The AOAC Official Methods (944.12,960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the fortification regulations were finalized, no Official AOAC or Approved AACC methods for folate in cereal-grain products were in place. The AOAC Official Method (992.05) for folic acid in infant formula does not incorporate important improvements in the extraction procedure and was not considered suitable for the analysis of folates in foods in general. A microbiological assay protocol using a trienzyme extraction procedure was prepared and submitted for comments to 40 laboratories with recognized experience in folate analysis. On the basis of comments, the method was revised to have the conjugase (gamma-glutamyl-carboxy-peptidase) treatment follow a protease treatment, to include the use of cryoprotected inoculum, and to include the spectroscopic standardization of the standard and optional use of microtiter plates. Thirteen laboratories participated in a collaborative study of 10 required and 10 optional cereal.-grain products, including flour, bread, cookies, baking mixes, and ready-to-eat breakfast cereals. The majority of the participating laboratories performed the assay by the standard test tube method; others used the microtiter plate modification for endpoint quantitation with equal success. For the required products, the relative standard deviation between laboratories (RSDR) ranged from 7.4 to 21.6% for 8 fortified (or enriched) products compared with expected (Horwitz equation-based) values of 11-20%. RSDR values were higher (22.7-52.9%) for 2 unfortified cereal-grain products. For the optional products, the RSDR ranged from 1.8 to 11.2% for 8 fortified products. RSDR values were higher (27.9-28.7%) for 2 unfortified cereal-grain products. Based on the results of the collaborative study, the microbiological assay with trienzyme extraction is recommended for adoption as Official First Action.

The determination of peanut proteins in foods by analytical methods can reduce the risk of serious reactions in the highly sensitized individual by allowing for the detection of these proteins in a food at various stages of the manufacturing process. The method performance of 4 commercially available enzyme-linked immunosorbent assay (ELISA) kits was evaluated for the detection of peanut proteins in milk chocolate, ice cream, cookies, and breakfast cereals: ELISA-TEK Peanut Protein Assay, now known as "Bio-Kit" for peanut proteins, from ELISA Technologies Inc.; Veratox for Peanut Allergens from Neogen Corp.; RIDASCREEN Peanut Kit from R-Biopharm GmbH; and ProLisa from Canadian Food Technology Ltd. The 4 test kits were evaluated for accuracy (recovery) and precision using known concentrations of peanut or peanut proteins in the 4 food matrixes. Two different techniques, incurred and spiked, were used to prepare samples with 4 known concentrations of peanut protein. Defatted peanut flour was added in the incurred samples, and water-soluble peanut proteins were added in the spiked samples. The incurred levels were 0.0, 10, 20, and 100 mug whole peanut per g food; the spiked levels were 0.0, 5, 10, and 20 mug peanut protein per g food. Performance varied by test kit, protein concentration, and food matrix. The Veratox kit had the best accuracy or lowest percent difference between measured and incurred levels of 15.7% when averaged across all incurred levels and food matrixes. Recoveries associated with the Veratox kit varied from 93 to 115% for all food matrixes except cookies. Recoveries for all kits were about 50% for cookies. The analytical precision, as measured by the variance, increased with an increase in protein concentration. However, the coefficient of variation (CV) was stable across the 4 incurred protein levels and was 7.0% when averaged across the 4 food matrixes and analytical kits. The R-Biopharm test kit had the best precision or a CV of 4.2% when averaged across all incurred levels and food matrixes. Because measured protein values varied by test kit and food matrix, a method was developed to normalize or transform measured protein concentrations to an adjusted protein value that was equal to the known protein concentration. The normalization method adjusts measured protein values to equal the true protein value regardless of the type test kit or type food matrix.

The purpose of this study was to determine whether adult bees with the SMR trait affect mites in brood after cells are capped. Colonies with or without the SMR trait were each given a comb of newly-capped worker brood that was naturally infested with varroa. Each of 7 source colonies provided a comb of brood to at least one SMR (n = 9) and one control colony (n = 8). These combs were removed from their host colonies 8 days later and mite populations evaluated in cells with bee pupae that were > 8 days post-capping. Colonies with SMR bees averaged 2.2% of their cells infested with mites; controls averaged 9.0%. Therefore, bees with the SMR trait apparently removed mites from capped cells. Of the mites that remained, the SMR colonies had a much lower rate of reproductive mites, 20% vs. 71%. This suggests that bees with the SMR trait removed reproductive mites more often than they removed non-reproductive mites. When comparing only the number of mites that produced no progeny, the groups were almost identical averaging 1.2 and 1.3 mites per 100 cells of brood. This suggests that the SMR bees did not remove mites from brood cells if the mites did not lay eggs. By targeting the reproductive mites, bees with the SMR trait give the illusion that nearly all of the mites are non-reproductive. Therefore, our selection for a low frequency of reproductive mites may have produced bees that remove reproductive mites from capped brood.

All compounds but one are currently approved by the US Food and Drug Administration for agricultural uses. The most active approved antibiotics screened were pirlimycin, tiamulin, and the polyether ionophores, particularly narasin, lasalocid, salinomycin, laidlomycin, and maduramicin. Pirlimycin and tiamulin show high activity in vitro, but share the mode of action of tylosin and lincomycin (inhibition of ribosomal peptide synthesis), and therefore have no advantage over it. While the ionophores have high in vitro activity and a completely different mode of action (interference with cation transport across cell membranes) and therefore seemed to represent potential alternative treatments for AFB, they were inactive in the field.

As a supplement to morphological identification, we developed a simple PCR-based method for selected Ascosphaera species. We exploited sequence differences in the internal transcribed spacer regions of rDNA to design species-specific primers. Analysis involves simply scoring the presence or absence of a single band for a given pair of primers. The method can distinguish the four Ascosphaera species known to be associated with honey bees. It also distinguishes Ascosphaera aggregata, the chalkbrood pathogen of the alfalfa leafcutting bee, from other Ascosphaera species associated with this bee. We expect the method will be useful for determining purity of Ascosphaera cultures, and may be a first step toward development of an early detection method of chalkbrood infection in honey bees and leafcutting bees. We also present a new, quick and reliable method for preparing fungal DNA suitable for PCR amplification from mycelia grown in liquid or on solid media.

Two dosages (100 or 200 mg) of tylosin tartrate or lincomycin hydrochloride were evaluated. Each antibiotic was applied in 20 g of confectioner's sugar three times at 7-day intervals. The higher dosage of both antibiotics gave consistent control after 45 days. The lower dose of 100 mg did not result in complete control in the colonies treated with tylosin; one of the 10 colonies still had detectable disease after 45 days. Thus, a dose of 200 mg applied three times over three weeks in dust form was highly effective in controlling American foulbrood and represents an appropriate dose for either of these antibiotics.

We compared vertical versus horizontal displacements of a nest block in the first experiment and of a proximal landmark in the second experiment. In a third experiment, we removed either vertical or horizontal proximal landmarks. Bees responded to changes applied to the nesting area by increasing nest location time and displaying behaviours consistent with confusion (hovering flights, reorientation flights, wrong nest visitations). The nest block displacements revealed a higher level of disorientation with horizontal displacements than with vertical displacements. Proximal landmark displacements led to disorientation with a horizontal displacement, but not with a vertical displacement. Removing proximal landmarks elicited disorientation, regardless of the orientation of the remaining landmarks. C1 Utah State Univ, Dept Biol, Logan, UT 84322 USA.

In the past, most work has used cell counting chambers and small repeated samples to assess the number of sperm stored in a queen's spermatheca. To calibrate a spectrophotometer to measure sperm concentration using the entire contents of the spermatheca, five groups of queens - virgins, naturally mated, or inseminated with one, four or eight mu l of semen - were assayed. Absorbance at 260 nm and 550 nm gave measures that were significantly correlated with direct cell counts using a counting chamber. Although the viability (percentage of live sperm) was high for semen stored at room temperature for eight weeks, a second population of queens inseminated with semen stored for four weeks or longer had reduced concentrations of sperm in the spermatheca. The area and quality (drones in worker cells) of brood from queens inseminated with fresh and two-week old semen were similar, but there was a trend toward reduced brood area and increased drone laying in queens receiving semen stored over four weeks.

Here, pairwise inhibition assays were used to identify honey bee bacterial symbionts that inhibit a primary pathogen, the Gram-positive bacterium Paenibacillus larvae larvae. Four bacterial taxa isolated from bee larvae appeared especially promising with respect to inhibition of P.I. larvae and, in fact, completely inhibited P L larvae growth in pairwise plate assays. These isolates were identified by 16S ribosomal RNA sequencing as Stenotrophomonas maltophilia, Acinetobacter sp., Brevibacillus formosus and Bacillus fusiformis. A PCR-based survey confirmed that these bacterial isolates are present in bee larvae, at frequencies ranging from 2% (1/48) for B. formosus to 79% (39/48) for Acinetobacter sp. An understanding of the distributions of these co-occurring bacteria could elucidate variation across colonies in susceptibility to American foulbrood disease. In addition, supplementation of colonies with these naturally occurring bacteria or their antagonistic products can provide a novel way of controlling foulbrood disease.

Methods and Results: Isolates were tested for antimicrobial susceptibility using the E-test method. Approximately 60% (n = 267) were resistant to one or more antimicrobials, and 19.6% (n = 88) were resistant to two or more antimicrobials. Of the Campylobacter jejuni isolates, 49.1% (n = 187) were resistant to tetracycline, 10.2% (n = 39) were resistant to nalidixic acid, 8.4% were resistant to trimethoprim/sulfamethoxazole, and 1.8% (n = 7) were resistant to ciprofloxacin. Resistance to any of the other eight antimicrobials was 1.3% or less, but 14.4% (n = 55) were resistant to two or more antimicrobials. In the Campylobacter coli group, 65.7% (n = 44) were resistant to tetracycline, 52.2% (n = 35) were resistant to trimethoprim/sulfamethoxazole, 22.4% (n = 15) were resistant to nalidixic acid, and 9.0% (n = 6) were resistant to ciprofloxacin. Resistance to any of the remaining eight antimicrobials was 3.0% or less, although 49.3% (n = 33) were resistant to two or more antimicrobials. Conclusions: Although antimicrobials are widely used in US feedlot cattle production, our results demonstrate generally low levels of resistance to a broad range of commonly used antimicrobials relative to other recent studies. Significance and Impact of the Study: Resistance data on Campylobacter isolated from this major US livestock commodity is lacking. This overview enhances current knowledge and provides a basis for further studies. C1 USDA ARS, Bacterial Epidemiol & Antimicrobial Resistance Re, Richard B Russell Agr Res Ctr, Athens, GA 30605 USA.

Methods and Results: Animals were fed over three dietary phases to match production needs from age 10-14 weeks, 14-18 weeks and 18-22 weeks. For each feeding phase, diets were formulated to contain 0 or 10% DSM (balanced for metabolizable energy and true ileal digestible amino acids). Animals were weighed every 2 weeks and faecal samples were collected from 40 animals (20 with DSM and 20 without DSM) at week 10 (d 0 on diets), 14, 18 and 22 of age, and were analysed for Lactobacillus spp., Enterobacteriaceae, coliforms, E. coli, Salmonella, Campylobacter and E. coli O157:H7. At the start of the study (week 10), faecal bacterial counts (log(10) CFU g(-1) faeces) were 9.55, 7.26, 7.01 and 6.93 for Lactobacillus, Enterobacteriaceae, coliforms and E. coli populations respectively. The Enterobacteriaceae, coliform and E. coli populations decreased through week 14 and 18, but were higher in animals fed with the DSM diet compared with the basal diet without DSM. The Lactobacillus populations at weeks 14 and 18 were lower in the animals fed the diet without DSM, whereas feeding DSM maintained the Lactobacillus counts from week 10. At week 22, populations of Enterobacteriaceae, coliforms and E. coli were > week 18 for the animals fed the diet without DSM, less change was observed with the feeding of DSM, and no differences between the diets were observed at week 22. However, in week 22 the animal gain was positively correlated with Lactobacillus numbers and negatively correlated with E. coli numbers. Subtraction of the E. coli population (log(10)) from the Lactobacillus population (log(10)) yielded a positive value termed 'effective'Lactobacillus that correlated well with animal gain and may better define a beneficial function in the intestine. Salmonella were detected in over 60% of the animals at week 10 and 14, and < 20% at week 18 and 22. Campylobacter were detected rarely at weeks 10, 14 and 18, but were found in 25% of the animals at week 22. The DSM did not affect Salmonella or Campylobacter shedding, but examination of individual animals over the entire experiment indicated that fewer recurring incidences of Salmonella shedding occurred in animals that maintained higher Lactobacillus. In addition, at week 22, Salmonella and Campylobacter shedding was associated with lower levels of effective Lactobacillus and lower animal weight gains. Conclusions: The DSM did not directly affect the animal performance or pathogen shedding via the Lactobacillus spp. population at any phase of production. However, analysis of data from all animals revealed that faecal Lactobacillus affected Salmonella shedding and in the finishing phase, animal growth and pathogen shedding also were affected, as reflected by the 'effective'Lactobacillus-associated observations. Significance and Impact of the Study: In the swine intestine, any benefits from gastrointestinal Lactobacillus may be compromized by the E. coli population, and this antagonism may explain responses observed with prebiotics or probiotics in some swine.

Methods and Results: Sequencing was on fosmid clones selected by homology to Aspergillus parasiticus sequence. Alignments revealed that gene order is conserved among AF gene clusters of Aspergillus nomius, A. parasiticus, two sclerotial morphotypes of Aspergillus flavus, and an unnamed Aspergillus sp. Phylogenetic relationships were established using the maximum likelihood method implemented in PAUP. Based on the Eurotiomycete/ Sordariomycete divergence time, the A. flavus-type cluster has been maintained for at least 25 million years. Such conservation of the genes and gene order reflects strong selective constraints on rearrangement. Phylogenetic comparison of individual genes in the cluster indicated that ver-1, which has homology to a melanin blosynthesis gene, experienced selective forces distinct from the other pathway genes. Sequences upstream of the polyketide synthase-encoding gene vary among the species, but a four-gene sugar utilization cluster at the distal end is conserved, indicating a functional relationship between the two adjacent clusters. Conclusions: The high conservation of cluster components needed for AF production suggests there is an adaptive value for AFs in character-shaping niches important to those taxa. Significance and Impact of the Study: This is the first comparison of the complete nucleotide sequences of gene clusters harbouring the AF blosynthesis genes of the main AF-producing species. Such a comparison will aid in understanding how AF biosynthesis is regulated in experimental and natural environments. C1 USDA, ARS, SRRC, New Orleans, LA 70179 USA.

Methods and Results: The 16S-23S rRNA spacer regions of 19 Edw. ictaluri and four Edw. tarda isolates from four geographical regions were amplified by PCR with primers complementary to conserved sequences within the flanking 16S-23S rRNA coding sequences. Two products were generated from all isolates, without interspecies or intraspecific size polymorphisms. Sequence analysis of the amplified fragments revealed a smaller ISR of 350 bp, G Ala which contained a gene for tRNA(Glu), and a larger ISR of 441 bp, which contained genes for tRNA(Ile) and tRNA The sequences of the smaller ISR of different Edw. ictaluri isolates were essentially identical to each other. Partial sequences of larger ISR from several Edw. ictaluri isolates also revealed no differences from the one complete Edw. ictaluri large ISR sequence obtained. The sequences of the smaller ISR of Edw. tarda were 97% identical to the Edw. ictaluri smaller ISR and the larger ISR were 96-98% identical to the Edw. ictaluri larger ISR sequence. The Edw. tarda isolates displayed limited ISR sequence heterogeneity, with >= 97% sequence identity among isolates for both small and large ISR. Conclusions: There is a high degree of size and sequence similarity of 16S-23S ISR both among isolates within Edw. ictaluri and Edw. tarda species and between the two species. Significance and Impact of the Study: Our results confirm a close genetic relationship between Edw. ictaluri and Edw. tarda and the relative homogeneity of Edw. ictaluri isolates compared with Edw. tarda isolates. Because no differences were found in ISR sequences among Edw. ictaluri isolates, sequence analysis of the ISR will not be useful to distinguish isolates of Edw. ictaluri. However, we identified restriction sites that differ between ISR sequences of Edw. ictaluri and Edw. tarda, which will be useful in distinguishing the two species.

Methods and Results: Samples taken from circulated and stagnant wastewater lagoons, over a 1-year period, were analysed for 10 chemical (total N, NH3, NO3, NO2, Na, Ca, HCO3, Fe, P and K) and six physical (biological oxygen demand, chemical oxygen demand, dissolved solids, electrical conductivity, pH and sodium absorption ratio) parameters and were found to be similar. The 16S rDNA genes from the samples were amplified, cloned and BLAST analysed. In total, 996 stagnant and 1052 circulated wastewater derived sequences were obtained, comprising 294 and 362 operational taxonomic units (OTUs) from the circulated and stagnant wastewaters respectively. Coverage estimates of the OTUs identified were 72.1% for the stagnant, and 63.6% for the circulated wastewater libraries. The greatest difference between the two wastewaters was a c. sixfold greater number of sequences representative of the family Chromatiaceae in the circulated wastewater derived library and a c. fivefold greater number of sequences representative of the phylum Chloroflexi in the stagnant wastewater derived library. Conclusions: Circulation of dairy wastewater does not affect any of the chemical or physical parameters tested; however, circulation does alter the bacterial community structure. Significance and Impact of the Study: This study provides evidence that circulation of dairy wastewater promotes the growth of bacteria within the family Chromatiaceae and that stagnant systems promote the growth of the phylum Chloroflexi.

Methods and Results: All chickens were challenged with seven fluoroquinolone sensitive Campylobacter jejuni ( 6.6 x 10(6) CFU per bird) at 2 weeks posthatch. At 26 days of age chickens were treated with 0 ( n = 29 birds), 25 mg ml(-1) enrofloxacin ( Baytril (R), Bayer Corp., Shawnee Mission, KS, USA) for 3 days ( n 45 birds) or 50 mg ml(-1) enrofloxacin for 7 days ( n 65 birds) in the drinking water. The crop, upper ileum, lower ileum, ceca and colon contents were collected from both enrofloxacin treatment groups ( n 5 birds per day per treatment group) and nonmedicated controls. The minimum inhibitory concentration ( MIC) of ciprofloxacin for Campylobacter increased for isolates from both treatment groups within the first day of dosing and the daily average ranged from 1.4 to 6.5 mu g ml(-1) throughout the study. Although enteric fluoroquinolone concentrations were higher ( P < 0.05) in birds dosed with 50 mg ml(-1) vs 25 mg ml) 1 enrofloxacin, there were no differences between the isolates collected from these groups for MIC values. Conclusion: These data indicate, for the doses used, differences in gut fluoroquinolone concentrations do not produce isolates of Campylobacter with differing susceptibility to ciprofloxacin. Significance and Impact of the Study: Using the manufacturers lowest, shortest duration dose vs the highest, longest duration dose of enrofloxacin did not change Campylobacter susceptibility to ciprofloxacin. However, ciprofloxacin MIC values for Campylobacter determined in this study were lower than previously reported. C1 Univ Arkansas, Dept Poultry Sci, Fayetteville, AR 72701 USA.

However, compared with control animals, a greater percentage of PTU-treated cattle ejected E. coli O157:H7 on day 16 (100 vs 25%) and 18 (75 vs 0%) of the post-treatment period. Serum T-3 was lower in PTU-treated cattle during the 14-day treatment period and greater on day 18 of the post-treatment period. Conclusion: Cattle with chemically altered thyroid hormones had similar shedding patterns of faecal E. coli O157:H7 and EC during the 14-day treatment period. However, faecal shedding of E. coli O157:H7 tended to be greater, and serum concentrations of T-3, were greater for PTU-treated cattle immediately following the termination of PTU treatment. Significance and Impact of the Study: Short-term chemical inhibition of thyroid hormones had minimal effects on faecal shedding of E. coli O157:H7 in naturally infected cattle. However, a hyperthyroid state as observed postdosing might play a role in the seasonal shedding of E. coli O157:H7 in cattle. C1 USDA ARS, So Plains Agr Res Ctr, College Stn, TX 77845 USA.

Methods and Results: Standard polymerase chain reaction (PCR), using an oligonucleotide sequence, designated TEC1, was shown, in combination with a previously developed primer (LD2) to amplify strains of B. burgdorferi sensu stricto, Borrelia afzelii, and Borrelia garinii, but not the non-Lyme causing B. hermsii or B. turicatae. This primer pair, designated Bbsl, was successfully used to amplify B. burgdorferi sensu lato from skin biopsies of patients with Lyme disease symptoms as well as from Ixodes scapularis, Amblyomma americanum and Dermacentor variabilis ticks. Conclusions: The primer set Bbsl allows for the rapid detection and differentiation of B. burgdorferi sensu lato from non-Lyme disease-causing Borrelia species in ticks and human tissues. Significance and Impact of the Study: The PCR primer set, Bbsl, will greatly facilitate detection of the causative agents of Lyme disease in infected ticks and human skin samples assisting in epidemiological studies, and potentially allowing for a more rapid diagnosis of the disease in patients.

Rapid response actions included containment under pvc tarps coupled with injection of liquid sodium hypochlorite. To assess the efficacy of these treatments, replicated sediment cores were removed from representative treated sites and transferred to grow-out facilities. Similar cores from uninfested (control) sediments were removed, inoculated with viable explants of C. taxifolia and placed in grow-out facilities. Results from two sampling periods (1 year, 2 years post-treatment) showed that no viable C. taxifolia emerged in cores, and that inoculated "control" sediments supported normal growth. Eelgrass (Zostera marina L.) seedlings emerged from native seed-banks in "treated" cores, which also supported growth of some invertebrates (annelid worms and hydroids). This study provided essential verification of C. taxifolia eradication efforts, and demonstrates the feasibility of incorporating quality control/quality assurance components in rapid response actions. Results of this study also suggest that seeds of eelgrass are viable for at least two years. C1 USDA ARS, Exot & Invasive Weed Res Lab, Davis, CA 95616 USA. Merkel & Assoc Inc, San Diego, CA USA.

Seed viability was determined over different burial durations in the soil through a combination of germination tests and 2,3,5-triphenyl-tetrazolium chloride (TTC) treatments. Control seeds kept dry at 25 C in the laboratory maintained same viability of ca. 15% over the 3-year study. In the field, seed viability decreased with increased burial duration. Most buried seeds lost viability by ca. 1.5 year at seasonally flooded and permanently flooded sites, whereas seeds buried at non-flooded sites survived over a period up to 2 to 2.3 years. Burial depth increased seed viability at the non-flooded sites (P < 0.0001), but had little effect on viability at seasonally (P = 0.3691) and permanently flooded sites (P = 0.0735). Soil types also had significant effect on seed viability. Seeds buried in organic (muck) soils decreased viability significantly faster (P < 0.0001) than those in sandy loam soils. Our results suggest that it may be possible to greatly reduce soil seed populations of Melaleuca in south Florida within 2 to 3 years after the seed source is eliminated.

Pellicle formation behavior requires production of extracellular polysaccharide, cellulose, and protein filaments, known as curli. Protein filaments analogous to curli are formed by many protein secretion systems, including the type III secretion system (TTSS). Here, we demonstrate that Erwinia chrysanthemi, which does not carry curli genes, requires the TTSS for pellicle formation. These data support a model where cellulose and generic protein filaments, which consist of either curli or TTSS-secreted proteins, are required for enterobacterial aggregative multicellular behavior. Using this assay, we found that hrpY, which encodes a two-component system response regulator homolog, is required for activity of hrpS, which encodes a sigma(54)-dependent enhancer-binding protein homolog. In turn, hrpS is required for activity of the sigma factor homolog hrpL, which activates genes encoding TTSS structural and secreted proteins. Pellicle formation was temperature dependent and pellicles did not form at 36degreesC, even though TTSS genes were expressed at this temperature. We found that cellulose is a component of the E. chrysanthemi pellicle but that pellicle formation still occurs in a strain with an insertion in a cellulose synthase subunit homolog. Since the TTSS, but not the cellulose synthase subunit, is required for E. chrysanthemi pellicle formation, this inexpensive assay can be used as a high throughput screen for TTSS mutants or inhibitors.

Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, peduncle and seed), and leaves, stems, and roots of seedlings. Some of the bacteria also occurred as epiphytes. The highest number of bacteria among the berry tissues sampled was isolated from the seed, and includes Bacillus, Burkholderia, Clavibacter, Curtobacterium, Escherichia, Micrococcus, Pantoea, Pseudomonas, Serratia, and Stenotrophomonas. This is the first survey of the endophytic bacteria diversity in various coffee tissues, and the first study reporting endophytic bacteria in coffee seeds. The possible role for these bacteria in the biology of the coffee plant remains unknown. C1 USDA, ARS, Insect Biocontrol Lab, Beltsville, MD 20705 USA.

We examined the association between this vitamin and BMD in 2576 adults. Men with plasma B-12 < 148 pM had significantly lower BMD at the hip, and women at the spine, relative to those with higher B-12, and trends were similar for both at all sites. Low vitamin B-12 may be a risk factor for low BMD. Introduction: Vitamin B-12 is important to DNA synthesis and may affect bone formation. It has been linked to osteoblastic activity in clinical studies and cell culture. Materials and Methods: We examined the relationship between plasma vitamin B-12 status and BMD in 2576 adult participants in the Framingham Offspring Osteoporosis Study (1996-2001). BMD was measured by DXA at the hip and spine. Plasma vitamin B-12 was measured by radioassay. Mean BMD measures were estimated for four categories of vitamin B-12 concentration, based on commonly used cut-offs, using analysis of covariance, adjusted for age, BMI, physical activity score for the elderly (PASE), alcohol use, smoking status, total calcium and vitamin D intake, season of bone measurement, and for women, menopause status and current estrogen use. Further adjustment for protein intake and total homocysteine concentration was also performed. Results: Both men and women with vitamin B-12 concentrations <148 pM had lower average BMD than those with vitamin B 12 above this cut-off. These differences were significant (p < 0.05) for men at most hip sites and for women at the spine. Significance remained after further adjustment for protein intake and plasma homocysteine.

A combined tracer dilution method with deuterium to measure TBW and bromide to measure ECW was used to assess changes in ICW (as a proxy for the BCM) and in the ECW/ICW ratio (an indicator of water distribution) over the course of recovery in nine severely burned children. During the acute phase of recovery, ICW losses averaged (mean +/- SD) 2.2 +/- 2.0 liters (P =.02) or 18.5 +/- 0.4%. During the rehabilitative phase, mean ICW increased by 3.4 +/- 3.7 liters or 31.9 +/- 14%. The ECW/ICW ratio varied widely both between patients and during the course of the study. During the acute phase of recovery, the mean ECW/ICW ratio increased from 1.06 +/- 0.15 liters to 1.20 +/- 0.14 liters because the ECW compartment had expanded relative to the ICW compartment. During rehabilitation, the ECW/ICW ratio decreased from 1.20 +/- 0.14 liters to 0.86 +/- 0.20 liters, with a recoup of 1CW and continued ECW losses. Tracking ICW and the ECW/ICW ratio using the combined tracer dilution method is practical for monitoring BCM and water distribution in severely burned children. Taken together, the indices provide useful information about hydration and nutritional status in individuals recovering from severe burn injury.

In barley, this process is commercially important because it forms the basis for the malting and brewing industries. In this study, barleys and malts were mashed in the presence of compounds that specifically inhibited the four common proteinase classes. The efficacies of the proteinases in solubilizing proteins were in the order cysteine approximate to metallo > aspartic > serine approximate to 0, which roughly reflected how the inhibitors affected the mash endoproteolytic activities. It was previously believed that only the cysteine enzymes were involved. All four enzyme classes affected the free amino nitrogen concentration but none altered any of the other measured wort characteristics. With either single inhibitors or inhibitor mixtures, the effect of pH was as expected, based on earlier studies that indicated that cysteine and aspartic proteinases were most active at low pH values and the metalloproteinases were only active at high pH. At the North American commercial mashing pH of 6.0, about one third of the soluble protein of a typical wort came from ungerminated barley, half was solubilized during malting and the remaining 22% was released during mashing.

Coupled gas chromatographic electroantennographic detection (GC-EAD) analyses of pheromone gland extracts of female L. dispar sensu lato ( including both AGM and NAGM) on four GC columns (DB-5, DB-23, DB-210, and SP-1000) revealed a new trace component that eluted just before (DB- 5; DB- 210) or after (DB- 23, SP-1000) disparlure, and elicited strong antennal responses. Isolation of this compound by high-performance liquid chromatography and hydrogenation produced disparlure, suggesting that the new component had the molecular skeleton of disparlure, with one or more double bonds. Of all possible monounsaturated cis-7,8-epoxy2-methyloctadecenes, only cis-7,8-epoxy-2-methyloctadec-17-ene co-chromatographed with the insect-produced compound on all GC columns and elicited comparable antennal responses. In field experiments in Honshu (Japan) with enantioselectively synthesized compounds, (7R, 8S)-cis-7,8-epoxy-2-methyloctadec-17-ene (7R8S-epo-2me-17-ene-18Hy) was weakly attractive to male L. dispar, but was less effective as a trap bait than (+)-disparlure, and failed to enhance attractiveness of (+)-disparlure when tested in blends. The antipode, (7S, 8R)-cis-7,8-epoxy-2-methyloctadec-17-ene, was not attractive, and when added to (+)-disparlure and/or 7R8S-epo-2me-17-ene-18Hy reduced attractiveness.

AB Many mammals and birds roll on or rub themselves with millipedes that discharge benzoquinones. Chemicals transferred from millipedes onto the integument of anointing animals are thought to deter ectoparasites. We tested the lone star tick, Amblyomma americanum (L.), for responses to three widespread components of millipede defensive secretions, 1,4-benzoquinone; 2-methyl-1,4-benzoquinone (toluquinone); and 2-methoxy-3-methyl-1,4-benzoquinone (MMB). In toxicity tests, ticks were confined for 1 hr in filter-paper packets treated with serial dilutions of each of the benzoquinones or the commercial acaricide permethrin. Ticks were least affected by toluquinone, and most affected by permethrin. Of the benzoquinones, only MMB showed repellent activity. Behavioral assays were more sensitive than mortality for measuring the effects of the benzoquinones. Latencies for ticks to right themselves and to climb were greater with all compounds, even at the lowest concentrations, than with controls. Ticks exposed to low concentrations of benzoquinones appeared to recover over time, whereas those exposed to high concentrations exhibited behavioral abnormalities 1-3 mo later. Our results indicate that benzoquinones appropriated via anointing may reduce the tick loads of free-ranging animals, although key questions remain on the amounts of these compounds available to and effectively appropriated by anointing animals.

Fractionation of a sunflower head extract, by normal-phase flash column chromatography, resulted in an early eluting fraction exhibiting significant activity in an egg-laying bioassay. Compounds 1 and 2, along with ent-trachyloban-19-oic acid (3) and ent-kaur-16-en-19-oic acid (4), were isolated as the major components of this fraction and identified by their NMR and mass spectra. The purified compounds were individually tested for ovipositional activity in dose-response bioassays. In these bioassays, compounds 1 and 2 gave linear dose responses, with increasing numbers of eggs laid as the dosage of either increased. Compounds 3 and 4 failed to stimulate significant egg-laying at any of the dosages tested. A factorial design bioassay, using compounds 1 and 2, showed that 1 was relatively more stimulatory than 2, and that there was no synergistic effect on oviposition when the two compounds were combined.

Cav. subsp. sativa (Mill.) Thell.] seeds at levels of 1.0% w/w or higher. Covering the pots with Petri dishes containing the soil-seedmeal mixture decreased germination of both species at the lowest application rate (0.5% w/w), suggesting that the some of the phytotoxins were volatile. CH2Cl2, MeOH, and water extracts of the wetted seedmeal were bioassayed against wheat and sicklepod (Senna obtusifolia (L.) H. S. Irwin & Barneby) radicle elongation. Only the CH2Cl2 extract was strongly inhibitory to both species. Fractionation of the CH2Cl2 extract yielded two major phytotoxins, identified by gas chromatography - mass spectrometry and NMR as 2-propen-1-yl (allyl) isothiocyanate (AITC) and allyl thiocyanate (ATC), which constituted 80.9 and 18.8%, respectively, of the active fraction. When seeds of wheat, arugula and sicklepod were exposed to volatilized AITC and ATC, germination of all three species was completely inhibited by both compounds at concentrations of 5 ppm or less. In field studies, where seedmeal was applied at 0.50, 1.25, and 2.50 kg/m(2) and tarped with black plastic mulch, all of the treatments significantly reduced dry weight of bioassay plants compared to the tarped control, with the highest seedmeal rate decreasing dry matter to less than 10% of the control 30 d after seedmeal application. Field pennycress seedmeal appears to offer excellent potential as a biofumigant for high-value horticultural crops for both conventional and organic growers.

Postmenopausal women ( n = 13) ate two diets that were similar, except that, in one diet, 25 g high-isoflavone soy protein ( SOY) was substituted for an equivalent amount of meat protein ( control diet), for 7 wk each in a randomized crossover design. After 3 wk of equilibration, calcium retention was measured by labeling the 2-d menu with (47)Ca, followed by whole-body counting for 28 d. Urinary calcium and renal acid excretion were measured at wk 3, 5, and 7. Biomarkers of bone and cardiovascular health were measured at the beginning and end of each diet. Calcium was similarly retained during the control and SOY diets (d 28, percent dose, mean +/- pooled SD: 14.1 and 14.0 +/- 1.6, respectively). Despite a 15 - 20% lower renal acid excretion during the SOY diet, urinary calcium loss was unaffected by diet. Diet also did not affect any of the indicators of bone or cardiovascular health. Substitution of 25 g high isoflavone soy protein for meat, in the presence of typical calcium intakes, did not improve or impair calcium retention or indicators of bone and cardiovascular health in postmenopausal women.

SO JOURNAL OF CLINICAL MICROBIOLOGY LA English DT Article ID YEASTS; SACCHAROMYCES AB A yeast causing widespread infection of laboratory mice was identified from 26S rRNA gene sequences as Candida pintolopesii. To determine the relationship of C. pintolopesii with other members of the Kazachstania (Arxiozyma) telluris species complex, nucleotide sequences from domains 1 and 2 of the 26S rRNA gene, the mitochondrial small-subunit rRNA gene, and the RNA polymerase II gene were phylogenetically analyzed. That analysis resolved the 48 strains examined into five closely related species: K. telluris, Candida bovina, C. pintolopesii, Candida slooffiae, and a previously unknown species. One or more strains of each of the last four species formed an ascosporic state much like that of K. telluris. To place these ascosporogenous strains taxonomically, it is proposed that they be assigned to the teleomorphic genus Kazachstania as K. bovina (type strain NRRL Y-7283, CBS 9732, from the nasal passage of a pigeon), K. heterogenica (type strain NRRL Y-27499, CBS 2675, from rodent feces), K. pintolopesii (type strain NRRL Y-27500, CBS 2985, from the peritoneal fluid of a dead guinea pig), and K. slooffiae (type strain NRRL YB-4349, CBS 9733, from the cecum of a horse). On the basis of multigene sequence analyses, K. heterogenica appears to be a hybrid of K. pintolopesii and a presently unknown species. With the exception of K bovina, the phylogenetically defined species show a moderate degree of host specificity.

The purpose of this study was to characterize the ontogeny of the adaptive immune response in calves sensitized to the attenuated strain of Mycobacterium bovis, bacillus Calmette-Guerin. Holstein bull calves were nonvaccinated (n = 6, vaccination controls) or vaccinated subcutaneously ( n = 6) with bacillus Calmette-Guerin at 1 and 7 wk of age. Composition and functional capacities of blood mononuclear cell populations from calves were evaluated at 1 (prevaccination), 3, 6, 7, 8, 9, and 12 wk of age. Young adults (nulliparous heifers, n = 4) vaccinated in an identical manner were sampled concurrently to evaluate effects of animal maturity on the development of the adaptive immune response. Responses of nonvaccinated calves to recall antigen (Mycobacterium bovis purified protein derivative) ex vivo and in vivo (i.e., cutaneous delayed-type hypersensitivity) were minimal or nonexistent. Responses of cells from vaccinated calves and young adults to recall antigen, however, were evident as early as wk 2 after primary vaccination. Antigen-induced T cell subset proliferation, and secretion of interferon-gamma, nitric oxide, and tumor necrosis factor-alpha by cells from vaccinated calves were comparable to or greater than responses of vaccinated adults during the 11-wk study. Eleven weeks after primary vaccination, cutaneous responses of vaccinated calves and young adults to intradermal administration of antigen were pronounced and comparable, demonstrating the capacity of the bovine neonate to develop a vigorous cell-mediated immune response in vivo. Antibody responses (i.e., antibody concentrations in sera and in supernatants from antigen-stimulated cultures of blood mononuclear cells) of vaccinated calves, in contrast, were markedly lower than parallel responses of vaccinated adults. In conclusion, these results suggest that the bovine neonate can mount a vigorous, adult-like cell-mediated immune response when vaccinated at an early age.

Temperature was held constant at 26.7 degrees C. Photoperiod played a major role in diapause induction. Most nymphs (77.6 to 100%) hatching between 15 September and 15 February, about half of nymphs hatching in early March or early September, and few nymphs hatching between 15 March and 15 August (1.8 to 10.3%) developed into diapausing adults. Thus, early March and early September are transitional periods during which about half of newly-hatched nymphs will develop into diapausing adults. Between those periods, almost all bugs were reproductive, and outside of them, almost all were in diapause. Hypertrophied fat body coupled with underdeveloped accessory glands were used to classify male diapause, and hypertrophied fat body coupled with lack of mature eggs were used to classify female diapause.

Knowledge of the spatial patterns of the rice borer and associated damage in sugarcane would be useful in designing studies to further investigate the economic importance of this pest. We examined the respective spatial patterns of larvae, pupae, tunnels and damaged internodes using Taylor's power law for population estimates based on plots or sites within fields and based on fields. Estimates based on plots or sites featured smaller sample sizes and greater variability than estimates based on fields. Analyses based on plots or sites also indicated between-field heterogeneity in estimates of Taylor's b for small, medium and large larvae, and for pupae. Such heterogeneity was not observed for total larvae, tunnels and bored internodes. In contrast, analyses based on fields indicated that common-slopes models were appropriate for each population category. The inconsistencies between results of analyses for plots or sites compared with those for fields probably resulted from the inadequacy of population estimates derived from the smaller-sized sample units. Based on samples from fields, counts exhibited mild clumping except for medium-sized larvae (random distribution) and pupae (regular distribution). Our results indicate that counts of most population categories of the rice borer are mildly clumped and that the observed distribution pattern is sensitive to sample size.

The mean (+/- SE) production of acorns among 43 selected trees was 5,930 586 acorns per tree with a maximum production level of 16,969 acorns for one tree. Trees were selected in the spring of 2000 based on abundance of acomets. The mean ( SE) damage level to acorns was 33 (+/- 2) percent (determined by dissection). The floating method for assessing sound acorns overestimated acorn damage by 36 percent overall. Weevils accounted for approximately 66 percent of all damage to acorns. We found that the percentage of weeviled acorns was negatively correlated to total acorn production per tree. The rate of acorn drop was higher in October and November than in September. However, the percentage of acorns damaged by weevils was higher for acorns falling in September than for acorns failing in October or November. C1 USDA, Forest Serv, So Res Stn, Athens, GA 30602 USA.

Reductions in egg hatch and egg-to-adult survival in both irradiated parents and their F-1 progeny tended to be inversely proportional to dosage received. Hatch of eggs from untreated parents averaged 58.9% and fell to 4.6% when males were treated with 40 krad. Egg-to-adult survival was more severely curtailed than egg hatch, averaging 36.0% for untreated groups and 0% for 40 krad groups. F-1 progeny exhibited greater reductions in egg hatch and egg-to-adult survival than their treated parents. Eggs from untreated females mated with F-1 male progeny averaged 58.9% hatch for the untreated control compared with 18.5% for the 10 krad group and 0.9% for the 20 krad group. Egg-to-adult survival in the untreated control averaged 38.4% compared with 5.4% for the 10 krad group and 0.1% for the 20 krad group. F-1 females were more susceptible to the effects of irradiation than F-1 males. Mortality in the 5 and 10 krad groups was similar to the untreated control, but fell abruptly at 15 krad and again at 40 krad.

A priori, the moral hazard effect on input use is indeterminate. This paper empirically assesses the input use impact of the increasingly popular, and federally subsidized, risk management instrument of revenue insurance and the extent to which its effects on input use may differ from those of the older yield based instruments. We conclude that among winter wheat farmers, those who purchase revenue insurance tend to spend less on fertilizers but do not appreciably alter pesticide expenditures. Thus, any improved environmental outcomes due to crop insurance are likely due to reduced fertilizer not pesticide use. When the environmental indicators included indicated a potential environmental fragility (i.e. high erosion, pesticide leaching or pesticide runoff potential), the input use equation suggested that fertilizer expenditures decreased. Revenue insurance undoubtedly further reduces fertilizer applications on these fields as well, but the marginal environmental benefit of revenue insurance is lessened because the reduction, where it matters most, accrues on land on which fertilizer use has already been curtailed to some degree.

Iron, aluminum, and manganese oxides; organic matter; and phosphates, carbonates, and sulfides are important sinks for trace elements in soil-residual systems. The pH of the soil-residual system is often the most important chemical property governing trace element sorption, precipitation, solubility, and availability. Trace element phytoavailability in residual-treated soils is often estimated using soil extraction methods. However, spectroscopic studies show that sequential extraction methods may not be accurate in perturbed soil-residual systems. Plant bioassay is the best method to measure the effect of residuals on phytoavailability. Key concepts used to describe phytoavailability are (i) the salt effect, (ii) the plateau effect, and (iii) the soil-plant barrier. Metal availability in soil from metal-salt addition is greater than availability in soil from addition of metal-containing residuals. Plant metal content displays plateaus at high residual loadings corresponding to the residual's metal concentration and sorption capacity. The soil-plant barrier limits transmission of many trace elements through the food chain, although Cd (an important human health concern) can bypass the soil-plant barrier. Results from many studies that support these key concepts provide a basis of our understanding of the relationship between trace element chemistry and phytoavailability in residual-treated soils. Research is needed to (i) determine mechanisms for trace element retention of soil-residual systems, (ii) determine the effect of residuals on ecological receptors and the ability of residuals to reduce ecotoxicity in metal-contaminated soil, and (iii) predict the long-term bioavailability of trace elements in soil-residual systems.

Here we review research on factors controlling net N mineralization as well as research on laboratory and field modeling efforts, with the objective of highlighting areas with opportunities for additional research. Among the factors controlling net N mineralization are organic composition of the residue, soil temperature and water content, drying and rewetting events, and soil characteristics. Because C to N ratio of the residue cannot explain all the variability observed in N mineralization among residues, considerable effort has been dedicated to the identification of specific compounds that play critical roles in N mineralization. Spectroscopic techniques are promising tools to further identify these compounds. Many studies have evaluated the effect of temperature and soil water content on N mineralization, but most have concentrated on mineralization from soil organic matter, not from organic residues. Additional work should be conducted with different organic residues, paying particular attention to the interaction between soil temperature and water content. One- and two-pool exponential models have been used to model N mineralization under laboratory conditions, but some drawbacks make it difficult to identify definite pools of mineralizable N. Fixing rate constants has been used as a way to eliminate some of these drawbacks when modeling N mineralization from soil organic matter, and may be useful for modeling N mineralization from organic residues. Additional work with more complex simulation models is needed to simulate both gross N mineralization and immobilization to better estimate net N mineralized from organic residues.

The extent of our knowledge about the chemicals and the impact on recycling programs varies from high to very low. Two significant challenges in regulating these materials are to accurately determine the concentrations of the organic compounds in residuals and to appropriately estimate the risk that the chemicals present from land application or public distribution. This paper examines both challenges and offers strategies for assessing the risks related to the occurrence of organic compounds in residuals used as soil amendments. Important attributes that must be understood to appropriately characterize and manage the potential risks for organic chemicals in biosolids include toxicity and dose response, transport potential, chemical structure and environmental stability, analytical capability in the matrix of interest, concentrations and persistence in waste streams, plant uptake, availability from surface application versus incorporation, solubility factors, and environmental fate. This information is complete for only a few chemicals. Questions persist about the far greater number of chemicals for which toxicity and environmental behavior are less well understood. This paper provides a synopsis of analytical issues, risk assessment methodologies, and risk management screening alternatives for organic constituents in biosolids. Examples from experience in Wisconsin are emphasized but can be extrapolated for broader application. C1 Wisconsin Dept Nat Resources, State Residuals Coordinator, Madison, WI 53703 USA.

Recently, a method was proposed using only ground-penetrating radar (GPR) and digital elevation maps (DEMs) to identify locations where subsurface water converged into discrete pathways. For this study, the GPR protocol for identifying horizontal subsurface flow pathways was extended to a 3.2-ha field, uncertainty is discussed, and soil moisture and yield patterns are presented as confirming evidence of the extent of the subsurface flow pathways. Observed soil water contents supported the existence of discrete preferential funnel flow processes occurring near the GPR-identified preferential flow pathways. Soil moisture also played a critical role in the formation of corn (Zea mays L.) grain yield patterns with yield spatial patterns being similar for mild and severe drought conditions. A buffer zone protocol was introduced that allowed the impact of subsurface flow pathways on corn grain yield to be quantified. Results indicate that when a GPR-identified subsurface clay layer was within 2 m of the soil surface, there was a beneficial impact on yield during a drought year. Furthermore, the buffer zone analysis demonstrated that corn grain yields decreased as the horizontal distance from the GPR-identified subsurface flow pathways increased during a drought year. Averaged real-time soil moisture contents at 0.1 m also decreased with increasing distance from the GPR-identified How pathways. This research suggests that subsurface flow pathways exist and influence soil moisture and corn grain yield patterns. C1 USDA ARS, Hydrol Lab, Inst Nat Resources, Beltsville, MD 20705 USA.

Biosolids were surface-applied to square 0.5-m(2) plots at four rates (0, 7, 34, and 90 dry Mg ha(-1)) on each of three soil-cover combinations in Chihuahuan Desert grassland and shrubland. Infiltration and erosion were measured during two seasons for three biosolids post-application ages. Infiltration was measured during eight periods of a 30-min simulated rain. Biosolids application affected infiltration rate, cumulative infiltration, and erosion. Infiltration increased with increasing biosolids application rate. Application of biosolids at 90 dry Mg ha(-1) increased steady-state infiltration rate by 1.9 to 7.9 cm h(-1). Most of the measured differences in runoff among biosolids application rates were too large to be the result of interception losses and/or increased hydraulic gradient due to increased roughness. Soil erosion was reduced by the application of biosolids; however, the extent of reduction in erosion depended on the initial erodibility of the site. Typically, the greatest marginal reductions in erosion were achieved at the lower biosolids application rates (7 and 34 dry Mg ha(-1)); the difference in erosion between 34 and 90 dry Mg ha(-1) biosolids application rates was not significant. Surface application of biosolids has important hydrological consequences on runoff and soil erosion in desert grasslands that depend on the rate of biosolids applied, and the site and biosolids characteristics.

Chemical additives to reduce or mask odors are one option for producers; however, many chemicals are too expensive or are too unstable to use safely. This project provides a preliminary evaluation of nitrate or nitrate + anthraquinone as additives in controlling odors from limed biosolids. Over a twenty-four day period, odors were measured in the headspace over several treatment levels using two different chemical analysis tools along with olfactometric evaluation-of odor intensity and hedonic tone. On six days during the sample period, hydrogen sulfide was measured using a Jerome 631X, a sensor that also responds to other reduce sulfur gases. Other specific sulfides, amines, and mercaptans were also determined using solid phase microextraction with gas chromatography-mass spectrometry. A simple sniff test approach was used with six panelists on five days during the project. The chemical analysis results revealed that the addition of nitrate and especially nitrate + anthraquinone was effective in reducing concentrations of hydrogen sulfide and methylmercaptan when compared to untreated limed biosolids. However, the olfactometric results did not reveal any significant differences between treatments. The panelists also found that all treatments exhibited a fishy or ammonical character, indicative of amines, or ammonia. More advance olfactometric analysis utilizing dilution techniques might have been able to distinguish between treatments, but it is likely that amines were the dominant odorant released from all treatments. This preliminary project suggests that chemical addition of nitrate or nitrate + anthraquinone would be most effective in controlling odors from unlimed biosolids such as anaerobically digested materials.

These resins are used in the metal casting industry as a "sand binder" for making cores (used to produce cavities in molds) and molds for nonferrous castings. During the casting process, the cores and molds are subjected to intense heat from the molten metal. As a result, the organic resins undergo thermal decomposition and produce a number of complex organic compounds. In this study, the organics were tentatively identified by MS after pyrolysis of the resins at 750 degrees C. The major thermal decomposition products from the Novolac, PU, and furan resins were derivatives of phenol, benzene, and furan, respectively. Compounds identified that are of potential environmental concern were benzene, toluene, phenol, o- and p-xylene, o- and m-cresol, and polycyclic aromatic hydrocarbons. Pyrolysis of the Novolac resin resulted in the generation of the most compounds of environmental concern. Because there is interest in beneficially using foundry molding sands in manufactured soils and other agricultural products, it is necessary that organic thermal decomposition products be identified to ensure environmental protection.

The plant concentrates sludge from primary sedimentation basins in gravity thickeners (GT) and sludge from secondary sedimentation basins in dissolved air flotation (DAF) thickeners. The thickened sludge is pumped into blending tanks and then fed into centrifuges for dewatering. The dewatered sludge is then conditioned with lime before trucking out from the plant. DMDS, along with other volatile sulfur and nitrogen-containing chemicals, is known to contribute to biosolids odors. These models identified oxidation/reduction potential (ORP) values of a GT and DAF, the amount of sludge dewatered by centrifuges, and the blend ratio between GT thickened sludge and DAF thickened sludge in blending tanks as control variables. The accuracy of the developed regression models was evaluated by checking the adjusted R-2 of the regression as well as the signs of coefficients associated with each variable. In general, both models explained observed DMDS levels in sludge headspace samples. The adjusted R-2 value of the regression models 1 and 2 were 0.79 and 0.77, respectively. Coefficients for each regression model also had the correct sign. Using the developed models, plant operators can adjust the controllable variables to proactively decrease this odorant. Therefore, these models are a useful tool in biosolids management at WWTPs. C1 Univ Maryland, Dept Civil & Environm Engn, College Pk, MD 20742 USA. Univ Seoul, Dept Environm Engn, Seoul, South Korea.

To minimize the environmental impacts of 1,3-D, feasible and cost-effective control strategies are in need of investigation. One approach to reduce emissions is to enhance the surface layer of a soil to degrade 1,3-D. A field study was conducted to determine the effectiveness of composted steer manure (SM) and composted chicken manure (CKM) to reduce 1,3-D emissions. SM or CKM were applied to the top 5-cm soil layer at a rate of 3.3 or 6.5 kg m(-2). An emulsified formulation of 1,3-D was applied through drip tape at 130.6 kg ha(-1) into raised beds. The drip tape was placed in the center of each bed (102 cm wide) and 15 cm below the surface. Passive flux chambers were used to measure the loss of 1,3-D for 170 h after fumigant application. Results indicated that the cumulative loss of 1,3-D was about 48% and 28% lower in SM- and CKM-amended beds, respectively, than in the unamended beds. Overall, both isomers of 1,3-D behaved similarly in all treatments. The cumulative loss of 1,3-D, however, was not significantly different between the two manure application rates for either SM or CKM. The results of this study demonstrate the feasibility of using composted animal manures to control 1,3-D emissions. C1 USDA ARS, Anim Manure & Byprod Lab, Beltsville, MD USA.

The vapor of propylene glycol (PG), which was used as coolant in growth chambers, has been found to be toxic to corn (Zea mays L.) and soybean (Glycine max L.) plants. PG solution leaked from a valve packing system and volatilized to vapor, which was trapped in a semi-closed growth chamber. Symptoms of leaf edge chlorosis, later developing into necrosis, were observed on the third day of emergence or on the third day after moving healthy plants into the chamber. For young soybean plants, symptoms were slightly different from those observed in corn plants; the chlorosis symptoms were not uniformly distributed on all leaves. Some soybean leaves curled up and others had white spots. This problem was identified by using a portable photoionization detector to obtain instantaneous readings of total volatile organic compound concentrations inside the chambers. The presence of PG in selected chambers was verified using sample collection with solid phase microextraction (SPME) followed by analysis with multi-dimensional gas chromatography mass spectrometry (MD-GC-MS). This information is pertinent to researchers who use controlled environment to grow plants. C1 USDA ARS, Alternate Crops & Syst Labs, Beltsville, MD USA.

The bacterium was grown in LB minimal medium (pH 6.25) containing no antibiotics. Upon achieving steady state, samples were plated to tryptic soy agar (TSA) alone or supplemented (per ml) with 2 and 16 μ g oxytetracycline, 4 and 16 μ g tetracycline, 2 and 64 μ g kanamycin, and 0.25 and 2 μ g enrofloxacin. Regardless of growth rate, CFU of resistant ST from the TSA containing antibiotics was less than 2 x 10(1) except for 2 μ g kanamycin and 0.25 μ g enrofloxacin treatments (higher than 1 x 10(9) and 4 x 10(7) CFU of resistant ST for trials 1 and 2, respectively). Frequency of recovering resistant ST from the TSA containing the higher antibiotic concentrations was less than 1 in 10(9) for all antibiotics, but was higher on the media containing 2 μ g kanamycin and 0.25 μ g enrofloxacin at both slow and fast growth rates. In general, minimal susceptibility differences were detected for isolates from slow and fast dilution rates. C1 Texas A&M Univ, Dept Poultry Sci, College Stn, TX 77843 USA.

Type IV and VI glandular trichomes on the leaves of five wild tomato accessions of Lycopersicum hirsutum f. glabratum (PI 126449, PI 134417, PI 134418, PI 251304, and LA 407) grown under greenhouse conditions were counted. Major chemical compounds from glandular leaf trichomes of the accessions tested were extracted, purified, and quantified at different periods during the growing seasons by gas chromatography (GC) and mass spectrometry (GC/MS). The toxicity of two methylketones (2-undecanone and 2-tridecanone), the major constituents of the accessions tested, to adults of the sweetpotato whitefly, Bemisia tabaci (Gennadius) and fourth instar larvae of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), was determined using no-choice bioassays. 2-undecanone caused 80% mortality of the fourth instar larvae of the CPB at the highest concentration tested (100 mg 2-undecanone mL(-1) of acetone) while 2-tridecanone caused 72% mortality of whiteflies at 20 mg 2-tridecanone mL(-1) of 65% ethanol. The concentration of 2-undecanone and 2-tridecanone on the leaves of each of the five accessions of L. hirsutum f. glabratum and the mass spectra of 2-undecanone and 2-tridecanone are presented. Overall, the concentration of 2-undecanone on the leaves was significantly higher than 2-tridecanone. Concentration of the two methylketones varied among accessions and sampling season. Plants produced the highest concentration of 2-undecanone during the month of August. On average, each plant of accession PI 251304 provided 354 g fresh leaves (averaging about 52,353 cm 2 exposed leaf surface area) and produced 32.5 and 8.7 mg of 2-undecanone and 2-tridecanone, respectively. L. hirsutum f. glabratum accessions may become a valuable source of natural products, which could minimize reliance on synthetic pesticides.

The organic fractions in these soil amendments also influence metal reaction, particularly the adsorption and desorption of metals, which, in turn, determine the bioavailability of the metals and hence their phytotoxicities. In this study, a Quincy fine sandy (mixed, mesic, Xeric Torrip-samments) soil was treated with 0 to 160 g kg(-1) rates of either manure, sewage sludge (SS), or incinerated sewage sludge (ISS) and equilibrated in a greenhouse at near field capacity moisture content for 100 days. Following the incubation period, the soil was dried and adsorption of copper (Cu) was evaluated in a batch equilibration study at either 0, 100, 200, or 400 mg L-1 Cu concentrations in a 0.01M CaCl2 solution. The desorption of adsorbed Cu was evaluated by three successive elutions in 0.01M CaCl2 Copper adsorption increased with an increase in manure rates. At the highest rate of manure addition (160 g kg(-1) soil), Cu adsorption was two-fold greater than that by the unamended soil at all rates of Cu additions. With increasing rates of Cu additions, the adsorption of Cu decreased from 99.4 to 77.6% of Cu applied to the 160 g kg(-1) manure amended soil. The desorption of Cu decreased with an increase in rate of manure amendment. Effects of sewage sludge amendments on Cu adsorption were somewhat similar to those as described for manure additions. Likewise, the desorption of Cu was the least at the high rate of SS addition (160 g kg(-1)), although at the lower rates there was not a clear indication of the rate effects. In contrast to the above two amendments, the ISS amendment had the least effect on Cu adsorption. At the highest rate of ISS amendment, the Cu adsorption was roughly 50% of that at the similar rate of either manure or SS amendments, across all Cu rates.

These peptides were further purified using combinations of molecular 3 mass resolution and ion exchange chromatography. Molecular masses of the peptides were estimated at approximately 3,500 Da by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. lsoelectric focusing was used to determine the pI Values of the peptides. Amino acid sequences of the bacteriocins and more precise molecular masses were obtained by matrix-assisted laser desorption and ionization-time of flight (MALDI-TOF) analysis. The bacteriocin from P. polymyxa NRRL B-30507 had a pI of 4.8, that from P. polymyxa NRRL B-30509 had a pI of 7.2. that from P. polymyxa NRRL B-30508 had a pI of 4.8, and that from B. circulans NRRL B-30644 had a pI of 7.8.

We examined their ability to inhibit the growth of this foodborne pathogen and assess the relative effects of the inoculants on the alfalfa microbial community structure and function. Alfalfa seeds contaminated with a Salmonella cocktail were soaked for 2 It in bacterial suspensions from each inoculant tested. Inoculated alfalfa seeds were grown for 7 days and sampled during days 1, 3, and 7. At each sampling, alfalfa sprouts were sonicated for 7 min to recover microflora. from the surface, and the resulting suspensions were diluted and plated on selective and nonselective media. Total bacterial counts were obtained using acridine orange staining, and the percentage culturability was calculated. Phenotypic potential of sprout-associated microbial communities inoculated with biocontrol treatments was assessed using community-level physiological profiles based on patterns of use of 95 separate carbon sources in Biolog plates. Community-level physiological profiles were also determined using oxygen-sensitive fluorophore in BD microliter plates to examine functional patterns in these communities. No significant differences in total and mesophilic aerobe microbial cell density or microbial richness resulting from the introduction of inoculants on alfalfa seeds with and without Salmonella were observed. P. fluorescens 2-79 exhibited the greatest reduction in the growth of Salmonella early during alfalfa growth (4.22 log at day 1), while the market sprout inoculum had the reverse effect, resulting in a maximum log reduction (5.48) of Salmonella on day 7. Community-level physiological profiles analyses revealed that market sprout communities peaked higher and faster compared with the other inoculants tested. These results suggest that different modes of actions of single versus microbial consortia biocontrol treatments may be involved. C1 USDA ARS, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

Seeds were blanched and quartered, inoculated with conidia of A. flavus, placed on moistened filter paper in petri dishes, and incubated for 8 days at 28degreesC. Multiple regression analysis was used to account for the variation among lines with the use of fatty acid concentrations as independent variables. In test 1, linoleate accounted for 39 to 44% of the variation among lines for aflatoxin B I and 132 and total aflatoxin (26 to 27% after log transformation). Oleate accounted for substantial additional variation (27 to 29%) among lines (20 to 23% after log transformation). Other fatty acids accounted for small fractions of among-line variation. In test 2, linoleate accounted for about 35 to 44% of the variation among entries across traits (29 to 37% for log-transformed data); arachidate accounted for 19 to 29% (27 to 33% after log transformation). Eicosenoate accounted for a small part of the total entry variation. In both experiments, residual variation among entries was significant. Low-linoleate lines consistently contained more aflatoxin, whereas normal- to high-linoleate lines contained variable amounts. Although fatty acid concentrations accounted for significant portions of genetic variation, it is not practical to use them as predictors for susceptibility to aflatoxin contamination, especially for lines in the normal range for oleate and linoleate.

The ELIME technique entails sandwiching bacterial analyte between antibody-coated magnetic beads and an alkaline phosphatase-conjugated antibody. The beads (with or without bound bacteria) were localized onto the surface of magnetized graphite ink electrodes in a multiwell plate format. The enzyme substrate, I-naphthyl phosphate, was added, and conversion of substrate to an electroactive product was measured using electrochemical detection. With this technique, detection of whole, live E. coli O157:1-17 bacterial cells was achieved with a minimum detectable level of ca. 5 X 10(3) cells per ml in Tris-buffered saline or buffered apple juice in an assay time of ca. 80 min. With adjustment of pH, the ELIME response for the bacteria in either sampling medium was similar, indicating that apple juice components did not contribute to any discernible sample matrix effects.

One popular type of sandwich product is the tortilla wrap, which contains sliced luncheon meats and cheeses rolled within a flour tortilla. This study determined the radiation resistance of L. monocytogenes surface inoculated onto two types of commercially available wheat flour tortillas, processed cheese slices, and deli turkey meat. The D-10-values for L. monocytogenes (the radiation dose required to inactivate I log of the pathogen) were 0.27 kGy when inoculated onto two flour tortilla types, 0.28 and 0.30 kGy when inoculated onto two types of sliced processed cheeses, and 0.58 and 0.65 kGy when inoculated onto two types of sliced deli turkey meat. When two types of tortilla wraps were assembled from the individual components and L. monocytogenes was inoculated into the interfaces between the individual components, the D10-values were 0.27 to 0.37 kGy in the tortilla and cheese interfaces, 0.33 to 0.41 kGy in the cheese and turkey interfaces, and 0.25 to 0.33 kGy in the turkey and tortilla interfaces. The ability of ionizing radiation to reduce pathogen levels on the complex tortilla, cheese, and luncheon meat product was limited by the higher radiation resistance of L. monocytogenes when inoculated onto the ready-to-eat turkey-meat component.

Heat treatment reduced the rate of respiration and moisture loss during storage of the cut fruit. The treatment also reduced total microbial count during the 1st storage d and prevented growth of lactic acid bacteria that occurred in untreated fruit after 8 d in storage. Sensory evaluations indicate that heat treatment increased intensities of desirable attributes such as fruity melon and sweet aromatic flavors, and reduced undesirable flavors such as musty, sour, bitter, chemical and fermented. The study suggests that heat treatment would be useful in improving shelf life of fresh-cut fruit. C1 USDA ARS, So Reg Res Ctr, New Orleans, LA 70124 USA.

Fresh pickling cucumbers were blanched and brined with sterile spices and garlic oil. The product was stored at 5degreesC for 3 wk and then transferred to various abuse temperatures (16degreesC, 25degreesC, 30degreesC). Lactic acid bacteria (LAB) were isolated and characterized as potential biocontrol agents, and the isolates were tested for bacteriocin-like activity. A total of 118 LAB isolates were obtained. Among the LAB identified were species of Lactococcus, Leuconostoc, Lactobacillus, Weissella, and Enterococcus. Three isolates showed transient bacteriocin activity against-Listeria monocytogenes, and 7 isolates (Lactococcus) had bacteriocin-like activity against other LAB. Although it did not produce a bacteriocin, a Lactobacillus curvatus isolate (LR55) was found to have desirable characteristics for use as a biocontrol (competitive exclusion) culture to enhance the safety of nonacidified deli-type pickles.

The effect of Nutrim on the dough characteristics and noodles quality was tackled. The presence of Nutrim increased the final water absorption and dough tolerance as measured by Farinograph whereas the dough stability was decreased. The DSC (Deferential scanning Calorimetry) data showed that Nutrim, increased the onset or peak temperatures while the DeltaH was reduced by 25%. The resilience of Nutrim-enriched noodles was not significantly affected. The chewiness and hardness were reduced by Nutrim added at 20% and 30%, while cohesiveness was significantly increased by all 3 Nutrim levels. RVA (Rapid Visco Amylograph) profile showed higher peak viscosity in the presence of Nutrim. The 20% and 30% Nutrim levels increased the soluble fiber of the final product from 1.13% to 1.67% and 2.47%. The yellow color of noodles became darker with higher Nutrim amounts added. The addition of Nutrim produced dough with a more compact image with less space between the starch granules as measured by scanning electron microscopy when compared with the control. The rheological testing showed that the presence of Nutrim decreased flour suspension elastic properties. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Cereal Prod & Food Sci Unit, Peoria, IL 61604 USA.

The Addition of PGRF, up to 8%, enhanced batter viscosity and the coating properties of the rice batter. Oil uptake of the fried batter decreased with the addition of up to 5% PGRF Rice flour fried batters, with and without PGRF, were found to absorb substantially lower off, by as much as 51%, compared with the wheat batter. The fried okra coated with the rice batter containing 5% PGRF, when evaluated for sensory properties on appearance and surface attributes, was found to be superior or equal to those with the wheat batter and rice batter without PGRF. Particularly, its golden brown color is considered more desirable than the fighter yellow color of the other 2 entities. Similarly, most of its 1st-bite and after-chew properties were slightly better and were in the normal range of commercially available products. Specifically, its distinctive crispiness is considered a positive attribute, whereas its slightly higher tooth packing properties, while remaining in the range of commercial products, may be noticeable to some consumers.

Even nonrespondents, when interviewed on the telephone, indicated attitudes sensitive to these issues. We believe future conservation of nonindustrial private forestland (NIPF) lands will be successful if professionals design management alternatives sensitive to these attitudes and policy makers craft appealing and effective programs that are perceived as relevant.

Although rooted in traditional forestry disciplines, Digital Forestry draws from a host of other fields that, in the past few decades, have become important for implementing the concept of forest ecosystem management and the principle of sustainable forestry. Digital Forestry is a framework that links all facets of forestry information at local, national, and global levels through an organized digital network. It is anticipated that a new set of principles will be established when practicing Digital Forestry concept for the evolution of forestry education, research, and practices as the 21st century unfolds.

'Sorrento' is the most important Italian walnut variety. It is cultivated for both nuts and timber in the Campania Region. 'Sorrento' is a mixture of genetic entities and is best characterized as a 'landrace', which affects the homogeneity of important commercial parameters such as fruit size and yield. To clarify the genetic variability in walnuts grown in Campania and labelled as 'Sorrento', we analyzed ten plants that originated from 'Sorrento' seeds and six grafted 'Sorrento' clones, and compared them with six other walnut cultivars using Simple Sequence Repeats (SSRs) DNA markers. Primers derived from J. nigra L. amplified alleles at six SSR loci in Persian walnut. A total of 33 putative alleles were detected, nine of which were unique to one genotype. Two loci, WGA5 and WGA27, were particularly useful for distinguishing walnut varieties. Cluster analysis clarified the relatively large genetic distance between most of the 'Sorrento' plants and some genotypes labelled as 'Sorrento'. Despite the genetic diversity found among seed and vegetatively propagated plants, 'Sorrento' landrace trees can be identified and distinguished from other walnut varieties. These data present a starting point for characterising the range of genetic variability among 'Sorrento' plants. C1 Univ Naples Federico II, Dipartimento Sci Suolo Pianta & Ambiente, Portici, Italy.

One-year-old potted Fuji/M.9 trees were supplied with 1% N-15-labelled urea either by foliar or soil applications in May, July and September. Trees receiving only water served as controls. The trees were harvested 10 d after N-15 application, separated into shoots (leaves and current-year stems), stem (previous-year wood) and roots. Biomass, total N and N-15 contents of all tissues were determined. New shoot biomass and total tree biomass increased as the season advanced, while root biomass peaked in July. Leaf N uptake was higher than root uptake in May and September, while root N uptake was higher than leaf uptake in July. Leaf N uptake increased as the season advanced, while root N uptake was highest in July. The lowest N-15 recovery (11%) was obtained in May with soil N application, and the highest N-15 recovery (48%) was obtained in September with foliar N application. Our results suggest that foliar application of N early in the season, followed by soil N application in mid-season, then foliar application again late in the season is an efficient N management strategy for young trees.

Toward this end, 11 profiles of suspended-sediment concentration and fluid velocity were collected in supercritical conditions over low-relief antidunes in a recirculating laboratory flume. It was found that velocity profiles agreed well with the law of the wall, and that turbulence intensities were similar to those in clear-water flows. The classic Rouse equation was found to under-predict concentration values in the upper 60-80% of the flow depth and a slightly modified version was proposed and successfully tested against experimental data from the present study and others.

Feeding and oviposition by L. hesperus induce emission of plant volatiles, but studies to date do not address the role of plant volatiles in the host-searching behavior of A. iole. In this study, a four-arm olfactometer was used to test the responses of female parasitoids to odors emanating from cotton (Gossypium hirsutum L., Malvaceae) plants damaged by L. hesperus females, L. hesperus males, larvae of the nonhost Spodoptera exigua Hubner, or mechanically, or to odors from L. hesperus females alone. In addition, various plants damaged by L. hesperus females were evaluated in the olfactometer: cotton, alfalfa (Medicago sativa L., Fabaceae), common groundsel (Senecio vulgaris L., Asteraceae), annual ragweed (Ambrosia artemisifolia L., Asteraceae), and redroot pigweed (Amaranthus retroflexus L., Amaranthaceae). In all olfactometry bioassays, treatment odors were compared against three controls (humidified air). Results showed that A. iole females were consistently attracted to odors derived from different plant-L. hesperus complexes, while odors from plants subjected to nonhost (S. exigua) or mechanical damage and L. hesperus females alone were not attractive or only variably attractive. These findings suggest that while searching for hosts A. iole females use specific volatiles induced by L. hesperus feeding and oviposition to locate hosts inhabiting a wide variety of plants, including annual and perennial species from four plant families. It was suggested that future research should seek to identify the chemical elicitors involved in the release of plant volatiles attractive to A. iole females.

Ecdysteroid content of fractions was determined by enzymeimmunoassay (EIA). The only delectable ecdysteroids that were present insignificant amounts in whitefly extracts were ecdysone and 20-hydroxyecdysone. The concentrations of 20-hydroxyecdysone in B. tabaci and T. vaporariorum extracts, respectively, were 40 and 15 times greater than the concentrations of ecdysone. The identity of the two ecdysteroids was confirmed by normal phase high performance liquid chromatography (NPHPLC). When ecdysteroid content of RPHPLC fractions was assayed by radioimmunoassay (RIA), small amounts of polar ecdysteroids were also detected indicating that these ecdysteroids have a very low affinity for the antiserum used in the EIA. Ecdysteroid at 10.4 mM administered by feeding stimulated 2nd instar whitefly nymphs to molt. Based on our results, it appears that 20-hydroxyecdysone is the whitefly molting hormone.

In a recently published article, the clarity and consistency of the terms pathogenicity and virulence as used in invertebrate pathology were called into question, and a revision of these terms was proposed. Our objective was to examine definitions of pathogenicity and virulence and their use in invertebrate pathology, and respond to this article. Although usage of the terms pathogenicity and virulence varies, we found considerable consistency in the published definitions of these terms in the invertebrate pathology literature throughout the history of the discipline, as well as among related disciplines such as medicine and microbiology. We did not find the established definitions to be lacking in clarity or utility. Therefore, we recommend that the definition and use of these terms adhere to precedence. Specifically, pathogenicity is the quality or state of being pathogenic, the potential ability to produce disease, whereas virulence is the disease producing power of an organism, the degree of pathogenicity within a group or species. Pathogenicity is a qualitative term, an "all-or-none" concept, whereas virulence is a term that quantifies pathogenicity. (C) 2004 Elsevier Inc. All rights reserved.

Traditionally, ET from agricultural fields has been estimated by multiplying the weather-based reference ET by crop coefficients (K-c) determined according to the crop type and the crop growth stage. Recent development of satellite remote sensing ET models has enabled us to estimate ET and K-c for large populations of fields. This study evaluated the distribution of K, over space and time for a large number of individual fields by crop type using ET maps created by a satellite based energy balance (EB) model. Variation of K-c curves was found to be substantially larger than that for the normalized difference vegetation index because of the impacts of random wetting events on K-c especially during initial and development growth stages. Two traditional K-c curves that are widely used in Idaho for crop management and water rights regulation were compared against the satellite-derived K, curves. Simple adjustment of the traditional K-c curves by shifting dates for emergence, effective full cover, and termination enabled the traditional curves to better fit K-c curves as determined by the EB model. Applicability of the presented techniques in humid regions having higher chances of cloudy dates was discussed. C1 Univ Idaho, Res & Extens Ctr, Kimberly, ID 83341 USA.

The dual crop coefficient (K,) method of the Food and Agricultural Organization of the United States (FAO) Irrigation and Drainage Paper No. 56 (FAO-56) is intended to improve daily simulation of crop ET by considering separately the contribution of evaporation from soil. The dual method utilizes "basal" crop coefficients representing ET from crops having a dry soil surface and separately predicts evaporation from bare soil based on a water balance of the soil surface layer. Three extensions to the evaporation calculation procedure are described here that are intended to improve accuracy when applications warrant the extra complexity. The first extension uses parallel water balances representing the portion of the soil surface wetted by irrigation and precipitation together and the portion wetted by precipitation alone. The second extension uses three "stages" for surface drying and provides for application to deep cracking soils. The third extension predicts the extraction of the transpiration component from the soil surface layer. Sensitivity and analyses and illustrations indicate moderate sensitivity of daily calculated ET to application of the extensions. The dual K, procedure, although relatively simple computationally and structurally, estimates daily ET as measured by lysimeter relatively well for periods of bare soil and partial and full vegetation cover.

Following digestion of polygalacturonic acid (PGA) with a monocomponent endo-polygalacturonase (EPG), more than 70 GA oligomer peaks could be resolved using a convex/linear ammonium formate gradient. Linear calibration curves were produced for 0.015-1.0% mono-, di-, and tri-GA. The mass response for mono-GA differed from those for di- and tri-GA, as evidenced from the slope of the calibration curve regression lines (1.611 +/- 0.0201 for-mono-GA vs. 1.3068 +/- 0.0291 and 1.3004 +/- 0.0262 for di-, and tri-GA, respectively). The degree of polymerization (DP) appeared to affect mass response as the trend line for log-transformed peak areas of DP 3, 4, 6, and 8 oligomers had a slope of -0.0304 +/- 0.0032 (r(2) = 0.98). Buffer concentration also affected mass response. ANOVA of peak areas from isocratic elution of trimer and hexamer with 50 mM to 0.8 M ammonium formate indicated mass response was dependent on buffer concentration for each oligomer (P<0.005), although Duncan's Multiple Range Test described concentration ranges within which mass response was not affected (P<0.05).

Bovine mammary development is driven by many of the same classic mammogenic hormones studied in murine models, yet histologic features of bovine mammary development differ from that of rodent models. Most notably, terminal end buds, as they have been described for murine models, do not exist in the bovine mammary gland. However, among the most important common features of mammary development in disparate species is the involvement of histologically distinct, lightly staining epithelial cells as putative stem and progenitor cells. Although stem cell research has often focused on mammary development, mammary stem cells seemingly provide the basis for mammary growth and cell turnover in the mature animal. These cells provide an obvious focus for research aimed at increasing the efficiency of milk production. This review addresses recent findings concerning the histology and molecular physiology of putative bovine mammary stem and progenitor cell populations, areas where more study is critically needed, and areas where studies of bovine mammary physiology may present a unique opportunity to better understand mammary physiology in many species.

Dielectric constant and loss-factor data are presented graphically for apple, avocado, banana, cantaloupe, carrot, cucumber, grape, orange, and potato, showing dielectric constants ranging from values of several hundred at 10 MHz to less than 100 at 1.8 GHz and loss factors on the order of one thousand at 10 MHz to less than 20 at 1.8 GHz. The dielectric loss factor increased consistently with increasing temperature at frequencies below 1 GHz. The dielectric constant increased with temperature at lower frequencies, but it decreased with temperature at the higher frequencies. This reversal of the sign of the temperature coefficient occurred at some point in the frequency range between 20 and 120 MHz where the temperature dependence of the dielectric constant was zero. At frequencies below this point, ionic conduction dominates the dielectric behavior, but above that point dipolar relaxation appears to control the behavior. Multiple linear regression provided equations for calculation of the loss factor in the frequency range from 10 to 300 MHz at temperatures from 5 to 65 degrees C. The data provide new information useful in understanding dielectric heating behavior and evaluating dielectric properties of such agricultural products for quality sensing applications.

Structure elucidation of two major components of the peptide mixture, cicadapeptins I and II (1 and 2), was accomplished by amino acid analysis and various MS, 1-D NMR, and 2-D NMR experiments. Both compounds are acylated at the N-terminus by n-decanoic acid and amidated at the C-terminus by 1,2-diamino-4-methylpentane. The amino acid sequence of cicadapeptin I is N-terminus-Hyp-Hyp-Val-Aib-Gln-Aib-Leu-C-terminus. Ile substitutes for Leu in cicadapeptin H. To our knowledge, this is the first report from fungi of consecutive Hyp or Pro residues in a nonribosomal linear peptide. ROESY data indicated that the cicadapeptins adopt a helical conformation.

A multispectral imaging system, which is capable of acquiring four spectral images simultaneously, was used to measure spectral scattering from "Red Haven" peaches, harvested at different ripening stages from two orchards, at wavelengths of 680, 880, 905 and 940nm. Soft peaches had broader scattering profiles than firmer ones, which was most pronounced at 680nm, the wavelength that is related to chlorophyll absorption. An empirical model, the Lorentzian distribution function with three parameters, was proposed to fit the restructured (shifted) scattering profiles for all four wavelengths, with the mean coefficient of determination (r(2)) equal to or greater than 0.998. Multi-linear regression models were developed on relating Lorentzian parameters to fruit firmness. The best firmness predictions (r(2)= 0.757 and the standard error for validation or SEV= 14.57N or Newtons) were obtained when separate models were developed for each orchard. When data from two orchards were pooled, the model was able to predict fruit firmness with r(2)= 0.672 and SEV= 18.55N. The multi-spectral scattering technique is non-destructive, fast and relatively easy to implement and it provides a non-destructive means for measuring peach fruit firmness.

Successful calibrations have been obtained with NIR spectra collected from 3 to 16 consecutive 10 rum sections of the same wood core. The success of these calibrations might be due to an autocorrelation that exists between the adjacent sections of a core. In this study, we compared calibrations with spectra collected from consecutive 10mm sections to calibrations obtained with spectra collected from unrelated 10mm sections. Very similar calibration statistics were obtained with both sets of spectra, demonstrating that existing calibration success is not due to an autocorrelation.

The results helped to determine the calibration transfer needed for this case. The dependent variables assessed from clear and stained wood were lignin, extractives, modulus of elasticity (MOE), modulus of rupture (MOR) and density When the master instrument was used for both calibration and prediction, it was found that stain-insensitive equations for the five traits could be built. However, when a slave near infrared instrument was introduced without calibration transfer, three out of five predicted traits were significantly biased by the presence of stain. Further analysis revealed an interaction between stain and instrument indicating that instrument bias was also introduced during scanning with a slave. For both multiple linear regression (MLR) and principal components regression (PCR), it was found that if a trait needed more wavelengths (or principal components) for prediction of the dependent variable, bias due to blue stain became increasingly prominent. PCR was found to perform better than MLR when stain was introduced with no calibration transfer. Such a finding alludes that PCR works better than MLR under extrapolation conditions but is not intended to support a lack of calibration transfer. Finally, the Mallows C P diagnostic proved valuable in model selection although the well-known requirement of (C-P-p <= 0) appeared conservative. For MLR and PCR, a C-P-p <= 5 often yielded applicable models while C-p-p > 7 was about the threshold where model performance dropped.

A 2 x 2 factorial experiment was designed to include Cu-deficient (CuD) and Cu-adequate (CuA) male and female rats. Weanling rats of both sexes were randomly divided into 2 groups each and fed an AIN-93G diet with low (<0.3 mg/kg; CuD) or adequate Cu (5.0 mg/kg; CuA). After 19 d, rats were fed 1.0 g each of their respective diets labeled with Fe-59. Retained Fe-59 was monitored by whole-body counting for 12 d. Then, rats were killed for 59Fe and Fe measurements in blood and various organs. Duodenal enterocytes were isolated for Western blot analysis of Hp. Signs of Cu and Fe deficiency were evident in both sexes. CuD male rats absorbed 60% as much Fe as CuA male rats (P < 0.001), whereas CuD female rats absorbed 70% (P < 0.001) as much as CuA females, with no difference between the sexes. Hp protein in enterocytes of CUD rats of both sexes was only 35% of that in CuA rats. The biological half-life of Fe-59 in CuD rats was only 50% (P < 0.001) of that in CuA rats, suggesting that Fe turnover was faster in CuD rats than CuA rats. Serum, spleen, and kidney Fe were lower (P < 0.001) in CuD rats than in CuA rats. Duodenal mucosa and liver Fe were higher (P < 0.01) in CuD male rats than CuA rats. Duodenal Fe but not liver Fe was higher in CuD female rats than CuA rats. Liver Fe was much higher (<0.001) overall in females than males. The data suggest that Cu deficiency reduces Fe absorption in rats through reduced expression of duodenal Hp protein. C1 USDA ARS, Grand Forks Human Nutr Res Ctr, Grand Forks, ND 58203 USA.

In the current study, 2 experiments were performed to determine the role of intestinal metallothionein (MT) in the accumulation of duodenal Cd, and to determine whether endogenous rice grain Cd is as available as Cd exogenously incorporated into the grain. In Expt. 1. wild-type and MT-null mice were fed 40% rice diets containing marginal or adequate amounts of Fe, Zn, and Ca, and 240 mug Cd/kg. Duodenal Cd was 10 times higher in both wild-type and MT-null mice regardless of their mineral status. In Expt. 2. one group of rats was fed 40% rice diets in which Cd was incorporated into the rice during growth and maturation, and another group was fed 40% rice diets in which Cd was incorporated into the rice during cooking. Each group also was fed either marginal or adequate amounts of Zn, Fe, and Ca. After 5 wk, rats were given a single meal labeled with Cd-109 and the amount of label retained after 7 d was determined by whole-body counting. Rats with marginal mineral status retained 10 times more Cd-109 than those with adequate status,, however, there was no difference between rats fed endogenous or exogenous Cd rice. Although duodenal Cd concentration was 8 times higher in the marginally fed rats, MT concentration was unchanged. These 2 experiments indicate that MT induction its not involved in duodenal Cd accumulation in animals with marginal dietary status of Fe. Zn. and Ca. In addition, they support the hypothesis that marginal deficiencies of Fe, Zn, and Ca, commonly found in certain human populations subsisting on rice-based diets, play an important role in increasing the risk of dietary Cd exposure.

The purpose of this review was to examine and characterize age-related changes in SM mass and composition and to link these changes to corresponding changes in metabolism and disease. It can be concluded from several studies that SM mass decreases with advancing age in both men and women. The age-related reduction in SM, also known as sarcopenia, is related to a corresponding reduction in SM strength, and if left untreated, sarcopenia may lead to functional impairment and physical disability. An emerging body of evidence also suggests that age-related changes in the composition of SM, particularly the accumulation of lipids within SM fibers, may lead to metabolic disorders such as insulin resistance.

Whether cysteine is an essential amino acid for premature neonates remains controversial. Using a [C-13(6)]glucose precursor in very-low-birth weight (VLBW) premature neonates, we measured the C-13 content of cysteine in hepatically derived apolipoprotein (apo) B-100 and in the plasma to determine whether cysteine synthesis occurs and to relate minimum synthetic capacity to neonatal maturity. Methods: Twelve VLBW premature neonates (birth weight, 907 +/- 274 [SD] g; gestational age, 26,8 +/- 2.4 weeks) were studied on day of life 7.8 +/- 4.2 while on total parenteral nutrition (TPN) for 5.6 +/- 4.5 days. A 4-hour intravenous infusion of [C-13(6)] glucose was administered. Blood samples were obtained immediately before and at the end of the infusion. Isotopic enrichment of cysteine was determined by gas chromatography/mass spectrometry. Analysis of variance, Student's t test, and linear regression were used for comparisons. Results: The C-13 isotope ratio of apo B-100-derived cysteine after the [C-13(6)] glucose infusion was significantly higher than baseline (18.57 +/- 0.38 [SEM] vs 17.54 +/- 0.25 mol%, P < .05). The C-13 isotope ratio of plasma cysteine was also significantly higher than baseline (17.36 +/- 0.25 vs 16.91 +/- 0.16 mol%, P < .05). When expressed as a product/precursor ratio, the mole percent above baseline of [C-13]apo B-100 cysteine/[C-13(6)]glucose correlated with birth weight (r = 0.74, P < .01). Conclusions: Very low birth weight neonates are capable of cysteine synthesis as evidenced by incorporation of C-13 label into hepatically derived apo B-100 cysteine and plasma cysteine from a glucose precursor. The minimum capacity for intrahepatic cysteine synthesis appears to be directly proportional to the maturity of the neonate and may impact the capabilities of VLBW neonates to counteract oxidative stresses such as bronchopulmonary dysplasia and necrotizing enterocolitis.

Five species viz., Sorghum arundinaceum, Sorghum halepense, Sorghum versicolor, Sorghum virgatum and Pennisetum glaucum were found to become infected by both pathogens via inoculation with 10(6) conidia/ml. Species which did not become infected under these conditions included Pennisetum pedicellatum, Zea mays, and species of Panicum, Brachiaria, Cenchrus, Andropogon, Dichanthium, Chrysopogon, Iseilema, Bothriochloa and Chloris. Honeydew secretions were observed from infected flowers of susceptible plant species. There was marked variation in size of macroconidia of both C. sorghi and C. africana on different hosts on which the pathogens were able to establish symptoms. Dimorphism was observed for macroconidia produced on P. glaucum, as elliptical and spindle shaped macroconidia were observed. Based on inoculation under greenhouse conditions, we conclude that C. sorghi and C. africana may have similar host ranges. C1 Int Crops Res Inst Semi Arid Trop, Hyderabad, Andhra Pradesh, India.

Quantitative real-time PCR revealed that while a lipoxygenase gene (WCI-2) was strongly up-regulated during the incompatible interactions, genes encoding beta-1,3 endoglucanase (GNS) and an integral membrane protein (WIR1) were moderately responsive. Genes for thionin-like protein (WCI-3), PR-17-like protein (WCI-5), MAP kinase (WCK-1), phenylalanine ammonia-lyase (PAL), pathogenesis-related protein-1 (PR-1), receptor-like kinase (LRK10) and heat shock protein 70 (HSP70) were minimally responsive. The application of signaling molecules, salicylic acid (SA), methyl jasmonate (MJ) and abscisic acid (ABA), to insect-free plants demonstrated association of these genes with specific defense-response pathways. SA-induced up-regulation of a gene related to lipoxygenases that are involved in jasmonic acid (JA)-biosynthesis is suggestive of positive cross-talk between SA- and JA-mediated signaling pathways. Data suggest that alternative mechanisms may be involved since few of these classical defense-response genes are significantly up-regulated during incompatible interactions between wheat and Hessian fly.

TI Challenges, achievements and opportunities in allelopathy research SO JOURNAL OF PLANT INTERACTIONS LA English DT Review DE Allelopathy; allelochemicals; competition; microorganisms; interference; natural products; soil AB Allelopathy is defined as the suppression of any aspect of growth and/or development of one plant by another through the release of chemical compounds. Although allelopathic interference has been demonstrated many times using in vitro experiments, few studies have clearly demonstrated allelopathy in natural settings. This difficulty reflects the complexity in examining and demonstrating allelopathic interactions under field conditions. In this paper we address a number of issues related to the complexity of allelopathic interference in higher plants: These are: (i) is a demonstrated pattern or zone of inhibition important in documenting allelopathy? (ii) is it ecologically relevant to explain the allelopathic potential of a species based on a single bioactive chemical? (iii) what is the significance of the various modes of allelochemical release from the plant into the environment? (iv) do soil characteristics clearly influence allelopathic activity? (v) is it necessary to exclude other plant interference mechanisms?, and (vi) how can new achievements in allelopathy research aid in solving problems related to relevant ecological issues encountered in research conducted upon natural systems and agroecosystems? A greater knowledge of plant interactions in ecologically relevant environments, as well as the study of biochemical pathways, will enhance our understanding of the role of allelopathy in agricultural and natural settings. In addition, novel findings related to the relevant enzymes and genes involved in production of putative allelochemicals, allelochemical persistence in the rhizosphere, the molecular target sites of allelochemicals in sensitive plant species and the influence of allelochemicals upon other organisms will likely lead to enhanced utilization of natural products for pest management or as pharmaceuticals and nutraceuticals. This review will address these recent findings, as well as the major challenges which continue to influence the outcomes of allelopathy research.

Seedling/vegetative assays have demonstrated genotypic differences among bean genotypes for tolerance to At toxicity, but insufficient information is available to determine whether results are indicative of tolerance measured in the field on mature plants. A two-year field study was conducted to determine if snap bean cultivars 'Dade' and 'Tendercrop,' previously shown to respond differently for At tolerance in early vegetative assays, also exhibit differential Al tolerance as mature plants in field assays. Exchangeable Al varied from 0 to 10.67 cmol(c) kg(-1). In 1999, grain weights of 'Dade' and 'Tendercrop' were negatively associated with exchangeable At, but did not differ from each other in their association with exchangeable Al. In 2000, the grain weight of 'Dade' was lower than in 1999, but still negatively associated with exchangeable At. For 'Tendercrop', 2000 year effects also reduced grain weight, but so much so that no association between grain weight and exchangeable At was evident. 'Dade' and 'Tendercrop' differed in grain weight in the absence of At in 2000. This study demonstrates the complexity of genotypic response to acid soils with At toxicity and does not support the assumption that early vegetative assays can identify At tolerance in mature snap bean plants.

Variations among genotypes were observed in the rate of ureide catabolism when plants were grown in nutrient solutions deficient in Mn. One possible explanation is that the differences in ureide catabolism among genotypes might be related to differences in Mn uptake from Mn-deficient nutrient solutions. Therefore, the objective of this study was to compare Mn uptake among six soybean genotypes grown in nutrient solutions with differing Mn and nitrate concentrations. Manganese concentration in various plant tissues was measured, as were concentrations of ureide, alpha-amino acid, nitrate, and iron (Fe). The genotypes segregated into two distinct groups under Mn-deficient conditions, with one group having higher leaf Mn concentrations and higher leaf Fe concentrations when nitrate was excluded from the nutrient solution. These results indicated that there exist major differences among soybean genotypes in the mechanism for root uptake of Mn and Fe. In addition to the benefit of sustaining ureide catabolism and nitrogen fixation, those genotypes that readily recovered Mn and Fe from the solution might be especially useful in developing cultivars for soils low in available Fe that might otherwise result in soybean Fe chlorosis.

The objectives of this research were to (1) determine the ability of poultry litter, as the sole nutrient source, to provide macronutrients and support growth of cotton (Gossypium hirsutum L.) (2) evaluate the distribution of these nutrients within the different plant parts, and (3) estimate the efficiency with which these nutrients are extracted by cotton. The research was conducted in plastic containers filled with a 2:1 (v/v) sand: vermiculite.,rowing mix under greenhouse conditions. The treatments included broiler litter rates of 0, 30, 60, 90, or 120 g pot(-1) with or without supplemental Hoagland's nutrient Solution. Broiler litter supplied adequate amounts of the macronutrients nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) and supported normal growth of cotton. Tissue nutrient analysis showed that the concentration of N, P, K, and Mg in the upper mainstem leaves was within published sufficiency ranges for cotton growth. Evaluation of the N distribution indicated that the cotton plant partitions N to reproductive parts when faced with deficiency of this nutrient and favors allocating N to new leaf growth once the requirement for reproductive growth is met. The partitioning of P was similar to that of N but less distinct. Cotton extracted Mg and K with greater efficiency (up to 58%) than the other nutrients and stored these nutrients in older leaves. The extraction efficiency of N ranged between 21% at 120 g pot(-1) litter and 27% at 30 g pot(-1) litter. Phosphorus was the most poorly extracted nutrient, with only 16% of the total applied P extracted when 30 g pot(-1) litter was applied and only 6% extracted at the higher litter rates. This suggests that the same problem of P buildup that has been reported in soils under pasture may also occur when poultry litter is repeatedly applied to the same soil planted to cotton. These results show that broiler litter not only supplied enough N but also supplied the four other macronutrients (P. K, Ca, and Mg) in amounts sufficient to support normal cotton growth. This research implies that poultry litter can effectively substitute for several fertilizers to meet crop macronutrient (N, P, K, Ca, and Mg) needs in soils deficient in any or all of these nutrients.

Merr.) cultivar "Manokin." Plants were grown in sand cultures and irrigated with isoosmotic solutions containing ( 1) Cl- as the dominant anion, or ( 2) a mixture of salts containing equal molar amounts of SO42- and Cl-. Six treatments of each salinity type were imposed. Electrical conductivities of the irrigation waters ranged from 2.1 to 13.0 dSm(-1). Selenium (1 mg center dot L-1, 12.7 mu M) was added to all irrigation waters as Na2SeO4. Regardless of salinity type, soybean plants were generally taller under the low-salinity treatments in early vegetative stages of growth. Towards the end of vegetative stages and until final harvest, higher values of plant height, leaf area, and shoot dry weight were found at the intermediate salinity levels (5.0 and 9.2 dS m(-1)), and higher salinity in general led to increased soybean leaf chlorophyll on a unit-area basis. Shoot-to-root ratios decreased with increasing chloride salinity, while the ratios remained nearly constant under the sulfate salinity treatment. Plant uptake and accumulation of salt ions (Ca2+, Mg2+, Na+, Cl-), K+, total phosphorus (p), and total sulfur (s) were generally not related to the type of salinity, except total S, where higher concentrations were found in leaves, stems, and roots in the sulfate than under the chloride salinity treatment. Selenium concentration in leaves and seeds was about 4 mg kg(-1) at final harvest when irrigated with the sulfate-based saline waters. Under the chloride salinity treatment, Se level was found to be about three times higher in leaves and five times higher in seeds. In conclusion, different solution concentrations of SO42- and Cl- had no significant effect on soybean biophysical growth parameters or ion distribution. Whereas shoot-to-root ratios decreased with increasing chloride salinity, high-sulfate salinity reduced Se uptake by "Manokin" soybean.

A 2 x 7 factorial design with three replications was used to test the effects of water ionic composition and salinity, respectively, on emergence, survival, and mineral accumulation of the salt-tolerant cut flower Limonium perezii (Stapf) F. T. Hubb cv. 'Blue Seas.' Seeds (n = 100) were sown in each of 42 presalinized greenhouse sand tanks. Irrigation water composition represented saline drainage waters typically present in either the San Joaquin Valley (SJV) or the Imperial/Coachella Valleys (ICV) of California. Electrical conductivity levels of the treatment waters were 2.5 (control), 6, 8, 10, 12, 16, and 20 dS m(-1), respectively. Seedling emergence was monitored daily and leaf mineral concentrations (total sulfur (S), total phosphorus (P), Ca2+, Mg2+, Na+, K+, and Cl-) were determined three months after planting. A two-way ANOVA revealed that salinity had a significant effect on seedling emergence (F = 27.56; P < 0.01). Cumulative emergence showed a marked decrease above 12 dS m(-1) for both water treatments and tended to be greater from 6-10 dS m(-1) than at 2.5 dS m(-1). A significant interaction of salinity and water composition was found for survival (F = 2.90; P < 0.05). Survival approximated 90% in ICV and SJV treatments up to 8 and 10 dS m(-1), respectively, yet continued to decrease below 70% in both water treatments at 12 dS m(-1) and higher. Differences in leaf-mineral concentrations between ICV and SJV water composition can be attributed to differences in composition of irrigation waters. As salinity increased, leaf Ca2+, K+, and total P decreased, whereas Mg2+, Na2+, Cl-, and total S increased. Stem length showed a marked decrease above 2.5 and 6 dS m(-1) under ICV and SJV treatments, respectively, with SJV waters producing similar to 30% more marketable flowers at salinities up to 6 dS m(-1). Thus, Limonium perezii maybe produced commercially with moderately saline wastewaters. C1 ARS, USDA, George E Brown Jr Salin Lab, Riverside, CA 92507 USA.

Pers.] hay to manage manure nutrients may differ from production of hay intended for livestock consumption. The objective of this study was to determine the relationships between maturity and yield, nutrient concentration, and nutrient uptake in bermudagrass fertilized with swine effluent. Primary spring and summer growth of 'Coastal' hybrid and common bermudagrass was harvested every 7 d to 63 d maturity. Effluent applied to Brooksville silty clay loam (fine, smectitic, thermic Aquic Hapludert) during each harvest period contained 140 kg nitrogen (N), 240 kg potassium (K), and 25 kg phosphorus (P) ha(-1) (mean of 2 years). Coastal and common bermudagrass had similar trends for yield, nutrient concentration, and nutrient uptake. Dry-matter production followed a linear trend in the spring (maximum of 1.11 kg m(-2) after 63 d) and a quadratic trend in the summer (maximum of 0.96 kg m(-2) after 56 d). Herbage N concentration declined from 33 to 17 g kg(-1) during the spring and summer harvest period, while P concentration declined from 3.8 to 2.4 g kg(-1). Maximum K concentration (26 g kg(-1)) occurred at 28 d of growth. Nitrogen, P, and K uptake exhibited a quadratic response to increasing maturity during the spring and summer harvest periods, but maximum uptake was greater in the spring than in the summer. These results suggest that the spring harvest period is the best time to maximize nutrient uptake by delaying bennudagrass harvest to more mature stages.

The older planting had a fescue (Festuca arundinaceae Schreb.) ground cover that is grazed by cattle. In the young plantation, weeds were mowed and sprayed with herbicides once annually in the spring. Litter was applied at rates of 6.72 Mg ha(-1) and 13.44 Mg ha(-1) for one year in the spring in the young plantation and at 8.96 Mg ha(-1) for two years in the spring and once in late summer in the older plantation. Height growth and leaf nitrogen (N) concentrations were improved during the summer following litter applications in the young plantation, but neither diameter growth nor nut production increased in the older plantation. Second-year height growth treatment differences for the young plantation were not significant. The number of nuts increased in the second year, but differences between treatments were not significant. C1 Lincoln Univ, USDA, Forest Serv, N Cent Res Stn, Jefferson City, MO 65102 USA.

Supplemental phosphorus (P) fertilizer is often applied for optimum yields, but producers are required to reduce P levels in farm drainage waters. The objectives of this study were to relate optimum leaf P tissue concentration with yield in organic soil, and to determine optimum leaf sampling dates during the summer. Eight genotypes were planted at two locations, eight additional genotypes were planted at a third location, and eight more genotypes were planted at a fourth location. Crops were grown for three years. Measurements of leaf P concentration were repeated during growth seasons and over crop years for a total of six sampling dates at each location. Three fertilizer P treatments (0, 24, and 48 kg ha(-1) yr(-1)) were applied to all genotypes at each location. Leaf samples were partitioned into early-, mid-, and late-summer dates. Early-leaf samples had the widest range in leaf P concentrations compared with mid- and late-season leaf samples. Correlation analyses of yield vs. leaf P concentration across all treatments in early- and mid-summer were statistically significant (P < 0.05), but coefficients were low (r = 0.14 and 0.26, respectively). No consistent relationship across locations described the effect of leaf P tissue concentration on yield. Leaf P concentrations could not provide accurate P fertilization rates that will give maximum sugarcane yields and prevent over-fertilization of P. The highest potential for relating leaf P concentrations with yield appears to be from early leaf samples. C1 ARS, USDA, Sugarcane Field Stn, Canal Point, FL 33438 USA.

Growth may be constrained by soil infertility and toxic concentrations of aluminum (Al) and manganese (Mn) in acidic Oxisols and Ultisols. The effects of phosphorus (P) fertilization at time of planting, soil type, and seed source on koa growth were studied for three years. Phosphorus, applied as triple superphosphate and at rates of at least 300 kg P ha(-1), significantly increased height, basal stem diameter, crown volume, and aboveground wood biomass of trees from the local (Oahu) seed source, but not those from off island (Hawaii). Manganese toxicity in the Oxisol probably slowed growth of the off-site trees. The local seed source grew similarly in both soil types, but the survival rate was lower in the Ultisol, possibly due to its lower water-holding capacity. Increased growth due to fertilization suggested improved P status, but such improvement was not detected by foliar analysis.

Cohesive and flexible cast films were obtained by blending lignocellulosic fibers derived from orange waste and PVA with or without cornstarch. Films were evaluated for their thermal stability, water permeability and biodegradation properties. Thermogravimetric analysis (TGA) indicated the suitability of formulations for melt processing, and for application as mulch films in fields at much higher temperatures. Composite films were permeable to water, but at the same time able to maintain consistency and composition upon drying. Chemical crosslinking of starch, fiber and PVA, all hydroxyl functionalized polymers, by hexamethoxymethylmelamine (HMMM) improved water resistance in films. Films generally biodegraded within 30 days in soil, achieving between 50-80% mineralization. Both starch and lignocellulosic fiber degraded much more rapidly than PVA. Interestingly, addition of fiber to formulations enhanced the PVA degradation. C1 USDA, ARS, Western Reg Res Ctr, Albany, CA 94710 USA. Univ Pisa, Dept Chem & Ind Chem, Pisa, Italy.

P reaching the reservoir is thought to emanate from runoff from the surrounding farms, mainly as a result of manure spread on these farms. Efforts to address the problem have involved implementation of BMPs on the watersheds; however, the effectiveness of these practices is not known. This, study establishes a means of estimating BMP effectiveness, based on data available in the literature, and develops a tool that allows users to obtain BMP effectiveness estimates for their respective site soil and slope conditions. The tool offers stand-alone capabilities and has the potential to be linked to a GIS. An example is presented to illustrate toot application for effectiveness-based BMP selection, with a focus on a farm within the New York City watersheds.

In recent years, phosphorus (P) indices have been developed to provide information regarding nutrient loss potentials from animal waste application methods and topography. However, in many cases, these P indices have not been fully tested, especially in cultivated agriculture. Three factors commonly utilized in soil P indices for manure management are manure rate, manure incorporation, and slope. Rainfall simulations were conducted to examine the impact of these three factors on runoff losses of P on heavy clay soils under cultivated agriculture. Four manure litter (turkey titter) application rates (0, 4.5, 9.0, and 13.5 Mg ha(-1) (0, 2, 4, and 6 tons ac(-1))) were applied on two different slopes (5 and 9 percent) on a Heiden clay (fine, smectitic, thermic Udic Haplusterts). The litter was surface applied to a corn (Zeo mays L.) production area, with or without incorporation. The four application rates were also applied to a permanent bermudagrass (Cynodon dactylon (L.) Pers.) pasture on a 5 percent slope. A rainfall simulator was used to generate water runoff for 30 minutes from 1.5 by 2.0 M (5 by 6.5 ft) plots. Runoff samples were analyzed for runoff volume, sediment, sediment nitrogen (N) and P, dissolved ammonia nitrogen (NH4-N), nitrate nitrogen (NO3-N), and PO4-P. The results were analyzed using regression analysis techniques based on application rates. The dissolved NO3-N concentration was not affected by either litter incorporation or slope in the cultivated sites, but was greatly increased with increasing litter application rate in the pasture sites. Increased losses of dissolved NH4-N and PO4-P were observed with increasing litter application rate, with a significant reduction in tosses observed when litter was incorporated. However, increased slope did not significantly impact the level of runoff losses of dissolved NH4-N and PO4-P. C1 USDA ARS, Natl Soil Dynam Lab, Auburn, AL USA.

Evaluation of P indices is necessary to provide the basis of modification and improvement of their usefulness as P management tools. In this study, the ability of the Texas P index to estimate P loss potential was evaluated by comparison with measured annual P loads over three years on four new pasture and six new cultivated litter application sites in the Texas Blackland Prairie. The Arkansas and Iowa P indices were also evaluated. The Texas and Iowa versions were able to provide reasonable estimates of P toss potential as illustrated with significant linear relationships (p < 0.01) between P index values and measured annual P loads. In general, the P index values, Mehlich 3 soil test P, and poultry litter application rate were better correlated with dissolved P concentrations and loads (r(2) ranged from 0.12 to 0.91) than with total P and particulate P loads (r(2) ranged from 0.00-0.31). A major source of error in P index toad estimations was their inability to capture variability in annual soil erosion. This source of error was dramatically reduced by using measured erosion instead of estimated annual average erosion (average r(2) values increased from 0.24 to 0.58). White these results illustrate a potential for the P indices to make relative P loss assessments, research on incentives to prevent buildup of soil P levels, linkages between P levels in soils and receiving waters, and other important issues related to the use of P indices is warranted.

Effectiveness of heat treatment in controlling insects is determined by attainment of uniform temperatures between 50degreesC and 60degreesC. A unique surface area method was proposed and developed to assess the effectiveness of heat distribution. The pilot flour mill at Kansas State University, Manhattan, KS, was heated with natural gas (positive press-Lire) and electric (neutral pressure) heaters in June and August 1999, respectively. The proposed surface area method compared the two different heating systems and successfully quantified the under- and over-heated sections of the treated rooms at any given time during the treatments. A two-parameter nonlinear log-logistic equation was used to describe and predict the general trend in the floor surface area that is under 50degreesC as a function of treatment time, and percentage of floor surface area as a function of maximum floor temperature. With electric heating, time delays for temperature increase were considerably shorter than with gas heating. However, electric heating resulted in substantial amounts of under-heated floor areas (T < 50degreesC) throughout the facility at the end of the heat treatment. The methods provided here, especially when coupled with the contour maps of temperature, can be used to design and evaluate heat treatment strategies in grain and food processing facilities.

The effects of heating rates (1, 10, and 15 degrees C min(-1)), pre-treatment conditioning (30 degrees C + 6 h), and the difference between long-term laboratory cultures and recently isolated cultures on thermal mortality of fifth-instar navel orangeworm, Amyelois transitella (Walker), were studied using a heating block system. There was no significant difference in insect mortality resulting from heating rates of 10 and 15 degrees C min(-1). Temperature control at 1 degrees C min(-1) was more uniform than for the other heating rates, resulting in reduced variability for insect mortality. The mean mortality at the heating rate of 1 degrees C min(-1) was significantly lower than for the two faster heating rates only at 48 degrees C + 30 min. The pre-treatment conditioning of fifth-instar Amyelois transitella enhanced their thermotolerance only at certain temperature-time combinations. Fifth-instars from long-term laboratory and recently isolated cultures were equally susceptible to elevated temperatures. Therefore, thermal death kinetic information obtained from the long-term laboratory cultures can be used to develop thermal protocols against field pests. (c) 2004 Elsevier Ltd. All rights reserved.

Coils of corrugated paper placed on the grain surface were used to trap mature larvae seeking pupation sites. Temperatures in the grain (18-cm-deep) and in the bin headspace were recorded hourly, and grain moisture content was measured weekly. Weekly mean numbers of moth larvae, and adults of two natural enemies, trapped in the coils were used for tracking changes in their abundance over time. The most significant findings were: (1) a seasonal pattern of abundance in both moth species that persisted from farm to farm and year to year, and (2) the coincidence of the highest population levels with the lowest temperatures. With few exceptions, the moth populations increased in the fall, reached their highest levels in winter, and then declined to low levels by early spring. The persistence of this pattern suggests a seasonal regulatory mechanism, with onset of low temperature as the primary initiator of population decline and adversely high temperature as a contributor to its protraction through spring into early summer. This view is supported by our observations of temperature and moth abundance, in conjunction with published information on the biological limitations of the two species. However, other factors, such as predators, parasitoids, and viral infection, may have contributed to the final population collapse. Superimposed upon the seasonal trends were short-term, non-seasonal cycles of abundance with variable periods. Population theory suggests that predation, parasitism, disease, and competition may have produced these cycles. Published by Elsevier Ltd.

Salt-affected soils are most common in aridic moisture regimes, and secondary salinization proper management of irrigation. Estimates of the area of salt-affected soils vary widely, ranging from 6% to 10% of earth's land area, and 77 million hectares (Mha) of irrigated lands. Crop yields are drastically affected due to lack of availability of water, nutrients., and oxygen in the root zone. The magnitude of yield reduction depends on the crop, soil type, and management. The reduction in yield normally ranges from 10% to 90% for wheat, 30% to 50% for rice, 50% to 75% for cotton, and 30% to 90% for sugarcane. Crop yield can be enhanced by nutrient management (especially N), water management (irrigation with good quality water and appropriate drainage), use of soil amendments (manures and gypsum, etc.), and use of salt-tolerant varieties.

The data were obtained from an experiment conducted at the site-specific center pivot irrigation facility at Florence, SC, USA, during the 1999-2001 seasons. The field was divided into 396 plots and a water production function was estimated for each plot to determine the optimal amount of irrigation water for each plot. Net returns from VRA applications were compared with uniform applications. The results indicate that the VRA applications yielded larger net returns than the uniform applications. However, the VRT applications require additional equipment and control. The benefits of reduced irrigation water costs plus the value of increased yields must be greater than the additional costs associated with the VRT application. Because the VRT system used in this experiment was built for experimental research purpose, the costs were much higher than those that would have been used for commercial growers. Even for the commercial system, the additional costs of VRT are more than the benefits of using VRT. Thus, at present, the VRT application of irrigation water is not profitable compared to uniform applications for South Carolina. However, the costs of these equipment and controls are declining over time. Furthermore, the costs would be much smaller when VRT is widely adopted by producers and these equipment and controls are mass-produced.

Plains because of no-till systems and crop residue management. With improved precipitation storage in soil, producers now grow corn (Zea mays L.), proso millet (Panicum miliaceum L.), or sunflower (Helianthus annuus L.) in sequence with winter wheat (Triticum aestivum L.) and fallow. A long-term cropping systems study was started at Akron, Colorado in 1990 to evaluate rotations comprised of a diversity of crops, with the goal of developing rotations that minimize frequency of fallow. After 10 years, we examined ecological trends associated with soil structure, nutrient cycling, and pest management as affected by rotations. Soil structure and nutrient cycling improved with continuous cropping, whereas, arranging winter and summer annual crops in a cycle-of-four improved pest management. Producers are seeking rotations that not only are economical, but also improve soil quality; they view fallow and tillage as detriments to long-term sustainability. Therefore, we also suggest options for developing rotations with continuous cropping, based on insight gained from the Akron study. Soils in the Central Great Plains were severely damaged during the Dust Bowl era; producers seek to repair this damage with continuous cropping and no-till. But, a concern with continuous cropping is yield variability and financial risk, which producers previously managed with fallow. Crop-diversity and sequencing in conjunction with residue management and no-till may provide advantages that minimize need for fallow in risk management. C1 ARS, NGIRL, USDA, Brookings, SD 57006 USA.

Atrazine plus metolachlor were applied PRE and POST. Bentazon in 2002 and carfentrazone in 2003 were applied in mixture with atrazine plus metolachlor POST. More hairy vetch dry biomass was present in the HV-B system (2,941 kg/ha) than in the HV-D (1,397 kg/ha) and no hairy vetch (0 kg/ha) systems at 7 wk after planting corn (WAP). Live and desiccated hairy vetch in HV-B and HV-D systems suppressed pitted morning glory compared with no hairy vetch at 7 WAR Densities of barnyardgrass, carpetweed, smooth pigweed, or yellow nutsedge were not reduced in HV-D and HV-B systems compared with no hairy vetch. Hairy vetch cover crop residue in HV-D and HV-B systems had no effect on total weed dry biomass at 7 WAP compared with no hairy vetch. Corn yields were higher in the HV-D system, regardless of herbicide treatment, and the HV-B with broadcast-applied PRE plus POST herbicide treatment cornpared with no hairy vetch treatments in 2003. Corn yields were similar with band- and broadcast-applied PRE plus POST herbicides when no hairy vetch or all hairy vetch was desiccated at planting (HV-D). Higher costs associated with hairy vetch were offset by higher corn yields in the HV-D system compared with no hairy vetch in 2003, as net returns were similar in both systems. Applying PRE plus POST herbicides in a band resulted in similar net returns as broadcast herbicide application in the no hairy vetch and HV-D systems. These findings indicate that hairy vetch cover crop had little effect on reducing densities of weed species studied, higher costs associated with cover crops can be negated with higher corn yields, and herbicide inputs can be reduced by applying herbicides in a band vs. broadcast without reducing corn yields or economic returns.

With an emphasis on human-induced nutrient depletion, this paper described the causality among soil nutrient depletion, soil quality, crop production, socio-economic variables, and environmental condition. Then, global soil nutrient budgets of nitrogen (N), phosphorus (P), and potassium (K) were estimated for wheat (Triticum aestivum L.), rice (Oryza sativa), maize (Zea mays L.), and barley (Hordeum vulgare) production for the year 2000. As a result, there were unbalanced fertilization with surplus N in some developing countries and insufficient inputs in many developing and all least developed countries. Globally, soil nutrient deficits were estimated at an average rate (kg ha(-1) yr(-1)) of 18.7 N, 5.1 P, and 38.8 K, covering 59%, 85%, and 90% of harvested area in the year 2000, respectively, and annual total nutrient deficit was 5.5 Tg (1 Tg=10(12) g) N, 2.3 Tg P, and 12.2 Tg K, coupled with a total potential global production loss of 1, 136 Tg yr(-1). Besides socio-economic factors, the soil nutrient depletion can be attributed to insufficient fertilizer use, unbalanced fertilization, and nutrient depletion-induced soil fertility problems. Soil fertility problems associated with human-induced nutrient depletion are widespread worldwide. C1 Ohio State Univ, Carbon Management & Sequestrat Ctr, Columbus, OH 43210 USA.

The initial depth of the midpoints of the strain transducers beneath the undisturbed soil surface was 220 mm. Strain was determined in the vertical, longitudinal, and lateral directions. Initial lengths of strain transducers were approximately 118 mm for the longitudinal and lateral transducers and 136 mm for the vertical transducer. The tire dynamic load was 25 kN and the inflation pressure was 110 kPa, which was a recommended pressure corresponding to the load. In each of four replications, as the tire approached and passed over the strain transducers, the soil first compressed in the longitudinal direction, then elongated, and then compressed again. The soil was compressed in the vertical direction and elongated in the lateral direction. Mean natural strains of the soil following the tire pass were -0.200 in the vertical direction, +0.127 in the lateral direction, and -0.027 in the longitudinal direction. The mean final volumetric natural strain from the strain transducer data was -0.099, which was only 35% of the mean change in natural volumetric strain calculated from soil core samples, -0.286. This difference likely resulted from the greater length of the lateral strain transducer relative to the 69 mm lateral dimension of the soil cores. The strain transducer data indicated the occurrence of plastic flow in the soil during one of the four replications. These results indicate the complex nature of soil movement beneath a tire during traffic and emphasize a shortcoming of soil bulk density data because soil deformation can occur during plastic flow while soil bulk density remains constant.

We recently conducted a drying study on non-chrome-tanned leather made with a glutaraldehyde-tanning process. Results showed that the physical properties of leather, such as area retention and softness,, were affected significantly by the drying method. Data revealed that leather with inferior fracture energy often resulted in poor grainbreak. In addition, observations showed that drying methods using toggling produced higher areayield; however, it resulted in stiffer leather. Our research showed that residual water content plays an important role in controlling the softness of leather. Vacuum drying without toggling yields better toughness and softness. A dimensionless quantity "toughness index" showed a strong correlation with the resultant area retention, which agrees with our previous findings for chrome-tanned leather.

The defatted L. fendleri seeds also contain more than 30% protein. The objective of this study is to process and characterize this protein component for possible future uses in food. Hexane-defatted seed has more than 30% protein content. Defatted lesquerella meal was extracted sequentially with 0.5 M sodium chloride (2x), water, 70% ethanol, and 0.1 N sodium hydroxide (2x). Each sodium chloride extract was dialyzed against deionized water and centrifuged to separate the water-soluble fraction (albumin) from the salt-soluble fraction (globulin) before freeze-drying. The ethanol extract and the neutralized sodium hydroxide extracts (glutelin) were dialyzed against water and freeze-dried. Albumin had the highest proportion of lysine and sulfur amino acids per 16 g nitrogen among all the fractions analyzed. Glutelin and globulin accounted for the highest amount of protein nitrogen. SDS-PAGE of the reduced albumin, globulin, and glutelin showed the presence of several protein bands with M.W. ranging from 7 to 98 kDa. Nitrogen solubility of defatted lesquerella meal from pH 2 to 12 indicated a solubility minimum of 15% around pH 4.2 and a solubility of 75% at pH 11.5. Nonprotein nitrogen of defatted meal was 12% of total nitrogen. Defatted lesquerella meal has the potential for food use based on good nitrogen solubility and good amino acid composition.

BATSCH; LINKAGE MAP; RAPD MARKERS; NUCLEOTIDE-BINDING; INTERSPECIFIC CROSS; MYROBALAN PLUM; PRUNUS; ALMOND; CONSTRUCTION AB An F-2 population from a single F-1 plant from the cross of peach [Prunus persica (L.) Batsch] rootstock cultivars Harrow Blood (HB) x Okinawa (Oki) was used to locate the Mi locus, which conditions resistance to Meloidogyne incognita (race 1) (Kofoid and White) Chitwood. These data and comparison of common markers among published genetic linkage maps placed the Milocus on Prunus L. linkage group 2. Two restriction fragment length polymorphisms (RFLPs) [linked at 4.8 and 6.8 centimorgan (cM), repulsion phase] and one random amplified polymorphic DNA (RAPD) marker (linked at 9.5 cM, coupling phase) were linked to Mi. The RAPD marker was cloned, sequenced, and converted to a polymerase chain reaction (PCR)-based cleaved amplified polymorphic sequence (CAPs) marker. Clones of resistance gene analogs (RGA) developed from Oki were highly polymorphic when used as RFLP probes. The RGA's mapped to four linkage groups but clustered on two of the four linkage groups, providing limited coverage of the genome. Even so, they may be useful as markers for disease resistance genes that occur in other populations. The linkage maps of the HB x Oki F-2 population and a peach x almond (Prunus amygdalus Batsch) F-2 population were colinear in certain regions, however, a significant number of markers mapped to different linkage groups among the two populations. The locus for the blood-flesh trait (red-violet mesocarp) mapped to the top of linkage group 4. C1 Univ Calif Davis, Dept Pomol, Davis, CA 95616 USA.

(strawberry) and Rubus L. (raspberry and blackberry), the number of SSRs available is insufficient for genetic mapping. Our objective was to use and compare multiple approaches for developing additional SSRs for Fragaria and Rubus. The approaches included: the development of SSRs from GenBank sequences from species of varied relatedness to Fragaria and Rubus and identified with two different data-mining methods (BLAST and SSRIT); the evaluation of some previously published SSRs designed from related species;, and the development of SSRs from a genomic library made from F. xananassa Duschene ex Rozier 'Earliglow'.. When an SSR was developed from a known gene sequence, the location of the repeat in the gene was determined to evaluate the effect on amplification and polymorphism detection. Cross-generic amplification between closely related Fragaria and Rubus as well as transference from species of varied relatedness to Fragaria and Rubus also was evaluated and indicated limited transference within the subfamily Rosoideae. However, development of SSRs for Fragaria and Rubus from Rosa L. (rose) and Rosaceae genera outside Rosoideae was not efficient enough to be practical for new map development. SSRIT was superior to BLAST for identifying GenBank sequences containing repeats. SSRs developed from repeats found in either the 5'UTR (80% polymorphic) or 3'UTR (85% polymorphic) were most likely: to detect polymorphisms, compared with those developed from coding regions (30%). SSRs developed from the genomic library Were only slightly superior to GenBank-derived SSRs in their ability to detect polymorphisms.

Modified atmosphere packaging (MAP) has been used to maintain quality of fresh-cut produce, but O-2 depletion and excessive CO2 accumulation can be injurious. This study was conducted to evaluate the effect of delayed packaging and MAP using two different oxygen transmission rate (OTR) films on quality maintenance and shelf stability of fresh-cut romaine lettuce (Lactuca sativa L.). Romaine lettuce leaves were cut, washed, dried, and placed for 0, 4, 8, and 12 hours at 5 degreesC in ambient air before packaging. Fresh-cut samples were placed into packages prepared from films having OTRs of 8.0 and 16.6 pmol(.)s(-1.)m(-2.)Pa(-1), flushed with N-2 to reach an initial headspace O-2 level of 1.5 kPa O-2, and stored at 5 degreesC for up to 14 days. Delayed packaging affected gas composition, fermentative volatile production, off-odor development, color, CO2 injury, and tissue electrolyte leakage. With increasing delay before packaging, fermentative volatile production, off-odor development, and CO2 injury progressively decreased and discoloration increased. The modified atmospheres obtained with 16.6 OTR film increased discoloration when present, and generally had less off-odor development and CO2 injury compared to MAP with 8.0 OTR film. Delayed packaging affected overall quality of fresh-cut romaine lettuce packaged with both films. A12-hour delayed packaging into packages prepared from 8.0 OTR film maintained quality by inhibiting CO2 injury, off-odor development, and tissue electrolyte leakage. However, an 8-hour delayed packaging into packages prepared from 16.6 OTR film was better at maintaining the quality of fresh-cut romaine lettuce at 5 degreesC for 14 days. The results indicated that delayed packaging could be an alternative method to optimize or balance package O-2 during suboptimal OTR film packaging conditions.

To investigate these relationships, a digital elevation model was developed for a 16.2 ha old-growth bottomland hardwood-Pinus taeda forest in southern Arkansas. Overstory trees, saplings, seedlings, and herbaceous plants were analyzed in three 0.5 m elevation classes and by using indirect gradient analysis. Information was also collected on site factors (canopy cover, forest floor litter cover, and elevation), soil physical factors (bulk density and soil texture), soil moisture, and soil chemical factors (pH, electrical conductivity, organic matter, N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, and Na). Importance values for 35% of seedling species, 30% of overstory species, 22% of herbaceous species, and 8% of sapling species differed significantly by elevation class. Significant differences by elevation in species diversity, richness, and evenness were identified in the seedling stratum, while only sapling evenness differed by elevation. Seventy-four percent of the environmental characteristics produced significant differences by elevation except for soil texture (sand, silt, and clay), September soil moisture content, Mn, and Cu. Seventy percent of environmental variables were significantly correlated with elevation. Dominant environmental influences on species composition in all strata included elevation as well as many other correlated variables such as Fe, forest floor litter cover, bulk density, and Na. Results from this study suggest that differences in vegetation were primarily the result of subtle elevational variations. Restoration or management of these forests should carefully consider microtopographical influences.

If national food systems do not meet these demands, mortality and morbidity rates increase, worker productivity declines, livelihoods are diminished and societies suffer. Today, many food systems within the developing world cannot meet the nutritional needs of the societies they support mostly due to farming systems that cannot produce enough micronutrients to meet human needs throughout the year. Nutrition transitions are also occurring in many rapidly developing countries that are causing chronic disease (e.g., cancer, heart disease, stroke, diabetes, and osteoporosis) rates to increase substantially. These global developments point to the need to explicitly link agricultural technologies to human health. This paper reviews some ways in which agriculture can contribute significantly to reducing micronutrient malnutrition globally. It concludes that it is imperative that close linkages be forged between the agriculture, nutrition and health arenas in order to find sustainable solutions to micronutrient malnutrition with agriculture becoming the primary intervention toot to use in this fight.

Susceptibility to the disease is partly dependent on the genetic makeup of the host. This study documents clinicopathological findings and the distribution of abnormal prion proteins (PrPres) by immunohistochemical and Western blot techniques, in tissues of genetically susceptible sheep inoculated with US sheep scrapie agents. Four-month-old Suffolk lambs (QQ or HQ at codon 171) were inoculated (5 intracerebrally and 19 orally) with an inoculum (#13-7) consisting of a pool of scrapie-affected sheep brains. Intracerebrally inoculated animals were euthanized when advanced clinical signs of scrapie were observed. Orally inoculated animals were euthanized at predetermined time points (4, 9, 12, 15, and 21 months postinoculation [PI]) and thereafter when the animals had terminal signs of disease. All intracerebrally inoculated animals exhibited clinical signs of scrapie and were euthanized between 13 and 24 months PI. Spongiform lesions in the brains and PrPres deposits in central nervous system and lymphoid tissues were present in these sheep. In orally inoculated sheep, clinical signs of scrapie were seen between 27 and 43 months PI in 5/9 animals. The earliest detectable Prp(res) was observed in brainstem and lymphoid tissues of a clinically normal, orally inoculated sheep at 15 months PI. Three of the 4 clinically normal sheep were positive at 15, 20, and 49 months PI by PrPres immunohistochemistry. C1 USDA, Natl Anim Dis Ctr, ARS, Ames, IA 50010 USA.

Forty-five of 163 bison submitted for sale from 8 different bison farms died on 7 other destination farms. The outbreak began on day 50 after the sale, peaked between days 60 and 70, and ended on day 220. Twenty-one dead bison were confirmed to be MCF cases by clinical histories, pathology, and detection of ovine herpesvirus-2 DNA in their tissues with polymerase chain reaction assays. Twenty-four dead bison were classified as suspect MCF cases from clinical histories. No cases of MCF were observed among bison remaining on originating farms or resident bison mixed with sale bison on destination farms. There were no sheep reported within 3 km of originating or destination farms, limiting bison exposure to sheep to the auction facility, where sheep were present for less than 1 day. The outbreak provides an illustration of the temporal distribution of MCF mortality expected in bison and an estimate of the time from exposure until death from MCF after a single short exposure to sheep. The study provides evidence that bison with MCF do not transmit MCF to other bison. C1 Univ Saskatchewan, Western Coll Vet Med, Dept Large Anim Clin Sci, Saskatoon, SK S7N 5B4, Canada.

Excessive acetylcholine levels cause excessive synaptic neurotransmitter activity. In most animal species, whole blood is the preferred sample for evaluation of cholinesterase activity. Previous reports of cholinesterase activity in carp have involved sampling of serum, plasma, brain, liver, muscle, and heart. Whole-blood samples were obtained from 12 healthy koi (Cyprinus carpio). Whole-blood cholinesterase activity was measured in all 12 samples. Plasma cholinesterase activity was also measured in 4 samples. The overall average of the whole-blood cholinesterases was 0.08 mumol/ml/minute (SD = 0.024). The results for the plasma cholinesterases were similar, with an average of 0.08 mumol/ml/minute (SD = 0.012). Because these reference values are below the minimum detection limit for the method of analysis used, results from blood samples from koi suspected to be suffering from anticholinesterase toxicosis may be uninterpretable.

Traditionally, proficiency testing for polymerase chain reaction (PCR)-based assays has involved the use of clinical samples, samples "spiked" with live agents or DNA plasmids. Because of government regulations and biosecurity concerns, distribution of live high-consequence pathogens of livestock and poultry, such as avian influenza, is not possible, and DNA plasmids are not technically suitable for evaluating RNA virus detection. Therefore, a proficiency testing panel using whole avian influenza in a diluent containing a phenolic disinfectant that inactivates the virus while preserving the RNA for at least 8 weeks at -70 C was developed and used in a multicenter proficiency assessment for a type A influenza real-time reverse transcriptase (RT)-PCR test. The test, which was highly standardized, except for variation in the real-time RT-PCR equipment used, was shown to be highly reproducible by proficiency testing in 12 laboratories in the United States, Canada, and Hong Kong. Variation in cycle threshold values among 35 data sets and 490 samples was minimal (CV = 5.19%), and sample identifications were highly accurate (96.7% correct identifications) regardless of real-time PCR instrumentation.

None of the methods was able to isolate Salmonella from all positive samples. The relative sensitivity of the culture methods evaluated was 82%, 94%, 95%, and 78% for methods A, B, C, and D, respectively. The comparison of sensitivities showed that methods B and C performed significantly better (P < 0.05) than methods A and D. Although relative sensitivities of methods B and C were equal, from the 89 positive samples concomitantly detected by both, 35 (39.3%) had different serotypes (no match) isolated by each method. On the basis of the results of this study, it was concluded that culture methods differ on the isolation of S. enterica serotypes from naturally contaminated swine fecal samples. Depending on the objective(s) of investigations on the ecology and epidemiology of S. enterica in swine populations, a method or a combination of methods should be considered for more reliable results.

This method circumvents the traditional use of aphids to transmit CMV, a virus that is mechanically transmissible to many plant species but only with difficulty to gladiolus. Cartridges containing virus-coated gold microcarriers were prepared and the virus shot into Nicotiana benthamiana leaves and gladiolus corms and cormels. The biolistic procedure successfully transmitted three CMV isolates, two from serogroup I and one from serogroup II. Survival rates of two cultivars of gladiolus cormels and corms in sterile and non-sterile environments were compared. Infection rates of 100% were obtained when as little as 2 mug of virus was used in cartridge preparation. CMV remained viable after the Cartridges were stored for many months at 4degreesC.

Here we report the genomic sequence and comparative analysis of two pathogenic DPV isolates, W-848-83 (W83) and W-1170-84 (W84). The W83 and W84 genomes are 166 and 170 kbp, containing 169 and 170 putative genes, respectively. Nucleotide identity between DPVs is 95% over the central 157 kbp. W83 and W84 share similar gene orders and code for similar replicative, structural, virulence, and host range functions. DPV open reading frames (ORFs) with putative virulence and host range functions include those similar to cytokine receptors (R), including gamma interferon receptor (IFN-gammaR), interleukin 1 receptor (IL-1R), and type 8 CC-chemokine receptors; cytokine binding proteins (BP), including IL-18BP, 1FN-alpha/PBP, and tumor necrosis factor binding protein (TNFBP); serpins; and homologues of vaccinia virus (VACV) E3L, K3L, and A52R proteins. DPVs also encode distinct forms of major histocompatibility complex class 1, C-type lectin-like protein, and transforming growth factor beta1 (TGF-beta1), a protein not previously described in a mammalian chordopoxvirus. Notably, DPV encodes homologues of cellular endothelin 2 and IL-1R antagonist, novel poxviral genes also likely involved in the manipulation of host responses. W83 and W84 differ from each other by the presence or absence of five ORFs. Specifically, homologues of a CD30 TNFR family protein, swinepox virus SPV019, and VACV E11L core protein are absent in W83, and homologues of TGF-beta1 and lumpy skin disease virus LSDV023 are absent in W84. Phylogenetic analysis indicates that DPVs are genetically distinct from viruses of other characterized poxviral genera and that they likely comprise a new genus within the subfamily Chordopoxvirinae.

Eleven site-directed mutants were generated from a cloned infectious cDNA of PLRV and delivered to plants by Agrobacterium-mediated mechanical inoculation. Alanine substitutions of any of the three amino acids of the sequence EWH (amino acids 170 to 172) or of D177 disrupted the ability of the coat protein to assemble stable particles and the ability of the viral RNA to move systemically in four host plant species. Alanine substitution of E109, D173, or E176 reduced the accumulation of virus in agrobacterium-infiltrated tissues, the efficiency of systemic infection, and the efficiency of aphid transmission relative to wild-type virus, but the mutations did not affect virion stability. A structural model of the PLRV capsid predicted that the amino acids critical for virion assembly were located within a depression at the center of a coat protein trimer. The other amino acids that affected plant infection and/or aphid transmission were predicted to be located around the perimeter of the depression. PLRV virions play key roles in phloem-limited virus movement in plant hosts as well as in transport and persistence in the aphid vectors. These results identified amino acid residues in a surface-oriented loop of the coat protein that are critical for virus assembly and stability, systemic infection of plants, and movement of virus through aphid vectors.

We used firue-expansion radio-microphones and integrated detectors to Simultaneously monitor bat activity at 3 heights (30, 10, 2 m) in each habitat type. Variation in vegetative clutter among sampling heights and among habitat types allowed LIS to examine the differential effect of forest vegetation on the spatial activity patterns of clutter adapted and open-adapted bat species. Moreover, monitoring activity at 30, 10, and 2 in permitted Its to also compare bat activity above and below the forest canopy. We detected calls of 5 species or species groups: eastern red/Seminole bats (Lasiurus borealis/L. seminolus), eastern pipistrelles (Pipistrellus subflavus), evening bats (Nychceius humeralis), big brown bats (Eptesicus fuscus), and hoary bats (Lasiuruscinerius). At 2 and 10 m, bat activity was concentrated in riparian areas, whereas we detected relatively low levels of bat activity ill upland habitats at those heights. Activity was more evenly distributed across the landscape at 30 in. Bat activity levels above the forest canopy were almost 3 times greater than within or below the canopy. We detected significantly greater activity levels of 2 open-adapted species (hoary and big brown bats) above rather than within or below the forest canopy. However, activity levels of 2 cluter-adapted species (eastern red/Seminole bats and eastern pipistrelles) did not differ above, within, or below the forest canopy. Despite classification as a clutter-adaptive species, evening bat activity was greater above rather than within or below the forest canopy. We believe our results highlight the importance of riparian areas as foraging habitat for bats in pine-dominated landscapes in the southeastern United States. Although acoustical surveys conducted below forest canopies can provide useful information about Species composition and relative activity levels of bats that forage in cluttered environments, our results showing activity above canopy suggest that such data may not accurately reflect relative activity of bats adapted to forage in more open conditions, and therefore may provide an inaccurate Picture of bat community assemblage and foraging habitat use.

We evaluated habitat selection of Sitka black-tailed deer in the central portion of the region during a winter with snowfall 43% above average using telemetry relocations Front 30 individuals that survived the winter. Ivlev indices for habitat selection within home ranges indicated that deer used less than expected, based on availability, north, cast, and west aspects, areas > 244-m elevation, noncommercial forests, and the low-timber volume stratum While Selecting South aspects, areas < 153-m elevation, and areas within 305 m of saltwater. Deer used less than expected moderately coarse-canopied forests in the medium- and high-timber volume strata typically found on north slopes while Selecting moderately fine-canopied forest in the high-timber volume stratum on south slopes. The lower than expected use of higher volume gap-phase old growth was likely because these were on north aspects where snow accumulated and persisted due to protection front maritime storms. Point relocations Suggested less use than expected in clearcuts < 41 years of age, while data from 7.2-ha error polygons showed deer were neutral to clearcuts. This suggests that if deer do avoid clearcuts they remain Close to the forest-clearcut edge. Of 4 habitat-mapping methods evaluated, the method that incorporated timber volume strata and a wind disturbance-related aspect bad greatest utility in identifying areas selected for Or used disproportionately little by deer during the deep snow winter. We found that deer exhibited marked changes in habitat use during deep snow conditions compared to a low snow winter, and we agree with previous researchers that providing habitats selected by deer during deep snowfall is all important consideration in Sitka black-tailed deer habitat management.

The formation of matrilineal social groups among female deer has been documented and management strategies have been proposed based on this well-developed social structure. Using radiocollared (n = 17) and hunter or vehicle-killed (n = 21) does, we examined spatial and genetic structure in white-tailed deer on a 7,000-ha portion of the Savannah River Site in the upper Coastal Plain of South Carolina, USA. We used 14 microsatellite DNA loci to calculate pairwise relatedness among individual deer and to assign doe pairs to putative relationship categories. Linear distance and genetic relatedness were weakly correlated (r = -0.08, P = 0.058). Relationship categories differed in mean spatial distance, but only 60% of first-degree-related doe pairs (full sibling or mother-offspring pairs) and 38% of second-degree-related doe pairs (half sibling, grandmother-granddaughter pairs) were members of the same social group based on spatial association. Heavy hunting pressure in this Population has created a young age structure among does, where the average age is < 2.5 years, and < 4% of does are > 4.5 years old. This - combined with potentially elevated dispersal among Young does - could limit the formation of persistent, cohesive social groups. Our results question the universal applicability of recently proposed models of spatial and genetic structuring in white-tailed deer, particularly in areas With differing harvest histories.

Methods and Results: Three previously published PCR primer sets and one set designed for this study were tested for their ability to produce amplification products for several pathogenic E. coli serotypes from whole cells as template. Two of the previously published primer sets were chosen for real-time PCR detection limit determination. The coneaeA and PEH detection limit of E. coli O157:H7 was 10(0) and 10(1) CFU rxn(-1) in sterile water respectively. To detect E. coli O157:H7 in sprout irrigation water, the water required dilution due to PCR inhibitors. The detection limit of the coneaeA and PEH was 10(1) and between 10(2) and 10(3) CFU rxn(-1) in diluted sprout irrigation water respectively. Conclusions: The primer set coneaeA was able to produce an amplification product from each E. coli serotype, except O128:H7 and most sensitive for real-time PCR detection of pathogenic E. coli in diluted sprout irrigation water. Significance and Impact of the Study: The necessity of a dissociation analysis to distinguish positive samples from those with fluorescence of random dsDNA generation for real-time PCR in a complex background was established.

Methods and Results: The Hagerstown soil was packed into boxes that were 10 cm deep, 30 cm wide and 100, 200 or 300 cm long. Grass was grown in boxes prior experiments. Same-length boxes were placed under rainfall simulator and tilted to have with either 2% or 4% slopes. Dairy manure was broadcast on the upper 30-cm section. Rainfall was simulated and runoff samples were collected and analysed for Cl, FC and total phosphorus (TP). Mass recovery, the concentration decrease rate k, and the ratio FC : TP showed that there was a consistent relationship between FC and TP in runoff. Conclusion: The FC and TP transport through simulated vegetated buffer strips were highly correlated. Significance and Impact of the Study: As a knowledge base on the effect of the environmental parameters on P transport in vegetated buffer strips is substantially larger than for manure-borne bacteria, the observed similarity may enhance ability to assess the efficiency of the vegetated buffer strips in retention of FC currently used as indicator organisms for manure-borne pathogens.

Methods and Results: Aliquots of rinsates, incubated in BBL Enterococcosel broth at 37 degrees C, 42 degrees C, or 45 degrees C for 24 and 48 h, were inoculated onto BBL Enterococcosel and M-enterococcus agar. Presumptive positive colonies were identified to species and tested for antibiotic resistance. Significant differences (P <= 0.05) were observed for media and temperature. More Enterococcus faecalis were isolated from M-enterococcus media and at 37 degrees C while more E. faecium were isolated from Enterococcosel agar and at 45 degrees C. The number of antibiotic-resistant E. faecalis and E. faecium were also affected by media and temperature. Conclusions: Culture conditions for enterococci affect the observed species and antibiotic resistance patterns and therefore should be carefully considered. Significance and Impact of the Study: This study indicates that media and temperature can influence the recovery and selection of enterococcal species and antibiotic susceptibility.

Methods and Results: An assay was developed to measure the inhibition of binding of recombinant norovirus-like particles (rNVLP) to HBGA in human saliva by porcine gastric mucin (PGM). The binding of rNVLP to HBGA could be inhibited by PGM in a dose-dependent pattern. Also, rNVLP could be captured effectively by PGM coated directly on plates and was detected by binding of polyclonal antibodies against rNVLP. Similarly, the binding of rNVLP to PGM could be inhibited effectively by HBGA in human saliva, and by Lewis b and Lewis d synthetic oligosaccharides (OS), but not inhibited effectively by an H3 OS or by purified bovine submaxillary gland mucin. Preincubation of rNVLPs with PGM completely inhibited their binding to human Caco-2 cells. Conclusions: PGM binds effectively to rNVLPs and competitively inhibits rNVLPs binding to human HBGA and Caco-2 cells. Significance and Impact of the Study: This is the first report of the binding of glycoproteins from animal gastric mucosa to human NVs. This study highlights the importance of further characterizing the NV incidence and infections in nonhuman animal hosts and the possibility that NV is a zoonotic disease.

Methods and Results: Transoligosaccharide propionate agar medium (TOS) modified by addition of mupirocin (50 mu g ml(-1)) and glacial acetic acid (1%, v/v), did not inhibit the growth of bifidobacteria compared with the control media yet inhibited the growth of Lactobacillus acidophilus, Lactobacillus gallinarum, Lactobacillus helveticus and Streptococcus gordonii. Conclusions: Addition of mupirocin (50 mu g ml(-1)) and glacial acetic acid (1%, v/v) to TOS (TOS-AM50), is an effective selective medium for isolation and enumeration of Bifidobacterium spp. from chicken caeca samples.

The data would be used as baseline information for reducing A. niger contamination in insect artificial diets. Methods and Results: Aspergillus niger was isolated from an insect artificial diet. Four concentration levels (i.e. 0, 1, 10 and 20 mu mol) of two fungicides (i.e. amphotericin B and itraconazole) were tested against A. niger under four a(w) levels (i.e. 0.994, 0.961, 0.921 and 0.859) adjusted by including 0, 12.5, 25 and 38% of glycerol in the medium mixture. Aspergillus niger growth was significantly reduced at low fungicide concentration (1 mu mol), and at reduced a(w). The spore germination was prevented with either higher fungicide concentration (> 10 mu mol), or low a(w) in the medium (a(w) < 0.921). The two ecological determinants (fungicides and a(w)) showed a significant impact on A. niger survival in the medium (P < 0.0001). Itraconazole is more effective than amphotericin B in controlling A. niger contamination in the agar medium. Conclusion: Adjustment of a(w) (with 12.5% of glycerol) in combination with 1 mu mol of itraconazole can effectively prevent A. niger growth in the SDA cultural medium. Significance and Impact of the Study: Aspergillus niger contaminations have frequently affected the quality of insects produced from mass rearing facilities. Low a(w) in combination with low fungicide concentration has the potential to become one of the most cost-effective management strategies to prevent A. niger contamination in insect artificial diets. The effect of fungicides and low a(w) in artificial diets on insect biology needs to be further examined. C1 USDA ARS, Biol Control Pests Res Unit, Stoneville, MS 38776 USA.

Methods and Results: Following exposure to 2.4% acetic acid for 7 min, S. enterica (serovars Mbandaka, Chester and Newport) cells were used to inoculate enrichment broths, phosphate-buffered saline (PBS), apple juice and fruit slices. Injured Salmonella cells resuscitated and regained the ability to form colonies on selective agar (Xylose-Lysine-Tergitol(R) 4) if they were incubated in lactose broth (LB), universal pre-enrichment broth (UPB) or buffered peptone water (BPW), but not in tetrathionate broth, PBS or apple juice. The resuscitation occurred at a significantly (P > 0.05) faster rate in UPB than in LB or BPW. The resuscitation also occurred on the surfaces of fresh-cut cucumber at 20 degrees C, but not at 4 degrees C. Conclusions: Acid-injured Salmonella cells resuscitated in nonselective enrichment broths at different rates, but not in selective enrichment broth, apple juice, PBS or on fresh-cut apple. Significance and Impact of the Study: Pre-enrichment of food samples in UPB prior to selective enrichment is recommended. Injured Salmonella cells have the ability to resuscitate on fresh-cut surfaces of cucumber when stored at abusive temperatures. C1 ARS, Eastern Reg Res Ctr, USDA, Wyndmoor, PA 19038 USA.

Methods and Results: Serial passage on ampicillin (beta-lactam) enriched modified Hsu-Shotts medium resulted in a F. columnare mutant that differed from the parent strain in colony morphology, whole cell proteins, adhesion and virulence. The mutant differed from its parent in virulence during immersion challenge, but not during injection challenge or generation of antibodies. Conclusion: Flavobacterium columnare exposure to ampicillin produces both resistance to that antibiotic and produces mutants that lack or have reduced adhesion characteristics and modified ability to adhere to fish tissue. Significance and Impact of the Study: This is the first description of an adhesion-defective mutant of F. columnare and the effects of altered adhesion on columnaris disease.

The increased productivity is believed to be due to increased infiltration of rainwater, since yield increases are normally only observed during drier years when water is limiting growth. If infiltration is significantly increased by renovating, then runoff should be decreased. Reductions in the amount of water running off pastures should result in reductions in phosphorus (P) and nitrogen (N) runoff. The objectives of this study were to determine the effects of pasture renovation on pasture hydrology (infiltration and surface runoff), nutrient (P and N) runoff, and forage production. Two sites located within the Piney Creek Basin in Arkansas, USA, were selected for this study. There were 3 fertilizer treatments for each soil; unfertilized, 8.97 Mg/ha of poultry litter (4 tons/acre), and 46,728 L/ha swine manure (5,000 gal/acre). Rainfall simulations were conducted after 1 day, 3 mo and 13 mo. after renovation in 2001 and 2002. The time to runoff was significantly longer on renovated land, the amount of infiltration was greater and the volume of runoff was less than that on unrenovated land. On average the amount of runoff was reduced by 45% with renovation, which translated into reductions in nutrient runoff of roughly the same magnitude. Total P loads in runoff were reduced by 43% with renovation; total N loads were reduced by 55%. Forage yields were not different on this first study, probably because the plots received simulated rainfall during dry periods of the year. Hence, forage yields were measured on a second study the following year. Pasture renovation significantly increased yields (27% higher on renovated plots). These data indicate that pasture renovation is a best management practice that can be used to reduce nutrient runoff from pastures, while improving productivity.

Anecdotal evidence suggests that these losses stem from animals particularly vulnerable to heat stress. A study was conducted to determine risk factors for heat stress in feedlot heifers. Two-hundred fifty-six feedlot heifers of four genotypes (32/genotype/year) were observed for 6-8 weeks in two consecutive summertime periods. As a measure of stress, respiration rates and panting scores were taken twice daily (morning and afternoon) on a random sample of 10 heifers/genotype. Weights, condition scores, and temperament scores were taken on a 28-day interval during the experiment. Health history from birth to slaughter was available for every animal used in this study. It was determined that stress level (respiration rate/panting score) was impacted by genotype (or color), a history of respiration illness, temperament, and degree of fatness. Daily weight gains were also impacted by genotype (or color), a history of respiration illness, and temperament. These results illustrate the sensitivity of respiration rate as an indicator of stress, and indicate that animals at risk for heat stress can be identified for possible applications of precision animal management.

Adaptations of these identification methods may be used to gain insights into animal performance and behavior for research, and ultimately as a production tool. An electronic identification system to monitor cattle behavior (BIDS) was designed and installed in a shade research facility constructed at USMARC. The goal of the system was to quantify performance and behavioral response in a production setting. The facility consists of 16 pens, containing eight animals per pen. Eight of the pens allow access to a shade structure, with the remainder having no shade access. The BIDS has been integrated into the bunk feeding system to monitor eating behavior. The system was developed for this research application to be low cost, rugged, and flexible. Antennas and electronic circuit boards were designed to allow individual eating locations and animals to be identified. Software was written to perform the control, reading, interpretation and logging of ear tag data. This paper details the design, construction, installation, and initial results of this research tool.

Water and two apple ciders, one from a cold press and the other from a hot press extraction, were the fluids used to study the heating characteristics. Volumetric flow rate and absorbed power were criteria in the evaluation. The microwave pasteurization system consisted of helical coils throughout a large cavity oven, which was shown to produce uniform and reproducible heating throughout the cavity. Fluid viscosity of water and cider was measured at temperatures between 20degreesC and 70degreesC to characterize the flow in helical coils based on the Dean number. Process lethality was verified based on inoculation of Escherichia coli 25922 in apple cider, in which the pasteurization process resulted in a 5-log(10) reduction.

Twenty-three morphological characters were measured from 161 specimens of Myotis. Differences among species for morphological characters were examined using analysis of variance and discriminant analysis. A bootstrap procedure was used to validate the final discriminant model using all six species. Differences were observed among species for all 23 characters measured in univariate tests, but the range of values for most species overlapped the range of other species. Bootstrap analyses indicated that our discriminant functions constructed using both external and cranial measures allowed correct identification of 99.4% of specimens examined. Discriminant models constructed using only cranial characters permitted correct identification of 96.9% of specimens examined. Univariate analyses were not reliable because variation within species prevented unambiguous identification of any species based on a single character. However, Myotis species in the southeastern United States can be distinguished with a high level of accuracy using multivariate techniques when a sufficient number of measurements are used.

Mating presumably occurs in these burrows but has never been directly observed in C. islagrande or any other thalassinidean. A variety of possible mating systems is suggested by those of other decapods, among which are examples of both internal and external sperm deposition, sperm competition among males, and male adaptations for paternity assurance. We used genetic markers to determine if clutches brooded by individual female ghost shrimp had been fertilized by multiple males. The two microsatellite loci we employed were sufficiently polymorphic to detect 95% of the occurrences of fertilization by two males. Among 40 ovigerous females collected from the Louisiana Isles Dernieres barrier island, eight (20%) carried egg masses for which more than two paternal alleles were detected, indicating fertilization by multiple males. In two cases of multiple paternity, alleles from one of the males were detected in only a portion of an egg mass. These observations suggest several, possibly novel characteristics of the mating system that can be further investigated. C1 Univ SW Louisiana, Dept Biol Sci, Lafayette, LA 70504 USA.

The only evolutionary aspect of marine parasites that has been studied in greater detail is coevolution. Much effort has gone into comparing evolution of some marine host groups, in particular various 'fishes', seabirds, and mammals, and of their parasites. The very detailed discussion of coevolution discusses these examples, but also points out that much work remains to be done: for most host and parasite taxa, information necessary to make inferences about coevolutionary patterns is insufficient. Much less is known about mechanisms of speciation. The author of the section on speciation and species delimitation stresses the importance of understanding 'what species are'. Such understanding is a prerequisite for addressing fundamental questions about biological processes and biodiversity. Various ways to delimit species are discussed, as are the few examples of studies of species delimitation and speciation in marine parasites.

Sures, Bernd BE Rohde, K TI Economic and environmental importance SO MARINE PARASITOLOGY LA English DT Article; Book Chapter AB Almost all (if not all) groups of marine animals including the various invertebrates and vertebrates are hosts to parasites. Parasites of these groups have been discussed by various authors in the four volumes edited by Kinne (1980-1985). This chapter is restricted to discussions of parasitic infections of the more important groups. Marine parasites are of very great ecological importance, as suggested by their great diversity, and by their often high prevalences and intensities of infection. However, very little is known about how they affect host populations in the oceans. An exception is the long-term study of salmon lice on Atlantic salmon not only in aquaculture but also in wild salmon populations, conducted because of the great economic importance of salmon. Mass mortalities caused by parasites have not been well documented for marine fish and invertebrates because of the large spaces in the oceans involved and the difficulties in monitoring such effects. Effects on marine birds are little understood and need much further study: mass mortalities of seabirds have been attributed to several causes but parasite examinations which could have revealed the role of parasites in the mortalities were not conducted. Effects on mammals such as whales are well documented, and hundreds of parasite species of mammals have been described; nevertheless, much needs to be done in this area as well. Much greater effort has gone into the study of parasite diseases in aquaculture, which is not surprising in view of the enormous and rising economic value of aquacultured fish, molluscs and crustaceans, estimated at many billions (109) of dollars annually. For example, the commercial value of cultured salmonid fishes alone in 2001 was around US$3.84 billion (US$7.44 billion for all finfish). Disease, and much of it resulting from parasites, is the single most important factor threatening the aquaculture industry. Beside these important negative aspects of marine parasites, this Chapter also discusses a more positive aspect of parasites: the use of parasites in pollution monitoring. Pollution may affect the composition of parasite communities, and some parasites store certain pollutants to a higher degree than their hosts; both these phenomena can be used for monitoring pollution.

The objectives of this study were (1) to determine the variability in methionine and tryptophan levels present in commercial maize inbred lines, (2) to characterize the genetic groups of commercial maize breeding germplasm for their methionine and tryptophan content, (3) to estimate general combining ability, specific combining ability, and reciprocal genetic effects for tryptophan and methionine content in this germplasm. Seventy-six inbred lines representing nine different genetic groups (B14/B73 - 5 lines, B14/B73/Iodent - 16 lines, B73 - 16 lines, 0H43/W153R - 6 lines, OH43/Iodent - 4 lines, Mo17 - 10 lines, European Flint - 8 lines, Plata - 6 lines, Unrelated - 5 lines) were evaluated. There was significant variability among the genetic groups and among the inbreds in some of the groups. A six-parent diallel mating design was completed with three parents selected for low metionine methionine and three parents selected for high methionine levels. A second diallel mating design was carried out with three parents selected for high tryptophan levels and three parents selected for low tryptophan levels. Analysis of the diallel crosses revealed significant general and specific combining ability effects, as well as reciprocal effects. These effects were of greater magnitude in the methionine diallel than in the tryptophan diallel. These studies suggest that methionine should respond better to selection than tryptophan. Maize breeders may be able to exploit these genetic effects to develop hybrids with elevated levels of tryptophan or methionine.

TI BREEDING FOR GRAIN QUALITY TRAITS SO MAYDICA LA English DT Review DE Amino acid balance; Fatty acid content; Amylose; Amylopectin; Mutants; Starch quality AB Plant breeders have been extremely Successful at improving the yield of maize. Grain quality has received less attention; however important advances have been made by breeders in this area as well. Maize with a wide range of compositions and fractions within the major grain components has resulted from breeders taking advantage of advances in biochemistry and genetics over the last fifty years. Breeding for grain quality provides end users With grain better suited to their needs. Maize with improved amino acid balance allows animal feed to be produced at a lower cost. Maize with altered fatty acid composition allows production of healthier vegetable oil. Maize With altered starch properties allows improvement of many products that rely on starch based gels, films and adhesives. Although mutants that impact these traits have been widely used, quantitative genetic approaches have also been successful when applied in long-term breeding programs. Two Successful approaches involve elements of both approaches, including the development of QPM based on the o2 Mutant with selection for improved kernel types and the development of high amylose maize based on the ae mutation with selection for increased amylose.

TI FLORETS & ROSETTES: MERISTEM GENES IN MAIZE AND ARABIDOPSIS SO MAYDICA LA English DT Article DE KNOX; Clavata; Meristems; Development; Maize; Arabidopsis AB Spectacular variety in plant form and adaptation can be seen throughout the Angiosperms. Even basal plants display complex morphologies as a result Of their genetic programs. Both the shoot and root arise from a fixed number of stem cells in the respective shoot and root apical meristems. These meristems are controlled by gene net-works that in turn are influenced by events that occur externally - a necessity due to the sessile nature of plants. Recent studies suggest chat the key regulatory pathways controlling maintenance of stem cell Populations and their transition into organs have largely been conserved since the divergence of monocots and dicots, 134 million years ago (WIKSTROM et al., 2001). The regulation of these path-ways may help explain differences in morphology between these two major plant subdivisions. Maize has comparatively large meristems and initiates a series of inflorescence meristems before producing determinant floral meristems. This expanded developmental program, along with abundant genetic resources, makes maize an ideal model for meristem studies. Several pathways have been elucidated in Arabidopsis that control organ generation and meristem maintenance. Maize orthologues have been identified that are conserved in protein sequence and function. Examples of these shared networks include those of the clavata and knox pathways. Evolution Of unique structures particular to the grasses, such as the spikelet, has also Occurred. In this case, no Arabidopsis orthologs have been identified, rather different genes have been co-opted for unique functions. Such examples are the adaptation of ERF proteins for spikelet meristem determinacy. We present a comparison of the regulation of key meristem pathways in the dicot model plant, Arabidopsis, and maize. C1 [Lunde, C.

Central to meeting the challenge of delivering viable decision support software, the USDA-ARS Great Plains Systems Research Unit (GPSRU), in a collaborative effort with Colorado State University (CSU), developed the Great Plains Framework for Agricultural Resource Management (GPFARM) DSS. The general purpose of GPFARM is to serve as a whole-farm/ranch DSS in strategic planning across the Great Plains. GPFARM runs on a field-by-field basis (with aggregation up to the whole-farm/ranch level), and provides production, economic and environmental impact analysis and site-specific database generation, from which alternative agricultural management systems can be tested and compared. Agricultural consultants and producers (both farmers and ranchers) were targeted as the primary users of GPFARM. User requirements were identified by an ARS customer focus group comprised of eastern Colorado farmers, ranchers, agricultural consultants, and NRCS and extension professionals. The GPFARM DSS is primarily composed of six major components: 1) a Microsoft(R) Windows-based graphical user interface; 2) Microsoft(R) Access databases containing soil, crop, weed, climate, equipment, chemical, and economic parameters; 3) an object-oriented modeling framework and science simulation model; 4) a stand-alone economic analysis tool; 5) a set of analysis tools including a multicriteria decision making module, an output visualization module, and summary report tables and graphs; and 6) a web-based information system. Thus, GPFARM is unique in that it brings together the above suite of decision support tools integrated across a whole-farm/ranch system. The idea for developing GPFARM was conceptualized in the late 1980's. Actual GPFARM development occurred from the early 1990's to 2003, ending with the current version 2.6. Despite a reasonable level of producer involvement in the requirements analysis, development, and evaluation phases of GPFARM, it can be argued that the rate of adoption has been slow compared with the rate predicted for it over a decade ago at development initiation. The successor to GPFARM (iFARM - integrated Farm and Ranch Management) is currently under development. Can we use our experiences from the GPFARM project to improve iFARM? In this paper, we first provide a brief overview of the GPFARM DSS. We then discuss the lessons learned (e. g., successes and failures) in over a decade of agricultural DSS development. A summary of conclusions resulting from discussion and critical analysis of the GPFARM project include: It is important that the DSS development process includes careful evaluation of the scope of the DSS in relation to the human and fiscal resources available (e. g., assessment of personnel available for developing, evaluating, implementing, and maintaining a DSS that matches the scope, scale, and complexity of the project). Formal project management and software engineering protocols and tools can aid in this regard. Careful attention to the intended target user group(s) is needed by: 1) matching the proposed technology appropriately with the user, and 2) gathering input from a broad spectrum of potential users when performing a requirements analysis. Simpler tools or database information generated from simulation analyses of alternative management options may have been more appropriate for delivery to producers and consultants at this stage in time. The capability to rapidly update major components (e. g., simulation model, databases) and address current questions or problems in the system is an absolute necessity - the GPSRU has recently developed an Object Modeling System (OMS) for this purpose. In addition, an appropriate compromise between scientific rigor and simplicity is essential for critical DSS components to ensure overall quality of the product (e. g., crop and forage simulation model response to environmental stresses; N and water balance response to management).

The Great Plains Framework for Agricultural Resource Management (GPFARM) DSS is a strategic planning tool for farmers, ranchers, and agricultural consultants that incorporates a science simulation model with an economic analysis package and multi-criteria decision aid for evaluating individual fields or aggregating to the entire enterprise. The GPFARM DSS is currently being expanded to include 1) better strategic planning by simulating a greater range of crops over a wider geographic range and management systems, 2) incorporating a tactical planning component, and 3) adding a production, environmental, and economic risk component. The plant growth component within the science simulation model is subdivided into separate submodels for crops and rangeland forage. User requirements have determined that the DSS must be easy to use in terms of setup, and therefore little parameterization or calibration for a specific site can be required. Based on evaluation of both the crop and rangeland forage growth module of GPFARM, improvements are needed to more accurately simulate plant responses to varying levels of water availability. This paper presents our approach and some preliminary results for improving the plant growth models. Our approach is based on using the stand-alone plant growth model derived from the Wind Erosion Prediction System (WEPS), which is based on the EPIC plant growth model. Steps that should improve the plant growth models include 1) incorporate modifications from work done to other models that are based on the EPIC plant growth model (e.g., GPFARM; Water Erosion Prediction Project, WEPP; ALMANAC; and Soil and Water Assessment Tool, SWAT), and 2) thoroughly evaluate how the plant processes are represented in these models. Deficiencies in adequately simulating plant growth responses to water availability can fall under two general categories: inadequate quantification of the process or omission of a needed process in the model. High priority needs identified to date include: 1) seedling emergence, 2) phenology, 3) biomass generation, 4) biomass partitioning, 5) root growth, and 6) plant stress factors. Initial work has created stand- alone submodels for predicting seedling emergence (as a function of soil water and thermal time) and phenology (by predicting specific growth stages and responses to different levels of soil water availability). Evaluation of alternative approaches for generating biomass (e.g., radiation use efficiency, transpiration use efficiency, plant growth analysis), biomass partitioning (e.g., modifications to generating LAI and partitioning coefficients partly based on better phenology prediction), and stress factors (e.g., single-most limiting, additive, multiplicative) is underway. We envision that these modifications and enhancements should improve model responses to varying levels of soil water availability. C1 [McMaster, G. S.; Ascough, J. C., II; Edmunds, D. A.; Andales, A.

It is important to evaluate how a model responds to changes in its inputs as part of the process of model development, verification, and evaluation. There are several techniques for sensitivity analysis used by practitioners and analysts in numerous fields. For example, sensitivity analysis methods are commonly built-in features of a particular software tool, e. g., Crystal Ball or @Risk. However, there are other sensitivity analysis methods, including those used outside of the natural resources field, applicable to integrated system models. In this paper, we concentrate on qualitatively evaluating four sensitivity analysis methods: 1) Fourier Amplitude Sensitivity Test (FAST), 2) Response Surface Method (RSM), 3) Mutual Information Index (MII), and 4) the methods of Sobol'. For sensitivity analysis of natural resource models, the FAST and Sobol' methods are particularly attractive. These methods are capable of computing the so-called "Total Sensitivity Indices" (TSI), which measure parameter main effects and all of the interactions (of any order) involving that parameter. Additional recommendations resulting from our evaluation include: Sensitivity analysis should be used prior to model development, during model development, and when the model is applied to a specific problem. Sensitivity analysis provides useful risk insights, but alternative approaches are also needed to understand "which" parameters show up as important and "why" they show up as important. Sensitivity analysis can be a valuable tool in building confidence in the model and in the embedded computer codes. In spite of current advances, the state-of-the-science has not matured to the point of quantitatively deriving significance from sensitivity analyses as input to final decision-making. The use of global sensitivity methods is emphasized herein. Many methods currently in use have some sort of global aspect (though not explicitly recognized), in particular, variance-based sensitivity measures (e. g., FAST and Sobol') are concise and easy to understand and communicate. There is a concern that uncertainty and sensitivity analysis methods could be incorrectly used to make a case for or against a project. Therefore, there is a need to develop guidance documents (with expert involvement or endorsement) that will provide sensitivity analysis practitioners with knowledge of what is available, and the context of where the methods can be used (i.e., when to use them, and how to use them). Recent developments illustrate the tremendous need for implementing quantitative sensitivity analyses. Furthermore, a gap remains in public education of the utility and implementation of sensitivity analysis methods in the decision-making process. Issues addressed in this paper pertaining to the application of sensitivity analysis in natural resource modeling include: 1) criteria for sensitivity analysis methods applied to natural resource models, 2) identification of several promising sensitivity analysis methods for application to natural resource models, and 3) needs for implementation and demonstration of sensitivity analysis methods. As stated above, it is our goal that this paper will eventually lead to creation of a guidance document for assisting practitioners with regard to the selection of sensitivity analysis methods, and their application, interpretation, and reporting. The overall guidelines should not be too restrictive, but instead provide useful boundaries and principles for selecting, using, and interpreting results from sensitivity analysis methods.

Primers designed for highly conserved regions of candidate genes can be used to amplify DNA from plants in the collection. These amplified DNA fragments of identical length are turned into useful markers by assaying sequence differences by CAE-SSCP analysis. Sequence differences affect the electrophoretic mobility of single-stranded DNA under non-denaturing conditions. By collecting the mobility data for both strands assayed at two temperatures, alleles can be defined by mobility alone. For a germplasm collection with an unknown number of alleles at a locus, such mobility data of homozygotes can be used to determine the number of unique alleles without the necessity of cloning and sequencing each allele.

Non-beet-infecting isolates of BWYV found particularly within Europe have now been re-named Turnip yellows virus (TuYV). Species-specific antibodies are unavailable, but the viruses can be distinguished by RT-PCR using primers specifically designed to the 5' end of their respective genomes. Physical properties: The isometric virus particles are approximately 26 nm in diameter and the genome consists of a single strand of positive sense RNA that utilizes almost all known plant virus gene expression strategies (initiation bypass, translational frameshifting and readthrough, synthesis of subgenomic RNA and proteolytic processing). Host range: Many members of the Chenopodiaceae are susceptible, including commercial crops of sugar beet (Beta vulgaris), red beet and spinach. Experimental hosts include Montia perfoliata, Nicotiana benthamiana and Arabidopsis thaliana. Symptoms: Sugar beet infected with beet poleroviruses show patches of chlorosis on the older leaves 4-6 weeks post-infection; these areas expand until the whole leaf becomes yellow and older leaves then tend to thicken and become brittle. Transmission: Beet poleroviruses are transmitted in a persistent (circulative, non-propagative) manner by several different aphid species, Myzus persicae being the most important vector.

However, divergence is present among these three fluorescent pseudomonads, yielding 'suites' of species-specific genes that may provide the genetic basis for adaptation to an ecological niche and lifestyle. For DC3000,1053 genes located on the chromosome were specific to DC3000 and not present in PAO1 or KT2440. The majority of these DC3000-specific genes either lack a known function or are mobile genetic elements. However, these genes do share features among themselves such as association with regions of atypical trinucleoticles, unusual G+C content and localization within large tracts of DC3000-specific sequence, suggestive of lateral gene transfer events. Indeed, a comparison of syntenic blocks among these three complete Pseudomonas genomes revealed that a substantial portion (533) of the DC3000-specific chromosomal genes (1053) were located in lineage-specific regions (defined as being larger than 2 kb and enriched in mobile genetic elements and/or genes specific to DC3000 in this three-way comparison). A large proportion of mobile genetic elements (199 of 318 genes; 63%), which are highly enriched in DC3000, were present within such regions. Similarly, most of the genes encoding type III secretion system virulence effectors were located in lineage-specific regions. Consistent with the plasticity of the DC3000 genome, a putative. chromosomal inversion mediated by identical copies of ISPsy6 involving 2838 kb (44%) of the DC3000 genome was detected. These data suggest that a substantial portion of the differentiation of DC3000, a plant pathogen, from an animal pathogen and a soil inhabitant has involved transfer of a large number of novel genes coupled with amplification of mobile genetic elements.

Coronatine acts as a virulence factor in Arabidopsis and mutants insensitive to coronatine are resistant to Pst and have higher levels of salicylic acid (SA). In this work we used the SA-deficient lines NahG and sid22 to determine if coronatine acts directly as a virulence factor or indirectly by SA suppression. Using coronatine-deficient Pstmutants we demonstrated that the lack of coronatine compromises Pst virulence in both wild-type and SA-deficient Arabidopsis. Thus, the action of coronatine is not due to SA suppression. Rather, SA-independent jasmonate-responses are the most likely mechanism for its action.

Thirteen distinct DNA fingerprint groups or genotypes were identified among the 43 isolates. Twenty-four isolates belonging to VCG 1 produced identical DNA fingerprints and included isolates from the United States and Japan. Four other DNA fingerprint groups had multiple isolates sharing identical fingerprints corresponding to VCGs 2, 3, 12 and 13. Eight of the 13 fingerprint groups corresponding to VCGs 4-11 were represented by a single isolate with a unique fingerprint pattern. These results provide further confirmation that the pAF28 probe can distinguish VCGs of species within Aspergillus section Flavi based on DNA fingerprint patterns and that tire probe call be used to estimate the number of VCGs in a sample population. Most of the A. caelatus isolates produced fewer restriction fragments and weakly hybridized with the repetitive DNA probe pAF28 compared to hybridization patterns obtained with A. flavus, suggesting less homology of tire probe to A. caelatus genomic DNA.

Species recognition in Beauveria is difficult due to a lack of taxonomically informative morpholopy. This has impeded assessment of species diversity in this genus and investigation of their natural history. A gene-genealogical approach was used to investigate molecular phylogenetic diversity of Beauveria and several presumptively related Cordyceps species. Analyses were based oil nuclear ribosomal internal transcribed spacer (ITS) and elongation factor 1-alpha (EF1-alpha) sequences for 86 exemplar isolates front diverse geographic origins, habitats and insect hosts. Phylogenetic trees were inferred Using maximum parsimony and Bayesian likelihood methods. Six well supported clades within Beauveria, provisionally designated A-F, were resolved in the EF1-alpha and combined gene phylogenies. Beauveria bassiana, a ubiquitous species that is characterized morphologically by globose to subglobose conidia, was determined to be non-monophyletic and consists of two unrelated lineages, clades A and C. Clade A is globally distributed and includes the Asian teleomorph Cordyceps staphylinidaecola and its probable synonym C. bassiana All isolates contained in Clade C are anamorphic and originate from Europe and North America. Clade B includes isolates of B. brongniartii, a Eurasian species complex characterized by ellipsoidal conidia. Clade D includes B. caledonica and B. vermiconia, which produce cylindrical and comma-shaped conidia, respectively. Glade E, from Asia, includes Beauveria anamorphs and it Cordyceps teleomorph that both produce ellipsoidal conidia. Glade F, the basal branch in the Beanveria phylogeny includes the South American species B. amorpha, which produces cylindrical conidia. Lineage diversity detected within clades A, B and C suggests that prevailing morpho logical species concepts underestimate specics diversity within these groups, Continental endemism of lineages in B. bassiana s.l.

Permutation tests indicate that host association is essentially random in both B. bassiana s.l, clades A and C, supporting past assumptions that this species is not host specific. In contrast, isolates in clades 11 and D occurred primarily oil coleopteran hosts. although sampling ill these clades was insufficient to assess host affliation at lower taxonomic ranks. The phylogenetic placement of Cordyceps staphylinidaecola/bassiana, and C. scarabaeicola within Beauveria corroborates prior reports of these connections. These results (establish it phylogenetic Framework for further taxonomic, phylogenetic and comparative biological investigations of Beauveria and their corresponding Cordyceps teleomorphs.

Aflatoxigenic fungi commonly invade peanut seeds during maturation, and the highest concentrations of aflatoxins are found in damaged seeds. A laboratory procedure was developed in which viable peanut seeds were wounded and inoculated with field soil containing natural populations of fungi, then incubated tinder different conditions of seed water activity and temperature. Densities of Aspergillus section Flavi in soil used for inoculating seeds were low relative to the total numbers of filamentous fungi (< 1%). Aspergillus species from section Flavi present in soil included A. flavus morphotypes L and S strains, A. parasiticus, A. caelatus, A. tamarii and A. alliaceus. Wounding was required for high incidences of fungal colonization; viability of wounded seeds had little effect oil colonization by Aspergillus species. Peanut seeds were colonized by section Flavi species as well as A. niger over broad ranges of water activity (0.82-0.98) and temperature (15-37 C), and the highest incidences of seed colonization occurred at water activities of 0.92-0.96 at 22-37 C. A. parasiticus colonized peanut seeds at lower temperatures than A. flavus, and cool soil temperatures relative to Winperatures of aerial crop fruits might explain why A. parasiticus is found mostly in peanuts. Other fungi, dominated by the genera Penicillium, Fusarium and Clonostachys, colonized seeds primarily at water activities and temperatures suboptimal for section Flavi species and A. niger Eupenicillium ochrosalmoneum frequently sporulated on the conidial heads of section Flavi species and showed specificity for these fungi. The inoculation of wounded viable peanut seeds with soil containing natural populations of fungi provides a model system for studying the infection process, the interactions among fungi and those factors important in aflatoxin formation.

The fungus functions as an endophyte, a fungal/host interaction beneficial to the growth of some plants. At other times, the fungus may function as a mycotoxin producing pathogen. The advantages and/or disadvantages of the endophytic relationship must be established in order to target appropriate sites for controlling diseases and mycotoxins in maize. One possibility could be to ensure seed maize is fungal free prior to planting. Reciprocal inoculations were made with two fungal isolates on seed of two maize genotypes. Yield was measured at harvest by ear and seed characters and vegetative growth at one-month intervals for plant survival, height, weight and stem diameter. Yield and vegetative growth differed among mature plants only once based on seed inoculation status. In 1998, plant weight was reduced and seed weight per ear was increased for the dent maize, GT-MAS:gk, grown from F. verticillioides RRC 374-inoculated seed compared to other seed treatments. Most vegetative characters were reduced at the first collection for Silver Queen plants grown from F. verticillioides-inoculated seed in 1997 and 1999, but not in 1998. However, no significant differences occurred among mature Silver Queen plants during any of the three growing seasons. In conclusion, yield and vegetative growth of mature maize plants grown from F. verticillioides-inoculated seed were equal to or greater than plants grown from non-inoculated seed under south Georgia field conditions during 1997, 1998, and 1999.

Ectomycorrhizal roots were sampled beneath fruitbodies of C. helodes and G. monticola from two homogeneous A. acuminata forest sites located in Tucuman and Catamarca Provinces in Argentina. C. helodes ectomycorrhizas showed a thick white to beige mantle exuding a milky juice when injured, were bluish toward the apex, and had hyphal strands in the mantle. G. monticola ectomycorrhizas showed some conspicuous features like highly differentiated rhizomorphs, inflated brown cells on the mantle surface, and hyaline and brown emanating hyphae with dolipores. Restriction fragment length polymorphism analysis of the nuclear rDNA internal transcribed spacer provided a distinctive profile for each of the collections of fruitbodies and the mycorrhizal morphotypes.

We compared plant communities in the Allegheny National Forest (ANF) on boulder tops and the forest floor to test the hypothesis that large boulders serve as refugia for plants threatened by deer herbivory. Five of the ten most common woody species (hemlock, Tsuga canadensis L., mountain maple, Acer spicatum Lam., red maple, A. rubrum L., striped maple, A. pensylvanicum L., and yellow birch, Betula alleghaniensis Britton) occurred at much higher densities on boulders than in randomly selected areas of the same size adjacent to these boulders on the soil surface. We never encountered any individuals of hemlock, mountain maple, or red maple on the forest floor. Total woody species density (excluding root suckers of beech, Fagus grandifolia Ehrh.) was nearly three times higher on the boulders. Woody species richness and evenness, as well as forb and shrub cover and richness, were also much greater on boulders. Our results strongly suggest that overbrowsing by deer can dramatically reduce tree regeneration and diversity as well as reduce forb and shrub abundance in the ANF. Furthermore, understory plant communities are now dominated by species that are known to be unpalatable or tolerant of deer browse, particularly beech, grasses, and ferns (Dryopteris carthusiana Vill. and Thelypteris noveboracensis L.). The primary alternative explanation is that conditions on the surface of boulders are superior for numerous woody and herbaceous species. Although we cannot rule this out, we consider this alternative improbable because of the poor nature of these habitats. Because deer are reducing the diversity and abundance of both woody and herbaceous species, we conclude that deer are damaging the very nature of these hardwood forests. Furthermore, our findings suggest that boulders could serve as an inexpensive bioassay of deer impact on vegetation whenever they are common and large enough. Boulders may also overcome the problem associated with the ghost of herbivory past, whereby plant species that would respond to the reduction of herbivores are absent because they have been driven to very low abundance or local extirpation. Our findings suggest that sampling the surface of boulders circumvents this problem because the vulnerable species were never subjected to sustained browsing on these refugia; consequently, these areas may represent typical levels of abundance of these vulnerable plant species.

Perhaps one of the most challenging aspects of modern life is our increasing ability to communicate, especially in the developed countries. This communication has brought an increased sense of connectedness but also made people more aware of the occurrence and consequences of natural disasters. In this paper we explore the potential for changes in frequency and magnitude of weather-related natural disasters and some of their connections to climate change and variability. Although changes in climate may have great consequence, increasing climate variability may become the most immediate challenge for world society. Both observations and simulation models show that as the potential for climate variability increases, natural disasters have become more frequent and of deeper economic impact. In areas of the world where these devastating events appear to occur and then quickly reoccur in a different guise, the sharing of information and resources becomes a pivotal issue for collective security. New technologies can help us understand these events and prepare for them. New social institutions may also be needed to cope with these issues on a global scale.

These natural disasters caused severe hardship not only on the agriculture sector of society, but also on the entire socio-economic infrastructure. Until recently, governments and relief agencies responded to a drought disaster from a crisis perspective in a purely reactive approach. However, a comprehensive disaster management approach has emerged over the past decade, shifting from reactive relief to proactive risk management. Risk management is based on preparedness and mitigation measures. Interagency collaboration led to the development of a coordinated national drought policy.

In the past decade, fire occurrence and area of surface burned has increased dramatically. This increase in wildland fire frequency and intensity has been driven by climate variability and in some countries, worsened by fuel management policies. Many areas that have been burned are in remote areas of the world where collection of information on fires is either difficult or impossible on the ground. Satellite remote sensing has been applied to this problem with some remarkable successes in locating large fires, mapping the areas burned, and tracking smoke plumes. For smaller fires, pixel size limitations have led to use of aircraft based sensor development. To understand fire ecological consequences, parameters such as fire intensity, fuel consumed, and heat release rate to atmosphere must be understood. In parts of the Southwest Pacific Region, the potential for fire occurrence is exacerbated by lack of infrastructure common to more developed areas. The use of remote sensing, geographic information systems, and computer models will allow fires to manage to lower risks. C1 USDA, Forest Serv Res & Dev, WFWAR, Washington, DC 20250 USA.

(Lepidoptera: Olethreutidae) employ a pheromone that attracts or arrests conspecifics seeking pupation sites. Such intraspecific communication signals are important cues for illicit receivers such as parasitoids to exploit. We tested the hypothesis that the prepupal C. pomonella parasitoid Mastrus ridibundus Gravenhorst (Hymenoptera: Ichneumonidae) exploits the larval aggregation pheromone to locate host prepupae. In laboratory olfactometer experiments, female M. ridibundus were attracted to 3-day-old cocoons containing C. pomonella larvae or prepupae. Older cocoons containing C. pomonella pupae, or larvae and prepupae excised from cocoons, were not attractive. In gas chromatographic-electroantennographic detection (GC-EAD) analyses of bioactive Porapak Q extract of cocoon-derived airborne semiochemicals, ten compounds elicited responses from female M. ridibundus antennae. Comparative GC-mass spectrometry of authentic standards and cocoon-volatiles determined that these compounds were 3-carene, myrcene, heptanal, octanal, nonanal, decanal, (E)-2-octenal, (E)-2-nonenal, sulcatone, and geranylacetone. A synthetic 11-component blend consisting of these ten EAD-active compounds plus EAD-inactive (+)-limonene (the most abundant cocoon-derived volatile) was as effective as Porapak Q cocoon extract in attracting both female M. ridibundus and C. pomonella larvae seeking pupation sites. Only three components could be deleted from the 11-component blend without diminishing its attractiveness to M. ridibundus, which underlines the complexity of information received and processed during foraging for hosts. Mastrus ridibundus obviously "eavesdrop" on the pheromonal communication signals of C. pomonella larvae that reliably indicate host presence.

Recently, new strains of N. coenophialum have been isolated from wild tall fescue and artificially inoculated into elite tall fescue cultivars. These strains produce low to nil levels of ergot alkaloids and are referred to as non-ergot strains. Our objective was to determine whether non-ergot strains of the endophyte confer the same level of resistance to Pratylenchus spp. as the endemic strain in tall fescue. In a glasshouse experiment, nematode resistance was compared in two fescue cultivars (Jesup and Georgia 5) infected with either the endemic strain (E(+)), or two non-ergot strains, AR542 and AR584. An additional non-ergot strain, AR514, was tested only in cv. Jesup. Cultivars Georgia 5 and Jesup without endophytes (E(-)) were used as controls. The endophtye status of the plants was confirmed and then three plants per cultivar/endophyte combination were transplanted into 10 cm square pots. The pots were inoculated with a mixed culture of Pratylenchus zeae and P. scribneri in the first trial and a pure culture of P. scribneri in the second trial of the experiment. After 8 weeks, the number of nematodes within the roots from each pot was determined. Numbers of Pratylenchus spp. in either cv. Georgia 5 or cv. Jesup containing the non-ergot strain AR542 were not different from numbers in E- plants. AR514 also did not confer resistance to the nematodes in cv. Jesup. By contrast, the non-ergot strain AR584 appears to confer resistance to Pratylenchus spp. in cv. Georgia 5, but not in cv. Jesup; however, the level of resistance in cv. Georgia 5 was less than the resistance conferred by the endemic endophyte. Genetic differences between the two tall fescue cultivars may affect growth of the endophyte or production of a nematode toxin or deterrent by the endophyte. As only a small subset of endophyte strains has been tested, we are screening additional non-ergot strains for resistance to P. scribneri. C1 ARS, USDA, Tifton, GA 31793 USA.

Chitinolytic bacteria were evaluated as potential biological control agents of the root-knot nematode, Meloidogyne incognita, on tomato. After transplantation of seedlings into pots containing soil amended with chitin compost, chitin broth, or respective controls, soil was inoculated with nematode eggs and infective second-stage juveniles (J2). Samples taken at 4, 6 and 8 weeks after inoculation indicated that fresh weights of plants did not vary between treatments or between treatments and controls. The gall index was lower in the plants grown in the chitin-amended soil at each time point. Activities of soil chitinase and beta-1,3-glucanase were greater in those soils amended with chitin compost and chitin broth. Gall index of tomato root was negatively correlated with soil chitinase activity. Activities of tomato root chitinase and beta- 1,3-glucanase were higher in plants growing in non-chitin-amended soil at 6 and 8 weeks after nematode infestation. Chitinase activity in tomato root was positively correlated with the gall index of tomato root. The results indicate the potential of chitinase producing bacteria to alleviate nematode parasitism in important vegetable crops.

Multiple displacement amplification (MDA) was assessed for whole genome amplification of crude DNA from several Meloidogyne species. MDA produced microgram quantities of template that resulted in successful amplification of the ribosomal internal transcribed spacer (ITS1) and 28S D2-D3 expansion regions, producing PCR results that were comparable to template generated by the single nematode smash method. MDA greatly improved degenerate primer PCR of single-copy Hsp90, a gene which is more sensitive than multi-copy ribosomal genes to limited DNA template. MDA should expand the number of molecular analyses possible for single nematodes. MDA will also be useful for archiving DNA from valuable specimens and provide a way for laboratories to share identical genetic material for nematode diagnosis.

Field and growth chamber studies were conducted to determine the survivability of the nematode in fallow nursery soil. The population density of L. americanus decreased rapidly in the upper 15 cm of soil in fallow field plots during the first 101 days and the nematode was not detected after 263 days. Bioassays subsequently failed to detect the nematode in the upper 30 cm of soil in fallow plots on days 263 and 365. Population densities also decreased rapidly in fallow soil during the initial 130 days of the growth chamber study and the nematode was not detected at days 334 and 427, or in subsequent bioassays. Longidorus americanus does not survive well in the upper 15-30 cm of nursery soil in the absence of a host, and the use of fallow may be an acceptable alternative to pesticides for the management of this nematode.

Rhabditis rainai n. sp. is a hermaphroditic species with an unusual prerectum. four denticles per glottoid swelling, enlarged posterior stoma, three paired lip sectors, protruding posterior anal lip, and five ridges in the hermaphrodite lateral field. Males generated from starved bacterial cultures have three lateral field ridges and a notched peloderan bursa with only eight rays. Male spicules are distinctive with a round but truncated head, constricted neck, narrow shoulders, nearly straight blade with distal tenth upturned, and rounded tips supporting a curved ventral arch. Males of LKC20 were mated successfully with hermaphrodites cultured from a Fiji Islands soil (isolate PS1191). In subsequent crosses, male progeny were fertile as expected for conspecific populations. Differences in morphometrics of cultured specimens that were heat-killed or fixed is demonstrated. Rhabditis rainai n. sp. was compared to R. blumi and R. adenobia, but does not fit clearly within the current subgenera of Rhabditis or genera of Rhabdifidae. Nematode-termite relationships and possible origin of R. rainai n. sp. with Formosan subterranean termites from Southeast Asia are discussed. C1 USDA ARS, BARC, Nematol Lab, Beltsville, MD 20705 USA.

This issue is examined further in this paper, particularly the effect that certain types of transformations, such as aggregation and sampling, may have on the identification of the dynamics of the underlying system. First, we investigate the dynamics of daily streamflows for two rivers in Florida, one with strong surface and groundwater storage contributions and the other with a lesser basin storage contribution. Based on estimates of the delay time, the delay time window, and the correlation integral, our results suggest that the river with the stronger basin storage contribution departs significantly from the behavior of a chaotic system, while the departure is less significant for the river with the smaller basin storage contribution. We pose the hypothesis that the chaotic behavior depicted on continuous precipitation fields or small time-step precipitation series becomes less identifiable as the aggregation (or sampling) time step increases. Similarly, because streamflows result from a complex transformation of precipitation that involves accumulating and routing excess rainfall throughout the basin and adding surface and groundwater flows, the end result may be that streamflows at the outlet of the basin depart from low dimensional chaotic behavior. We also investigate the effect of aggregation and sampling using series derived from the Lorenz equations and show that, as the aggregation and sampling scales increase, the chaotic behavior deteriorates and eventually ceases to show evidence of low dimensional determinism.

To evaluate them, a simplified method for comparing their ammonia control properties was developed. Ammonia levels from water treated with five different zeolites were effectively measured and compared with two different inexpensive total ammonia nitrogen (TAN) test kits using the same procedure. I found that 10 g of a zeolite added to and stirred in an ammonia solution (0.1 g of ammonium sulfate dissolved in 1 L water) for 20 min produced TAN levels within the readable ranges for the Hach Model NI-8 and NI-SA ammonia nitrogen test kits; a 1:6 dilution of the ammonia test solution was made just before the TAN analysis. The TAN readings after the addition of the five zeolites ranged from 1.2 to 2.6 mg/L (multiplying by 7 to get actual TAN readings is not necessary to compare zeolites) for the Model NI-8 kit. The Model NI-SA kit gave the same relative results but had readings that were 0.5-0.7 mg/L lower; in the case of these kits the obtained precision was more important than their accuracy.

Anesthetic efficacy, recovery time, and the effects of AQUI-S on routine measures of stress were compared with similar measures in a group of fish sampled prior to anesthesia (preanesthesia [PA] group) and a group anesthetized with 100 mg tricaine methanesulfonate (TMS)/L. On average, all the fish lost equilibrium at 8.0, 3.9, and 3.7 min when anesthetized in 20, 40, and 60 mg AQUI-S/L, respectively. Fish anesthetized with TMS lost equilibrium at 4.5 min. Recovery time in freshwater was 2.1, 2.8, and 5.3 min for fish anesthetized in 20, 40, and 60 m,-/L AQUI-S, respectively. Recovery time after TMS anesthesia was 1.7 min. Short-term (24-h) survival was 100% for all treatments, and long-term (21-d) survival ranged from 87.5% for TMS-anesthetized fish to 98.8% for fish anesthetized in 40 mg/L AQUI-S. All anesthetic treatments significantly reduced (P < 0.05) plasma cortisol levels relative to PA fish, and circulating cortisol was lower (P < 0.05) in all AQUI-S-anesthetized fish than in TMS-anesthetized fish. Plasma glucose concentrations were significantly lower (P < 0.05) in fish anesthetized with 40 mg/L AQUI-S than in PA and TMS-treated fish after both anesthetization and recovery. Plasma lactate and chloride concentrations were not reduced (P > 0.05) in any treatment compared with the levels in PA fish. Fish anesthetized with 40 mg/L AQUI-S had lower (P < 0.05) plasma lactate levels after recovery than TMS-anesthetized fish, and plasma chloride levels were significantly lower (P < 0.05) immediately following AQUI-S anesthesia at all concentrations than in fish anesthetized with TMS. Anesthesia did not affect (P > 0.05) postrecovery plasma chloride concentrations. Overall, AQUI-S exhibited efficacy as an anesthetic for mature channel catfish and demonstrated stress-reducing properties during handling procedures.

In the field, delta-shaped traps baited with 6 virgin females caught males exclusively, with the most abundant catches on the ground as compared to those at 1 and 2 m. Most males were captured at 1100 hours and males remained in the vegetation under the trees throughout the day. Sweep netting revealed that conspecifics mate in the vegetation under orchard trees in the morning hours, and females move from the ground to the orchard canopy to oviposit at. 1000 hours. Gas chromatographic-electroantennographic detection (GC-EAD) analyses indicated the presence of an electrophysiologically active compound in solid phase microextraction (SPME) effluvial collections and pheromone gland extractions from virgin females.

The objective of this research was to determine how past agricultural practices and management history have affected soil properties in three forested areas in southeast New Hampshire. Four transects were established on each site, and moisture content, pH, microbial biomass, O horizon thickness, and A horizon organic matter content were measured. O and A horizon pH values increased with increasing intensity of past management, possibly due to past burning and liming associated with agriculture. A horizons were thicker and contained more soil organic matter at the sites that had been used for agriculture and O horizons were thickest at the least disturbed site, indicating that O and A horizons have different responses to past disturbance intensity. These results suggest that soil properties at these three sites still reflect their agricultural history, even more than 100 years after agricultural abandonment and reforestation.

Recent published research has documented the importance of still-water habitats as foci of bat flight activity. To better understand and document habitat use in southern New England, we used the AnaBat II acoustical monitoring system to assess species composition and relative levels of summer flight activity. Active acoustic surveys were conducted in six habitat types on the Quabbin Reservation in central Massachusetts in 2003 and 2004. Bat flight activity, as measured by numbers of echolocation call sequences, was high, with an average of 24 search-phase and 4 feeding-buzz calls per 20-minute survey period. Myotis lucifugus (little brown bat) was the most commonly recorded species. Bat flight activity was high over all still-water habitats, but greatest over large ponds. Large-bodied bats, such as Eptesicus fuscus (big brown bat), were recorded more often in open, structurally uncluttered habitats. Of the small-bodied bats, little brown bats were ubiquitous, whereas Myotis septentrionalis (northern myotis) was most common in structurally cluttered habitats of seasonal forest (vernal) pools and along forest streams. Generalized habitat associations among the bat species we recorded are similar to those reported for other New England forest sites. The Quabbin Reservation is an excellent site to continue examining bat-habitat relationships because of the abundance and diversity of aquatic habitats, in both cluttered closed-canopy and uncluttered open-canopy settings.

Forest managers can use information about broom development to balance competing objectives of providing wildlife habitat and maintaining healthy trees. We collected data on thirty Douglas-fir trees and their associated dwarf mistletoe brooms before and after felling on four sites. Cross-sections cut from each infected branch and broom were used to determine the ages of the branches, the ages when they became infected and the age of each mistletoe broom. There were no strong relationships between broom size and broom age, or broom size and distance from the bole, height or platform size, the number of brooms in the trees, their Broom Volume Rating, diameter, age, crown class or surrounding density. This suggested that heavily infected or old infected trees may not necessarily yield the greatest number of large brooms for wildlife habitat. There were significant differences in the size, age and position of different types of brooms. Comparing the brooms in our sample with data from studies of spotted owl nests revealed differences among broom types that may be useful for management of infected stands in forests where maintaining broom habitat for wildlife is a consideration.

T. gondii is amenable to cellular, biochemical, molecular and genetic studies, making it a model for the biology of this important group of parasites. To facilitate forward genetic analysis, we have developed a high-resolution genetic linkage map for T. gondii. The genetic map was used to assemble the scaffolds from a 10X shotgun whole genome sequence, thus defining 14 chromosomes with markers spaced at &SIM; 300 kb intervals across the genome. Fourteen chromosomes were identified comprising a total genetic size of &SIM; 592 cM and an average map unit of &SIM; 104 kb/ cM. Analysis of the genetic parameters in T. gondii revealed a high frequency of closely adjacent, apparent double crossover events that may represent gene conversions. In addition, we detected large regions of genetichomogeneity among the archetypal clonal lineages, reflecting the relatively few genetic outbreeding events that have occurred since their recent origin. Despite these unusual features, linkage analysis proved to be effective in mapping the loci determining several drug resistances. The resulting genome map provides a framework for analysis of complex traits such as virulence and transmission, and for comparative population genetic studies.

The LIS virtual plant interface allows simplified and intuitive navigation of transcript data from Medicago truncatula, Lotus japonicus, Glycine max and Arabidopsis thaliana. Transcript libraries are represented as images of plant organs in different developmental stages, which are selected to query the analyzed and annotated data. Complex queries can be accomplished by adding modifiers, keywords and sequence names. The LIS also contains annotated genomic data featuring transcript alignments to validate gene predictions as well as motif and similarity analyses. The genomic browser supports comparative analysis via novel dynamic functional annotation comparisons. CMap developed as part of the GMOD project (http://www.gmod.org/cmap/index.shtml), has been incorporated to support comparative analyses of community linkage and physical map data. LIS is being expanded to incorporate gene expression and biochemical pathways which will be seamlessly integrated forming a knowledge discovery framework.

The cycle is active in the biology of both aerobic and anaerobic processes. Furthermore, the cycling of N in both natural and constructed wetlands is particularly dynamic and exceedingly valuable to N management for both productive agriculture and environmental quality. In this chapter, we illustrate N cycling in the context of three types of wetlands - constructed, riparian, and in-stream. We present the higher than expected rates of denitrification in constructed wetland used for animal wastewater treatment as an example of denitrification via new pathways such as ANAMMOX that require Less oxygen in the precursor oxidation of ammonia. We show the effectiveness of different riparian zones for stream buffering and de nitrification, particularly noting that they appear to provide a reasonable balance for protecting both water and air quality. We emphasize the importance of in-stream wetlands for assimilations and transformations of N that escapes agricultural watersheds. C1 USDA ARS, Florence, SC 29501 USA.

This study was designed to assess the independent effect of soy relative to animal protein and soy-derived isoflavones on circulating estrogen and androgen concentrations in postmenopausal women and older men. Forty-two subjects (> 50 yr) with low-density lipoprotein cholesterol levels of >= 3.36 mmol/l were fed each of 4 diets in randomized order for 6 wk/phase. All food and drink were provided. Diets contained 25 g soy or common sources of animal protein/4.2 MJ containing trace or 50 mg isoflavones/4.2 MJ. At the end of each diet phase, concentrations of estrone sulfate, estrone, estradiol, testosterone, androstendione, dihydrotestosterone, dehydroepiandrosterone, and dehydroepiandrosterone sulfate were measured. In postmenopausal women, concentrations of estrone were higher and its precursor, dehydroepiandrosterone, lower after consuming the soy compared with animal protein diets (P = 0.0396 and 0.0374, respectively). There was no significant effect of isoflavones on any of the hormones measured. In older men, dehydroepiandrosterone sulfate concentrations were lower after consuming the isoflavone (P = 0.0106) and higher after soy, compared with the animal protein diets (P = 0.0118). These data suggest that relatively large amounts of soy protein or soy-derived isoflavones had modest and limited sex-specific effects on circulating hormone levels.

Currently there is no effective cure for this disease. Risk factors include decreased lutein and zeaxanthin status and obesity. Obesity is also an increasing public health concern. The alarming increase in the prevalence of obesity further exacerbates the public health concern of AMD. The mechanism by which obesity increases the risk of AMD may be related to the physiologic changes that occur with this condition. These include increased oxidative stress, changes in the lipoprotein profile, and increased inflammation. These changes would also result in an increased destruction and a decreased circulatory delivery of lutein and zeaxanthin to the macula of the eye. Therefore, the mechanism by which obesity is related to AMD risk may be through indirect effects on changes in lutein and zeaxanthin status and metabolism.

Research Methods and Procedures: Dietary patterns, nutrient intake, cardiovascular disease (CVD), and MetS risk factors were characterized in 1615 Framingham Offspring-Spouse Study (FOS) women. Dietary pattern subgroups were compared for MetS prevalence and CVD risk factor status using logistic regression and analysis of covariance. Analyses were performed overall in women and stratified on obesity status; multivariate models controlled for age, apolipoprotein E (APOE) genotypes, and CVD risk factors. Results: Food and nutrient profiles and overall nutritional risk of five non-overlapping habitual dietary patterns of women were identified including Heart Healthier, Lighter Eating, Wine and Moderate Eating, Higher Fat, and Empty Calories. Rates of hypertension and low high-density lipoprotein levels were high in non-obese women, but individual MetS risk factor levels were substantially increased in obese women. Overall MetS risk varied by dietary pattern and obesity status, independently of APOE and CVD risk factors. Compared with obese or non-obese women and women overall with other dietary patterns, MetS was highest in those with the Empty Calorie pattern (contrast p value: p < 0.05). Discussion: This research shows the independent relationship between habitual dietary patterns and MetS risk in FOS women and the influence of obesity status. High overall MetS risk and the varying prevalence of individual MetS risk factors in female subgroups emphasize the importance of preventive nutrition interventions and suggest potential benefits of targeted behavior change in both obese and non-obese women by dietary pattern.

In this study, we present field data for leaf lifespan, specific leaf area (SLA) and mass and area-based leaf nitrogen concentrations (N-mass, N-area) of dominant tree species and the associated stand foliage N-pool, leaf area index (LAI), root biomass, aboveground biomass, net primary productivity (NPP) and soil available-N content in six undisturbed forest plots along subtropical to timberline gradients on the eastern slope of the Gongga Mountains. We developed a methodology to calculate the whole-canopy mean leaf traits to include all tree species (groups) in each of the six plots through a series of weighted averages scaled up from leaf-level measurements. These defined whole-canopy mean leaf traits were equivalent to the traits of a leaf in regard to their Interrelationships and altitudinal trends, but were more useful for large-scale pattern analysis of ecosystem structure and function. The whole-canopy mean leaf lifespan and leaf N-mass mainly showed significant relationships with stand foliage N-pool, NPP, LAI and root biomass. In general, as elevation increased, the whole-canopy mean leaf lifespan and leaf N-area and stand LAI and foliage N-pool increased to their maximum, whereas the whole-canopy mean SLA and leaf N-mass and stand NPP and root biomass decreased from their maximum. The whole-canopy mean leaf lifespan and stand foliage N-pool both converged towards threshold-like logistic relationships with annual mean temperature and soil available-N variables. Our results are further supported by additional literature data in the Americas and eastern China. C1 Chinese Acad Sci, Inst Tibetan Plateau Res, Beijing 100085, Haidian Dist, Peoples R China.

While CO2 stimulates net primary production, O-3 reduces photosynthesis, altering plant C allocation and reducing ecosystem C storage. The effects of multiple air pollutants can alter below-ground C allocation, leading to changes in the partial pressure of CO2 (pCO(2)) in the soil, chemistry of dissolved inorganic carbonate (DIC) and the rate of mineral weathering. As this system represents a linkage between the long- and short-term C cycles and sequestration of atmospheric CO2 changes in atmospheric chemistry that affect net primary production may alter the fate of C in these ecosystems. To date, little is known about the combined effects of elevated CO2 and O-3 on the inorganic C cycle in forest systems. Free air CO2 and O-3 enrichment (FACE) technology was used at the Aspen FACE project in Rhinelander, Wisconsin to understand how elevated atmospheric CO2 and O-3 interact to alter pCO(2) and DIC concentrations in the soil. Ambient and elevated CO, levels were 360 +/- 16 and 542 +/- 81 mul 1(-1), respectively; ambient and elevated O-3 levels were 33 +/- 14 and 49 +/- 124 nl 1(-1), respectively. Measured concentrations of soil CO, and calculated concentrations of DIC increased over the growing season by 14 and 22%, respectively, under elevated atmospheric CO2 and were unaffected by elevated tropospheric O-3. The increased concentration of DIC altered inorganic carbonate chemistry by increasing system total alkalinity by 210%, likely due to enhanced chemical weathering. The study also demonstrated the close coupling between the seasonal delta(13)C Of Soil pCO(2) and DIC, as a mixing model showed that new atmospheric CO2 accounted for approximately 90% of the C leaving the system as DIC. This study illustrates the potential of using stable isotopic techniques and FACE technology to examine long- and short-term ecosystem C sequestration.

This study simulated spatial-temporal patterns of birth and death rates and migration across a species' range in different seasons. Our results demonstrated the importance of dispersal and migration in altering birth and death rates, balancing source and sink habitats, and governing expansion or contraction of species' ranges in changing environments. We also showed that the multiple equilibria of metapopulations across a species' range could be easily broken following climatic changes or physical disturbances either local or regional. Although we refer to our models as describing the population dynamics across whole species' range, they should also apply to small-scale habitats (metapopulations) in which species abundance follows a humped pattern or to any ecosystem or landscape where strong central-marginal (C-M) environmental gradients exist. Conservation of both central and marginal populations would therefore be equally important considerations in making management decisions. C1 Univ Nebraska, Sch Nat Resources, Lincoln, NE 68583 USA.

However, the challenge of developing national or international monitoring programs is difficult often because of the lack of qualified biologists or other resources in key regions. More fundamentally, locally-based organizations that may have personnel and resources that could be involved in monitoring programs often have their own goals and locally defined monitoring objectives. These objectives may vary among regions and countries, but must be supported when designing and funding monitoring programs. Here we present a monitoring strategy that allows locally-based organizations to generate results that will have relevance to their local management efforts, while enabling them to participate in wider, regional and international monitoring efforts that will help to determine population trends and habitat relationships of both migratory and permanent resident birds, at a scale far greater than any single monitoring effort. It also allows to address basic research questions of the ecology and natural history of migratory and resident bird species. Through a cooperative effort such as outlined here, and with the use of protocols that incorporate standardized monitoring methods, we can evaluate the efficacy of conservation and management actions throughout the Americas, while also fulfilling locally-defined conservation and monitoring objectives.

In this study, we describe the spatial and temporal distributions of the four major pine-infesting bark beetles at four sites along two elevational gradients on the Eldorado and Stanislaus National Forests. A total of 914,864 Dendroctonus brevicomis LeConte, 30,391 D. ponderosae Hopkins, 62,215 Ips paraconfusus Lanier, and 1828 I. pini (Say) were collected during the 3-year period. Total trap catch was negatively correlated with elevation for D. brevicomis and I. paraconfusus (P < 0.003), but not D. ponderosae and I. pini (P > 0.08). Approximately 84.3% of all D. brevicomis and 67.2% of all L paraconfusus collected at Eldorado and Stanislaus were captured at the lowest elevation site (823 and 1000 m, respectively). Dendroctonus ponderosae was collected most frequently at the third highest elevation site at each transect (1829 and 1707 m, respectively). The distribution of D. ponderosae was aggregated among mid-elevation sites (12801829 m) as 68.8% of all captures occurred here. Ips pini was captured most frequently at the highest elevations, but in general relatively few individuals were collected during the course of this study. Dendroctonus brevicomis was active throughout the entire sampling interval at the lowest elevations, but at mid- and high elevations captures peaked in late spring followed by decreasing numbers of individuals collected throughout the year. At the lowest elevations, D. ponderosae exhibited a single peak in June at Stanislaus (Site E), and a bimodal distribution with peaks occurring in April and November at Eldorado (Site A). In general, D. ponderosae was active throughout the entire sampling interval at mid- and high elevations. The temporal distribution of L paraconfusus was consistent among all elevations with peak activity occurring prior to July. Few consistent trends in flight periodicity were observed for L pini. In general, elevation strongly affected the spatial and temporal distributions of these species. C1 USDA, Forest Serv, Pacific SW Res Stn, Davis, CA 95616 USA.

The community of egg parasitoids was the same in plots regardless of treatment dose (0, 12.5 g or 25 g per hectare) and consisted of three species of parasitic wasps (Telenomis californicus Ashmead (Hymenoptera: Scelionidae), Trichogramma minutum Riley (Hymenoptera: Trichogramnatidae) and Tetrastichus sp. (Hymneoptera: Eulophidae)). There was a significant, negative con-elation ([P > r] = 0.0483) between egg mass density and dose of the pheromone that was applied to the plots. However. there was not a significant correlation between the treatment dose and the ratio of parasitoids per larva reared from egg masses collected during either the autumn ([P > r] = 0.7605) or spring ([P > r] = 0.6718) following the treatment application. Significantly more parasitoids per larva emerged from egg masses collected in the treated plots compared with untreated plots for egg masses collected during the autumn sample period ([P > t] = 0.0086). There were no differences in the number of parasitoids per larva emerging from egg masses collected the spring following treatment application ([P > t] = 0.6283). The increase in egg parasitism during the autumn following pheromone application could benefit the overall control effect of the mating disruption treatment.

Samples of mineral soil, bulk Litter material, macroarthropods and understory plants were collected from ten experimental. forest stands. Half of the stands were previously thinned 17-42 years ago, the other half served as controls. Values of delta(15)N and delta(13)C were based on the analysis of almost 500 individuals of at Least 22 species in 11 arthropod families. The isotopic analysis showed a significant increase in delta(15)N and delta(13)C values with soil depth. Isotopic signatures of macroarthropods ranged from -26.51 parts per thousand to -20.52 parts per thousand for delta(13)C and -2.85 parts per thousand to 5.10 parts per thousand for parts per thousand(15)N. All consumers showed levels of delta(13)C enrichment substantially higher than those of primary producers and Litter. Predators were generally significantly more N-15 enriched than detritivores and herbivores, but their delta(13)C levels were similar to those of primary consumers. Our data indicate that this community consists of at least 2-3 trophic levels with a considerable amount of variation in the N-15 enrichment among detritivores and predators. We suggest that the spread of delta(15)N values of predators likely reflects the diversity of potential. prey among detritivores and a varying degree of intraguild predation among different species. Our findings generally agree closely with the results of similar studies from other forest litter communities. Thinning did not appear to influence the overall, isotopic composition of the detrital. food web. Extensive omnivory and intraguild predation among Litter consumers may buffer long-term effects of thinning on the trophic structure of these species-rich communities. (c) 2004 Elsevier GmbH.

We used pairwise combinations of gamma-irradiated litter of five tree species with cultures of two dominant microfungi derived from each plant in a microcosm experiment. The experiment was designed to test whether early leaf decomposition rates differed depending on relationships between the leaf litter from which the fungi were derived (i.e., the source plant) and the leaf substrata decomposed by these fungi in microcosms. Relationships tested were phylogenetic relatedness between the source and substratum leaves, and similarity in litter quality (lignin, N and P) between the source and substratum. We found a significant interaction between microfungi and leaf species (P < 0.0001), and differences among the four classes of source-substratum relationships were highly significant (P = 0.0004). Combinations in which fungal source leaves were of the same species or family as the substratum, or the fungal source resembled the substratum in quality had marginally faster decomposition than when the fungal source and substratum leaves were mismatched (i.e., unrelated and of dissimilar quality). In some microcosms, a basidiomycete contaminant had a strong additive effect on decomposition of Croton poecilanthus leaves resulting in faster decomposition than with microfungi alone (P < 0.0001). Comparisons among leaf-microfungal combinations were made after the effect of the basidiomycete covariate was adjusted to zero. The data on microfungi suggest differential abundance in particular hosts, which contributes to species diversity of decomposer fungi in tropical forests, affects rates of decomposition.

Insect tachykinin-related peptides, also referred to as "insectatachykinins", produce dose-dependent calcium and cyclic AMP responses in cultured Drosophila melanogaster Schneider 2 (S2) cells that were stably transfected with the cloned STKR cDNA. Pronounced differences in Pharmacology were observed between agonist-induced calcium and cyclic AMP responses. The results indicate that the pharmacological properties of STKR depend on its coupling to a unique second messenger system. Therefore, a model postulating the existence of multiple active receptor conformations is proposed. This article presents the first evidence that an insect peptide receptor with dual coupling properties to second messenger systems can display agonist-dependent functional differences.

In the analog, the acidic Sulfate group is replaced with an acidic carboxyl group. The degree of activity of sulfakinin analogs is correlated with the carboxyl/alpha-carbon distance in the cockroach hindgut contractile assay. The results represent an important step in the design and synthesis of biostable, sulfakinin analogs that could potentially Suppress the feeding behavior of destructive insect pests of agricultural importance.

Landscape structure, such as the variation found along the complex gradients of the Northwest mountain ecoregions, affects the expansion of invasive plant species and the invasibility of plant communities. Also, the history of land use and current use patterns affect the expansion of invasive plants, and many of the deteriorated environments in the region's mountains may invite and stabilize plant invasions. We examined the patterns of invasive plant diversity in Northwest mountain ecoregions, is derived from literature sources, to analyze which factors influence plant invasions. Our analysis found altered riparian systems and disturbed forests to be especially vulnerable to plant invasion. Conversely, alpine and wilderness areas are still relatively unaffected by invasive plants. Both riparian and alpine communities, while making up a relatively small area across Northwest mountain ecoregions, have significant ecological importance and deserve special protection from invasive plant introductions. Human settlement at low elevations and intense land use of upland forests will likely continue to enhance invasive plant introductions into Northwest mountain ecosystems. Knowledge of the relationships between biological and environmental factors, disturbance, and human land use will be critical for future management strategies that proactively locate, prevent, or contain plant invasions in the mountains of the Northwest.

Xylem fluid samples were collected at regular intervals and from multiple locations within field-grown citrus trees to determine imidacloprid and thiamethoxam concentrations using commercial ELISA kits. Uptake profiles varied considerably with peak mean titers of imidacloprid occurring 6-8 weeks after application compared with 2 weeks for thiamethoxam. The persistence of each compound also varied as near-peak levels of imidacloprid were sustained for another 6-10 weeks before gradually declining. In contrast, thiamethoxam titers declined more rapidly after the initial peak, possibly reflecting an application rate only one-quarter of that used for imidacloprid. Within-tree distributions were more similar for the two compounds, with no significant effect due to height of the sample (upper or lower half) or to the quadrant location within the tree, with the exception of one quadrant in the thiamethoxam-treated trees. Substantial reductions in GWSS nymphs and adults were observed in imidacloprid-treated trees during the 2001 trial and were sustained for 4-5 months after treatment. Treatment effects on nymphs were not as well pronounced in the 2002 trial, when overall GWSS infestations were much reduced from the previous year. However, consistently lower adult infestations were still observed in 2002 for both treatments compared with untreated trees. Information on the spatial and temporal profiles in citrus trees was obtained for both compounds to complement field impact data and improve understanding of their pest management potential.

Suc accumulation has often been linked with increased activity of sucrose phosphate synthase (SPS; EC: 2.4.1.1.14). SPS, a key enzyme in sucrose biosynthesis, is controlled by an intricate hierarchy of regulatory mechanisms including allosteric modulators, reversible covalent modification in response to illumination, and transcriptional regulation. We hypothesized that during long day conditions in the Antarctic summer D. antarctica can maintain high SPS activity longer by indirect light regulation, thereby leading to a high sucrose accumulation in the leaves. The objectives of this study were to investigate a possible indirect light regulation of SPS activity and the effect of cold and day length on transcriptional and protein level of SPS in D. antarctica. Although SPS activity did not display an endogenous rhythm of activity in continuous light, activation of SPS at the end of the dark period was observed in D. antarctica. This activation of SPS is possibly controlled by covalent modification, because it was inhibited by okadaic acid while the SPS protein level did not significantly change. The highest SPS activity increase was observed after 21 days of cold-acclimation under long day conditions. This increased activity was not related to an increase in SPS gene expression or protein content. High SPS activity in cold long days leading to hyper accumulation of Suc appears to be among the features that permit D. antarctica to survive in the harsh Antarctic conditions.

I tested whether these two methods of EC treatments produced differences in the seed yield of soybeans. Tests were conducted for four growing seasons, using open top chambers, with soybeans rooted in the ground in field plots. One third of the chambers were flushed with air at the current ambient [CO2] (AC), one third had [CO2] 350 mu mol mol(-1) above ambient during the daytime (ECd) while one third had [CO2] 350 mu mol mol(-1) above ambient for 24 h per day (ECd,). ECdn increased seed yield by an average of 62 % over the four years compared with the AC treatment, while ECd increased seed yield by 34 %. Higher seed yield for ECdn compared with ECd occurred each year. In comparing years, the relative yield disadvantage of ECd decreased with increasing overall seed yield. On days with high water vapor pressure deficits, soybean canopies with ECd had smaller midday extinction coefficients for photosynthetically active radiation than canopies with ECdn, because of a more vertical leaf orientation. Hence the seed yield of soybean at EC varied depending on whether EC was also provided at night, with much greater yield stimulation for ECdn than for ECdn in some years.

This relation Would be reflected in the ratio of C-i to external ambient (C-a) carbon dioxide concentration, which is often given as 0.3 or 0.4 for C-4 plants. For a C-a of 360 rho mol mol(-1) that Would mean a C-i about 110-140 mu mol mol(-1). Our field observations made near midday on three weedy C-4 Species, Amaranthus retroflexus, Echinochloa crus-galli, and Setaria faberi, and the C-4 crop Sorghum bicolor indicated mean values of C-i of 183-212 mu mol mol(-1) at C-a = 360 mu mol mol(-1). Measurements in two other C-4 crop species grown with three levels of N fertilizer indicated that while midday values of Ci at high photon flux were higher at limiting N, even at high nitrogen C-i averaged 212 and 196 mu mol mol(-1) for Amaranthus hypochondriacus and Zea mays, respectively. In these two crops midday C-i decreased with increasing leaf to air water vapor pressure difference. Averaged over all measurement days, the mean C-i across all C-4 species was 198 mu mol mol(-1), for a C-i/C-a ratio of 0.55. Prior measurements oil four herbaceous C-3 species using the same instrument indicated all average C-i/C-a ratio of 0.69. Hence midday C-i values in C-4 species under field conditions may often be considerably higher and more similar to those of C-3 species than expected from measurements made oil plants in controlled environments. Reducing gs in C-4 crops at low water vapor pressure differences Could potentially improve their water use efficiency without decreasing P-N.

HPLC-MS along with ID, 2D and 3D NMR spectra provided the requisite structural evidence that it is the di-5-O-L-arabinosyl ester of 8-O-4-DFA. Although a range of DFAs have been well authenticated as components released from the cell walls of grasses, the only structural evidence for a DFA attached to polysaccharides had been from 5-5-DFA. The isolation of the 8-O-4-ester demonstrates that polysaccharides in maize cell walls, and presumably in all grasses, are cross-linked through dehydrodiferulates other than 5-5-dehydrodiferulate.

A steady-state, open photosynthetic system was designed and used in the field to supply a small leaf cuvette with conditioned air stream (growth CO2 concentrations, humidified, cooled) and augmented with either background or elevated O-3. Two innovations led to success: 1) supplying the cuvette with cooled air instead of Peltier cooling within the cuvette; and 2) using a custom-designed, low flow (capable of 100 seem), fast response (20 S) O-3 monitor. We tested whether elevated CO2 would alter stomatal response to short term, steady state elevated O-3. Holm oak (Quercus ilex L., Fagaceae), an evergreen broadleaf tree growing near a geothermal CO2 vent, has been exposed over its lifetime to a gradient of CO2 concentrations. We chose trees in areas averaging 450 mu l 1(-1) (low background CO2) and 1500 mu l 1(-1) (super-elevated CO2). Background O-3 exposure at this site is moderate (10 am to 5 pm averages of 62 nl 1(-1) in June). We measured gas exchange at the growth CO2 levels, and at ambient O-3 or 1.7x ambient O-3 concentrations. At low background CO2, short term elevated O-3 depressed foliar transpiration. Because there was little concurrent change in net assimilation, instantaneous transpiration efficiency was increased. At super-elevated CO2, short term elevated O-3 did not affect foliar transpiration. Because there was a concurrent decrease in net assimilation, instantaneous transpiration efficiency was decreased at elevated CO2 and O-3. C1 USDA, Pacific SW Res Stn, Riverside, CA 92507 USA.

High ozone concentrations have been shown to be harmful to plants not only within urban areas but also in remote regions such as national forests and parks in the USA. While meteorological stations collecting hourly data are available in many remote areas, there are only a handful of locations with continuous ozone monitors in the Sierra Nevada. This necessitates the need for a statistical model that predicts ozone concentrations from meteorological data. In this paper we develop an autoregressive model that uses nonparametric smoothing splines to estimate the nonlinear effects of meteorological data and fire history on diurnal ozone levels. The estimated relationships may be useful, among other things, as input to dynamic ozone forecasting models (e.g. MM5) to estimate ozone levels at locations or times with no active monitor data or to study effects of nearby prescribed and wild fires on ambient ozone levels.

Isolates front all three regions were tested on 25 oat lines with single P. coronata (Pe) genes for crown rust resistance from A. sterilis and one line with a Pc gene from A. sativa. Isolates from Israel were tested also on 11 Iowa backcross lines with undesignated crown rust resistance genes from A. sterilis. Four associated virulence groups were identified from significant positive virulence associations that were consistent across all three regions. Group 38 included virulence to Pc-38, Pc-39, Pc-55, Pc-63, and Pc-71; group 45 included virulence to Pc-45, Pc-46, Pc-48, Pc-52, Pc-54, and Pc-57; group 58 included virulence to Pc-35, Pc-40, Pc-58, and Pc-59; and group 61 included virulence to Pc-36, Pe-51, Pe-56, Pc-60, and Pc-61. Virulence to Pc-70 showed the strongest association to virulences in group 38 but also showed significant association with virulence to Pc-45, Pc-35, and Pc-58. Virulences in group 61 were consistently negatively associated with virulences in group 38 in each region. In Israel, virulences to five of the Iowa lines showed positive associations to virulences in group 61 and negative associations to virulences in groups 38 and 45.

Hundreds of thousands of tanoaks, coast live oaks and California black oaks have died from pathogen infection since the disease was first detected in 1995. Prevention and management of the disease are difficult because of complexities associated with the pathogen. Existence of numerous diverse hosts, manifestation of three different diseases by the pathogen in different infected hosts, occurrence of other canker-causing Phytophthora species on the same Fagaceae species, and regular movement of massive numbers of nursery hosts are important complicating factors. No effective treatment exists for controlling SOD across the landscape; sanitation and suppression measures are used to stop disease spread in regulated areas. Regulatory controls have not stopped pathogen movement to other states outside the affected zones via infected nursery plants; however, no known case of SOD exists outside of California and Oregon in the U.S. A strategic plan has been developed by the U.S. Department of Agriculture to coordinate prevention, detection, management, and restoration efforts funded by the U.S. Congress.

The goals of this study were to investigate the relationships between physiological parameters and growth performance and quantify the respective genotypic differences using multivariate analysis.. Plants of thirty-one genotypes were grown in sand tanks in a greenhouse and irrigated with Yoshida nutrient solution. Two salinity treatments were imposed at 0.9dS m(-1) ( control) and 6.4 dS m(-1) with sodium chloride and calcium chloride (&SIM; 6: 1 molar ratio). Seedlings were sampled 34 days after planting (7th to 8th leaf stage). The characters of Na+, K+, Ca2+, K-Na selectivity (SK, Na) and Na-Ca selectivity (S-Na, (Ca)) were measured as physiological parameters. The characters of tiller number, leaf area, plant height and shoot dry weight were measured as growth performance. Under salinity stress, SK, Na increased whereas SNa, Ca decreased compared to the controls. Canonical correlation analysis indicates a strong relationship between physiological parameters and growth performance. Tiller number is a desirable parameter among the growth parameters analyzed to predict seedling growth under salinity stress. Genotypes grouped into four clusters based on ion contents and ion selectivity using Ward's minimum-variance cluster analysis. SK, Na and shoot Na+ content contributed the most to the cluster formation. Similarly, genotypes grouped into four clusters based on growth performance. Genotypes were classified into three categories based on ion cluster rankings: Category 1 with high SK, Na and low shoot Na+ content; Category 2 with intermediate SK, Na and shoot Na+ content; Category 3 with low SK, Na and high shoot Na+ content. The classification of the genotypes into Categories 1 and 3 based on their high or low SK, Na was generally consistent with their growth performance under salt stress. In contrast, ion selectivity was a less dominant mechanism controlling salt tolerance in Category 2 with intermediate SK, Na. It was concluded that ion selectivity was a relatively dominant mechanism controlling salt tolerance among rice genotypes although multiple mechanisms may be involved under moderate salt stress. The results also provide the first example of the effectiveness of cluster analysis for physiological responses to salinity stress. C1 USDA ARS, George E Brown Jr Salin Lab, Riverside, CA 92507 USA.

Increases in root production of over 60% were observed with elevated CO2 during years of intermediate levels of precipitation, with smaller effects in a very wet year and no effects in a very dry year. Aboveground to belowground production ratios, and the depth distribution of root production, did not differ between ambient and elevated CO2 treatments. Root soluble concentrations increased an average of 11% and lignin concentrations decreased an average of 6% with elevated CO2, while nitrogen concentrations decreased an average of 21%. However, most tissue quality responses to CO2 varied greatly among years, andC:N ratios were higher in only one year (22 ambient vs. 33 elevated). Among years, root nitrogen concentrations declined with increasing aboveground plant nitrogen yield, and increased over the study period. Estimates of root production by the ingrowth donut method were much lower than previous estimates in the shortgrass steppe based on C-14 decay. We discuss reasons why all ingrowth methods will always result in relative rather than absolute estimates of root production.

To determine the incidence of SbDV in Illinois, we collected clovers and forage legumes in a total of 49 Illinois counties in 2001 and 2002 and tested them for the presence of SbDV by reverse-transcription-polymerase chain reaction. SbDV was detected in 43% of red clover (Trifolium pratense), 10% of white clover (T. repens), and 3% of yellow sweet clover (Melilotus officinalis) plant samples. The dwarfing strain (SbDV-D) was the predominant strain detected in Illinois. In 2000, Aphis glycines, an aphid species that colonizes soybeans, was reported for the first time in North America. To determine whether A. glycines or aphid species found colonizing clover were vectors of SbDV, transmission studies were conducted. Aphids of the species Nearctaphis bakeri reproducibly vectored SbDV among red clovers, and from red clover to soybean. A. glycines did not transmit SbDV; neither did two other clover-infesting aphid species, Acyrthosiphon pisum and Therioaphis trifolii. C1 Univ Illinois, USDA ARS, Dept Crop Sci, Urbana, IL 61801 USA.

Losses caused by the disease are usually seen as a postharvest rot with orange spore masses appearing on the surface of affected fruit. One hundred cultivars/selections of blueberry were screened for resistance to fruit rot between 1993 and 2003 by inoculating container-grown plants bearing green fruit. Visible rot symptoms on ripe fruits were evaluated after a 1-week incubation at room temperature. Our analyses revealed that infection levels were affected by mean May temperatures in New Jersey, generally increasing as temperatures increased; however, this effect was not consistent among all cultivars. A generalized linear mixed model was developed to predict resistance at the historic mean May temperature, conservatively explaining 59% of the variance in resistance. Percent infection ranged from 9 to 91% with a mean of 51% across all cultivars. Results for common cultivars corresponded well with field reports of their relative susceptibilities. An estimate of narrow-sense heritability of 0.32 suggested additive inheritance of resistance. Since very high inoculum loads were used in this study, cultivars exhibiting a low percentage of fruit rot are predicted to show superior field resistance to the disease and will be incorporated into an ongoing breeding program.

The experiment was repeated in 2001. Sphacelia associated with infected sorghum panicles were placed in nylon mesh bags and either buried at a 10-cm depth, placed on the soil surface, or suspended 61 cm above the ground. Samples were recovered after 4, 8, and 12 months and assessed for pathogenicity of surviving macroconidia by macerating tissue in water and spraying it onto panicles of flowering male-sterile sorghum in the greenhouse. Survival of ergot macroconidia in recovered particles declined at all locations after the first 4 months that particles were left in the field. The decline in viability during this period was greater in 2001 than in 2000. In 2000, survival after 4 months was greatest at Lubbock and Bushland, which have a continental steppe climate, than at the other three Texas locations, Weslaco and Corpus Christi, which have a subtropical subhumid climate, and College Station, which has a subtropical humid climate. However, this difference in survival was not as pronounced in 2001. Additionally, after 8 months, survival levels at all locations were similar. At the end of 12 months, infective macroconidia were found only at Lubbock in 2000, and only at Lubbock and College Station in 2001. Ergot macroconidia can survive in all major sorghum production areas of Texas; thus, conidia would not need to move long distances in order to initiate an epiphytotic.

All accessions were evaluated for leaf rust (Puccinia triticina) resistance in field plots at Tel Aviv, and subsets of 284 and 468 accessions were tested in the greenhouse in Tel Aviv and St. Paul, MN, respectively, for seedling resistance to leaf rust; 460 accessions were also tested for seedling resistance to stem rust (Puccinia graminis f. sp. tritici) in St. Paul. One accession was highly resistant to leaf rust in seedling tests in Tel Aviv, and 21 others had moderately susceptible to moderately resistant seedling resistance. Four accessions were highly resistant to leaf rust in seedling tests in St. Paul, and 11were resistant to at least one stem rust race. Adult resistance to leaf rust was more common than seedling resistance among the accessions; 21 accessions had less than 25% leaf rust severity in field plots compared with 80 to 90% severity for highly susceptible accessions. Most of the accessions with effective adult plant resistance came from two nearby locations in Upper Galilee, a region where populations of T dicoccoides are most extensive and genetically diverse. These accessions may provide valuable new partial resistance genes for durable protection against leaf rust in cultivated wheat. C1 Univ Minnesota, Dept Plant Pathol, St Paul, MN 55108 USA.

The wind/rain-splash events were simulated using electric blowers to generate turbulent wind (15 to 20 m s(-1)) and sprayer nozzles to produce water droplets entrained in the wind flow. The splash was blown at an inoculum source of canker-infected trees I m downwind. The splash downwind of the source of the infected trees was collected by vertical panel samplers and funnel samplers. The duration over which bacteria were dispersed in spray was assessed in continuous wind at intervals from 0 to 52 It after commencing the simulated rain splash event. In one experiment on 11 February 2003, a total of 1.48 x 10(6) bacteria were collected by panels 1 m downwind from the inoculum source during the first 10 min of dispersal, but the numbers declined to 3.60 x 10(5) bacteria after 1 h and ranged between 1.42 x 10(5) and 1.93 x 10(4) up to 52 h. In a more detailed study (15 July 2003) of dispersal duration over 4 It, the greatest quantity of bacteria collected by panel samplers were dispersed in the first 5-min period (1.01 x 10(8) bacteria collected). By 10 min after initiation of dispersal, approximately one-third (3.09 x 10(7) bacteria collected) of the initial number was being dispersed, and by the end of the first hour, only one-tenth (1.31 x 10(7) bacteria collected) of the initial quantity was dispersed. Funnel samplers placed at ground level under the trees showed a similar trend. The distance to which bacteria were dispersed in wind-blown splash was also tested under simulated conditions: on 18 September 2003, bacteria were collected by panel samplers at all distances sampled (1, 2, 4, 6, 8, 10, and 12 m) with the greatest number of bacteria deposited at 1 m (4.93 x 10(6) bacteria collected), while 2.22 x 10(3) bacteria were deposited over a 10-min period 12 m from the inoculum source. Wind speed declined from 19.5 m s(-1) upwind of the trees to 2.8 in s(-1) 1 m downwind, and by 4 m downwind from the inoculum source, movement was similar to the surrounding air. The data on duration and distance of dispersal were best described by power law regression models compared to exponential models. Citrus canker is readily dispersed in wind-driven rain and is dispersed in large quantities immediately after the stimulus occurs, upon which wind-driven splash can disperse inoculum over a prolonged period and over a substantial distance.

In spite of this long time scale, selection on life history attributes that affect seedling recruitment should be strong. We studied factors affecting germination phenology and seedling establishment for Coleogyne ramosissima, a dominant shrub species in the ecotone between warm and cold deserts in western North America. We also examined ecotypic differentiation in establishment strategy in response to selection regimes in two contrasting habitats. We followed patterns of dormancy loss, germination, emergence, and survival in reciprocal field experiments at warm winter Mojave Desert and cold winter Colorado Plateau study sites. Seed germination took place in late winter, under winter rain conditions at the warm desert site and under snow at the cold desert site. Distinctive germination phenologies for the two seed populations at contrasting field sites followed predictions based on laboratory germination experiments. There was no seed bank carryover across years. Seedling survival at the end of three growing seasons was remarkably high (mean survival 54%). Most seedling mortality was due to sprout predation by rodents early the first spring in unprotected caches. Emergence and establishment at each site were significantly higher for seeds from the local population, supporting the idea of ecotypic differentiation in establishment strategy. Establishment success was an order of magnitude greater overall at the Colorado Plateau site, which represents the leading edge of an upward elevational shift in distribution for this species under the current climatic regime. The Mojave Desert site is on the trailing edge of this shift, and recruitment there is apparently a much less frequent occurrence.

We present a first-year account of suppression of oak seedlings in relation to Rhododendron and Kalmia basal area, light and resource availability, seedling performance and the rates of seedling damage (i.e., herbivory). We found no evidence of first-year seedling suppression or significant resource deficiencies beneath thickets of K. latifolia in mature mixed hardwood stands. Suppression beneath R. maximum was apparent during the first growing season. We found that seedling biomass, light availability prior to canopy closure, and seedling tissue C:N ratios were negatively correlated with R. maximum basal area. Basal area of R. maximum was positively correlated with seedling mortality rates, soil [Al], and early-growing season leaf herbivory rates. Seedling growth was positively correlated with light and tissue C:N, while negatively correlated with soil [Al]. Overall, our results support the inhibition model of shade-mediated carbon limitation beneath dense understory shrubs and indicate the potential importance of herbivory and aluminum toxicity as components of a suppression mechanism beneath R. maximum thickets. We present a causal model of first year inhibition beneath R. maximum in the context of our findings and the results of prior studies.

Cloning of the genes encoding GA biosynthetic and inactivating enzymes has led to numerous insights into the developmental regulation of GA hormone accumulation that is subject to both positive and negative feedback regulation. Genetic and biochemical analysis of GA-signaling genes has revealed that posttranslational regulation of DELLA protein accumulation is a key control point in GA response. The highly conserved DELLA proteins are a family of negative regulators of GA signaling that appear subject to GA-stimulated degradation through the ubiquitin-26S proteasome pathway. This review discusses the regulation of GA hormone accumulation and signaling in the context of its role in plant growth and development. (c) 2005 Elsevier Inc.

In this report we provide further insight into genetic elements affecting transcription of P-deficiency-induced genes. Moreover, we also show that sugars and photosynthates are integrally related to P-deficiency-induced gene expression. White lupin phosphate transporter (LaPT1) and secreted acid phosphatase (LaSAP1) promoter-reporter genes when transformed into alfalfa, a heterologous legume, showed significant induction in roots specifically in response to P-deficiency. In addition, both promoters were active in nitrogen-fixing root nodules but not in ineffective nodules indicating a link between P-deficiency and factors related to nitrogen fixation/metabolism. As sugars play a role in signal transduction during nitrogen assimilation and are required for effective nitrogen fixation, we tested the relationship of sugars to P-deficiency-induced gene expression. Exogenous sucrose, glucose, and fructose stimulated LaPT1 and LaSAP1 transcript accumulation in dark-grown P-sufficient white lupin seedlings. Furthermore, in intact P-deficient white lupin plants, LaPT1 and LaSAP1 expression in cluster roots was strikingly reduced in dark-adapted plants with expression rapidly restored upon reexposure to light. Likewise, interruption of phloem supply to P-deficient roots resulted in a rapid decline in LaPT1 and LaSAP1 transcript accumulation. Similar results were also obtained with a third lupin P-deficiency-induced gene encoding a putative multidrug and toxin efflux protein (LaMATE). Taken together, our data show that the regulation of P-deficiency-induced genes is conserved across plant species and sugars/photosynthates are crucial for P-deficiency signal transduction.

This encoded a polypeptide of 124 amino acids showing 87 identity with WBP1A, a wheat lipid transfer protein (LTP), but much lower homology to other barley LTPs. In addition to the epicarp, this Ltp-like gene, Ltp6, is highly expressed in coleoptiles and embryos under normal growth conditions. Messenger RNA levels increased in seedling tissues during salt and cold treatments and under applied abscisic acid (ABA) and salicylic acid (SA). Taken together, Ltp6 tissue-specific and response patterns are distinct from other known barley Ltp genes. Inverse PCR was used to derive 2345 bp of upstreamLtp6 sequence. The level of transcription conferred by different promoter deletion constructs was assessed by quantitative real time RT-PCR using gfpas a reporter in transient expression assays. All constructs containing at least 192 bp of upstream sequence and the 5'UTR conferred tissue-specific expression and retained most of the promoter strength. Deletion of 64 bp (-192/-128) from this upstream sequence reduced expression levels by 80. Moreover, a minimal 247 bp Ltp6promoter continuously drove gfp expression during spike development, from early ovary differentiation through its final expression in the epicarp and during embryogenesis and germination in transgenic barley, reproducing the expression pattern of the native gene. The potential use of this promoter sequence for targeting transgene-mediated disease resistance in barley and wheat is discussed. C1 ARS, USDA, Cereal Crops Res Unit, Madison, WI 53726 USA.

Nonetheless, the correlation between Al resistance and this Al-exclusion mechanism has not been tested beyond a very small number of Al-resistant and Al-sensitive maize lines. In this study, we conducted a comparative study of the physiology of Al resistance using six different maize genotypes that capture the range of maize Al resistance and differ significantly in their genetic background (three Brazilian and three North American genotypes). In these maize lines, we were able to establish a clear correlation between root tip Al exclusion (based on root Al content) and Al resistance. Both Al-resistant genotypes and three of the four Al-sensitive lines exhibited a significant Al-activated citrate exudation, with no evidence for Al activation of root malate or phosphate release. There was a lack of correlation between differential Al resistance and root citrate exudation for the six maize genotypes; in fact, one of the Al-sensitive lines, Mo17, had the largest Al-activated citrate exudation of all of the maize lines. Our results indicate that although root organic acid release may play a role in maize Al resistance, it. is clearly not the only or the main resistance mechanism operating in these maize roots. A number of other potential Al-resistance mechanisms were investigated, including release of other Al-chelating ligands, Al-induced alkalinization of rhizosphere pH, changes in internal levels of Al-chelating compounds in the root, and Al translocation to the shoot. However, we were unsuccessful in identifying additional Al-resistance mechanisms in maize. It is likely that a purely physiological approach may not be sufficient to identify these novel Al-resistance mechanisms in maize and this will require an interdisciplinary approach integrating genetic, molecular, and physiological investigations.

As a result, the chilling-sensitive plants dry out and may die. Using a chilling-sensitive and a chilling-tolerant maize genotype we investigated the effect of chilling on L-o, and its relationship to osmotic water permeability of isolated root cortex protoplasts, aquaporin gene expression, aquaporin abundance, and aquaporin phosphorylation, hydrogen peroxide (H2O2) accumulation in the roots and electrolyte leakage from the roots. Because chilling can cause H2O2 accumulation we also determined the effects of a short H2O2 treatment of the roots and examined the same parameters. We conclude from these studies that the recovery of Lo during chilling in the chilling-tolerant genotype is made possible by avoiding or repairing membrane damage and by a greater abundance and/or activity of aquaporins. The same changes in aquaporins take place in the chilling-sensitive genotype, but we postulate that membrane damage prevents the Lo recovery. It appears that the aquaporin response is necessary but not sufficient to respond to chilling injury The plant must also be able to avoid the oxidative damage that accompanies chilling.

Therefore, we initiated a long-term CO2-enrichment experiment on sour orange trees in 1987. Four sour orange trees (Citrus aurantium L.) have been grown from seedling stage at 300 mu mol mol(-1) CO2 above ambient in open-top, clear-plastic-wall chambers at Phoenix, Arizona. Four control trees have been similarly grown at ambient CO2. All trees have been given ample water and nutrients. The ratios of wood plus fruit annual biomass increments of the elevated-CO2 trees to those of the control trees reached a peak of about 3.0 two years into the experiment, declined from about year 2 to year 8, and has plateaued at about 1.75 for the past 9 years. The enhancement ratio for net photosynthesis was about 2.8 in year 2 but had declined to 1.3 by the 14th year, indicating some acclimation to the elevated CO2. Initial reductions in leaf N concentrations disappeared by year 7, while carbohydrate concentrations remained higher. Intrinsic water use efficiency determined from carbon isotope ratios was increased under elevated-CO2 by the same amount as biomass, which implies water use was unchanged. Storage proteins have been detected in the leaves of the enriched trees, which might be a mechanism that enables a six-fold increase in the rate of bud burst in the spring.

DES119) and characterized. Genomic origin analysis reveals that GhMyb7 and 9 are alloallelic genes in the allotetraploid cotton (AD genome). GhMyb7 is derived from the A(2) subgenome, whereas GhMyb9 is from the D-5 subgenome. Northern blot analysis showed that GhMyb7/9 is expressed in flowers and fibers, and its expression in fibers is developmentally regulated. Auxin treatment increases transcript levels of GhMyb7/19 in fiber cells in an in vitro ovule culture system. The Escherichia coli-expressed GhMYB7 fusion protein binds to the promoter region (nt -614 to -580) of Ltp3, a cotton-fiber-specific gene, in an in vitro DNA-protein-binding assay, Suggesting that GhMYB7/9 may play a role in the transcriptional regulation of the Ltp3 gene during fiber development. The overexpression of GhMyb7 in both transgenic tobacco and Arabidopsis plants causes a pleiotropic effect on plant development, including dwarf, abnormal leaf shape. and retarded root development. The late-flowering phenotype is observed in the 35S:GhMyb7 transgenic tobacco and Arabidopsis plants under long day (LD) condition. The transgenic Arabidopsis plants, however, show the absence of inflorescence under short day (SD) condition, suggesting that GhMYB7 overexpession might inhibit the GA biosynthesis or signaling pathway.

Two predominant glycoalkaloids, alpha-chaconine and alpha-solanine are produced in potatoes. An antisense transgene was constructed to down-regulate glycoalkaloid biosynthesis using a potato cDNA encoding a sterol alkaloid glycosyltransferase (Sgt1). Introduction of this construct into potatoes resulted in some lines with an almost complete inhibition of alpha-solanine accumulation. This inhibition was compensated by elevated levels of alpha-chaconine and resulted in wild type total SGA levels in the transgenic lines. In vitro assays with the recombinant SGT1 isolated from yeast demonstrated that Sgt1 encodes an enzyme capable of both glucosyltransferase and galactosyltransferase activity with a preference for UDP-galactose as the sugar donor. Together this data confirms SGT1's role in vivo as the solanidine:UDP-galactose galactosyltransferase. (C) 2004 Elsevier Ireland Ltd. All rights reserved.

In soybean, a nitrogen-fixing species, both limitations are less likely than in crops lacking an N-fixing symbiont. Prior studies have used controlled environment or field enclosures where the artificial environment can modify responses to [CO2]. A soybean free air [CO2] enrichment (FACE) facility has provided the first opportunity to analyze the effects of elevated [CO2] on photosynthesis under fully open-air conditions. Potential ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) carboxylation (V-c,(max)) and electron transport through photosystem II (J(max)) were determined from the responses of A(sat) to intercellular [CO2] (C-i) throughout two growing seasons. Mesophyll conductance to CO2 (g(m)) was determined from the responses of A(sat) and whole chain electron transport (J) to light. Elevated [CO2] increased Asat by 15-20% even though there was a small, statistically significant, decrease in Vc,max. This differs from previous studies in that Vc,(max)/J(max) decreased, inferring a shift in resource investment away from Rubisco. This raised the Ci at which the transition from Rubisco-limited to ribulose-1,5-bisphosphate regeneration-limited photosynthesis occurred. The decrease in V-c,(max) was not the result of a change in gm, which was unchanged by elevated [CO2]. This first analysis of limitations to soybean photosynthesis under fully open-air conditions reveals important differences to prior studies that have used enclosures to elevate [CO,,], most significantly a smaller response of A(sat) and an apparent shift in resources away from Rubisco relative to capacity for electron transport.

Poly G tracts are longer, are greater in number, and show greater variability in C. upsaliensis than in the other species. Many genes involved in host colonization, including racR/ S, cadF, cdt, ciaB, and flagellin genes, are conserved across the species, but variations that appear to be species specific are evident for a lipooligosaccharide locus, a capsular ( extracellular) polysaccharide locus, and a novel Campylobacter putative licABCD virulence locus. The strains also vary in their metabolic profiles, as well as their resistance profiles to a range of antibiotics. It is evident that the newly identified hypothetical and conserved hypothetical proteins, as well as uncharacterized two- component regulatory systems and membrane proteins, may hold additional significant information on the major differences in virulence among the species, as well as the specificity of the strains for particular hosts.

They were investigated using dynamic mechanical analysis, scanning electron microscopy, tensile testing, FT-IR, oxygen permeability, and solubility studies. The films were found to have high modulus and strength values, with the properties depending strongly on composition. Glycerol was found to be effective as a plasticizer, and PVOH was shown to impart ductility to the pectin. Significant changes in morphology were seen with changes in composition by SEM. Hydrogen bonding of pectin in the film is affected by temperature and glycerol. Oxygen permeability of these films is much lower than found in commercial plastic films.

It could be possibly used as a coating, ink, fiber, adhesive, textile, chewing gums, cosmetic and biodegradable plastics. Thus, we sought to develop a methodology to chemically modify the zein structure so that zein mechanical properties can be manipulated. A method to prepare acyl derivatives of zein was developed. Zein was dissolved in dimethyl formamide (DMF) and acylated with anhydrides and acid chlorides. The reactions were done by reacting zein DMF solution with anhydrides at 70C or at room temperature with acid chloride. The amine/hydroxyl group of zein reacted to form ester/amide link. The structure was confirmed with proton NMR and IR spectra. These acetyl, benzoyl and butaryl amide/ester derivatives of zein were compression molded and their mechanical properties were measured. This study provided structure/mechanical property relationships for. these derivatives. It was found that chemical modifications by acetylation did have little impact on the mechanical properties. We also used dianhydrides to crosslink zein. At low level, i.e. 2-5% of dianhydrides zein showed significant improvement in tensile strength. When dianhydrides were used at higher level the products were crosslinked and insoluble. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Plant Polymer Res Unit, Peoria, IL 61604 USA.

In a survey of Walworth County seasonal home owners, most who work full time report they seldom work during vacations and weekends from their seasonal home. Yet there is a distinct subgroup who do mix work into weekends and vacations for a variety of reasons. The most frequent reasons given by these people for working from the seasonal home were related to the expectations of coworkers and clients. Understanding more about the habits and motivations of those who frequently work during weekends and on vacations could provide a new perspective on the obstacles everyone faces in balancing work and leisure.

In this paper, I explore some ideas from cognitive linguistics that might help us understand how people use the concept of nature. The concept of nature appears to have a radial structure, in which many different variations of meaning arise from a central, basic definition. The basic meaning of "nature" can be represented in a simple idealized cognitive model, which is mapped onto situations in various ways. Alternative definitions for a "natural" environment or system may be combined in a cluster model, giving rise to prototype effects. Recognizing that there is a common basis of meaning and a common conceptual structure underlying many different senses of the word "nature" may help us in understanding how people experience natural environments, and in communicating and negotiating new understandings of the human-nature relationship.

Two agency actions (prescribed fire and mechanical thinning) and two homeowner actions (defensible space and firewise construction) were analyzed against socio-demographic, situational and psychological precursors. Data were from a survey of Colorado residents (n = 532) living in the wildland-urban interface. Logistic regression indicated that the agency and homeowner actions had significantly different patterns of social causes and linkages. Results support the contention that socio-demographic, situational and psychological variables differentially influence support for agency or homeowner actions. Overall, the psychological measures were the most useful. Theoretically based models of natural resource policies can facilitate understanding the causal mechanisms that drive support for, or opposition to, wildland fire actions and improve policy development, situated communications and local community involvement strategies.

In 2004, the Zeltex AccuHarvest Analyzer was mounted on the clean grain elevator of a Case IH combine harvester and linked with GPS. The protein content of spring wheat was then measured and mapped in two dryland fields in northern Montana, USA. At the same time, grain samples were collected on the AccuHarvest during actual harvest and saved for whole grain laboratory analysis. Calibration results of linear regression showed sensor-based measurements of grain protein to be correlated with reference measurements of grain protein (R-2 = 0.86, SEP = +/- 0.49%). Grain protein could be predicted to within 0.66% when the calibration model was applied to a validation dataset. Interpolated maps of sensed- and referenced-protein were visually related. These results are sufficiently promising to suggest that on-combine spectroscopic sensing for mapping purposes is technically feasible. C1 USDA ARS, Pendleton, OR 97801 USA.

The study farms included 129 conventional and organic farms enrolled without regard to previous history of Salmonella infection. Herds were sampled at two-month intervals over a one-year period. Cattle groups more likely to be associated with Salmonella shedding (compared to preweaned calves) were cows designated as sick by farm personnel (OR = 2.5, 95% CI: 1.7, 3.7), cows within 14 days of calving (OR= 1.8, 95% Cl: 1.1, 2.8), and cows due for culling within 14 days (OR= 1.9, 95% CI: 1.0, 3.4). State of origin was also associated with the presence of Salmonella in samples from cattle and the farm environment; Midwestern states were more likely to have Salmonella-positive samples compared to New York. Cattle treated with antimicrobials within 14 days of sampling were more likely to be Salmonella-negative compared with nontreated cattle (OR= 2.0, 95% CI: 1.1, 3.4). Farms with at least 100 cows were more likely to have Salmonella-positive cattle compared with smaller farms (OR = 2.6, 95% Cl: 1.4, 4.6). Season was associated with Salmonella shedding in cattle, and compared to the winter period, summer had the highest odds for shedding (OR = 2.4, 95% CI: 1.5, 3.7), followed by fall (OR= 1.9, 95% CI: 1.2, 3.1) and spring (OR= 1.8, 95% CI: 1.2, 2.6). Environmental samples significantly more likely to be Salmonella-positive (compared to bulk tank milk) included, in descending order, samples from sick pens (OR = 7.4, 95% Cl: 3.4, 15.8), manure storage areas (OR = 6.4, 95 % Cl: 3.5, 11.7), maternity pens (OR = 4.2, 95 % Cl: 2.2, 8.1), haircoats of cows due to be culled (OR = 3.9, 95% Cl: 12, 7.7), milk filters (OR = 3.3, 95% Cl: 1.8, 6.0), cow waterers (OR = 2.8, 95% Cl: 1.4, 5.7), calf pens (OR = 2.7, 95% Cl: 1.3, 5.3), and bird droppings from cow housing (OR = 2.4, 95% Cl: 1.3, 4.4).

In order to determine the horticultural characteristics of these mutants, trees of four numbered selections (10-8,10-60,10-97 and 10-98) were propagated on four rootstocks (Swingle, Carrizo, Cleopatra mandarin, and sour orange) and field trials were established at two locations in Florida (Lake and Osceola Counties). Data have been collected over five harvest seasons (1994, 1995, 1996, 2002, 2003) on fruit yield and juice quality (color, soluble solids, and total acidity). Although fruit of each selection ripened during the typical midseason of other pineapple oranges, selections differed in fruit and juice quality characteristics. Three of the selections produced fruit with very few seeds and many fruit had no seeds. The low seed count could make theses selections much more valuable for the midseason fresh fruit market than the 'Pineapple' oranges that are presently available.

The system consisted of a cropping rotation in which nematode-resistant cover crops [cowpea (Vigna unguiculata (I.) Walp. cv. Iron Clay), velvetbean (Mucuna deeringiana (Bort.), Merr.) and sunn hemp (Crotalaria juncea L. cv. Tropic Sun)] were followed by a nematode-resistant tomato (Lycopersicon esculentum Mill.) crop. There were two cover crop treatments (cowpea and velvetbean) and a standard methyl bromide/chloropicrin (MC-33) treatment in 2000/01. A third cover crop treatment using sunn hemp was added in 2001/02. In 2003/04, two cover crop treatments (velvetbean and sunn hemp), a fallow (no cover crop), and a MC-33 treatment preceded by a summer sorghum sudangrass cover crop were used. Biomass production by the velvetbean, cowpea, and sunn hemp crops averaged 14.8, 8.5, and 11.6 Mg.ha(-1), respectively. Suppression of root-knot nematode (Meloidogyne incognita) by the cover crops could not be rigorously determined because of very low or low density nematode populations. Marketable tomato yields in all treatments and in all years were above average annual yields in Miami-Dade County. Yields were highest in 2003/04 because the crop was healthy and favorable prices encouraged eight harvests. In contrast, yields were low in 2001/02 due to a heavy infection by foliar pathogens. In 2000/01, there was no significant difference in extra-large fruit yield among the treatments but the MC-33 treatment had a higher yield of large fruits than the cowpea and velvetbean treatments, thus resulting in a higher total marketable yield than both cover crop treatments. The total marketable yield in the velvetbean treatment was next highest. In 2001/02, the cowpea treatment had a significantly higher yield of extra-large fruits than the MC-33 and the velvetbean treatments and significantly higher total marketable yield than all other treatments. In 2003104, equal marketable yields in all fruit-size grades occurred in the sorghum sudangrass/MC-33, velvetbean, and sunn hemp treatments and these were significantly higher than in the fallow treatment. Economic analysis showed that all treatments resulted in positive net returns in all years. Returns in 2003/04 were the highest of all study years due to high yields and high market prices. Among the cover crops, sunn hemp produced the highest tomato yields and net returns of all treatments over the two years it was used. C1 USDA, ARS, Nematol Lab, Homestead, FL 33031 USA.

AB The U.S. chocolate and confectionery industry is a major consumer of U.S. agricultural commodities. The industry uses over 3 billion pounds of sugar annually, much of it produced in Florida. Over 650 million pounds of milk and milk products, 322 million pounds of peanuts, 43 million pounds of California almonds and 1.7 billion pounds of corn syrup sweeteners are also used. The total value of these U.S. produced commodities is estimated to be over 1.5 billion USD and over 70,000 people are employed in this industry. The seed of Theobroma cacao L. is the only source of chocolate and the plant is not grown commercially in the U.S. Production of cacao in tropical America has been severely affected by two fungal pathogens causing diseases known as witches' broom (WB) and frosty pod (FP). These, along with another pan-tropical fungal disease, black pod (BP), were responsible for over 700 million USD in losses in 2001. Currently, WB and FP are confined to Central and South America; however, commercial populations in West Africa and South Asia are highly susceptible to both diseases. Traditional cacao breeding programs have only been marginally successful in producing resistant material with suitable commercial characteristics. In 1999, the USDA-ARS, in collaboration with MARS, Inc., initiated a project to apply modern molecular genetic techniques to cacao breeding. The objectives were to develop an international Marker-Assisted-Selection (MAS) breeding program focusing on disease resistance. International collaboration and the development of new disease resistant cultivars are ensuring that crop losses are manageable and contributing to a stable supply of cocoa beans for U.S. companies.
