages merit recognition as distinct taxa. Generally, we found little corroboration between morphological and chemical characters, and previously unidentified lineages were morphologically polymorphic. However, secondary metabolite data supported one cryptic saxicolous lineage, characterized by orsellinic-derived gyrophoric and lecanoric acids, which we consider to be taxonomically significant. Our study of the R. melanophthalma species-complex indicates that the genus Rhizoplaca, as presently circumscribed, is more diverse in western North American than originally perceived, and we present our analyses as a working example of species delimitation in morphologically cryptic and recently diverged lichenized fungi.

MATURATION
AB Although mated females of the western tarnished plant bug Lygus hesperus Knight are known to produce more eggs than virgins, the nature of the inducing stimuli and the specific changes occurring in the female require additional elucidation. Compared with virgin females isolated from males, those exposed to male precopulatory behaviours produce similar numbers of eggs, whereas inseminated females produce 50% more during the observation period. Although the quantity of seminal fluids received by a female does not influence egg number, mating twice within a 10-day span causes a 16% increase in fecundity, on average. Females mating more than twice during the same period do not exhibit additional increases in egg number. Because virgin females contain more chorionated eggs than are laid, mating appears to enhance the rate of oviposition. However, to achieve a sustained increase in fecundity, an augmented rate of oocyte maturation would also be required. Male-derived spermatophores lack substantive quantities of nutrients that might otherwise have enhanced female fecundity. The total amounts of carbohydrate, protein and lipid, as well as eight essential minerals transferred by the male, are insufficient for producing even a single egg, and the female has already produced a large number of chorionated oocytes before she mates. Collectively, the data suggest that seminal fluid contains one or more activational molecules, such as a peptide, which triggers an increase in egg deposition. A prolonged increase in oviposition rate may be achieved through multiple matings to ensure a supply of sperm or to offset the degradation of the putative activational factor.

AB Potato (Solanum tuberosum L.) tubers contain a wide range of carotenoid contents. To decipher the key factors controlling carotenoid levels in tubers, four potato lines (Atlantic, Desiree, 91E22 and POR03) were examined by a combination of biochemical, molecular and genomics approaches. These lines contained incremental levels of carotenoids, which were found to be associated with enhanced capacity of carotenoid biosynthesis as evident from norflurazon treatment. Microarray analysis of high and low carotenoid lines (POR03 versus Atlantic) revealed 381 genes that showed significantly differential expression. The carotenoid metabolic pathway genes beta-carotene hydroxylase 2 (BCH2) and beta-carotene hydroxylase 1 (BCH1), along with zeaxanthin epoxidase (ZEP), and carotenoid cleavage dioxygenase 1A (CCD1A) were among the most highly differentially expressed genes. The transcript levels of BCH2 and BCH1 were lowest in Atlantic and highest in POR03, whereas those of ZEP and CCD1A were high in low carotenoid lines and low in high carotenoid lines. The high expression of BCH2 in POR03 line was associated with enhanced response to sugars. Our results indicate that high levels of carotenoid accumulation in potato tubers were due to an increased metabolic flux into carotenoid biosynthetic pathway, as well as the differential expression of carotenoid metabolic genes.

AB Guar seed gum, consisting primarily of a high molecular weight galactomannan, is the most cost effective natural thickener, having broad applications in the food, cosmetics, paper, pharmaceutical and petroleum industries. The properties of the polymer can potentially be enhanced by genetic modification. Development of suitable endosperm-specific promoters for use in guar is desirable for metabolic engineering of the seed gum. A similar to 1.6 kb guar mannan synthase (MS) promoter region has been isolated. The MS promoter sequence was fused with the GUS reporter gene and overexpressed in the heterologous species alfalfa (Medicago sativa). The potential strength and specificity of the MS promoter was compared with those of the constitutive 35S promoter and the seed specific beta-phaseolin promoter. Quantitative GUS assays revealed that the MS promoter directs GUS expression specifically in endosperm in transgenic alfalfa. Thus, the guar MS promoter could prove generally useful for directing endosperm-specific expression of transgenes in legume species.

AB Salinity is an important environmental factor limiting growth and productivity of plants, and affects almost every aspect of the plant physiology and biochemistry. The objective of this study was to apply cDNA-AFLP and to identify differentially expressed genes in response to NaCl stress vs. no-stress in Populus simonii x Populus nigra in order to develop genetic resources for genetic improvement. Selective amplification with 64 primer combinations allowed the visualization of 4407 transcript-derived fragments (TDFs), and 2027 were differentially expressed. Overall, 107 TDFs were re-sequenced successfully, and 86 unique sequences were identified in 10 functional categories based on their putative functions. A subset of these genes was selected for real-time PCR validation, which confirmed the differential expression patterns in the leaf tissues under NaCl stress vs. no stress. Differential expressed genes will be studied further for association with salt or drought-tolerance in P. simonii x P. nigra. This study suggests that cDNA-AFLP is a useful tool to serve as an initial step for characterizing transcriptional changes induced by NaCl salinity stress in P. simonii x P. nigra and provides resources for further study and application in genetic improvement and breeding. All unique sequences have been deposited in the Genbank as accession numbers GW672587-GW672672 for public use. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

Blends With Chain Extenders, Thermoplastic Elastomer, and/or
Poly(butylene adipate-co-terephthalate)
SO POLYMER ENGINEERING AND SCIENCE
LA English
DT Article
AB Poly(ethylene terephthalate) (PET) resin is one of the most widely used thermoplastics, especially in packaging. Because thermal and hydrolytic degradations, recycled PET (RPET) exhibits poor mechanical properties and lacks moldability. The effects of adding elastomeric modifiers, chain extenders (CE), and poly(butylene adipate-co-terephthalate), PBAT, as a toughener to RPET on its moldability and mechanical property were investigated. Melt blending of RPET with CE, thermoplastic elastomer (TPE), and/or PBAT was performed in a thermokinetic mixer (K-mixer). The blended materials were then injection molded to produce tensile specimens. Various techniques were used to study the mechanical properties, rheological properties, compatibility, and crystallization behavior of the RPET blends. By melt blending with proper additives, recycled PET regained its moldability, thereby enabling the recycling of RPET. Furthermore, the addition of CE greatly enhanced the mechanical properties of RPET. While the RPET and TPE blends also showed improved mechanical properties, the improvement was less significant and the blends were often immiscible due to the difference in polarities between RPET and TPE. Finally, it was found that the mechanical properties of RPET blends depended on the prior thermal history of the material and could be improved with an extra annealing step that increased the degree of crystallinity.

AB Small farms in Appalachia need management options that diversify income opportunities, are adaptable to new livestock management strategies, and help maintain environmental integrity. Plantings of temperate bamboo (Poaceae), including species native to West Virginia, were established to determine the potential nutritive value for small ruminants, such as goats (Capra hircus), at different times of the year. The bamboo species we evaluated, included several Phyllostachys spp., Semiarundiaria fastuosa and Arundinaria gigantea, were able to withstand Appalachian winter temperatures and retain some green leaves even in late winter. Although small differences were evident, the nutritive value was generally comparable among species and exhibited similar trends over the season. Total non-structural carbohydrates in bamboo leaves decreased throughout the growing season, and then remained stable or increased during winter. Conversely, crude protein was relatively low in young leaves compared to late season or over-wintered leaves. Concentrations of fiber and protein were sufficient to meet the maintenance needs of adult goats. The ability of bamboo to remain green and maintain the nutritive value throughout winter suggested that it has potential as winter forage for goats in central Appalachia. As an upright browse, bamboo may reduce the exposure of goats to gastrointestinal parasites. Perennial stands of temperate bamboo could prove to be a valuable, multiple-use crop suitable for Appalachian farm operations and easily adaptable to goat production systems.

AB The development of standardised nomenclatures with associated databases containing reference sequences for alleles at polymorphic loci within the major histocompatibility complex (MHC) has been facilitated by the development of the immuno polymorphism database (IPD). Recently, included within IPD-MHC is information on allelic diversity within sheep species (IPD-MHC-OLA). Here, we present the first report of progress in populating the sheep IPD-MHC database with alleles at the class II MHC DRB1 locus. The sequence of 63 Ovar-DRB1 alleles within 24 allelic families is now held within the database, each meeting the minimum requirement of a complete second exon. These sequences are derived from a combination of genomic and cDNA-based approaches and represent the most extensive collection of validated alleles at the sheep DRB1 locus yet described. Although these 63 alleles probably represent only a fraction of the DRB1 allelic diversity in sheep species worldwide, we encourage the research community to use the official allelic nomenclature and to contribute allelic sequences to the database via its web-based submission tool. In time, the IPD-MHC-OLA resource will underpin population-based MHC genotyping studies and help to simplify meta-analyses of multi-source data from wild and domestic sheep populations.

AB The majority of genomic research in conifers has been conducted in the Pinus subgenus Pinus mostly due to the high economic importance of the species within this taxon. Genetic maps have been constructed for several of these pines and comparative mapping analyses have consistently revealed notable synteny. In contrast, little genomic research has been conducted on the Pinus subgenus Strobus, even though these pines have strong ecological relevance. We report a consensus genetic linkage map for sugar pine (Pinus lambertiana Dougl.) constructed with 399 single nucleotide polymorphisms markers derived from annotated genes. The map is 1,231 cM in length and organized into 19 linkage groups. Two of the mapping populations were derived from trees that were segregating for the major gene of resistance (Cr1) to Cronartium ribicola, the fungal pathogen responsible for white pine blister rust. The third mapping population was derived from a full-sib cross segregating for partial resistance to white pine blister rust. In addition, we report the first comparative mapping study between subgenera Strobus and Pinus. Sixty mapped markers were found in common between sugar pine and the loblolly pine reference map with 56 of them (93%) showing collinearity. All 19 linkage groups of the sugar pine consensus map coaligned to the 12 linkage groups of the loblolly pine reference map. The syntenic relationship observed between these two clades of pines provides a foundation for advancing genomic research and genetic resources in subgenus Strobus.

AB Butternut (Juglans cinerea L.) is a temperate deciduous hardwood native to the eastern USA and southern Canada valued for its nuts and wood. Butternut's survival is threatened by butternut canker, a disease caused by the exotic fungus Sirococcus clavigignenti-juglandacearum Nair, Kostichka & Kuntz. Field observations indicate that trees commonly called buartnut (a hybrid of butternut and its close congener Japanese walnut (Juglans ailantifolia x J. cinerea)) may be more resistant to butternut canker than is either parental species. Hybrids are difficult to distinguish morphologically from butternuts, and scientists have expressed concern over the possibility of range-wide genetic invasion by Japanese walnut via hybridization with butternut. We used pair-wise combinations of 40 random primers to screen bulked DNA pools of butternut, Japanese walnut, and buartnuts to identify genomic regions unique to Japanese walnut. We ultimately identified one ITS region marker, one chloroplast marker, one mitochondrial marker, and six nuclear markers. The utility of the markers for identifying hybrids was tested and verified using more than 190 genotypes. The markers will be used to identify buartnut hybrids based on the presence of introgressed genomic fragments inherited from Japanese walnut. We confirmed that hybrids have a complex genetic history and present features of the parental species in all possible combinations. These results will assist in the identification and testing of (non-hybrid) butternut for breeding and reintroduction of the species to its former habitats.

AB P > In a prospective field observational study in the southeastern USA, we sampled gastrointestinal (GI) tracts from chicks of 65 broiler flocks delivered to conventional grow-out farms for rearing. The flocks were hatched at seven broiler hatcheries. The mean within-flock prevalence of Salmonella-positive samples was 6.5% and ranged from 0% to 86.7%. Of the 65 flocks studied, 25 (38.5%) had at least one Salmonella-positive sample. Accounting for confounding variability among the hatcheries and broiler companies, we tested whether the probability of detecting Salmonella in GI tracts of the chicks delivered was associated with certain characteristics of parent breeder flocks; hatchery production volume; hatchery ventilation system; hatchery egg-room conditions; egg incubation, candling, hatching, eggshell and bird separation, and bird-processing procedures; management of hatchery-to-farm transportation; day of week of hatch; weather conditions during transportation; or season of the hatch. Two risk factor models were adopted. The first model indicated that a greater number of parent flocks, manual separation of eggshell and bird, and a greater amount of fluff and feces on tray liners used during hatchery-to-farm transportation at delivery were associated with increased probability of detecting Salmonella in chick GI tracts, whereas a greater number of birds in the delivery vehicle was associated with decreased probability. The second model indicated that broiler flocks hatched on Tuesdays versus either Mondays or Thursdays (with no hatches on Wednesdays, Fridays or week-ends), increased average hatchability of the eggs from the parent flocks, and greater amounts of fluff and feces on the transport tray liners at delivery were all associated with increased probability of detecting Salmonella in chick GI tracts. The results of this study suggest potential management decisions to lessen Salmonella contamination of broilers supplied by commercial hatcheries and areas for further research.

AB A novel process using chemical, thermal, and enzymatic treatment for conversion of hulled barley into fermentable sugars was developed. The purpose of this process is to convert both lignocellulosic polysaccharides and starch in hulled barley grains into fermentable sugars simultaneously without a need for grinding and hull separation. In this study, hulled barley grains were treated with 0.1 and 1.0 wt.-% sulfuric acid at various temperatures ranging from 110 to 170 A degrees C in a 63-ml flow-through packed-bed stainless steel reactor. After sulfuric acid pretreatment, simultaneous conversion of lignocellulose and starch in the barley grains into fermentable sugars was performed using an enzyme cocktail, which included alpha-amylase, glucoamylase, cellulase, and beta-glucosidase. Both starch and non-starch polysaccharides in the pre-treated barley grains were readily converted to fermentable sugars. The treated hulled barley grains, including their hull, were completely hydrolyzed to fermentable sugars with recovery of almost 100% of the available glucose and xylose. The pretreatment conditions of this chemical, thermal, and enzymatic (CTE) process for achieving maximum yield of fermentable sugars were 1.0 wt.% sulfuric acid and 110 A degrees C. In addition to starch, the acid pretreatment also retained most of the available proteins in solid form, which is essential for subsequent production of fuel ethanol and high protein distiller's dried grains with solubles co-product.

AB Capture rates of insectary-reared female Aedes albopictus (Skuse), Anopheles quadrimaculatus Say, Culex nigripalpus Theobald, Culex quinquefasciatus Say and Aedes triseriatus (Say) in CDC-type light traps (LT) supplemented with CO2 and using the human landing (HL) collection method were observed in matched-pair experiments in outdoor screened enclosures. Mosquito responses were compared on a catch-per-unit-effort basis using regression analysis with LT and HL as the dependent and independent variables, respectively. The average number of mosquitoes captured in 1min by LT over a 24-h period was significantly related to the average number captured in 1min by HL only for Cx. nigripalpus and Cx. quinquefasciatus. Patterns of diel activity indicated by a comparison of the mean response to LT and HL at eight different times in a 24-h period were not superposable for any species. The capture rate efficiency of LT when compared with HL was <= 15% for all mosquitoes except Cx. quinquefasciatus (43%). Statistical models of the relationship between mosquito responses to each collection method indicate that, except for Ae. albopictus, LT and HL capture rates are significantly related only during certain times of the diel period. Estimates of mosquito activity based on observations made between sunset and sunrise were most precise in this regard for An. quadrimaculatus and Cx. nigripalpus, as were those between sunrise and sunset for Cx. quinquefasciatus and Ae. triseriatus.

TI Response of progeny bred from Bolivian and North American cultivars in
integrated management systems for leaf spot of peanut (Arachis hypogaea)
SO CROP PROTECTION

DT Article
DE Peanut breeding; Disease resistance; Leaf spot
ID REDUCED TILLAGE; EXPOSURE
AB Early and late leaf spot (caused by Cercospora arachidicola and Cercosporidium personatum, respectively) are major yield-reducing diseases of peanut (Arachis hypogaea L) in the southeastern U.S. Effective suppression of both early and late leaf spot, collectively called 'leaf spot', can be reached with integrated disease management (IDM) systems utilizing peanut cultivars with moderate levels of resistance to these pathogens. A Bolivian landrace cultivar, Bayo Grande, and a series of progeny breeding lines were evaluated under two IDM systems consisting of various reduced application fungicide regimes and/or tillage treatments in field experiments over two years. In the absence of fungicides or when averaged across fungicide regimes, Bayo Grande and breeding lines had better leaf spot resistance when compared to cultivars Georgia Green, MDR-98 and C-99R in all experiments across years. The addition of three or four fungicide applications to Bayo Grande and several of the breeding lines suppressed leaf spot to levels similar to those genotypes and Georgia Green under the full regime. Conservation tillage reduced the need for fungicides in most genotypes in both years. Yields were higher for Bayo Grande and the breeding lines compared to Georgia Green in three of the four experiments across years. When compared across genotype, yields were greatest for the full season fungicide regime, except in 2002 when yields were similar for all treatments. Leaf spot severity was reduced in conservation tillage compared to conventional tillage in most varieties in the absence of fungicides. However, yields tended to be lower in conservation tillage treatments than in conventional tillage. Under conservation tillage, yields of Bayo Grande and two of the breeding lines were negatively impacted in one year and were overall lower in the other year. Several of these new Bolivian-derived genotypes show promise for use in a reduced fungicide and/or conservation tillage IDM system with the potential to lessen fungicide use compared to standard production practices while maintaining low leaf spot levels and high yields.

AB The effects of water stress on Fusarium foot and root rot in durum wheat were investigated in growth chamber, greenhouse and field tests in Tunisia. In the seedling stage, emergence of six durum wheat cultivars in the growth chamber was significantly reduced by inoculation with Fusarium culmorum and water stress (P < 0.0001), with more disease under drier conditions. Additionally, the tiller number per mature plant, the 1000 grain weight and disease severity in mature stage were reduced by inoculation in greenhouse studies. In a field test, inoculation with E culmorum significantly reduced the yield (P < 0.001), by more than 17% for Om Rabiaa and 38% for Karim, the two cultivars tested. Yield was also significantly affected by precipitation and irrigation levels. The severity of the disease, estimated by the percentage of white heads, was separately affected by the cultivar (P < 0.001) and inoculation (P = 0.0004). Percentage of white heads was 1.5 and 2 x higher in inoculated plants than non-inoculated for Om Rabiaa and Karim cultivars, respectively. Disease severity was highest in treatments with the greatest water stress. This is the first detailed study of water stress and E culmorum on durum wheat in Tunisia, and indicates that cultivar resistance and irrigation management may be important in the management of Fusarium foot rot.

AB We examined the effect of saccharin on the systemic acquired resistance (SAR) response of soybean to the fungus Phakopsora pachyrhizi, the causal agent of soybean rust. Plants were grown hydroponically in half-strength Hoagland's solution and were challenged with the pathogen 1, 5, 10 and 15 d after treatment with 3 mM saccharin applied either as a foliar spray or a root drench at the 2nd trifoliate (V3) and early reproductive (R1) stages. Plants were destructively harvested and assessed for visible rust symptoms 2 wk after inoculation. Mode of saccharin application was a significant factor influencing the severity of rust infection. Saccharin applied as a root drench was more effective than the foliar spray treatment at inducing SAR, with increased resistance observed 1 d after application. Systemic protection against rust infection was still apparent 15 d after application of saccharin as a root drench. In contrast, foliar treatment with saccharin did not increase systemic protection until 15 d after treatment. When systemic protection was induced by the application of saccharin in either manner, there was no significant reduction of plant growth, except when plants were inoculated 15 d after the saccharin application as a root drench at the R1 stage of development.

AB 1. The exotic phloem-feeding emerald ash borer (EAB), Agrilus planipennis, has killed tens of millions of North American ash trees (Fraxinus) since its first detection in the U. S. A. in 2002. Ash trees are killed by larval feeding in the cambial region, which disrupts translocation of photosynthates and nutrients.
2. We observed that EAB larvae feed predominantly downwards in naturally grown green ash trees, a behaviour confirmed in greenhouse-grown black ash seedlings. Furthermore, biomass of larvae feeding downwards was greater than that for larvae feeding upwards.
3. We sought to determine the relative importance of four selection forces (i.e. gravity, moisture content, plant defence, and nutrition) in driving this downward feeding behaviour in this study. The gravity and plant defence (i.e. polyphenols) hypotheses were ruled out because even when seedlings were grown upside down, more EAB larvae moved upwards (towards the root area), and phloem tissue below the feeding site contained higher concentrations of defensive compounds than that above the feeding site.
4. The moisture content hypothesis was supported as phloem moisture above the feeding site decreased to levels reducing survivorship and biomass but was unaffected below. The nutrition hypothesis was also supported as the levels of 11 amino acids (mostly essential amino acids) below the feeding site were greater than those above. Furthermore, growth of larvae reared on an artificial diet deficient in protein and amino acids was worse than larvae reared in diet with complete ingredient or diet deficient in either protein or amino acids.
5. We conclude that moisture content and nutrients are two selective forces for the downward feeding behaviour of EAB larvae.

AB The common bacterial blight pathogen [Xanthomonas axonopodis pv. phaseoli (Xap)] is a limiting factor for common bean (Phaseolus vulgaris L.) production worldwide and resistance to the pathogen in most commercial cultivars is inadequate. Variability in virulence of the bacterial pathogen has been observed in strains isolated from Puerto Rico and Central America. A few common bean lines show a differential reaction when inoculated with different Xap strains, indicating the presence of pathogenic races. In order to study the inheritance of resistance to common bacterial blight in common bean, a breeding line that showed a differential foliar reaction to Xap strains was selected and was crossed with a susceptible parent. The inheritance of resistance to one of the selected Xap races was determined by analysis of segregation patterns in the F(1), F(2), F(3) and F(4) generations from the cross between the resistant parent PR0313-58 and the susceptible parent 'Rosada Nativa'. The F(1), F(2) and F(3) generations were tested under greenhouse conditions. Resistant and susceptible F(3:4) sister lines were tested in the field. The statistical analysis of all generations followed the model for a dominant resistance gene. The resistant phenotype was found to co-segregate with the SCAR SAP6 marker, located on LG 10. These results fit the hypothesis that resistance is controlled by a single dominant gene. The symbol proposed for the resistance gene is Xap-1 and for the bacterial race, XapV1.

AB Several species of fungi and oomycetes including Fusarium, Rhizoctonia, Phytophthora and Pythium have been reported as root pathogens of apple where they contribute to a phenomenon known as apple replant disease. In South Africa, little is known about specific species in these genera and their pathogenicity toward apple. Therefore, these aspects were investigated along with the development and optimization of qPCR tests for detection and quantification of the most virulent oomycete species. In eight investigated orchards, the oomycete Phythophthora cactorum was widely distributed, while nine Pythium species were differentially distributed among the orchards. Pythium irregulare was the most widely distributed and the most virulent species along with P. sylvaticum, P. vexans and Ph. cactorum. Seven binucleate Rhizoctonia anastomosis groups (AGs) were also differentially distributed among the orchards, with the majority appearing to be non-pathogenic while certain AG-I and AG-F isolates exhibited low virulence on apple. In the genus Fusarium, F. oxysporum was widely distributed, but isolates were non-pathogenic. Fusarium solani and F. avenaceum were less frequently encountered, with only some isolates having low virulence. qPCR data obtained from seedling roots inoculated with the most virulent Pythium species (P. irregulare, P. sylvaticum and P. vexans) and the genus Phytophthora were not always reproducible between trials, or isolates of the same species. In general, seedling growth inhibition was associated with the presence of a low amount of pathogen DNA (+/- 40 fg mu l(-1) to 2 pg mu l(-1)) in roots. Pythium irregulare, although having the lowest DNA concentrations in roots, was the only species for which a significant negative correlation was found between seedling weight and pathogen DNA concentration.

AB P>1. Quantification of stomatal responses to environmental variables, in particular to soil water status, is needed to model carbon and water exchange rates between plants and the atmosphere.
2. Models based on stomatal optimality theory successfully describe leaf gas exchange under different environmental conditions, but the effects of water availability on the key optimization parameter [the marginal water use efficiency (WUE), lambda = partial derivative A/partial derivative E] has resisted complete theoretical treatment. Building on previous optimal leaf gas exchange models, we developed an analytical equation to estimate lambda from gas exchange observations along gradients of soil water availability. This expression was then used in a meta-analysis of about 50 species to investigate patterns of variation in lambda.
3. Assuming that cuticular water losses are negligible lambda increases under mild water stress but decreases when severe water stress limits photosynthesis. When cuticular conductance is considered, however, lambda increases monotonically with increasing water stress, in agreement with previous theoretical predictions. Moreover, the shape of these response curves to soil water availability changes with plant functional type and climatic conditions. In general, lambda is lower in species grown in dry climates, indicating lower marginal WUE.
4. The proposed parameterization provides a framework to assess the responses of leaf gas exchange to changes in water availability. Moreover, the model can be extended to scale leaf-level fluxes to the canopy and ecosystem level.

AB Baseline data on rates of sediment transport provide useful information on the inherent variability of stream processes and may be used to assess departure in channel form or process from disturbances. In August 2000, wildfire burned portions of the Little Granite Creek watershed near Bondurant, WY where bedload and suspended sediment measurements had been collected during 13 previous runoff seasons. This presented an opportunity to quantify increases in sediment loads associated with a large-scale natural disturbance. The first three years post-fire were warm and dry, with low snowpacks and few significant summer storms. Despite relatively low flows during the first runoff season, the estimated sediment load was about five times that predicted from regression of data from the pre-burn record. Increased sediment loading occurred during the rising limb and peak of snowmelt (54%) and during the few summer storms (44%). While high during the first post-fire year, total annual sediment yield decreased during the next two years, indicating an eventual return to baseline levels. The results from this sediment monitoring lacked some of the more dramatic responses that have been observed in other watersheds following fire. In other environments, moderate-to-high intensity rainstorms caused significant flooding, widespread debris flows and channel incision and aggradation. A few moderate intensity storms (< 2 year recurrence interval) occurred in the Little Granite Creek watershed, but they did not trigger this type of response. Instead, ash and charcoal rich discharges (herein described as "blackwater flows") and heavily sediment laden flows were observed without physical evidence of debris flows, as defined by channel incision into previously unchanneled areas. Speculatively, the sedimentation pattern and geomorphic response in Little Granite Creek may be fairly typical of stream responses to wildfire during times of continued drought and in the absence of widespread, significant rainfall, representing one type of response on a continuum of effects following wildfire.

AB Hztransib, recently identified from Helicoverpa zea, represents the first intact and transcriptionally active Transib element. Its open reading frame was detected in Helicoverpa armigera, from which H. zea evolved, and in Helicoverpa assulta, the common ancestor of H. zea and H. armigera, but its remaining parts were found only in H. armigera. Thirty-nine Hztransib insertion sites, all of which are polymorphic, were detected from eight populations of H. zea. Out of the 39 insertion sites, 35 were not frequently occupied, with 1-33 occurrences in a total of 128 individuals from the eight populations (16 larvae per population). Its copy number ranged from 5.8 to 14.2 per individual, with putative intact copies always more abundant than internally deleted ones. Taking this evidence together, Hztransib probably transferred to H. zea from H. armigera and most likely still retains its capacity to maintain structural integrity, increase copy number and remobilize in H. zea.

AB Honeybees have evolved a social immunity consisting of the cooperation of individuals to decrease disease in the hive. We identified a set of genes involved in this social immunity by analysing the brain transcriptome of highly varroa-hygienic bees, who efficiently detect and remove brood infected with the Varroa destructor mite. The function of these candidate genes does not seem to support a higher olfactory sensitivity in hygienic bees, as previously hypothesized. However, comparing their genomic profile with those from other behaviours suggests a link with brood care and the highly varroa-hygienic Africanized honeybees. These results represent a first step toward the identification of genes involved in social immunity and thus provide first insights into the evolution of social immunity.

AB Although photosynthetic thermotolerance has been investigated extensively in cotton leaves, reports on the biochemical influence of the pistil in promoting fertilization thermostability are limited. To evaluate the effect of temperature, genotype, and exogenous calcium application on fertilization and pistil biochemistry in cotton, thermosensitive (cv. ST4554 B2RF) and thermotolerant (cv. VH260) plants were grown under control (30/20 degrees C) or high-temperature (38/20 degrees C) conditions during flowering, and exogenous CaCl(2) was applied to flowers 1 day prior to anthesis. Measured pistil parameters included fertilization efficiency; protein concentration; glutathione reductase, superoxide dismutase (SOD) and NADPH oxidase activities; and ATP and calcium levels. Exogenous calcium had no effect on reproductive thermostability due to poor calcium uptake under high temperature. High temperature resulted in a 19.2 % decline in fertilization efficiency for ST4554 but no change in fertilization efficiency for VH260 relative to optimal temperature conditions. Pre-stress glutathione reductase and SOD activities were higher in VH260 than ST4554 pistils, and calcium and ATP content were higher in VH260 than ST4554 pistils. It was concluded that pre-stress antioxidant enzyme activity, ATP and calcium content of the pistil may be associated with reproductive thermotolerance in cotton. These findings should be confirmed in future experiments with a larger number of cultivars.

AB Nutrients and grazers both can regulate benthic algal structure and function in streams, but the relative strength of each factor depends on stream biotic and abiotic conditions. The abundance of stream organisms and nutrient availability can change rapidly after a flood. Thus, nutrient and grazer influences on algal development and how these drivers interact may vary temporally during recovery. We measured benthic structural and functional development for 35 d after a simulated flood in large outdoor mesocosms under a gradient of 6 nutrient loadings crossed with 6 densities of grazing fish (Southern redbelly dace, Phoxinus erythrogaster). Nutrients influenced algal development more than dace did and were better correlated with algal function (area-specific primary productivity and nutrient uptake) than with structure (biomass). Dace influenced all structural variables and biomass-specific gross primary productivity, but their influence was relatively weak and was observed only early in recovery. Dace influence weakened and nutrient influence strengthened during recovery. Understanding context-dependent relationships in postdisturbance community dynamics is essential for predicting ecosystem responses to future changes in nutrient inputs and biodiversity, particularly in systems, such as headwater streams, with frequent disturbance.

AB We examined seasonal patterns of abundance of mussel larvae (glochidia) in stream drift in a diverse, large-stream mussel assemblage in the Sipsey River, Alabama, across 1 y. We used recently developed techniques for glochidial identification combined with information about mussel fecundity and benthic assemblages to evaluate how well observed glochidial abundance corresponded to expected abundance based on glochidial production. Glochidia from short-term brooding species (Amblema plicata, Elliptio arca, Fusconaia cerina, Pleurobema decisum, Obliquaria reflexa, and Quadrula asperata) were abundant from May to August but did not occur in drift between November and the end of April. Long-term brooders (Lampsilis spp., Medionidus acutissimus, Obovaria unicolor, and Villosa spp.) occurred in several short peaks in spring, summer, and autumn, but generally were less abundant than short-term brooders. We estimated that the benthic assemblage at our study site produced >500,000 glochidia/m(2) annually and production varied widely among species. Abundance of species in the drift was positively related to benthic abundance but was only weakly related to glochidial production. The poor relationship between glochidial production and abundance in the drift suggests that release and transport of glochidia are influenced by a wide variety of abiotic and biotic factors.

AB In this experimental study, conducted in coastal Oregon USA, we examined how small increases in summer water temperatures affected aquatic insect growth and autumn emergence. We maintained naturally fluctuating temperatures from 2 nearby streams and a 3(rd) regime, naturally fluctuating temperatures warmed by 3-5 degrees C, in flow-through troughs from mid-summer until autumn. We added selected abundant Ephemeroptera, Plecoptera, and Trichoptera species to the 3 treatments in late July and observed emergence until early December. We described the taxon-specific responses of the caddisfly Psychoglypha bella and the mayfly Paraleptophlebia bicornuta, both of which survived well in the troughs (67-86%), and the stonefly Mesocapnia projecta, which we did not collect in mid-summer but had colonized all experimental troughs by October. We observed primarily phenological rather than morphological responses to higher water temperatures. The most synchronous emergence of male and female P. bella and P. bicornuta occurred in the trough with the coolest temperatures. Only P. bella emerged asynchronously from the trough with the warmest temperatures. The decreases in synchrony were largely the result of earlier emergence of males. Paraleptophlebia bicornuta were larger and tended towards asynchrony in the trough with water (and temperatures) from their natal stream. Individuals in the trough with the warmest temperature were smaller than individuals in other troughs, but did not emerge earlier. Mesocapnia projecta showed greater synchrony in emergence, which occurred over a shorter interval, than the other species. When exposed to increased water temperatures, autumn-emergent taxa may be most vulnerable to trade-offs between asynchronous emergence and the probabilities for finding mates in unpredictable weather conditions.

AB ADP-glucose pyrophosphorylase (ADPGp, EC 2.7.7.27) is a tetrameric protein composed of two small and two large subunits that catalyzes the biosynthesis of ADP-glucose from glucose-phosphate which is used to provide the glucose subunits for starch biosynthesis. A second cotton gene encoding an ADPGp small subunit has been cloned and characterized. The gene contains eight introns similar to previously reported potato and cotton ADPGp small subunit genes. The deduced translation of the gene contained a poorly conserved transit peptide and well conserved catalytic and regulatory elements typical of other plant ADPGps. The 5' end of the mRNA was cloned and sequenced to identify the transcriptional start site (TSS). The promoter region upstream of the TSS did not contain the core promoter sequence in the typical positions indicating this gene may not use a standard core promoter. Other sequence motifs associated with tissue specific expression and phytohormone response were present. Reverse transcription (RT)-PCR with gene specific primers identified the sites of expression of this gene. Expression was most abundant in the meristem region, and immature stem and relatively lower in starch accumulating roots demonstrating that this gene has a different pattern of expression than the previously reported cotton ADPGp small subunit gene. Additionally this gene was differentially expressed in cotton fibers. The presence of starch was confirmed in developing cotton fibers suggesting that starch metabolism plays a role in cotton fiber development.

AB Fusarium yellows, caused by the soil-borne fungus Fusarium oxysporum f. sp. betae (Fob), can lead to significant yield losses in sugar beet. This fungus is variable in pathogenicity, morphology, host range and symptom production, and is not a well characterized pathogen on sugar beet. From 1998 to 2003, 86 isolates of F. oxysporum and 20 other Fusarium species from sugar beet, along with four F. oxysporum isolates from dry bean and five from spinach, were obtained from diseased plants and characterized for pathogenicity to sugar beet. A group of sugar beet Fusarium isolates from different geographic areas (including nonpathogenic and pathogenic F. oxysporum, F. solani, F. proliferatum and F. avenaceum), F. oxysporum from dry bean and spinach, and Fusarium DNA from Europe were chosen for phylogenetic analysis. Sequence data from beta- tubulin, EF1 alpha and ITS DNA were used to examine whether Fusarium diversity is related to geographic origin and pathogenicity. Parsimony and Bayesian MCMC analyses of individual and combined datasets revealed no clades based on geographic origin and a single clade consisting exclusively of pathogens. The presence of FOB and nonpathogenic isolates in clades predominately made up of Fusarium species from sugar beet and other hosts indicates that F. oxysporum f. sp. betae is not monophyletic.

AB This paper presents a new drought assessment method by spatially and temporally integrating temperature vegetation dryness index (TVDI) with regional water stress index (RWSI) based on a synergistic approach. With the aid of LANDSAT TM/ETM data, we were able to retrieve the land-use and land-cover (LULC), vegetation indices (VIs), and land surface temperature (LST), leading to the derivation of three types of modified TVDI including TVDI_SAVI, TVDI_ANDVI and TVDI_MSAVI, for drought assessment in a fast growing coastal area, Northern China. The categorical classification of four drought impact levels associated with the RWSI values enables us to refine the spatiotemporal relationship between the LST and the VIs. Holistic drought impact assessment between 1987 and 2000 was carried out by linking RWSI with TVDIs group wise. Research findings indicate that: (1) LST and VIs were negatively correlated in most cases of low, medium, and high vegetation cover except the case of high density vegetation cover in 2000 due to the effect of urban heat island (UHI) effect; (2) the shortage of water in 1987 was more salient than that that in 2000 based on all indices of TVDI and RWSI; and (3) TVDIs are more suitable for monitoring mild drought, normal and wet conditions when RWSI is smaller than 0.752; but they are not suitable for monitoring moderate and severe drought conditions.

AB Sixty-nine endospore-forming bacterial endophytes consisting of 15 different species from five genera were isolated from leaves, pods, branches, and flower cushions of Theobroma cacao as potential biological control agents. Sixteen isolates had in vitro chitinase production. In antagonism studies against cacao pathogens, 42% inhibited Moniliophthora roreri, 33% inhibited Moniliophthora perniciosa, and 49% inhibited Phytophthora capsici. Twenty-five percent of isolates inhibited the growth of both Moniliophthora spp., while 22% of isolates inhibited the growth of all three pathogens. Isolates that were chitinolytic and tested negative on Bacillus cereus agar were tested with in planta studies. All 14 isolates colonized the phyllosphere and internal leaf tissue when introduced with Silwet L-77, regardless of the tissue of origin of the isolate. Eight isolates significantly inhibited P. capsici lesion formation (p = 0.05) in detached leaf assays when compared to untreated control leaves. ARISA with bacilli specific primers amplified 21 OTUs in field grown cacao leaves, while eubacteria specific primers amplified 58 OTUs. ARISA analysis of treated leaves demonstrated that inundative application of a single bacterial species did not cause a long-term shift of native bacterial communities.

AB Gas exchange and water relations were evaluated under full-season in situ infrared (IR) warming for hard red spring wheat (Triticum aestivum L. cv. Yecora Rojo) grown in an open field in a semiarid desert region of the southwest USA. A temperature free-air controlled enhancement (T-FACE) apparatus utilizing IR heaters maintained canopy air temperature above 3.0 m Heated plots of wheat by 1.3 and 2.7 degrees C (0.2 and 0.3 degrees C below the targeted set-points of Reference plots with dummy heaters) during daytime and nighttime, respectively. Control plots had no apparatus. Every 6 weeks during 2007-2009 wheat was sown under the three warming treatments (i.e., Control, Heated, Reference) in three replicates in a 3 x 3 Latin square (LSQ) design on six plantings during 4 months (i.e., January, March, September, December), or in a natural temperature variation treatment (i.e., Control) in three replicates in a randomized complete block (RCB) design on nine plantings during 7 months (i.e., January, February, April, June, July, August, October). Soil temperature (T-s) and volumetric soil-water content (theta(s)) were 1.3 degrees C warmer and 14% lower in Heated compared with Reference plots, respectively. Other than a 1% shading effect, no artifacts on gas exchange or water relations were associated with the IR warming apparatus. IR warming increased carbon gain characteristic of an increase in metabolic rates to higher temperature that may have been attributed to the well-watered wheat crop and the supplemental irrigation that minimized plant-to-air water vapor pressure differences between IR-warmed and nonwarmed plots. Nevertheless, seasonal oscillations in the IR warming response on carbon gain occurred. IR warming decreased leaf water status and provided thermal protection during freeze events. IR warming is an effective experimental methodology to investigate the impact of global climate change on agronomic cropping and natural ecosystems to a wide range of natural and artificially imposed air temperatures.

AB This study was undertaken to determine how seed isoflavones from soybean [Glycine max (L.) Merr.] lines differing in their maturity group, change between locations and years with different weather conditions. Seeds from 15 lines representing four maturity groups grown at three locations in Maryland (full season at all three and double crop at one location) were analyzed from 2001 to 2002, representing one relatively normal and one warm and dry year, respectively. Comparing lines, total isoflavones averaged for both years and all locations/planting dates ranged between 4.7 mu mol [g seed dry matter (SDM)](-1) in MD95-5358 and 8.7 mu mol (g SDM)(-1) in Stressland. Isoflavones were reduced by about 50% in early maturing soybean lines in 2002 compared to 2001 under warmer conditions on the Eastern Shore of Maryland but not in the cooler central Maryland location. Isoflavones were not affected consistently or to a large extent in later maturity lines at any location or planting date combination. Relative changes in genistein, daidzein, and total isoflavones were similar to each other, whereas glycitein was much more variable. The results suggest that early maturing soybean lines are more likely to be affected by changes in temperature and precipitation.

AB Grapefruit (Citrus x paradisi) develop symptoms of chilling injury (CI) if held at temperatures below about 10 degrees C. Conditioning grapefruit at a low, but non-chilling (16 degrees C) temperature prior to storage at a chilling temperature reduces the development of Cl symptoms. Changes in transcript abundance for a number of genes have been correlated with chilling stress in citrus fruit. We tested the hypothesis that conditioning affects transcript abundance of genes related to chilling stress in grapefruit. Grapefruit were harvested from a commercial grove in Florida in September and divided into two groups; one group was placed immediately at 5 degrees C (non-conditioned, NC); the second group was placed at 16 degrees C for 1 week (conditioned. C) and then transferred to 5 degrees C. Symptoms of Cl were visible on NC and C fruit following 14 d at 5 degrees C, but were consistently more severe on NC than C fruit. Storage at 5 degrees C caused increases in abundance of transcripts for 1-aminocyclopropane-1-carboxylate oxidase (ACO), galactinol synthase, a chilling-induced oxygenase, and a temperature-induced lipocalin, consistent with previous reports. Levels of these transcripts were lower in C than in NC fruit during storage at 5 degrees C, but this pattern did not persist following transfer to 20 degrees C. Levels of transcripts for catalase, a metallothionein-like protein, a lipid transfer protein, a stress-responsive zinc finger protein, and a citrus low temperature inducible protein were consistently higher in C than NC fruit during storage at 5 degrees C. Our results show that conditioning increases chilling tolerance in grapefruit and demonstrates that abundance of transcripts of a number of genes related to chilling stress is affected by conditioning. This suggests a potential quantitative relationship between gene expression and conditioning induced chilling tolerance. We cannot say, however, that these changes are related to chilling tolerance per se; they may only reflect the difference between chilling-sensitive and chilling-tolerant fruit.

AB Two primary ways to achieve low-cost, nutritionally efficacious diets for sunshine bass (Morone chrysops x M. saxatilis) are to decrease crude protein (CP) levels and the use alternative animal or plant ingredients to partially, or totally, replace fish meal. A 459-day feeding trial was conducted with juvenile (35 g) sunshine bass to evaluate growth, feed efficiency, size distribution at harvest, immune function status and body composition when fed diets containing soybean meal (SBM), feed-grade poultry by-product meal (PBM), and supplemental methionine as complete replacements for menhaden fish meal (MFM) at 300 g kg(-1) diet, while simultaneously reducing dietary crude protein (CP; 320, 360, and 400 g kg(-1)). The feeding trial was conducted in 12, 0.04-ha earthen ponds stocked at a rate of 300 per pond (3000/ac). At 400 g kg(-1) dietary protein, there were no differences in responses between fish fed the diet containing MFM or the diet in which MFM was completely replaced with PBM and supplemental methionine on a digestible protein basis. However, final mean weight, percentage weight gain, specific growth rate, and protein efficiency ratio were linearly related (P < 0.10) to dietary protein level in the diets while no significant differences were found in feed intake and feed conversion ratio. The expected odds of fish at harvest being classified into larger size categories (> 680 g) decreased as dietary protein level decreased based on ordinal logistic regression. There were no significant relationships between body compositional indices and dietary treatments. Body fat ranged from 56 g kg(-1) to 62 g kg(-1), single fillets ranged from 28% to 30%, and livers ranged from 2.45% to 2.62% of body weight across treatments. Fillet protein concentration was positively linear and quadratic for protein level in the diet but fillet moisture, lipid and ash did not differ among diets. Total serum protein, immunoglobulin and lysozyme activity decreased linearly with decreasing diet protein level. These results suggest that complete replacement of MFM with feed grade PBM and supplemental methionine is possible in diets for sunshine bass and that further reductions in dietary protein level may be possible with amino acid supplementation.

AB A new species of gall midge, Chilophaga virgati Gagn, (Diptera: Cecidomyiidae), collected from tillers of switchgrass at Brookings, South Dakota (44.31134A degrees N, 96.78374A degrees W) is described here. Plant morphological symptoms of infestation and frequency of tillers infested are also provided. Full-grown larvae of C. virgati were found inside the sheath of the flag leaf of reproductive tillers of clonally replicated spaced plants of a selected southern upland population of switchgrass during October 2008 and 2009. Infested tillers were shorter and lighter than normal tillers and had panicles that were partially encased in the sheath of the flag leaf due to reduced elongation of the peduncle as a result of the feeding of larvae of C. virgati at the proximal end of the panicle and in the intercalary meristem area of the peduncle. Variation was found among 10 genotypes for percentage of tillers infested by C. virgati, with a range from 7.2% to 21.8%. No difference was found between years for infestation rate (12.7% in 2008 and 14.3% in 2009). The mass of infested tillers was 35% that of normal tillers, and infested tillers produced no appreciable amount of viable seeds. Results of this research revealed that C. virgati had direct negative impacts on biomass and seed production in spaced plant nurseries of switchgrass. C. virgati was also observed in seeded swards of northern upland switchgrass cultivars, but its impact in seeded swards has not yet been determined.

AB Quantifying actual and theoretical ethanol yields from biomass conversion processes such as simultanteous saccharification and fermentation (SSF) requires expensive, complex fermentation assays, and extensive compositional analyses of the biomass sample. Near-infrared reflectance spectroscopy (NIRS) is a non-destructive technology that can be used to obtain rapid, low-cost, high-throughput, and accurate estimates of agricultural product composition. In this study, broad-based NIRS calibrations were developed for switchgrass biomass that can be used to estimate over 20 components including cell wall and soluble sugars and also ethanol production and pentose sugars released as measured using a laboratory SSF procedure. With this information, an additional 13 complex feedstock traits can be determined including theoretical and actual ethanol yields from hexose fermentation. The NIRS calibrations were used to estimate feedstock composition and conversion information for biomass samples from a multi-year switchgrass (Panicum virgatum L.) biomass cultivar evaluation trial. There were significant differences among switchgrass strains for all biomass conversion and composition traits including actual ethanol yields, ETOHL (L Mg(-1)) and theoretical ethanol yields, ETOHTL (L Mg(-1)), based on cell wall and non-cell wall composition NIRS analyses. ETOHL means ranged from 98 to 115 L Mg(-1) while ETOHTL means ranged from 203 to 222 L Mg(-1). Because of differences in both biomass yields and conversion efficiency, there were significant differences among strains for both actual (2,534-3,720 L ha(-1)) and theoretical (4,878-7,888 L ha(-1)) ethanol production per hectare. It should be feasible to improve ethanol yields per hectare by improving both biomass yield and conversion efficiency by using NIRS analyses to quantify differences among cultivars and management practices.

AB Lignin content of switchgrass (Panicum virgatum L.), a bioenergy species, is a critical determinant of biomass quality since it can negatively impact conversion of biomass into liquid fuels via biochemical platforms. Cinnamyl alcohol dehydrogenase (CAD) is a key enzyme in lignin biosynthesis. Here, we have shown that cv. Kanlow switchgrass contains at least two closely related CAD genes (PviCAD1 and PviCAD2) that code for proteins containing highly conserved domains and residues that identify them as bona fide CADs. Both recombinant proteins displayed substrate kinetics consistent with their presumed role in cell wall lignification. Proteomic and immunoblotting detected CAD containing spots in internode protein extracts, and proteomic analyses demonstrated that both CADs were expressed. In planta CAD activity, CAD protein levels were observed at all stages of tiller development. A real-time qPCR analysis of the two CADs and one CAD-like sequence indicated that transcripts coding for PviCAD1 were present in greater abundance than those coding for PviCAD2. Transcripts for a third CAD-like sequence (PviAroADH) were present at intermediate levels as compared to PviCAD1 and CAD2. The predicted protein sequence of PviAroADH indicated that it was an enzyme unrelated to lignification based on phylogenetic and protein modeling data.

TI Evaluating the effects of alternative forest management plans under

AB Using historical General Land Office record as a reference, this study employed a landscape-scale disturbance and succession model to estimate the future cumulative effects of six alternative management plans on the tree species composition for various physiographic settings for the Mark Twain National Forest in Missouri. The results indicate that over a 200-year horizon, the relative abundance of black oak and pine species groups will decrease and the relative abundance of the white oak species group will increase, regardless of management strategy. General Land Office witness tree records provide a measure of tree species composition in the period from 1800 to 1850, prior to the large-scale influx of European settlers. Compared to the tree species composition described in the General Land Office records, the six contemporary management alternatives considered all would lead to a lower abundance of pine species, a higher abundance of red/black oak species, and a slightly higher abundance of white oak species after 200 years.
Impacts of management on tree species composition varied with physiographic settings. The projected relative abundance of pine differed significantly across the five physiographic classes over the first 40 years of the simulation. In the medium term (simulation years 41-100) the projected relative pine abundance differed significantly among only four physiographic classes. In the long term (simulation years 100-200) the projected relative pine abundance differed for only one physiographic class. In contrast, differences among physiographic classes in the relative abundance of black oaks and white oaks increased over time. In general, the expected long-term differences in relative tree species abundance among six proposed alternative management plans are small compared to shifts in tree species composition that have occurred from 1850 to the present.

AB Due to outbreaks of salmonellosis associated with whole raw almonds, an infrared (IR) pasteurization process was investigated for its efficacy in improving the safety of raw almonds. After almonds were heated to 100, 110 and 120 degrees C with IR, they were cooled at ambient temperature to a holding temperature of 70, 80 or 90 degrees C before being transferred to a custom-designed holding device for different time periods up to 60 min. We observed that holding almonds at 90 degrees C for 10-15 min reduced the Pediococcus population size by more than 5-log and holding at 80 degrees C for longer than 22 min provided more than 4-log reduction, thus satisfying the targeted 4-log reduction required in the almond industry. The L*a*b* color values of whole almonds were not affected significantly (P > 0.05) by the IR process whereas the a* and b* color values of ground almonds changed significantly (P < 0.05). The sensory panel did not detect any significant difference (P > 0.01) in appearance, texture, flavor and overall quality of pasteurized almonds compared with untreated samples.

AB Deficit irrigation is an optimization strategy for achieving sustainability of irrigated crop production. A field-study of cotton (Gossypium hirsutum L.) response to a limited water supply was conducted in an Alfisol in the southern High Plains of Texas. The objectives were to investigate cotton N uptake, canopy temperature, plant spectral index and lint yield variation under deficit irrigation and to provide information for enhancing sustainability of the water resources and Alfisols in the semi-arid environment. The experimental treatments were two deficit-irrigation levels at 50% and 75% of cotton evapotranspiration (ET). Plant and soil variables were measured 15 m apart along the center-pivot irrigation circles. The results show that cotton plants under the 50%-ET deficit irrigation level were 21% more water stressed (P < 0.05) based on the reflectance water index ratio. The 50%-ET irrigation resulted in a 25% lint yield loss with a 33% water saving compared to the higher irrigation level (75%-ET). Plant reflectance, canopy temperature, total N uptake and lint yield were correlated with normalized difference vegetative index (NDVI), soil water content (SWC), soil NO(3)-N concentrations and elevation (-0.69 < r < 0.72, P < 0.05, respectively). Future cotton lint yield is weighted on NDVI and water variation, quantified in a multivariate autoregressive state-space model. Increases in plant reflectance in the water band are signs of early plant water stress. Compared to the 12-year regional cotton lint yield obtained with full irrigation, the 75%-ET deficit irrigation would be agronomical, economical efficient in Alfisoils with only 7.8% of lint-yield loss from water stress but 25% of water saving for sustainable water use.

AB The Urban Forest Effects-Deposition model (UFORE-D) was developed with a component-based modeling approach. Functions of the model were separated into components that are responsible for user interface, data input/output, and core model functions. Taking advantage of the component-based approach, three UFORE-D applications were developed: a base application to estimate dry deposition at an hourly time step, and two sensitivity analyses based on Monte Carlo simulations with a Latin hypercube sampling (LHS-MC) and a Morris one-at-a-time (MOAT) sensitivity test. With the base application, dry deposition of CO, NO2, O-3, PM10, and SO2 in the city of Baltimore was estimated for 2005. The sensitivity applications were performed to examine UFORE-D model parameter sensitivity. In general, dry deposition velocity was sensitive to temperature and leaf area index (LAI). Temperature had a non-linear effect on all pollutants, while LAI was important to NO2 deposition with a nearly linear effect. PAR and wind speed had limited effects on dry deposition of all pollutants; dry deposition was affected by PAR and wind speed only up to their threshold values. The component-based approach allows for seamless integration of new model elements, and provides model developers with a platform to easily interchange model components. (C) 2010 Elsevier Ltd.

AB Heterocyclic amines (HCAs) are produced in meats cooked at high temperature, which are potent mutagens and a risk factor for human cancers. The aim of this study was to estimate the amount of HCAs in some commonly consumed ready-to-eat (RTE) meat products. The RTE products were purchased from a local grocery store, and HCA were analyzed using an analytical method based on solid-phase extraction followed by HPLC. The primary HCAs in these samples were PhIP (2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine) (not detected-7.9 ng/g) and MelQx (2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline) (not detected-3.6 ng/g). Products ranked in order of increasing total HCA content: pepperoni (0.05 ng/g) < hot dogs and deli meat products (0.5 ng/g) < fully cooked bacon (1.1 ng/g) < rotisserie chicken meat (1.9 ng/g) < rotisserie chicken skin (163 ng/g). We believed that cooking conditions and ingredients influenced the level of HCAs in these RTE products and concluded that consumption of RTE meat products contributes very little to HCA intake. Results from this study can be used in risk assessment study to estimate human exposure to HCAs due to food consumption. (C) 2010 Elsevier Ltd. All rights reserved.

AB Germin-like proteins (GLPs) play diversified roles in plant development and defense response. Here, we identified 36 expressed sequence tags (ESTs) encoding GLPs from peanut (Arachis hypogaea L.). After assembly, these ESTs were integrated into eight unigenes named AhGLP1 to AhGLP8, of which, three (AhGLP1-3) were comprised 14, ten, and seven EST clones, respectively, whereas the remaining ones were associated with one single clone. The length of the deduced amino acid (AA) residues ranged from 208 to 223 AAs except for AhGLP6 and AhGLP8, which were incomplete at the carboxyl terminus. All of the AhGLPs contained a possible N-terminal signal peptide that was 17 to 24 residues in length excluding AhGLP7, where there is likely a non-cleavable amino terminus. Phylogenetic analysis showed that these AhGLPs were classified into three subfamilies. Southern blot analysis indicated that AhGLP1 and AhGLP2 likely have multiple copies in the peanut genome. The recombinant mature AhGLP1 and AhGLP2 proteins were successfully expressed in Escherichia coli. The purified AhGLP2 has superoxide dismutase (SOD) activity in enzymatic assay, but not oxalate oxidase activity. The SOD activity of AhGLP2 was stable up to 70A degrees C and resistant to hydrogen peroxide, suggesting that AhGLP2 might be a manganese-containing SOD. Furthermore, AhGLP2 could confer E. coli resistance to oxidative damage caused by paraquat, suggesting that the AhGLP2 likely protects peanut plants from reactive oxygen metabolites. Thus, information provided in this study indicates the diverse nature of the peanut GLP family and suggests that some of AhGLPs might be involved in plant defense response.

AB In this study the daily dietary Selenium (Se) intake in Suzhou was investigated to determine whether residents in such a developed region were susceptible to moderate Se deficiency. Concentrations of Se in typically consumed foods in Suzhou were determined. Based on food Se content and the daily per capita consumption, the estimated Se intake in Suzhou was 43.9 +/- 3.8 mu g day(-1). The results revealed that pork and cereals were the major sources of Se daily intake and contributed 24.7% and 22.6% to the daily Se intake, respectively. The Se content in hair of local residents was 389.9 +/- 103.6 mu g kg(-1) for male and 322.9 +/- 101.8 mu g kg(-1) for female. A significant linear correlation between the daily Se intake and the hair Se concentration was established. The hair Se concentration could be used to bioindicate the level of Se intake for longer period. (C) 2010 Elsevier Ltd. All rights reserved.

In this study, a simple, rapid, and efficient ultra-performance liquid chromatography (UPLC) method combined with diode array detector (DAD) and mass spectroscopic (MS) detection and chemometrics analysis was used to analyse three different types of teas (green pu-erh, green tea, white tea). Using the developed method, 68 compounds were identified and 54 were quantified based on retention times. UV spectra, and MS spectra by referencing to available standards and data in the literatures. The results showed the chemical differences between the tested teas. Principal component analysis (PCA) was applied to classify and distinguish between tea samples. Published by Elsevier Ltd.

TI The development and characterization of a 60K SNP chip for chicken
SO BMC GENOMICS
LA English
DT Article
ID GENOTYPING ASSAY; GENOME; POLYMORPHISM; ARRAY; MAP
AB Background: In livestock species like the chicken, high throughput single nucleotide polymorphism (SNP) genotyping assays are increasingly being used for whole genome association studies and as a tool in breeding (referred to as genomic selection). To be of value in a wide variety of breeds and populations, the success rate of the SNP genotyping assay, the distribution of the SNP across the genome and the minor allele frequencies (MAF) of the SNPs used are extremely important.
Results: We describe the design of a moderate density (60k) Illumina SNP BeadChip in chicken consisting of SNPs known to be segregating at high to medium minor allele frequencies (MAF) in the two major types of commercial chicken (broilers and layers). This was achieved by the identification of 352,303 SNPs with moderate to high MAF in 2 broilers and 2 layer lines using Illumina sequencing on reduced representation libraries. To further increase the utility of the chip, we also identified SNPs on sequences currently not covered by the chicken genome assembly (Gallus_gallus-2.1). This was achieved by 454 sequencing of the chicken genome at a depth of 12x and the identification of SNPs on 454-derived contigs not covered by the current chicken genome assembly. In total we added 790 SNPs that mapped to 454-derived contigs as well as 421 SNPs with a position on Chr_random of the current assembly. The SNP chip contains 57,636 SNPs of which 54,293 could be genotyped and were shown to be segregating in chicken populations. Our SNP identification procedure appeared to be highly reliable and the overall validation rate of the SNPs on the chip was 94%. We were able to map 328 SNPs derived from the 454 sequence contigs on the chicken genome. The majority of these SNPs map to chromosomes that are already represented in genome build Gallus_gallus-2.1.0. Twenty-eight SNPs were used to construct two new linkage groups most likely representing two micro-chromosomes not covered by the current genome assembly.
Conclusions: The high success rate of the SNPs on the Illumina chicken 60K Beadchip emphasizes the power of Next generation sequence (NGS) technology for the SNP identification and selection step. The identification of SNPs from sequence contigs derived from NGS sequencing resulted in improved coverage of the chicken genome and the construction of two new linkage groups most likely representing two chicken micro-chromosomes.

AB Rust fungi are some of the most devastating pathogens of crop plants. They are obligate biotrophs, which extract nutrients only from living plant tissues and cannot grow apart from their hosts. Their lifestyle has slowed the dissection of molecular mechanisms underlying host invasion and avoidance or suppression of plant innate immunity. We sequenced the 101-Mb genome of Melampsora larici-populina, the causal agent of poplar leaf rust, and the 89-Mb genome of Puccinia graminis f. sp. tritici, the causal agent of wheat and barley stem rust. We then compared the 16,399 predicted proteins of M. larici-populina with the 17,773 predicted proteins of P. graminis f. sp tritici. Genomic features related to their obligate biotrophic lifestyle include expanded lineage-specific gene families, a large repertoire of effector-like small secreted proteins, impaired nitrogen and sulfur assimilation pathways, and expanded families of amino acid and oligopeptide membrane transporters. The dramatic up-regulation of transcripts coding for small secreted proteins, secreted hydrolytic enzymes, and transporters in planta suggests that they play a role in host infection and nutrient acquisition. Some of these genomic hallmarks are mirrored in the genomes of other microbial eukaryotes that have independently evolved to infect plants, indicating convergent adaptation to a biotrophic existence inside plant cells.

AB In this study, we compared the morphology of Sarcocystis sinensis and Sarcocystis hominis, and assessed the infectiousness of S. sinensis for human volunteers. The cysts of S. sinensis were from water buffalo (Bubalus bubalis) and those of S. hominis were from cattle (Bos taurus). Transmission electron microscopy of S. sinensis cysts revealed that the cyst wall had leaning, finger-like protrusions measuring 1.44-5.08 mu m in length and without invaginations on the tip surface of the protrusions. In contrast, the cyst wall of S. hominis had upright, finger-like protrusions measuring 9.43 mu m x 2.42 mu m and with vesicle-like invaginations on the tip surface of the protrusions. Scanning electron microscopy revealed that surface of the protrusions was arranged as rectangles in S. sinensis, as compared to tongue-shaped in S. hominis. Other distinguishing features of S. sinensis include a thin ground substrate (GS) zone with microtubules and small, circle-like structures located at the base of the protrusions. Human volunteers, after consuming S. sinensis cysts, produced no sporocysts or oocysts in feces, suggesting that humans could not serve as definitive hosts for S. sinensis. By contrast, many sporocysts and oocysts were passed in feces of a human volunteer 11-29 days after ingestion of S. hominis cysts. These results showed that S. sinensis and S. hominis are separate species and S. sinensis cannot use human being as the definitive host. (c) 2010 Elsevier B.V. All rights reserved.

AB Effect of sericea lespedeza [SL; Lespedeza cuneata (Dum-Cours.) G. Don.] leaf meal feeding was evaluated in two experiments in indoor reared goats with experimental infection of Haemonchus contortus larvae. In the first experiment, ten 8-10 month old male Spanish and Alpine cross kids pair matched for body weight and age were fed SL or bermudagrass [BG; Cynodon dactylon (L) Pers.] hay one week before infection and were infected with 5000 H. contortus L(3). The animals were maintained on the same diet for the remaining period and were slaughtered 28 days post-infection (DPI) to determine the establishment of incoming infective larvae. Goats fed SL had lower establishment (P < 0.05) of H. contortus larvae than that of the control goats fed BG hay. In the second experiment, twenty-five 8-10 months old male Alpine cross, Saanen, Nubian x Saanen and Spanish kids reared in confinement on BG were experimentally infected with 5000 H. contortus L(3). On 35 DPI, the animals were allocated to two groups after blocking by fecal egg count (FEC), and one group was fed SL leaf meal (n = 13), and another control group remained on BG (n = 12). Four goats/group were slaughtered successively on days 7, 14, and 28 days post SL feeding, except on day 7, when five SL fed goats were slaughtered. Fecal egg counts and blood packed cell volume (PCV) were measured at weekly intervals and worm count, female worm fecundity, worm length and mucosal eosinophils, mast cells and globule leucocytes were measured after slaughter. Goats fed SL had a lower FEC (P < 0.05) one week after feeding, as compared to those fed on BG, and the values remained at low level thereafter. Similarly. PCV was also significantly affected by feeding (P < 0.01), and feeding and time interaction (P < 0.05). However, worm burden, female worm fecundity, parasite length, and mucosal inflammatory cell count were similar between the groups. Feeding SL reduced the establishment of infective larvae and FEC of H. contortus in experimental studies and this plant could be used for biological control of parasite infection under field conditions to limit the harmful effects of the parasites in goats.

AB The highly weathered, low-carbon, intensively cropped, drought-prone Coastal Plain soils of Georgia are susceptible to runoff and soil loss, especially at certain times of the year when soil water contents are elevated. We quantified the effects of antecedent water content (AWC) on runoff (R) and sediment (E) losses from two loamy sands managed under conventional- (CT), strip- (ST), and/or no-till (NT) systems. Two AWC treatments were evaluated: field moist (FM) and pre-wet (PW), created with and without post pesticide application irrigations (similar to 12 mm of water added with the rainfall simulated over 30 min) for incorporation. Treatments (5) evaluated were: CT + FM, CT + PW, ST + FM, ST + PW, and NT + PW. Field plots, each 2-m x -3 m, were established on each treatment. Each 6-m(2) field plot received simulated rainfall at a variable rainfall intensity (I-v) pattern for 70 min (site 1) or a constant rainfall intensity (I-c) pattern for 60 min (site 2; I-c = 50.8 mm h(-1)). Adding similar to 12 mm of water as herbicide incorporation increased AWCs of the 0-2 (3-9-fold) and 2-15 (23-117%) cm soil depths of PW plots compared to existing field moist soil conditions. Increase in AWC increased R (as much as 60%) and maximum R rates (as much as 62%), and decreased E (at least 59%) and maximum E rates (as much as 2.1-fold) for corresponding tillage treatments. Compared to CT plots, ST and NT plots decreased R (at least 2.6-fold) and maximum R rates (as much as 3-fold), and decreased E (at least 2.7-fold) and maximum E rates (at least 3.2-fold). Runoff curves for pre-wetted CT and ST plots were always higher than corresponding FM curves, whereas E curves for field moist CT and ST plots were always higher than corresponding PW curves. Changes in AWC and tillage affected detachment and transport processes controlling runoff and sediment yields. A more accurate measure of rainfall partitioning and detachment and transport processes affecting R and E losses was obtained when commonly occurring field conditions (increased AWC with irrigation; I-v pattern derived from natural rainfall; commonly used tillage systems) were created and evaluated.

AB Tile drainage is a common water management practice in many agricultural landscapes in the Midwestern United States. Drainage ditches regularly receive water from agricultural fields through these tile drains. This field-scale study was conducted to determine the impact of tile discharge on ambient nutrient concentration, nutrient retention and transport in drainage ditches. Grab water samples were collected during three flow regimes for the determination of soluble phosphorus (SP), ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3-N) concentrations and their retention in three drainage ditches. Measured nutrient concentration indicated lower SP and NH4+-N, and greater NO3-N concentrations in tile effluents compared to the ditch water. Net uptake lengths were relatively long, especially for NO3-N, indicating that nutrients were generally not assimilated efficiently in these drainage systems. Results also indicated that the study reaches were very dynamic showing alternating increases or decreases in nutrient concentration across the flow regimes. The drainage ditches appeared to be nutrient-rich streams that could potentially influence the quality of downstream waters. (C) 2011 Elsevier B.V. All rights reserved.

AB Aldehyde dehydrogenase 2 (ALDH2) catalyzes oxidation of toxic aldehydes to carboxylic acids. Physiologic levels of Mg(2+) ions influence ALDH2 activity in part by increasing NADH binding affinity. Traditional fluorescence measurements monitor the blue shift of the NADH fluorescence spectrum to study ALDH2-NADH interactions. By using time-resolved fluorescence spectroscopy, we have resolved the fluorescent lifetimes (tau) of free NADH (tau = 0.4 ns) and bound NADH (tau = 6.0 ns). We used this technique to investigate the effects of Mg(2+) on the ALDH2-NADH binding characteristics and enzyme catalysis. From the resolved free and bound NADH fluorescence signatures, the K(D) for NADH with ALDH2 ranged from 468 to 12 mu M for Mg(2+) ion concentrations of 20 to 6000 mu M, respectively. The rate constant for dissociation of the enzyme-NADH complex ranged from 0.4s(-1) (6000 mu M Mg(2+)) to 8.3 s(-1) (0 mu M Mg(2+)) as determined by addition of excess NAD(+) to prevent re-association of NADH and resolving the real-time NADH fluorescence signal. The apparent NADH association/re-association rate constants were approximately 0.04 mu M(-1) s(-1) over the entire Mg(2+) ion concentration range and demonstrate that Mg(2+) ions slow the release of NADH from the enzyme rather than promoting its re-association. We applied NADH fluorescence lifetime analysis to the study of NADH binding during enzyme catalysis. Our fluorescence lifetime analysis confirmed complex behavior of the enzyme activity as a function of Mg(2+) concentration. Importantly, we observed no pre-steady state burst of NADH formation. Furthermore, we observed distinct fluorescence signatures from multiple ALDH2-NADH complexes corresponding to free NADH, enzyme-bound NADH, and, potentially, an abortive NADH-enzyme-propanal complex (tau = 11.2 ns).

AB Phosphorus (P) fractionation and distribution in sediments are of great concern in the Florida Everglades ecosystem because potential eutrophication of surface waters usually results from P external loading and stability. Intact core sediment samples were collected to a depth of 35 cm from wetlands and canals across Water Conservation Area 3 (WCA-3) of the Florida Everglades. These sediment cores were sliced into 5 cm increments and analyzed for P contents in different fractions by sequential extraction. These fractions mainly included total P (TP), readily available P (Pi-KCl), Fe/Al-bound P (Pi-NaOH), Ca/Mg-bound P (Pi-HCl), organic P (Po-NaOH), and residual P (Po-Residue). Results showed that the canal sediments had the highest concentrations of TP, with about 87% in the form of Ca/Mg-bound fraction, and the concentrations of TP in these sediments increased with depth. In contrast, the wetland sediments contained the lowest concentrations of TP (predominantly in the organic fraction), with 43% residual P and 27% Po-NaOH, and the concentrations of TP in these sediments decreased with depth. In addition, a large amount of the readily available P (up to 1500 mg kg(-1)) in the canal sediments was accumulated at the top layer of 0-5 cm. This study suggests that any disturbance and/or environmental alterations, such as high canal flow and dredging in canal sediments, could pose a potential risk of a P increase in the water column and, consequently, in the wetlands because of the release of readily available P despite the relatively stable nature of such P fractions in these sediments.

AB A 14-step biomimetic synthetic route to glyceollin I (1.5% overall yield) was developed and deployed to produce the natural enantiomeric form in soy, its unnatural stereoisomer, and a racemic mixture. Enantiomeric excess was assessed by asymmetric NMR shift reagents and chiral HPLC. Antiproliferative effects were measured in human breast, ovarian, and prostate cancer cell lines, with all three chiral forms exhibiting growth inhibition (GI) in the low to mid mu M range for all cells. The natural enantiomer, and in some cases the racemate, gave significantly greater GI than the unnatural stereoisomer for estrogen receptor positive (ER+) versus ER- breast/ovarian cell lines as well as for androgen receptor positive (AR(+)) versus AR(-) prostate cancer cells. Surprisingly, differences between ER+ and ER- cell lines were not altered by media estrogen conditions. These results suggest the antiproliferative mechanism of glyceollin I stereoisomers may be more complicated than strictly ER interactions.

AB Urban reforestation in China has led to increasing debate about the impact of urban trees and forests on water resources. Although transpiration is the largest water flux leaving terrestrial ecosystems, little is known regarding whole tree transpiration in urban environments. In this study, we quantified urban tree transpiration at various temporal scales and examined the biophysical control of the transpiration pattern under different water conditions to understand how trees survive in an urban environment. Concurrent with microclimate and soil moisture measurements, transpiration from Cedrus deodara(Roxb)Loud., Zelkova schneideriana Hend.-Mazz.. Euonymus bungeanus Maxim., and Metasequoia glyptostroboides Hu et cheng was measured over a 2-year period using thermal dissipation probe (TDP) techniques. The average monthly transpiration rates reached 12.78 +/- 0.73 (S.E.) mm, 1.79 +/- 0.16 mm, 10.18 +/- 0.55 mm and 19.28 +/- 2.24 mm for C. deodara, Z.schneideriana. E. bungeanus and M. glyptostroboides, respectively. Transpiration rates from M. glyptostroboides reported here may need further study as this species showed much higher sap flows and greater transpiration fluctuation under different environmental conditions than other species. Because of deep soil moisture supply, summer dry spells did not reduce transpiration rates even when tree transpiration exceeded rainfall. While vapor pressure deficit (VPD) was the dominant environmental factor on transpiration, trees controlled canopy conductance effectively to limit transpiration in times of water stress. Our results provide evidence that urban trees could adopt strong physiological control over transpiration under high evaporative demands to avoid dehydration and can make use of water in deeper soil layers to survive summer dry spells. Moreover, urban trees have the ability to make the best use of precipitation when it is limited, and are sensitive to soil and air dryness. (C) 2011 Elsevier B.V. All rights reserved.

AB Research activities focused on estimating the direct emissions of carbon from wildland fires across North America are reviewed as part of the North American Carbon Program disturbance synthesis. A comparison of methods to estimate the loss of carbon from the terrestrial biosphere to the atmosphere from wildland fires is presented. Published studies on emissions from recent and historic time periods and five specific cases are summarized, and new emissions estimates are made using contemporary methods for a set of specific fire events. Results from as many as six terrestrial models are compared. We find that methods generally produce similar results within each case, but estimates vary based on site location, vegetation ( fuel) type, and fire weather. Area normalized emissions range from 0.23 kg C m(-2) for shrubland sites in southern California/NW Mexico to as high as 6.0 kg Cm-2 in northern conifer forests. Total emissions range from 0.23 to 1.6 Tg C for a set of 2003 fires in chaparral-dominated landscapes of California to 3.9 to 6.2 Tg C in the dense conifer forests of western Oregon. While the results from models do not always agree, variations can be attributed to differences in model assumptions and methods, including the treatment of canopy consumption and methods to account for changes in fuel moisture, one of the main drivers of variability in fire emissions. From our review and synthesis, we identify key uncertainties and areas of improvement for understanding the magnitude and spatial-temporal patterns of pyrogenic carbon emissions across North America.

AB Fusarium oxysporum is a fungal pathogen that attacks many important plants. Uniquely pathogenic strains of F. oxysporum f. sp. vasinfectum were inadvertently imported into the United States on live cottonseed for dairy cattle feed. These strains produce exceptionally high concentrations of the phytotoxin fusaric acid. Thus, fusaric acid may be a critical component in the pathogenicity of these biotypes. This study investigated the biosynthesis of fusaric acid using (13)C-labeled substrates including [1,2- (13)C(2)] acetate as well as (13)C- and (15)N-labeled aspartate and [(15)N]glutamine. The incorporation of labeled substrates is consistent with the biosynthesis of fusaric acid from three acetate units at C5-C6, C7-C8, and C9-C10, with the remaining carbons being derived from aspartate via oxaloacetate and the TCA cycle; the oxaloacetate originates in part by transamination of aspartate, but most of the oxaloacetate is derived by deamination of aspartate to fumarate by aspartase. The nitrogen from glutamine is more readily incorporated into fusaric acid than that from aspartate.

AB Polybrominated diphenyl ether (PBDE) body burdens in the general U.S. population have been linked to the consumption of red meat and poultry. Exposure estimates have also indicated that meat products are a major contributor to PBDE dietary intake. To establish solid estimates of PBDE concentrations in domestic meat and poultry, samples from two statistically designed surveys of U.S. meat and poultry were analyzed for PBDEs. The two surveys were conducted in 2002-2003 and 2007-2008; between which times the manufacturing of penta-BDE and octa-BDE formulations had ceased in the United States (December :2004). Thus, the data provided an opportunity to observe prevalence and concentration trends that may have occurred during this time frame and to compare the mean PBDE levels among the meat and poultry industries. On the basis of composite samples, the average sum of the seven most prevalent PBDEs (BDE-28, -47, -99, -100, -153, -154, and -183) decreased by > 60% from 1.95 ng/g lipid in 2002-2003 to 0.72 ng/g lipid in 2007-2008 for meat and poultry. PBDEs measured in individual samples in 2008 showed that beef samples had the lowest PBDE levels followed by hogs and chickens and then by turkeys. The PBDE congener pattern was the same for both surveys and resembled the penta-BDE formulation with BDE-47 and -99 accounting for 30 and 40% of the total, respectively. On the basis of the data from the two surveys, it appears that PBDE levels in U.S. meat and poultry have declined since manufacturing ceased; however, exposure pathways of PBDEs to livestock are still not known.

AB Analysis of gene polymorphisms and disease association is essential for assessing putative candidate genes affecting susceptibility or resistance to disease. In this paper, we report the results of an association analysis between single nucleotide polymorphisms (SNPs) in common carp (Cyprinus carpio) innate immune response genes and resistance to cyprinid herpesvirus-3 (CyHV-3) infection. Twenty-three SNPs from 14 genes were genotyped in the progeny of a full-sib family, which was subjected to a CyHV-3 challenge. The challenge was carried out by cohabitation of naive fish with CyHV-3-infected fish and the experimental fish subsequently were scored as susceptible or resistant. Fisher exact probability and chi-square tests were used to assess the association of SNP genotypes or alleles with CyHV-3 resistance. No association between SNPs in common carp immune response genes and resistance to CyHV-3 was found, except for SNPs in IL-10a. For IL-10a, both heterozygous and homozygous fish carrying the GCG haplotype were more susceptible to CyHV-3 infection (P<0.001). To identify the source of susceptible and resistant alleles, we genotyped fish from the parental common carp strains. We found that the susceptible allele was more common among fish from the wild CyHV-3-resistant strain (Sassan) whereas the resistant allele was found in all the fish sampled from the susceptible domesticated strain (Nasice). The implications of our findings to the development of a domesticated CyHV-3-resistant stock through marker-assisted selection or gene-introgression, and the possible impact of the IL-10a polymorphisms we identified on susceptibility to CyHV-3 infection in common carp are discussed.

AB [1] We developed a water-centric monthly scale simulation model (WaSSI-C) by integrating empirical water and carbon flux measurements from the FLUXNET network and an existing water supply and demand accounting model (WaSSI). The WaSSI-C model was evaluated with basin-scale evapotranspiration (ET), gross ecosystem productivity (GEP), and net ecosystem exchange (NEE) estimates by multiple independent methods across 2103 eight-digit Hydrologic Unit Code watersheds in the conterminous United States from 2001 to 2006. Our results indicate that WaSSI-C captured the spatial and temporal variability and the effects of large droughts on key ecosystem fluxes. Our modeled mean (+/- standard deviation in space) ET (556 +/- 228 mm yr(-1)) compared well to Moderate Resolution Imaging Spectroradiometer (MODIS) based (527 +/- 251 mm yr(-1)) and watershed water balance based ET (571 +/- 242 mm yr(-1)). Our mean annual GEP estimates (1362 +/- 688 g C m(-2) yr(-1)) compared well (R-2 = 0.83) to estimates (1194 +/- 649 g C m(-2) yr(-1)) by eddy flux-based EC-MOD model, but both methods led significantly higher (25-30%) values than the standard MODIS product (904 +/- 467 g C m(-2) yr(-1)). Among the 18 water resource regions, the southeast ranked the highest in terms of its water yield and carbon sequestration capacity. When all ecosystems were considered, the mean NEE (-353 +/- 298 g C m(-2) yr(-1)) predicted by this study was 60% higher than EC-MOD's estimate (-220 +/- 225 g C m(-2) yr(-1)) in absolute magnitude, suggesting overall high uncertainty in quantifying NEE at a large scale. Our water-centric model offers a new tool for examining the trade-offs between regional water and carbon resources under a changing environment.

AB During construction of the whole body counter (WBC) at the Children's Nutrition Research Center (CNRC), efficiency calibration was needed to translate acquired counts of (40)K to actual grams of potassium for measurement of total body potassium (TBK) in a diverse subject population. The MCNP Monte Carlo n-particle simulation program was used to describe the WBC (54 detectors plus shielding), test individual detector counting response, and create a series of virtual anthropomorphic phantoms based on national reference anthropometric data. Each phantom included an outer layer of adipose tissue and an inner core of lean tissue. Phantoms were designed for both genders representing ages 3.5 to 18.5 years with body sizes from the 5th to the 95th percentile based on body weight. In addition, a spherical surface source surrounding the WBC was modeled in order to measure the effects of subject mass on room background interference. Individual detector measurements showed good agreement with the MCNP model. The background source model came close to agreement with empirical measurements, but showed a trend deviating from unity with increasing subject size. Results from the MCNP simulation of the CNRC WBC agreed well with empirical measurements using BOMAB phantoms. Individual detector efficiency corrections were used to improve the accuracy of the model. Nonlinear multiple regression efficiency calibration equations were derived for each gender. Room background correction is critical in improving the accuracy of the WBC calibration.

AB An integrated approach based on high resolution MS analysis (orbitrap), database (db) searching and MS/MS fragmentation prediction for the rapid identification of plant phenols is reported. The approach was firstly validated by using a mixture of phenolic standards (phenolic acids, flavones, flavonols. flavanones, flavanols, isoflavones). In particular, the integrated approach consists of the following steps: (1) LC-ESI-MS/MS analysis in data dependent scan mode using an orbitrap mass analyzer (resolution 60,000; positive ion-mode, ESI source); (2) searching the experimental monoisotopic masses (tolerance 1 ppm) in plant phenols databases; (3) filtering the entries on the basis of the phenol class to which the unknown belongs, as determined on the basis of the UV spectrum. Final identification is achieved by matching the isotopic pattern and by MS/MS fragmentation studies. In particular, experimental MS/MS fragments are matched with those predicted by a commercially available software. The method was then successfully applied for the rapid identification of phenolics contained in an EtOH extract of Angelica keiskei. (C) 2011 Elsevier ay. All rights reserved.

AB PhzE utilizes chorismate and glutamine to synthesize 2-amino-2-desoxyisochorismate (ADIC) in the first step of phenazine biosynthesis. The PhzE monomer contains both a chorismate-converting menaquinone, siderophore, tryptophan biosynthesis (MST) and a type 1 glutamine amidotransferase (GATase1) domain connected by a 45-residue linker. We present here the crystal structure of PhzE from Burkholderia lata 383 in a ligand-free open and ligand-bound closed conformation at 2.9 and 2.1 angstrom resolution, respectively. PhzE arranges in an intertwined dimer such that the GATase1 domain of one chain provides NH3 to the MST domain of the other. This quaternary structure was confirmed by small angle x-ray scattering. Binding of chorismic acid, which was found converted to benzoate and pyruvate in the MST active centers of the closed form, leads to structural rear-rangements that establish an ammonia transport channel approximately 25 angstrom in length within each of the two MST/GATase1 functional units of the dimer. The assignment of PhzE as an ADIC synthase was confirmed by mass spectrometric analysis of the product, which was also visualized at 1.9 angstrom resolution by trapping in crystals of an inactive mutant of PhzD, an isochorismatase that catalyzes the subsequent step in phenazine biosynthesis. Unlike in some of the related anthranilate synthases, no allosteric inhibition was observed in PhzE. This can be attributed to a tryptophan residue of the protein blocking the potential regulatory site. Additional electron density in the GATase1 active center was identified as zinc, and it was demonstrated that Zn2+, Mn2+, and Ni2+ reduce the activity of PhzE.

AB The Chinese rose beetle, Adoretus sinicus Burmeister (Coleoptera: Scarabaeidae: Rutelinae: Adoretini), is a broadly polyphagous scarab beetle that is economically important and causes damage to a wide variety of host plants including agricultural crops and ornamentals in Southeast Asia, China, the Hawaiian Islands and several other Pacific Islands. The species has become established in numerous regions and is of biosecurity concern because importation of this species to other regions poses a threat to agriculture due to its generalist herbivore feeding habits. Field and laboratory research directed towards control of the species is hampered by the lack of characteristics that allow accurate determination of the sexes on live beetles in the field. Here, three recognizable and reliable non-destructive morphological differences between the sexes of A. sinicus are documented: (1) the form of the terminal sternite; (2) the length to width ratio of protarsomere 1, and; 3) the ratio of the combined length of protarsomeres 2-4 to the length of protarsomere 1. Because many Adoretus species are of biosecurity concern, and because tools to identify Adoretus species are lacking, we review the natural history and research on control associated with A. sinicus as well as the genus as a whole.

AB Background: Melon (Cucumis melo), an economically important vegetable crop, belongs to the Cucurbitaceae family which includes several other important crops such as watermelon, cucumber, and pumpkin. It has served as a model system for sex determination and vascular biology studies. However, genomic resources currently available for melon are limited.
Result: We constructed eleven full-length enriched and four standard cDNA libraries from fruits, flowers, leaves, roots, cotyledons, and calluses of four different melon genotypes, and generated 71,577 and 22,179 ESTs from full-length enriched and standard cDNA libraries, respectively. These ESTs, together with similar to 35,000 ESTs available in public domains, were assembled into 24,444 unigenes, which were extensively annotated by comparing their sequences to different protein and functional domain databases, assigning them Gene Ontology (GO) terms, and mapping them onto metabolic pathways. Comparative analysis of melon unigenes and other plant genomes revealed that 75% to 85% of melon unigenes had homologs in other dicot plants, while approximately 70% had homologs in monocot plants. The analysis also identified 6,972 gene families that were conserved across dicot and monocot plants, and 181, 1,192, and 220 gene families specific to fleshy fruit-bearing plants, the Cucurbitaceae family, and melon, respectively. Digital expression analysis identified a total of 175 tissue-specific genes, which provides a valuable gene sequence resource for future genomics and functional studies. Furthermore, we identified 4,068 simple sequence repeats (SSRs) and 3,073 single nucleotide polymorphisms (SNPs) in the melon EST collection. Finally, we obtained a total of 1,382 melon full-length transcripts through the analysis of full-length enriched cDNA clones that were sequenced from both ends. Analysis of these full-length transcripts indicated that sizes of melon 5' and 3' UTRs were similar to those of tomato, but longer than many other dicot plants. Codon usages of melon full-length transcripts were largely similar to those of Arabidopsis coding sequences.
Conclusion: The collection of melon ESTs generated from full-length enriched and standard cDNA libraries is expected to play significant roles in annotating the melon genome. The ESTs and associated analysis results will be useful resources for gene discovery, functional analysis, marker-assisted breeding of melon and closely related species, comparative genomic studies and for gaining insights into gene expression patterns.

AB Currently, a large number of microsatellites are available for Rotylenchulus reniformis (reniform nematode); however, two barriers exist for genotyping samples from different geographical areas. The limited amount of nucleic acids obtained from single nematodes which would require their multiplication to obtain enough DNA for testing; and the strictly regulated transport of live samples and multiplication in greenhouse for being a plant pathogen. Whole-genome amplification (WGA) of samples consisting of one and five dead gravid females with their associated egg masses was successfully performed on disrupted tissue using three commercial kits. DNA yield after WGA ranged from 0.5 to 8 mu g and was used to test 96 microsatellite markers we previously developed for the reniform nematode. The results were compared to those of fingerprinting the original population (MSRR03). Out of 96 markers tested, 71 had amplicons in MSRR03. Using WGA of single gravid females with their associated egg masses, 86-93% of the alleles found on MSRR03 were detected, and 87-88% of the alleles found on MSRR03 when using WGA of samples composed of five gravid females with their associated egg masses as template. Our results indicate that reniform nematode samples as small as a single gravid female with her associated egg mass can be used in WGA and direct testing with microsatellites, giving consistent results when compared to the original population.

AB Climate change is expected to increase the intensity of precipitation, but our ability to model the consequences for soil respiration are limited by a lack of data from soils that are saturated and draining. In this study, we used large intact soil columns (28 x 30 cm) to 1) quantify changes in CO(2) flux as soils drain from saturated conditions, and 2) to determine which soil water metrics best predict instantaneous maximum CO(2) flux. The columns were from three agricultural landscape positions that vary in soil properties. We simulated water table fluctuations that were observed at the field site (and predicted to increase in future climate scenarios) by flooding the columns from bottom to surface and then allowing the columns to drain for 96 h while monitoring volumetric soil water content (VWC), water filled pore space (WFPS), water content normalized to field capacity, matric potential, and CO(2) flux. Mean cumulative CO(2) flux was 4649 mg CO(2)-Cm(-2) 96 h(-1). Regardless of landscape position. CO(2) flux rates exhibited a single maximum slightly below saturation, near field capacity. This result suggests that many field studies have not captured soil respiration rates when water availability is optimum for heterotrophic respiration. Across landscape positions, matric potential was the most consistent indicator of instantaneous maximum CO(2) flux, with maximum fluxes occurring within the narrow range of -0.15 to -4.89 kPa. In contrast, instantaneous maximum CO(2) flux rates occurred between 95 and 131% of water content normalized to field capacity, 72-97% WFPS, and 29-45% VWC. Thus, our data suggest that instantaneous maximum CO(2) flux rates, a key parameter in ecosystem models, can be predicted across an agricultural landscape with diverse soils if matric potential is used as a water scalar.

AB This study determined Cd speciation and release kinetics in a Cd-Zn cocontaminated alkaline paddy soil, under various flooding periods and draining conditions, by employing synchrotron-based techniques, and a stirred-flow kinetic method. Results revealed that varying flooding periods and draining conditions affected Cd speciation and its release kinetics. Linear least-squares fitting (LLSF) of bulk X-ray absorption fine structure (XAFS) spectra of the air-dried, and the 1 day-flooded soil samples, showed that at least 50% of Cd was bound to humic acid. Cadmium carbonates were found as the major species at most flooding periods, while a small amount of cadmium sulfide was found the soils were flooded for longer periods. Under all flooding and draining conditions, at least 14 mg/kg Cd was desorbed from the soil after a 2-hour desorption experiment. The results obtained by micro X-ray fluorescence (mu-XRF) spectroscopy showed that Cd was less associated with Zn than Ca, in most soil samples. Therefore, it is more likely that Cd and Ca will be present in the same mineral phases rather than Cd and Zn, although the source of these two latter elements may originate from the same surrounding Zn mines in the Mae Sot district.

AB The enteral metabolisms of glutamine and citrulline are intertwined because, while glutamine is one of the main fuel sources for the enterocyte, citrulline is one of its products. It has been shown that the administration of N-15-labeled glutamine results in the incorporation of the N-15 label into citrulline, but it is not clear which of the three nitrogen groups of citrulline is actually labeled. To determine the N-15-enrichment of the positional isomers of glutamine and citrulline, a rapid liquid chromatography/tandem mass spectrometry (LC/MS/MS) method was developed. The amino acids were analyzed as their dansyl derivatives. The product ion resulting from the loss of NH3 from the omega carbon allows for the determination of the enrichment of the ureido (citrulline) or amido groups (glutamine). The protonated pyrrolidine (citrulline) or 5-oxopyrrolidine (glutamine) product ion contains the 2-N (amino group) and is used to determine its enrichment. The method described showed no ion suppression and a wide dynamic range ranging from 1.3 picomoles to 2 nanomoles for citrulline. Background samples and standards resulted in enrichments not different from those theoretically expected. The enrichment curves for the different glutamine and citrulline isotopomers were linear (R-2 > 0.998) over the range of enrichments studied. The method developed provides an additional insight into the metabolism of glutamine and citrulline tracing the precursor-product relationship between these two amino acids.

AB Objectives of the present study were to characterize the dose dependency of an intravenous Escherichia coli O111:H8 challenge in colostrum-fed Jersey calves and to identify any biochemical markers indicative of septicemia. Eighteen 3-week old colostrum-fed Jersey calves were completely randomized to 1 of 6 doses of E. coli O111:H8. The challenge doses included 0, 1.5 x 10(5), 1.5 x 10(6), 1.5 x 10(7), 1.5 x 10(8), and 1.5 x 1(0)9 colony-forming units (CFU) given intravenously as a bolus in 5 mL of sterile isotonic saline. Peripheral blood samples were collected at 0, 2, 4, 8, 12, 24, and 48 h relative to the challenge for biochemical, total leukocyte count, and differential analyses. Rectal temperatures were collected via indwelling rectal temperature probes at 5-min intervals, and hourly averages calculated from 2 d prior to the challenge till 2 d after the challenge. All calves survived the 48 h observation period following the challenge. Calves given 1.5 x 10(8) and 1.5 x 10(9) CPU displayed sickness behaviors (P < 0.01) beginning 0.5 h after the challenge and returned to that of the control calves by 6 and 32 h for calves challenged with 1.5 x 10(8) and 1.5 x 10(9) CPU, respectively. There were treatment x time interactions (P < 0.01) on total leukocyte counts and plasma glucose and zinc concentrations. Calves administered 1.5 x 10(8) and 1.5 x 10(9) CPU had leucopenia beginning 2 h after the challenge and returning to counts similar to the control calves within 24 h. Additionally, those calves were hypoglycemic from 4 to 12 h after the challenge with the degree of hypoglycemia inversely related to the dose of the E. coli. All calves challenged with E. coli had decreased plasma zinc concentrations, and the magnitude was inversely proportional to the challenge dose. There were treatment x time interactions (P < 0.001) on rectal temperatures following the challenge. All calves challenged with E. coli developed a febrile response, but the intensity and duration of the response were dependent on the challenge dose. These data indicate that calves intravenously challenged with 1.5 x 10(8) and 1.5 x 10(9) CPU of the E. coli O111:H8 showed immediate clinical and biochemical signs indicative of septicemia. However, calves administered 1.5 x 10(7) or less of the E. coli had febrile responses, but did not develop septicemia. Blood glucose and zinc concentrations may be dose responsive indicators that could potentially differentiate between a se pticemic versus non-septicemic calf. (C) 2011 Elsevier B.V.

AB Leukotoxin (Lkt) and LPS are the major virulence determinants of Mannheimia haemolytica that contribute to the pathogenesis of bovine and ovine pneumonic pasteurellosis. We have previously identified bovine and ovine CD18 as the functional receptor for Lkt. LPS complexes with Lkt resulting in increased thermal stability and enhanced cytotoxic activity of Lkt. Cellular recognition of LPS involves several different molecules including CD14. We hypothesized that expression of ovine CD14 together with LFA-1 or Mac-1 would enhance Lkt-induced cytotoxicity. Ovine cDNA for CD14 was amplified by PCR and cloned into mammalian expression vectors. The 1122 bp cDNAs for bighorn sheep (BHS) and domestic sheep (DS) CD14 encode 373 amino acids which exhibit 99% identity with each other. Ovine CD14 plasmids were transfected either into HEK-293 cells, or previous HEK-293 transfectants stably expressing ovine LFA-1 or Mac-1. Flow cytometric analysis of transfectants confirmed the cell surface expression of CD14. The transfectants expressing LFA-1 or Mac-1 and the transfectants co-expressing CD14 with LFA-1 or Mac-1 did not show any significant difference in Lkt-induced cytotoxicity when incubated with LPS complexed Lkt. In contrast, incubation of the LFA-1 or Mac-1 and LFA-1/CD14 or Mac-1/CD14 transfectants with Lkt which lacks LPS, resulted in reduced cytotoxicity. None of the above transfectants showed any difference in [Ca(2+)](i) elevation when incubated with both types of Lkt preparations. Lkt did not induce any cytotoxicity or [Ca(2+)](i) elevation in ovine CD14 transfectants or parent HEK-293 cells. Based on these findings, we conclude that expression of CD14 together with LFA-1 or Mac-1 does not enhance Lkt-induced cytotoxicity, whereas LPS enhances cytotoxicity by complexing with Lkt.

ID PLASTIC COMPOSITES; FIBER
AB Though silane chemistry has been used to crosslink unfilled polyethylene for many years, such crosslinking has only been recently applied to wood plastic composites to improve properties such as creep resistance. However, the presence of wood significantly changes the silane chemistry and a greater understanding is necessary for optimal processing and performance. We investigated three different approaches of adding silane and peroxide during reactive extrusion of wood-plastic composites were investigated and compared to their unfilled counterparts. Up to 2 grams of a 20:1 solution of vinyltrimethoxysilane and dicumyl peroxide by weight were added per 100 grams of plastic. Low density polyethylene, high density polyethylene, and a blend of the two were investigated as matrices in composites containing approximately 25% wood flour. The unfilled plastics crosslinked efficiently and little premature crosslinking occurred during processing. Though only modest improvements in tensile strengths were found in unfilled plastics, the notched Izod impact energy of unfilled HDPE improved nearly 600% when crosslinked. Unlike the unfilled plastics, most of the crosslinking of the composites occurred during processing. This resulted in high viscosities and processing difficulties, negating some of the advantages of a separate crosslinking step and limiting the amount of crosslinking possible. Some reinforcement of the plastics by the wood flour was achieved when sufficient crosslinking solution was added. Adding crosslinking solution also and greatly increased reverse-notched impact energies. The differences between the approaches for preparing the crosslinked composites appeared to largely be a matter of efficiency in terms of the amount of crosslinking solution required to affect processing and performance. The most efficient approach was a two-step procedure where the silane was first grafted to the plastic and then wood flour was compounded with the grafted silane in a second step.

AB Production of type A trichothecenes has been reported in the closely related species Fusarium langsethiae and F. sporotrichioides. Here, we characterized a collection of Fusarium isolates from Siberia and the Russian Far East (hereafter Asian isolates) that produce high levels of the type A trichothecene T-2 toxin and are similar in morphology to the type A trichothecene-producing F. langsethiae, and to F. poae which often produces the type B trichothecene nivalenol. The Asian isolates possess unique macroscopic and microscopic characters and have a unique TG repeat in the nuclear ribosomal intergenic spacer (IGS rDNA) region. In Asian isolates, the TRI1-TRI16 locus, which determines type A versus type B trichothecene production in other species, is more similar in organization and sequence to the TRI1-TRI16 locus in F. sporotrichioides and F. langsethiae than to that in F. poae. Phylogenetic analysis of the TRI1 and TRI16 gene coding regions indicates that the genes in the Asian isolates are more closely related to those of F. sporotrichioides than F. langsethiae. Phylogenetic analysis of the beta-tubulin, translation elongation factor. RNA polymerase II and phosphate permease gene sequences resolved the Asian isolates into a well-supported sister lineage to F. sporotrichioides, with F. langsethiae forming a sister lineage to F. sporotrichioides and the Asian isolates. The Asian isolates are conspecific with Norwegian isolate IBT 9959 based on morphological and molecular analyses. In addition, the European F. langsethiae isolates from Finland and Russia were resolved into two distinct subgroups based on analyses of translation elongation factor and IGS rDNA sequences. Nucleotide polymorphisms within the IGS rDNA were used to design PCR primers that successfully differentiated the Asian isolates from F. sporotrichioides and F. langsethiae. Based on these data, we formally propose that the Asian isolates together with Norwegian isolate IBT 9959 comprise a novel phylogenetic species. F. sibiricum, while the two subgroups of F. langsethiae only represent intraspecific groups. (C) 2011 Elsevier B.V. All rights reserved.

AB Comparing photosynthetic and photovoltaic efficiencies is not a simple issue. Although both processes harvest the energy in sunlight, they operate in distinctly different ways and produce different types of products: biomass or chemical fuels in the case of natural photosynthesis and nonstored electrical current in the case of photovoltaics. In order to find common ground for evaluating energy-conversion efficiency, we compare natural photosynthesis with present technologies for photovoltaic-driven electrolysis of water to produce hydrogen. Photovoltaic-driven electrolysis is the more efficient process when measured on an annual basis, yet short-term yields for photosynthetic conversion under optimal conditions come within a factor of 2 or 3 of the photovoltaic benchmark. We consider opportunities in which the frontiers of synthetic biology might be used to enhance natural photosynthesis for improved solar energy conversion efficiency.

AB Background: Allergic reactions to peanuts (Arachis hypogaea L.) can cause severe symptoms and in some cases can be fatal, but avoidance is difficult due to the prevalence of peanut-derived products in processed foods. One strategy of reducing the allergenicity of peanuts is to alter or eliminate the allergenic proteins through mutagenesis. Other seed quality traits could be improved by altering biosynthetic enzyme activities. Targeting Induced Local Lesions in Genomes (TILLING), a reverse-genetics approach, was used to identify mutations affecting seed traits in peanut.
Results: Two similar copies of a major allergen gene, Ara h 1, have been identified in tetraploid peanut, one in each subgenome. The same situation has been shown for major allergen Ara h 2. Due to the challenge of discriminating between homeologous genes in allotetraploid peanut, nested PCR was employed, in which both gene copies were amplified using unlabeled primers. This was followed by a second PCR using gene-specific labeled primers, heteroduplex formation, CEL1 nuclease digestion, and electrophoretic detection of labeled fragments. Using ethyl methanesulfonate (EMS) as a mutagen, a mutation frequency of 1 SNP/967 kb (3,420 M(2) individuals screened) was observed. The most significant mutations identified were a disrupted start codon in Ara h 2.02 and a premature stop codon in Ara h 1.02. Homozygous individuals were recovered in succeeding generations for each of these mutations, and elimination of Ara h 2.02 protein was confirmed. Several Ara h 1 protein isoforms were eliminated or reduced according to 2D gel analyses. TILLING also was used to identify mutations in fatty acid desaturase AhFAD2 (also present in two copies), a gene which controls the ratio of oleic to linoleic acid in the seed. A frameshift mutation was identified, resulting in truncation and inactivation of AhFAD2B protein. A mutation in AhFAD2A was predicted to restore function to the normally inactive enzyme.
Conclusions: This work represents the first steps toward the goal of creating a peanut cultivar with reduced allergenicity. TILLING in peanut can be extended to virtually any gene, and could be used to modify other traits such as nutritional properties of the seed, as shown in this study.

AB Current methods for sustainable control of avian coccidiosis, whether by prophylactic medication or parasite vaccination, are suboptimal. In this study, we describe an alternative immunization strategy against Eimeria tenella infection using parasite antigen (Ag)-loaded dendritic cells (DCs), or their derived exosomes, in the absence of free Ag. CD45(+) intestinal DCs were isolated from E. tenella-infected chickens and loaded ex vivo with an extract of sporozoites as parasite Ag. Extracellular vesicles purified from the Ag-pulsed DCs expressed surface proteins associated with DC-derived exosomes, including major histocompatibility complex proteins (MHC I and MHC II), CD80, flotillin, and heat shock protein (HSP70). Following intramuscular immunization of chickens with Ag-pulsed DCs or Ag-pulsed DC-derived exosomes, Ag-containing cells were observed diffusely localized in the lymphoid tissue and concentrated in germinal centers of caecal tonsils, and restricted to germinal centers (GC) in the spleen. Chickens immunized with pulsed DCs or exosomes exhibited (a) higher numbers of caecal tonsil and spleen cells expressing IgG and/or IgA antibodies that were reactive with E. tenella Ag, (b) greater numbers of IL-2-, IL-16-, and IFN-gamma-producing cells, and (c) higher E. tenella Ag-driven cell proliferation, compared with chickens immunized with Ag in the absence of DCs or exosomes. Chickens immunized with Ag-pulsed DCs or Ag-pulsed DC-derived exosomes and subsequently given a live E. tenella challenge infection at 10 d post-immunization displayed (a) increased body weight gains, (b) decreased feed conversion ratios, (c) reduced fecal oocyst shedding, (d) diminished intestinal lesions, and (e) lower mortality, compared with animals given Ag alone. This is the first demonstration of Ag-specific protective immunity against avian coccidiosis using parasite Ag-loaded DCs or DC-derived exosomes. (C) 2011 Elsevier Ltd. All rights reserved.

AB The mucus layer in the gastrointestinal (GI) tract is considered to be the first line of defense to the external environment. Alteration in mucus components has been reported to occur during intestinal nematode infection in ruminants, but the role of mucus in response to abomasal parasites remains largely unclear. The aim of the current study was to analyze the effects of an Ostertagia ostertagi infection on the abomasal mucus biosynthesis in cattle. Increased gene expression of MUC1, MUC6 and MUC20 was observed, while MUC5AC did not change during infection. Qualitative changes of mucins, related to sugar composition, were also observed. AB-PAS and HID-AB stainings highlighted a decrease in neutral and an increase in acidic mucins, throughout the infection. Several genes involved in mucin core structure synthesis, branching and oligomerization, such as GCNT3, GCNT4, A4GNT and protein disulphide isomerases were found to be upregulated. Increase in mucin fucosylation was observed using the lectin UEA-I and through the evaluation of fucosyltransferases gene expression levels. Finally, transcription levels of 2 trefoil factors, TFF1 and TFF3, which are co-expressed with mucins in the GI tract, were also found to be significantly upregulated in infected animals. Although the alterations in mucus biosynthesis started early during infection, the biggest effects were found when adult worms were present on the surface of the abomasal mucosa and are likely caused by the alterations in mucosal cell populations, characterized by hyperplasia of mucus secreting cells.

AB Muskmelons, both cantaloupe (Cucumis melo Reticulatus Group) and orange-fleshed honeydew (C. melo Inodorus Group), a cross between orange-fleshed cantaloupe and green-fleshed honeydew, are excellent sources of beta-carotene. Although beta-carotene from melon is an important dietary antioxidant and precursor of vitamin A, its bioaccessibility/bioavailability is unknown. We compared beta-carotene concentrations from previously frozen orange-fleshed honeydew and cantaloupe melons grown under the same glasshouse conditions, and from freshly harvested field-grown, orange-fleshed honeydew melon to determine beta-carotene bioaccessibility/bioavailability, concentrations of novel beta-apocarotenals, and chromoplast structure of orange-fleshed honeydew melon. beta-Carotene and beta-apocarotenal concentrations were determined by HPLC and/or HPLC-MS, beta-carotene bioaccessibility/bioavailability was determined by in vitro digestion and Caco-2 cell uptake, and chromoplast structure was determined by electron microscopy. The average beta-carotene concentrations (mu g/g dry weight) for the orange-fleshed honeydew and cantaloupe were 242.8 and 176.3 respectively. The average dry weights per gram of wet weight of orange-fleshed honeydew and cantaloupe were 0.094 g and 0.071 g, respectively. The bioaccessibility of field-grown orange-fleshed honeydew melons was determined to be 3.2 +/- 0.3%, bioavailability in Caco-2 cells was about 11%, and chromoplast structure from orange-fleshed honeydew melons was globular (as opposed to crystalline) in nature. We detected beta-apo-8'-, beta-apo-10', beta-apo-12'-, and beta-apo-14'-carotenals and beta-carotene than cantaloupe. The bioaccessibility/bioavailability of beta-carotene from orange-fleshed melons was comparable to that from carrot (Daucus carota).

AB Engeletin, a flavonoid compound, was isolated from the leaves of Engelhardia roxburghiana for the first time, along with astilbin, another flavonoid. The chemical structures of engeletin and astilbin were confirmed by (1)H and (13)C nuclear magnetic resonance (NMR) and mass spectrometry (MS) spectra, and their anti-inflammatory activities were studied in lipopolysaccharide (LPS)-stimulated mouse J774A.1 macrophage cells. LPS induced the inflammatory state in macrophage cells and increased mRNA expressions of pro-inflammatory cytokines. Engeletin and astilbin exhibited remarkable inhibitory effects on interleukin (IL)-1 beta and IL-6 mRNA expression. Significant inhibition of LPS-mediated mRNA expressions were also seen in LPS binding toll-like receptor (TLR)-4, pro-inflammatory cytokine tumor necrosis factor (TNF)-alpha, IL-10, chemoattractant monocyte chemotactic protein (MCP)-1, and cyclooxygenase (COX)-2 genes. The reduced expression of these cytokines may alleviate immune response and reduce inflammatory activation, indicating that engeletin and astilbin may serve as potential anti-inflammatory agents.

AB A new liquid rice hull smoke extract with a smoky aroma and sugar-like odor prepared by pyrolysis of rice hulls followed by liquefaction of the resulting smoke contained 161 compounds characterized by GC/MS. Antioxidative, antiallergic, and anti-inflammatory activities of the extract were assessed in vitro and in vivo. At pH 5, the extract inhibited 1-dipheny1-2-picrylhydrazyl (DPPH) free radicals and suppressed nitric oxide (NO) and beta-hexosaminidase releases from lipopolysaccharide (LPS)-induced RAW264.7 mouse macrophage leukemia cells and ionophore A23187-stimulated RBL-2H3 rat basophilic cells without significant cytotoxicity. 12-O-Tetradecanolylphorbol-13-acetate (TPA) was applied to the ears of CD-1 mice to induce inflammation (edema), which was accompanied by increases in a series of biomarkers. Topical application of 1% of the extract as well as feeding mice a standard diet with 1% extract for two weeks significantly reduced the expression of biomarkers associated with the TPA-induced inflammation. These include tumor necrosis factor-alpha (TNF-alpha), IL-1 beta, interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), leukotriene B-4 (LTB4), prostaglandin E-2 (PGE(2)), myeloperoxidase (MPO). These in vitro and in vivo findings demonstrate the potential value of rice hull smoke extract derived from a major agricultural byproduct to serve as a new biomaterial for the improvement of food quality and safety and the environment.

AB Although extrusion technology has contributed much to increasing the effective utilization of whey, the effect of extrusion conditions on the functional properties of the proteins is not well understood. In this work, the impact of extrusion temperature on the physical and chemical properties, molecular structures, and protein quality of texturized whey protein isolate (WPI) was investigated at a constant moisture content and compared with WPI treated with simple heat only. The Bradford assay methods, sodium dodecyl sulfate polyacrylamide gel electrophoresis, and reversed-phase high-performance liquid chromatography techniques were used to determine protein solubility and to analyze compositional changes in the two major whey proteins, alpha-lactalbumin and beta-lactoglobulin. Circular dichroism and intrinsic tryptophan fluorescence spectroscopic techniques were applied to study the secondary and tertiary structures of the proteins. This study demonstrated that extrusion temperature is a critical but not the sole determining factor in affecting the functional properties of extruded WPI.

AB Most industrial lubricants are derived from nonrenewable petroleum-based sources. As useful as these lubricants are, their unintended consequences are the pollution of the Earth's environment as a result of the slow degradation of the spent materials. Native seed oils, on the other hand, are renewable and are also biodegradable in the environment, but these oils often suffer a drawback in having lower thermal stability and a shorter shelf life because of the intrinsic -C=C- unsaturation in their structures. This drawback can be overcome, yet the inherent biodegradative property retained, by appropriate derivatization of the oil. Pursuant to this, this study investigated derivatized polyhydroxy milkweed oil to assess its suitability as lubricant. The milkweed plant is a member of the Asclepiadaceae, a family with many genera including the common milkweeds, Asclepias syriaca L., Asclepias speciosa L., Asclepias tuberosa L., etc. The seeds of these species contain mainly C-18 triglycerides that are highly unsaturated, 92%. The olefinic character of this oil has been chemically modified by generating polyhydroxy triglycerides (HMWO) that show high viscosity and excellent moisturizing characteristics. In this work, HMWO have been chemically modified by esterifying their hydroxyl groups with acyl groups of various chain lengths (C2-C5). The results of investigation into the effect of the acyl derivatives' chemical structure on kinematic and dynamic viscosity, oxidation stability, cold-flow (pour point, cloud point) properties, coefficient of friction, wear, and elastohydrodynamic film thickness are discussed.

AB Dietary phytic acid is a major causative factor for low Zn bioavailability in many cereal- and legume-based diets. The bioavailability of Zn in seed of low phytic acid (lpa) variants of maize (Zea mays L.), rice (Oryza sativa L.), and barley (Hordeum vulgare L.) was evaluated using a suckling rat pup model. Suckling rat pups (14 days old, n = 6-8/treatment) were fasted for 6 h and intubated with Zn-65-radiolabeled suspensions prepared using seed produced by either wild-type (normal phytic acid) or lpa genotypes of each cereal. Test solutions were radiolabeled overnight (all genotypes) or immediately prior to intubation (barley genotypes). Pups were killed 6 h postintubation and tissues removed and counted in a gamma counter. Zn absorption was low from wild-type genotypes of maize (21, 33%) and rice (26%), and phytic acid reduction resulted in significantly higher Zn absorption, 47-52 and 35-52%, respectively. Zn absorption from wild-type barley incubated overnight was high (86-91%), and phytate reduction did not improve Zn absorption (84-90%), which is likely due to endogenous phytase activity. When the wild-type barley solutions were prepared immediately before intubation, Zn absorption was significantly lower (63, 78%) than from the lpa cultivars (92, 96%). Variation in seed or flour phenolic acid levels did not affect Zn absorption. Differences in seed Zn levels did not substantially affect Zn absorption. Thus, when phytic acid is abundant in a diet, it has a larger effect on Zn absorption than the level of Zn. Therefore, reducing the phytic acid content of staple cereal grains may contribute to enhancing Zn nutrition of populations consuming these staple foods.

AB High temperature during grain fill reduces wheat yield and alters flour quality. Starchy endosperm cell morphology was investigated in wheat (Triticum aestivum L. 'Butte 86') grain produced under a 24/17 or 37/28 degrees C day/night regimen imposed from anthesis to maturity to identify changes in cell structure related to the functional properties of flour. The duration of grain fill decreased substantially under the 37/28 degrees C regimen, but, like the 24/17 degrees C regimen, endosperm cells in the mature grain were packed with starch and protein. However, A-type starch granules increased in number, decreased in size, and exhibited pitting; B-type granules decreased in both number and size; and the protein matrix was proportionally greater in endosperm cells of grain produced under the 37/28 degrees C regimen. Such changes in starch granule number, size, and structure and in protein amount are known to contribute to variations in wheat flour quality.

AB Background: Root-knot nematodes are sedentary endoparasites that can infect more than 3000 plant species. Root-knot nematodes cause an estimated $100 billion annual loss worldwide. For successful establishment of the root-knot nematode in its host plant, it causes dramatic morphological and physiological changes in plant cells. The expression of some plant genes is altered by the nematode as it establishes its feeding site.
Results: We examined the expression of soybean (Glycine max) genes in galls formed in roots by the root-knot nematode, Meloidogyne incognita, 12 days and 10 weeks after infection to understand the effects of infection of roots by M. incognita. Gene expression was monitored using the Affymetrix Soybean GeneChip containing 37,500 G. max probe sets. Gene expression patterns were integrated with biochemical pathways from the Kyoto Encyclopedia of Genes and Genomes using PAICE software. Genes encoding enzymes involved in carbohydrate and cell wall metabolism, cell cycle control and plant defense were altered.
Conclusions: A number of different soybean genes were identified that were differentially expressed which provided insights into the interaction between M. incognita and soybean and into the formation and maintenance of giant cells. Some of these genes may be candidates for broadening plants resistance to root-knot nematode through over-expression or silencing and require further examination.

AB For genetic analysis of the genus Allium, which is composed of diverse species, we acquired 50 transferable and polymorphic microsatellite markers from A. sativum and tested them for transferability in five Album species. Among the 50 simple sequence repeat (SSR) loci, the dinucleotide motif was the most prevalent, with a ratio of 50% (25/50), and (GT)n was more frequent than (GA)n within the dinucleotide motif. The average number of amplified alleles ranged from 1.452 to 1.910 and the accessions of A. tuberosum had a maximum of 4.8 alleles per accession with the GB-AS-104 SSR marker. Whereas A. porrum belonging to the Allium section revealed 73.0% transferability, A. altaicum and A. fistulosum appertaining to different sections showed low transferability, with a ratio of 47.6% and 48.0%, respectively. The phylogenetic results for these SSR markers did not deviate from previous classifications of the genus Allium. As the rate of successful amplification of SSR markers generally correlates with genetic distance, these SSR markers are potentially useful in the analysis of genetic relationships between or within Allium species.

AB Internalization of cell surface receptors, followed by either recycling back to the plasma membrane or degradation, is crucial for receptor homeostasis and signaling. The plant brassinosteroid ( BR) receptor, BRASSINOSTEROID INSENSITIVE 1 (BRI1), undergoes constitutive cycling between the plasma membrane and the internal membranes. We show that protein phosphatase 2A (PP2A) dephosphorylated BRI1 and that Arabidopsis thaliana rcn1, a mutant for a PP2A subunit, caused an increase in BRI1 abundance and BR signaling. We report the identification, in A. thaliana, of a suppressor of bri1, sbi1, which caused selective accumulation of BR-activated BRI1, but not the BR co-receptor BAK1 (BRI1-ASSOCIATED KINASE 1), in the membranous compartment. SBI1 mRNA was induced by BRs, and SBI1 encodes a leucine carboxylmethyltransferase (LCMT) that methylated PP2A and controlled its membrane-associated subcellular localization. We propose that BRs increase production of SBI1, which methylates PP2A, thus facilitating its association with activated BRI1. This leads to receptor dephosphorylation and degradation, and thus to the termination of BR signaling.

AB Reassortment allows multicomponent viruses to exchange genome segments, a process well-documented in the vertebrate- and arthropod-infecting members of the family Bunyaviridae but not between distinct species of the plant- and insect-infecting members of the genus Tospovirus. Genome sequence comparisons of a virus causing severe tospovirus-like symptoms in Florida tomato with Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus (TCSV) demonstrated that reassortment has occurred, with the large (L) and small (S) RNAs coming from GRSV and the medium (M) RNA coming from TCSV (i.e. L(G)M(T)S(G)). Neither parental genotype is known to occur in the U.S. suggesting that L(G)M(T)S(G) was introduced as a reassortant. L(G)M(T)S(G) was transmitted by western flower thrips (Frankliniella occidentalis [Pergandep]), and was not able to overcome the Sw5 resistance gene of tomato. Our demonstration of reassortment between GRSV and TCSV suggests caution in defining species within the family Bunyaviridae based on their ability to reassort. Published by Elsevier Inc.

AB Foot-and-mouth disease (FMD) is one of the most serious threats to the livestock industry. Despite the availability of a vaccine, recent outbreaks in disease-free countries have demonstrated that development of novel FMD control strategies is imperative. Here we report the identification and characterization of bovine (bo) interferon lambda 3 (IFN-lambda 3), a member of the type III IFN family. Expression of bolFN-lambda 3 using a replication-defective human adenovirus type 5 vector (Ad5-bolFN-lambda 3) yielded a glycosylated secreted protein with antiviral activity against FMD virus (FMDV) and vesicular stomatitis virus in bovine cell culture. Inoculation of cattle with Ad5-bolFN-lambda 3 induced systemic antiviral activity and up-regulation of IFN stimulated gene expression in multiple tissues susceptible to FMDV infection. Our results demonstrate that the type III IFN family is conserved in bovines and bolFN-lambda 3 has potential for further development as a biotherapeutic candidate to inhibit FMDV or other viruses in cattle.

AB Three isolates (AL09-71, AL09-72, and AL09-73) of Aeromonas hydrophila were cultured from infected channel catfish Ictalurus punctatus during a disease outbreak in west Alabama, USA, in August 2009. Sequence analysis of the 16S-23S rDNA intergenic spacer region (ISR), cpn60, gyrB, and rpoD genes of the 3 strains revealed that the 3 strains were closely related to each other, sharing 97 to 99% nucleotide sequence similarities. However, ISR sequences of the 3 isolates from 2009 shared only 64% nucleotide sequences with AL98-C1B, a 1998 isolate of A. hydrophila cultured from diseased fish in Alabama. Sequences of cpn60, gyrB, and rpoD from the 3 isolates from 2009 shared 91 to 95% homologies with AL98-C1B. Based on both LD(50) and LD(95) values of intraperitoneal injection assays, the virulences of the 3 isolates from 2009 were not significantly different from each other, but were at least 200-fold more virulent than AL98-C1B, indicating that the 3 west Alabama isolates of A. hydrophila from 2009 were highly virulent to channel catfish.

AB To reach the goals laid out by the U. S. Government for displacing fossil fuels with biofuels, high-biomass sorghum is well-suited to achieving this goal because it requires less water per unit dry biomass and can produce very high biomass yields. In order to make biofuels economically competitive with fossil fuels it is essential to maximize production efficiency throughout the system. The goal of this study was to use remote sensing technologies to optimize the yield and harvest logistics of high-biomass sorghum with respect to production costs based on spatial variability within and among fields. Specific objectives were to compare yield to aerial multispectral imagery and develop predictive relationships. A 19.2-ha high-biomass sorghum field was selected as a study site and aerial multispectral images were acquired with a four-camera imaging system on July 17, 2009. Sorghum plant samples were collected at predetermined geographic coordinates to determine biomass yield. Aerial images were processed to find relationships between image reflectance and yield of the biomass sorghum. Results showed that sorghum biomass yield in early August was closely related (R(2) = 0.76) to spectral reflectance. However, in the late season the correlations between the biomass yield and spectral reflectance were not as positive as in the early season. The eventual outcome of this work could lead to predicted-yield maps based on remotely sensed images, which could be used in developing field management practices to optimize yield and harvest logistics.

TI Biology and preliminary host range of Hydrotimetes natans Kolbe
(Coleoptera: Curculionidae), a natural enemy candidate for biological
control of Cabomba caroliniana Gray (Cabombaceae) in Australia
SO AUSTRALIAN JOURNAL OF ENTOMOLOGY
LA English
DT Article
DE Bagoini; biocontrol; cabomba; host specificity; invasive aquatic plant
AB Cabomba caroliniana, otherwise known as cabomba, is a submerged, rooted macrophyte with heavily dissected leaves that produces flowers that extend above the water surface. It has been disseminated around the world by aquarium traders and enthusiasts, and has become a noxious weed in numerous countries, including Australia, where it often produces dense monospecific stands. It is considered native to southern parts of North and South America, and is a common plant in floodplain streams and lakes in north-east Argentina. Because of the lack of alternative control methods, a search for biological control agents was initiated in 2003. The most promising natural enemy found during surveys of C. caroliniana in Argentina was the aquatic weevil Hydrotimetes natans. The entire life cycle is completed on the plant, primarily underwater, except when the adults climb onto emergent flowers to mate. Larvae mine the stems, pupal cases are constructed in the leaf axils where the petiole joins the stem, and adults feed on the leaves and the stems, primarily at the growing tips. Field surveys of C. caroliniana and other submerged plant species, as well as results from preliminary laboratory host range trials suggest that the weevil is specific to cabomba. Adults were found only on other plant species when intertwined with C. caroliniana in the field and did not move onto other plant species in aquaria trials. The distribution of the larvae in the field was studied in relation to depth and plant size. No preferences for stem width or plant length were found, although a significant portion of the larval mines were located near the root crown of the plant. This information on the host specificity and biology of H. natans in its native range may guide researchers studying the laboratory fundamental host range and determining the potential effectiveness of the weevil for biological control of cabomba in its introduced range.

AB During an examination of type material of the New World endomychid genus Bystus Guerin-Meneville (Anamorphinae), the type series of Alexia hirtula Kirsch from Peru was found to contain a mixture of different taxa, none of which belong to the genus Bystus, the subfamily Anamorphinae, or even the family Endomychidae. Alexia hirtula is transferred to Delphastus Casey (Coccinellidae: Microweiseinae: Serangiini), establishing the new combination, Delphastus hirtulus (Kirsch), and a lectotype is designated. Of the three paralectotypes, one appears to be conspecific with the lectotype, one is identified as an undescribed species of Microscymnus Champion (Coccinellidae: Cryptognathini), and one, a partial specimen lacking the head, pronotum, and one elytron, is identified as a species of Leiodidae in the tribe Scotocryptini, probably Aglyptinus Cockerell. A diagnosis and redescription of D. hirtulus is provided, and Gordon's (1994) key to Delphastus is modified to accommodate the newly transferred species. The historical classification of D. hirtulus is discussed along with characters justifying its revised placement.

AB Background: Milkweeds (Asclepias L.) have been extensively investigated in diverse areas of evolutionary biology and ecology; however, there are few genetic resources available to facilitate and compliment these studies. This study explored how low coverage genome sequencing of the common milkweed (Asclepias syriaca L.) could be useful in characterizing the genome of a plant without prior genomic information and for development of genomic resources as a step toward further developing A. syriaca as a model in ecology and evolution.
Results: A 0.5x genome of A. syriaca was produced using Illumina sequencing. A virtually complete chloroplast genome of 158,598 bp was assembled, revealing few repeats and loss of three genes: accD, clpP, and ycf1. A nearly complete rDNA cistron (18S-5.8S-26S; 7,541 bp) and 5S rDNA (120 bp) sequence were obtained. Assessment of polymorphism revealed that the rDNA cistron and 5S rDNA had 0.3% and 26.7% polymorphic sites, respectively. A partial mitochondrial genome sequence (130,764 bp), with identical gene content to tobacco, was also assembled. An initial characterization of repeat content indicated that Ty1/copia-like retroelements are the most common repeat type in the milkweed genome. At least one A. syriaca microread hit 88% of Catharanthus roseus (Apocynaceae) unigenes (median coverage of 0.29x) and 66% of single copy orthologs (COSII) in asterids (median coverage of 0.14x). From this partial characterization of the A. syriaca genome, markers for population genetics (microsatellites) and phylogenetics (low-copy nuclear genes) studies were developed.
Conclusions: The results highlight the promise of next generation sequencing for development of genomic resources for any organism. Low coverage genome sequencing allows characterization of the high copy fraction of the genome and exploration of the low copy fraction of the genome, which facilitate the development of molecular tools for further study of a target species and its relatives. This study represents a first step in the development of a community resource for further study of plant-insect co-evolution, anti-herbivore defense, floral developmental genetics, reproductive biology, chemical evolution, population genetics, and comparative genomics using milkweeds, and A. syriaca in particular, as ecological and evolutionary models.

TI A Robust, Simple Genotyping-by-Sequencing (GBS) Approach for High
Diversity Species
SO PLOS ONE
LA English
DT Article
ID MAIZE GENOME; POPULATION; GENERATION; ASSOCIATION; PLANT; MAP
AB Advances in next generation technologies have driven the costs of DNA sequencing down to the point that genotyping-by-sequencing (GBS) is now feasible for high diversity, large genome species. Here, we report a procedure for constructing GBS libraries based on reducing genome complexity with restriction enzymes (REs). This approach is simple, quick, extremely specific, highly reproducible, and may reach important regions of the genome that are inaccessible to sequence capture approaches. By using methylation-sensitive REs, repetitive regions of genomes can be avoided and lower copy regions targeted with two to three fold higher efficiency. This tremendously simplifies computationally challenging alignment problems in species with high levels of genetic diversity. The GBS procedure is demonstrated with maize (IBM) and barley (Oregon Wolfe Barley) recombinant inbred populations where roughly 200,000 and 25,000 sequence tags were mapped, respectively. An advantage in species like barley that lack a complete genome sequence is that a reference map need only be developed around the restriction sites, and this can be done in the process of sample genotyping. In such cases, the consensus of the read clusters across the sequence tagged sites becomes the reference. Alternatively, for kinship analyses in the absence of a reference genome, the sequence tags can simply be treated as dominant markers. Future application of GBS to breeding, conservation, and global species and population surveys may allow plant breeders to conduct genomic selection on a novel germplasm or species without first having to develop any prior molecular tools, or conservation biologists to determine population structure without prior knowledge of the genome or diversity in the species.

AB Neolasioptera aculeatae Gagne (Diptera: Cecidomyiidae) is described as a new species from stem swellings on Parkinsonia aculeata L. (Leguminosae) in NW Argentina. The new species appears to be a good candidate for the biological control of its host in Australia, where the plant was accidentally introduced and is currently a serious pest. The species is shown to be distinct from its 64 Neotropical congeners. A preliminary key to these species is offered that can be adapted as more work is done on Neolasioptera.

AB Understanding autonomic nervous system functioning, which mediates behavioral and physiological responses to stress, offers great potential for assessing farm animal stress and welfare. Evaluation of heart rate variability (HRV) and blood pressure variability (BPV), using time and frequency domain analyses may provide a sensitive and reliable measure of affective states and stress-mediated changes in sympathetic and parasympathetic tones. The aim of this research was to define low (LF) and high frequency (HF) power spectral ranges using pharmacological autonomic blockade, and to examine HRV and BPV parameter changes in response to atropine and propranolol in swine. Ten. 13-week old, barrows (n = 6) and gilts (n = 4) underwent surgery to place an intra-cardiac electrode and a blood pressure catheter attached to a biotelemetric transmitter; pigs had a 3-week recovery period prior to data collection. Each pig was subjected to administration of 4 intravenous (iv.) drug treatments: a control treatment, 3 mL of saline, and 3 blockade treatments; 0.1 mg/kg of atropine, 1.0 mg/kg of propranolol, and.1 mg/kg of atropine together with 1.0 mg/kg of propranolol. All treatments were delivered by injection in the jugular vein with a minimum of 48 h between individual treatments. Behavior, ECG and blood pressure data were recorded continuously for a total of 1 h, from 30 min pre-injection to 30 min post-injection. For data analyses, two 512-beat intervals were selected for each treatment while the pig was lying and inactive. The first interval was selected from the pre-injection period (baseline), and the second was selected between 10 and 30 min post-injection. Time and frequency domain (power spectral density) analyses were performed on each data interval. Subsequent, LF and HF bands from the power spectral densities were defined based on general linear and regression analyses. The HRV and BPV were computed with a covariate (baseline) factorial analysis of treatment by sex interaction, and day of injection, with mixed models and Tukey's post-hoc tests. The best-fit range for LF was 0.0-0.09 Hz, and HF was 0.09-2.0 Hz (r(2): 0.41 and 0.43, respectively). Propranolol and saline injections led to a greater overall total power and overall higher inter-beat interval. HF and LF power. Atropine led to a dominant sympathovagal balance of the cardiac activity in pigs. In addition, atropine led to an increase in LF power of both systolic and diastolic blood pressures in gilts suggesting vagal tone mediation of BPV. The understanding of autonomic regulation of HRV and BPV in domestic swine facilitates our ability to detect and quantify stress responses, and broadens its application in assessing farm animal welfare.

AB The aim of this study is to elucidate whether insulin acts differentially within the central nervous system (CNS) of two types of commercial chicks to control ingestive behavior. Male layer and broiler chicks (4-day-old) were intracerebroventricularly (ICV) injected with saline or insulin under satiated and starved conditions. Feed intake was measured at 30, 60 and 120 min after treatment. Secondly, blood and hypothalamus were collected from both chick types under ad libitum feeding and fasting for 24 h. Plasma insulin concentration was measured by time-resolved fluoro-immunoassay. Hypothalamic insulin receptor mRNA expression levels were measured by quantitative RT-PCR. The ICV injection of insulin significantly inhibited feed consumption in layer chicks when compared with saline (P<0.05), but not broiler chicks (P>0.1). Plasma insulin concentration of both chick types significantly decreased following 24 h of fasting, while insulin concentrations in the broiler chicks were significantly higher compared to the layers fed under ad libitum conditions. Hypothalamic insulin receptor mRNA expression levels were significantly lower (P<0.05) in broiler chicks than in layer ones under ad libitum feeding. Feed deprivation significantly decreased insulin receptor mRNA levels in layer chicks (P<0.01), but not in broiler chicks (P>0.1). Moreover, plasma insulin concentrations correlated negatively with hypothalamic insulin receptor protein expression in the two types of chicks fed ad libitum (P<0.05). These results suggest that insulin resistance exists in the CNS of broiler chicks, possibly due to persistent hyperinsulinemia, which results in a down-regulation of CNS insulin receptor expression compared to that in layer chicks.

AB Plants are attacked by pathogens representing diverse taxonomic groups, such that genes providing multiple disease resistance (MDR) are expected to be under positive selection pressure. To address the hypothesis that naturally occurring allelic variation conditions MDR, we extended the framework of structured association mapping to allow for the analysis of correlated complex traits and the identification of pleiotropic genes. The multivariate analytical approach used here is directly applicable to any species and set of traits exhibiting correlation. From our analysis of a diverse panel of maize inbred lines, we discovered high positive genetic correlations between resistances to three globally threatening fungal diseases. The maize panel studied exhibits rapidly decaying linkage disequilibrium that generally occurs within 1 or 2 kb, which is less than the average length of a maize gene. The positive correlations therefore suggested that functional allelic variation at specific genes for MDR exists in maize. Using a multivariate test statistic, a glutathione S-transferase (GST) gene was found to be associated with modest levels of resistance to all three diseases. Resequencing analysis pinpointed the association to a histidine (basic amino acid) for aspartic acid (acidic amino acid) substitution in the encoded protein domain that defines GST substrate specificity and biochemical activity. The known functions of GSTs suggested that variability in detoxification pathways underlie natural variation in maize MDR.

AB Many land managers are interested in maintaining or restoring plant communities that contain Oregon white oak (OWO, Quercus garryana), yet there is relatively little information available about the species' growth rates and survival to guide management decisions. We used two studies to characterize growth (over multi-year periods and within individual years) and to evaluate the main factors that affect growth and survival. The objective of the first study was to revise the OWO components of the Forest Vegetation Simulator (FVS), a widely-used growth model. We first compiled a large database on growth and survival to develop equations to revise FVS. Diameter growth and survival over multi-year periods were strongly affected by stand density, the competitive position of the tree, tree size, and site productivity. The height growth potential of OWO was predicted from site productivity, stand density and tree size. In the second study, intra-annual patterns of OWO growth were evaluated by precisely measuring stem diameters with band dendrometers. OWO experienced two periods of stem expansion, with the first period likely representing growth (the production of new wood and bark) and the second representing stem rehydration in the fall and winter. As in the first study, growth was strongly affected by the level of competition around each tree. Our results show the sensitivity of Oregon white oak to competition and highlight the need to restore low stand densities in many cases to improve growth and the likelihood of survival.

AB Biologic samples from 18 (12 female, 6 male) Siberian hamsters (Phodopus sungorus) representing an aged colony (17 to 27 mo) were examined. Values for CBC and serum biochemical parameters were determined, and macroscopic and microscopic pathologic evaluations were performed. Blood urea nitrogen levels were significantly higher in male (54.2 +/- 14 mg/dL) compared with female (35.3 +/- 22 mg/dL) hamsters and correlated histologically with a higher incidence of chronic glomerulonephropathy in males (5 of 6 males; 0 of 12 females). All 18 hamsters had histologic evidence of follicular mite infestation. Half (6 of 12) of the female hamsters showed cystic rete ovarii. Other histologic findings included thymic or thyroid branchial cysts (3 of 18), focal enteritis (2 of 18), and single cases of hepatic hemangiosarcoma, renal adenoma, subcutaneous mast cell tumor, cutaneous sebaceous adenoma, cutaneous trichofolliculoma, squamous papilloma of the nonglandular stomach, epididymal cholesteatoma, pyometra, and pituitary craniopharyngeal cyst. This study is the first published report of hematologic and serum chemical values for any population of Siberian hamsters and the first published report showing a potential male predisposition for chronic progressive glomerulonephropathy and a potential female predisposition for cystic rete ovarii.

AB This study applied Sulfite Pretreatment to Overcome Recalcitrance of Lignocelluloses (SPORL) to evaluate the potential of mountain pine beetle-killed lodgepole pine for ethanol production using conventional Saccharomyces cerevisiae without hydrolysate detoxification. The results indicate that the beetle-killed trees are more susceptible to SPORL pretreatment than live trees in addition to having enriched glucan and mannan content as reported in the literature. Ethanol yields of 200 and 250 L/metric ton wood were achieved from a live tree and a dead tree (four years after infestation) without process optimization. Ethanol yield of 220 L/metric ton of wood was obtained from a downed tree with more advanced decomposition, which is approximately 10% more than that from a corresponding live tree. Process mass and energy balance analyses suggest that net ethanol energy output (before distillation, lignin energy excluded) from the decomposing tree was approximately 3.2 GJ/metric ton wood, which is 23% more than that from a corresponding live tree. The study demonstrated the robustness of the SPORL process and the utility of beetle-killed trees for cellulosic ethanol production even after many years post mortality.

AB Pilot data indicate that wood chip pretreatment with oxalic acid reduced the specific energy required to make thermomechanical pulp. A combined oxalic acid/bisulfite treatment resulted in 21% refiner energy savings and 13% increase in brightness for aspen. A low level of oxalic acid treatment was effective for spruce. Energy savings of 30% was observed with no significant change in strength properties. Adding bisulfite did not significantly increase the brightness of the spruce pulp. For pine, the optimum treatment was a moderate level of oxalic acid, which resulted in 34% energy savings and an increase in strength properties. For all of these treatments 1-3 w/w % carbohydrates were recovered, which can be fermented to produce ethanol. The extract sugar solution contained significant quantities of arabinose.

AB Value Prior to Pulping (VPP) is a novel biorefining concept for pulp mills that includes hydrolysis extraction of hemicellulose wood sugars and acetic acid from pulpwood prior to pulping. The concept involves conversion of wood sugars via fermentation to fuel ethanol or other chemicals and the use of remaining solid wood material in the pulping process. This paper provides an overview of the methods and results from analysis of the concept as a hypothetical business investment at a pulp and paper mill equipped for making thermomechanical pulp (TMP).

AB This study was conducted to evaluate the effect of oxalic acid (OA) pretreatment on carbohydrates released from rice straw particles and wood chips. The results showed that OA treatment accelerated carbohydrates extraction from rice straw particles and wood chips. OA pretreatment dramatically increased the amount of carbohydrates extracted, up to 24 times for wood chips and 2.3 times for rice straw particles. Sugars released from the OA-treated rice straw particles and wood chips increased with increasing treatment temperature and duration. OA treatment also improved the primary physical properties of rice straw particleboard and wooden medium density fiberboard (MDF), except for the mechanical strength of MDF. Carbohydrates extracted from rice straw particles and wood chips could be a potential sustainable resource for biofuel or biobased chemicals.

TI Rheology and extrusion of high-solids biomass
SO TAPPI JOURNAL
LA English
DT Article
ID WET
AB Economical biorefining of lignocellulosic biomass (LCB) requires processing high-solids particulate streams. We have developed new techniques and testing protocols to measure the rheological properties of high-solids LCB using a modified torque rheometer (TR). The flow field in the TR is similar to that of a twin-screw extruder and for modeling purposes can be adequately represented as a dual-Couette viscometer. Our experiments show that LCB exhibits Bingham plastic behavior with very large yield stresses. We observe that in the initial stages of mixing, torque values are extremely large and erratic. During this period, considerable particle-size reduction takes place with correspondingly large energy consumption. We show that the addition of a rheological modifier (e. g., carboxymethyl cellulose) reduces biomass apparent viscosity and mixing energy requirements. We take advantage of this effect to further investigate the viability of continuous processing by extrusion.

AB We examined the role of chemical signals in sex attraction of pear psylla, Cacopsylla pyricola (Forster), assessing the response of summerform male and female psyllids to male- and female-produced volatile chemicals. Male psyllids were attracted to odors from live females and pentane extracts of females. Extracts of females were as attractive to males as live females, suggesting that the female-produced volatile chemicals responsible for male attraction might be isolated by extracting females with pentane. Females were not attracted to odorants from live females and tended to avoid odorants from extracts of females. Furthermore, summerform males and females were not attracted or repelled by male-produced odorants from live males or extracts of males. Results of olfactometer assays using male summerform C. pyricola are consistent with results from earlier studies with the winterform morphotype of this species.

TI Release of Native and Amended Boron From Arid Zone Soils After Varying
Incubation Times
SO SOIL SCIENCE
LA English
DT Article
DE Adsorption; desorption
ID DESORPTION
AB In this study, we evaluated the boron (B) release from soils containing elevated native B and examined the extent to which incubation time affected B release. Five soils varying in initial pH and clay content were selected for the study. The soils were spiked with five varying doses of B as H3BO3 (0-100 mg B kg(-1)) and equilibrated for a total of 5 months at field capacity water content. The soils were incubated in a temperature-controlled room at 25 degrees C. At monthly intervals, the soils were thoroughly mixed and subsamples were removed. The subsamples were extracted with diethylenetriaminepentaacetic acid-sorbitol, boiling water, and 0.1 M NaCl to provide various B extraction protocols. Boron desorption decreased as a function of time for at least some of the extractions and treatments for all five soils. This is consistent with published literature that added B becomes less extractable with increased incubation time. Comparison between the three extractants revealed no statistically significant differences in amounts of adsorbed B for three of the soils. For the two other soils, the order of desorbed B amount was hot water soluble < 0.1 M NaCl extractable G diethylenetriaminepentaacetic acidYsorbitol extractable. The decrease in B release with respect to incubation time approached zero for all five soils for most of the extractant solutions, as evidenced by slopes that were not statistically significantly different from zero at the 95% level of confidence for almost all treatments of all three extractions. This result suggests that a 5-month incubation is adequate to obtain an accurate assessment of the amount of B available for release. Because the decrease in extractable B with time for four of the soils is not large, a very good indication of extractable soil B can be obtained from a 1-month incubation study.

AB In this study, stress-relaxation performance of HDPE-based injection-molded composites containing four types of natural fibers (i.e., wood flour, rice hulls, newsprint, and kenaf fiber) at 25 and 50 wt% contents, and the effect of prescribed strain levels were investigated. The results indicated that incorporating more filler causes lower relaxation values and rates, and stress retention and prescribed strain level were reversely correlated. Among the studied filler types, wood flour and kenaf fiber presented more similar behaviors, whereas newsprint resembled rice hulls performance. Strain-time superposition was applied to the experimental data. Due to complex rheological behavior of the studied composites, single horizontal shifting method, with respect to strain levels, was found to be inadequate to satisfactorily superpose data.

AB Prion diseases or transmissible spongiform encephalopathies (TSEs) of animals include scrapie of sheep and goats; transmissible mink encephalopathy (TME); chronic wasting disease (CWD) of deer, elk and moose; and bovine spongiform encephalopathy (BSE) of cattle. The emergence of BSE and its spread to human beings in the form of variant Creutzfeldt-Jakob disease (vCJD) resulted in interest in susceptibility of cattle to CWD, TME and scrapie. Experimental cross-species transmission of TSE agents provides valuable information for potential host ranges of known TSEs. Some interspecies transmission studies have been conducted by inoculating disease-causing prions intracerebrally (IC) rather than orally; the latter is generally effective in intraspecies transmission studies and is considered a natural route by which animals acquire TSEs. The "species barrier" concept for TSEs resulted from unsuccessful interspecies oral transmission attempts. Oral inoculation of prions mimics the natural disease pathogenesis route whereas IC inoculation is rather artificial; however, it is very efficient since it requires smaller dosage of inoculum, and typically results in higher attack rates and reduces incubation time compared to oral transmission. A species resistant to a TSE by IC inoculation would have negligible potential for successful oral transmission. To date, results indicate that cattle are susceptible to IC inoculation of scrapie, TME, and CWD but it is only when inoculated with TME do they develop spongiform lesions or clinical disease similar to BSE. Importantly, cattle are resistant to oral transmission of scrapie or CWD; susceptibility of cattle to oral transmission of TME is not yet determined.

AB Primary tumors of serosal surfaces are uncommon in veterinary medicine. Mesothelial neoplasms can be benign or malignant, and are classified as predominantly epitheloid, mixed (biphasic), or fibrous (spindle cell, fibrosarcomatous), with fibrous mesotheliomas reported least in domestic species. A 9-year-old Domestic Shorthair cat presented on emergency with a brief history of weakness and lethargy. On presentation, the cat was semicomatose, hypothermic, and hypotensive with a markedly distended abdomen. Approximately 1 liter of serosanguineous fluid was removed via abdominocentesis. Diagnostic imaging and cytologic evaluation of fine-needle aspirates were suggestive of neoplasia, and the cat was subsequently euthanized. At necropsy, the omentum was contracted cranially into an irregular lobular mass that surrounded the stomach and proximal intestinal tract, and focally infiltrated the spleen. Both visceral and parietal peritoneal surfaces were thickened and contained off-white friable material and occasionally firm fibrous plaques. Microscopically, serosal surfaces were expanded by neoplastic spindle cells, which were often accompanied by moderate to abundant fibrous stroma. Neoplastic cells had varying degrees of immunoreactivity for cytokeratin, vimentin, desmin, and smooth muscle actin, which was consistent with the diagnosis of mesothelioma.

AB Fusarium tucumaniae and F. virguliforme are the primary etiological agents of sudden-death syndrome (SDS) of soybean in Argentina and the United States, respectively. Five isolates of F. tucumaniae and four isolates of F. virguliforme were tested for relative aggressiveness to soybean, using a toothpick inoculation method and two versions of a soil infestation inoculation method. Partially resistant soybean cultivar RA629 and susceptible cultivar A6445RG were inoculated separately with each of the nine isolates. Two experiments for each inoculation method were performed. Analysis of variance identified a significant three-way interaction of soybean cultivar*experiment*SDS pathogen (P = 0.01) using the different methods. When the two soil infestation methods were used, F. virguliforme was more aggressive than F. tucumaniae; however, when using the toothpick method, isolates of F. virguliforme and F. tucumaniae were equally aggressive. Although all three methods discriminated levels of partial resistance of the genotypes to SDS, results of the present study indicated that soil inoculations with sorghum infested grain represent the best method for evaluating soybean cultivar resistance to SDS. The existence of interactions among the host, pathogen and environmental conditions highlights the need for additional studies to improve the reproducibility of tests for screening soybean germplasm for resistance to SDS.

AB Singhiella simplex (Singh) (Hemiptera: Aleyrodidae) is a newly invasive pest of several species of Ficus plants in the United States. Very little is known about its biology and life history. Here, we studied its development and reproduction at 15, 20, 25, 27, 30, and 35 degrees C. No immatures survived the 35 degrees C treatment. Stage-specific duration times are presented for the other temperatures. Total duration of immature stages varied from 97.1 d at 15 degrees C to 25.2 d at 30 degrees C. Linear functions were used to describe development rates for eggs, instars and pupal stages. Total immature development also was modeled using a nonlinear Briere-1 function: r(T) = aT(T - T(0)) root T(L) - T, where r(T) is developmental rate at temperature (T), a = 0.0000146, T(0) = 7.3120084 and T(L) = 45.9512202 (constant, lower developmental threshold, and lethal temperature, respectively). The thermal requirement for development from eggs to pupae was estimated to be 487.8 degree-days. S. simplex reproduction was highest at 27 degrees C, where R(0), GRR, T, r, lambda, and DT were 23.114 female/female, 24.25 female/female, 31.413 d, 0.099 female/female/d, 1.105 female/female/d, and 6.93 d, respectively. The combined effect of temperature and female adult age on daily oviposition rate was modeled using the Enkegaard equation: eggmean = (p + qT) d exp(-wTd), where T is temperature. Parameter estimates were p = -30.21, q = 2.62, and w = 0.034. Duration of female adulthood was 8 d at 15 degrees C, significantly longer than 2.5-4.2 d at the higher temperatures. At 25 and 27 degrees C, lifetime fecundity per female averaged 37.9 and 46.2, respectively.

AB We investigated how environmental variables influence development and survivorship of Boreioglycaspis melaleucae Moore (Hemiptera: Psyllidae) by quantifying life history characteristics of adults, eggs, and nymphs when held at eight constant temperatures, four relative humidities, and on plants that differed in foliar terpenoid profiles. There is insufficient evidence to conclude that terpenoid profiles or humidity influence B. melaleucae development. Although longevity of adult psyllids is greater on plants that contain E-nerolidol versus viridiflorol profiles, this does not translate to a longer ovipositional period or increased fecundity. Similarly, humidity treatments had a limited and inconsistent effect on B. melaleucae developmental rates and nymphal survivorship. In contrast, developmental rates increased linearly with increasing temperature to an optimum 25 degrees C, whereas greater temperatures caused total developmental rates to decrease. Temperature also affected nymphal survivorship, with no individuals completing development below 10 or above 30 degrees C. Mean maximum daily temperatures in southern Florida commonly exceeded 30 degrees C, with maximum temperatures ranging from 30 to 35 degrees C (in Broward Co.) during 138 d in 2006. Therefore, we conclude that lethal upper temperature thresholds will limit population growth rates during summer.

AB Feeding attractants for moths are useful as survey tools to assess moth species diversity and for monitoring of the relative abundance of certain pest species. We assessed the relative breadth of attractiveness of two such lures to moths, at sites with varied habitats during 2006. Eighty-six of the 114 species of Lepidoptera captured were in traps baited with acetic acid plus 3-methyl-1-butanol (AAMB), a moth lure that is based on the odor chemistry of fermented molasses baits. Fifty-two of the 114 species were trapped with a floral odorant lure comprised of phenylacetaldehyde, beta-myrcene, methyl salicylate, and methyl-2-methoxy benzoate. Preference for one lure type was statistically supported for 10 species of moths: seven to the AAMB lure and three to the floral lure. To gain better information on lure preference, 10 pairs of traps baited with the same lures were maintained in a single habitat type (riparian) during 2008. Sixty-eight of 89 species captured were in traps baited with AAMB, and 43 were in traps baited with the floral lure. Preference for a lure type was statistically supported for 39 of the 89 species of moths trapped; 32 to the AAMB lure and seven to the floral lure. Both of these lures hold advantages for trapping different types of moths, and both lures might be used in a complementary way to sample moth biodiversity.

AB Lepidopteran stem borers were collected from switchgrass, Panicum virgatum L., tillers showing symptoms of infestation at seven locations in Illinois and Iowa, with additional observations made on larval and adult activity. Blastobasis repartella (Dietz) (Coleophoridae), whose only known host is switchgrass, was common in plots grown for >5 yr, whereas the polyphagous stalk borer, Papaipema nebris (Guenee) (Noctuidae), was abundant in newly established (i.e., first- and second-year) switchgrass. Haimbachia albescens Capps (Crambidae) was collected from two locations in Illinois, making switchgrass the first known host for this species. Entry holes made by B. repartella and H. albescens were usually 1-2 cm above the soil surface, precluding discrimination between these species based on external appearance of damage. Although P. nebris often entered stems within 5 cm of the soil surface, they also seemed to move between stems and were the only species entering stems at heights > 15 cm. Adults of B. repartella were active on and above the switchgrass canopy by 2130 hours, with peak activity at approximate to 0230 hours. Activity of B. repartella adults seemed greatly reduced on one night with relatively cool temperatures and low wind speeds. Data from switchgrass and giant ragweed, Ambrosia trifida L., suggest P. nebris larvae move out of switchgrass during July in search of hosts with larger diameter stems, although by then hosts such as corn, Zea mays L., or Miscanthus spp. may have outgrown the potential for serious damage. However, switchgrass could contribute to greater adult populations of P. nebris if thick-stemmed hosts such as giant ragweed are not managed.

AB The corn leafhopper, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae), is a vector of three maize, Zea mays L., pathogens that have become limiting factors for maize production in some areas of the Americas. Insect feeding plays an important role in vector acquisition and inoculation of pathogens and hence the disease spread. Thus, we sought to understand the different probing and stylet penetration activities performed by this insect while feeding on maize plants, with the ultimate goal of characterizing potential sources of insect resistance in maize. Using electrical penetration graph technology, six distinct waveforms were characterized and correlated with major probing activities of D. maidis via transmission of corn stunt spiroplasma and excretion of honeydew as markers. Major waveforms comprise stylet pathway (waveform 1), active ingestion in nonsieve elements (waveform 2), nonvascular probing (waveform 3), phloem contact (waveform 4, the X wave), phloem ingestion (waveform 5), and oviposition (waveform 6). Our results support most previous findings with this species, and also indicate that some waveforms (2, 4, and 5) are related to biopotentials generated during probing, as was previously found for other hemipteran species. The most important finding from this work is that D. maidis ingests from phloem sieve elements more frequently and for longer durations than seen in previous research, probably due to longer observation periods used in this study. This work provides basic information relevant to the understanding of probing behavior of D. maidis and to the characterization of potential sources of insect-resistant maize.

AB Candidatus Liberibacter asiaticus (CLas) bacterium has been strongly implicated as the causative agent of huanglongbing (HLB), or citrus greening, which is currently the most devastating citrus disease worldwide. HLB is transmitted by the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), in a persistent manner. We used quantitative-polymerase chain reaction (PCR) to detect CLas in dissected organs of individual D. citri adults infected with HLB in the laboratory or collected from field-infected citrus trees in South Florida. The proportion of infected (CLas-positive) dissected organs was 47-70% for the salivary glands, 72-80% for the alimentary canal, and 79-97.5% for the rest of the insect body. Statistical analysis indicated that, in both field-and laboratory-infected D. citri, the proportion of infected salivary glands was significantly lower than that of other parts in the insect body. With field-collected psyllids, the relative copy number of CLas genomes, compared with psyllid genomic DNA in each sample, was significantly higher in both the salivary gland and alimentary canal compared with that in the rest of the insect body for both males and females. These results provide the first PCR confirmation of CLas in the alimentary canal and salivary glands of D. citri and strongly suggest that the salivary glands constitute an important transmission barrier to CLas in the psyllid vector. Our results also suggest that CLas may replicate or accumulate in both the alimentary canal and salivary glands of D. citri.

AB With the exception of an airplane equipped with nets, no method has been developed that successfully samples red imported fire ant, Solenopsis invicta Buren, sexuals in mating/dispersal flights throughout their potential altitudinal trajectories. We developed and tested a method for sampling queens and males during mating flights at altitudinal intervals reaching as high as approximate to 140 m. Our trapping system uses an electric winch and a 1.2-m spindle bolted to a swiveling platform. The winch dispenses up to 183 m of Kevlar-core, nylon rope and the spindle stores 10 panels (0.9 by 4.6 m each) of nylon tulle impregnated with Tangle-Trap. The panels can be attached to the rope at various intervals and hoisted into the air by using a 3-m-diameter, helium-filled balloon. Raising or lowering all 10 panels takes approximate to 15-20 min. This trap also should be useful for altitudinal sampling of other insects of medical importance.

AB The effects of colonization on host-seeking behavior of mosquitoes was examined by comparing attraction responses of newly colonized Aedes aegypti (L.) from field-collected eggs in Puerto Rico to that of the Gainesville (Florida) strain, originally from Orlando (Florida) and in colony since 1952. Females from the Orlando and the F(0) through F(10) generations of the Puerto Rico strain were evaluated using attractant odors in a triple-cage dual-port olfactometer. Two attractant sources were used: odors from the hand of a volunteer and a standard blend of L-lactic acid, acetone, and dimethyl disulfide. Convergence of the percentage of attraction responses occurred around the F(4)-F(6) generations of the Puerto Rico strain. Both the Orlando and Puerto Rico strains exhibited similar responses for tests with the remaining F(7)-F(10) generations. A temporal effect on mosquito responses was observed for both strains regardless of the attractant blend used in tests. This study indicates that Ae. aegypti host-seeking behavior changes significantly over the first four to six generations after introduction into the laboratory, whereas the field-collected strain increases in attraction response until it stabilizes at a new level.

AB The cDNA of a trypsin gene from Aedes (Ochlerotatus) taeniorhynchus (Weidemann) was cloned and sequenced. The full-length mRNA sequence (890 bp) for trypsin from Ae. taeniorhynchus (AetTryp1) was obtained, which encodes an open reading frame of 765 bp (i.e., 255 amino acids). To detect whether AetTryp is developmentally regulated, a quantitative real-time polymerase chain reaction was used to examine AetTryp1 mRNA expression levels in different developmental stages of Ae. taeniorhynchus. AetTryp1 was expressed at low levels in egg, larval, and pupal stages, but was differentially expressed in adult Ae. taeniorhynchus, with highest levels found in 5-d-old female adults when compared with teneral adults. In addition, AetTryp1 mRNA expression differed between sexes, with expression levels much lower in males. However, in both males and females, there was a significant increase in AetTryp1 transcription levels as age increased and peaked in 5-d-old adults. AetTryp1 expressed in 5-d-old female Ae. taeniorhynchus significantly increased after 30 min postblood feeding compared with the control. The AetTryp1 mRNA expression in 5-d-old female Ae. taeniorhynchus was affected by different concentrations of permethrin.

AB The presence or absence of the biting midge Culicoides sonorensis Wirth & Jones (Diptera: Ceratopogonidae), a primary vector of bluetongue viruses (genus Orbivirus, family Reoviridae, BTV) in North America, was assessed on ranches and farms across the Northern Great Plains region of the United States, specifically Nebraska, South Dakota, and North Dakota, as part of a 2-yr regional study of BTV exposure among cattle. Blacklight/suction trap samples totaling 280 2-night intervals were taken at 140 aquatic sites (potential larval habitat for C. sonorensis) on 82 livestock operations (ranches and farms) that span a south-to-north gradient of expected decreasing risk for exposure to BTV. In Nebraska, C. sonorensis populations were common and widespread, present at 15 of 18 operations. Of 32 operations sampled in South Dakota, seven of which were sampled in successive years, 18 were positive for C. sonorensis; 13 of 14 operations located west of the Missouri River were positive, whereas 13 of 18 operations east of the river were negative. Of 32 operations sampled in North Dakota, seven of which were sampled both years, 12 were positive for C. sonorensis. Six of eight operations located west and south of the Missouri River in North Dakota were positive, whereas 18 of 24 operations east and north of the river were negative for C. sonorensis. These data illustrate a well-defined pattern of C. sonorensis spatial distribution, with populations consistently present across Nebraska, western South Dakota, and western North Dakota; western South Dakota, and North Dakota encompass the Northwestern Plains Ecoregion where soils are nonglaciated and evaporation exceeds precipitation. In contrast, C. sonorensis populations were largely absent east of the Missouri River in South Dakota and North Dakota; this area comprises the Northwestern Glaciated Plains Ecoregion and Northern Glaciated Plains Ecoregion where surface soils reflect Wisconsinan glaciation and precipitation exceeds evaporation. In defining a well-demarcated pattern of population presence or absence on a regional scale, the data suggest that biogeographic factors regulate the distribution of C. sonorensis and in turn BTV exposure. These factors, ostensibly climate and soil type as they affect the suitability of larval habitat, may explain the absence of C. sonorensis, hence limited risk for exposure to BTV, across the eastern Northern Plains, upper Midwest, and possibly Northeast, regions of the United States.

AB In 2006-2007, stable flies, Stomoxys calcitrans (L.) (Diptera: Muscidae), were suspected of being enzootic vectors of West Nile virus (family Flaviviridae, genus Flavivirus, WNV) during a die-off of American white pelicans (Pelecanus erythrorhynchos Gmelin) (Pelecanidae) in Montana, USA. WNV-positive stable flies were observed feeding en masse on incapacitated, WNV-positive pelicans, arousing suspicions that the flies could have been involved in WNV transmission among pelicans, and perhaps to livestock and humans. We assessed biological transmission by infecting stable flies intrathoracically with WNV and testing them at 2-d intervals over 20 d. Infectious WNV was detected in fly bodies in decreasing amounts over time for only the first 6 d postinfection, an indication that WNV did not replicate within fly tissues and that stable flies cannot biologically transmit WNV. We assessed mechanical transmission using a novel technique. Specifically, we fed WNV-infected blood to individual flies by using a cotton swab (i.e., artificial donor), and at intervals of 1 min-24 h, we allowed flies to refeed on a different swab saturated with WNV-negative blood (i.e., artificial recipient). Flies mechanically transmitted viable WNV from donor to recipient swabs for up to 6 h postinfection, with the majority of the transmission events occurring within the first hour. Flies mechanically transmitted WNV RNA to recipient swabs for up to 24 h, mostly within the first 6 h. Given its predilection to feed multiple times when disturbed, these findings support the possibility that the stable fly could mechanically transmit WNV.

AB The cytogenetic characterization of the carrot genome (Daucus carota L., 2n = 18) has been limited so far, partly because of its somatic chromosome morphology and scant of chromosome markers. Here, we integrate the carrot linkage groups with pachytene chromosomes by fluorescent in situ hybridization (FISH) mapping genetically anchored bacterial artificial chromosomes (BACs). We isolated a satellite repeat from the centromeric regions of the carrot chromosomes, which facilitated the study of the pachytene-based karyotype and demonstrated that heterochromatic domains were mainly confined to the pericentromeric regions of each chromosome. Chromosome-specific BACs were used to: (1) physically locate genetically unanchored DNA sequences, (2) reveal relationships between genetic and physical distances, and (3) address chromosome evolution in Daucus. Most carrot BACs generated distinct FISH signals in 22-chromosome Daucus species, providing evidence for syntenic chromosome segments and rearrangements among them. These results provide a foundation for further cytogenetic characterization and chromosome evolution studies in Daucus.

AB The fungus Aspergillus flavus is responsible for producing carcinogenic mycotoxins, the aflatoxins, on corn (maize) and other crops. An additional harmful toxin, cyclopiazonic acid, is produced by some isolates of A. flavus. Several A. flavus strains that do not produce one or both of these mycotoxins are being used in biological control to competitively exclude the toxin-producing strains from the agroecosystem, particularly from seeds, grain and other marketable commodities. Three well-studied non-aflatoxigenic strains, including two that are commercially available, have been compared in side-by-side field trials. The results of that study, together with a growing understanding of A. flavus ecology and new genetic insights, are guiding the selection of biocontrol strains and influencing crop management decisions for safe and sustainable production.

AB Mycotoxins are secondary metabolites produced by certain filamentous fungi that can contaminate a large variety of agricultural commodities before and after harvest. Among different mycotoxins, aflatoxins and especially aflatoxin B1 are of particular concern because they are potent natural carcinogens. Aflatoxin-producing fungi, mainly Aspergillus flavus and A. parasiticus, are ubiquitous, being commonly isolated from agricultural soil and crop debris. Although many aspects of the ecology of aflatoxin-producing fungi have been elucidated, control of aflatoxin contamination of agricultural crops remains a difficult task. Agronomical practices promoting general plant health have shown variable and more frequently limited success in preharvest control of aflatoxin contamination. Competitive replacement of indigenous toxigenic soil isolates is considered a more promising and effective approach. This biocontrol strategy is based on field application of a large number of propagules of nontoxigenic strains of A. flavus. Biocontrol strains are typically formulated as inoculated or spore-coated grain seeds. More recently, efforts to explore new approaches and technologies have resulted in the development of other practical solutions, including a bioplastic-based formulation. This formulation originally developed in 2008, consists of bioplastic granules entrapping spores of the nontoxigenic biocontrol strain, A. flavus NRRL 30797. Laboratory and field studies that have been conducted until now have clearly shown that granules of the starch-based bioplastic Mater-Bi85%) agricultural, with major crops of corn and soybeans. Atrazine herbicide is of significant concern, as the St. Joseph River is the source of drinking water for the city of Fort Wayne, Indiana, with Cedar Creek being the main tributary. Major objectives were to evaluate the ability of AnnAGNPS to simulate runoff and atrazine concentrations in uncalibrated, calibrated, and validation modes. In an uncalibrated mode, flow discharge predictions by AnnAGNPS were satisfactory at the CCW scale but could be improved through calibration. Flow discharge for both CCW and MDS could be well matched with observed values during model calibration and validation. AnnAGNPS predictions of atrazine concentrations in runoff water were very poor, and it was impossible to improve the results through any type of calibration. Inspection of the model source code revealed a unit conversion error in the runoff value being input to the pesticide routine, which when corrected greatly improved the results. The corrected AnnAGNPS model code could be satisfactorily calibrated and validated for predictions of atrazine concentrations in the MDS, but not in the CCW where only coarse measured data were available.

AB Lake Eucha is a nexus of water quality conflicts between agribusiness and environmentalists, urban and rural stakeholders, and municipalities and state governments. The decline in water quality in Lake Eucha, a drinking water supply reservoir for the city of Tulsa, has been attributed to both municipal wastewater treatment plant effluent and the application of poultry litter as a fertilizer within the basin. Litigation has forced policy changes in the basin with little knowledge of their eventual impact on water quality. The Soil and Water Assessment Tool (SWAT) model was used to evaluate the effect of various nutrient management scenarios, including those forced by the litigation, on nutrient loads to Lake Eucha. The model was calibrated for streamflow and total phosphorus using a complex shuffled evolution approach on a 75 GHz computer cluster. These predictions were used to identify management strategies predicted to meet established in-lake water quality standards. SWAT predicted that the litigation-imposed changes in the basin have reduced potential phosphorus load to Lake Eucha by 39%. The model also predicted that additional changes will be needed to meet the current water quality standard. This study illustrates how a watershed model can be used to assess potential management scenarios and identify strategies to meet a particular water quality standard. This information allows policy makers to make more informed water quality management decisions.

AB Methods are needed for utilizing nutrients contained within animal wastewater lagoons. One potential method for capturing nutrients in a useful form is to grow vegetation on the lagoon. A study was conducted from 2005 to 2008 to determine the feasibility of growing vegetation on floating platforms on a single-stage swine wastewater lagoon. Five species were selected from earlier studies as having potential for growth on a commercial swine farm wastewater lagoon: common bermuda grass (Cynodon dactylon (L.) Pers.), Tifton 85 bermuda grass (Cynodon dactylon (L.) Pers.), St. Augustine grass (Stenotaphrum secundatum (Walter Kuntze)), fall panicum (Panicum dichotomiflorum (L.) Michx.), and giant reed (Arundo donax L.). The plants were periodically harvested as needed, and the biomass was weighed and analyzed for N, P, K, Ca, Mg, S, Al, B, Cd, Cr, Cu, Fe, Mn, Mo, Na, Ni, Pb, and Zn. Giant reed and St. Augustine grass were found to be unsuitable for long-term growth on the wastewater lagoon. The greatest biomass production (sum of six cuttings) was 3.6 kg m(-2) dry matter from Tifton 85 bermuda grass, followed by common bermuda grass (3.2 kg m(-2) dry matter) and fall panicum (3.1 kg m(-2) dry matter). All of the plant species accumulated greater than 1000 ppm Na. Nutrient (N, P, and K) uptake and removal from the wastewater with biomass harvesting was primarily a function of biomass produced. The greatest annual uptake and removal of N and P from the wastewater was by Tifton 85 bermuda grass in 2006, where three cuttings of the floating vegetation removed totals of 69 and 25 g m-2 N and P, respectively. Annual uptake and removal of K was greatest by fall panicum, where uptake and removal by three cuttings in 2007 totaled 78 g m-2. In 2008, weeds that had populated the mats were harvested for biomass and elemental uptake. Uptake and total removal of nutrients in two cuttings of the weeds in 2008 was lower than what was observed with the planted species. Total uptake and removal of N, P, and K by the weeds in 2008 was approximately 30, 10, and 30 g m(-2). The study showed that plant species exist that can grow and thrive on single-stage anaerobic wastewater lagoons on floating platforms for at least two years while taking up N, P, and K from the wastewater. Harvesting of biomass (which could potentially be used as a soil amendment or as cellulosic feedstock for bioenergy) from floating mats hence could be a mechanism for animal producers to both remove and productively use nutrients contained in the wastewater.

AB The effectiveness of a narrow grass hedge in reducing runoff nutrient loads following manure application was examined in this study. Beef cattle manure was applied to 0.75 m wide by 4.0 m long plots established on an Aksarben silty clay loam located in southeast Nebraska. Manure was added at rates required to meet none or the 1, 2, or 4 year nitrogen requirements for corn. Runoff water quality was measured during three 30 mm simulated rainfall events. Manure application rate significantly affected dissolved phosphorus (DP) and total phosphorus (TP) loads in runoff on the plots without a grass hedge. Howevet; DP and TP loads were not significantly affected by manure application rate on the plots containing a hedge. The hedge reduced the mean load of DP in runoff from 0.69 to 0.08 kg ha(-1) and the load of TP from 1.05 to 0.13 kg ha(-1). When averaged across manure application rates, 0.11 kg NO(3)-N ha(-1), 0.02 kg NH(4)-N ha(-1), and 0.49 kg total nitrogen (TN) ha(-1) were measured from the plots with a hedge, compared to 0.39 kg NO(3)-N ha(-1), 0.55 kg NH(4)-N ha(-1), and 2.52 kg TN ha(-1) front the plots without a hedge. For the plots with a grass hedge, runoff loads of DP and TP where manure was applied were similar to values obtained with no manure application. Each of the runoff water quality parameters was significantly affected by runoff rate. A narrow grass hedge placed on the contour across a hillslope significantly reduced runoff nutrient loads following variable manure applications.

AB Winter application of manure is commonly practiced in the northeastern and north-central U.S. Potential nutrient losses from winter-applied manure are difficult to predict due to uncertainty in weather forecasting and limited knowledge on soil-nutrient-hydrology interactions during the winter. The objective of this study was to extend the understanding of nutrient cycling and transport processes associated with manure application methods during winter months. Specifically, the influence of manure position within the snowpack on nutrient losses was examined using a laboratory approach. Dairy manure was applied either before, midway through, or upon completion of an artificial snowfall. Runoff and leachate were subsequently collected throughout a snowmelt event and rainfall simulations. Manure application prior to the snowfall increased the losses of total N and NH(4)-N in snowmelt runoff and resulted in larger losses of both N and P in runoff during the rainfall simulation. Manure application on top of the snow reduced the amount of NH(4)-N losses but increased the losses of organic N, DRP, and total P in snowmelt runoff The results of this research show that the relative position of manure within the snowpack plays a significant role in the fate of N and P from winter-applied manure.

AB Soil loss rates on rangelands are considered one of the few quantitative indicators for assessing rangeland health and conservation practice effectiveness. An erosion model to predict soil loss specific for rangeland applications is needed because existing erosion models were developed from croplands where the hydrologic and erosion processes are different, largely due to much higher levels of heterogeneity in soil and plant properties at the plot scale and the consolidated nature of the soils. The Rangeland Hydrology and Erosion Model (RHEM) was designed to fill that need. RHEM is an event-based derivation of the WEPP model made by removing relationships developed specifically for croplands and incorporating new equations derived from rangeland data. RHEM represents erosion processes under disturbed and undisturbed rangeland conditions, it adopts a new splash erosion and thin sheet-flow transport equation developed from rangeland data, and it links the model hydrologic and erosion parameters with rangeland plant communities by providing a new system of parameter estimation equations based on 204 plots at 49 rangeland sites distributed across 15 western U.S. states. RHEM estimates runoff erosion, and sediment delivery rates and volumes at the spatial scale of the hillslope and the temporal scale of a single rainfall event. Experiments were conducted to generate independent data for model evaluation, and the coefficients of determination (r(2)) for runoff and erosion predictions were 0.87 and 0.50, respectively, which indicates the ability of RHEM to provide reasonable runoff and soil loss prediction capabilities for rangeland management and research needs.

AB The first comprehensive life-cycle assessment (LCA) for soybean biodiesel produced in the U.S. was completed by the National Renewable Energy Laboratory (NREL) in 1998, and the energy inventory for this analysis was updated in 2009 using 2002 data. The continual adoption of new technologies in farming, soybean processing, and for biodiesel conversion affects the life-cycle energy use over time, requiring that LCA practitioners update their models as often as possible. This study uses the most recently available data to update the energy life-cycle of soybean biodiesel and makes comparisons with the two past studies. The updated analysis showed that the fossil energy ratio (FER) of soybean biodiesel was 5.54 using 2006 agricultural data. This is a major improvement over the FER of 3.2 reported in the 1998 NREL study that used 1990 agricultural data and significantly better than the FER of 4.56 reported using 2002 data. The improvements are primarily due to improved soybean yields and more energy-efficient soybean crushing and conversion facilities. The energy input in soybean agriculture was reduced by 52%, in soybean crushing by 58% and in transesterification by 33% per unit volume of biodiesel produced. Overall, the energy input reduction was 42% for the same amount of biodiesel produced. The addition of secondary inputs, such as farm machinery and building materials, did not have a significant effect on the FER. The FER of soybean biodiesel is likely to continue to improve over time because of increases in soybean yields and the development of increasingly energy-efficient technologies.

AB Contamination of grain products by fungus can lead to economic losses and is deleterious to human and livestock health. Detection and quantification of fungus-infected corn kernels would be advantageous for producers and breeders in evaluating quality and in selecting hybrids with resistance to infection. This study evaluated the performance of single-kernel near-infrared reflectance spectroscopy (NIRS) and color imaging to discriminate corn kernels infected by eight fungus species at different levels of infection. Discrimination was done according to the level of infection and the mold species. NIR spectra (904 to 1685 nm) and color images were used to develop linear and nonlinear prediction models using linear discriminant analysis (LDA) and multi-layer perceptron (MLP) neural networks. NIRS was able to accurately detect 98% of the uninfected control kernels, compared to about 89% for the color imaging. Results for detecting all levels of infection using NIR were 89% and 79% for the uninfected control and infected kernels, respectively; color imaging was able to discriminate 75% of both the control and infected kernels. In general, there was better discrimination for control kernels than for infected kernels, and certain mold species had better classification accuracy than others when using NIR. The vision system was not able to classify mold species well. The use of principal component analysis on image data did not improve the classification results, while LDA performed almost as well as MLP models. LDA and mean centering NIR spectra gave better classification models. Compared to the results of NIR spectrometry, the classification accuracy of the color imaging system was less attractive, although the instrument has a lower cost and a higher throughput.

AB We examined the effects of the introduced gypsy moth (Lymantria dispar) on seven species of North American woodpeckers by matching spatially explicit data on gypsy moth outbreaks with data on breeding and wintering populations. In general, we detected modest effects during outbreaks: during the breeding season one species, the Red-headed Woodpecker (Melanerpes erythrocephalus), increased over pre-outbreak levels, while during the winter one species, the Yellow-bellied Sapsucker (Sphyrapicus varius), increased and one, the Downy Woodpecker (Picoides pubescens), decreased from pre-outbreak levels. Responses following outbreaks were similarly variable, and in general we were unsuccessful at predicting population responses to outbreaks from a priori knowledge of woodpecker ecology and behavior. We did, however, find evidence that the response of at least half of the species changed over the 34-year period covered by the study: except for the Northern Flicker (Colaptes auratus), whose response to outbreaks during the winter decreased, populations generally responded more positively to outbreaks with time. This temporal response suggests that North American woodpeckers may be taking greater advantage of the resource pulse and/or habitat changes caused by outbreaks of this exotic pest now than previously, so in the future the effects of gypsy moth outbreaks on these species may increase.

AB A diversity array technology (DArT) marker platform was developed for the cotton genome, to evaluate the use of DArT markers compared with AFLP markers in mapping and transferability across the mapping populations. We used a reference genetic map of tetraploid Gossypium L. that already contained similar to 5000 loci, which coalesced into 26 chromosomes, to anchor newly developed DArT and AFLP markers with the aim of further improving utility and map resolution. Our results indicated that the percentage of polymorphic DArT markers that could be genetically mapped (78.15%) was much higher than that of AFLP markers (22.28%). Sequence analysis of DArT markers indicated that a majority matched known expressed sequence tag (EST) sequences from tetraploid and diploid Gossypium species. A total of 794 Arabidopsis genes were homologous with various DArT marker sequences. Chromosomes 5(A), 7(A), 19(D), 23(D), and 24(D) had more Arabidopsis syntenic DArT markers than the other chromosomes. Anchoring DArT markers from the reference map to a recombinant inbred line (RIL) map indicated that DArT markers will speed the building of maps in de novo RIL populations.

AB Simple sequence repeats (SSRs) or microsatellites are very useful molecular markers, owing to their locus-specific codominant and multiallelic nature, high abundance in the genome, and high rates of transferability across species. The soybean aphid (Aphis glycines Matsumura) has become the most damaging insect pest of soybean (Glycine max (L.) Merr.) in North America, since it was first found in the Midwest of the United States in 2000. Biotypes of the soybean aphid capable of colonizing newly developed aphid-resistant soybean cultivars have been recently discovered. Genetic resources, including molecular markers, to study soybean aphids are severely lacking. Recently developed next generation sequencing platforms offer opportunities for high-throughput and inexpensive genome sequencing and rapid marker development. The objectives of this study were (i) to develop and characterize genomic SSR markers from soybean aphid genomic sequences generated by next generation sequencing technology and (ii) to evaluate the utility of the SSRs for genetic diversity or relationship analyses. In total 128 SSR primer pairs were designed from sequences generated by Illumina GAII from a reduced representation library of A. glycines. Nearly 94% (120) of the primer pairs amplified SSR alleles of expected size and 24 SSR loci were polymorphic among three aphid samples from three populations. The polymorphic SSRs were successfully used to differentiate among 24 soybean aphids from Ohio and South Dakota. Sequencing of PCR products of two SSR markers from four aphid samples revealed that the allelic polymorphism was due to variation in the SSR repeats among the aphids. These markers should be particularly useful for genetic differentiation among aphids collected from soybean fields at different localities and regions. These SSR markers provide the soybean aphid research community with the first set of PCR-based codominant markers developed from the genomic sequences of A. glycines.

AB The Bacteriological Analytical Manual (BAM) Salmonella pre-enrichment broth [lactose (LAC) broth], buffered peptone water, and universal pre-enrichment (UP) broth were compared with TA10 broth, developed in our laboratory, for recovery of heat- and freeze-injured Salmonella (55 degrees C for 2-20 min and -20 degrees C for 2 months, respectively) from beef. Beef samples were contaminated with single Salmonella serovars, and contamination levels of 0.44 to <0.001 most probable number (MPN)/g and 0.74 to 0.14 MPN/g were used for heat- and freezing-induced injury studies, respectively. Twenty test portions (25 g) of the contaminated beef were pre-enriched in each broth, and the BAM Salmonella culture method was used thereafter. There was a significant difference (chi(2) = 7.73) in recovery of heat-injured Salmonella between TA10 broth and LAC broth, 189 (67.5%) versus 156 (55.7%) positive samples, respectively, determined by plating onto selective agars and identification by biochemical tests. For the recovery of freeze-injured Salmonella, there was a significant difference (chi(2) = 24.7) between TA10 and LAC broth, 189 (72.7%) versus 133(51.2%) positive samples, respectively. TA10 broth was more effective than LAC broth and UP broth for recovery of freeze-injured Salmonella. The results indicate that TA10 broth should be used instead of LAC broth for testing of beef that may be contaminated with heat- and freeze-injured Salmonella spp.

AB Many hydrologic models have been developed to help manage natural resources all over the world. Nevertheless, most models have presented a high complexity regarding data base requirements, as well as, many calibration parameters. This has brought serious difficulties for applying them in watersheds where there is scarcity of data. The development of the Lavras Simulation of Hydrology (LASH) in a GIS framework is described in this study, which focuses on its main components, parameters, and capabilities. Coupled with LASH, sensitivity analysis, parameter range reduction, and uncertainty analysis were performed prior to the calibration effort by using specific techniques (Morris method, Monte Carlo simulation and a Generalized Likelihood Uncertainty Estimation - GLUE) with a data base from a Brazilian Tropical Experimental Watershed (32 km(2)), in order to predict streamflow on a daily basis. LASH is a simple deterministic and spatially distributed model using long-term data sets, and a few maps to predict streamflow at a watershed outlet. We were able to identify the most sensitive parameters which are associated with the base flow and surface runoff components, using a reference watershed. Using a conservative threshold, two parameters had their range of values reduced, thus resulting in outputs closer to measured values and facilitating automatic calibration of the model with less required iterations. GLUE was found to be an efficient method to analyze uncertainties related to the prediction of mean daily streamflow in the watershed.

AB Soil water content is essential to understand the hydrological cycle. It controls the surface runoff generation, water infiltration, soil evaporation and plant transpiration. This work aims to analyze the spatial distribution of top soil water content and to characterize the spatial mean and standard deviation of top soil water content over time in an experimental catchment located in the Mantiqueira Range region, state of Minas Gerais, Brazil. Measurements of top soil water content were carried out every 15 days, between May/2007 and May/2008. Using time-domain reflectometry (TDR) equipment, 69 points were sampled in the top 0.2 m of the soil profile. Geostatistical procedures were applied in all steps of the study. First, the spatial continuity was evaluated, and the experimental semi-variogram was modeled. For the development of top soil water content maps over time a co-kriging procedure was used having the slope as a secondary variable. Rainfall regime controlled the top soil water content: during the wet season. Land use was also another fundamental local factor. The spatial standard deviation had low values under dry conditions, and high values under wet conditions. Thus, more variability occurs under wet conditions.

AB Movements by stream fishes have long been the subject of study and controversy. Although much discussion has focused on what proportion of fish adopt mobility within particular life stages, a larger issue involves the lifetime movements of individuals. I evaluated movements of different sizes and ages of Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus) using a variety of sampling methods from 1996 to 2001 in a 40 km network of main-stem and tributary segments of the North Fork Little Snake River, Wyoming, USA. The probability of movement was related to the period of observation, initial location, and possibly individual growth rate, whereas distance moved was related to fish size and initial location. Furthermore, it appeared that movements by juveniles were mostly downstream, whereas those of older fish were largely upstream. Movement of cutthroat trout in this basin appeared to be driven by ontogenetic changes in habitat use and variation in habitat productivity. Given that this stream network exemplifies the complexity typical of many mountain watersheds, movement as a life history tactic in fishes may be more common than is sometimes recognized.

AB Nursery irrigation regimes that recharged container capacity when target volumetric water content reached 72%, 58%, and 44% (by volume) influenced Pinus ponderosa Douglas ex Lawson & C. Lawson growth more than either a 1: 1 (by volume) Sphagnum peat - vermiculite (PV) or a 7: 3 (by volume) Sphagnum peat - sawdust (PS) medium. Exponential fertilization avoided confounding irrigation and fertilization. Temporary nitrogen (N) immobilization in PS caused transient allometric differences prior to hardening. Subsequent release of immobilized N during the onset of hardening, when daily N flux decreased from 4.2% to 1.6%, allowed PS seedlings to avoid foliar N dilution experienced by PV seedlings. Media yielded seedlings with similar final morphological characteristics, although PS seedlings had improved N status. At onset, particle density and volumetric water content were similar for both media, but PS held about 10% more water than PV at all water potentials at experiment conclusion. Exposure to the driest water content (44%) decreased seedling growth and root N status compared with cohorts that were provided ample moisture (72%). Despite maximum tissue heterogeneity within samples and regardless of irrigation regime, seedlings became 1.3% more depleted of C-13 as the growing season progressed. Refinement of sampling procedures, with focus on ontogenetics, may improve subsequent use of stable carbon isotopes in nursery research.

AB Predictive models of microclimate under various site conditions in forested headwater stream - riparian areas are poorly developed, and sampling designs for characterizing underlying riparian microclimate gradients are sparse. We used riparian microclimate data collected at eight headwater streams in the Oregon Coast Range to compare ordinary kriging (OK), universal kriging (UK), and kriging with external drift (KED) for point prediction of mean maximum air temperature (T-air). Several topographic and forest structure characteristics were considered as site-specific parameters. Height above stream and distance to stream were the most important covariates in the KED models, which outperformed OK and UK in terms of root mean square error. Sample patterns were optimized based on the kriging variance and the weighted means of shortest distance criterion using the simulated annealing algorithm. The optimized sample patterns outperformed systematic sample patterns in terms of mean kriging variance mainly for small sample sizes. These findings suggest methods for increasing efficiency of microclimate monitoring in riparian areas.

AB We used the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS) to simulate fuel treatment effects on 45 162 stands in low-to midelevation dry forests (e. g., ponderosa pine (Pinus ponderosa Dougl. ex. P. & C. Laws.) and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) of the western United States. We evaluated treatment effects on predicted post-treatment fire behavior (fire type) and fire hazard (torching index). FFE-FVS predicts that thinning and surface fuel treatments reduced crown fire behavior relative to no treatment; a large proportion of stands were predicted to transition from active crown fire pre-treatment to surface fire post-treatment. Intense thinning treatments (125 and 250 residual trees.ha(-1)) were predicted to be more effective than light thinning treatments (500 and 750 residual trees.ha(-1)). Prescribed fire was predicted to be the most effective surface fuel treatment, whereas FFE-FVS predicted no difference between no surface fuel treatment and extraction of fuels. This inability to discriminate the effects of certain fuel treatments illuminates the consequence of a documented limitation in how FFE-FVS incorporates fuel models and we suggest improvements. The concurrence of results from modeling and empirical studies provides quantitative support for "fire-safe" principles of forest fuel reduction (sensu Agee and Skinner 2005. For. Ecol.

ID FOREST INVENTORY; UNITED-STATES
AB Post-stratification is used to reduce the variance of estimates of the mean. Because the stratification is not fixed in advance, within-strata sample sizes can be quite small. The survey statistics literature provides some guidance on minimum within-strata sample sizes; however, the recommendations and justifications are inconsistent and apply broadly for many different population structures. The impacts of minimum within-strata and total sample sizes on estimates of means and standard errors were examined for two forest inventory variables: proportion forestland and cubic net volume. Estimates of the means seem unbiased across a range of minimum within-strata sample sizes. A ratio that described the decrease in variability with increasing sample size allowed for assessment of minimum within-strata sample requirements to obtain stable estimates of means. This metric indicated that the minimum within-strata sample size should be at least 10. Estimates of standard errors were found to be biased at small total sample sizes. To obtain a bias of less than 3%, the required minimum total sample size was 25 for proportion forestland and 75 for cubic net volume. The results presented allow analysts to determine within-stratum and total sample size requirements corresponding to their criteria for acceptable levels of bias and variability.

ID STEAM JET COOKING; DISPERSIONS; COMPLEXES
AB Many applications have been developed for aqueous dispersions of jet-cooked starch-oil composites prepared by excess steam jet cooking. Previous formulations have typically contained 20-50% oil by weight based on the weight of starch. To expand the range of potential applications, new preparation methods were investigated to increase the oil content to as high as four times the weight of starch. High-amylose corn starch was cooked in an excess-steam jet cooker in the presence of oleic acid, and soybean oil was added to form the starch-oil composites. Amylose is removed from solution by forming helical inclusion complexes with the oleic acid and, if the materials are cooled sufficiently quickly, the helical inclusion complexes only form small aggregates and shells around the oil droplets. Depending on the composition and preparation method, a wide range of stable, high-oil materials from low-viscosity liquids to smooth pastes can be formed. The flow, textural, and structural properties of these materials are shown. The materials can be used in a wide range of applications, including spray lubricants, lotions, and for fat delivery in cake mixes.

AB An extremely sensitive method for the analysis of 2-acetyl-1-pyrroline (2AP) in rice, employing stir bar sorptive extraction (Twister) was studied. The Twister stir bar is placed in the headspace of a 20-mL vial containing 1 g of rice kernels, 7.5 mL of 0.1M KOH, and 2.2 g of NaCl, along with a second Teflon-coated stir bar for mixing. Analytes are adsorbed onto the Twister for 4 hr at 40 degrees C and then desorbed at 270 degrees C into a GC column while cryofocusing at -80 degrees C. The headspace sorptive extraction (HSSE) method was able to detect <0.1 ppb of 2AP in rice. The precision of the HSSE method (>10%) was not as good as the GC/FID method (approximate to 6%). Using HSSE, 2AP was observed in all samples generally considered to be aromatic and was not observed in any nonaromatic samples. Additionally, a modified method for the synthesis of 2-acetyl-1-pyrroline was studied and the presence of a tautomer of 2-acetyl-1-pyrroline was confirmed.

AB The objective was to study the influence of jet-cooked Prowashonupana barley flour on total phenolic contents, antioxidant activities, water-holding capacities, and viscoelastic properties. Barley flour was jet-cooked without or with pH adjustment at 7, 9, or 11. Generally, the free phenolic content and antioxidant activity decreased after jet-cooking, while the bound phenolic content and antioxidant significantly increased regardless of pH. Detectable levels of gallic acid, caffeic acid, ferulic acid, and p-coumaroyl-pentose in the jet-cooked barley flour hydrolysates along with vitexin were found among 21 phenolics by LC-ESI-Q-TOF-MS analysis. Jet-cooking at an elevated pH resulted in increased pasting viscosities. The oil content was decreased after jet-cooking and continued to decrease with increased pH values. Jet cooking dramatically increased water holding capacity from 179% for unprocessed flour to 643% for jet-cooked flour without pH adjustment, and water-holding capacity was greatly increased to 914% by jet-cooking at pH 11. The combination of jet-cooking and pH adjustment had tremendous influence on water-holding and pasting properties. This increase in functionality should contribute to food applications such as bakery and frozen products because of the release of the bound phenolic content, antioxidant activities, and improved water-holding and pasting abilities.

TI Germ-Derived FAN as Nitrogen Source for Corn Endosperm Fermentation
SO CEREAL CHEMISTRY
LA English
DT Article
ID AMINO NITROGEN; PROTEASE; STARCH
AB Corn endosperm separated by dry fractionation could exhibit poor fermentation performance due to loss of germ components beneficial for yeast growth. Inorganic nitrogen and other nutritional supplementations are used to overcome slow fermentation rates. We investigated the use of a protease in generating free amino nitrogen (FAN) from germ as an alternative to exogenous nitrogen sources. Up to 300% more FAN can be generated from germ in 6 hr of incubation with protease than without protease. Protease incubation also resulted in higher dry solids (ds) and total glucose contents in the germ hydrolyzates. During fermentation without urea addition, ethanol yields were dependent on mash FAN concentrations. Ethanol yields increased to a maximum when FAN level was 80-90 mg of FAN/100 g ds. At half the optimal FAN level (approximate to 40 mg of FAN/100 g ds), nitrogen limitation occurred, as indicated by high residual glucose concentrations. However. germ FAN did not increase the ethanol yields compared to urea supplementation, likely because germ FAN resulted in lower substrate consumption compared to urea supplementation. Lower substrate consumption correlated to the increase in residual maltose with increase in initial FAN. Ethanol productivity in 0-24 hr of fermentation was higher with germ FAN than with urea, thus decreasing overall fermentation time.

AB Toxoplasma gondii is a widespread parasite of animals that causes zoonotic infections in humans. Previous studies have revealed a strongly clonal population structure in North America and Europe, while strains from South America are genetically separate and more diverse. However, the composition within North America has been questioned by recent descriptions of genetically more variable strains from this region. Here, we examined an expanded set of isolates using sequenced-based phylogenetic and population analyses to re-evaluate the population structure of T. gondii in North America. Our findings reveal that isolates previously defined by atypical restriction fragment length polymorphism patterns fall into two discrete groups. In one case, these new isolates represent variants of an existing lineage, from which they differ only by minor mutational drift. However, in the second case, it is evident that these isolates define a completely new lineage that is common in North America. Support for this new lineage was based on phylogeny, principle components analysis, STRUCTURE analyses, and statistical analysis of gene flow between groups. This new group, referred to as haplogroup 12, contains divergent genotypes previously referred to as A and X, isolated from sea otters. Consistent with this, group 12 was found primarily in wild animals, as well as occasionally in humans. This new lineage also has a highly clonal population structure. Analysis of the inheritance of multilocus genotypes revealed that different strains within group 12 are the products of a single recombination event between type 2 and a unique parental lineage. Collectively, the archetypal type 2 has been associated with clonal expansion of a small number of lineages in the North. as a consequence of separate but infrequent genetic crosses with several different parental lines.

ID TRITERPENOID SAPONINS; FUSARIC ACID; PLANT; QUANTIFICATION; TOXICITY
AB A variety of glycosylated and unglycosylated saponins from seven different plant families (Aquifoliaceae, Asparagaceae, Caryophyllaceae, Dioscoreaceae, Leguminosae, Rosaceae, Sapindaceae) were tested against the corn earworm, Helicoverpa zea, and the fall armyworm, Spodoptera frugiperda. The corn earworm feeds readily on both monocots and dicots, while the fall armyworm is primarily a grass feeder. Most of the saponins were similarly effective or ineffective against both insect species, with the glycosides being the primary active form (compared to aglycones). However, one aglycone possessed antifeedant properties toward the fall armyworm. Thus, in contrast to many plant secondary metabolites effective against either of these two species where the aglycone is more effective, in the case of the saponins the opposite is generally true. This appears to be a contradictory strategy of plant defenses that requires further consideration. The activity of protodioscin against insects is reported for the first time and may be important in insect defense by the bioenergy crop switchgrass.

AB Trimedlure is the most effective male-targeted lure for the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). A similar response is elicited by plant substances that contain alpha-copaene, a naturally-occurring sesquiterpene. alpha-Copaene is a complex, highly-volatile, widely-distributed plant compound, and male C. capitata respond to material from both hosts (e.g., Litchi chinensis) and non-hosts (e.g., Ficus benjamina) that contain alpha-copaene. Avocado, Persea americana, recently was found to contain varying amounts of alpha-copaene in the bark and underlying cambial tissue. Short-range attraction bioassays and electroantennography (EAG) were used to quantify responses of sterile male C. capitata to samples of rasped wood from four avocado genotypes, L. chinensis, and F. benjamina. Gas chromatography-mass spectral (GC-MS) analysis was used to identify and quantify the major sesquiterpenes. Attraction and EAG amplitude were correlated, with L. chinensis eliciting the highest and F. benjamina the lowest responses. Responses to the avocado genotypes were intermediate, but varied among the four types. GC-MS identified 13 sesquiterpenes, including alpha-copaene, from all samples. Amounts of alpha-copaene in volatile collections from samples (3 g) ranged from 11.8 mu g in L. chinensis to 0.09 mu g in F. benjamina, which correlated with short-range attraction and EAG response. alpha-Copaene ranged from 8.0 to 0.8 mu g in the avocado genotypes, but attraction and EAG responses were not correlated with the amount of alpha-copaene. Differences in enantiomeric structure of the alpha-copaene in the different genotypes and/or presence of additional sesquiterpenes may be responsible for the variation in male response. EAG responses were correlated with the amount of several other sesquiterpenes including alpha-humulene, and this compound elicited a strong antennal response when tested alone.

AB Intraspecific attraction depends both on the cues provided by the attracting individual and the response of the attracted individual. These attracting cues are related not only to current conditions, but also are a reflection of individual and population life history. These relationships were examined by placing red flour beetle, Tribolium castaneum (Herbst.), adults in flasks at increasing densities and monitoring the changes in volatile chemical emission over time. Only certain chemicals were quantified: methyl benzoquinone, ethyl benzoquinone and 4,8-dimethyldecanal, all of which are known to impact the biology of T. castaneum. The flasks were used as sources for both quantification of the chemicals and for bioassays. Additional bioassays were conducted with synthetic 4,8-dimethyldecanal, a known aggregation pheromone component, to evaluate attraction with respect to population density. Tribolium castaneum density affected both the release of volatile chemicals and the responses of conspecifics to those chemicals. The results indicated that while there were important effects of beetle density on chemical emission and response, none of the chemicals evaluated emerged as promising synergists to the current aggregation pheromone 4,8-dimethyldecanal. The benzoquinones released in response to stress and density acted as anti-aggregation pheromones along with their accepted defensive function.

AB The use of radioactive tracers for environmental fate and transport studies of emerging contaminants, especially for those that are labile, offers convenience in tracking study compounds and their metabolites, and in calculating mass balances. The aim of this study was to synthesize radiolabeled glucuronide and sulfate conjugates of 17 beta-estradiol (17 beta-E2). The conjugates 17 beta-[4-(14)C] estradiol-3-glucuronide ([(14)C]17 beta-E2-3-G) and 17 beta-[4-(14)C] estradiol-17-sulfate ([(14)C]17 beta-E2-17-S) were synthesized utilizing immobilized enzyme and chemical syntheses, respectively. Microsomal proteins from the liver of a phenobarbital induced pig ( Sus scrofa domestica) were harvested and used to glucuronidate [(14)C]17 beta-E2. Synthesis of [(14)C]17 beta-E2-17-S consisted of a three-step chemical process - introducing a blocking group at the C-3 position of [(14)C]17 beta-E2, sulfation at C-17 position, and subsequent deblocking to yield the desired synthetic product. Successful syntheses of [(14)C]17 beta-E2-3-G and [(14)C]17 beta-E2-17-S were achieved as verified by liquid chromatography, radiochemical analyses, quadrupole-time-of-flight (QTOF) mass spectrometry, and (1)H and (13)C nuclear magnetic resonance spectroscopy. Radiochemical yields of 84 and 44% were achieved for 17 beta-E2-3-G and 17 beta-E2-17-S, respectively. Synthetic products were purified using high-performance liquid chromatography and radiochemical purities of 98% or greater were obtained.

AB There is an emerging recognition that natural lands and their conservation are important elements of a sustainable drinking water infrastructure. We conducted a national, watershed-level environmental assessment of 5,265 drinking water watersheds using data on land cover, hydrography and conservation status. Approximately 78% of the conterminous United States lies within a drinking water watershed. The typical drinking water watershed had a high percentage of natural vegetation ((x) over tilde = 77%) but a low percentage of it was set aside for conservation ((x) over tilde = 3%). Median percentage values for urban and agriculture were 5 and 8%, respectively. Between ca. 1992 and ca. 2001, approximately 23% of the drinking water watersheds lost at least 1% of their natural vegetation, and approximately 9% of the watersheds had at least a 1% increase in the amount of urban land. Loss of natural vegetation was common in nearly all areas of the country, but also concentrated in the Ohio River and Southeast hydrologic regions. Urbanization was concentrated in the eastern United States, primarily in the Mid-Atlantic and Southeast hydrologic regions.

AB Thermal and hydrothermal biochars were characterized, and adsorption of bisphenol A (BPA), 17 alpha-ethinyl estradiol (EE2) and phenanthrene (Phen) was determined to investigate the sorption characteristic difference between the two types of biochars. Thermal biochars were composed mostly of aromatic moieties, with low H/C and O/C ratios as compared to hydrothermal ones having diverse functional groups. Single-point organic carbon-normalized distribution coefficients (logK(OC)) of EE2 and BPA of hydrothermal biochars were higher than thermal biochars, while Phen logK(OC) values were comparable among them. Xray diffraction and solid state nuclear magnetic resonance results suggested that hydrothermal biochars consisted of more amorphous aliphatic-C, possibly being responsible for their high sorption capacity of Phen. This study demonstrated that hydrothermal biochars could adsorb a wider spectrum of both polar and nonpolar organic contaminants than thermally produced biochars, suggesting that hydrothermal biochar derived from poultry and animal waste is a potential sorbent for agricultural and environmental applications.

AB Dicarboxylic organic acids have properties that differ from those of sulfuric acid during hydrolysis of lignocellulose. To investigate the effects of different acid catalysts on the hydrolysis and degradation of biomass compounds over a range of thermochemical pretreatments, maleic, oxalic and sulfuric acids were each used at the same combined severity factor (CSF) values during hydrolysis. Xylose and glucose concentrations in hydrolysates were highest with maleic acid. Oxalic acid gave the next highest followed by sulfuric acid. This ranking was particularly true at low CSF values. The concentrations of glucose and xylose increased with oxalic and sulfuric acid pretreatments as the CSF increased, but they never attained the levels observed with maleic acid. Among sulfuric, oxalic and maleic acid treatments, the amount of xylose released as xylooligosaccharide was highest with sulfuric acid. The fraction of xylooligosaccharide was lowest with the maleic acid and the oligosaccharide fraction with oxalic acid fell in between. Furfural and hydroxymethyl furfural levels were also highest with maleic acid. In subsequent fermentations with pretreated biomass, the ethanol concentration was maximal at 19.2 g/l at CSF 1.9 when maleic acid was used as the pretreatment catalyst. This corresponded to an ethanol volumetric production rate of 0.27 g ethanol/l per h. This was the same condition showing the highest xylose production in following pretreatment with various acid catalysts. These findings suggest that maleic and oxalic dicarboxylic acids degrade hemicelluloses more efficiently than does sulfuric acid. Published by Elsevier Ltd.

AB The mechanisms of stabilization by silicon-rich amendments of cadmium, zinc, copper and lead in a multi-metal contaminated acidic soil and the mitigation of metal accumulation in rice were investigated in this study. The results from a pot experiment indicated that the application of fly ash (20 and 40 g kg(-1)) and steel slag (3 and 6 g kg(-1)) increased soil pH from 4.0 to 5.0-6.4, decreased the phytoavail-ability of heavy metals by at least 60%, and further suppressed metal uptake by rice. Diffusion gradient in thin-film measurement showed the heavy metal diffusion fluxes from soil to solution decreased by greater than 84% after remediation. X-ray diffraction analysis indicated the mobile metals were mainly deposited as their silicates, phosphates and hydroxides in amended treatments. Moreover, it was found metal translocation from stem to leaf was dramatically restrained by adding amendments, which might be due to the increase of silicon concentration and co-precipitation with heavy metals in stem. Finally, a field experiment showed the trace element concentrations in polished rice treated with amendments complied with the food safety standards of China. These results demonstrated fly ash and steel slag could be effective in mitigating heavy metal accumulation in rice grown on multi-metal contaminated acidic soils. (C) 2011 Elsevier Ltd.

AB This study was carried out to develop and characterize mouse monoclonal antibodies (mAbs) against chicken CD80 (chCD80). A recombinant plasmid containing a chCD80/horse IgG4 fusion gene was constructed and expressed in CHO cells to produce recombinant cliCD80/IgG4 protein. Chicken CD80 was purified from the chCD80/IgG4 fusion protein following enterokinase digestion, and used to immunize BALB/c mice, resulting in 158 hybridomas that produced mAbs against chCD80. Three mAbs with high binding specificity for recombinant chCD80/IgG4-transfected CHO cells were identified by flow cytometry, and one of these (#112) was selected for further characterization. Immunoprecipitation of CD80/IgG4-CI-10 cell extract, or lipopolysaccharide (LPS)-treated monocytes identified 35.0 kDa proteins. Immunohistochemical analysis revealed chCD80-expressing cells exclusively in the bursal follicles at the outer portion of the cortex, and throughout the red pulp and the outer boundary of the white pulp in the spleen. By immunofluorescence microscopy, chCD80 was observed on intestinal dendritic cells. LPS treatment of bursa or spleen monocytes for 24 or 48 h increased chCD80 expression. Finally, addition of chCD80 mAb to Con A-stimulated spleen cells inhibited the expression of major histocompatibility complex class II antigens and IL-2-driven proliferation of lymphoblast cells. In summary, these chCD80 mAbs will serve as valuable immunological reagents for basic and applied poultry immunology research. Published by Elsevier Ltd.

AB Clomazone herbicide is registered for use in watermelon; however, crop tolerance is marginal, and the recommended use rates (0.17 to 0.28 kg a.i./ha) are lower for watermelon than for other crops. In a greenhouse germplasm evaluation experiment including 56 germplasm accessions and watermelon cultivars, three Citrullus lanatus var. citroides PI accessions (PI 482324, PI 5003540, and PI 532624) were not injured by clomazone, whereas most of the other accessions and cultivars were moderately or severely injured. A greenhouse concentration response experiment demonstrated that the clomazone concentration required to cause moderate injury to the tolerant 'PI 500354' was approximately three times the concentration required to cause similar injury to the susceptible citroides accession 'PI 244017', and the concentration required to cause 50% shoot biomass reduction was approximately five times greater for 'PI 500354' than for 'Charleston Gray' watermelon. Subsequent field experiments demonstrated that two tolerant accessions ('PI 500354' and 'PI 482324') were injured less initially by clomazone and recovered more rapidly from clomazone injury than two susceptible accessions ('PI 244017' and 'PI 271773') and two watermelon cultivars ('Charleston Gray' and 'Crimson Sweet'). Tolerant germplasm accessions like 'PI 482324' and 'PI 500354' may be useful as sources of clomazone tolerance in watermelon breeding. Chemical name used: clomazone {2-[(2-chlorophenyl)methyl]-4,4-dimethyl-3-isoxazolidinone}.

AB Prunella vulgaris (Lamiaceae), commonly known as selfheal, is a perennial herb with a long history of use in traditional medicine. Recent studies have found that P. vulgaris possesses anti-inflammatory, antiviral, and antibacterial properties, and it is likely that this will lead to increased commercial demand for this species. To date, research publications on P. vulgaris cultivation and genetics are scarce. Using accessions originally collected from different geographical regions, we investigated the breeding system of this species by observing variation in floral morphology, time of pollen release, and selfed-seed set in bagged flowers and isolated plants. Two types of floral morphology, one with exerted styles, extending past open corollas when viewed from above, and the other with shorter, inserted styles, were found among 30 accessions. Two accessions originally collected from Asia uniformly displayed exerted styles, and 27 accessions had inserted styles. One accession from Oregon displayed variation in this trait among individual plants. Microscopic observation of seven accessions, including ones with both exerted and inserted styles, revealed that they all release pollen to some degree before the flowers open. Using bagged flowers, we found that selfed-seed set varied widely among eight accessions, ranging from 6% to 94%. However, bagging may underestimate seed set for some accessions. The two accessions with the lowest rates when using bagged flowers increased in seed set by 350% and 158%, respectively, when we evaluated single, unbagged plants in isolation cages. The accession with 6% selfed-seed set when bagged also had exerted styles. These findings suggest that mating systems in P. vulgaris may be in the process of evolutionary change and that understanding breeding-system variation should be useful in developing efficient seed-regeneration protocols and breeding and selection strategies for this species.

Overall, during 2007 and 2008 growing seasons, total tomato yields (between 58,905 and 60,115 kg.ha(-1)) and marketable tomato yields (between 48,331 and 49,873 kg.ha(-1)) were significantly higher than in 2005 and 2006 (between 49,656 and 50,151 kg.ha(-1) and from 40,581 to 41,194 kg.ha(-1)) for total and marketable tomato yields, respectively. During the 2006 and 2008 growing seasons, plastic cover provided higher yield (60,921 and 73,718 kg.ha(-1)) compared with rye and crimson clover overall shank treatments. In 2007, higher yield was produced following rye without shank (70,577 kg.ha(-1)) compared with plastic mulch and crimson clover treatments. Across years, tomato yield after crimson clover was lower compared with rye and plastic. Percent of marketable fruit yield to total yield exceeded 80% in all treatments, including the plastic control. Cover crops and shank treatments did not affect percentage of marketable tomato yield compared with total tomato yield. Cover crops, especially rye, can provide an alternative in tomato production for those producers not wanting to use plastic mulches.

TI Field Survey and Fungicide Screening of Fungal Pathogens of Rambutan
(Nephelium lappaceum) Fruit Rot in Hawaii

AB Rambutan (Nephelium lappaceum Linn.) is a tropical fruit in Hawaii that has increased in value in the niche market of exotic fruits. The primary limitation to preharvest and postharvest quality is the occurrence of fungal diseases of the fruit. A survey of rambutan disease was conducted at orchards 9.7 km south and 29.0 km north of Hilo, HI, to determine the main fungal pathogens affecting preharvest fruit quality. Pericarp of rambutan fruit revealed brown to black lesions that progressed to blackening and drying of the fruit with some fruits becoming totally mummified. Four fungi consistently isolated from symptomatic fruit included Lasmenia, Pestalotiopsis, Phomopsis, and Colletotrichum spp. Over the 2-year sampling period, disease incidence from more than 300 fruits sampled was 84.6%. Nine rambutan cultivars were evaluated for disease incidence under field conditions. Disease incidence was greater than 90% for 'Sitangku' and 'R167' but less than 60% for 'Chompoo'. Twelve fungal isolates from infected fruit were selected for further characterization (six Lasmenia isolates and two isolates each of Pestalotiopsis, Phomopsis, and Colletotrichum). Morphology, colony characteristics, and pathogenicity of the isolates were examined. The optimum growth temperature for all fungal isolates ranged between 22 and 28 degrees C. Molecular methods were used to confirm the identity of the fungi. The fungal isolates were evaluated for in vitro baseline sensitivities for mycelial growth for fungicides registered for use in Hawaii (Abound (R) and Trilogy (R)). Abound was more effective at inhibiting fungal growth than was Trilogy (R); however, efficacy appeared to be influenced by fungal genera. Inhibition of fungal growth by Abound (R) ranged from a 76% reduction for Lasmenia to a 23% reduction for Phomopsis isolates.

AB Samples of vitamin D fortified orange juice obtained from retail food stores were analyzed for vitamin D(3) content using a method developed by combining the best features of two AOAC methods. Detection by ultraviolet absorption at 265 nm was compared to detection by selected ion monitoring (SIM) using atmospheric pressure chemical ionization (APCI) mass spectrometry (MS). Furthermore, an ion trap (IT) mass spectrometer was employed in a 'dual parallel MS' arrangement to simultaneously obtain qualitative APCI-ITMS data. The method was applied to 33 samples of 3 national American orange juice brands and 7 samples of 5 other American brands collected using a statistically designed sampling plan as part of the National Food and Nutrient Analysis Program to provide values for the USDA National Nutrient Databank for Standard Reference. Vitamin D(3) values ranged from 1.071 mu g/100 g (43 IU/100 g) to 1.663 mu g/100 g (67 IU/100 g), with an average across 55 samples analyzed, including duplicates, of 1.4 +/- 0.1 mu g/100 g (57 +/- 5 IU/100 g). The average of the 38 non-zero uniquely identified samples, using the averages of duplicate sets, was 1.4 +/- 0.1 mu g/100 g (57 +/- 5 IU/100 g), indicating that a typical 8 oz. (similar to 240 mL = 240 cm(3)) glass of orange juice provided 3.4 +/- 0.3 mu g (140 +/- 10 IU) vitamin D(3). Published by Elsevier Inc.

AB Skates (Raja rhina) have recently become a small commercial fishery in Alaska and along the western United States coast. Most of the skate byproduct is discarded or made into meal; therefore, there is opportunity to enhance the utilization for skate byproducts. The objective of this research project was to chemically characterize longnose skate livers. Livers from five long nose skates, caught off the coast of Kodiak, Alaska, were obtained immediately after the fins (called "wings") had been removed by a commercial processor. Each liver was subjected to the following analysis: proximate composition, minerals, amino acids, alpha-tocopherol, protein gel electrophoresis, fatty acid profiles, thiobarbituric acid reactive substances (TBARS) and biogenic amines (BA). Livers were composed of lipid (49.6%), moisture (41.0%), protein (10.9%) and ash (0.8%). High levels of alpha-tocopherol were found in the livers (142 mu g/g oil). Fatty acid profile indicated that the lipids extracted from livers contained high concentrations of eicosapentaenoic acid (16.0%) and docosahexaenoic acid (17.7%). Average TBARS values were low at 1.5 mu g malondialdehyde/g oil, indicating low levels of lipid oxidation. The lysine content as percent of total amino acids on a weight basis was 6.1% and methionine content was 2.8%. Analysis of BA found putrescine (31 mg/kg liver) and spermine (85 mg/kg liver) present. Preliminary results suggest long nose skate livers as an abundant source of n-3 fatty acids and amino acids. Published by Elsevier Inc.

AB Objective: To estimate the costs of satisfying MyPyramid fruit and vegetable guidelines, with a focus on whether low-income households can bear these costs.
Design: Descriptive analysis of the 2008 National Consumer Panel with information on the food purchases of 64,440 households across the contiguous United States was used to analyze the cost of fruits and vegetables. Costs per MyPyramid cup-equivalents were calculated by accounting for cooking yields and the portion of a food item's retail weight that is inedible.
Variables Measured: Costs per cup-equivalent for less expensive fruits and vegetables by MyPyramid subgroup including whole and cut fruit, fruit juice, dark green vegetables, orange vegetables, starchy vegetables, other vegetables, and legumes.
Results: In 2008, a variety of fruits and vegetables was available for an average cost of $0.40 to $0.50 per cup-equivalent. MyPyramid fruit and vegetable recommendations could be satisfied at this cost level.
Conclusions and Implications: Low-income Americans facing national average food prices can satisfy MyPyramid fruit and vegetable guidelines with a budget equal to the Thrifty Food Plan allocation to fruits and vegetables. However, many low-income households spend too much money on food that is low in fruit and vegetable content. Some money should be reallocated to fruits and vegetables.

TI Identification of Simple Sequence Repeat Markers that Differentiate
Bermudagrass Cultivars Derived from 'Tifgreen'
SO JOURNAL OF THE AMERICAN SOCIETY FOR HORTICULTURAL SCIENCE
LA English
DT Article
ID MICROSATELLITES; REGISTRATION
AB The release of the bermudagrass (Cynodon spp.) triploid hybrid 'Tifgreen' revolutionized southeastern U.S. golf course greens. Off-types within this cultivar began to be identified soon after the initial plantings, and through the last 50 years, many of the best performing off-types have been released as new cultivars. Examination of some of the most popular somatic mutants with a new set of 47 simple sequence repeat (SSR) markers and 23 previously discovered genomic SSR markers identified five polymorphic fragments (as compared with 'Tifgreen') among three cultivars, TifEagle, MiniVerde, and Tifdwarf. Each polymorphism appears to be a slight increase/decrease in microsatellite repeat number and the polymorphic fragments are unique for each cultivar. Two polymorphic fragments were identified that were unique to 'Tifdwarf', one polymorphic fragment was unique to 'TifEagle', and two polymorphic fragments were unique to 'MiniVerde'. Furthermore, three of the five polymorphic markers display an additional allele only in the shoot tissue but not in the root tissue of 'TifEagle' and 'Tifdwarf'. This finding suggests that 'TifEagle' and 'Tifdwarf' are somatic chimeras. This set of SSR markers identifies repeatable polymorphic fragments among multiple 'Tifgreen'-derived cultivars and gives insight into the nature of the mutations that exist within 'Tifgreen'.

AB Three tomato (Solanum lycopersicum) cultivars [Walter LA3465 (heat-tolerant), Edkawi LA 2711 (unknown heat tolerance, salt-tolerant), and LA1310 (cherry tomato)] were compared for changes in leaf proteomes after heat treatment. Seedlings with four fully expanded leaves were subjected to heat treatment of 39/25 degrees C at a 16:8 h light dark cycle for 7 days. Leaves were collected at 1200 FIR, 4 h after the light cycle started. For 'Walter' LA3465, heat-suppressed proteins were geranylgeranyl reductase, ferredoxin-NADP (+) reductase, Rubisco activase, transketolase, phosphoglycerate kinase precursor, fructose bisphosphate aldolase, glyoxisomal malate dehydrogenase, catalase, S-adenosyl-L-homocysteine hydrolase, and methionine synthase. Two enzymes were induced, cytosolic NADP-malic enzyme and superoxide dismutase. For 'Edkawi' LA2711, nine enzymes were suppressed: ferredoxin-NADP (+) reductase, Rubisco activase, S-adenosylmethionine synthetase, methioine synthase, glyoxisomal malate dehydrogenase, enolase, flavonol synthase, M1 family peptidase, and dihydrolipoamide dehydrogenase. Heat-induced proteins were cyclophilin, fructose-1,6-bisphosphate aldolase, transketolase, phosphoglycolate phosphatase, ATPase, photosystem 11 oxygen-evolving complex 23, and NAD-dependent epimerase/dehydratase. For cherry tomato LA 1310, heat-suppressed proteins were aminotransferase, S-adenosyl-L-homocysteine hydrolase, L-ascorbate peroxidase, lactoylglutathione lyase, and Rubisco activase. Heat-induced enzymes were glyoxisomal malate dehydrogenase, phosphoribulokinasee, and ATP synthase. This research resulted in the identification of proteins that were induced/repressed in all tomato cultivars evaluated (e.g., Rubisco activase, methionine synthase, adenosyl-L-homocysteine hydrolase, and others) and those differentially expressed (e.g., transketolase).

AB Salmonella enterica serovar Enteritidis (S. Enteritidis) is a major cause of food-borne gastroenteritis in humans worldwide. Poultry and poultry products are considered the major vehicles of transmission to humans. Using cell invasiveness as a surrogate marker for pathogenicity, we tested the invasiveness of 53 poultry-associated isolates of S. Enteritidis in a well-differentiated intestinal epithelial cell model (Caco-2). The method allowed classification of the isolates into low (n=7), medium (n=18) and high (n=30) invasiveness categories. Cell invasiveness of the isolates did not correlate with the presence of the virulence-associated gene spvB or the ability of the isolates to form biofilms. Testing of representative isolates with high and low invasiveness in a mouse model revealed that the former were more invasive in vivo and caused more and earlier mortalities, whereas the latter were significantly less invasive in vivo, causing few or no mortalities. Further characterization of representative isolates with low and high invasiveness showed that most of the isolates with low invasiveness had impaired motility and impaired secretion of either flagella-associated proteins (FlgK, FljB and FlgL) or type III secretion system (TTSS)-secreted proteins (SipA and SipD) encoded on Salmonella pathogenicity island-1. In addition, isolates with low invasiveness had impaired ability to invade and/or survive within chicken macrophages. These data suggest that not all isolates of S. Enteritidis recovered from poultry may be equally pathogenic, and that the pathogenicity of S. Enteritidis isolates is associated, in part, with both motility and secretion of TTSS effector proteins.

AB Livestock performance is a critical indicator of grassland production systems and is influenced strongly by precipitation and stocking rates. However, these relationships require further investigation in the arid Desert Steppe region of northeastern China. We employed a randomized complete block design with three replications and four grazing treatments (nongrazed exclosure [Control]), lightly grazed [LG], moderately grazed [MG], and heavily grazed [HG]) by sheep in a continuously grazed system (June to November), to test the effect of stocking rate on sheep performance. The planned stocking rates were 0, 0.15, 0.30, and 0.45 sheep . ha(-1) . mo(-1), for the control, LG, MG, and HG treatments, respectively. However, actual stocking rates were calculated for each paddock in each year based on a 50-kg sheep equivalent (SE). Annual net primary production (ANPP) was determined at peak standing crop in August 2004 to 2008. Live weight gain was determined for the summer and fall periods, as well as the total grazing period, in each year. ANPP decreased with increasing stocking rate, and daily live weight gain per head decreased linearly with increasing stocking rates over the total grazing period but in a quadratic manner over the summer period with a plateau at the lower rates. Maximum sheep production per unit area over the total grazing season occurred at about 2 SE ha(-1) for about a 5-mo grazing period, but individual gains per sheep were predicted to decline after about 1 SE ha(-1) presumably because of forage limitations. However, in order to achieve stable annual production, we recommend that the Desert Steppe be grazed at about 0.77 SE ha(-1) for a 5-mo period (0.15 SE ha(-1) . mo(-1)). This estimate is based on published grazing strategies that consider an average ANPP with a recommended utilization rate of 30%.

AB There is global recognition that sustainable land use requires monitoring that will detect change on a scale that protects the resource. That fundamental necessity is threatened where labor-intensive methods and high labor costs cause sampling deficiencies and increased Type-II error rates (false negatives). Ground-based imaging is a monitoring method that reduces monitoring labor costs. Nadir (vertical) images acquired with common digital cameras can be manually analyzed for cover using free software. We used an innovative field protocol to acquire standardized, freehand, nadir images (samples) of rangeland, then compared point intercept (PI) and image-analysis techniques. Between methods, precision (repeatability) across users was equivalent; cover measurements were often different, and the image-analysis technique took only a third as long to complete. Image analysis has several advantages over PI besides the reduced labor cost: Images are permanent resource records available for reanalysis if data are questioned, if software improves, or if management objectives change; and image analysis is less biased by moving vegetation, moving pointing devices, and bright vegetation color.

AB Techniques to monitor populations of feral swine (Sus scrofa) relative to damage control activities are needed on rangelands. Our objectives were to describe and assess a mark recapture technique using tetracycline hydrochloride (TH) for monitoring feral swine populations. We established bait stations at study sites in southern and central Texas. During 1 d, we replaced normal soured corn bait with bait containing TH and counted the number of feral swine that consumed bait with observers. We conducted feral swine removal using box-style traps and helicopters, at which time we collected teeth for TH analysis. In southern Texas, we estimated population reduction to be 43%. In central Texas, we estimated population reduction of 31%. Our mark recapture population monitoring technique would complement programs to manage feral swine populations and damage through lethal control.

AB Organic materials improve soil properties conducive to plant growth and may be necessary to stabilize lead (Pb) and zinc (Zn) mine wastes. Composted beef manure was applied to mine wastes at two sites at 45 and 269 Mg ha(-1) with and without lime and bentonite. Switchgrass (Panicum virgatum) was established as a vegetative cover. Compost significantly increased waste nutrient content, pH, and available water, and decreased heavy metal availability. The largest total phospholipid fatty acid (PLFA) increase was in the high compost treatment, with values of 80.3 and 30.2 (site A) and 84.9 and 23.1 (site B) mu mol kg(-1) soil for treated and control, respectively. However, high rates of compost (269 Mg ha(-1)) were generally required to increase bacterial and fungal communities beyond the control. The high compost-treated waste exhibited increased arylsulfatase, phosphatase, and beta-glucosidase enzyme activities. Observed increases in pH may have resulted in lowered enzyme activity in the low compost treatment. Results suggest that an organic matter addition above 45 and up to 269 Mg ha may be needed to support and sustain microbial activity and biomass in mine waste materials, at least over the two year period evaluated.

AB Changes in soil physical characteristics induced by soil compaction may alter soil microhabitats and, therefore, play a significant role in governing soil microorganisms and their activities. Laboratory incubation and field experiments (in 2001 and 2002) were conducted to investigate the effect of soil compaction on soil microbiological properties in a claypan soil amended with poultry litter and cropped to corn (Zea mays L.). In both laboratory and field studies, moderate soil compaction increased total soil organic C. beta-glucosidase activity, microbial biomass C (MBC), and microbial functional diversity, but decreased soluble organic C (Sol C). However, more severe soil compaction imposed in the laboratory caused an adverse effect on these soil microbiological properties, except for Sol C. Turkey (Meleagris gallopavo) litter application and cropping significantly increased soil beta-glucosidase activity, MBC, Sol C and microbial functional diversity, partly due to inputs of labile C substrates from both litter and crops. Overall, modification of soil microhabitat by compaction could change soil microbial growth and activity in relation to C and shift soil microbial functional diversity; however, the positive effects of litter addition and cropping could overcome the compaction effect on these soil microbiological properties.

AB The goal of this study was to evaluate the effectiveness of a public health educational campaign to reduce backyard mosquito-larval habitats. Three communities each, within two New Jersey counties, were randomly selected to receive: (1) both education and mosquito control, (2) education only, and (3) no education or mosquito control. Four separate educational events included a 5-day elementary school curriculum in the spring, and three door to door distributions of educational brochures. Before and after each educational event, the numbers of mosquito-larval container habitats were counted in 50 randomly selected homes per study area. Container surveys allowed us to measure source reduction behavior. Although we saw reductions in container habitats in sites receiving education, they were not significantly different from the control. Our results suggest that traditional passive means of public education, which were often considered the gold standard for mosquito control programs, are not sufficient to motivate residents to reduce backyard mosquito-larval habitats.

ID SUGARCANE
AB Different sources of plant stress, when present together, can have compounded effects on cane growth and yield. The objectives of this experiment were to determine: 1) if late-season (Nov. 1) glyphosate ripener application increases sucrose yield in the four common commercial sugarcane cultivars grown in Louisiana, USA 2) cultivar differences in susceptibility to injury from residual glyphosate in successive ratoon crops, and 3) if the stress of residual glyphosate on the subsequent ratoon crop is compounded by the presence of post-harvest residue. Glyphosate was applied on Nov. 1 (0.21 kg ai ha(-1)) to the first-ratoon crop. Two weeks after the first ratoon was harvested, the blanket of crop residue was either allowed to remain or completely removed by burning. Regardless of variety, late-season ripener application offered no increase in sucrose yield in first ratoon, and residual effects of glyphosate in the subsequent second-ratoon crop yield were not variety specific. Residual effect of glyphosate when post-harvest residue was not removed reduced sucrose yields by 13% relative to the non-treated control. Sucrose yield in the second-ratoon crop was not reduced when glyphosate was applied and residue was removed. When treated with glyphosate the previous year, residue retention reduced stalk population and photosynthesis in the second-ratoon crop compared to when residue was removed. Late-season glyphosate ripener applications are not recommended due to a lack of response by sugarcane coupled with the potential of residual injury effects caused by translocation of glyphosate into the crown, especially if post-harvest residue cannot be removed prior to the emergence of the subsequent ratoon crop.

AB In order to understand the role of cytosolic antioxidant enzymes in drought stress protection, transgenic tobacco (Nicotiana tabacum cv. Xanthi) plants overexpressing cytosolic Cu/Zn-superoxide dismutase (cytsod) (EC 1.15.1.1) or ascorbate peroxidase (cytapx) (EC 1.11.1.1) alone, or in combination, were produced and tested for tolerance against mild water stress. The results showed that the simultaneous overexpression of Cu/Znsod and apx or at least apx in the cytosol of transgenic tobacco plants alleviates, to some extent, the damage produced by water stress conditions. This was correlated with higher water use efficiency and better photosynthetic rates. In general, oxidative stress parameters, such as lipid peroxidation, electrolyte leakage, and H2O2 levels, were higher in non-transformed plants than in transgenic lines, suggesting that, at the least, overexpression of cytapx protects tobacco membranes from water stress. In these conditions, the activity of other antioxidant enzymes was induced in transgenic lines at the subcellular level. Moreover, an increase in the activity of some antioxidant enzymes was also observed in the chloroplast of transgenic plants overexpressing cytsod and/or cytapx. These results suggest the positive influence of cytosolic antioxidant metabolism on the chloroplast and underline the complexity of the regulation network of plant antioxidant defences during drought stress.

AB Soybeans (Glycine max Merr.) were grown at elevated carbon dioxide concentration ([CO(2)]) or chronic elevated ozone concentration ([O(3)]; 90 ppb), and then exposed to an acute O(3) stress (200 ppb for 4 h) in order to test the hypothesis that the atmospheric environment alters the total antioxidant capacity of plants, and their capacity to respond to an acute oxidative stress. Total antioxidant metabolism, antioxidant enzyme activity, and antioxidant transcript abundance were characterized before, immediately after, and during recovery from the acute O(3) treatment. Growth at chronic elevated [O(3)] increased the total antioxidant capacity of plants, while growth at elevated [CO(2)] decreased the total antioxidant capacity. Changes in total antioxidant capacity were matched by changes in ascorbate content, but not phenolic content. The growth environment significantly altered the pattern of antioxidant transcript and enzyme response to the acute O(3) stress. Following the acute oxidative stress, there was an immediate transcriptional reprogramming that allowed for maintained or increased antioxidant enzyme activities in plants grown at elevated [O(3)]. Growth at elevated [CO(2)] appeared to increase the response of antioxidant enzymes to acute oxidative stress, but dampened and delayed the transcriptional response. These results provide evidence that the growth environment alters the antioxidant system, the immediate response to an acute oxidative stress, and the timing over which plants return to initial antioxidant levels. The results also indicate that future elevated [CO(2)] and [O(3)] will differentially affect the antioxidant system.

AB Avian metapneumovirus (AMPV) is a paramyxovirus that principally causes respiratory disease and egg production drops in turkeys and chickens. Together with its closely related human metapneumovirus (HMPV), they comprise the genus Metapneumovirus in the family Paramyxoviridae. Little is currently known about the mechanisms involved in the budding of metapneumovirus. By using AMPV as a model system, we showed that the matrix (M) protein by itself was insufficient to form virus-like-particles (VLPs). The incorporation of M into VLPs was shown to occur only when both the viral nucleoprotein (N) and the fusion (F) proteins were co-expressed. Furthermore, we provided evidence indicating that two YSKL and YAGL segments encoded within the M protein were not a functional late domain, and the endosomal sorting complex required for transport (ESCRT) machinery was not involved in metapneumovirus budding, consistent with a recent observation that human respiratory syncytial virus, closely related to HMPV, uses an ESCRT-independent budding mechanism. Taken together, these results suggest that metapneumovirus budding is independent of the ESCRT pathway and the minimal budding machinery described here will aid our future understanding of metapneumovirus assembly and egress.

AB It is estimated that in the next 20 years, the amount of people greater than 65 years of age will rise from 40 to 70 million, and will account for 19% of the total population Age-related decreases in muscle mass and function, known as sarcopenia, have been shown to be related to functional limitation, frailty and an increased risk of morbidity and mortality. Therefore, with an increasing elderly population, interventions that can improve muscle mass content and/or function are essential. However, analytical techniques used for measurement of muscle mass in young subjects may not be valid for use in the elderly. Therefore, the purpose of this review is to examine the applied specificity and accuracy of methods that are commonly used for measurement of muscle mass in aged subjects, and, to propose specific recommendations for the use of body composition measures in phase II clinical trials of function-promoting anabolic therapies.

AB Sarcopenia, the age-associated loss of skeletal muscle mass and function, has considerable societal consequences for the development of frailty, disability, and health care planning. A group of geriatricians and scientists from academia and industry met in Rome, Italy, on November 18, 2009, to arrive at a consensus definition of sarcopenia. The current consensus definition was approved unanimously by the meeting participants and is as follows: Sarcopenia is defined as the age-associated loss of skeletal muscle mass and function. The causes of sarcopenia are multifactorial and can include disuse, altered endocrine function, chronic diseases, inflammation, insulin resistance, and nutritional deficiencies. Although cachexia may be a component of sarcopenia, the 2 conditions are not the same. The diagnosis of sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health. Sarcopenia should specifically be considered in patients who are bedridden, cannot independently rise from a chair, or who have a measured gait speed less that 1 m/s(-1). Patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry with sarcopenia being defined using currently validated definitions. A diagnosis of sarcopenia is consistent with a gait speed of less than 1 m.s(-1) and an objectively measured low muscle mass (eg, appendicular mass relative to ht(2) that is <= 7.23 kg/m(2) in men and <= 5.67 kg/m(2) in women). Sarcopenia is a highly prevalent condition in older persons that leads to disability, hospitalization, and death. (J Am Med Dir Assoc 2011; 12: 249-256)

AB Background: Knowledge about adverse symptoms over time from fiber supplementation is lacking.
Purpose: The aim of this study was to compare the severity of adverse gastrointestinal (GI) symptoms during supplementation with dietary fiber or placebo over time in adults with fecal incontinence. A secondary aim was to determine the relationship between symptom severity and emotional upset and their association with study attrition and reducing fiber dose.
Methods: Participants (N = 189; 77% female; 92% White; age, M = 58 years, SD = 14 years) with fecal incontinence were randomly assigned to a placebo or a supplement of 16 g total dietary fiber per day from 1 of 3 sources: gum arabic, psyllium, or carboxymethylcellulose. They reported GI symptoms daily during baseline (14 days), incremental fiber dosing (6 days), and 2 segments of steady full fiber dose (32 days total).
Results: Severity of symptoms in all groups was minimal. Adjusting for study segment and day, a greater feeling of fullness in the psyllium group was the only symptom that differed from symptoms in the placebo group. The odds of having greater severity of flatus, belching, fullness, and bloating were 1.2-2.0 times greater in the steady dose segment compared with baseline. There was a positive association between symptom severity and emotional upset. Participants with a greater feeling of fullness or bloating or higher scores for total symptom severity or emotional upset were more likely to withdraw from the study sooner or reduce fiber dose.
Conclusions: Persons with fecal incontinence experience a variety of GI symptoms over time. Symptom severity and emotional upset appear to influence fiber tolerance and study attrition. Supplements seemed well tolerated.

AB The electronic nose (e-nose) is designed to crudely mimic the mammalian nose in that most contain sensors that non-selectively interact with odor molecules to produce some sort of signal that is then sent to a computer that uses multivariate statistics to determine patterns in the data. This pattern recognition is used to determine that one sample is similar or different from another based on headspace volatiles. There are different types of e-nose sensors including organic polymers, metal oxides, quartz crystal microbalance and even gas-chromatography (GC) or combined with mass spectroscopy (MS) can be used in a non-selective manner using chemical mass or patterns from a short GC column as an e-nose or "Z" nose. The electronic tongue reacts similarly to non-volatile compounds in a liquid. This review will concentrate on applications of e-nose and e-tongue technology for edible products and pharmaceutical uses.

AB Background and Aims Cytokinins are a major group of plant hormones and are associated with various developmental processes. Developing caryopses of maize have high levels of cytokinins, but little is known about their spatial and temporal distribution. The localization and quantification of cytokinins was investigated in maize (Zea mays) caryopsis from 0 to 28 d after pollination together with the expression and localization of isopentenyltransferase ZmIPT1 involved in cytokinin biosynthesis and ZmCNGT, the gene putatively involved in N9-glucosylation.
Methods Biochemical, cellular and molecular approaches resolved the overall cytokinin profiles, and several gene expression assays were used for two critical genes to assess cytokinin cell-specific biosynthesis and conversion to the biologically inactive form. Cytokinins were immunolocalized for the first time in maize caryopses.
Key Results During the period 0-28 d after pollination (DAP): (1) large quantities of cytokinins were detected in the maternal pedicel region relative to the filial tissues during the early stages after fertilization; (2) unpollinated ovules did not accumulate cytokinins; (3) the maternal nucellar region showed little or no cytokinin signal; (4) the highest cytokinin concentrations in filial endosperm and embryo were detected at 12 DAP, predominantly zeatin riboside and zeatin-9-glucoside, respectively; and (5) a strong cytokinin immuno-signal was detected in specific cell types in the pedicel, endosperm and embryo.
Conclusions The cytokinins of developing maize caryopsis may originate from both local syntheses as well as by transport. High levels of fertilization-dependent cytokinins in the pedicel suggest filial control on metabolism in the maternal tissue; they may also trigger developmental programmed cell death in the pedicel.

AB Western North America is experiencing a dramatic expansion of pion (Pinus spp.) and juniper (Juniperus spp.) (P-J) trees into shrub-steppe communities. Feature extracted data acquired from remotely sensed imagery can help managers rapidly and accurately assess this land cover change in order to manage rangeland ecosystems at a landscape-scale. The objectives of this study were to: (1) develop an effective and efficient method for accurately quantifying P-J tree canopy cover and density directly from high resolution photographs and (2) compare feature-extracted data to typical in-situ datasets used by land managers. Tree cover was extracted from aerial-photography using Feature Analyst(A (R)). Tree density was calculated as the sum of the total number of individual polygons (trees) within the tree cover output file after isolation using a negative buffer post-processing technique. Feature-extracted data were compared to ground reference measurements from Utah's Division of Wildlife Resources Range Trend Project (DWR-RTP). We found that the proposed feature-extraction techniques used for measuring cover and density were highly correlated to ground reference and DWR-RTP datasets. Feature-extracted measurements of cover generally showed a near 1:1 relationship to these data, while tree density was underestimated; however, after calibration for juvenile trees, a near 1:1 relationship was realized. Feature-extraction techniques used in this study provide an efficient method for assessing important rangeland indicators, including: density, cover, and extent of P-J tree encroachment. Correlations found between field and feature-extracted data provide evidence to support extrapolation between the two approaches when assessing woodland encroachment.

AB The prevalence of Campylobacter (>90%) and Salmonella (33%) in turkeys at slaughter has been estimated. This report describes studies to estimate the time of entry of Campylobacter and Salmonella into the brooder house, which is the first stage of commercial turkey production. In trial 1, birds (similar to 100 per time point) were monitored by conventional culture at three intervals (0, 9, and 16 days of age). Campylobacter spp. were not detected in poults at the day of hatch; Salmonella was isolated from the ceca (3.9%) and yolk sac (0.1%). By day 9, Salmonella were frequently isolated from the ceca (55%) and small intestine (45%) while Campylobacter was not cultured. By day 16, the prevalence of Salmonella in the ceca (21%) and small intestine (5.1%) had declined; Campylobacter was infrequently isolated from either the ceca (2%) or small intestine (3%). In trial 2, poults (50 per time point at 5, 20, and 33 days of age) were monitored for Campylobacter and Salmonella by real-time polymerase chain reaction (PCR); Salmonella was also monitored by conventional culture. Whereas Campylobacter was not detected by real-time PCR in the ceca of 5-day-old birds, it was detected on days 20 (92%) and 33 (90%). In contrast, Salmonella was isolated from young birds at days 5 (98%), 20 (98%), and 33 (98%), after which time the turkeys were moved to the finisher house. At slaughter at 138 days, Salmonella prevalence in the ceca had declined (4.5%) in contrast to the prevalence of Campylobacter (92%). Antimicrobial sensitivity profiles of the Salmonella isolates indicated an increase of sulfonamide-resistant isolates throughout the brooder stage. Genotyping by pulsed-field gel electrophoresis analysis of Salmonella (45 isolates per sampling time) indicated fluctuating populations as the birds matured.

AB In maize, mutations in the pr1 locus lead to the accumulation of pelargonidin (red) rather than cyanidin (purple) pigments in aleurone cells where the anthocyanin biosynthetic pathway is active. We characterized pr1 mutation and isolated a putative F3'H encoding gene (Zmf3'h1) and showed by segregation analysis that the red kernel phenotype is linked to this gene. Genetic mapping using SNP markers confirms its position on chromosome 5L. Furthermore, genetic complementation experiments using a CaMV 35S::ZmF3'H1 promoter-gene construct established that the encoded protein product was sufficient to perform a 3'-hydroxylation reaction. The Zmf3'h1-specific transcripts were detected in floral and vegetative tissues of Pr1 plants and were absent in pr1. Four pr1 alleles were characterized: two carry a 24 TA dinucleotide repeat insertion in the 5'-upstream promoter region, a third has a 17-bp deletion near the TATA box, and a fourth contains a Ds insertion in exon1. Genetic and transcription assays demonstrated that the pr1 gene is under the regulatory control of anthocyanin transcription factors red1 and colorless1. The cloning and characterization of pr1 completes the molecular identification of all genes encoding structural enzymes of the anthocyanin pathway of maize.

AB A plant regeneration protocol was developed for white ash (Fraxinus americana L.). Hypocotyls and cotyledons excised from embryos were cultured on Murashige and Skoog (MS) medium supplemented with 6-benzylaminopurine (BA) plus thidiazuron (TDZ), and compared for organogenic potential. Sixty-six percent of hypocotyl segments and 10.4% of cotyledon segments produced adventitious shoots, with a mean number of adventitious shoots per explant of 3.5 +/- 0.9 and 2.5 +/- 1.5, respectively. The best regeneration medium (52% shoot formation; 47% shoot elongation) for hypocotyls was MS basal medium containing 22.2 mu M BA plus 0.5 mu M TDZ, producing a mean of 3.9 +/- 0.4 adventitious shoots. Adventitious shoots were established as proliferating shoot cultures following transfer to MS medium with Gamborg B5 vitamins supplemented with 10 mu M BA plus 10 mu M TDZ. For in vitro rooting, woody plant medium with indole-3-acetic acid (IAA) at 0, 2.9, 5.7, or 8.6 mu M in combination with 4.9 mu M indole-3-butyric acid (IBA) was tested for a 5- or 10-d dark culture period, followed by culture under a 16-h photoperiod. The best rooting (78% to 81%) of in vitro shoots was obtained with a 5 d dark culture treatment on medium containing 2.9 or 5.7 mu M IAA plus 4.9 mu M IBA, with an average of 2.6 +/- 0.4 roots per shoot. Rooted plants were successfully acclimatized to the greenhouse. This adventitious shoot regeneration and rooting protocol will be used as the basis for experimental studies to produce transgenic white ash with resistance to the emerald ash borer.

AB Biomass pyrolysis is a fundamental thermochemical conversion process that is of both industrial and ecological importance. From designing and operating industrial biomass conversion systems to modeling the spread of wildfires, an understanding of solid state pyrolysis kinetics is imperative. A critical review of kinetic models and mathematical approximations currently employed in solid state thermal analysis is provided. Isoconversional and model-fitting methods for estimating kinetic parameters are comparatively evaluated. The thermal decomposition of biomass proceeds via a very complex set of competitive and concurrent reactions and thus the exact mechanism for biomass pyrolysis remains a mystery. The pernicious persistence of substantial variations in kinetic rate data for solids irrespective of the kinetic model employed has exposed serious divisions within the thermal analysis community and also caused the broader scientific and industrial community to question the relevancy and applicability of all kinetic data obtained from heterogeneous reactions. Many factors can influence the kinetic parameters, including process conditions, heat and mass transfer limitations, physical and chemical heterogeneity of the sample, and systematic errors. An analysis of thermal decomposition data obtained from two agricultural residues, nutshells and sugarcane bagasse, reveals the inherent difficulty and risks involved in modeling heterogeneous reaction systems.

AB The California lettuce and leafy greens industry has adopted the Leafy Greens Marketing Agreement (LGMA), which allows for 126 most-probable-number (MPN) Escherichia coli per 100 ml in irrigation water. Repeat irrigation of baby spinach plants with water containing E. coli O157:H7 and different levels of total organic carbon (TOC) was used to determine the epiphytic survival of E. coli O157:H7. Three irrigation treatments (0 ppm of TOC, 12 or 15 ppm of TOC, and 120 or 150 ppm of TOC) were prepared with bovine manure containing E. coli O157:H7 at either low (0 to I log CFU/100 ml) or high (5 to 6 log CFU/100 ml) populations, and sprayed onto baby spinach plants in growth chambers by using a fine-mist airbrush. MPN and direct plating techniques were used to determine the E. coli O157:H7 populations on the aerial plant tissue. Plants irrigated with high E. coli O157:H7 populations, regardless of TOC levels, showed a 3-log reduction within the first 24 h. Low levels of E. coli O157:H7 were observed for up to 16 days on all TOC treatments, ranging from 76.4 MPN per plant (day 1) to 0.40 MPN per plant (day 16). No viable cells were detected on spinach tissue 24 h after irrigation with water containing fewer than 126 CFU/100 ml E. coli O157:H7. Under growth chamber conditions in this study, E. coli O157:H7 populations in irrigation water that complies with the LGMA standards will not persist for more than 24 h when applied onto foliar surfaces of spinach plants.

AB Fresh-cut leafy greens contaminated with Escherichia coli O157:H7 have caused foodborne outbreaks. Packaging conditions, coupled with abusive storage temperatures of contaminated lettuce, were evaluated for their effect on the potential virulence of E. coli O157:H7. Shredded lettuce was inoculated with 5.58 and 3.98 log CFU E. coli O157:H7 per g and stored at 4 and 15 degrees C, respectively, for up to 10 days. Lettuce was packaged under treatment A (modified atmosphere packaging conditions used for commercial fresh-cut produce, in gas-permeable film with N(2)), treatment B (near ambient air atmospheric conditions in a gas-permeable film with microperforations), and treatment C (high-CO(2) and low-O(2) conditions in a gas-impermeable film). E. coli O157:H7 populations from each treatment were determined by enumeration of numbers on MacConkey agar containing nalidixic acid. RNA was extracted from packaged lettuce for analysis of expression of virulence factor genes stx(2), eae, ehxA, iha, and rfbE. E. coli O157:H7 populations on lettuce at 4 degrees C under all treatments decreased, but most considerably so under treatment B over 10 days. At 15 degrees C, E. coli O157:H7 populations increased by at least 2.76 log CFU/g under all treatments. At 15 degrees C, expression of eae and iha was significantly greater under treatment B than it was under treatments A and C on day 3. Similarly, treatment B promoted significantly higher expression of stx(2), eae, ehxA, and rfbE genes on day 10, compared with treatments A and C at 15 degrees C. Results indicate that storage under near ambient air atmospheric conditions can promote higher expression levels of O157 virulence factors on lettuce, and could affect the severity of E. coli O157:H7 infections associated with leafy greens.

AB The zoonotic bacteria Salmonella enterica, Listeria monocytogenes, and Escherichia coli are known to infect dairy cows while not always causing clinical signs of disease. These pathogens are sometimes found in raw milk, and human disease outbreaks due to these organisms have been associated with the consumption of raw milk or raw milk products. Bulk tank milk (BTM) samples (536) and in-line milk filters (519) collected from dairy farms across the United States during the National Animal Health Monitoring System's Dairy 2007 study were analyzed by real-time PCR for the presence of S. enterica and pathogenic forms of E. coli and by culture techniques for the presence of L. monocytogenes. S. enterica was detected in samples from 28.1% of the dairy operations, primarily in milk filters. Salmonella was isolated from 36 of 75 PCR-positive BTM samples and 105 of 174 PCR-positive filter samples, and the isolates were serotyped. Cerro, Kentucky, Muenster, Anatum, and Newport were the most common serotypes. L. monocytogenes was isolated from 7.1% of the dairy operations, and the 1/2a complex was the most common serotype, followed by 1/2b and 4b (lineage 1). Shiga toxin genes were detected in enrichments from 15.2% of the BTM samples and from 51.0% of the filters by real-time PCR. In most cases, the cycle threshold values for the PCR indicated that toxigenic strains were not a major part of the enrichment populations. These data confirm those from earlier studies showing significant contamination of BTM by zoonotic bacterial pathogens and that the consumption of raw milk and raw milk products presents a health risk.

AB Calibration of the soil conditioning index (SCI) to a diversify of field studies with known changes in soil organic carbon (SOC) would improve the usefulness of the SCI by the USDA Natural Resources Conservation Service to assess the environmental services provided by agricultural land stewardship. Our objectives were to (1) calibrate SCI scores against SOC from published field studies in the Midwest and (2) compare the calibration with a recently derived calibration from the southeastern United States. We found that SOC sequestration (at 25 +/- 6 cm [10 +/- 2 in] depth) could be reliably related to SCI across a diversity of studies in the region using the regression slope: 4.52 Mg C ha(-1) SCI(-1) (2.02 tn ac(-1) SCI(-1)), which translated into a rate of 0.35 +/- 0.06 Mg C ha(-1) y(-1) SCI(-1) (314 57 lb ac(-1) yr(-1) SCI(-1)), which is the mean +/- standard error of 18 slope estimates. Calibration slopes did not vary significantly between the Midwest and southeastern United States, resulting in a combined calibration of 0.29 +/- 0.03 Mg C ha(-1) y(-1) SCI(-1) (255 (+/-) 30 lb ac(-1) yr(-1) SCI(-1)), which is the mean +/- standard error of 49 slope estimates. The calibration of SCI scores to SOC will allow SCI to become a quantitative tool for natural resource professionals to predict SOC sequestration for farmers wanting to adopt conservation practices.

AB Reclamation research has shifted from short- to long-term assessment of mine land reclamation management strategies, wherein previously established study sites are revisited. In this study, we assessed long-term (28 y) relations among reestablished plant communities (production and diversity), replaced soil depth following mining (0.2 to 1.4 m [0.7 to 4.6 ft]), and restored slope position (5% north slope, 2% south) for three different subsoil types (A, B, C; characterized by 43%, 23%, and 14% clay, respectively) on a previously established soil wedge experiment in North Dakota (Merrill et al. 1998). Nonnative seeded species such as crested wheatgrass (Agropyron cristatum) and smooth brome (Bromus incrntus) had close to 50% persistence after 28 y, while less aggressive seeded species, such as Russian wildrye (Psathyrostachys juncea) and alfalfa (Medicago sativa), were more susceptible to invasion by other species leading to greater plant community diversity (Shannon's Diversity Index [H' = 1.348 and 1.717, respectively]).The most significant plant productivity response to soil depth/topographic position was observed for subsoil C on the south facing 2% slope (r(2) = 0.43; p = 0.03).The two soil parameters measured in this study (electrical conductivity and pH) indicated mine soil profile development through time for both slope position and subsoil type. Specific relations observed in this long-term study were somewhat more difficult to identify compared to earlier short-term studies conducted on this site, providing strong evidence that replaced soil depths should be determined based on soil stabilization and initial establishment of diverse, sustainable plant communities to reduce invasion of undesirable plant species.

AB Despite the health benefits, vegetable intake in youth remains below recommended levels. The purpose of our study was to compare two methods for increasing vegetable consumption. It was hypothesized that participants randomized to both the exposure-only and the pairing condition would increase their vegetable consumption and increase the variety of vegetables consumed. A total of 78 Mexican-American middle school-aged children from a charter school in Houston, TX, were randomized to a pairing condition (n=40) or an exposure-only condition (n=38) during the Spring 2009 semester. Children in the pairing condition were provided a preferred taste (peanut butter) paired with vegetables weekly at school during a nutrition class for 4 months. Children in the exposure-only condition received vegetables weekly during a nutrition class that covered the same material as the pairing condition. After 4 months, the pairing condition participants demonstrated significant increases in vegetable consumption (F=13.40, P<0.001) as well as variety of vegetables eaten (F=13.69, P<0.001) when compared to those in the exposure-only condition. The findings of this study suggest that the pairing of vegetables with a preferred taste, such as peanut butter, may be an effective technique in increasing consumption, especially in children who report being resistant to eating vegetables.

AB Recent studies have revealed several examples of intimate associations between insects and Actinobacteria, including the Southern Pine Beetle Dendroctonus frontalis and the Spruce Beetle Dendroctonus rufipennis. Here, we surveyed Streptomyces Actinobacteria co-occurring with 10 species of Dendroctonus bark beetles across the United States, using both phylogenetic and community ecology approaches. From these 10 species, and 19 other scolytine beetles that occur in the same trees, we obtained 154 Streptomyces-like isolates and generated 16S sequences from 134 of those. Confirmed 16S sequences of Streptomyces were binned into 36 distinct strains using a threshold of 0.2% sequence divergence. The 16S rDNA phylogeny of all isolates does not correlate with the distribution of strains among beetle species, localities, or parts of the beetles or their galleries. However, we identified three Streptomyces strains occurring repeatedly on Dendroctonus beetles and in their galleries. Identity of these isolates was corroborated using a house-keeping gene sequence (efTu). These strains are not confined to a certain species of beetle, locality, or part of the beetle or their galleries. However, their role as residents in the woodboring insect niche is supported by the repeated association of their 16S and efTu from across the continent, and also having been reported in studies of other subcortical insects.

AB Hypocrea peltata (Pezizomycotina, Hypocreales, Hypocreaceae) is a common, widespread essentially subtropical species, with an uncharacteristically large stroma and asci containing four large and four small bicellular ascospores. Its only anamorph consists of indehiscent aleuriospores; it does not form a Trichoderma anamorph, which is typical of most Trichoderma Hypocrea species..Hypocrea peltata grows very well at 37 C. The large stromata and failure to form a Trichoderma anamorph could lead one to doubt its generic placement. However sequences of the internal transcribed spacer region (ITS), 28S nuclear large subunit (LSU) of rDNA and RNA polymerase subunit II (rpb2) regions indicate that it represents a unique lineage within Trichoderma/Hypocrea. ITS and rbp2 sequences derived from cultures of H. peltata are identical to the "unidentified Hypocreaceae" reported in the literature as being isolated from lung of a patient with non-fatal pulmonary fibrosis.

ID POLICY; CONSEQUENCES; JUDGMENT; BIASES; COSTS
AB Managing wildfire events to achieve multiple management objectives involves a high degree of decision complexity and uncertainty, increasing the likelihood that decisions will be informed by experience-based heuristics triggered by available cues at the time of the decision. The research reported here tests the prevalence of three risk-based biases among 206 individuals in the USDA Forest Service with authority to choose how to manage a wildfire event (i.e., line officers and incident command personnel). The results indicate that the subjects exhibited loss aversion, choosing the safe option more often when the consequences of the choice were framed as potential gains, but this tendency was less pronounced among those with risk seeking attitudes. The subjects also exhibited discounting, choosing to minimize short-term over long-term risk due to a belief that future risk could be controlled, but this tendency was less pronounced among those with more experience. Finally, the subjects, in particular those with more experience, demonstrated a status quo bias, choosing suppression more often when their reported status quo was suppression. The results of this study point to a need to carefully construct the decision process to ensure that the uncertainty and conflicting objectives inherent in wildfire management do not result in the overuse of common heuristics. Individual attitudes toward risk or an agency culture of risk aversion may counterbalance such heuristics, whereas increased experience may lead to overconfident intuitive judgments and a failure to incorporate new and relevant information into the decision.

ID HYDRAULIC CONDUCTIVITY; AVAILABLE WATER; RETENTION; LIMITS; LAND
AB Field capacity or field water capacity (FC) is defined as the water content of a soil following saturation with water and aft er free drainage is negligible. Different recommendations exist worldwide on which, if any, pressure should be used in laboratory measurements to approximate the FC of the soil. Research has oft en deemed any such pressures to be inadequate to approximate FC for soils of all textures. We used a data collection from the literature to evaluate if corrections can be made to improve the estimation of FC from -33 kPa water retention (W33). Regression tree modeling coupled with jack-knife cross-validation was used to identify the best predictors-sand, silt, clay and the measured W33 value-to estimate the difference between W33 and FC. Such predictions were then used to adjust the W33 value as the estimate of FC. An improvement in estimating FC was seen in general statistical terms, and texture-specific bias was also greatly reduced. This solution may allow the reliable use of a single pressure in the laboratory to approximate FC, which may be the only feasible option for large-scale studies.

AB Previous studies indicate that biochar additions sometimes increase soil respiration and CO(2) emissions which could partially off set C credits associated with soil biochar applications. Little is known, however, about the impact of biochar on the mineralization of manure in soil systems and how interactions between biochar and manure impact C sequestration and greenhouse gas (GHG) emissions from soils. We studied the effect of biochar and dried swine manure additions on changes in soil bulk density (D(b)), total soil organic carbon (SOC), and emissions of N(2)O and CO(2) during a 500-d soil column incubation study. The addition of biochar to the soil increased SOC content measured aft er the 500-d incubation by 17.6 to 68.8%, depending on the treatment. Biochar additions reduced N(2)O emissions measured once near the end of the incubation. The N(2)O emissions were weakly correlated with D(b), suggesting that enhanced soil aeration contributed to the reductions in N(2)O emissions. Biochar additions consistently increased CO(2) emissions (measured 13 times during the incubation) relative to no-biochar controls with cumulative CO(2)-C emissions equivalent to 17 to 23% of biochar C applied. However, a distinct biochar-by-manure interaction for CO(2) flux indicated that biochar either helped stabilize manure C or the presence of manure reduced the effect of biochar on the mineralization of SOC. For the studied system, we conclude that biochar additions sequestered large amounts of highly stable C, reduced N(2)O emissions, increased CO(2) emissions from the soils, and reduced rates of CO(2) emissions following a manure addition.

AB Windblown sediment resulting from erosion of agricultural land has impaired visibility and threatened human health in the U. S. Inland Pacific Northwest. There is, however, a lack of information on the size distribution of windblown sediment originating from these lands. Passive collectors were used to trap windblown sediment from heights of 0 to 1.5 m above eroding agricultural fields. Sediment collected during one high-wind event in each of 7 yr was separated into <= 10-, 11- to 32-, 33- to 45-, 46- to 100-, and >100-mu m-diameter size fractions. Windblown sediment trapped nearer the soil surface was more characteristic of the erodible portion of the in situ parent soil. Vertical size gradation of windblown sediment was evidenced by a decrease in mass of the 46- to 100- and >100-mu m size fractions and increase in mass of the <= 10- and 11- to 32-<=mu m size fractions with height from the soil surface. Trends in the sediment size distribution with height suggested that sediment <= 32 mu m in diameter was transported primarily by suspension, sediment 33 to 45 mu m in diameter was transported by saltation and suspension, and sediment >45 mu m in diameter was transported primarily by creep and saltation. In addition, the size of windblown sediment observed at all heights above the soil surface was found to increase with increasing wind velocity. A large fraction of windblown sediment was comprised of suspension-sized aggregates and particles, thus mitigation strategies to control wind erosion in the Columbia Plateau must promote aggregation of the suspension component (<= 32-mu m diameter) of the parent soil or shelter the suspension component at the soil surface from high winds.

AB Recent efforts have attempted to establish emission estimates for greenhouse gas (GHGs) from agricultural soils in the United States. This research project was conducted to assess the influence of cropping system management on non-CO(2) GHG emissions from an eastern Corn Belt Alfisol. Corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotation plots were established, as were plots in continuous management of native grasses or sorghum-sudan-grass [Sorghum bicolor (L.) Moench nothossp. drummondii (Steud.) de Wet ex Davidse]. Greenhouse gas fluxes were monitored throughout each growing season from 2004 through 2007. Fluxes of N(2)O were significantly correlated with soil temperature (P < 0.001), and thus a temperature (Q(10)) correction was made (3.48 for N(2)O). Nitrous oxide emissions from corn were lowest from the precision tillage treatment (2.4 kg N ha(-1) yr(-1)), significantly lower than the conventional tillage (4.9 kg N ha(-1) yr(-1)) or cover crop corn treatments (5.0 kg N ha(-1) yr(-1)). Corn-soybean and biomass-based cropping systems resulted in significantly greater N(2)O emissions than native grasses. There was a positive correlation between the N fertilization rate and N(2)O emissions when comparing all treatments in this study. These soils were typically a sink for atmospheric CH(4) for these cropping systems, and thus N(2)O is the primary non-CO(2) GHGs of concern. When evaluating the entire cropping system, native grasses resulted in the lowest N(2)O emissions, while a corn-soybean rotation planted with precision tillage resulted in N(2)O emissions similar to bare soil and were significantly lower than emissions from the other cropping systems assessed.

AB The impact of a linear, high molecular weight, moderate negative charge density polyacrylamide (PAM) on soil hydraulic conductivity (HC) and the mechanisms involved are partially understood. Our objectives were to evaluate the impact of (i) electrolyte concentration of the PAM solution, (ii) mode of PAM application, and (iii) drying of the applied PAM solution on the HC of a fine sand and a silt loam. We exposed the two media to (i) leaching with deionized water (DW) or a 0.01 mol L(-1) CaCl(2) solution, both containing 25 mg L(-1) PAM, and (ii) leaching with DW aft er addition of either 2 g m(-2) of dry PAM granules (with or without gypsum) to the soil surface, or an equivalent amount of PAM in solution (with or without drying) to the soil column before leaching. For both media, leaching the columns with DW containing PAM resulted in a significantly lower steady-state HC (HCss, <0.10 cm h(-1)) than the HCss obtained for leaching with DW only. In the silt loam, replacing the PAM in the 0.01 mol L(-1) CaCl(2) solution with DW resulted in a moderate decline in the HC. Leaching the soil with DW aft er adding granular PAM to the surface resulted in a HCss of 0.18 cm h(-1), while aft er adding a concentrated PAM solution the HCss was 0.11 cm h(-1). Drying of the added PAM solution before leaching led to a twofold increase in the HCss. The adverse impact of PAM on the HC was ascribed to the extension of the unadsorbed segments of the PAM chains into the pores, thus creating a drag on the flowing water.

ID SYSTEM; PERFORMANCE
AB For several years, many types of solar powered water pumping systems were evaluated, and in this paper, diaphragm and helical solar photovoltaic (PV) powered water pumping systems are discussed. Data were collected on diaphragm and helical pumps which were powered by different solar PV arrays at multiple pumping depths to determine the pumping performance, efficiency, and reliability of the different systems. The highest diaphragm pump hydraulic efficiency measured was similar to 48%, and the highest helical pump hydraulic efficiency measured was similar to 60%. The peak total system efficiency (e.g. solar radiation to pumped water) measured for the diaphragm and helical pumps were similar to 5% and similar to 7%, respectively (based on PV modules with similar to 12% efficiency). The daily water volume of the three-chamber high head diaphragm pump performed better than the dual-chamber high head diaphragm pump (similar to 5 to similar to 100% depending on PV array input power and pumping depth). Use of a controller was shown to improve the quad diaphragm pump performance below a solar irradiance of 600 W/m(2) (20 m head) to 800 W/m(2) (30 m head). While diaphragm pumps made mostly of plastic demonstrated similar to much better pumping performance than diaphragm pumps made with a high proportion of metal, the metal pumps demonstrated a longer service life (>2 years) than the plastic pumps service life (<2 years). Helical pumps analyzed in this paper were capable of deeper pumping depths and usually demonstrated a longer service life than the diaphragm pumps that were analyzed. Published by Elsevier Ltd.

AB Lysozyme was attached to three cotton fabrics through a glycine amino acid linker esterified to cotton cellulose. Lysozyme bound to cotton twill using a carbodiimide-mediated coupling reaction gave the best lysozyme incorporation (16.1 mg/g of cotton). Cotton spunlace nonwoven fabric bound slightly less lysozyme (12.8 mg/g of cotton), but had the best antimicrobial activity. Woven print cloth bound the least lysozyme (4 mg/g of cotton). Characterization of lysozyme on the fabric was performed using Fourier transform infrared and nitrogen analysis. Increases in amide I and amide II infrared frequencies were evident with increased lysozyme incorporation. Lysozyme-cellulose conjugate activity was assessed with a turbidity clearing assay using Micrococcus lysodeikticus. The order of lysozyrne-fabric antimicrobial activity was nonwoven > twill > print cloth.

AB Biotype 2 (BT2) variants of the bacterium Yersinia ruckeri are an increasing disease problem in U. S. and European aquaculture and have been characterized as serovar 1 isolates that lack both peritrichous flagella and secreted phospholipase activity. The emergence of this biotype has been associated with an increased frequency of enteric redmouth disease (ERM) outbreaks in previously vaccinated salmonid fish. In this study, four independent specific natural mutations that cause the loss of both motility and secreted lipase activity were identified in BT2 strains from the United States, United Kingdom, and mainland Europe. Each of these was a unique mutation in either fliR, flhA, or flhB, all of which are genes predicted to encode essential components of the flagellar secretion apparatus. Our results demonstrate the existence of independent mutations leading to the BT2 phenotype; thus, this phenotype has emerged separately at least four times. In addition, BT2 strains from the United Kingdom were shown to have the same mutant allele found in U. S. BT2 strains, suggesting a common origin of this BT2 lineage. This differentiation of distinct BT2 lineages is of critical importance for the development and validation of alternative vaccines or other treatment strategies intended for the control of BT2 strains.

AB The net effects of soil biota on exotic invaders can be variable, in part, because net effects are produced by many interacting mutualists and antagonists. Here we compared mutualistic and antagonistic biota in soils collected in the native, expanded, and invasive range of the black locust tree, Robinia pseudoacacia. Robinia formed nodules in all soils with a broad phylogenetic range of N-fixing bacteria, and leaf N did not differ among the different sources of soil. This suggests that the global expansion of Robinia was not limited by the lack of appropriate mutualistic N-fixers. Arbuscular mycorrhizal fungi (AMF) from the native range stimulated stronger positive feedbacks than AMF from the expanded or invasive ranges, a biogeographic difference not described previously for invasive plants. Pythium taxa collected from soil in the native range were not more pathogenic than those from other ranges; however, feedbacks produced by the total soil biota were more negative from soils from the native range than from the other ranges, overriding the effects of AMF. This suggests that escape from other pathogens in the soil or the net negative effects of the whole soil community may contribute to superior performance in invaded regions. Our results suggest that important regional evolutionary relationships may occur among plants and soil biota, and that net effects of soil biota may affect invasion, but in ways that are not easily explained by studying isolated components of the soil biota.

AB Objective: The APOA2 gene has been associated with obesity and insulin resistance (IR) in animal and human studies with controversial results. We have reported an APOA2-saturated fat interaction determining body mass index (BMI) and obesity in American populations. This work aims to extend our findings to European and Asian populations.
Methods: Cross-sectional study in 4602 subjects from two independent populations: a high-cardiovascular risk Mediterranean population (n = 907 men and women; aged 67 +/- 6 years) and a multiethnic Asian population (n = 2506 Chinese, n = 605 Malays and n = 494 Asian Indians; aged 39 +/- 12 years) participating in a Singapore National Health Survey. Anthropometric, clinical, biochemical, lifestyle and dietary variables were determined. Homeostasis model assessment of insulin resistance was used in Asians. We analyzed gene-diet interactions between the APOA2 = 265T > C polymorphism and saturated fat intake (< or >= 22 g per day) on anthropometric measures and IR.
Results: Frequency of CC (homozygous for the minor allele) subjects differed among populations (1-15%). We confirmed a recessive effect of the APOA2 polymorphism and replicated the APOA2-saturated fat interaction on body weight. In Mediterranean individuals, the CC genotype was associated with a 6.8% greater BMI in those consuming a high (P - 0.018), but not a low (P = 0.316) saturated fat diet. Likewise, the CC genotype was significantly associated with higher obesity prevalence in Chinese and Asian Indians only, with a high-saturated fat intake (P = 0.036). We also found a significant APOA2-saturated fat interaction in determining IR in Chinese and Asian Indians (P 0.026).
Conclusion: The influence of the APOA2 -265T > C polymorphism on body-weight-related measures was modulated by saturated fat in Mediterranean and Asian populations. International Journal of Obesity (2011) 35, 666-675; doi: 10.1038/ijo.2010.187; published online 26 October 2010

AB Bone loss is a well-documented change during and after long-duration spaceflight. Many types of countermeasures to bone loss have been proposed, including vitamin K supplementation. The objective of this series of studies was to measure change in vitamin K status in response to microgravity under a variety of spaceflight and spaceflight analog (model) conditions, including long-duration spaceflight studies (n = 15), three bed rest studies (n = 15, 49, and 24), and a 14-day saturation dive (n = 6). In crew members who flew 2-6 months on the International Space Station, in-flight and postflight plasma phylloquinone concentrations were unchanged from the preflight mean. Consistent with this finding, urinary gamma-carboxyglutamic acid (GLA), a measure of vitamin K-dependent protein turnover, did not change in response to flight. Serum undercarboxylated osteocalcin (%ucOC), a measure of vitamin K function, was generally unchanged in response to flight. Spaceflight findings were corroborated by findings of no changes in phylloquinone, urinary GLA, or %ucOC during or after bed rest in three separate bed rest studies (21-90 days in duration) or after a 14-day saturation dive. The data presented here do not support either a need for vitamin K supplementation during spaceflight or the suggestion of using vitamin K as a bone loss countermeasure in spaceflight.

The Casuarina spp. are invasive plants in Florida that threaten biological diversity and beach integrity of coastal habitats. The trees include three species and their hybrids that aggressively invade riverine and coastal areas. Of the three species, C. equisetifolia and C. glauca are highly salt tolerant and widespread in coastal areas. The third species, C. cunninghamiana, invades riverine habitats. These species pose dangers to both the environment and public safety. The environmental damage includes interfering with nesting by endangered sea turtles, American crocodiles, and the rare swallow-tailed kite. Additionally, allelochemical leachates reduce germination and establishment of native vegetation. Casuarina-infested beaches are more prone to sand loss and erosion. Moreover, with shallow roots and tall canopies, they are among the first trees to fall in high winds and as such restrict evacuation efforts during hurricanes. Control of these species is mostly with herbicides, requiring repeated applications and monitoring. One of the most cost-effective means of controlling these invasive species would be with classical biological control. Australian surveys for potential biological control agents began in 2004, resulting in the discovery of several promising candidates. These include seed-feeding torymid wasps, defoliating caterpillars and weevils, leaf tip gall-formers from cecidomyiid midges, and sap-feeding psyllids. Continued work is needed to determine the suitability of these species for biological control. Despite conflicts of interest expressed by some homeowners and the agricultural industry who value the trees for shade and windbreaks, there are good prospects for safe and effective biological control of these invasive species.

AB alpha-Bisabolol, a natural plant sesquiterpene alcohol, and dragosantol, a racemic mixture of synthetic bisabolol, were studied for their fungicidal properties separately against the nongerminated and germinating conidia of several species of Aspergillus and Fusarium which represent problems in agriculture and medicine. Bactericidal assays against Pseudomonas aeruginosa and Staphylococcus aureus were also performed. Compared to the controls, both compounds displayed statistically significant (p < 0.001) lethality for the tested microorganisms. alpha-Bisabolol and dragosantol produced nearly 98% viability loss against the germinating conidia of A. flavus, A. fumigatus, A. niger, A. terreus, F. oxysporum, E solani, and E verticillioides (formerly E moniliforme) at, or below, 10 mu M. The viability of nongerminated E oxysporum conidia was significantly reduced. Both compounds showed very rapid and significant reduction of P. aeruginosa viability at 7.5 mu M. Staphylococcus aureus was more resistant to these compounds though significant viability loss occurred after 2 h incubation at 12.5 mu M. Minimum inhibition concentration studies (NCCIS Method-38A) showed that bisabolol inhibited the growth of clinical isolates of the dermatophytic pathogens Trichophyton tonsurans (2-8 mu g/mL), T. mentogrophytes (2-4 mu g/mL), T rubrum (0-1 mu g/mL) and Microsporum cants (0.5-2.0 mu g/mL). Results showed alpha-bisabolol and dragosantol have potent fungicidal and bactericidal properties against the tested strains. Because both compounds are safe for use in cosmetics, the data presented here suggest potential utility as antimicrobials in cosmetics, food and as a topical antifungal treatment.

AB Field tests were conducted to obtain irrigation evaluation and solute transport data. The data were used to calibrate and validate an advection-dispersion model for furrow irrigation. The empirical infiltration equation and roughness parameters were estimated from the evaluation data. The inflow rate was measured with a volumetric meter and a flume and resulted in different average inflow rates. Hydraulic simulation results proved nearly as accurate with infiltration function estimates derived from the meter or flume data despite the difference in measured flow rate. Hence, the calibrated infiltration functions provide limited clues about possible problems with the inflow data. The choice of the infiltration equation used to fit the data (Branch versus modified Kostiakov) produced greater differences in the hydraulic modeling results. The timing and spread of the solute concentration pulses were well predicted independently of the inflow data and infiltration equation used to fit the data. However, differences between the meter and flume inflow rate were clearly manifested in the predicted peak solute concentrations. Results highlight the importance of accurate inflow measurements for parameter estimation. DOI: 10.1061/(ASCE)IR.1943-4774.0000295. (C) 2011 American Society of Civil Engineers.

AB We report on the effect of nanoscale morphology on transport of ethanol/water mixtures through block copolymer membranes. In particular, we show that ethanol selectivity and overall flux can be optimized by varying the size of block copolymer domains at fixed composition. Experiments were conducted on two separate systems using polybutadiene (PB) and polydimethyl siloxane-g-polymethylmethacrylate (PDMS-MA) as the transporting blocks, using an 8 wt% ethanol/water mixture as the feed. The domain spacings for PB- and PDMS-MA-based samples were varied from 19 to 55 nm and 28 to 70 nm, respectively, at fixed compositions. The membrane separation factor increases with domain spacing for both membranes. In the case of the PB-based system, the smallest domain size system with d = 19 nm was water selective while those with larger domain spacings were ethanol selective. The total flux through the PB-based membranes increases with increasing domain spacing until it reaches a maximum at a domain spacing of 39 nm in spite of the fact that the stiffness of the polymers increases monotonically with increasing domain spacing. In contrast, the total flux through the PDMS-MA-based membranes does not depend on domain spacing. (C) 2011 Elsevier B.V. All rights reserved.

AB Tanning of animal hides produces leather, a durable, flexible material that is stabilized against putrefaction. Chrome-tanned wet blue, aldehyde crosslinked wet white, and vegetable tanned hides are major contributors to current leather production. Although the chemistries involved are significantly different, the product in each case is leather. Vegetable tanning, the oldest of these technologies is, from a mechanistic perspective, the least well understood. To explore possible vegetable tanning mechanisms, we have applied molecular modeling techniques to the study of interactions of gallotannin, a component of chestnut tannins, with the collagen microfibril. A model gallotannin molecule was constructed and energy minimized. This model was docked into several energetically favorable positions on a fragment of the ERRC collagen microfibril model, generally with a good fit at a proline or hydroxyproline residue. The alpha carbon backbone of collagen was kept immobile during molecular dynamics simulations at 400 - 800K with and without an added layer of water of solvation to identify possibly more favorable interactions sites for the gallotannin molecules. Both inter and intra chain interactions were possible, and several potential sites for hydrogen bonding via arginine residues or hydrophobic interactions with alanine or isoleucine residues were identified. The information gained from this model study is an early step in the development of a vegetable-tanning model.

AB The composition of the essential oils hydrodistilled from the aerial parts of five Achillea biebersteinii Afan samples, collected in central Turkey from Konya, Isparta and Ankara, were analyzed both by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Eighty-four components were identified, representing 87 to 99% of the total oil composition. The identified major components were 1,8-cineole (9-37%), camphor (16-30%) and p-cymene (1-27%). Two samples differed in piperitone (11%) and ascaridol (4%) content. The five A. biebersteinii essential oils were subsequently evaluated for their antifungal activity against the strawberry anthracnose-causing fungal plant pathogens Colletotrichum acutatum, C. fragariae and C. gloeosporioides using the direct overlay bioautography assay. The essential oils showed no antifungal activity at 80 and 160 mu g/spot. In addition, A. biebersteinii oils and their major compounds were subsequently investigated against Aedes aegypti first instar larvae in a high throughput bioassay. Among the oils, only one sample from Ankara showed a notable larvacidal effect on Ae. aegypti larvae. The major compounds, 1,8-cineole, camphor and p-cymene, exhibited low mosquito larval activity, and thus the minor compounds are probably responsible for the observed activity against Ae. aegypti larvae. The oils showed weak activity against adult Ae. aegypti.

AB Vesicular stomatitis viruses are the causative agents of vesicular stomatitis, an economically important contagious disease of livestock that occurs in North, Central, and South America. Little is known regarding the early stages of infection in natural hosts. Twelve adult Holstein steers were inoculated with Vesicular stomatitis New Jersey virus (VSNJV) on the coronary bands (CB) of the feet via scarification (SC) or by VSNJV-infected black fly (Simulium vittatum) bite (FB). Three additional animals were inoculated on the neck skin using FB. Clinical disease and lesion development were assessed daily, and animals were euthanatized from 12 hours post inoculation (HPI) through 120 HPI. The animals inoculated in the neck failed to develop any clinical signs or gross lesions, and VSNJV was detected neither by in situ hybridization (ISH) nor by immunohistochemistry (IHC). Lesions on the CB were more severe in the animals infected by FB than by SC. In both groups, peak VSNJV replication occurred between 24 and 48 HPI in keratinocytes of the CB, as evidenced by ISH and IHC. There was evidence of viral replication limited to the first 24 HPI in the local draining lymph nodes, as seen through ISH. Successful infection via FB required logarithmically less virus than with the SC technique, suggesting that components in black fly saliva may facilitate VSNJV transmission and infection in cattle. The lack of lesion development in the neck with the same method of inoculation used in the CB suggests that specific characteristics of the CB epithelium may facilitate VSNJV infection.

AB Before planting millions of hectares to switchgrass (Panicum virgatum L.) monocultures for producing biomass feedstock for biorefineries, it has been proposed that monocultures be tested against polycultures so, among other issues, the economics of both systems can be compared. This research was conducted to determine the lowest cost lignocellulosic biomass feedstock production system from among four monocultures and four polycultures. Randomized complete block designs with four replications were established at two Oklahoma locations. Plots were managed to represent anticipated production activities if perennial species were established in a low input system and harvested once a year to produce biorefinery feedstock. The four monocultures included switchgrass, sand bluestem (Andropogon hallii Hack.), Old World bluestem (OWB) (Bothriochloa ischaemum L. Keng), and big bluestem (A. gerardii Vitman). The four polycultures included mixtures of four grasses, four grasses and four forbs, eight grasses and eight forbs, and OWB with alfalfa (Medicago sativa L.). Plots were harvested once a year for 3 yr. For every treatment that included a mix of species, a dominant species emerged by the third harvest, suggesting that over time these treatments may not differ greatly from monocultures with minor representation of other species. The average yield was 4.6 Mg ha(-1)yr(-1) for treatments seeded as monocultures at one location compared with 4.0 Mg ha(-1)yr(-1) for the treatments seeded as polycultures. At the second location, monocultures averaged 7.9 Mg ha(-1)yr(-1) and polycultures 6.5 Mg ha(-1)yr(-1). Economics favored monocultures for the location and environmental conditions that occurred during the time period studied.

AB Efficient recycling of abundant manure resources from regional dairy industries in the semiarid West requires a better understanding of N availability in manure-amended soils. We measured net N mineralization using buried bags, and crop biomass, N uptake, and yields for sprinkler-irrigated, whole (noneroded) and eroded Portneuf soils (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) subject to a one-time manure application. Treatments included a control, fertilizer, two rates of composted dairy manure (28.4, 64.3 Mg ha(-1), dry wt.), and two rates of stockpiled dairy manure (23.3, 45.7 Mg ha(-1), dry wt.) applied in the fall before the Year 1 cropping season. Plots were planted to sugarbeet (Beta vulgaris L.), winter wheat (Triticum aestivum L.), and spring barley (Hordeum vulgare L.) during the 3-yr study. Overall, net N mineralization rates were low to moderate during winter through spring, decreased in early summer due to N immobilization, then increased to a maximum in late summer, followed by a decrease in fall. The mean mineralization rate (as a percentage of the added organic N) for Years 1, 2, and 3 was -4.2 (N immobilization), 4.3, and 4.8% for compost and 17.4, 17.0, and 11.4% for manure, respectively. Relative to controls, compost and manure treatments as a group increased total 3-yr net N mineralization more for eroded (1.77x) than for whole soils (1.55x). At higher rates, manure also increased immobilization and mineralization in 30-to60-cm soil depths (below the zone of incorporation). To optimize the use of N mineralized in southern Idaho's manure-amended soils, one should consider the type manure employed and the erosion status of the soil receiving the amendment.

AB Temporal variation in crop yields has considerable impact at farm, regional, and national levels. To gain a better understanding of the factors contributing to this variation, we quantified the cumulative effects of management practices and soil covariates on total yield (TY), temporal yield variance (TYV) and coefficient of variation (CV) of 2-yr (2 Yr) {corn [Zea mays L.]-soybean [Glycine max (L.) Merr.]} and 4-yr (4 Yr) [corn-soybean-spring wheat (Triticum aestivum L.)-alfalfa (Medicago sativa L.)] crop rotations in conventional (CNV) and organic (ORG) cropping systems. Soil covariates differed individually or as a group in their impact on TY, TYV, and CV. Spatial variation, quantified by soil covariates, did not fully explain variation in TY or TYV; whereas, TYV explained up to 86% of variation in TY, both of which were less variable in ORG than in CNV. Multivariate relationships among TYV, CV, management factors, and covariates indicated that TYs of 4-Yr crop rotations were likely to be more stable than TYs of 2-Yr rotations. The largest and most stable yields obtained under both cropping systems are characterized by a combination of optimum TYV and minimum CV values. We developed a classification scheme of cropping systems, crop rotation phases, and management practices based on the three-way relationship between TY, TYV, and CV, and deviations from their respective means. In addition to its utility in selecting the largest and most stable yield, the scheme can be used to measure stability in crop production and strategically deploy appropriate management practices for a given cropping system or crop rotation.

AB A Maturity Group (MG) IV and MG V soybean [Glycine max (L.) Merr.] cultivar were planted on beds in 102 cm single-rows or 25 cm twin-rows with 102 cm centers at 20, 30, 40, and 50 seeds m(-2) in a Beulah fine sandy loam (coarse-loamy, mixed, active, thermic Typic Dysrudepts) in 2008, 2009, and 2010 and in Sharkey clay (very-fine, smectitic, thermic Chromic Epiaquerts) in 2009 and 2010 at Stoneville, MS. Despite furrow irrigation, drought and consistent maximum temperatures -32 degrees C during 2010 reduced stands, yields, and seed weight at both sites. Twin-rows produced more plants than similar single-rows, which helped increase twin-rows yields compared to single-rows on the clay. Yields on the clay did not differ among seeding rates. Yields from twin-rows on the sandy loam were only greater than single-rows at 40 and 50 seeds m(-2) for the MG IV cultivar and did not differ for the MG V. The MG IV cultivar tended to yield better than the MG V at both sites. The MG IV cultivar averaged 20 nodes plant(-1) compared to 15 for the MG V. Both cultivars on the sandy loam average 59 pods plant(-1), while the MG V cultivar produced 70 pods plant(-1) vs. 63 pods plant(-1) for the MG IV cultivar on the clay. Twin-rows did not produce more pods plant(-1). Row type or seeding rate did not effect seed weight at either site. Seeds m(-2)were greater for the MG IV cultivar on the sandy loam and corresponded with yield, but not so on the clay.

DT Article
ID FORAGE HARVESTER; COMMERCIAL SWATHER
AB Greater capacity in field experimental research could be achieved by equipment that harvests high-yielding biomass energy crops within small plots. Versatility and cost-effectiveness would be enhanced if the harvester were adaptable to currently available equipment. A narrow-width biomass harvester for experimental plots was constructed to meet these objectives. The machine consists of a hydraulic drive, flail mower, support arm assembly, collection box and weighing platform, and electronic weighing system. The harvester is currently being powered with a 63.7 kW narrow specialty tractor with a 1.4-m outside tread width. The narrow tractor-flail was used to harvest 1.52-m swaths down the centers of 3.8 by 12.2 m plots of switchgrass (Panicum virgatum L.) so that a portion of the crop remained undisturbed for other measurements. The harvester could harvest dry switchgrass yields up to 20 Mg ha(-1) in 8.8-m plots before its collection box was filled. Other grasses and forages with shape and size characteristics similar to switchgrass would also likely be accommodated. Under normal conditions, three people can harvest 12 plots (20 m long) within 1 h including weighing the biomass, emptying the harvester, and bagging samples. The harvester can be attached to a tractor and made ready for harvesting, or removed to make the tractor available for other purposes, in about 1.5 h. Cost of materials for the harvester was <$10,000.

AB Lemongrass [Cymbopogon flexuosus (Steud.) Wats, (syn. Andropogon nardus var. flexuosus Hack; A. flexuosus Nees)] is one of the most widely grown essential oil plants in the world. Field experiments were conducted at Verona and Poplarville, MS, to evaluate the effects of N (0, 40, 80, and 160 kg N/ha) and S (0, 30, 60, and 90 kg S/ha) on lemongrass biomass productivity, essential oil content, yield, and oil composition. Overall, the essential oil content varied within 0.35 to 0.6% of the dried biomass. The major constituents were geranial (25-53%), neral (20-45%), caryophyllene oxide (1.3-7.2%), and t-caryophyllene (0.3-2.2%). Biomass yields at Verona ranged from 9486 to 19,375 kg/ha, while oil yields ranged from 30 to 139 kg/ha. Overall, dry weight yields increased with the application of 80 kg N/ha relative to the 0 kg N/ha and with 160 kg of N/ha relative to the 0 and 40 kg N/ha treatments. At Poplarville, biomass yields varied from 8036 to 12,593 kg/ha, while oil yields ranged from 23.5 to 89.5 kg/ha. The application of N at 160 kg/ha at Poplarville increased dry weight yields relative to the N at 0 or 40 kg/ha rates, irrespective of the rate used for S. At Verona, within each S application rate, biomass yields were highest in Harvest 2, lower in Harvest 1, and the lowest in Harvest 3 (regrowth). The combined biomass yields of Harvest 1 and Harvest 3 would be lower, but oil yields would be higher compared to Harvest 2 (single-harvest system). Lemongrass can be grown as an annual essential oil crop in the southeastern United States, with a potential for dual utilization: essential oil and lignocellulosic material for ethanol production.

AB Rye (Secale cereale L.) is a frequently used winter cover crop in many agronomic production systems in the United States. Our objective was to determine whether incorporating rye into soil while still green results in greater suppression of root-knot nematodes (Meloidogyne spp.) and Palmer amaranth (Amaranthus palmeri S. Wats.) compared to conventional cover crop management. Two similar experiments were conducted: one with peanut (Arachis hypogaea L.) and the other with cotton (Gossypium hirsutum L.). Both experiments were a split-plot design with tillage as the main plot (conventional, green manure, and strip) and cover crop as the subplot. The cover crop treatments were a weedy fallow and the rye cultivars Wrens Abruzzi, Wheeler, Oklon, and Elbon. Wrens Abruzzi produced the greatest amount of biomass, Oklon and Elbon intermediate, and Wheeler the least. Where there was substantial soil disturbance (e. g., conventional tillage and green manure), Palmer amaranth densities were low and not influenced by cover crop. In the strip tillage plots, however, all of the rye cultivars, except Wheeler, reduced establishment of the weed compared to winter fallow. Root galling from nematodes on cotton and peanut was influenced by tillage, but not by rye cover crop. Gall indices on cotton were greater in conventional tillage than in either strip tillage or green manure plots; whereas on peanut, they were greater in the strip tillage than in the conventional tillage or green manure plots. Neither tillage nor cover crop influenced yield except in 2008 in peanut, where yield was lower in strip tillage than in conventional or green manure plots.

AB Conventional plow tillage (CT) is a common soil management practice under irrigated continuous corn (Zea mays L.) in the semiarid central Great Plains that requires a relatively high N fertilizer rate to optimize grain yield and economic returns. This study investigated how four rates of N input (0, 67, 101, and 224 kg N ha(-1)) under irrigated CT management affects aboveground corn production, stover characteristics, and crop biomass. We also examined soil quality parameters under these treatments, including total soil carbon (TSC) and soil particulate organic matter (POM), soil organic carbon (SOC) and total soil nitrogen (TSN) stocks in the 0- to 7.6-, 0- to 15.2-, and 0- to 30.4-cm soil depths of a clay loam soil. Nitrogen fertilization significantly increased corn grain, stalks, cob and stover yields as well as C and N content of the biomass. The C/N ratios of stalks and stover decreased with increasing N rate, but cob C/N ratios did not change. Increasing N rate increased TSN concentration in 0- to 7.6- and 7.6- to 15.2-cm depths and decreased C/N ratio in all soil layers between 1999 and 2008. We found no significant change in SOC and POM-C stocks under increasing N fertilizer addition aft er 10 yr of irrigated, CT continuous corn despite higher stover yields, and the stover C and N returned to the soil aft er harvest with increasing N rate. The lack of increased SOC storage with increasing residue C inputs suggests that decomposition processes controlled the SOC stocks.

TI A Time-Efficient Scooping Method to Prepare Cover Crop Seed for Cone
Planters
SO AGRONOMY JOURNAL
LA English
DT Article
ID EXPERIMENTAL PLOTS; PLANTING ARRANGEMENT; SEGREGATION; GROWTH
AB Cone planters (CP) uniformly distribute seed over research plots; however, preparing seed for CP by weighing is time-consuming. This study evaluated (i) the effect of seed preparation method (scooping with a calibrated cup vs. weighing) on population density of monoculture cover crops planted with a CP, (ii) time required for scooping vs. weighing, and (iii) the effect of scooping on segregation of pre-made cover crop mixtures. Monocultures included mustard [Brassica juncea (L.) Czern.], rye (Secale cereale L.), common vetch (Vicia sativa L.), and faba bean (Vicia faba L.) planted at 1x, 2x, and 4x seeding rates; 1x rates in pure live seed m(-2) were 24 (faba bean), 43 (common vetch), 291 (rye), and 310 (mustard). Mixtures contained rye, oat (Avena sativa L.), barley (Hordeum vulgare L.), faba bean, common vetch, or pea (Pisum sativum L.), and by weight included: Mix 1 (10% rye, 90% faba bean), Mix 2 (10% oat, 90% faba bean), Mix 3 (10% barley, 90% faba bean), Mix 4 (10% common vetch, 90% rye), and Mix 5 (10% rye, 25% pea, 30% common vetch, 35% faba bean). Seed preparation method did not affect the population densities of the monocultures. Preparing seed packets was at least two times more time-consuming with the weighing than scooping method. Calibrating cups to scoop within 1% of the desired seed packet weight was not difficult. However, segregation occurred while scooping some mixtures from a bucket whereby smaller-seeded components increased with scooping depth. Simple methods to detect seed segregation in mixtures are discussed.

TI Tillage and Cattle Grazing Effects on Soil Properties and Grain Yields
in a Dryland Wheat-Sorghum-Fallow Rotation
SO AGRONOMY JOURNAL

ID SOUTHERN HIGH-PLAINS; PLANT WATER STATUS; SYSTEMS; PRODUCTIVITY;
REQUIREMENTS; INFILTRATION; IRRIGATION; NITROGEN; COTTON
AB Cattle (Bos taurus) grazing intensifies production of the dryland wheat (Triticum aestivum L.)-sorghum [Sorghum bicolor (L.) Moench]-fallow (WSF) rotation in the U. S. Southern High Plains. Stubble-mulch (SM) tillage controls weeds and counteracts soil compaction. No-till (NT) increases soil water at planting and dryland crop yields, but added grazing effects are unknown. Our objectives were to quantify dryland winter wheat and sorghum yield responses to grazing and tillage practices. At the USDA-ARS Conservation and Production Research Laboratory, Bushland, TX, we established all WSF rotation phases in triplicate ungrazed and grazed paddocks beginning 1999 on a Pullman clay loam (fine, mixed, superactive, thermic Torrertic Paleustoll) using SM tillage. During spring 2004, NT or SM tillage were superimposed within grazing main plots. Cattle gain, soil water aft er fallow, and crop yield were compared during 2005 to 2009 using a split-plot randomized complete block design. Cattle, stocked at 1.8 Mg ha(-1), grazed sorghum stover and growing wheat an average of 29 d for a mean gain of 147 kg ha(-1). Soil water at planting was unaffected by grazing, but increased from 14 to 28 mm with NT. Although grazing seldom reduced yield of wheat or sorghum, NT in ungrazed plots increased crop yields sufficiently (0.96-2.6 Mg ha(-1)) in 2008 and 2009 to off set any value added by grazing. We conclude that cumulative grazing effects in NT plots reduced soil water storage and depressed yield. We recommend post-wheat-harvest SM tillage to disrupt soil compaction and restore grazed soil productivity.

AB Objective-To compare the toxic effects of a Delphinium occidentale chemotype containing N-(methylsuccinimido) anthranoyllycoctonine (MSAL) type alkaloids and a D occidentale chemotype lacking MSAL-type alkaloids in mice and cattle.
Animals-225 male Swiss Webster mice and 11 Black Angus steers.
Procedures-4 collections of larkspur containing MSAL-type alkaloids and 4 collections of larkspur lacking MSAL-type alkaloids were used. From each collection, total alkaloid extracts (0.05 to 0.20 mL) were administered via tail-vein injection in 27 to 29 mice. Dried, finely ground plant material from 1 collection with and 1 collection without MSAL-type alkaloids (doses equivalent to 376 mg of total alkaloids/kg) were each administered to 8 cattle via oral gavage in a crossover experiment; 3 cattle received a single dose equivalent to 150.4 mg of total alkaloids/kg (no MSAL-type alkaloids). In mice, clinical effects were monitored; in cattle, heart rate was monitored before (baseline) and 24 hours after treatment. At the 24-hour time point, cattle were exercised as a measure of muscle weakness.
Results-In mice, mean LD50 associated with alkaloid extracts prepared from plants that did or did not contain MSAL-type alkaloids was 2.3 and 54.2 mg/kg, respectively. In cattle at 24 hours after treatment, plant material containing MSAL-type alkaloids significantly increased heart rate from baseline and was associated with exercise-induced collapse; plant material lacking MSAL-type alkaloids had no similar effects.
Conclusions and Clinical Relevance-Taxonomic classification of D occidentale alone was not a good indicator of the toxic risk to grazing cattle. (Am J Vet Res 2011;72:706-714)

AB Fluorescence-tagged coniferyl alcohols, coniferyl alcohol gamma-coupled by ethylenediamine spacers to dimethylaminocoumarin or nitrobenzofuran fluorophores, were tested as photoprobes to study the oxidase-mediated polymerization of monolignols. The fluorescent coniferyl alcohol derivatives readily underwent peroxidase-catalyzed in vitro copolymerization with coniferyl alcohol to yield fluorescent dehydrogenation polymers, the backbone polymers of which were structurally indistinguishable from polymers formed solely from coniferyl alcohol. To illustrate the use of the photoprobes, we successfully monitored in real time the complexation of coniferyl alcohol with horseradish apoperoxidase by Forster resonance energy transfer (FRET) using the protein-tryptophan near the active site and a dimethylarninocoumarin moiety as donor and acceptor fluorophores. Furthermore, mixtures of fluorescence-tagged and normal coniferyl alcohols readily diffused into isolated maize cell walls and reacted with wall-bound percoddases to form in muro artificial lignins that could be visualized by fluorescence microscopy. Thus we anticipate that fluorescence-tagged monolignols will be useful for in vitro and in vivo studies of cell wall lignification.

AB Accounting for agroforestry contributions to carbon sequestration and cellulosic feedstock production requires biomass equations that accurately estimate biomass in open-grown trees. Since equations for open-grown trees are rare and developing these is expensive, existing forest-based equations are an attractive alternative for open-grown trees in carbon accounting and biomass modeling. How accurate this alternative is depends on how similar the key attributes, such as specific gravity, trunk shape, and crown architecture, are between open- and forest-grown trees. We evaluated the use of forest-derived specific gravity for conversion of volume to biomass for morphologically distinct open-grown species: green ash, ponderosa pine, and eastern redcedar. Trunk biomass was consistently and significantly underestimated from 6.3% to 16.6% depending on species, indicating open-grown trees have greater trunk specific gravity than forest-grown counterparts within the same geographic region; however a conclusive difference in branch specific gravity was not found between open- and forest-grown trees. Open-grown trees have greater trunk specific gravity, sharper trunk taper, and larger crown. When forest-based equations are used for trunk biomass of open-grown trees, the greater trunk specific gravity results in underestimation; however, the sharper trunk taper results in overestimation. Studies are needed to examine whether the underestimation could be offset by the overestimation and how the larger crown affects biomass estimation when forest-based equations are used for open-grown trees. Our results provide an essential understanding to interpret the biometric relationship of open- to forest-grown trees and to develop an efficient means how forest-based equations might be best modified for open-grown trees.

AB We found that peat moss, amended with various ratios of pellets comprised of equal proportions of biochar and wood flour, generally had chemical and physical properties suitable for service as a substrate during nursery production of plants. High ratios of pellets to peat (> 50%) may be less desirable because of high C:N, high bulk density, swelling associated with water absorption, and low volumetric water content, whereas a mixture of 75% peat and 25% pellets had enhanced hydraulic conductivity and greater water availability at lower (<-10 kPa) matric potentials. Adding pellets to substrates used to grow plants in nurseries has potential to add value to biochar and thereby improve economic viability of pyrolysis. Moreover, biochar-amended substrates offer opportunity to sequester carbon as part of the normal outplanting process. Published by Elsevier Ltd.

AB The objective of this study was to evaluate the performance and to estimate costs of two round baling systems for harvesting understory biomass. One system was a cutter-shredderbaler prototype (Bio-baler). The other system required two successive operations. The first operation was cutting and shredding with a Supertrak tractor equipped with a Fecon mulcher head. The second operation was baling with a Claas baler. The machines were evaluated in three different pine stands on the Osceola National Forest in Florida, United States. Data collection included time study, fuel consumption and bale measurements. Material was collected from a sample of bales for heat and moisture content determination. On the most representative site (Site 2), the Bio-baler recovered 8.05 green t ha(-1) while the mulcher and the Claas baler recovered 9.75 green t ha(-1) (43 and 52 percent of original understory biomass, respectively). Productivity was 0.30 ha h(-1) for the Bio-baler and 0.51 ha h(-1) for the Claas baler. Density of the bales was 321 green kg m(-3) for the Bio-baler and 373 green kg m(-3) for the Claas baler. Average net heat content was 6263 MJ bale(-1) for the Bio-baler and 6695 MJ bale(-1) for the Claas baler with biomass containing 38 percent of moisture content on a wet basis. cost per unit area was less with the Bio-baler (US$320.91 ha(-1)) than with the mulcher-baler system (US$336.62-US$596.77 ha(-1)).

AB Open reading frame 2 (ORF2) of porcine circovirus type 2 (PCV2) codes for the 233-amino-acid capsid protein (CP). Baculovirus-based vaccines that express only ORF2 are protective against clinical disease following experimental challenge or natural infection. The goal of this study was to identify regions in CP preferentially recognized by sera from experimentally infected and vaccinated pigs and to compare these responses to those of pigs diagnosed with porcine circovirus-associated disease (PCVAD), including porcine multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS). The approach was to react porcine sera with CP polypeptide fragments followed by finer mapping studies using overlapping oligopeptides that covered amino acids 141 to 200. The results showed that vaccinated pigs preferentially recognized only the largest polypeptide fragment, CP(43-233). A subset of experimentally infected pigs and pigs with PDNS showed strong reactivity against a CP oligopeptide, 169-STIDYFQPNNKR-180. Alanine scanning identified Y-173, F-174, Q-175, and K-179 as important for antibody recognition. The results from this study support the notion of PCV2 modulation of immunity, including antibody responses that may represent a precursor for disease. The recognition of CP(169-180) and other polypeptides provides opportunities to devise diagnostic tests for monitoring the immunological effectiveness of vaccination.

AB Highest priority zones for tree planting within New York City were selected by using a planting priority index developed combining three main indicators: pollution concentration, population density and low canopy cover. This new tree population was projected through time to estimate potential air quality and carbon benefits. Those trees will likely remove more than 10 000 tons of air pollutants and a maximum of 1500 tons of carbon over the next 100 years given a 4% annual mortality rate. Cumulative carbon storage will be reduced through time as carbon loss through tree mortality outweighs carbon accumulation through tree growth. Model projections are strongly affected by mortality rate whose uncertainties limit estimations accuracy. Increasing mortality rate from 4 to 8% per year produce a significant decrease in the total pollution removal over a 100 year period from 11 000 tons to 3000 tons. (C) 2010 Elsevier Ltd.

AB Salmonella enterica isolates from turkeys in two commercial processing plants (1 and 2) were characterized for susceptibility to antibiotics, disinfectants, and the organoarsenical growth promoter, 4-hydroxy-3-nitrophenylarsonic acid (3-NHPAA, roxarsone), and it's metabolites, NaAsO(2) (As(III)) and Na(2)HAsO(4)center dot 7H(2)O (As(V)). The 130 Salmonella serovars tested demonstrated a low incidence of resistance to the antibiotics gentamicin (GEN), kanamycin (KAN), sulfamethoxazole (SMX), streptomycin (STR), and tetracycline (TET). Isolates resistant to antibiotics were most often multidrug resistant. Serovars Hadar and Typhimurium were resistant to KAN, STR, and TET and GEN, SMX, and STR, respectively. All isolated Salmonella serovars were resistant to the disinfectant chlorhexidine with minimum inhibitory concentrations (MICs; 1-8 mu g/mL), and they were susceptible to triclosan and benzalkonium chloride. The didecyldimethylammonium chloride component was the most active ammonium chloride tested. No cross-resistance was observed between antibiotics and disinfectants. The MICs for 3-NHPAA (4096 mu g/mL) were consistent between processing Plant 1 and Plant 2, but MICs for the 3-NHPAA metabolites (As(III) and As(V)) were higher in Plant 1 than in Plant 2. In Plant 1, 76% of the isolates had MICs > 256 mu g/mL for As(III) and 92% of the isolates had MICs > 1024 mu g/mL for As(V). In Plant 2, all of the isolates had MICs <= 256 mu g/mL for As(III) and 90% of the isolates had MICs <= 1024 mu g/mL for As(V). Only 4 Salmonella serovars were isolated from Plant 1, but 10 serovars were isolated from Plant 2. S. enterica serovar Derby from Plant 1 was highly resistant to As(III) and As(V) with MICs > 1024 and > 8192 mu g/mL, respectively, suggesting previous exposure to high arsenic metabolite concentrations. These levels may have been high enough to kill other Salmonella serovars, thus possibly explaining the lack of serovar diversity observed in Plant 1. The application of a growth promoter may affect the serovar diversity in treated birds.

AB Six Shiga toxin-producing Escherichia coli (STEC) serogroups, which include O26, O45, O103, O111, O121, and O145, are responsible for the majority of non-O157 STEC infections in the United States, representing a growing public health concern. Cattle and other ruminants are reservoirs for these pathogens; thus, food of bovine origin may be a vehicle for infection with non-O157 STEC. Methods for detection of these pathogens in animal reservoirs and in food are needed to determine their prevalence and to develop intervention strategies. This study describes a method for detection of non-O157 STEC in ground beef, consisting of enrichment in modified tryptic soy broth at 42 degrees C, followed by real-time multiplex polymerase chain reaction (PCR) assays targeting stx(1), stx(2), and eae genes and the wzx gene in the O-antigen gene clusters of the six serogroups, and then immunomagnetic separation (IMS) followed by plating onto Rainbow (R) Agar O157 and PCR assays for confirmation of isolates. All ground beef samples artificially inoculated with 1-2 and 10-20 CFU/25 g of ground beef consistently gave positive results for all of the target genes, including the internal amplification control using the multiplex real-time PCR assays after enrichment in modified tryptic soy broth for a total of 24 h (6 h at 37 degrees C and 18 h at 42 degrees C). The detection limit of the real-time multiplex PCR assays was similar to 50 CFU per PCR. IMS for O26, O103, O111, and O145 was performed with commercially available magnetic beads, and the IMS beads for O45 and O121 were prepared using polyclonal antiserum against these serogroups. A large percentage of the presumptive colonies of each serogroup picked from Rainbow Agar O157 were confirmed as the respective serogroups; however, the percent recovery of STEC O111 was somewhat lower than that of the other serogroups. This work provides a method for detection and isolation in ground beef and potentially other foods of non-O157 STEC of major public health concern.

AB Finishing pigs infected with Salmonella pose significant food safety risks by carrying the pathogen into abattoirs. This study was conducted to determine the dynamics of Salmonella infection in finishing pigs, and associated immunological, physiological, and behavioral alterations, by longitudinally comparing infected to noninfected pigs during 6 weeks postinfection (p.i.). Bacteriological data revealed that all inoculated pigs started shedding Salmonella within 2 h p.i., and persistently shed the bacteria up to the end of the study. Ileal and cecal contents, as well as mesenteric lymph node samples, were all positive throughout the study, containing 3-4 log(10) cfu/g of Salmonella at 24 h p.i., and 4-5 log(10) cfu/g of Salmonella up to 4 weeks p.i. Levels of Salmonella dropped markedly (p < 0.05) in all samples at 5 weeks p.i. There was no difference between groups for blood cell counts. Tumor necrosis factor-alpha was greater (p < 0.05) in infected pigs: (1) in the mesenteric lymph nodes by 48 h p.i.; (2) at 24 h and 3 weeks p.i. in the ileum; and (3) in the cecum and spleen at 3 weeks p.i. Interleukin-12, interleukin-1 and its antagonist, and a porcine-specific antimicrobial peptide RNA expression in tissues changed over time, but were not different between groups. Infected pigs spent more time in ventral recumbency, standing, and sitting than controls (p < 0.01). Infected pigs were also more active (p < 0.01), and approached a novel object more quickly than control pigs (p < 0.05). No treatment differences were detected for rectal temperature or plasma cortisol (p > 0.10). This study shows that finishing pigs can carry high levels of Salmonella for up to 4 weeks p.i. in the gastrointestinal contents and mesenteric lymph nodes, shedding high levels of the bacteria without developing clinical symptoms, but developing an immune response throughout the intestinal tract. Moreover, subtle behavioral changes measured as postures were detected, and therefore warrant additional investigation.

ID SOIL; DIVERSITY
AB The surface of beef cattle feedlot pens is commonly conceptualized as being packed uncomposted manure. Despite the important role that the feedlot pen may play in the transmission of veterinary and zoonotic pathogens, the bacterial ecology of feedlot surface material is not well understood. Our present study characterized the bacterial communities of the beef cattle feedlot pen surface material using 3647 full-length 16S rDNA sequences, and we compared the community composition of feedlot pens to the fecal source material. The feedlot surface composite was represented by members of the phylum Actinobacteria (42%), followed by Firmicutes (24%), Bacteroidetes (24%), and Proteobacteria (9%). The feedlot pen surface material bacterial communities were clearly distinct from those of the feces from animals in the same pen. Comparisons with previously published results of feces from the animals in the same pen reveal that, of 139 genera identified, only 25 were present in both habitats. These results indicate that, microbiologically, the feedlot pen surface material is separate and distinct from the fecal source material, suggesting that bacteria that originate in cattle feces face different selection pressures and survival challenges during their tenure in the feedlot pen, as compared to their residence in the gastrointestinal tract.

AB In the present study, we reinvestigate the diversity of Trichoderma in Poland utilizing a combination of morphological and molecular/phylogenetic methods. A total of 170 isolates were collected from six different substrata at 49 sites in Poland. These were divided among 14 taxa as follows: 110 of 170 Trichoderma isolates were identified to the species level by the analysis of their ITS1, ITS2 rDNA sequences as: T. harzianum (43 isolates), T. aggressivum (35), T. citrinoviride (11), T. hamatum (9), T. virens (6), T. longibrachiatum (4), T. polysporum (1), and T. tomentosum (1); 60 isolates belonging to the Viride clade were identified based on a fragment of the translation-elongation factor 1-alpha (tef1) gene as: T. atroviride (20 isolates), T. gamsii (2), T. koningii (17), T. viridescens (13), T. viride (7), and T. koningiopsis (1). Identifications were made using the BLAST interface in TrichOKEY and TrichoBLAST (http://www.isth.info). The most diverse substrata were soil (nine species per 22 isolates) and decaying wood (nine species per 75 isolates). The most abundant species (25%) isolated from all substrata was T. harzianum.

AB Context: IL1b (IL1B or IL1 beta), a key modulator of the immune response, exerts its functions mainly via IL6 regulation. Fatty meals cause transient hypertriglyceridemia and are considered to be proinflammatory, but the extent of these responses shows high interindividual susceptibility.
Objective: We evaluated the influence of a genetic variant located in the promoter region of IL1B (-1473G/C) on fasting and postprandial lipids and IL6.
Design, Setting, and Participants: A total of 477 people over age 65 yr were genotyped for IL1B -1473G/C, and we evaluated fasting lipids depending on genotype. Then, 88 healthy young men were also genotyped and were fed a saturated fatty acid-rich meal. Serial blood samples were drawn for 11 h after the meal, and lipid fractions and IL6 were assayed.
Main Outcome and Interventions: Fasting lipids were studied in the aged persons. Fasting and postprandial measurements of lipids and IL6 were performed in the healthy young men.
Results: In the aged persons, CC subjects (minor allele homozygotes) showed higher triglyceride (P = 0.002) and cholesterol (P = 0.011) levels. Healthy young male carriers of the minor C allele showed higher postprandial triglycerides (P = 0.037), and those carried into large triglyceride-rich lipoproteins (P = 0.004). In addition, they showed higher postprandial IL6 concentrations (P = 0.008).
Conclusions: Our work shows that inflammatory genes may regulate fasting and postprandial lipids because the carriers of the minor allele of an IL gene variant have altered lipid metabolism. To reinforce these gene-phenotype findings, IL6 (the natural effector of IL1B) was increased in these persons. (J Clin Endocrinol Metab 96: E816-E820, 2011)

IMMUNE-RESPONSE; ADIPOSE-TISSUE; ACCUMULATION
AB Obesity is associated with an enhanced inflammatory response that exacerbates insulin resistance and contributes to diabetes, atherosclerosis, and cardiovascular disease. One mechanism accounting for the increased inflammation associated with obesity is activation of the innate immune signaling pathway triggered by TLR4 recognition of saturated fatty acids, an event that is essential for lipid-induced insulin resistance. Using in vitro and in vivo systems to model lipid induction of TLR4-dependent inflammatory events in rodents, we show here that TLR4 is an upstream signaling component required for saturated fatty acid-induced ceramide biosynthesis. This increase in ceramide production was associated with the upregulation of genes driving cerarnide biosynthesis, an event dependent of the activity of the proinflammatory kinase IKKI3. Importantly, increased ceramide production was not required for TLR4-dependent induction of inflammatory cytokines, but it was essential for TLR4-dependent insulin resistance. These findings suggest that sphingolipids such as cerarnide might be key components of the signaling networks that link lipid-induced inflammatory pathways to the antagonism of insulin action that contributes to diabetes.

AB An aqueous dispersion of vital wheat gluten and styrene-butadiene rubber was subjected to high-shear mixing in an attempt to reduce the aggregate size and enhance filler-matrix interactions with the goal of improving contributions of the reinforcement to the overall composite properties. Composites were formulated using 10-40% vital wheat gluten by mixing aqueous suspensions of the gluten and rubber, then freeze-drying and compression molding the resulting composite. Rheological experiments indicated that vital wheat gluten reinforced the rubber up to a factor of roughly 30. Subjecting the gluten suspension to high shearing reduced the particle size from approximately 5.2-4.5 mu m, and 16 min was the optimum shearing time since shearing the dispersions longer did not result in any additional size reduction. Composites with 10% vital wheat gluten have good potential in applications requiring high elasticity since they were equal to or better than the carbon black control in terms of Young's modulus, percent elongation, and toughness. Isolated vital wheat gluten was studied in order to determine its relative merit as one of the two reinforcing components of wheat flour (the other being wheat starch), and vital wheat gluten's reinforcing ability was a factor of 10 weaker than wheat flour, indicating that wheat starch is a much more effective biomaterial filler in terms of rigidity, but vital wheat gluten may be more suitable for applications requiring more elasticity.

AB Since the early 1990's, grapefruit juice has been implicated in drug interaction with various furanocoumarins (FCs) now associated with the effect. Although FCs are present in various fruits and vegetables, it is their presence in grapefruit that has attracted the most attention. Studies have shown that FCs in grapefruit juice can vary significantly and from multiple causes. Most of all, FCs are stress-induced molecules, their levels affected by many factors ranging from UV exposure to insect infestation. There are also varietal and seasonal factors. In this study, juice processing and storage parameters were investigated. Prolonged fruit storage prior to processing and most steps involved in juice processing had little influence on the levels of 6',7'-dihydroxybergamottin (DHB), paradisin C, or bergamottin. However, products that were hot filled or stored at room temperature had lower amounts of DHB and paradisin C and higher amounts of bergaptol compared to juices that were not hot filled and stored at refrigerated temperatures. Both DHB and paradisin C are potent CYP3A4 inhibitors, while bergaptol is a very weak inhibitor. Bergamottin amounts decreased to a lesser extent. Therefore, grapefruit juice products that were hot filled or have been stored at room temperature for an extended period of time will have a reduced drug interaction potential.
Practical Application
This research provides information on how grapefruit drug interaction potential of grapefruit juice products are affected by processing and storage of juice products. Shelf stable products stored at room temperature in cans and glass containers will have lower levels of FCs compared to fresh products made from the same juice. Those wishing to minimize drug interaction potential in grapefruit products may do so by heating to pasteurization temperatures for 30 to 60 min. However, this will only lower and not eliminate the drug interaction potential.

AB Emulsion (EFMO) containing purified menhaden oil (PMO) and soluble rice bran fiber (SRBF) was dried in a pilot scale spray dryer and produced microencapsulated PMO with SRBF (MFMO). EFMO had well isolated spherical droplets with the size of 1 to 10 mu m and showed pseudoplastic fluid and viscoelastic characteristics. EFMO had lower lipid oxidation than the emulsion containing PMO without SRBF when both emulsions were stored at 20 and 40 degrees C for 88 h, which indicated that the SRBF reduced the lipid oxidation in the EFMO. The estimated MFMO production rate (3.45 x 10-5 kg dry solids/s) was higher than the actual production rate (2.31 x 10-5 kg dry solids/s). The energy required to spray dry the EFMO was 12232 kJ/kg of emulsion. EPA and DHA contents of MFMO were 11.52% and 4.51%, respectively. The particle size of 90% MFMO ranged from 8 to 62 mu m, and the volume-length diameter of MFMO was 28.5 mu m.

AB Iron deficiency is a yield-limiting factor with major implications for field crop production in one-third of the world's agricultural areas, especially those with high soil CaCO3. In the present work, a two-dimensional gel electrophoresis proteomic approach was combined with a study on the riboflavin synthesis pathway, including qPCR and riboflavin determination, to investigate Fe-deficiency responses in Medicago truncatula plants grown with and without CaCO3. Iron deficiency caused a de novo accumulation of DMRLs and GTPcII, proteins involved in riboflavin biosynthesis, as well as marked increases in root riboflavin concentrations and in the expression of four genes from the riboflavin biosynthetic pathway. Two novel changes found were the increased accumulation of proteins related to N recycling and protein catabolism. Other identified changes were consistent with previously found increases in glycolysis, TCA. cycle, and stress-related processes. All effects were more marked in the presence of CaCO3. Our results show that the riboflavin biosynthesis pathway was up-regulated at the genomic, proteomic, and metabolomic levels under both Fe-deficiency treatments, especially in the presence of CaCO3. Results also indicate that N recycling occurs in M. truncatula upon Fe deficiency, possibly constituting an additional anaplerotic N and C source for the synthesis of secondary metabolites, carboxylates, and others.

ID HYDROLOGY EXPERIMENT; AMSR-E; VARIABILITY; RETRIEVAL
AB Soil moisture is one of the most important key physical parameters in hydrological and environmental processes. During the past decade, remote sensing measurements have been widely used to provide mean surface soil moisture on a large spatial scale because conventional ground based measurements are not always available and require more time and cost. However, very few studies have been conducted to estimate the potential of remotely sensed soil moisture to correlate with hydrological processes. This study identified that remotely sensed soil moisture data, Advanced Microwave Scanning Radiometer E (AMSR-E), had a reasonable relationship with surface water elevation after statistical scaling. Simple regression models as a function of soil moisture were developed to predict surface water elevation. This study identified the potential of remotely sensed soil moisture to better understand hydrological processes.

AB Mutagenized populations have become indispensable resources for introducing variation and studying gene function in plant genomics research. In this study, fast neutron (FN) radiation was used to induce deletion mutations in the soybean (Glycine max) genome. Approximately 120,000 soybean seeds were exposed to FN radiation doses of up to 32 Gray units to develop over 23,000 independent M2 lines. Here, we demonstrate the utility of this population for phenotypic screening and associated genomic characterization of striking and agronomically important traits. Plant variation was cataloged for seed composition, maturity, morphology, pigmentation, and nodulation traits. Mutants that showed significant increases or decreases in seed protein and oil content across multiple generations and environments were identified. The application of comparative genomic hybridization (CGH) to lesion-induced mutants for deletion mapping was validated on a midoleate x-ray mutant, M23, with a known FAD2-1A (for fatty acid desaturase) gene deletion. Using CGH, a subset of mutants was characterized, revealing deletion regions and candidate genes associated with phenotypes of interest. Exome resequencing and sequencing of PCR products confirmed FN-induced deletions detected by CGH. Beyond characterization of soybean FN mutants, this study demonstrates the utility of CGH, exome sequence capture, and next-generation sequencing approaches for analyses of mutant plant genomes. We present this FN mutant soybean population as a valuable public resource for future genetic screens and functional genomics research.

AB We hypothesized that soybean cyst nematode (SCN; Heterodera glycines) co-opts part or all of one or more innate developmental process in soybean (Glycine max) to establish its feeding structure, syncytium, in soybean roots. The syncytium is formed within the vascular bundle by partial degradation of cell walls and membranes between adjacent parenchyma cells. A mature syncytium incorporates as many as 200 cells into one large multinucleated cell. Gene expression patterns for several cell wall-modifying proteins were compared in multiple tissues undergoing major shifts in cell wall integrity. These included SCN-colonized roots, root tips where vascular differentiation occurs, flooded roots (aerenchyma), adventitious rooting in hypocotyls, and leaf abscission zones. A search in the 5' upstream promoters of these genes identified a motif (SCNbox1: WGCATGTG) common to several genes that were up-regulated in several different tissues. The polygalacturonase 11 promoters (GmPG11a/b) include the SCNbox1 motif. The expression pattern for GmPG11a was examined further in transgenic soybean containing a PG11a promoter fused to a beta-glucuronidase (GUS) reporter gene. GUS expression was highest in cells undergoing radial expansion in the stele and/or cell wall dissolution. GUS staining was not observed in cortical cells where a lateral root tip or a growing nematode emerged through the root cortex.

AB Objective: The proportion of the Latin American population aged >60 years is expected to double during the next few decades. Metabolic syndrome (MetS) is associated with high morbidity and mortality worldwide. However, little is known about MetS in Latin America in general, and in Ecuador in particular. The present study aimed to examine the prevalence of MetS and its association with blood micronutrient, homocysteine (Hcy) and C-reactive protein (CRP) concentrations in the elderly living in a low-income urban area.
Design: We performed a cross-sectional study. MetS, using the International Diabetes Federation definition, dietary intake and plasma micronutrient, CRP and Hcy concentrations were assessed.
Subjects: A total of 352 elderly (>= 65 years) Ecuadorians.
Setting: Quito, Ecuador.
Results: MetS was prevalent (40%) - considerably more so among women (81%) than men (19%; chi(2) = 32.6, P < 0.0001). Further, 53% of those without MetS exhibited two or more of its components. Micronutrient deficiencies were prevalent, including those of vitamin C, zinc, vitamin B(12) and folate. Vitamin C and E concentrations were inversely (OR = 0.78, 95% CI 0.71, 0.86; OR = 0.16, 95% CI 0.03, 0.81, respectively) and CRP (OR =1.79, 95% CI 1.04, 3.06) was positively associated with MetS.
Conclusions: The coexistence of MetS with micronutrient deficiencies suggests that elderly Ecuadorians suffer from the double burden of diseases that are increasingly being observed in less developed countries. More research is needed to determine the causal factors, but results presented suggest that these older adults would benefit from interventions to reduce the risk factors for MetS, in particular higher consumption of micronutrient-rich foods.

AB Proper application management is essential to minimize adverse environmental effects and maximize agronomic benefits of land applying poultry litter as a nutrient source and soil amendment. In this study, turkey (Meleagris gallopavo) litter was applied to five cultivated fields (target rates 4.5, 6.7, 9.0, 11.2, 13.4 Mg ha(-1)) and to two pasture fields (target rates 6.7, 13.4 Mg ha(-1)) to evaluate the effects on surface soil quality in the Vertisol-dominated Texas Blackland Prairie. A cultivated field that received only inorganic fertilizer and two pasture fields (one native prairie and one grazed pasture) served as "controls." Despite the annual variability in litter composition, actual application rates, and weather conditions, 7 years of litter application produced several significant differences in surface soil properties. Litter application produced significant increasing trends in soil organic C and extractable P for several cultivated and pasture fields. Similarly, after seven annual litter applications, litter rate was significantly related to total N, total P, extractable P, Zn, and Cu in the cultivated fields and to total P, extractable P, Zn, and Cu in the pasture fields. These observations coupled with previous findings indicate that annual litter application rates should be within 2.2 to 4.5 Mg ha(-1) for cropland and 4.5 to 6.7 Mg ha(-1) for pasture to limit the buildup of extractable P, Zn, and Cu in the soil. Although these target rates appear to be appropriate, the annual variability in litter composition (both nutrients and moisture) can, if not accounted for, make it difficult to determine proper application rates. Therefore, preapplication soil and litter testing and spreader calibration is strongly recommended so that litter application supplies only crop nutrient requirements (typically P) and balances agronomic and environmental concerns.

AB To rank and better understand the risk of P loss from potentially erodible soil materials in the Mollisol-dominated watershed of Rathbun Lake in southern Iowa, we sampled seven representative soil materials at four floodplain sites. We compared the samples by using a variety of characteristics and indices, including particle size distribution; total P, C, and N; P sorption indices; equilibrium P concentration; and degree of P saturation, as assessed by dithionite, oxalate, and Mehlich 3 extraction (M3) methods. None of the Mehlich 3 P values of samples in the present study were high enough to suggest a high risk of water impairment caused by P. Equilibrium P concentration (EPC) values ranged from 0.01 to 0.23 mg L(-1). We found that EPC values were significantly correlated with Fe extractable by oxalate or the M3, as well as with total C and total N. The oxalate and M3 provided generally consistent degree of phosphorus saturation indices, leading us to propose three general risk categories for these soil materials: low, intermediate, and high. We conclude that poorly crystalline Fe oxides and organic matter are likely to exert considerable control over the release of P to stream water from materials eroded from these sites. Moreover, risk rankings based on degree of phosphorus saturation values may not be consistent with interpretations of P mobility that are derived from EPC and sorption indices.

ID VAPOR-PRESSURES; CHEMICALS; CHEMISTRY; SYSTEM; CROP
AB The environmental fate and toxicity of active ingredients in pesticide formulations has been investigated for many decades, but relatively little research has been conducted on the fate of pesticide co-formulants or inerts. Some co-formulants are volatile organic compounds (VOCs) and can contribute to ground-level ozone pollution. Effective product assessment methods are required to reduce emissions of the most reactive VOCs. Six emulsifiable concentrate pesticide products were characterized for percent VOC by thermogravimetric analysis (TGA) and gas chromatography-mass spectrometry (GC MS). TGA estimates exceeded GC MS by 10-50% in all but one product, indicating that for some products a fraction of active ingredient is released during TGA or that VOC contribution was underestimated by GC MS. VOC profiles were examined using TGA Fourier transform infrared (FTIR) evolved gas analysis and were compared to GC MS results. The TGA FTIR method worked best for products with the simplest and most volatile formulations, but could be developed into an effective product screening tool. An ozone formation potential (OFP) for each product was calculated using the chemical composition from GC MS and published maximum incremental reactivity (MIR) values. OFP values ranged from 0.1 to 3.1 g ozone g(-1) product. A 24-h VOC emission simulation was developed for each product assuming a constant emission rate calculated from an equation relating maximum flux rate to vapor pressure. Results indicate 100% VOC loss for some products within a few hours, while other products containing less volatile components will remain in the field for several days after application. An alternate method to calculate a product OFP was investigated utilizing the fraction of the total mass of each chemical emitted at the end of the 24-h simulation. The ideal assessment approach will include: 1) unambiguous chemical composition information; 2) flexible simulation models to estimate emissions under different management practices; and 3) accurate reactivity predictions.

ID SURFACE; RUNOFF
AB Fluidized gas desulfurization gypsum is a popular agricultural soil amendment used to increase calcium and sulfur contents, and reduce aluminum toxicity. Due to its surface application in conservation tillage systems and high solubility, the soluble components of gypsum may be transferred with agricultural runoff into receiving waters. The current study measured toxicity of gypsum to Ceriodaphnia dubia, Pimephales promelas, Chironomus dilutus, and Hyalella azteca. Solutions at 2,400 mg gypsum/L (maximum solubility) produced no observable toxicity to C. dubia and P. promelas. Mixtures of a control sediment and gypsum indicated no observed toxicity effects for H. azteca, although effects were noted at 25% dilution for C. dilutus. Data suggest gypsum is not harmful to freshwater organisms at concentrations expected in the agricultural environment.

AB This paper compares two methods of measuring the corrosion of steel and galvanized steel in wood: a long-term exposure test in solid wood and a rapid test method where fasteners are electrochemically polarized in extracts of wood treated with six different treatments. For traditional wood preservatives, the electrochemical extract method correlates with solid wood exposure which suggests that the reduction of cupric ions is the cathodic reaction in both the solid wood and the extract. For treatments without copper, the extract method predicted a higher corrosion rate than the solid wood exposure. For these treatments, the cathodic reaction appears to be the reduction of acid and dissolved oxygen. The practical implication of this work is that in some cases, the rapid test method could be used to screen new fasteners and wood preservatives. Scientifically, this work increases the understanding of the mechanism of corrosion of fasteners in treated and untreated wood. Published by Elsevier Ltd.

AB The connection between intestinal microbiota and host physiology is increasingly becoming recognized. The details of this dynamic interaction, however, remain to be explored. Toll-like receptor 2 (Tlr2) is important for its role in bacterial recognition, intestinal inflammation, and obesity-related metabolic changes. Therefore, we sought to determine the epigenomic and metagenomic consequences of Tlr2 deficiency in the colonic mucosa of mice to gain insights into biological pathways that shape the interface between the gut microbiota and the mammalian host. Colonic mucosa from wild type (WT) and Tlr2(-/-) C57BL/6 mice was interrogated by microarrays specific for DNA methylation and gene expression. The mucosal microbiome was studied by next-generation pyrosequencing of bacterial 16S rRNA. The expression of genes involved in immune processes was significantly modified by the absence of Tlr2, a number of which correlated with DNA methylation changes. The epigenomic and transcriptomic modifications associated with alteration in mucosal microbial composition. Several bacterial species, including members of the Firmicutes were significantly different in abundance between WT and Tlr2(-/-) animals. This manuscript highlights the intimate interrelationships between expression of immune-related genes and immunity pathways in the host with compositional and functional differences of the mammalian microbiome.-Kellermayer, R., Dowd, S.

AB WindSat has provided an opportunity to investigate the first spaceborne passive fully polarimetric observations of the Earth's surface. In this paper, Arctic sea ice was investigated. The passive polarimetric data are provided in the form of the modified Stokes vector consisting of four parameters. The first two components of the modified Stokes vector are the vertically and horizontally polarized brightness temperatures, which have been continuously measured by various radiometers over the last three decades. The third and fourth Stokes components provide information on the degree of polarization of the emission. In this paper, three types of analysis are carried out: spatial (maps considering different azimuth angle intervals), temporal (time series of daily averaged Stokes components over a small selected azimuth angle range), and azimuthal (variations w.r.t. the azimuth angle over selected study areas). Analysis has shown the highest brightness temperature variations for the 37-GHz third Stokes component (> 2 K) during summer. The next highest signals were observed for the 10.7-GHz third and fourth Stokes components (> 1 K) during summer as well. The 37-GHz fourth Stokes component exhibited the least variability (> 1 K). Spikes of up to 2 K were identified in the time series of the 37-GHz third Stokes component during mid-January 2004 (winter) over first-year ice regions. The near-surface air temperature of the European Center for Medium-Range Weather Forecasts model data and the Special Sensor Microwave/Imager National Aeronautics and Space Administration Team ice concentrations revealed that, during these events, the surface temperatures reached near melting levels and the retrieved ice concentrations were reduced to about 80%. Moreover, these observations also showed clear evidence of first harmonic azimuthal dependence. Geophysical parameters, such as temperature and ice leads, are likely to be the causes. The larger signals which occurred during summer were identified as being related to the ice surface temperatures being near melting.

AB The fatty acid composition, Acid Value, and the content and composition of tocopherols, tocotrienols, carotenoids, phytosterols, and steryl ferulates were determined in corn germ oil and four post-fermentation corn oils from the ethanol dry grind process. The oxidative stability index at 110 degrees C was determined for the five oils, and four oils were compared for their stability during storage at 40 degrees C as determined by peroxide value and hexanal content. The fatty acid composition of all five oils was typical for corn oil. The Acid Value (and percentage of free fatty acids) was highest (28.3 mg KOH/g oil) in corn oil extracted centrifugally from a conventional dry grind ethanol processing facility and for oil extracted, using hexane. from distillers dried grains with solubles (DOGS) from a raw starch ethanol processing facility (20.8 mg KOH/g oil). Acid Value was lowest in two oils extracted centrifugally from thin stillage in a raw starch ethanol facility (5.7 and 6.9 mg KOH/g oil). Tocopherols were highest in corn germ oil (similar to 1400 mu g/g), but tocotrienols, phytosterols, steryl ferulates, and carotenoids were higher in all of the post-fermentation corn oils. Hexane extracted oil from DDGS was the most oxidatively stable as evaluated by OSI and storage test at 40 degrees C, followed by centrifugally extracted thin stillage oil from the raw starch ethanol process, and centrifugally extracted thin stillage oil from the conventional dry grind ethanol process. Corn germ oil was the least oxidatively stable. When stored at room temperature, the peroxide value of centrifugally extracted thin stillage oil from the raw starch ethanol process did not significantly increase until after six weeks of storage, and was less than 2.0 mequiv. peroxide/kg oil after three months of storage. These results indicate that post-fermentation corn oils have higher content of valuable functional lipids than corn germ oil. Some of these functional lipids have antioxidant activity which increases the oxidative stability of the post-fermentation oils. Published by Elsevier B.V.

AB Podophyllotoxin is a precursor for compounds used in the synthesis of commercially available anticancer drugs and their precursors etoposide, teniposide, and etopophos. Podophyllotoxin is currently obtained from the underground plant parts (roots and rhizomes) of Himalayan mayapple (Podophyllum emodii Wall.) but is also found in several other species, including American mayapple. There is no information in the literature on podophyllotoxin concentration in the roots or rhizomes of the American mayapple, and it was not clear if podophyllotoxin concentration in underground plant parts is correlated with the concentration in aboveground plant parts. The objective of this study was to estimate podophyllotoxin concentration in the leaves and rhizomes of 28 accessions of American mayapple under natural conditions (wild) and compare this to podophyllotoxin concentrations of same accessions in the leaves when cultivated. Podophyllotoxin concentration in the rhizomes was positively correlated to soil organic matter content and to the concentrations of soil-available P and Na. Podophyllotoxin in the leaves was negatively correlated to soil-available Mg concentrations. The concentration of podophyllotoxin in the leaves varied from undetectable amounts to 2.52%, whereas podophyllotoxin in rhizomes varied from 0.14% to 0.42%. Most of the accessions had greater than 0.45% podophyllotoxin concentration in the leaves under both wild and cultivated conditions. There was no significant correlation between the podophyllotoxin concentrations in rhizomes and leaves; nine accessions had the highest podophyllotoxin concentration in leaves under natural environment. Another nine accessions had the highest podophyllotoxin in the leaves under cultivated conditions, and an additional eight accessions had greater podophyllotoxin concentrations in roots than in leaves irrespective of the environment. The results from this study may contribute toward developing American mayapple into a new cash crop for U.S. farmers. (C) 2011 Published by Elsevier B.V.

AB Dry common beans (Phaseolus vulgaris L) were evaluated for potential conversion of starch to ethanol. Eight varieties of beans with average starch content of 46% (db) were assayed in a laboratory-scaled process based upon the commercial corn dry grind fermentation process. Ethanol yield was 0.43-0.51 g ethanol/g glucose (0.19-0.23 g ethanol/g beans). The average ethanol yield for the eight bean types was 92% of maximum theoretical yield, demonstrating that starch from beans could be efficiently converted to ethanol. Ethanol concentration obtained from 20% (w/w) solids loading was 3.5-4.4% (w/v). The residual fermentation solids contained, on a dry basis, 37.1-43.6% crude protein, 10.8-15.1% acid detergent fiber and 19.1-31.3% neutral detergent fiber. Published by Elsevier B.V.

AB The objective is to evaluate the effect of oxalic acid (OA) and steam-pretreatment on the primary performance of rice straw particleboards. In addition, the effect of various treatment conditions on carbohydrates released from rice straw particles was investigated. The results show that steam- and short durations of OA-treatment significantly improved the mechanical properties and dimensional stability of rice straw particleboards. However, steam-treated rice straw (without OA-treatment) panels exhibited even better performance when compared with OA-treated panels. OA-pretreatment time has a negative effect on performance of panels, whereas the effect of temperature on the performance of OA-treated panels was not significant, except for the linear expansion. OA-treatment accelerated carbohydrates extraction. The sugars released from the OA-treated rice straw particles increase with increasing treatment temperature and time. Carbohydrates extracted from rice straw particles could be a potential sustainable resource for biofuel or bio-based chemicals. (C) 2011 Published by Elsevier B.V.

AB This study was conducted to evaluate the suitability of using residual plant fibers from agricultural waste streams as reinforcement in thermoplastic composites. Three groups of plant fibers evaluated included cotton burrs, sticks and linters from cotton gin waste (CGW), guayule whole plant, and guayule bagasse. The plant fibers were characterized for physical (bulk density and particle size distribution) and chemical properties (ash, lignin and cellulose contents). A laboratory experiment was designed with five fiber filler treatments, namely control (oak wood fiber as the filler - OWF), cotton burr and sticks (CBS), CBS with 2% (by weight) second cut linters (CBL). CBS with 30% (by weight) guayule whole plant (CGP), and CBS with 30% (by weight) guayule bagasse (CGB). The composite samples were manufactured with 50% of fiber filler, 40% of virgin high-density polyethylene (HDPE), and 10% other additives by weight. The samples were extruded to approximately 32 x 7 mm cross-sectional profiles, and tested for physico-mechanical properties. The CBS and CBL had considerably lower bulk density than the other fibers. Cotton linters had the highest alpha-cellulose (66.6%), and lowest hemicellulose (15.8%) and lignin (10.5%) of all fibers tested. Guayule whole plant had the lowest alpha-cellulose and highest ash content. Both CBS and guayule bagasse contained alpha-cellulose comparable to OWF, but slightly lower hemicellulose. Evaluation of composite samples made from the five fiber treatments indicated that fibers from cotton gin byproducts and guayule byproducts reduced the specific gravity of the composites significantly. However, the CBS and CBL samples exhibited high water absorption and thickness swelling, but the addition of guayule bagasse reduced both properties to similar levels as the wood fiber. The CGP exhibited significantly lower coefficient of thermal expansion. Composite samples with the five different fiber fillers showed similar hardness and nail holding capacity, yet oak fibers imparted superior strength and modulus under flexure and compression with the exception of the compressive modulus of CGB composites. In general, both cotton ginning and guayule processing byproducts hold great potential as fiber fillers in thermoplastic composites. (c) 2011 Elsevier B.V. All rights reserved.
