AB A method is described for the determination of chromium and its enriched stable isotopes in human urine by isotope dilution mass spectrometry. A volatile chelate is formed with trifluoroacetylacetone (TFA) and the fragment ions corresponding to Cr(TFA)(2)(+) in the 356-360 m/z region are monitored. The chelate is thermally stable and exhibits no memory effects when isotope ratios change. The detection limit for the method is 0.03 ng of Cr/g, and the accuracy is verified by certified reference materials and by an independent method. The method is highly specific for chromium, due to the combined properties of the chelating agent, chromatographic column, and mass-specific detector. In addition to total chromium determinations, the method can also be used to quantitate enriched stable isotopes of chromium used as metabolic tags in tracer experiments in human nutrition studies.

AB By introducing heterogeneity indices, an empirical equation is proposed for characterizing the heterogeneity of non-isotropic fields. The formula is an extension of Fairfield Smith's (1938) empirical law describing heterogeneity in isotropic fields. Based on these indices, criteria are provided for choosing optimum plot shapes in terms of minimizing the sample variance and cost. Sample plots having their largest dimension in the direction with the largest index will give more accurate results (less variable) than plots with other shapes. Relations between the optimum plot size and relative cost versus variogram parameters are given for several variogram models. These relations indicate that variograms with small effective ranges have a very profound effect on the optimum plot sizes.

AB This paper briefly reviews the state of knowledge of the spatial and temporal variation of soil as discussed in the rejoinder session of the Pedometrics Workshop held in Wageningen, 1-3 September 1992. The paper discusses three aspects, namely theory, applications. and tools, in terms of current understanding and the research topics that we should be investigating in the next few years. Future directions for the study of soil variability are discussed in terms of issues for soil survey, issues for modelling, issues for methods and procedures, and finally, issues for effective communication of information about soil variability to users of soit data. An appendix of currently available geostatistical software is also included.

AB An antiserum raised against locustatachykinin I, one of four myotropic peptides that have been isolated from the locust brain and corpora cardiaca, was characterized by enzyme-linked immunosorbent assay (ELISA) and used for immunocytochemical detection of neurons and endocrine cells in the nervous system and intestine of the blowfly Calliphora vomitoria. The ELISA characterization indicated that the antiserum recognizes the common C-terminus sequence of the locustatachykinins I-III. Hence, the cross reaction with locustatachykinin TV is less, and in competitive ELISAs no cross reaction was detected with a series of vertebrate tachykinins tested. It was also shown that the antiserum recognized material in extracts of blowfly heads, as measured in ELISA. In high-performance liquid chromatography the extracted locustatachykinin-like immunoreactive (LomTK-LI) material eluted in two different ranges. A fairly large number of LomTK-LI neurons was detected in the blowfly brain and thoracicoabdominal ganglion. A total of about 160 LomTK-LI neurons was seen in the proto-, deuto-, and tritocerebrum and subesophageal ganglion. Immunoreactive processes from these neurons could be traced in many neuropil regions of the brain: superior and dorsomedian protocerebrum, optic tubercle, fan-shaped body and ventral bodies of the central complex, all the glomeruli of the antennal lobes, and tritocerebral and subesophageal neuropil. No immunoreactivity was seen in the mushroom bodies or the optic lobes. In the fused thoracicoabdominal ganglion, 46 LomTK-LI neurons could be resolved. The less evolved larval nervous system was also investigated to obtain additional information on the morphology and projections of immunoreactive neurons. In neither the larval nor the adult nervous systems could we identify any efferent or afferent immunoreactive axons or neurosecretory cells. The widespread distribution of LomTK-LI material in interneurons suggests an important role of the native peptide(s) as a neurotransmitter or neuromodulator within the central nervous system. Additionally a regulatory function in the intestine is indicated by the presence of immunoreactivity in endocrine cells of the midgut. (C) 1991 Wiley-Liss, Inc.

AB 1-Aminocyclopropane-1-carboxylic acid (ACC) synthase is a key enzyme regulating biosynthesis of the plant hormone ethylene, The expression of an enzymatically active, wound-inducible tomato (Lycopersicon esculentum L. cv Pik-Red) ACC synthase (485 amino acids long) in a heterologous Escherichia coli system allowed us to study the importance of hypervariable COOH terminus in enzymatic activity and protein conformation. We constructed several deletion mutants of the gene, expressed these in E. coli, purified the protein products to apparent homogeneity, and analyzed both conformation and enzyme kinetic parameters of the wild-type and truncated ACC syntheses. Deletion of the COOH terminus through Arg(429) results in complete inactivation of the enzyme. Deletion of 46-52 amino acids from the COOH terminus results in an enzyme that has nine times higher affinity for the substrate S-adenosylmethionine than the wild-type enzyme. The highly efficient, truncated ACC synthase was found to be a monomer of 52 +/- 1.8 kDa as determined by gel filtration, whereas the wild-type ACC synthase, analyzed under similar conditions, is a dimer. These results demonstrate that the nonconserved COOH terminus of ACC synthase affects its enzymatic function as well as dimerization.

AB The expression of constitutive and inducible cytochrome P450 forms was measured in cynomolgus monkey liver and compared with man, rat, mouse and hamster. Four alkoxyresorufin O-dealkylation (AROD) activities widely used as indicators of P450 induction were measured: methoxy-resorufin O-demethylation (MROD), ethoxyresorufin O-deethylation (EROD), pentoxyresorufin O-dealkylation (PROD) and benzyloxyresorufin O-dealkylation (BROD). In monkeys there were no sex-differences in untreated, phenobarbitone (PB)- or beta-naphthoflavone (BNF)-treated animals in AROD activities, or in individual P450 proteins detected by immunoblotting. Basal MROD and EROD activities varied by less than 7-fold between the five species, but the comparative pattern of basal MROD, EROD, PROD and BROD activities (the ''MEPB profile'') was very species-specific, with monkeys being similar to rats but different from man, mouse and hamster. The induction of AROD activities by PB and BNF was also highly species-specific. Monkeys expressed constitutive proteins immunorelated to the CYP1A, CYP2A, CYP2B, CYP2C and CYP3A sub-families (human CYP2A6 cross-reacted with the anti-rat CYP2B1 antibodies used, and so CYP2A and CYP2B forms could not be separately identified in the monkey). Single constitutive immunoblot bands were identified in monkey for CYP1A (54 kDa), CYP2A/CYP2B (51 kDa) and CYP3A (51 kDa), respectively, but two strong (51 and 52 kDa) plus two weak (49 and 49.5 kDa) bands were shown for CYP2C. Human liver expressed CYP1A2 (54 kDa), CYP2A6 (51 kDa), CYP3A4 (50.5 kDa) and three CYP2C9-immunorelated protein bands (48, 50 and 54 kDa). In monkeys BNF induced the 54 kDa CYP1A protein and CYP1A-dependent MROD, EROD and PROD activities (18-, 15- and 6-fold increases in activity, respectively), whereas PB strongly induced the 51 kDa CYP2A/CYP2B protein but did not induce PROD activity. PB also induced non-constitutive CYP2A/CYP2B protein bands at 49 and 52 kDa in some monkeys. BROD activity was induced less that four-fold by either PB or BNF in monkeys. In conclusion, cynomolgus monkeys expressed a range of constitutive CYP1A, CYP2A or CYP2B, CYP2C and CYP3A proteins similar to man, and a range of AROD monooxygenase reaction rates similar to both man and rat, but the basal MEPB profile of AROD activities in monkeys was more similar to rat than to man. MROD and EROD were good measures of CYP1A induction by polycyclic aromatic hydrocarbons in cynomolgus monkeys, but neither PROD nor BROD were indices of CYP2B induction by PB.

AB Various fluorescent substrates have been used as specific indicators of induction or activity of different cytochrome P450 isozymes in both fish and mammalian species. In an attempt to identify additional definitive fluorescent substrates for use in fish, we examined a series of 7-alkoxyphenoxazones, 7-alkoxycoumarins and 7-alkoxyquinolines as substrates in O-dealkylation assays with hepatic microsomes from rainbow trout (Oncorhynchus mykiss). Microsomes were prepared after 48 hr of treatment with beta-naphthoflavone (beta-NF), pregnenolone-16 alpha-carbonitrile (PCN), phenobarbital (PB), isosafrole (ISF), or dexamethasone (DEX). Total P450 spectra were obtained, and spectral binding studies were performed. Microsomal O-dealkylation rates were greater after ISF treatment than after beta-NF treatment for 7-methoxy-, 7-ethoxy-, 7-propoxy- and 7-benzyloxyphenoxazones but not for 7-butoxyphenoxazone. DEX treatment resulted in a significant elevation of pentoxyphenoxazone metabolism (about a 144-fold increase) compared with microsomes induced by beta-NF (11-fold) and ISF (37-fold). The rates of dealkylation of the alkoxyphenoxazones by ISF-treated microsomes occurred in the following order: methoxy > ethoxy > propoxy > benzxyloxy > butoxy > pentoxy. When beta-NF-treated microsomes were used, the 7-alkoxyphenoxazones were metabolized as follows: methoxy > ethoxy > propoxy > butoxy > benzyloxy approximate to pentoxy, while the order of metabolism of the 7-alkoxycoumarins was: ethoxy much greater than butoxy > propoxy approximate to methoxy > benzyloxy > pentoxy. None of the other treatments significantly increased the rate of metabolism of any of the alkoxycoumarins. Treatment with beta-NF did not significantly elevate the rate of metabolism of any of the alkoxyquinolines. DEX treatment produced significant elevations in the rate of metabolism of benzyloxy-, ethoxy-, and butoxy- approximate to pentoxy- approximate to propoxyquinoline, in that order. ISF treatment significantly elevated the rate of metabolism of benzyloxy-, methoxy- and butoxyquinoline, in that order. These results suggest that some of these new fluorescent substrates can be used to characterize induction of rainbow trout hepatic microsomal monooxygenase activity by ISF and DEX, in addition to the commonly used ethoxyphenoxazone and ethoxycoumarin for the characterization of induction by beta-NF or other 3-methylcholanthrene-type P450 inducers. Distinction between ISF-type and beta-NF-type inducers in rainbow trout hepatic microsomes may best be made using 7-methoxycoumarin as a substrate. Distinction between ISF-type and DEX-type inducers and between beta-NF-type and DEX-type inducers may best be made using 7-methoxyphenoxazone as a substrate. With beta-NF induction 7-methoxycoumarin, with ISF induction 7-methoxy- phenoxazone, and with DEX induction 7-ethoxyquinoline were metabolized to the greatest extent compared with controls and all other substrates tested.

AB In the western San Joaquin Valley, California, there has recently been emphasis on identifying suitable halophytes for irrigation with agricultural effluent and grown as crops using standard farming practices. Five perennial halophyte species belonging to the genus Atriplex (common name, saltbush) were established with fresh water, irrigated with saline drainage water, and mechanically harvested four times during the first 27 months of growth. Bale samples collected from three regrowth harvests were analysed for Selenium (Se), Boron (B), Sulfur (S), Iron (Fe), Zinc (Zn), Manganese (Mn) and Copper (Cu). The mean tissue concentrations for all species over regrowth harvests were 129 mg kg-1 dry weight for B and 0.6 mg kg-1 dry weight for Se. Tissue levels of B and S were above, and the remaining trace elements were below the maximum tolerable levels recommended for ruminants. All species showed trends of increased tissue B concentrations with cumulative age of plants. Over all the species the highest Se concentrations were measured in forage harvested 27 months after planting. The trace element composition of the harvested forage from this site does not appear to be a limiting factor when considering the use of Atriplex bales as a blend in animal feed rations.

AB Legumes can transfer significant amounts of symbiotically fixed N to neighboring plants, and a putative pathway for N transfer is decomposition of fine roots (those that are not secondarily thickened) and nodules. Our objective was to quantify the amount of N in living and dead roots and nodules of alfalfa (Medicago sativa L.) and birdsfoot trefoil (Lotus corniculatus L.). These values were used with estimates of root length and nodule numbers that decomposed during a season to estimate the size of this pathway of N transfer. Birdsfoot trefoil and effectively and ineffectively nodulated alfalfa were grown in root observation boxes filled with N-15-labeled topsoil (Typic Hapludolls). Roots and nodules were removed according to age and analyzed for total N and C. Specific N content of fine roots older than 2 wk was 0.22 mg N m-1 in alfalfa and 0.14 mg N m-1 in trefoil, and did not change with age. Specific N content did not decline in dead, nondecomposed roots of N2-fixing plants, indicating either that no significant N remobilization occurred or that N import equaled N export in these organs. Large, active birdsfoot trefoil nodules (>2 mm) had twice the N content of large active alfalfa nodules. Dead nodules, observed in birdsfoot trefoil only, had significantly lower N content than live nodules, indicating N remobilization during senescence. Fine roots contained up to 69% of N from fixation in alfalfa and 47% in birdsfoot trefoil, and nodules contained 89% and 94% fixed N, respectively. We conclude that alfalfa releases more N through decomposing roots than nodules, whereas birdsfoot trefoil contributes more N to the soil through decomposing nodules than roots, but neither process could account fully for published estimates of N transfer.

ID MAIZE
AB The plant growth regulator ethephon has been used to reduce height and lodging of intensively managed corn (Zea mays L.).  However, the impact of ethephon-induced changes in vegetative growth on water use and grain yield of corn grown at various densities under drought stress conditions has not been widely studied.  Field studies were conducted for 2 yr in semiarid eastern Colorado to determine if foliar ethephon application can alter vegetative growth and water use and promote drought stress resistance of corn. In 1989, treatments consisted of a factorial combination of two irrigation levels (low and high), two plant densities (53 333 and 80 000 plants ha-1), and five ethephon treatments (0, 0.28, 0.56, and 0.84 kg ha-1, applied at the 6- or 8-leaf growth stage) at one site. In 1990, treatments consisted of a factorial combination of four plant densities (24 700, 37 045, 49 390, and 61 735 plants ha-1) and three ethephon rates (0, 0.28, and 0.56 kg ha-1 applied at the 6-leaf stage) at two sites. Plant height, leaf area index (LAI), dry matter yield, cumulative evapotranspiration (ET), and grain yield were measured. In both seasons, ethephon application reduced plant height and LAI by 10 to 40%, relative to the control, and this resulted in early season ET reductions. Ethephon application either had no effect or decreased yields in 1989 under all irrigation and plant density treatments, because of a lack of significant drought stress. However, when drought occurred in 1990, ethephon application decreased yields at low plant densities but enhanced yields at high plant densities at both locations, with a maximum 37% yield increase for the intermediate ethephon rate. Our data indicate that ethephon application has the potential for improving resistance to drought in corn.

AB Cheatgrass (Bromus tectorum L.) is an undesirable nonnative annual that germinates at relatively low temperatures in the spring and fall and can establish a root system more quickly than Great Basin native perennial grasses. The purpose of this study was to determine whether seed priming could be used to enhance low-temperature germination rate of native perennial grasses so that they can better compete with cheatgrass. A matric-printing technique was used to increase low-temperature germination rate of seven native perennial grasses: bluebunch wheatgrass [Pseudoroegneria spicata (Pursh) Love], thickspike wheatgrass [Elymus lanceolatus (Scribn. & J.G. Smith) Gould; syn. Agropyron dasystachyum (Hook.) Scribn.], basin wildrye [Leymus cinereus (Scribn. and Merr.) A. Love], sheep fescue (Festuca ovina L.), canby bluegrass (Poa canbyi Scribn.), sandberg bluegrass (Poa sandbergii Vasey), and bottlebrush squirreltail [Sitanion hystrix (Nutt.) J.G. Smith]. Seeds primed at both 10 and 25-degrees-C were evaluated for germination response at both 10 and 25-degrees-C. Days to 50% germination (D50) was almost-equal-to 4 d for cheatgrass germinated at 10-degrees-C. Native grass seeds in control treatments germinated between about 4 and 11 d later than cheatgrass at 10-degrees-C. Priming reduced D50 by between 4 and 8 d for all native species when germinated at 10-degrees-C. Germination rate at 10-degrees-C was generally higher when the seeds were primed at 25-degrees-C, except for basin wildrye. Priming increased cold temperature germination rate of bluebunch wheatgrass, thickspike wheatgrass, and sheep fescue to a level comparable to cheatgrass.

TI TILLAGE EFFECTS ON DRYLAND WHEAT AND SORGHUM PRODUCTION IN THE SOUTHERN

ID WATER STORAGE; GRAIN-SORGHUM; STRAW-MULCH
AB Winter wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] are important, well-adapted grain crops for the semiarid southern Great Plains. They often are grown in rotation on dryland to reduce the risk of failure associated with annual cropping and to overcome the low precipitation-use efficiencies associated with crop-fallow systems. This study on Pullman soil (Torrertic Paleustoll) determined the effects of 12 tillage systems ranging from no-tillage (herbicides only) to sweep tillage (no herbicides) on water storage and use, crop growth, yields, and yield components for dryland wheat and sorghum grown in rotation. Tillage systems did not affect mean water storage during fallow nor mean water use by either crop. All yield, growth, and yield component factors differed among growing seasons. Wheat grain and straw yields were not affected by tillage. Mean wheat grain yield was 2.92 Mg ha-1. Mean sorghum grain yield was greatest (3.91 Mg ha-1) for the system of reduced tillage after sorghum and no-tillage after wheat, and least (3.48 Mg ha-1) for the system of reduced tillage after each crop. Sorghum stover yields were not affected by-tillage. Number of panicles harvested was greatest (233 000 ha-1) and least (212 000 ha-1) for the same treatments that resulted in the greatest and least grain yields. Sorghum seed weights and test weights were not affected by tillage. This study showed that a wide range of tillage systems is adaptable for a dryland wheat-grain sorghum cropping system for the semiarid southern Great Plains.

TI NITROGEN-FERTILIZER REQUIREMENTS IN AN ANNUAL DRYLAND CROPPING SYSTEM
SO AGRONOMY JOURNAL

ID WINTER-WHEAT; WATER
AB Reduced tillage systems in the Central Great Plains have improved precipitation storage efficiency and increased the potential to crop more intensively than with the traditional crop-fallow system. More intensive cropping will require additional N input to maintain economical yields. Nitrogen fertility requirements for optimum crop yields in a dryland, annual cropping system were studied. Six N fertilizer rates (0, 22, 45, 67, 90, and 134 kg N ha-1) were applied to the same plots for 8 crops on a Weld silt loam (montmorillonitic, mesic Aridic Paleustoll). Spring barley (Hordeum vulgare L.), com (Zea mays L.), and winter wheat (Triticum aestivum L.) were grown in rotation from 1984 through 1991. Although grain yields varied with crop and year, average annual grain production was 2108, 2683, 3162, 3459, 3382, and 3411 kg ha-1 for the above N rates, respectively. This included 1 yr of zero yield, when a corn crop was lost due to hail, and 1 yr of low barley yields due to heat and water stress at anthesis. This compares with annualized winter wheat yields of 1381 kg ha-1 yr-1 produced in an adjacent crop-fallow system with adequate applied N. Application of 67 kg N ha-1 each crop year or, based on regression analysis, an average available N (soil plus fertilizer) supply of 170 kg N ha-1 was sufficient to optimize (95% of maximum) grain yields over the 8-yr period. These results indicate a high potential for adopting more intensive dryland cropping systems in the Central Great Plains to increase water use efficiency and better maintain soil quality.

AB Long-term effects of cropping systems on soil properties, such as organic soil C and N levels is necessary so more accurate projections can be made regarding the sequester and emission of CO2 by agricultural soils. This information can then be used to predict the effects of cropping systems on both soil degradation, maintenance, or improvement and global climate changes. My objective was to evaluate the effects of crop rotation and N fertilizer management on changes in total soil C and N concentrations that have occurred during an 8-yr period in a long-term study, in the Western Corn Belt. Seven cropping systems (three monoculture, two 2-yr, and two 4-yr rotations) with three rates of N fertilizer were compared. Monocultures included continuous corn (Zea mays L.), soybean [Glycine - (L.) Merr.], and grain sorghum [Sorghum bicolor (L.) Moench]. The 2-yr rotations were corn-soybean and grain sorghum-soybean, and the two 4-yr rotations were corn-oat (Avena sativa L.) + dover (80% Melilotus officinalis Lam. and 20% Trifolium pratense). grain sorghum-soybean and corn-soybean-grain sorghum-oat + clover. Soil samples were taken in the spring both in 1984 and 1992 to a depth of 30 cm in 0- to 7.5-cm, 7.5- to 15-cm, and 15-to 30-cm increments. No differences were obtained in 1984, but both rotation and N rate significantly affected total soil C and N concentrations in 1992. The results indicate that C could be sequestered at 10 to 20 g m-2 yr-1 in some cropping systems with sufficient levels of N fertilizer. Greater storage of C in soils suggests CO2 emissions from agricultural soils could be decreased with improved management practices and may in the long term have a significant effect on CO2 in the atmosphere under current climate conditions.

AB Small-grain stand establishment in research plots of the summer rainfall region of South Africa is a problem because of dry surface soil. A vacuum system plot planter was developed to meet these requirements. The planter has simple adjustments for changes in species, cultivars, seeding rate, row spacing, and fertilizer rate. The precision planter has fertilizer times and modified planter units. Uniform stands are achieved with most species at seeding rates varying from 5 to 100 kg ha-1 (4.5-89.0 lb acre-1), with no restriction in plot length. The unit is easily transported and can plant in excess of 80 5-m (16.5 ft) plots h-1.

ID COMPONENTS; TRITICUM; NITROGEN; WHEATS; GROWTH
AB Very little information exists on crop yields in antiquity. Examination of some of the earliest yield records may give some insight about crop productivity among ancient peoples and a historical perspective on the progress achieved in modern agronomic practices. The Book of Genesis contains one of the earliest recorded expressions of a concern for the yielding potential of cultivated crops. In this paper, we translate the ambiguous biblical reference to crop yield into a modern expression of crop yield per unit land area. Because the yield aspirations of these ancient people are equivalent to modern yields achieved under rainfed conditions at the same location, we undertook an analysis of the agronomic practices used by these ancient people to determine the likelihood that such yields could be achieved. In fact, it appears possible that maximum cereal yields in the ancient Middle East could have approximated modern yields. This analysis may highlight the great advances in modern agriculture to bring high crop yields to large land areas by overcoming various stresses, but the inherent physiological yielding potential may not have been substantially altered over the millennia.

   CLIMATE; MODEL
AB During the last 12,000 to 30,000 years, a large proportion of the dominant trees and shrubs in modern assemblages of woodland and shrub steppe vegetation in the northwestern Great Basin have undergone relatively small changes in their geographic ranges. A woodland tree, Juniperus osteosperma, has an extensive temporal and spatial fossil record from 11 woodrat midden locales that were sampled in the northwestern Great Basin. Above 1,300 m elevation, J. osteosperma has been continuously present in that fossil record for at least the last 30,000 years. However, J. osteosperma was lost at elevations below 1,300 m sometime during the last 10,000 years, during the Holocene. Although the elevational ranges of six shrub taxa show changes during the Holocene, geographic ranges of 11 other shrub taxa have been largely static. Of the woodland and shrub steppe species examined, Pinus monophylla has experienced the greatest change in its geographic range during the late-Pleistocene and Holocene. Pinus monophylla has migrated northward across the Great Basin from Pleistocene refugia in the southern portions of this region. The rate of latitudinal migration was more rapid along the eastern side of the Great Basin than on the western side. Thus, the species that comprise modern woodland and shrub steppe communities of the northwestern Great Basin appear to have two strategies to cope with climate change. First are species, as exemplified by J. osteosperma, whose geographic ranges were relatively insensitive to climate change and are termed orthoselective species. High genetic variation within species and the formation of coenospecies likely allowed these species to cope with climatic change by genetic adaptation. Secondly, other species, as exemplified by P. monophylla, have experienced shifts in their geographic range during past climate changes and more clearly fit the migration model of species response to climate change.

AB Determinations of total body water (TBW) calculated from deuterium dilution spaces and bioelectrical-impedance measurements were made serially in a group of 15 women before, during, and after pregnancy. Similar measurements were made once in a group of 50 nonpregnant women and intermittently in another group of 10 women during pregnancy and postpartum. TBW increased significantly during pregnancy, then decreased postpartum. Estimates of TBW in pregnancy and postpartum calculated with models derived from nonpregnant and pregnant women were similar to measured values. Changes in reactance and resistance explained more of the variance in predicting changes in TBW than did body weight, abdominal circumference, or hematocrit (50-75% vs 4-50%, respectively). Changes in TBW estimated with the nonpregnancy impedance model were significantly different than either the measured changes or changes predicted with the pregnancy impedance model. These findings indicate that the impedance method is a practical and valid method for determining longitudinal changes in TBW.

AB Absorption of calcium and its mobilization from bone during lactation are important for delivery of calcium to breast-feeding infants; whether calcium intake offsets bone resorption is not known. We hypothesized that calcium absorption is increased in lactation and greater in women on low calcium diets, resulting in similar rates of bone resorption and accretion. Calcium absorption and kinetic indexes were calculated by using two stable isotopic tracers in 8 women; 6 were studied both during lactation and nonlactation. Women consumed low calcium diets, with half receiving supplemental calcium. Intestinal absorption was related to serum 1,25-dihydroxyvitamin D and did not increase during lactation. Despite decreased urinary calcium excretion during lactation, especially in women with low calcium intake, net balance tended to be lower during lactation. Mean residence time decreased and bone resorption exceeded accretion in almost all lactating women. Calcium need for milk production appears to be met by decreased urinary excretion and increased bone resorption, and not by increased intestinal absorption.

AB Incomplete processing of progastrin expressed by human colon cancer cells: role of noncarboxyamidated gastrins. Am. J. Physiol. 266 (Gastrointest. Liver Physiol. 29): G459-G468, 1994. - Gastrin is mitogenic for several colon cancers. To assess a possible autocrine role of gastrin in colon cancers, we examined human colon cancer cell lines for expression of gastrin mRNA and various forms of gastrin. Gastrin mRNA was not detected in the majority of colon cancer cell lines by Northern hybridization but was detected in all human colon cancer lines by the sensitive method of reverse transcriptase-polymerase chain reaction (PCR). Gastrin mRNA was quantitated by the competitive PCR method. The majority of cell lines expressed very low levels of gastrin mRNA (< 1-5 copies/cell); only one cell line expressed > 20 copies/cell. The mature carboxyamidated form of gastrin was not detected in any of the cell lines by radioimmunoassay or immunocytochemistry. Results suggested that either gastrin mRNA expressed by colon cancer cells was altered (mutated) or posttranslational processing of progastrin was incomplete. Gastrin cDNA from all the colon cancer cell lines had an identical sequence to the published sequence of human gastrin cDNA. Specific antibodies against precursor forms of gastrin were used, and significant concentrations of nonamidated (glycine-extended) and prepro forms of gastrin were measured in tumor extracts of representative colon cancer cell lines. The presence of precursor forms of gastrin suggested a lack of one or more ofthe processing enzymes and/or cofactors. Significant concentrations of the processing enzyme (peptidylglycine alpha-amidating monooxygenase) were detected in colon cancer cells by immunocytochemistry. Therefore, lack of other cofactors or enzymes may be contributing to incomplete processing of precursor forms of gastrin, which merits further investigation. Since low levels of gastrin mRNA were expressed by the majority of human colon cancer cell lines and progastrin was incompletely processed, it seems unlikely that gastrin can function as a viable autocrine growth factor for colon cancer cells. High concentrations of glycine-extended gastrin-17 (GG) (> 10(-6) M) were mitogenic for a gastrin-responsive human colon cancer (DLD-1) cell line in vitro. It remains to be seen if GG or other precursor forms of gastrin are similarly mitogenic in vivo, which may then lend credibility to a possible autocrine role of gastrinlike peptides in colon cancers.

AB The microscopic brush herder membrane adherence assay was used to determine resistance (nonadherence) and susceptibility (adherence) of Chinese pigs (n = 289) to the K88ac(+) strain of Escherichia coli-mediated disease. This study estimates prevalence of resistance to diarrheal disease in multiple family lines (no common ancestry for a minimum of 3 generations) for the Chinese Meishan, Fengjing, and Minzhu breeds. Results of in vitro assays indicate that pigs of the Meishan breed are highly resistant (nonadherent) to K88ac(+) E coli-mediated disease. The gene conferring susceptibility to K88ac(+) E coli-mediated disease exists at low frequency in pigs of the Minzhu breed. Minzhu-type (crossbred) pigs of both phenotypes (susceptible and resistant) were identified in ratios consistent with a 1-locus gene model. Given that all susceptible pigs were from 1 site, frequency of susceptibility within this Minzhu population is estimated at 8%. Inheritance within the Fengjing breed is still unclear because a weakly adherent phenotype, as well as the resistant. phenotype, was identified. The weakly adherent phenotype was observed in pigs derived from multiple family lines. Expression of the weakly adherent phenotype in terms of susceptibility to disease is not known at this time.

AB Direct evidence linking alkaloids found in endophyte-infected tall fescue forage with the livestock disorder known as fescue toxicosis is lacking. Physiologic effects of fescue toxicosis include reduced serum prolactin concentration in cattle. A monoclonal antibody specific to the lysergic moiety of ergot alkaloids was developed in mice after creating an immunogen by linking lysergol to human serum albumin. The antibody was specific to the lysergic moiety and, therefore, it cross-reacted with ergot alkaloids, lysergic acid, and lysergol. The antibody did not cross-react with allkaloid derivatives that had bromated or hydrogenated lysergic ring moieties. Fescue toxicosis conditions were elicited in yearling Angus steers by permitting them to graze endophyte-infected tall fescue containing > 650 mu g/kg of ergo-valine for 60 days. Passive immunization of steers by infusion of the monoclonal antibody increased serum prolactin concentration by 7 ng/ml, beginning immediately after infusion. Control steers did not respond to treatment with bovine serum albumin. Active immunization of yearling Angus heifers with immunogens containing lysergol or ergonovine linked to human serum albumin resulted in an antibody response.

AB Supercritical fluid extraction (SFE) using CO2 has been demonstrated as an alternative to polar organic solvents or water for the quantitative removal of atrazine, two of its metabolites, cyanazine, and metolachlor for several agricultural soils. Recoveries of each analyte from soil fortified from 0.1 to 2.0 mg/kg ranged between 25 and 120%, depending upon the soil matrix and analyte extracted. A single extraction, using cosolvent-modified CO2, conducted at relatively high fluid density in both static and dynamic modes, sufficed for all analytes. Principal component analysis was used to correlate each component in a matrix of dependent variables influencing extraction efficiency. HPLC analysis indicated that fewer coextracted moieties are found using SFE rather than from extractions using polar liquid solvents. Addition of both water and methanol to the air-dried soil prior to commencement of CO2 flow does enhance the recovery for all analytes. Further, such cosolvents do not promote the conversion of the chloro-triazine analytes to any of their corresponding hydroxy or methoxy analogs under the SFE conditions tested.

AB Sterile insect releases of a pupal color-based genetic sexing strain of the Mediterranean fruitfly, Ceratitis capitata (Wiedemann), were made during the summer and fall of 1991 in coffee plantations in Kauai, HI. Four treatments compared with respect to trap recapture and sterility rates induced in native populations were: (1) genetic sexing strain (almost-equal-to 99% males = males only), (2) genetic sexing strain (males and females), (3) genetic sexing strain (high % female female), and (4) standard strain (males and females). Each week either 2 liters (almost-equal-to 120,000) of irradiated pupae for the bisexual populations or 1 liter of irradiated pupae for the unisexual populations were dye-marked and ground released in buckets. Adult flies emerged and dispersed throughout individual (almost-equal-to 1 ha) coffee fields. Flies were trapped weekly in standard dry traps or in liquid protein traps. Coffee berry samples were collected weekly to determine egg sterility rates, and females trapped in liquid protein were dissected for presence of sperm and sperm type. A new technique was developed to type sperm as either sterile (irradiated) or wild in mated females. An estimate of sterile fly competitiveness based on relative degrees of egg hatch suppression indicated an overall three- to five-fold increase in competitiveness of the males-only strain compared with the standard bisexual strain. Significantly, however, this difference even widened to a qualitative degree by the end of the test.

AB Large numbers of winterform pear psylla, Cacopsylla pyricola Foerster, leave the pear orchard in the fall, overwinter in diapause in nonpear habitats, and return to pear orchards the following spring. Postdiapause development of overwintering forms, including oogenesis and mating (indicated by spermatophore numbers in females), was more advanced in early spring for insects collected from pear than for those collected from apple, a nonhost but an important species for overwintering. These results were confirmed by caging psylla on pear and apple in the field and laboratory. Psylla were also caged on a number of ornamental species in fall, and mortality and postdiapause development were monitored. Some insects, with the exception of those placed on a dead pear tree, survived the winter on all plant species. Postdiapause development on most species lagged behind that on pear. Psylla collected from pear trees on the orchard perimeter were often less advanced than those collected from the orchard interior, suggesting that psylla tended to colonize orchard edges. These effects were most pronounced in orchards and during years in which reentry rates were highest. Ovarian development of psylla was similar in insects removed from yellow sticky traps and from clear sticky traps. Females removed from yellow traps had more spermatophores than those removed from clear traps on two sampling dates.

High yields of saccharification could be maintained even at substrate concentrations as high as 22-23%, but the rates of solubilization and saccharification decreased 2-3-fold. We also tested the fermentability of these hydrolysates by the yeast Saccharomyces cerevisiae, which revealed the presence of inhibitory compounds. These compounds could be removed by the filtration of hydrolyzed peel. Successful fermentations of filtered hydrolysates were achieved after pH adjustment with calcium carbonate.

Although the majority of available data indicates that circulating Lp(a) levels are under strict genetic regulation, there is some evidence that this parameter may be subject to dietary modification as well. The effects of dietary fat saturation on plasma Lp(a) levels and hepatic apolipoprotein(a) (apo(a)) mRNA abundance were examined in ten unrelated cynomolgus monkeys which were fed each of three experimental diets enriched in saturated (SAT), monounsaturated (MONO), or polyunsaturated (POLY) fatty acids in a crossover design consisting of three 13-week periods. Each diet contained 30% of calories as fat with 0.1% dietary cholesterol by weight and differed solely by the isocaloric substitution of fatty acids as 60% of total fat calories. The mean Lp(a) level for these animals during the SAT diet (13.4 +/- 2.4 mg/dl) was significantly greater as compared with those observed during the MONO (8.6 +/- 2.2 mg/dl, P < 0.0003) and POLY (9.3 +/- 2.1 mg/dl, P < 0.002) diets, while the difference noted between the MONO and POLY diets was nonsignificant. Hepatic apo(a) mRNA abundance was decreased in these animals during the MONO diet relative to both the SAT and POLY diets, with only the difference between the SAT and MONO diets achieving statistical significance (P < 0.02). Our data demonstrate that the substitution of dietary SATs with either MONOs or POLYs result in significant reductions of Lp(a) levels in these monkeys. However, only the MONO diet significantly decreased hepatic apo(a) mRNA levels relative to the SAT diet, suggesting that dietary MONOs and POLYs may differ in the manner by which they regulate plasma Lp(a) levels.

AB A honey bee (Apis mellifera) queen mates with about ten haploid drones, thus producing colonies composed of about ten subfamilies of super-sisters. An increasing but controversial body of literature supports the views that: (1) Members of each subfamily within a colony can recognise each other, and distinguish super-sisters from half-sisters. (2) Members of each subfamily use this recognition information and increase the reproductive fitness of their own subfamily at the expense of half-sisters through behaviour termed nepotism. A mathematical model is developed that shows that task specialisation by subfamilies, and bees that repeatedly undertake the behaviour within subfamilies, can influence the numbers of interactions among super-sisters, relative to the numbers of interactions between half-sisters. The model is then evaluated using a data set pertaining to trophallaxis behaviour in a two-subfamily colony. It is concluded that with this data set, task specialisation and subfamily recognition were indeed confounded, suggesting that the apparent subfamily recognition could easily have been an artefact of task specialisation.

AB In a recent hypothesis [Selhub and Miller (1992) Am. J. Clin. Nutr. 55, 131-138], we proposed that homocysteinaemia arises from an interruption in S-adenosylmethionine's (AdoMet) coordinate regulation of homocysteine metabolism The present study was undertaken to test a prediction of this hypothesis, that homocysteinaemia due to folate deficiency results from impaired homocysteine remethylation due to the deficiency and impaired synthesis of AdoMet, with the consequent inability of this metabolite to function as an activator of homocysteine catabolism through cystathionine synthesis. Rats were made folate-deficient by feeding them with a folate-free amino-acid-defined diet supplemented with succinyisulphathiazole. After 4 weeks, the deficient rats exhibited a 9.8-fold higher mean plasma homocysteine concentration and a 3.2-fold lower mean hepatic AdoMet concentration compared with folate-replete controls. Subsequent supplementation for 3 weeks of the folate-deficient rats with increasing levels of folate in the diet resulted in graded decreases in plasma homocysteine levels, accompanied by graded increases in hepatic AdoMet levels. Thus plasma homocysteine and hepatic AdoMet concentrations were inversely correlated as folate status was modified. In a second experiment, the elevation of plasma homocysteine in the deficient rats was found to be reversible within 3 days by intraperitoneal injections of ethionine. This effect of ethionine is thought to be exerted through S-adenosylethionine, which is formed in the liver of these rats. Like AdoMet, S-adenosylethionine is an activator of cystathionine beta-synthase and will effectively promote the catabolism of homocysteine through cystathionine synthesis. In crude liver homogenates of the rats treated with ethionine, cystathionine beta-synthase activity was 3-fold higher than that measured in homogenates from vehicle-treated controls.

AB Leaves and bark of a wide range of Prunus species were surveyed for the presence of coumarins. Hemiarin was found in leaves of all three species (P. mahaleb, P. pensylvanica, P. maximowiczii) previously reported to contain this compound, but the bark of P. maximowiczii contained scopolin. Hemiarin was also found in the leaves of P. maackii and P. cerasus cvs. Montmorency and Northstar, but the bark of these species contained only scopolin. Scopolin, and sometimes scopoletin, occurred in the bark of P. cyclamina, P. nipponica var. kurilensis, P. serotina, P. verecunda, P. virginiana and three grafted cultivars of P. avium ('Bing', 'Black Tartarian', 'Lambert) but not in P. avium seedlings. The inheritance of scopolin in bark was determined in control-pollinated interspecific progenies of P. cyclamina, P. maackii P. nipponica var. kurilensis, and P. verecunda. The inheritance of herniarin in leaves was determined in several MXM (Mahaleb X Mazzard) root-stocks and a few other progenies.

HK-l1, HK-l2 and HK-l3 were found only in the immature stages. HK-l1 and HK-l2 are monomorphic. Gene duplication is suggested for the polymorphic locus HK-l3 with two-band homozygotes and four-band heterozygotes. The Africanized honey bee specific proteins were not found in the larval or pupal stage of Africanized honey bees. In the adult, they were weakly present in the head, present in the thorax and absent in the abdomen.

AB Candida guilliermondii was evaluated for compatibility with commercial citrus coatings for application to heat-treated grapefruits (Citrus paradisi Macf.) and biological control of Penicillium digitatum. Although constituents of many coatings were fungicidal, FMC 705 and FMC 214 (FMC Corp., Lakeland, FL) and Nature Seal (USDA product) were satisfactory carriers for the yeast. Candida guilliermondii survived for 2 months at 13-degrees-C within films of dried coatings on filter paper disks. When applied to grapefruits in FMC 705 or Nature Seal at concentrations calculated to produce initial surface populations of 10(4) or 10(6) cfu/cm2, the populations stabilized over 9 weeks at 13-degrees-C between 10(5) and 10(6) Cfu/CM2.  Populations of unidentified, native Candida species on fruits were originally 3 x 10(2) cfu/cm2 before a 3-h quarantine treatment in air at 48-degrees-C reduced them to 2 x 10(1). Although these low native populations on heated fruits subsequently rebounded over 9 weeks to levels approximately      10(4) Cfu/CM2,  fruits to which C. guilliermondii was applied remained free of decay 12 to 20% longer in cold storage than fruits not treated with this species.

AB Nealiolus curculionis (Fitch) is a univoltine, solitary, endophagous larval parasitoid of the sunflower stem weevil, Cylindrocopturus adspersus (LeConte), in both cultivated and native sunflower. This parasitoid represented 96% of all parasitoids attacking the weevil from 1980 to 199 1. Adult parasitoids were active in the field from late June to late August (1980-1985). Eggs were deposited in early instar weevils feeding within the sunflower stem. The immature parasitoids overwintered in diapausing weevil larvae in the sunflower stem. Parasitization of overwintering sunflower stem weevil larvae varied from 5 to 32% (1980 to 1991). Adult parasitoids emerged in early June through mid-July, which was earlier and more rapid than the emergence of their host. Postdiapause development of N. curculionis required 31 days after the parasitoid larvae exited the weevil larva for adult eclosion. Parasitoid males and females lived 9 days in the laboratory when supplied with honey as a food source. Results indicated that overall parasitization has increased from levels reported in the late 1970s and early 1980s. The parasitoid appears to be a consistent mortality factor in the population dynamics of the sunflower stem weevil in cultivated sunflower, though the adult populations are often low.

AB The mesquite cutworm, Melipotis indomita (Walker). is the major defoliator of mesquite in central Texas. In the laboratory, the cutworm larvae developed normally on honey mesquite (P. glandulosa Torrey var. glandulosa) and the Argentine vinal (P. ruscifolia Grisebach). Velvet mesquite (P. velutina Wooton), western honey mesquite (P. g. var. torreyana (Benson) Johnston), the Mexican P. laevigata (H. and B. ex. Willdenow) Johnston and P. juliflora (Swartz) DC, and the Argentine P. flexuosa DC were slightly less suitable hosts. Larvae developed occasionally on a natural hybrid of the Argentine P. alba Grisebach from Tucson, Arizona, but not on a commercial P. alba hybrid developed in southern Texas. Larvae did not develop on the two screw-bean mesquites tested (P. pubescens Bentham and P. reptans Bentham var. cinerascens (A. Gray) Burkart) or on 12 other species of woody legumes from central Texas, although an occasional larva fed for a few days on some of them. Among 11 species of mostly tropical leguminous trees tested, larvae developed and produced adults normally on manila tamarind (Pithecellobium dulce (Roxburgh) Bentham) and one adult was produced on monkeypod (Samanea saman (Jacquin) Merrill). In a biological control program, the mesquite cutworm would complement the damage from other foliage feeders that could be introduced from South America. It could be a candidate for introduction into other countries where mesquite has become a pest, provided that a foliage feeder were the type of control agent wanted.

AB A Trichomalopsis sp. near americana was colonized from eastern Nebraska and was evaluated for its potential as a biological control agent against house flies. Maturation within the host puparium required 13 days at 30-degrees-C and 16 days at 25-degrees-C. Essentially no maturation occurred at 20-degrees-C, and 10 days at 20-degrees-C was sufficient to induce arrested development in the third instar in about 67% of the parasites. Trichomalopsis sp. is gregarious and prefers to oviposit repeatedly on single hosts even when other hosts are readily available. Females are capable of producing 10-12 eggs per day and a total of about 110 eggs when adequate hosts and a carbohydrate source are available. This species is not considered to have high potential as a biological control agent because of its preference to sting only 2-3 hosts per day, its relatively low fecundity, and its low incidence in nature.

(Coleoptera: Cucujidae) was determined. Each sex of the predator was evaluated in experimental arenas with and without shelled corn to determine the role of prey species and habitat in predation. Its rate of predation on a given prey species was measured by exposing a single predator to one of eight prey densities (2, 4, 8, 12, 16, 24, 32, and 40) in a 118-ml glass arena over a 24-h period. Both sexes of the predator showed a typical Type II functional response, with the Holling disk equation as an acceptable model, for all three prey species in both corn and noncorn situations. Analysis of variance for the entire experiment indicated that prey density contributed significantly to predator response (P = 0.0001), and that females killed more prey than males, but this was marginally significant (P = 0.07). Both sexes showed a higher response when corn was absent and both showed differential responses to prey species. The relative response of females to prey was P. interpunctella > T. castaneum > O. surinamensis, whereas the response of males was P. interpunctella > O. surinamensis > T. castaneum. Instantaneous rate of prey discovery did not differ among treatments, indicating that search strategy was less important than handling time in predatory response.

AB There is considerable interest in the use of coal combustion byproducts as soil liming materials in agricultural production, but there is concern that such use may be detrimental to the quality of agricultural soils. To evaluate these byproducts as liming materials and address issues related to soil quality, we compared the influence of different amounts of four combustion byproducts [fly ash and bed ash from a fluidized bed combustion furnace, lime-injected multistage burner residue, and spray dryer residue] and CaCO3 on soil pH and activities of urease, phosphatase, arylsulfatase, and dehydrogenase in an acidic soil. Studies comparing the influence of the combustion byproducts and CaCO3 on soil pH showed that on a weight basis of application, substantial differences were observed in the ability of these materials to influence soil pH but that such differences decreased markedly after the data were transformed to a CaCO3 equivalent basis of application. Analysis of covariance for these transformed data indicated that whereas the liming abilities of fly ash and CaCO3 were not significantly different when compared on the CaCO3 equivalent basis, those of bed ash, multistage burner residue, and spray dryer residue were less than that of CaCO3. Studies comparing the influence of the byproducts and CaCO3 on soil enzyme activities showed that the effect of these liming materials on the enzyme activities studied was largely due to their influence on soil pH. The relationships obtained between soil pH and enzyme activities in soil amended with the liming materials generally demonstrated the marked similarities in the influence of the combustion byproducts and CaCO3 on these activities when observed within the domain of soil pH. These studies showed that the combustion byproducts tested functioned as soil liming materials in a manner similar to that of CaCO3 and seemed to have little adverse effect on soil quality.

AB The three-parameter Weibull density is commonly used to model the distribution of tree diameters in forest stands. We demonstrate, through likelihood profiles, that maximum likelihood estimation is often inappropriate for data from young trees due to negative estimates of the location parameter. We suggest a Bayesian model and fit it, using the Gibbs sampler, to three data sets. The latter model is easy to implement and guarantees a positive estimate for the location parameter. We illustrate some novel forms of model diagnostics, demonstrating that the Bayesian model is appropriate for two of the data sets, while it is dubious for the third. A sampling-resampling method shows that the lack of fit of the model for the latter data set is due to the likelihood, and not the prior specification.

ID BIOTYPE-C GREENBUGS; RDNA GENE FAMILY; RIBOSOMAL DNA; DISTRIBUTIONS
AB The intergenic spacer region of the rRNA cistron was used as a molecular fingerprinting probe to study clonal diversity in Schizaphis graminum (Rondani). A high degree of clonal diversity was found in overwintering populations on wheat from Kansas, Texas and Oklahoma. Out of 184 individuals tested, 132 unique maternal lineages were identified. Overall, clonal diversity of overwintering populations was no less than in spring and summer populations. However, in some fields there were more instances where individuals of the same genotype were identified. By partitioning the total population diversity into various sampling components (fields, counties and states), 93.1% of the total diversity was found among individual S. graminum within fields. Overwintering of many genetically distinct clones as parthenogenetic morphs is one mechanism by which clonal diversity is maintained in populations of S. graminum. The incidence of clonal diversity further substantiates the importance of the S. graminum holocycle for generating genetic heterogeneity in the USA.

ID EVAPOTRANSPIRATION
AB The surface energy balance directly affects vertical gradients in temperature and specific humidity within the atmospheric surface layer, and these gradients influence optical turbulence. This study was conducted to improve current understanding of the partitioning of energy at the ground surface of a bare soil field and its influence on the character and intensity of optical turbulence as represented by the refractive index structure parameter, C-n(2), and to improve micrometeorological models of the surface energy balance. The field study entitled ''Radiation Energy Balance Experiment for Imagery and Electromagnetic Propagation'' was conducted by the United States Army Atmospheric Sciences Laboratory and the United States Department of Agriculture Agricultural Research Service, at Bushland, Texas, during May and July 1992. The following were collected: diurnal radiation; evaporation (directly measured by large weighing lysimeters); five-level micrometeorological profiles of wind speed, air temperature, and relative humidity; soil temperature and volumetric water content; soil heat flux; optical turbulence (scintillometer); and near- and far-field infrared imager data over wet and dry bare soil for clear and cloudy sky conditions. Initial results from the modeling efforts indicate excellent agreement between measured and modeled values of radiation/energy balance fluxes and C(n)-2, for one day. Future model evaluation will extend over the wide range of conditions encountered during the field study.

AB The effects of ozone and simulated acid rain on the aboveground nutrient composition of loblolly pine (Pinus taeda L.) seedlings were studied in a 2-year open-top chamber experiment in the Piedmont of North Carolina. Multivariate analysis of variance tests indicated significant ozone response in the 2nd year but no significant simulated acid rain effect in either year. No interaction among treatments was detectable. Seedlings responded to increasing ozone exposures with increasing concentrations of nitrogen, phosphorus, potassium, magnesium, and calcium in the stem, branches, and foliage. The response of increased nutrient concentration was associated with decreased total biomass accumulation. The nutritional responses were most prominent in late season flushes of foliage and are probably related to ozone-induced premature abscission of early-season flushes. High nutrient concentrations in the stem, branches, and late-season flushes of trees exposed to elevated ozone levels suggest retranslocation and slower growth rates resulted in better aboveground nutrient status and lower nutrient demand from the soil.

AB Stand structure and crown architecture of loblolly pine (Pinus taeda L.) spacing trials in Hawaii and South Carolina were examined for attributes that would explain markedly different stockabilities (stand density per mean stand DBH), respectively, 1740 and 850 trees/ha at a quadratic mean stand DBH of 25 cm. In plots spaced at 2.4 X 2.4 m, these stockabilities produced 604 m3/ha at age 25 in Hawaii, and 297 m3/ha in South Carolina. Data collected in these stands indicate that stockability differences were associated with differences in tree size-class structure, crown length, and leaf area. Both stands were characterized by a two-tiered height structure, but the crown bases of trees in the subdominant class in Hawaii extended 1-2 m below the bases of the crowns of the dominant height class. In the South Carolina stands the crown bases of both height classes were at the same level. Green crown lengths in Hawaii were 4-7 m longer than in South Carolina, and the associated crown leaf area of 63.9 m2 was five times greater. The differences in stockability was attributed to the Hawaiian site and climate, which provide a long growing season, high solar radiation, high sun angle, favorable temperatures, and a favorable soil moisture regime and foliage nutrient status, and to a lack of significant insect and disease pests. The influence of genotype on stockability was not testable with these data.

AB To determine the response of seedlings lifted in fall and stored at temperatures below 0-degrees-C until outplanting, ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings from two Oregon seed sources were harvested in September, October, and November (stored below 0-degrees-C until late winter-spring planting) and compared with seedlings lifted in March (stored above 0-degrees-C until planting). Growth potential at the time of planting was measured by monitoring changes in root initiation, fresh weight, and root starch concentration and content under greenhouse conditions. Field performance was determined by measuring survival and growth at two field sites. Dry weight and root starch decreased 5-1 3% and 82-99%, respectively, in storage, and the majority of change occurred during the first 3 months of storage. Less than 15% of the seedlings from the September lifting and storage treatment initiated new roots, and fresh weight decreased more than 30% during the greenhouse test. Seedlings from this treatment had less than 25% field survival during the 1st and 2nd years after outplanting. Greater than 62% of seedlings lifted in late fall and spring had new roots; these seedlings exhibited less than 14% loss in fresh weight, and greater than 75% field survival. In the greenhouse test, initial root starch concentration was not related to subsequent root growth (new root weight or days to root initiation). Similarly, neither initial root starch concentration nor content at the time of planting was strongly associated with field survival or growth in the field after planting.

AB Esters of sterols and cinnamic acid derivatives (CAD) comprise a group of compounds found in seeds of, among others, corn, wheat, rye, triticale, and rice.  They have been implicated in lowering blood lipid levels.  Related compounds are antioxidants and others inhibit fungal spore germination.  To obtain pure compounds for bioactivity studies with corn insects and kernel-rotting fungi, an improved method of separating these compounds was developed.  A high-performance liquid chromatography method, using a mixture of acetonitrile, n-butanol, acetic acid, and water (94:3:2:1, v/v), improved the resolution of steryl esters of CAD isolated from corn bran, which shows that this group of compounds is at least twice as complex as was previously reported.  A simple method for hydrolysis and joint determination of the CAD and sterol portions of the ester is described.  A total of 16 compounds that appear to be steryl CAD are reported along with relative retention times and composition percentages.  Sitosteryl, sitostanyl, stigmasteryl, campesteryl, campestanyl and DELTA7-sitosteryl, and DELTA7-campesteryl ferulates were identified in corn bran.  Mass spectrometry data for the trimethylsilyl derivatives of the sterols esterified to ferulic and p-coumaric acids are given.  In addition to known p-coumarates, campesterol and DELTA7-campestenol forms were also found.

AB Corn at 30% moisture was air-dried at 25-100-degrees-C.  Drying times to 12% final moisture ranged from 1 hr at 100-degrees-C to 38 hr at 25-degrees-C.  Chemical composition was unchanged by drying temperature.  Increasing drying temperature decreased test weight, germination, nitrogen solubility index, and it increased kernel breakage susceptibility and percentage of floating kernels.  Because breakage susceptibility, but not stress-cracking, increased upon high-temperature drying, some chemical or physical change other than stress-cracking in the kernel cell-wall matrix or in the starch granules may have affected breakage susceptibility.  Isoelectric focusing showed decreasing protein bands at pI 4.0-6.6 as corn-drying temperature increased from 70 to 100-degrees-C.  Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that protein with molecular weights of 21,000-97,000 decreased after treatment at 70-degrees-C; they cannot be observed in corn dried at 85-100-degrees-C.  Prolamin levels also decreased as air-drying temperature increased.  Thus, corn density, breakage susceptibility, and germination may change upon drying because of changes in albumins and prolamins.  These relationships may provide new or improved methods for identifying grain that is damaged or of lower quality due to high-temperature drying.

AB In a survey of U.S. and Canadian breads, urethane, a chemical shown to be carcinogenic in animals, was detected at low levels in 22 batches of commercial breads and rolls that were sampled immediately after baking.  The mean level of urethane was 2.06 +/- 0.2 ppb for measurements on composite samples of 12 loaves prepared using established procedures for trace nutrient analysis.  The mean value of urethane was less than one third the 7-ppb value used by others to estimate probable nonalcohol human dietary exposure to urethane.  Based on the newly determined mean level for urethane and bread consumption data, the per capita dietary intake per year in the United States is 47 +/- 4 mug for untoasted bread.  Chemically specific gas-chromatographic detectors employing either high-resolution mass spectrometry or methane chemical-ionization mass spectrometry were used for all measurements, yielding a quantification precision of +/- 0.2 ppb at the l-ppb level.  The average recovery of urethane from white bread was 110% in the 3-7 ppb range.

ID INSTRUMENTAL MEASUREMENT; DOUGH CONSISTENCY
AB Eight soft red winter wheats were commercially milled into straight-grade flours and shipped to five large baking companies. The companies used proprietary commercial formulations to produce wire-cut and rotary-molded cookies and chemically leavened crackers from each flour. All commercial products were evaluated for hardness at our laboratory. Hardness values were compared relative to the flours used and the baking company that produced the cookies and crackers. The relative contribution of each flour to product hardness across products and companies was remarkably consistent considering differences among commercial products. For all three products, the highest protein flours consistently produced the hardest products. Product hardness was relatively inconsistent in products made from flours with intermediate protein levels. Data show that the contribution to product hardness of various soft wheat flours is a strong quality attribute, especially when associated with elevated protein concentration. Thus, the texture of several soft wheat products of one company and the texture of products from many companies could be influenced by one flour.

TI CHEMICAL-PROPERTIES INFLUENCING RATE OF RELEASE OF STARCH ENCAPSULATED

ID MIDWESTERN UNITED-STATES; ATRAZINE; ALACHLOR; WATER
AB Starch encapsulation is a controlled release technology which may reduce a chemical's environmental contamination potential. Effectiveness of starch encapsulation in modifying environmental fate is not uniform for all herbicides. We quantified the time required for complete release of herbicides encapsulated in unmodified cornstarch (amylopectin:amylose ratio approximately 3:1) by an extrusion process. These herbicides exhibited a range of chemical properties. Time required for complete release of herbicides, encapsulated using this technology, was strongly correlated with water solubility of the encapsulated chemical.  As water solubility of the encapsulated chemical decreased, time required for complete release increased exponentially. Results of field scale experiments suggests that starch encapsulation influences the environmental fate of an encapsulated herbicide when the time required for complete release is from 14 to 21 days. Results suggest that starch encapsulation will provide a satisfactory rate of release for herbicides that have water solubilities of 20 to 300 mg l-1.

AB The purpose of the present study was to identify antigens of the protozoan parasite Neospora caninum that could be used for the diagnosis of neosporosis in domestic animals. As revealed by immunoblotting, immune sera from a wide range of animal species exhibited a similar recognition pattern of four major and several minor N. caninum antigens. In contrast to preinoculation sera, all tested immune sera recognized nonreduced immunodominant 17-, 29-, 30-, and 37-kDa antigens. A 46-kDa protein which showed faint recognition by preimmune sera also exhibited a strong response by immune sera. Immunolocalization of the four immunodominant N. caninum antigens was investigated by immunogold electron microscopy using monospecific polyclonal antisera. The 17-kDa antigen appears to be associated,vith the body part of the rhoptries, while the 29- and 30-kDa antigens were associated with the dense granules, network, and limiting membrane of the parasitophorous vacuole. Studies were also conducted to compare antibody responses to N. caninum and the related protozoan Toxoplasma gondii. Although N. caninum and T. gondii (RH strain) tachyzoites shared a Pew cross-reacting antigens, the immunodominant antigens of both parasites were not recognized by heterologous sera. Also, immunogold staining with rabbit anti-Neospora hyperimmune serum exhibited almost no labeling of external membranes of Neospora tachyzoites compared with the very marked labeling seen when Toxoplasma tachyzoites (RH strain) were incubated with rabbit anti-Toxoplasma hyperimmune serum. These unique antigenic differences should be useful in developing a diagnostic assay for N. caninum.

AB Two experiments were conducted with broiler chickens to determine various nutritional effects on neurotransmitter metabolism. In Experiment 1, 21-day old chickens were fasted for 24 hr, fed on an ad libitum basis, fed a diet containing 450 g crude protein/kg (high-protein) or fed a diet containing 80 g crude protein/kg (high carbohydrate) to examine nutritional regimens that may alter neural factors regulating growth. Chickens were injected (250 mg/kg BWt) with a tyrosine hydroxylase inhibitor, alpha-methyl-DL-rho-tyrosine (AMPT), to inhibit catecholamine synthesis and to estimate turnover constants as functions of these treatments. In Experiment 2, 7-day old chickens were fed diets containing 120, 180, 240 and 300 g crude protein and 1 mg T-3/kg diet for 21 days to determine the effects of both dietary protein and thyroid status on catecholamine concentrations. Norepinephrine (NE) and dopamine (DA) in the brains and NE and DA in the hearts and pancreases were separated by HPLC and determined by electrochemical detection. Fractional turnover of DA in the brains of both fed and fasted chickens was equal but was over twice as great as that of NE. Fractional NE turnover in hearts of both fed and fasted chickens was 12.3%/hr although fractional NE turnover in pancreas was greater (P < 0.05) in fasted than in fed chickens (9.0%/hr vs 5.1%/hr). These same rate constants were also seen in brains of chickens fed high-carbohydrate or high-protein diets. In contrast, a protein diet increase pancreatic and cardiac NE turnover compare to a high-carbohydrate diet.

GABA levels increased between the pupal (1-4.1%) and adult worker stages. Taurine levels increased from 3.9% in larval brains to 6.5% in major workers. Brain concentrations of biogenic amines (dopamine, octopamine, noradrenaline and serotonin) increased between larval and adult stages. The possible relationships between neurochemical parameters and age polytheism are discussed.

AB A mechanical tissue chopper was used to obtain liver explants (35-75 mg) from 2-3-week old turkeys to determine both tissue sensitivity and metabolic effects of adrenergic agonists (isoproterenol, propranolol, norepinephrine and phenoxybenzamine). A previously noted catecholamine induced decrease in in vitro lipogenesis in chicken liver explants was also noted in turkey liver explants. Thus, one set of control points for in vitro regulation is under control of the cAMP system. Preincubation of slices (1 hr) with propranolol blocked the inhibition of lipogenesis caused by alpha and beta-adrenergic agonists (arterenol or isoproterenol) during a subsequent 1-hr incubation. Preincubation of slices with either of these agonists decreased lipogenesis even following an extensive washout. Inhibition could be overcome with propranolol, a beta adrenergic antagonist.

ID AEGILOPS-SQUARROSA; HEXAPLOID WHEAT
AB In order to diversify the genetic base of resistance in hard red winter wheat (Triticum aestivum L.) to leaf rust (caused by Puccinia recondita Rob. ex Desm.), five genes for resistance were transferred from the diploid goatgrass T. tauschii (Coss.) Schmal. to hexaploid wheat lines. One of the derived lines, KS90WGRC10, had a very low infection type when inoculated with 23 cultures of P. recondita. The others, KS91WGRC11, KS92WGRC16, U1865, and U1866, had low to intermediate infection types with three cultures. Their infection types varied similarly to those of lines carrying previously transferred alleles of Lr21. WGRC10 carries a completely dominant gene, Lr41, on chromosome ID that segregates independently of any other T. tauschii-derived leaf rust-resistance genes. WGRC11 carries the partially dominant gene, Lr42, also on 1D, that is linked to Lr21 with a recombination value of 0.286 +/- 0.023. WGRC16 carries a partially dominant gene, Lr43, that segregates independently of all known genes for seedling resistance from T. tauschii; its chromosome location is not known. The genes carried by U1865 and U1866 are allelic to Lr21. WGRC10, WGRC11, and WGRC16 have been released as germplasms by the Wheat Genetics Resource Center.

TI MODIFIED RECURRENT SELECTION FOR BARLEY YELLOW DWARF VIRUS TOLERANCE IN
   WINTER-WHEAT
SO CROP SCIENCE
LA English
DT Article
AB Barley yellow dwarf virus (BYDV) causes an economically important disease of small grains. We evaluated tolerance to BYDV in a winter wheat population resulting from modified recurrent selection. Chemical hybridizing agents (CHAs) were used to facilitate recombination, and selection was based on tolerant genotypes producing more seeds under disease pressure. Seventeen parents, selected for BYDV tolerance, were mated in a partial diallel, with equal amounts of seed from F1 plants constituting the original population. Bulked seed from F1 plants was planted in rows in the field. Female rows were sprayed with a CHA (either RH-007 or MON 21200) and inoculated with BYDV-PAV-IL. Seed was harvested from female rows. Our objectives were to determine if BYDV tolerance increased over cycles, if plant height and heading date were affected by the selection scheme, and if environmental effects were greater than genotypic effects for symptom expression. For evaluation, the original parents and S1:2 lines from Cycles 2, 3, and 4 were planted in paired hills (one hill in each pair was inoculated with BYDV) in a randomized complete block design. The experiment was repeated With S2:3 lines. No consistent improvements occurred over cycles in early or late disease ratings or yield of inoculated hills. Stunting was reduced from 6.0% in the parent population to 0.8% in Cycle 3 in the S2:3 lines. In comparison with Cycle 2, average heading date in Cycle 4 was delayed by about 2 d. The modified recurrent selection scheme used was not effective in increasing the level of tolerance to BYDV, perhaps because of the limited genotypic variability among the parents, or the use of indirect selection for the number of seeds produced under disease pressure rather than BYDV symptoms.

AB The nucleo-cytoplasmic interactions of common wheat (Triticum aestivum L.) with two of its relatives [T. macha L. and Triticum dicoccoides (Koern. ex Asch. & Graebner) Aarons.] were studied to determine the effect of the foreign cytoplasm on agronomic traits. Two high-yielding, semidwarf spring cultivars were crossed reciprocally with one cytoplasm source each of T. macha and T. dicoccoides to produce four populations with both alloplasmic random lines and euplasmic random lines. Previous reports on these cytoplasm sources were based on the performance of backcross lines in which the recurrent parents were low-yielding, normal height cultivars released in the 1950s and 1960s. Between 30 and 60 random F4-derived F6 lines from all populations were grown in five environments in Minnesota from 1986 through 1988. Grain yield, days to head emergence, and plant height were measured in each environment. No significant differences were detected between alloplasmic lines and euplasmic lines for the measured traits in any population. This was in contrast to an earlier report that T. macha cytoplasm increased grain yield in the backcross lines of an old normal height cultivar. Diversity for cytoplasm apparently caused little or no change in normal agronomic performance when using these sources of alien cytoplasm.

   MATTER
AB Knowledge of heritability and inheritance of nutritive quality traits in intermediate wheatgrass [Thinopyrum intermedium (Host) Barkw. & D.R. Dewey] would be helpful in choosing effective selection techniques. This study assesses variation and heritability of traits associated with hay quality in intermediate wheatgrass, ascertains the relative magnitude of general and specific combining ability (SCA and GCA) for these traits, and examines relationships among important agronomic and quality traits. Six parent clones and the 15 progenies from a diallel cross (reciprocal crosses not included) were evaluated in a replicated field test for in vitro digestible organic matter (IVDOM), neutral detergent fiber (NDF), and N concentration of whole plants, leaf blades, and stems (stem plus leaf sheath). Spike emergence date, plant height, and leaf/stem ratio were also measured. Variation among progenies was significant for all traits except leaf IVDOM and whole-plant N. Leaf/stem ratios varied from 0.22 to 0.28 among progenies, with stems contributing more to whole-plant IVDOM than did leaf blades. Low variation in whole-plant N concentration limits the potential for forage N improvement. Spike emergence date, a measure of relative plant maturity, was correlated positively with IVDOM (r = 0.75**) and negatively with NDF (r = -0.61*). Narrow-sense heritability estimates were moderately high for whole-plant IVDOM and for IVDOM, NDF, and N of stem and leaf fractions. Variance components for GCA were generally higher than those caused by SCA. Year effects for IVDOM and NDF were high, but year x GCA and year x SCA interaction effects for these traits were not significant. Selection for high whole-plant IVDOM in a single environment employing recurrent phenotypic selection or other selection techniques that utilize additive genetic variance should be effective in improving digestibility of intermediate wheatgrass hay.

AB Sorghum [Sorghum bicolor (L.) Moench] stores starch as the principal nonstructural carbohydrate in grain, but primarily stores sucrose in stem. The extent of sucrose accumulation in stem varies among cultivars, and has been previously related to decline in activities of soluble sucrose-degrading enzymes in sweet sorghum stem. The hypothesis that soluble sucrose-degrading activity would vary inversely with patterns of sucrose accumulation was tested in panicles and stems of five diverse sorghum genotypes grown and sampled in the field from boot to post-black layer. Activities were greater in panicle than stem during inflorescence development, and invertase activities remained relatively greater in panicle during grain filling than in stem during sucrose accumulation. Panicle invertases were speculated to hydrolyze sucrose prior to endosperm import. In contrast, invertase and sucrose synthase activities were already low by the period of sucrose accumulation in stem regardless of the stem sucrose-accumulating abilities of the studied genotypes. A follow-up greenhouse study tested for parallel changes in levels of activity and mRNA for sucrose synthase, and provided evidence that activity was regulated by pretranslational control. In this study also, sucrose accumulated after sucrose synthase activity and mRNA levels were already low. A decline in soluble sucrose-degrading activities appears to be a prerequisite for, but cannot explain the extent of, accumulation of sucrose in stem.

AB Carbon isotope discrimination (DELTA) shows promise for estimating water-use efficiency (WUE, grams dry weight/gram water transpired) in C3 crop species. The objective of this study was to determine if variation for DELTA is present in diverse alfalfa (Medicago sativa L.) germplasm, and if DELTA is correlated with direct measurements of WUE. Eighteen alfalfa accessions originating from 13 countries were established in 1990 in irrigated and dryland environments at Central Ferry, WA, in a fine-silty, mixed, mesic Typic Natrixeroll soil. Significant differences among accessions for leaf DELTA were observed with no significant environment x accession interaction. Based on 1990 results, high DELTA (PI 420400, 20.3 parts per thousand), middle DELTA (PI 522242, 19.7 parts per thousand), and low DELTA (PI 434600, 18.9 parts per thousand) accessions were selected for additional field evaluation in 1991. For the dryland environment in 1991, leaf DELTA of PI 434600 was lower than PI 420400, but accession differences were not observed in the irrigated environment. In greenhouse pot studies, accessions did not differ for total plant WUE. But shoot WUE values all differed significantly, and were 2.43, 2.09, and 1.73 g dry wt./kg transpiration for the low, middle and high DELTA accessions, respectively. Total plant WUE was correlated with DELTA only under drought stress (r = -0.55**, n = 30), but shoot WUE and DELTA were correlated within well watered (r -0.63**, n = 30) and drought-stressed (r = -0.73**, n = 30) treatments. Correlations between shoot WUE and root:shoot values were negative and significant at P = 0.01, suggesting that root/shoot carbon partitioning influenced shoot WUE. Results show reproducible variation for DELTA in alfalfa germplasm, and that DELTA is potentially useful for evaluating alfalfa germplasm for WUE.

AB The number of stems produced by cool-season forage grasses is a major factor in determining forage production. Knowledge of factors that influence stem numbers will be useful in developing proper management practices. Objectives of this study were to (i) determine total stem numbers and the amount of far-red (FR) and red (R) light at the crown level in canopies of crested wheatgrass [Agropyron desertorum (Fisch. ex Link) Schultes], western wheatgrass [Pascopyrum smithii (Rydb.) Gould], and smooth bromegrass (Bromus inermis Leyss.) that were hayed, grazed, or ungrazed; and (ii) evaluate the relationship between the FR/R ratio at plant crown level and stem numbers. The study was conducted during 1989, 1990, and 1991 at Mandan, ND, USA. Management practices produced differences in both FR/R ratios and stem numbers. Treatment effects on stem numbers were consistent over years for smooth bromegrass whereas treatment x year interactions were significant for crested wheatgrass and western wheatgrass. Generally, stem numbers were greatest for all species that were hayed followed in order by grazed and ungrazed treatments. Grazed and ungrazed plants developed longer leaves and stem internodes than did hayed plants. The relationship between FR/R ratio and stem numbers for all treatments was consistent with previous reports that stem numbers of grasses may be influenced by the FR/R ratio at the crown. The decline in stem numbers of ungrazed stands suggests that to maintain vigorous stands of these species requires an appropriate level of management.

TI REPRODUCTIVE-RESOURCE ALLOCATION IN RHIZOMA PEANUT

ID ENERGY ALLOCATION; STRATEGIES
AB Partitioning of energy reserves between sexual (flower and seed) and asexual (rhizome) reproduction in rhizoma peanut (Arachis glabrata Benth.), a perennial, tropical-forage legume, appears to be affected by environmental stress. If so, seed production may be enhanced by manipulating the growing environment. To investigate this possibility, the effect of defoliation frequency on the energy-allocation balance of sexual vs. asexual reproduction of rhizoma peanut was determined. Four defoliation frequencies (nondefoliated, weekly, every 4 wk, and every 8 wk) were imposed on 'Florigraze' rhizoma peanut. Aboveground and rhizome biomass were sampled prior to treatment initiation (6 June 1988 and 15 June 1989) and every 4 wk until frost (24 wk in 1988 and 16 wk in 1989). During the first 8 wk, aboveground biomass of the nondefoliated treatment nearly doubled. Concurrently, aboveground biomass of all defoliated treatments remained the same or declined. Rhizome biomass of all treatments declined during the same period but in most cases, recovered by the latter part of the growing season. Generally, aboveground biomass ranked (P < 0.05) 1 wk < 4 wk less-than-or-equal-to 8 wk < nondefoliated, and rhizome biomass ranked (P < 0.05) 1 wk = 4 wk = 8 wk < nondefoliated. Flowering was synchronous for all treatments, but sexual reproductive effort constituted <0.5% of total-plant biomass because seeds were never produced. Defoliation positively affected (P < 0.05) both flower dry matter (DM) production and sexual:asexual ratio with treatments generally ranked nondefoliated = 1 wk < 4 wk = 8 wk. This study indicates that the partitioning of energy to sexual or asexual reproduction in rhizoma peanut can be altered in response to stress.

TI RELATIONSHIPS BETWEEN VEGETATIVE GROWTH-RATE AND FLOWER PRODUCTION IN

ID NITROGEN; PLANTS; YIELD
AB The physiological factors that regulate flower production are not well understood for flax (Linum usitatissimum L.) and other field crops, in spite of the fact that flowers are directly related to seed yield through the fruits that form from them. The objective of this research was to relate total flower production (FTOTAL), length of the flowering period (FPERIOD), and flower production rate (FRATE) of flax to (i) growth rates in several environments, and (ii) plant characteristics measured before and during the flowering period. Growth, flower production, seed yield, and the components of yield of 18 genotypes representing three plant types were measured in five plantings (18 May 1984; 1 May 1989; and 2, 10, and 29 May 1990) at Brookings, SD. Differences in growth, flower production, and yield were large for the five plantings and small for genotypes grouped by plant type. Length of the vegetative period and concentration of N in the tissues at midbloom or last flower were the only traits with significant positive correlation for all three flower production traits and all three plant types. Consideration of growth in shorter periods in three plantings showed that associations with FRATE, FPERIOD, and FTOTAL were negative for the vegetative period and positive for the flowering period for most plant characteristics. Factors producing significant statistics in multiple regression with flower production traits included leaf weight or growth in leaf weight, length of the vegetative period, N concentration, total nonstructural carbohydrate (TNC) concentration, and stem weight. Path coefficient analyses for FRATE, FPERIOD, and FTOTAL revealed indirect effects through leaf and stem growth rates for length of the vegetative period and N concentration. We conclude that FRATE, which had been considered to be a growth function relating vigor during flowering to seed yield at harvest, may be adversely affected by rapid vegetative growth, and that similar effects may occur for FPERIOD and FTOTAL.

DT Article
ID POD SET; DETERMINATE; ABSCISSION; CULTIVARS; ABORTION
AB Flowers are directly related to seed yield through the fruits that form from flowers, but the physiological factors that regulate flower production after induction of the flowering state are not well understood for soybean [Glycine max (L.) Merr.], where the connection of flowering to yield is complicated by abortion of potential fruits. The objectives of this research were to (i) evaluate methods of obtaining flower count data and characterizing flowering in terms of rate of flower production (FRATE), duration of flowering (FPERIOD), and total flowers (FTOTAL) in soybean genotypes differing in numbers of flowers and levels of reproductive abortion; (ii) determine relationships between these characteristics and seed yield; and (iii) measure effects of plant factors on the flowering characteristics when both plant growth and flowering are altered by variation in planting date. Growth and flowering were measured in five plantings during 2 yr at Brookings, SD in Vienna (fine-loamy, mixed Udic Haploboroll) soil, using cultivars Dassel and Corsoy 79, which have few flowers per raceme, and the many-flowered lines SD87001 and IX93-100. Flowering was measured by counting blossoms three times weekly throughout the bloom period (Method 1) and by counting fruits and abscission scars for aborted flowers 2 wk after final blossoming (Method II. Cumulative flowering curves determined by Method I were closely fit by the logistic function. Total flowers by Method I was lower than by Method II, but only minor differences were observed between methods for detecting flowering differences caused by planting date or genotype. Flowering traits measured by Method I accounted for 60 to 77% of the variation in seed yield. Genotypes differed markedly in the relationship of plant characteristics to flowering traits, but rate of increase in height in vegetative stage generally had significant negative correlation to FPERIOD, had positive correlation to FTOTAL and FRATE, and was identified as one of several factors that had major influence on flowering traits. It is concluded that large and rapidly growing soybean plants tend to have short FPERIOD with high FRATE and FTOTAL, but genotypes also may have additional traits that determine flower production characteristics.

ID WINTER-WHEAT
AB Negative effects of preharvest sprouting on wheat (Triticum aestivum L.) baking quality are well known, but limited information is available on field performance of sprouted seed and plants grown from sprouted seed. Field trials were seeded with 'Stephens' soft white winter wheat in 1989 and 1990 near Pendleton, OR, to determine the effects of sprouting severity (Trials 1 and 2), and seeding depth, and fungicide seed treatment (Trials 3 and 4) on emergence, growth, development, and yield of plants from sprouted seed. A sprouting-severity score was developed as follows: A = no visible sprouting, B = partial embryo exposure, C = full embryo exposure, and D = physically damaged embryo. Emergence and early crop growth were not affected when sprouting was not visible (A), but were significantly reduced when embryos were fully exposed (C) or damaged (D). Emergence and early seedling growth were reduced in proportion to sprouting severity of the seed. Carboxin + thiram [5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-carboxamide + bis(dimethylthiocarbamoyl)disulfide] seed treatment had negative effects on stands produced from sprouted seed with fully exposed embryos, but these results were not consistent from year to year. Grain yield of plants grown from sprouted seed was not different from that of normal seed except when embryos were damaged (D). In seeding depth and seed treatment experiments, sprouted seed produced poorer stands and early growth than normal seed only in Trial 3. Treating sprouted seed with carboxin + thiram further reduced stands and growth in Trial 3. Sprouting did not affect seedling emergence and vigor in Trial 4 probably because the seed was less severely sprouted. Grain yield of plants produced from sprouted seed was not influenced by seed treatment in Trials 3 and 4. Shallow seedings produced better stands and yield than deep seedings, regardless of seed quality. The sprouting-severity score has potential in evaluating sprouted seed lots for use as seed wheat.

ID GENETIC DIVERSITY
AB The Asiatic or A-genome cottons, Gossypium arboreum L. and G. herbaceum L., are potentially important genetic resources for cotton breeding programs. The National Plant Germplasm System (NPGS) contains approximately 400 accessions of these species, but little information is available on the diversity within the collection or on characteristics of individual accessions. This investigation was initiated to provide a morphological description of each accession. These data were used to evaluate the range of diversity represented within the collection and to address the questions of species and race distinctions. Multivariate techniques were used to assess similarities among accessions and to evaluate morphological parameters contributing to the variation in each species. Means for 41 of 53 characters were significantly different between species, although high infraspecific variability resulted in range overlap for all characters. Principal component analysis separated the two species. Accessions from southern Africa and racial designations of africanum and wightianum formed clusters within G. herbaceum based on the first two principal components; no clusters were noted within G. arboreum. Accordingly, the validity of infraspecific or racial classifications for most of the accessions of this latter species in the current NPGS collection is questionable. Additional germplasm acquisitions from under- or non-represented areas could expand genetic diversity in the collection.

TI OMEPRAZOLE AS AN ADJUVANT TO ANTIMICROBIAL THERAPY FOR ERADICATION OF
   HELICOBACTER-PYLORI INFECTION

AB The first therapies to reliably eradicate Helicobacter pylori used combinations of bismuth, metronidazole, and tetracycline or amoxicillin. The increasing frequency of metronidazole resistance, however, has limited the effectiveness of the original combination therapies. As with the use of bismuth compounds, proton pump inhibitors can be used to kill H pylori but are themselves insufficient to eradicate the infection. Proton pump inhibitors markedly increase gastric pH. Because this action may make antimicrobials more effective, we evaluated omeprazole as an adjuvant to antimicrobial therapy. We tested omeprazole 20 mg TID for 7 days as an adjuvant to oral clarithromycin 500 mg TID or gentamicin 20 mg TID (each was given for the final 5 days of the 7-day treatment course). Eradication was defined as the absence of evidence of H pylori 4 or more weeks after cessation of therapy. Eleven patients with active peptic ulcer disease were treated with omeprazole/clarithromycin; the eradication rate was 64%. Six healthy H pylori-infected volunteers were treated with omeprazole/gentamicin; no eradication was achieved. Omeprazole appears to be a useful adjuvant to some therapies but the results cannot be predicted. Combination therapy with omeprazole and clarithromycin warrants further study.

AB We examine a salt marsh host-parasitoid system, consisting of the planthopper per Prokelisia marginata and its egg parasitoid Anagrus delicatus, for evidence of stabilizing parasitoid behavior. We first determine if there is sufficient parasitoid aggregation to potentially stabilize the Prokelisia-Anagrus interaction, using methods that infer parasitoid behavior from the spatial pattern of parasitism. We then test a basic assumption implicit in theory, that the degree of parasitoid aggregation is invariant with respect to changes in overall host and parasitoid density, and through time. Our results suggest that Anagrus behavior should, in theory, exert a consistent stabilizing effect on Prokelisia-Anagrus dynamics.
   Using field experiments, and direct sampling of the spatial distribution of parasitoids, we then try to determine if parasitoid aggregation is in fact responsible for the heterogeneous pattern of parasitism observed in the field. The results of these studies indicate that there is insufficient parasitoid aggregation to account for this heterogeneity. Instead, factors such as the degree of tidal inundation, or the age of host eggs, may cause host patches to differ in their vulnerability to parasitoid attack.

AB We characterized the structure of 25 old-growth hemlock-hardwood forests in northern Wisconsin and adjacent Michigan in order to examine our working hypotheses that differences in their structure are related to stand age (i.e., stage of development) and that changes in stand structure continue after old-growth status is achieved. Estimates of stand age, i.e., age of oldest tree cored, based on 10 cores taken from hemlocks of a range of diameters in each stand, ranged from 177 to 374. By investigating the patterns of live tree structure, coarse woody debris (CWD), tip-up mounds, and canopy gaps in relation to stand age, we were able to infer changes that occur during stand development.
   Along the gradient of old-growth stand development, some changes in structural features, including total volume of CWD, snag (standing dead tree) basal area, and total area and average size of canopy gaps were continuous, linear increases over time. In contrast, changes in live tree and snag density, density of large trees, volume of well-decayed hemlock logs, and diameter-age relationships occurred after a threshold stand age of 275-300 yr was reached. Area and density of tip-up mounds and density of large seedlings and saplings were not correlated with stand age.
   Old-growth hemlock-hardwood stands at the upper end of the age continuum (> 275-300 yr) have accumulated both gradual and threshold structural changes, acquiring most of the following characteristics: (1) a strong correlation between age and diameter of trees, (2) low densities of live trees distributed across all size classes, (3) trees >70 cm dbh (diameter at breast height), (4) dead wood >120-150 m(3)/ha, with logs >80 m(3)/ha, (5) hemlock logs present in all decay classes, and (6) canopy gaps occupying >10% of the stand, with the average gap size > 50 m(2), some gaps > 200 m(2), and no more than 30% of the gaps <10 m(2). The two oldest stands may be at or near equilibrium, where maximum volumes of CWD are maintained through a balance of tree growth and mortality, and wood decay; and oldest tree age approaches 400+ yr, the maximum longevity typical for hemlock.

TI EFFECTS OF FIRE SEVERITY ON NITRATE MOBILIZATION IN WATERSHEDS SUBJECT
   TO CHRONIC ATMOSPHERIC DEPOSITION
SO ENVIRONMENTAL SCIENCE & TECHNOLOGY
LA English
DT Article
ID SOUTHERN-CALIFORNIA; FERTILIZATION
AB Severe fires in chaparral watersheds subject to air pollution from metropolitan Los Angeles mobilized accumulated nitrogen and caused streamwater to be polluted with nitrate at concentrations exceeding the Federal Water Quality Standard. Streamwater NO3-concentrations were elevated during peak flows, the largest of which was a debris flow that transported NO3- at concentrations as high as 1.12 mequiv/L. Annual NO3- loss from severely burned watersheds, averaging 1.2 kequiv/ha,was 40 times greater than that from areas that remained unburned. Fires of moderate intensity produced a more subdued response in stream discharge and soil nitrification and less than one-seventh the NO3- loss observed after Severe burning. We infer that the combination of atmospheric deposition with severe wildfires provides a strong and recurrent source of nitrate that could contribute to existing groundwater pollution in parts of eastern Los Angeles County. Moderating the fire regime by prescribed burning could provide substantial mitigation.

AB The significance of hydrolysis as a dissipation mechanism for 3-chloro-p-toluidine hydrochloride was studied in aqueous solutions buffered at pH 5, 7, and 9. High-performance liquid chromatography with ultraviolet detection was used to assess the stability of the compound in the sample solutions at several intervals over 31 days. Experiments were conducted with polytetrafluoroethylene sample containers to circumvent adsorption of the free base (3-chloro-p-toluidine) on borosilicate glass. The results indicated that 3-chloro-p-toluidine hydrochloride does not significantly hydrolyze in pH 5, 7, or 9 buffer solutions at 25-degrees-C over 31 days.

TI NGUGI-WA-THIONGO AND THE SEARCH FOR A POPULIST LANDSCAPE AESTHETIC
SO ENVIRONMENTAL VALUES
LA English
DT Article
DE NGUGI-WA-THIONGO; LANDSCAPE AESTHETICS; DEVELOPMENT; KENYA
AB This essay examines how Ngugi wa Thiong'o, East Africa's most prominent writer, treats the landscape as a fundamental social phenomenon in two of his most important novels, A Grain of Wheat and Petals of Blood. Basing his ideas in an ecological theory of landscape aesthetics resembling one recently developed in America, Ngugi understands that ability to control and manipulate a landscape defines a society. Nostalgia for the landscape lost to colonialism and to the corrupting and alienating influences of international capitalism needs to be replaced by its progressive evaluation as it is reshaped by collective action for a new future. Alienation from, and loss of responsibility for. the land may be a major factor contributing to Africa's environmental problems. Ngugi's position casts doubt on professional land management's ultimate ability to influence the shape of the landscape in the face of the collective social will.

   CATABOLISM
AB Thermoanaerobacter thermohydrosulfuricus Rt8.B1 catabolized xylose by the pentose phosphate pathway, and xylose isomerase and xylulokinase were inducible. The uptake of xylose was by two low-affinity, inducible systems. Both systems were resistant to the protonophore, tetrachlorosalicylanilide, the F1F0-ATPase inhibitor, N,N-dicyclohexylcarboiimide, and the sodium/proton antiporter, monensin. The high capacity system (100 nmol min(-1) (mg protein)(-1)) was only expressed when the bacterium was grown with a high concentration of xylose (50 mM). It took more than 60 mM xylose to saturate the high capacity system. When T. thermohydrosulfuricus was grown with a low concentration of xylose (5 mM), xylose uptake was saturated by as little as 10 mM xylose (18 nmol min(-1) (mg protein)(-1)). Cells grown with 50 mM xylose could not transport glucose, and high capacity xylose transport was not inhibited by glucose or non-metabolizable glucose analogues. Cells grown with 5 mM xylose transported glucose at a rapid rate (30 nmol min(-1) (mg protein)(-1)), and low capacity xylose uptake was competitively inhibited by either glucose or 2-deoxy-glucose. Because the glucose uptake of cells grown on 5 mM xylose was competitively inhibited by xylose, it appeared that the low capacity xylose uptake system was a glucose/xylose carrier.

TI SUGARCANE IN MONOCULTURE OR IN ROTATION WITH SWEET CORN
SO FIELD CROPS RESEARCH
LA English
DT Article
DE CROPPING SYSTEM; ROTATION; SACCHARUM; SUGARCANE
AB Farmers in many regions of the world grow a horticultural or grain crop between sugarcane (a complex hybrid of Saccharum spp.) cycles. This additional crop often requires higher amounts of P or K fertilizers than does sugarcane. Some sugarcane growers in Florida precede 2- to 5-year cycles of sugarcane with one crop of spring-harvested sweet com (Zea mays L.). A disadvantage perceived with this rotation is that the higher amounts of P fertilizer applied to sweet com may reduce sugar yields of sugarcane. The primary objective of this study was to compare the sugarcane yields of a sugarcane and sweet com rotation with those of monocropped sugarcane. Phosphorus and K fertilizers were also added to sugarcane at different rates in each rotation to form four cropping practices. Responses of four sugarcane cultivars were also tested among these cropping practices. Sugarcane experiments were conducted at three diverse field locations. Each location was harvested twice, first in the plant crop and about 1 year later in the first-ratoon crop. At least one cropping practice including sweet com at each location had sugar yields (t sugar/ha) comparable to those of the highest monocropped sugarcane yields. Responses to cropping practices differed by location. Also, cultivars responded differently to cropping practices. By determining location-specific sugarcane fertilizers and cultivars, growers can grow sweet com and sugarcane in rotation without reducing sugar yields of sugarcane. More research to determine appropriate cultivars and fertilizer rates could probably improve yields of sugarcane subjected to the sugarcane-sweet corn rotation and its residual fertilizers.

TI DOUBLE CROPPING WHEAT AND CORN IN A SUBHUMID REGION OF CHINA
SO FIELD CROPS RESEARCH
LA English
DT Article
DE CROPPING SYSTEM; EVAPOTRANSPIRATION; SOIL WATER; SPATIAL DISTRIBUTION;
   WATER-USE EFFICIENCY
AB Double cropping wheat (Triticum aestivum L.) and com (Zea mays L.) is common in sub-humid regions of north China. This study was conducted to evaluate the system without irrigation. During the 5-year study period, annual rainfall averaged 638 mm with 387 mm occurring in July, August and September. Water stress often occurred from mid-April to the end of the wheat growing season in early June, and sometimes extended to the early part of the com season that begins immediately after wheat harvest and ends in mid-September. Wheat and com grain yields increased as a linear function of evapotranspiration. Average grain yield was 5.2 Mg ha-1 for wheat and 5.1 Mg ha-1 for com, with water-use efficiencies, expressed as grain yield per unit of water consumed, of 1.48 and 1.94 kg m-3, respectively. Average precipitation values for the 5-year study period closely parallelled long-term averages, and a probability analysis indicates that yields obtained in the study may be representative of what can be expected over a long period. Therefore, double cropping wheat and com in this region of China appears highly feasible and results in more than 95% of the precipitation being utilized by evapotranspiration during the growing seasons. Soil water content fluctuates periodically during the year. Phase lags and amplitude decrease with soil depth. One-half of the water utilized by wheat, 175 mm, was furnished by rainfall during the growing season, and the other half was obtained from soil water stored at the time of seeding in mid-October. In contrast, soil water increased during the com growing season in which rainfall was 384 mm, and evapotranspiration was 263 mm.

AB While Pharaoh ants, Monomorium pharaonis (L.), are generally considered indoor pests, we observed these ants foraging at 51.7% of outdoor monitoring sites located on exterior wall surfaces of apartment buildings in contrast to 11.6% of indoor sites. The number of ants per infested monitoring site did not vary significantly with counts averaging from 46 to 118. Commercial bait stations containing a delayed action toxicant placed solely on the exterior walls of buildings, or outdoors, provided a 94% reduction in Pharaoh ant numbers within 1 week in contrast to a 9% reduction in untreated buildings. This was similar to the reductions from buildings treated with bait stations placed both indoors and outdoors. While a total of 3 ants were found indoors in treated apartments, indoor counts from untreated buildings also were low. Initial outdoor ant counts were 2 to 20 times higher than indoor counts, and the significant population reductions were attributed to a reduction in counts from outdoor sites.

AB Three sugarcane (Saccharum spp.) fields in southern Florida were sampled to assess population densities of the sugarcane lace bug (Leptodictya tabida Herrich-Schaeffer) on leaves during 1990 - 1992. The study began several months after the bug was first discovered in Florida. A mean of 6.3 (SEM=0.51) bugs (all life stages) per leaf was observed over the entire study. Average densities per field per sample date ranged up to 74 bugs (all stages) per leaf. The bug was present from late spring through winter but exhibited a propensity for 2 annual peaks in density, one during late spring/early summer before summer rains and one during the fall after summer rains. Bug populations were very low from late March to May. A general decline in densities of the bug occurred during the study. No parasites, predators or pathogens of the bug were observed. In a laboratory trial, adults and nymphs survived 3-h exposures to 0 degrees and -5 degrees C, indicating short periods of cold weather may have little impact on population levels of the bug. Among 14 sugarcane varieties, 'CP73-1547' was relatively resistant to the bug while 'CP81-1254' was relatively susceptible based on bug densities per leaf.

AB Bacteria isolated from the Mexican fruit fly, Anastrepha ludens Loew, were identified and found to be similar to bacteria isolated from other fruit fly species. Bacteria of the same species as those identified from A. ludens were obtained from the American Type Culture Collection (ATCC). These bacteria were cultured and attractiveness to A. ludens adults was determined for the whole beer, and for filtered and autoclaved supernatants in laboratory bioassays. All bacterial cultures were attractive to A. ludens, and some were significantly more attractive than others. Autoclaved supernatants were significantly more attractive than the whole beer or filtered supernatants. Two strains of Bacillus thuringiensis (serovars finitimus and kurstaki), not previously reported to attract fruit flies, were attractive to A. ludens. In field studies, metabolites from bacterial fermentation of two cultures (ATCC #8090 and #13883) captured as many A. ludens adults as Torula yeast/borate pellets. Metabolites from these two cultures caught nearly twice as many females as males compared to about equal numbers of males and females captured by Torula yeast/borate pellets and Nulure(R). Consistent with laboratory bioassays, metabolites from RGM-1 caught significantly fewer A. ludens adults than the metabolites from #8090 and #13883.

AB The molecular motion of sucrose in water/alcohol/sucrose/casein solutions was studied by C-13-NMR spin-lattice relaxation measurements. The results suggest that the conformation of sucrose is unaffected by concentration, temperature, or the presence of alcohol or casein. There is no evidence for the interaction of sucrose with either alcohol or protein. Changes in the hydrodynamic radius of sucrose from relaxation measurement using solution or water viscosities were inconclusive.

AB The southern Appalachians experienced record precipitation deficits for 4 consecutive years in the mid-1980s. We analyzed the impacts of the drought on the hydrology and stemwood growth of a 33-year-old white pine plantation. Increment cores and dendrometer bands indicated a significant reduction in basal area growth during the drought for all tree classes (dominant, codominant, and intermediate) and shifts in patterns of seasonal growth. There was little variation in pine foliage litterfall over the drought period, but substantial variation in other litter-fall components (e.g. wood, cones, seeds, etc.). Precipitation-runoff (P-RO) relationships indicated less variation in evapotranspiration (ET) over the drought period than predicted by simulation modeling. The discrepancy between measured and modeled ET may be related to the importance of stored soil water to streamflow which dampens P-RO ET estimates. Regression analyses showed that growing season water potential explained as much as 61% of the variation in annual basal area growth. No significant relationships were established with climatic variables alone.

AB Mortality of red spruce (Picea rubens Sarg.) was assessed in an old-growth spruce-fir forest before and after adelgid-induced mortality of canopy fir at about 1985, Mortality rates of red spruce canopy trees remained low (less than 2% year-1) following the loss of fir from the canopy. However, the proportion of mortality attributable to wind increased from less than 60 to 90%. Transects placed in areas of concentrated wind damage revealed that uprooting or snapping accounted for 94% of the mortality of spruce canopy trees in the winter of 1987-1988. The transect data were biased toward wind-damaged areas and revealed the potential impact of wind-related mortality on spruce. There was no evidence of atypically high wind velocities in the general area, or of a decline in the radial growth of spruce trees prior to death. It was concluded that the loss of Fraser fir (Abies fraseri (Pursh) Poir.) from adelgid infestation has increased wind exposure to the remaining canopy trees. The increased exposure of southern Appalachian red spruce to wind must be considered in studies of its health.

AB A total diet composite based on foods from the U.S. FDA Total Diet Study was investigated to assess its suitability as a slurry material as a candidate reference material in the form of a slurry. Results for the distribution of chlorine and sodium (overall variation 2 % for Na and 3 % for Cl) indicated no serious problems of sedimentation. Similarly determination of Co, Se, Rb, Sn, Fe and Zn covering an overall concentration (dry weight basis) range of 25 ng/g for Co to 33 mug/g for Fe and Zn, suggests that the homogeneity of the composite is reasonably good. However the operational steps adopted for this preliminary investigation were not optimal. Use of a high pressure diffusion type of approach adopted by the National Research Council of Canada in preparing the lobster hepatopancreas matrix (LUTS-1) should further improve the homogeneity characteristics of the slurry.

AB T (Texas) cytoplasm is associated with a mitochondrial disruption that is phenotypically expressed during microsporogenesis resulting in male sterility. Restoration of pollen fertility in T-cytoplasm maize is controlled by dominant alleles at two unlinked, complementary, nuclear-encoded genes, rf1 and rf2. As a first step in the molecular isolation of the rf2 gene, 178,300 gametes derived from plants that carried the Mutator, Cy or Spm transposon families were screened for rf2 mutant alleles (rf2-m) via their inability to restore pollen fertility to T-cytoplasm male-sterile maize. Seven heritable rf2-m alleles were recovered from these transposon populations. Pedigrees and restriction fragment length polymorphism (RFLP)-based analyses indicated that all seven rf2-m alleles were derived independently. The ability to obtain rf2-m derivatives from Rf2 suggests that Rf2 alleles produce a functional product necessary to restore pollen fertility to cmsT. Molecular markers flanking the rf1 and rf2 loci were used to decipher segregation patterns in progenies segregating for the rf2-m alleles. These analyses provided preliminary evidence of weak, third restorer gene of cmsT that can substitute for Rf1.

AB The aqueous solubility of synthetic imogolite at 298 K and 1 bar pressure and at 373, 393, 408, and 423 K and equilibrium vapor pressure was determined in 0.01 M NaCl at two initial pH levels. Samples were run with and without pretreatment with HCl and in the presence and absence of gibbsite or boehmite. At 298 K and 1 bar pressure, dissolution of non-HCl-washed synthetic imogolite at the initial pH values of 1.8 and 2.2, with or without addition of AlCl3 and H4SiO4, approached equilibrium within 335 and 33 days, respectively. Dissolution of HCl-washed imogolite and gibbsite at initial pH 2.5 and 3.0 reached equilibrium within 332 and 487 days, respectively. There was no difference between the log IAP values at equilibrium from non-HCl-washed and HCl-washed imogolite samples. Dissolution of non-HCl-washed synthetic imogolite and gibbsite at an initial pH 2.2 attained equilibrium within 485 days of equilibration, but equilibrium was not reached after 861 days for samples at an initial pH 1.8. Dissolution of HCl-washed imogolite at initial pH values of 2.5 and 3.0 did not reach equilibrium within 766 days. At 373 and 393 K and an initial pH 3.0, dissolution of imogolite and synthetic boehmite reached equilibrium. The calculated Gibbs free energies of formation at 298 K were 2923.79 +/- 3.38 (synthetic imogolite), -2920.83 +/- 3.92 (natural imogolite), -1155.06 +/- 1.43 (gibbsite), -915.10 +/- 1.83 (boehmite, extrapolated from elevated temperature), and -920.64 +/- 1.41 kJ mol-1 (boehmite, from 298 K solubility). The results indicate that synthetic imogolite is more soluble than earlier reports suggest and natural imogolite is less stable than its synthetic counterpart.

Grasslands Matua were compared with a similarly managed endophyte-free tall fescue x perennial ryegrass hybrid (Festuca arundinacea Schreb. x Lolium perenne L.) cv. Johnstone. A field study was conducted on the Appalachian Plateau of southern West Virginia, USA (81-degrees-W, longitude; 38-degrees-N, latitude; 850m above sea level) for three consecutive years. Nitrogen totalling 0, 168, and 336 kg N ha-1 year-1 was applied to stands managed as hay. Annual herbage yields were similar for both species in year 1 (1989), but by year 3 (1991) Matua sown-grass yield was about 35% of first-year yields. Total herbage yield for Matua plots in the third year was similar to first-year yields owing to encroachment by non-seeded grasses and white clover (Trifolium repens L.). Matua was susceptible to powdery mildew [Blumeria graminis (DC) E. O. Speer] in this environment, and was similar in productivity (first year only) and nutritive quality to tall fescue x perennial ryegrass hybrid. Matua use may be limited to areas where low-temperature stress and resultant winter damage is unlikely to occur.

A p-turn conformation was identified from the NOE connectivities observed for the peptide in a mixed solvent of water and DMSO, indicating that this is the biologically active conformation of the peptide. This study also suggests that the use of such an aqueous-like solvent mixture allows the observation of a preferred conformation for small linear peptides in the presence of conformational averaging.

AB Proteins are the major source of peanut flavor precursors such as peptides and amino acids. Changes in the protein structure possibly would lead to a change in peanut flavor quality. As peanut maturity can affect peanut flavor quality, it was postulated that proteins between mature and immature peanuts could be structurally different. To support this postulation, peptide mapping of mature and immature peanut proteins was carried out. Peptide maps were produced by digesting peanut proteins with an arginyl endopeptidase. This was followed by treatment of the resultant protein digests with trichloroacetic acid (TCA) or an affinity column of immobilized anhydrotrypsin (IMAT). The TCA-soluble peptide fractions were then subjected to analyses by C18 reversed-phase high-performance liquid chromatography (HPLC), whereas fractions, which contained carboxyl- or C-terminal and non-C-terminal peptides, from the IMAT column were analyzed by capillary zone electrophoresis (CZE). For resolution purposes, fractions collected from the C18 column of HPLC were further analyzed by CZE. Results showed that peptide maps from immature peanut proteins contained peptides different from those from mature peanut proteins. Peptides such as peptide I (a C-terminal peptide) from immature peanut proteins and peptide M (a TCA-soluble peptide) from mature peanut proteins were identified. This difference in peptide patterns indicates that proteins between mature and immature peanuts were structurally different.

AB Exposure of commercial White Rose potatoes to fluorescent light for 20 days induced a time-dependent greening of potato surfaces; an increase in chlorophyll, chlorogenic acid, and glycoalkaloid content (alpha-chaconine and alpha-solanine); and no changes in the content of inhibitors of the digestive enzymes trypsin, chymotrypsin, and carboxypeptidase A. The maximum chlorophyll level of the light-stored potatoes was 0.5 mg/100 g of fresh potato weight. Unstored potatoes contained no chlorophyll. Storing potatoes in the dark did not result in greening or chlorophyll formation. Chlorogenic acid and glycoalkaloid levels of dark-stored potatoes did increase but less than in the light-stored potatoes. In the light, chlorogenic acid concentration increased from 7.1 mg/100 g of fresh potato weight to a maximum of 15.8 mg after greening. The corresponding values for alpha-chaconine are 0.66 and 2.03 mg and for alpha-solanine 0.58 and 1.71, respectively, or an approximately 300% increase for each glycoalkaloid. The trypsin, chymotrypsin, and carboxypeptidase A concentrations, respectively, of about 1000, 375, and 100 units/g of dehydrated potato powder were not changed. Experiments on delay of greening by immersion in water suggest that (a) chlorophyll formation and glycoalkaloid synthesis are unrelated physiological processes and (b) the concentration of chlorophyll is 26 times greater, of chlorogenic acid and glycoalkaloids 7-8 times greater, and of protease inhibitors about 2-3 times lower in the peel of the green potatoes than in the whole tuber. The described compositional changes should help define consequences of potato greening for plant physiology, food quality, and food safety.

AB Marsh grapefruit (Citrus paradisi Macf.) fruit epicuticular wax was fractionated into various lipid classes by thin-layer chromatography and quantified by gas chromatography, and structures were verified by mass spectroscopy and H-1 and C-13 magnetic resonance spectroscopy. Friedelin was shown for the first time to be the major component of grapefruit epicuticular wax. Other triterpenes were also present in lesser quantities. Triterpene structures verified were beta-amyrin, beta-amyrone, beta-amyrin acetate, alpha-amyrin, alpha-amyrone, alpha-amyrin acetate, and 24-methylenecycloartanol. Further analyses revealed friedelin levels to be 5-45% of the wax in 8 of 14 other fruits and vegetables and from 9% to 18% in the leaves of 3 citrus cultivars.

AB Corn distillers' dried grains (DDG), corn distillers' dried solubles (DDS), and corn distillers' dried grains with solubles (DDGS) are coproducts from ethanol production. Knowledge of the carbohydrate composition of these coproducts will increase their potential for further processing. Materials were first hydrolyzed by trifluoroacetic acid, and the resulting neutral sugars were analyzed by high-performance liquid chromatography. Glycerol (3.5-10.2%), arabinose (2.8-10.0%), xylose (3.2-14.1%), mannose (0-2.6%), glucose (5.6-18.8%), and galactose (1.1-2.6%) were found in these ethanol coproducts. Corn DDS had the highest content of neutral sugars (39%), of which glucose accounted for about half of this total. Neutral carbohydrates from the hydrolysis of the 80% methanol soluble fraction (monosaccharide and low molecular weight oligosaccharides) from these corn distillers' products were mostly glycerol and glucose.

TI TRIAL OF NEAR-INFRARED REFLECTANCE SPECTROSCOPY IN A HUMAN FIBER
   DIGESTIBILITY STUDY
SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY
LA English
DT Article
ID FAT
AB A trial of near-infrared reflectance spectroscopy (near-IRS) to predict fecal concentration of dietary fiber (DF) in humans was performed. Fecal samples from 34 persons consuming 6 diets of known DF content were scanned by near-IRS. Diets consisted of a liquid nutrition supplement and quick breads containing either 0 g of fiber, 10 g of wheat bran, 30 g of wheat bran, 10 g of vegetable fiber mix, 30 g of vegetable fiber mix, or 30 g of sugar beet fiber. Neutral detergent fiber (NDF) determinations were made on all fecal samples. An equation to predict NDF concentration was derived from 109 fecal samples using modified partial least-squares analysis. Neutral detergent fiber concentrations predicted from near-IRS data were compared to observed NDF concentrations of 75 other samples to validate the equation. Comparison of observed vs predicted NDF revealed nearly perfect correlation between the two. Calibration and validation of a near-IRS equation generally requires that tradiational chemical analysis be done on only two subsets of samples, thereby reducing the time and effort needed to analyze DF concentrations. This study demonstrates that near-IRS is a viable tool for studying DF digestibility in vivo in humans.

AB A significant environmental degradation product of chloro-s-triazine herbicides is chlorodiamino-s-triazine. Current chromatographic analytical methods are limited by the water solubility and inefficient recovery of this analyte. A diamino-s-triazine hapten was synthesized for the production of polyclonal antibodies. Other haptens were synthesized which differed in bridging group and ring substitution for use in immunoassay development using both indirect and haptenated enzyme formats. In general, antibody recognition of substituted s-triazines decreased as a function of amino side chain substitution. The assays were sensitive in the low micromolar range. Two assays were optimized and validated by comparison with a HPLC method for the analysis of chlorodiamino-s-triazine in treated pesticide waste samples. The correlation coefficients found were 0.988 and 0.979. It is anticipated that this immunoassay will provide a useful monitoring technique for on-site sampling and remediation of pesticide-contaminated areas.

SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY
LA English
DT Article
ID DITERPENE RESIN ACIDS; RANGE CATTLE; OLEORESIN
AB A crude acid fraction isolated from the needles of ponderosa pine (Pinus ponderosa Laws) induced abortions when fed to late-term pregnant beef cows. The major components identified in this abortifacient fraction were four long-chain fatty acids (palmitic, linoleic, oleic, and stearic acids), four abietane diterpene acids (isopimaric, dehydroabietic, abietic, and neoabietic acids), and two labdane diterpene acids (imbricataloic and isocupressic acids). From this crude acid fraction isocupressic acid was isolated and dosed by gavage to five pregnant cows starting on day 250 of pregnancy. Four of the five cows aborted calves when administered isocupressic acid at dosages between 99 and 152 mg/kg (twice daily). At a lower dosage of 66 mg/kg no abortion occurred. No abortifacient activity was observed after a mixture of the abietane diterpene acids was gavaged at dosages of 77 and 120 mg/kg (twice daily); but at higher dosages (238 and 255 mg/kg) these compounds were toxic, and two cows died. It was concluded that the primary abortifacient constituent in ponderosa pine is isocupressic acid and that a separate toxic syndrome may occur from ingestion of high levels of some abietane diterpene acids in pine needles.

ID IDENTIFICATION; POPCORN; AROMA
AB The volatiles of some canned, frozen, and fresh sweet corn products were analyzed by capillary GLC-MS. Important aroma compounds identified include 2-acetyl-1-pyrroline and 2-acetyl-2-thiazoline. Major volatiles found in all three corn products include dimethyl sulfide, 1-hydroxy-2-propanone, 2-hydroxy-3-butanone, and 2,3-butanediol. Pyridine, pyrazine, alkylpyrazines, and 2-acetylthiazole were additional major components in the canned products but minor components in the fresh and frozen products. Comparison of calculated odor units indicated that the compounds most important to canned sweet corn aroma include dimethyl sulfide, 2-acetyl-1-pyrroline, 2-ethyl-3,6-dimethylpyrazine, acetaldehyde, 3-methylbutanal, 4-vinylguaiacol, and 2-acetylthiazole. The alkylpyrazine and 3-methyl-butanal are less important to fresh sweet corn aroma, where 2-acetyl-2-thiazoline also seems to be important.

ID FUSARIUM-WILT
AB As part of an effort to identify lines or cultivars of cotton Gossypium spp. with resistance to the root-knot nematode Meloidogyne incognita (Kofoid and White) Chitwood (RKN), seeds were analyzed for gossypol and other terpenoid aldehydes (TA's), rather than roots where the RKN lives. If a correlation between plant resistance to RKN and TA's could be demonstrated, the time and costs associated with propagating seedlings could be avoided. Some spectrophotometric and high-pressure liquid chromatography procedures were evaluated. Total terpenoid aldehydes obtained by the aniline analysis were higher than those obtained with the HPLC methods. Gossypol was virtually the only terpenoid aldehyde found in cottonseed, but small amounts of hemigossypolone were also found to be present. No statistically significant correlation was found between seed gossypol concentrations and plant resistance to RKN.

Splenocytes from mice immunized with a hygromycin B-ovalbumin conjugate were fused with SP2/0 myeloma cells, and hybridomas secreting antibodies against hygromycin B were selected and cloned. An assay using the antibody with the highest affinity for hygromycin B is described. The monoclonal antibody is specific for hygromycin B and does not cross-react with structurally similar aminoglycoside antibiotics commonly added to medicated feed. When tissue samples were spiked with hygromycin B, the average percent recoveries at 1, 2, and 4 ppm were 83, 82, and 91%, respectively. The ELISA described here can be used to rapidly screen porcine kidney samples for the presence of hygromycin B residues.

AB A series of 300 and 500 W xenon arc lamps, normally operated at 20 and 35 A, respectively, have been pulsed as high as 300 A to achieve higher intensities in combination with a linear photodiode array detector. Initial tests without pulsing showed that the 500 W lamps are generally more intense, but the 300 W lamps were more intense at 200 nm. With 300 A pulses, both lamps showed a factor of 500 increase in the pulse intensity over the simmer intensity. With a 0.5 ms pulse and a 3.75% duty cycle, pulsing at 300 A provided a factor of 18 increase in the integrated intensity over normal d.c. operation. The increase in integrated intensity can result in a comparable improvement in detection limits since the instrument is detector noise limited. Both the 300 and 500 W lamps exhibited failure after the equivalent of 200 atomizations at 200 A. With 100 A pulses, the 300 W lamp was still operating after the equivalent of 800 atomizations. At both pulse levels, the decrease in intensity with time was accelerated as compared with d.c. operation. It was concluded that an improved lamp design is necessary to make pulsed operation economically attractive.

AB Calpastatin is a specific inhibitor of the calpains. Calpains play a key role in postmortem tenderization of meat and have been hypothesized to be involved in muscle protein degradation in living tissue. Isolation, cloning of complementary DNA, and nucleotide sequencing of bovine calpastatin from the longissimus muscle have been completed. Two clones were identified that encompass the entire coding sequence. Clone pCR41, derived by reverse transcription-PCR, covers domains L and 1; clone pBSA1, obtained from cDNA library screening, covers domains 2 through 4 in addition to the 3'-nontranslated region. Nucleotide sequence analysis of the cDNA for bovine calpastatin revealed an average nucleotide sequence identity of approximately 70 to 80% compared with published calpastatin nucleotide sequences of human, rabbit, and pig. Exon 3, corresponding to a highly conserved 22-amino acid region, was deleted from bovine calpastatin domain L. The calculated molecular weight of bovine skeletal muscle calpastatin of 706 amino acid residues (M(r) 75,842) corresponds-to the value of purified bovine skeletal muscle calpastatin as determined by SDS-PAGE (M(r) 68,000). Northern blot analysis revealed the presence of multiple calpastatin mRNA transcripts having estimated sizes of 3.8, 3.0, and 1.5 kb in beef and 3.8, 3.0, 2.5, and 1.5 kb in sheep. Calpastatin mRNA expression was increased with beta-adrenergic agonist-induced muscle hypertrophy.

AB Sixty crossbred barrows (average 30 kg) were used in a 5 x 2 factorial treatment array to examine interactions between dietary protein concentration (11, 15, 19, 23, or 27% CP) and recombinant porcine somatotropin (rpST: 0, excipient buffer vs 100 mu g.kg(-1).d(-1)) for 42 d on muscle fiber morphology and meat tenderness. Diets were isocaloric (3.8 Mcal of DE/kg) and of equal lysine (4.9 g/Mcal of DE) achieved by diluting soybean meal with cornstarch and by addition of crystalline lysine. Dosage of rpST and feed intake (80% of predicted ad libitum) were adjusted weekly. Four muscles (longissimus = LM; semimembranosus = SM; semitendinosus = ST; triceps brachii = TB) were evaluated. Percentages of muscle fiber types (beta R, alpha R, alpha W) for the LM, SM, and TB were not influenced by rpST treatment. More alpha R and fewer alpha W fibers were found in the ST muscle of rpST-treated pigs. No interactions were observed between rpST treatment and dietary protein for muscle fiber type distribution. Dietary protein had no consistent influence on the distribution of muscle fiber types in all four muscles. Area of fibers generally increased in rpST-treated pigs compared with controls when diets contained 19% or more CP. The LM shear force was increased (13%) by rpST treatment for chops frozen after 5 d of storage in the cooler, but not in those chops frozen within 1.5 h postmortem. Dietary protein had a variable influence on tenderness. These data indicate that muscle fiber growth (hypertrophy) in pigs is positively influenced by rpST treatment. Marginal dietary protein intake reduces muscle fiber growth responses to rpST.

AB Lactating dairy goats were exposed to aflatoxin (100 and 200 ppb) and hydrated sodium calcium aluminosilicate at 1, 2, and 4% in two separate experiments. Naturally occurring low levels of aflatoxin M(1) (.009 ppb) were found in the milk of the control diet, whereas there were no detectable levels of aflatoxin MI in the milk of diets containing hydrated sodium calcium aluminosilicate in both experiments. In Exp. 1, no treatment-related differences in clinical behavior or significant difference in the feed intake, milk production, or milk component analyses were observed with 200 ppb of aflatoxin and 4% hydrated sodium calcium aluminosilicate. However, 4% hydrated sodium calcium aluminosilicate was responsible for an 86.9% reduction of aflatoxin M(1) residue in the milk of dairy goats. In Exp. 2, the combination of 1% hydrated sodium calcium aluminosilicate and aflatoxin at 100 ppb resulted in an overall reduction of aflatoxin M(1) residue by 51.9%, which represented a mean change of aflatoxin M(1) from .553 to .266 ppb of aflatoxin M(1) in the milk. The diet that contained 2% hydrated sodium calcium aluminosilicate and 100 ppb of aflatoxin further reduced aflatoxin residue by a mean change from .553 to .098 of ppb aflatoxin M(1), which represents an 82.2% reduction of aflatoxin M(1) residue in the milk. Analysis of the data by time indicated that there were no statistical differences between days of sampling. Information regarding the ability of hydrated sodium calcium aluminosilicate to prevent or reduce the level of aflatoxin M(1) residues in milk is critically needed. This finding has important implications, because milk is ultimately consumed by humans and animals, and the reduction of aflatoxin contamination in the milk could have an important impact on their health.

AB Disposition of oral neomycin in calves was determined using C-14-labeled neomycin. The influences of age, diet, and method of administration were observed. All calves were killed 96 h after a single oral dose of [C-14]neomycin (approximately 30 mg/kg) and the distribution of C-14 in excreta and tissues was determined. As indicated by urinary excretion, absorption of neomycin was greater in 3-d-old calves (11.1 +/- 1.8% of the dose) than in 54- to 64-d-old nonruminating calves (1.5 +/- .58% of the dose) dosed similarly. Absorption of neomycin was similar in nonruminating (1.5 +/- .58%) and ruminating (2.13 +/- .62%) calves when the doses were administered in solution via a nippled bottle. In ruminating calves, absorption was somewhat less when the dose was administered on feed via a gelatin capsule (.5 +/- .06% of the dose) than when given in solution via a nippled bottle (2.13 +/- .62% of the dose). In calves dosed at 3 d of age, C-14 concentration in the kidneys represented 55 +/- 4.9 ppm of neomycin equivalents. The next highest concentration occurred in the livers, which contained less than 5% of the level in kidneys. Tissue concentrations of C-14 were related to absorption (as indicated by urinary excretion). Isolation and characterization: (positive-ion fast atom bombardment mass spectroscopy and nuclear magnetic resonance spectroscopy) of C-14 compounds,in kidneys of calves dosed at 3 d of age indicated that at least 90% of the C-14 was present as neomycin. Neomycin was also the major C-14 compound in feces of all calves (70 to 80% of the C-14 present); Results suggest that use of neomycin in veal production at recommended levels would cause kidney residues of neomycin above the .250 ppm tolerance currently observed in the United States.

AB In a 2 x 2 factorial experiment, 110 Holstein cows (55 first-breeding and 55 repeat-breeding), free of genital abnormalities, were injected i.m. at the time of insemination with either saline solution or 100 mu g of GnRH. Blood samples were drawn from the tail vein or artery of 22 cows (10 first- and 12 repeat-breeding) immediately before GnRH injection and again 1 and 2 h later to determine whether the GnRH induced the release of LH. The GnRH caused LH release in 18 of 22 cows, with a greater (P < .05) mean concentration of LH than that in saline-treated cows at 1 h (2.3 vs 7.0 ng/mL) and 2 h (2.5 vs 6.0 ng/mL) after injection. Length of estrus and time of ovulation were calculated from estrus checks and ovarian palpations per rectum at 8-h intervals. The GnRH injections produced no change in duration of estrus (19.2 h) or time of ovulation postestrus (9.5 h). The cows were slaughtered 41 to 90 (($) over bar x = 60) h after ovulation to determine the ovum cleavage rate and the number of accessory sperm in the zona pellucida. The GnRH treatment increased the incidence of twin ovulations but did not increase the number of accessory sperm or improve the proportion of ova that cleaved in either first-service or repeat-breeding cows.

AB We investigated the effects of supplementing Rambouillet x Suffolk wether lambs grazing irrigated 'Cimarron' alfalfa (Medicago sativa L.) with three levels (0 [C-0], 123 [C-123], and 247 [C-247] g of DM.lamb(-1).d(-1)) of cracked corn. Each treatment group also received 190 g of a supplement designed to prevent bloat. Replicated pastures (three per treatment) grown on a fine, mixed, thermic Torretic Paleustoll soil were grazed rotationally (forage plus supplement allowance of 6.5% of BW/d) by lambs for 85 d during spring 1992. Supplemental corn levels were analyzed as single degree of freedom contrasts for linear and quadratic effects. At the start of the experiment, lambs weighed 30.7 +/- .32 kg. Average daily gains for Co C-123, and C-247 were 141, 154, and 169 g/d, respectively. Lamb production per hectare increased quadratically (P<.01) with increasing corn level (C-0 [716 kg of lamb/ha], C-123 [816 kg of lamb/ ha], and C-247 [964 kg of lamb/ha]). Supplementation with C-247 vs C-0 increased carcass weights (11%), dressing percentage (6%), and backfat thickness (30%). Plasma urea N (PUN) concentrations did not differ (P>.10) between Co and C-123 after 27 d of corn supplementation, but after 75 d PUN concentrations between C-0 and C-123 had decreased(P<.10) by 11%. For C-247, PUN concentrations after 27 and 75 d of corn supplementation had decreased(P<.10) by 17 and 18%, respectively, compared with C-0. Plasma urea N concentrations increased (P<.01) linearly (r(2) = .93) with an increase in digestible CP:DE ratio (DP: DE). Lambs with the greatest growth response had the lowest PUN and DP:DE levels. Feeding limited amounts of corn to lambs grazing alfalfa increased lamb production per hectare and per lamb, seemingly through more efficient use of the alfalfa protein.

DT Article
ID PYRAZINES
AB The 2-methoxy-3-alkylpyrazines in 6 types of carrot products were determined by a stripping-selective trapping procedure followed by purge-and-trap gas chromatographic analysis with an NP detector. The aroma threshold of one of the principal pyrazines, 2-methoxy-3-sec-butylpyrazine, in a carrot medium was 0.19 ng/g. The concentrations of this compound in whole-carrot products were 0.43 (fresh), 0.291 (canned, cooked), and 0.224 ng/g (frozen). A diced, cooked, and freeze-dried product contained 0.070 ng/g. All of these products contained only this pyrazine. In contrast, a shredded, bagged product contained 2-methoxy-3-isopropylpyrazine as the sole pyrazine (0.32 ng/g), and a sliced, dried product contained a mixture of 3 pyrazines: 2-methoxy-sec-butyl- (0.109 ng/g), 2-methoxy-3-isopropyl- (0.176 ng/g), and 2-methoxy-3-isobutylpyrazine (0.029 ng/g). The pyrazine concentrations in most of these products (except the freeze-dried product) exceeded the threshold value.

AB Fumonisin B-1 (FB1) labeled on the branch methyl groups with deuterium was produced in liquid cultures, and methyl-D-3-labeled methionine was added. The isolated FB1 had 90% incorporation of 6 deuterium atoms and 9% incorporation of 3 deuterium atoms. The labeled FB1 was used as an internal standard for 2 analytical methods to measure FB1 in extracts of corn, corn products, and cultures. One method was hydrolysis followed by gas chromatography/mass spectrometry (GC/MS) of the derivatized backbone, and the other was analysis by fast atom bombardment MS (FAB/MS). Incorporation of labeled FB1 into samples resulted in a GC/MS method with improved precision and accuracy and allowed for a quantitative FAB/MS method.

AB Because the chemical structure of fumonisin BI (FB1) has several structural features in common with the sphingoid bases, sphingosine and dihydrosphingosine (sphinganine), we tested the hypothesis that the fumonisins might alter the normal cellular activity or the metabolism of endogenous free sphingoid bases. FB1 was found to be a potent inhibitor of de novo sphingolipid biosynthesis in vitro, its primary target being sphinganine N-acyltransferase. This inhibition resulted in a decrease in the biosynthesis of sphingosine and an accumulation of free sphinganine, an intermediate in the de novo biosynthetic pathway for complex sphingolipids. These findings led to the hypothesis that consumption of feed containing fumonisins should cause an increase in the ratio of free sphinganine to free sphingosine in tissues and serum. Data consistent with this hypothesis have been obtained from horses and pigs that consumed feed containing fumonisin-contaminated corn screenings and from rats fed feed supplemented with fumonisin-containing fungal culture materials or pure FB1. Thus, the ratio of free sphinganine to free sphingosine shows promise as a tissue, urine, or serum marker for animals consuming feed containing fumonisins. The present paper provides a detailed description of the extraction of free sphingoid bases and the liquid chromatographic method we used for determining the relative amounts of free sphingosine and free sphinganine in serum, urine, and various tissues of animals. Study results are summarized, and the ratio of free sphinganine to free sphingosine is discussed as a presumptive test for identifying animals consuming fumonisin-contaminated feed.

AB Urban temperature bias, defined to be the difference between a shelter temperature reading of unknown but suspected urban influence and some appropriate rural reference temperature, is estimated through the use of polar-orbiting satellite data. Predicted rural temperatures, based on a method developed using sounding data, are shown to be of reasonable accuracy in many cases for urban bias assessments using minimum temperature data from selected urban regions in the United States in July 1989. Assessments of predicted urban bias were based on comparisons with observed bias, as well as independent measures of urban heat island influence, such as population statistics and urban-rural differences in a vegetation index. This technique provides a means of determining urban bias in regions where few if any rural reference stations are available, or where inhomogeneities exist in land surface characteristics or rural station locations.

AB Peptostreptococcus anaerobius converted glutamine stoichiometrically to ammonia and pyroglutamic acid, and the Eadie-Hofstee plot of glutamine transport was biphasic. High-affinity, sodium-dependent glutamine transport (affinity constant [K-t] of 1.5 mu M) could be driven by the chemical gradient of sodium, and more than 20 mM sodium was required for half-maximal velocity. High-affinity glutamine transport was not stimulated or inhibited by a membrane potential (Delta Psi). Low-affinity glutamine transport had a rate which was directly proportional to the external glutamine concentration, required less than 100 mu M sodium, and was inhibited strongly by a Delta Psi. Cells which were treated with N,N-dicyclohexytcarbodiimide to inhibit the F1F0 ATPase still generated a Delta Psi but did so only if the external glutamine concentration was greater than 15 mM. Low-affinity glutamine uptake could not be saturated by as much as 200 mM glutamine, but glutamine(-1) accounts for only a small fraction of the total glutamine at physiological pH values (pH 6 to 7). On the basis of these results, it appeared that the low-affinity glutamine transport was an electrogenic mechanism which was converting a chemical gradient of glutamine(-1) into a Delta Psi. Other mechanisms of Delta Psi generation (electrogenic glutamine-pyroglutamate or -ammonium exchange) could not be demonstrated.

AB In field experiments traps were baited with live females or with a two-, four-, or eight-component blend of the 16-carbon aldehydes previously identified as components of the sex pheromone emitted by female Manduca sexta moths. The blends were formulated on rubber septa. Traps baited with a blend of all eight aldehydes captured more M. sexta males than any other treatment. Septa loaded with 600 mu g of the eight-component blend were attractive to males for about seven days in the field. Septa loaded with the eight-component blend and stored in a refrigerator at 4 degrees C for a year released the conjugated diene and triene aldehydes at the same rate as freshly prepared septa and were equally attractive in the field.

DT Article
ID HORSESICKNESS VIRUS; ELISA; IDENTIFICATION; GENOME
AB Reverse transcription-PCR (RT-PCR) was used to detect African horse sickness virus (AHSV), A single primer pair which amplified a 423-bp fragment of the S8 gene which encodes the NS2 protein of AHSV was identified. Amplification of this fragment from all nine serotypes of AHSV was achieved with these primers. Between 10(1) and 10(2) copies of AHSV genomic double-stranded RNA could be detected by RT-PCR followed by agarose gel electrophoresis and ethidium bromide staining. Application of RT-PCR to blood samples from AHSV-infected horses resulted in earlier detection of viremia than virus isolation did. Furthermore, viremia was detected by RT-PCR in blood samples from horses infected with an avirulent isolate of AHSV which were negative by virus isolation. AHSV was also detected by RT-PCR in spleen and lung samples from horses which died of AHSV infection. These results indicate that RT-PCR is a rapid and sensitive method for the identification of horses infected vith AHSV.

AB Nuclear magnetic resonance spectroscopy is a noninvasive technique that has found application in a variety of research areas. Nuclear magnetic resonance has been primarily applied to solution studies, but many dairy food ingredients or products are solids. In this paper, cross-polarization magic angle spinning nuclear magnetic resonance is applied to the study of freeze-dried cheese. The C-13 spectrum is dominated by the solid-like protein fraction. Liquid-like fat resonances can be detected by conventional one pulse experiments. The P-31 cross-polarization magic angle spinning nuclear magnetic resonance can specifically monitor phosphorus-containing ingredients in the solid state. Possible applications of solid-state nuclear magnetic resonance to dairy research are discussed.

AB Holstein bulls were assigned to sampling categories (AI stud, AI nonstud, or non-AI) based on bull code, controller number, and age at semen distribution. The AI stud bulls were sampled through traditional progeny-testing programs of 13 AI organizations; AI nonstud bulls had AI semen collection reported by another organization or by multiple organizations. The non-AI bulls had no reported AI semen collection. Actual daughter yield deviations for these three groups of bulls were compared with expected performance (parent average) to provide an indication of whether evaluations were free from bias for daughter yield deviations. Mean difference of daughter yield deviation from parent average was close to 0 kg for animal model evaluations of all 22,930 bulls but was positively biased by 46 kg of milk for AI nonstud bulls. Mean PTA and reliabilities for parents were highest for AI stud bulls and lowest for non-AI bulls. The AI stud bulls varied least and were intermediate for mean management, approximated as mean daughter yield minus bull PTA. Management was highest for AI nonstud bulls, which suggested that adjustment for heterogeneous variance might reduce bias. However, the effect of this adjustment on mean difference of daughter yield deviation from parent average was small.

AB Field exposures of 9950 containerized 12-wk-old loblolly pine (Pinus taeda L.) seedlings representing 53 commercially important, open-pollinated families were conducted to evaluate individual and interactive effects of acid rain and O-3 on growth response. A 36-plot field research facility comprised of 33 open-top chambers and three open plots was used to test effects of five O-3 levels that included ambient (A) and seasonally integrated levels that were 0.53, 1.10 1.58, or 2.15 times ambient. Individual effects of three levels of simulated acid rain (pH 3.3, 4.5, and 5.2) as well as their interaction with O-3 at 0.53A, 1.58A, and 2.15A levels were also included. Exposure to ambient air reduced average growth in height (26%), diameter (5%), and volume (14%) compared with growth of seedlings exposed to a 47% lower dose in charcoal filtered (CF) air. Responses to increasing O-3 above ambient levels varied widely between families, became increasingly inhibitory at the highest O-3 levels, but did not significantly exceed growth reductions found in ambient air. Diameter growth was reduced in most families by all levels of O-3 addition. Acid rain caused a general stimulation of height growth at ambient levels (pH 4.5), while both height and diameter growth were reduced at a mean pH of 3.3. Significant antagonism between rainfall acidity and O-3 effects on height and biomass increment was detected with increasing pollutant concentrations. Ozone reduced root/shoot biomass in most families, while acid rain did not.

ID FIELD EXPERIMENTS; SULFUR-DIOXIDE; OZONE; QUALITY; PLANTS; DESIGN
AB Tree seedling exposure studies, covering a wide range of experimental conditions in pollutant treatments, species, facilities, and exposure regimes, have been conducted during the past several years to determine acute effects and relative sensitivity of tree species in response to simulated acid precipitation and gaseous pollutants. Because of the difficulties inherent in conducting controlled exposures with mature trees (e.g., size, variability among experimental units, and costs associated with replication of treatments), seedling exposure studies have been initiated as the quickest way to address these issues. However, sufficient consideration has not been given to either the comparability of seedling studies or to their appropriate inference. The statistical power of any given analysis is rarely discussed when the outcomes are published. Appropriate and documented statistics of experimenter bias are often not reported, and variability in the exposure regime (i.e., treatment target levels) and the measurement of experimental variables is assumed to be zero, rather than quantified. Finally, the populations of seedlings for which seedling experiments have inference, the extent to which seedling responses are applicable to mature trees and forest condition, and the limitations in national or regional generalizations are crucial issues often left to an individual reader's interpretation without the benefit of adequate quantitative information presented by the authors.

AB Conservation tillage practices are being implemented by many farmers to conserve water and soil resources. These practices may modify the soil surface in ways that differentially effect dissipation of pesticide when compared to conventionally tilled fields. We measured volatilization of atrazine [2-chloro-4-ethylamino-6-isopropylamino-s-triazine] and alachlor [2-chloro-2'-6'-diethyl-n-(methoxymethyl) acetanilide] applied as either an experimental starch-encapsulated formulation or as a commercial formulation, containing atrazine as a wettable powder and microencapsulated alachlor, to adjacent no-till and conventionally tilled corn fields in Maryland. Both formulations were applied at the same rate; 1.7 kg ha(-1) for atrazine and 2.8 kg ha(-1) for alachlor. After 35 d, cumulative volatilization of alachlor from conventionally tilled fields was 14% of that applied for both formulations. Cumulative volatilization of alachlor was less from no-till fields with 9% of the commercial formulation and 4% of the starch-encapsulated formulation being lost. After 35 d, cumulative volatilization of the commercial formulation of atrazine from the conventionally tilled field was 9% of that applied compared with 4% of that applied to the no-till field. Starch encapsulation reduced volatilization losses of atrazine to <2% of that applied for both tillage practices. Starch encapsulation appears to be a viable formulation modification for reducing volatilization losses of herbicides, especially from no-till fields.

AB The fate of labeled N fertilizer applied to no-till corn (Zea mays L.) grown in nonweighing lysimeters was determined for 3 yr after application to evaluate NO3-N leaching losses from point-injection and conventional N management systems. In 1984, N-15-enriched double-labeled urea-ammonium nitrate solution (UAN) at 200 kg N ha(-1) was either surface-banded or knifed-in at the V1 growth state. It was also point-injected at either 200 or 125 kg N ha(-1) in split applications at the V1, V5, and V9 growth stages. Labeled N as NO3-N was detected in drainage from the bottom of the lysimeters (1.37 m deep) with the first significant rain (54 mm) 7 d after application for all treatments. Greatest labeled NO3-N concentrations, however, occurred with drainage in the fall after harvest and in the spring of 1985, the year after application. In 1985 when unlabeled N was applied using the same four systems, average labeled NO3-N concentrations and annual losses were the greatest and ranged from 1.0 to 5.1 mg L(-1) and from 1.7 to 6.8 kg ha(-1), respectively; the ratio of labeled NO3-N to total NO3-N ranged from 0.08 to 0.25. Labeled NO3-N concentrations, losses, and ratios were smallest for the 125 kg ha(-1) point injected-split system for each of 3 yr. For all systems, about one-fourth of the applied labeled N remained in the soil profile at the end of the study. Total recovery (77%) and recovery in grain (48% in 1984) were also greatest for the 125 kg ha(-1) point-injected system and least for the surface-banded system (64 and 30%, respectively). Unrecovered N was believed lost through denitrification and ammonia volatilization from soil or aboveground vegetation.

AB Atrazine is a commonly used herbicide in corn (Zea mays L.) growing areas of the USA. Because of its heavy usage, moderate persistence, and mobility in soil, monitoring of atrazine movement under held conditions is essential to assess its potential to contaminate groundwater. Concentrations of atrazine, deisopropylatrazine (DIA), and deethylatrazine (DEA) were measured in subsurface drainage and shallow groundwater beneath continuous, no-till corn. Water samples were collected from the subsurface drain (tile) outlets and suction lysimeters in the growing seasons of 1990 and 1991, and analyzed for atrazine and two principle degradates using solid-phase extraction and HPLC. In 1990, atrazine concentration ranged from 1.3 to 5.1 mu g L(-1) in tile-drain water and from 0.5 to 20.5 mu g L(-1) in lysimeter water. In general, concentrations of parent and degradates in solution were atrazine > DEA > DIA. Lesser levels of atrazine were measured in 1991 from Plots 2 and 4; however greater concentrations of atrazine (6.0-8.4 mu g L(-1)) were measured from Plot 5. Throughout the two growing seasons, atrazine concentration in Plot 5 the-drain water was greater than that of Plots 2 and 4, suggesting a preferential movement of atrazine. Concentrations of DIA and DEA ranged from 0.1 to 2.2 and 0.9 to 3.2 mu g L(-1), respectively, indicating that the degradation products by themselves or in combination with parent atrazine can exceed the maximum contaminant Level (mel) of 3 mu g L(-1) even though atrazine by itself may be <3 mu g L(-1). The deethylatrazine-to-atrazine ratio (DAR) is an indicator of residence time in soil during transport of atrazine to groundwater. In Plots 2 and 4, DAR values for tile-drain water ranged from 0.43 to 2.70 and 0.50 to 2.66, respectively By comparison, a DAR of 0.38 to 0.60 was observed in Plot 5, suggesting less residence time in the soil.

DT Article
ID PHOSPHATE; CARBONATE; KINETICS
AB Arkansas produces approximately one billion broilers (Gallus gallus domesticus) each year. Phosphorous runoff from fields receiving poultry litter is believed to be one of the primary factors affecting water quality in northwest Arkansas. Poultry litter contains approximate to 20 g P kg(-1), of which approximate to 2 g P kg(-1) is water soluble. The objective of this study was to determine if soluble P levels could be reduced in poultry litter with Al, Ca, and/or Fe amendments. Poultry litter was amended with alum, sodium aluminate, quick lime, slaked lime, calcitic limestone, dolomitic limestone, gypsum, ferrous chloride, ferric chloride, ferrous sulfate, and ferric sulfate, and incubated in the dark at 25 degrees C for 1 wk. The Ca treatments were tested with and without CaF2 additions in an attempt to precipitate fluorapatite. At the end of the incubation period, the litter was extracted with deionized water and water soluble P determined. Water soluble P levels in the poultry litter were reduced from >2,000 mg P kg(-1) litter to <1 mg P kg(-1) litter with the addition of alum, quick lime, slaked lime, ferrous chloride, ferric chloride, ferrous sulfate, and ferric sulfate under favorable pH conditions. Gypsum and sodium aluminate reduced water soluble P levels by 50 to 60%. Calcitic and dolomitic limestone were less effective. The results of this study suggest that treating litter prior to held application with some of these compounds could significantly reduce the amount of soluble P in runoff from litter-amended pastures. Therefore, chemical additions to reduce soluble P in litter may be a best management practice in situations where eutrophication of adjacent water bodies due to P runoff has been identified. Preliminary calculations indicate that this practice may be economically feasible. More research is needed, however, to determine any beneficial and/or detrimental aspects of this practice.

AB Denitrification losses and dissolved nitrous oxide concentration within a well- and poorly-drained soil under ryegrass (Lolium perenne L.) were measured for approximate to 12 mo. The soils received up to 252 kg N/ha as potassium nitrate in two equal amounts. Denitrification increased in March as the soil warmed to 5 to 7 degrees C with the highest rates occurring soon after N was applied. Approximately 30% of annual loss occurred within 2 wk of fertilization. Dissolved nitrous oxide concentration peaks corresponded to periods with elevated denitrification. On average, the poorly-drained soil denitrified the equivalent of 40% of applied N (up to 110 kg N/ha). Less than 2.5 kg/ha was denitrified from the mil-drained soil. The degree of anoxia in the measurement apparatus substantially effected measured denitrification rates. Consequently, it is important to know the relationship between redox in-situ and in the measurement apparatus.

AB Recent laboratory studies have shown that starch-encapsulation (SE) may reduce leachate losses of certain pesticides. This study compares field-scale mobility and persistence of SE-atrazine [2-chloro-4-ethylamino- 6-isopropylamino-s-triazine] and alachlor [2-chloro-N(2,6-diethylphenyl)-N-(methoxymethyl)acetamide] to that of a commercial formulation (CF) of atrazine and alachlor. The research site consisted of four (0.25 ha) fields. Two fields were under no-tillage management (NT) and two were under conventional tillage (CT). One field in each tillage system received SE-formulated atrazine and alachlor, while the others received CF-atrazine and alachlor. Chemical movement and persistence was determined by analysis of surface samples (approximate to 3 cm) taken immediately after application and 1.1-m soil cores collected seven times over 2 yr. No significant difference in herbicide residue levels was observed between NT and CT, but there was a herbicide formulation effect. Soil residue analysis suggests that SE-atrazine was more persistent and less mobile than CF-atrazine. Starch-encapsulated-alachlor was slightly more persistent than CF-alachlor, but no differences in mobility between formulations was observed. The differential field behavior between SE-herbicides is attributed to the faster release of alachlor from the starch granules. Increased atrazine persistence was attributed to the reduction of leachate losses. The reduction in atrazine leaching is likely due to the slow release from the starch granules and subsequent diffusion into the soil matrix where it is less subject to preferential how processes.

AB The tenacious behavior of Red-cockaded Woodpeckers (Picoides borealis) towards their cavity trees is well documented. A nestling Red-cockaded Woodpecker was observed to survive the felling of its cavity tree. The nestling subsequently fledged from the downed cavity. This observation suggests some Red-cockaded Woodpeckers will continue nesting efforts after a severe disturbance.

TI HISTORICAL USE OF BAMBOO CANE AS BLACKBIRD AND STARLING ROOSTING HABITAT
   - IMPLICATIONS FOR ROOST MANAGEMENT
SO JOURNAL OF FIELD ORNITHOLOGY
LA English
DT Article
AB The historical use of bamboo/cane as blackbird and starling roosting habitat was analyzed from U.S. Fish and Wildlife Service roost survey reports to assess the potential for shifting roosting populations away from objectionable urban sites where there may be nuisance or human health concerns. The following criteria were used to assess this potential: (1) frequent historical use by blackbirds and starlings compared with other habitat; (2) history of accommodating high bird densities on a limited area compared with other habitat; (3) history of repeated localized utilization by roosting blackbirds and starlings; (4) history of utilization over a wide geographic range; and (5) history of occupation by starlings and all major blackbird species. Of the diverse habitat historically reported to be used by wintering blackbirds and starlings for roosting, bamboo/cane uniquely appeared to meet all criteria as a widely used habitat that supports maximum densities of all primary roosting species. The possible ecological attractiveness of bamboo/cane as roosting habitat is discussed. Although the data are lacking to suggest that cane is sufficiently attractive to shift roosting behavior of blackbirds and starlings from objectionable sites, bamboo/cane is clearly a candidate for further research into this concept.

TI A NIGHT-LIGHTING TECHNIQUE FOR CAPTURING CORMORANTS
SO JOURNAL OF FIELD ORNITHOLOGY
LA English
DT Article
AB A night-lighting technique was developed, using a modified jon-boat, for capturing wintering Double-crested Cormorants (Phalacrocorax auritus) that roost in cypress trees surrounded by water. During November-March of 1990-1993, 115 cormorants were captured. In 1993, 33 cormorants were captured at the rate of 2.5 cormorants per hour of effort. The approximate cost of the fully equipped capture boat was $4000 (US). Only one bird was slightly injured from night-lighting and it is concluded that this is a safe and cost-effective way to capture wintering cormorants in the Delta region of Mississippi.

AB A method was developed to determine the number of pits in samples of red tart pitted (RTP) cherries. The method is based on pulping the sample in a modified kitchen blender and detecting pits either from the noise of pits rattling in the blender or by pouring the resulting pulp through a trap designed to retain the pits. The method is more rapid and convenient than the present method and allows the recovery of tested product as juice. Screening missed a total of 1 1/2 pits when 1 pit was added to each of 233 samples consisting of fresh, fresh frozen, individually quick frozen and bulk frozen RTP cherries.

AB Fruit of 'Climax' rabbiteye blueberries (Vaccinium ashei Reade) were irradiated by a linear accelerator at 0, 0.25, 0.5, 0.75, 1.0, and 1.25 kGy and evaluated for various quality attributes after storage for 1, 3, 7, or 14 days at 1C plus 2 days at 15C, respectively.  Weight loss increased during storage and averaged 4.2% after the final inspection and was not affected by irradiation dosage.  About 5% of total berries were decayed after 14 days at 1C, about 6% after the final inspection at 15C, but decay was not affected by the level of irradiation.  Electrolyte leakage, skin color, total soluble solids, acidity, and pH were also not affected by irradiation dosage.  There was a significant decline in berry firmness, flavor, and texture as dosage increased.  Berries treated at 1.0 kGy or above were softer and had lower flavor and texture preference scores than berries treated at lower dosages or nontreated berries.

Lowest free fat content (< 10%) was found in powders with 40% fat, encapsulated in sucrose. Angles of repose ranged from 37 to 46 degrees, and correlated with powder flow (p = 0.01). Bulk density was dependent on the encapsulant and declined with increasing fat content. Product density did not influence powder recovery through the cyclone of the dryer. Particle size distribution ranged from 20 to 120 mu m with 80% of the particles < 100 mu m. Powders with best physical properties were made with 40-50% butteroil encapsulated in sucrose.

AB S-Methyl-L-cysteine sulfoxide (SMCSO) was present in several cultivars of cabbage (Brassica oleracea) at 690-1,120 ppm. SMCSO was not inhibitory to Leuconostoc mesenteroides, but its hydrolysis product, methyl methanethiolsulfinate (MMTSO), was inhibitory. MMTSO was formed in fresh cabbage juice (CJ) and in a model system containing SMCSO and fresh cabbage (pH 4.0) precipitate, perhaps by cysteine sulfoxide lyase. Growth inhibition by 1 mM MMTSO was reversed by 5 mM dithiothreitol, cysteine, or reduced glutathione, but not by oxidized glutathione or thiamine.

The cloud pectin was solubilized to varying degrees in 6% citric acid, pH 2.5; in 10M urea-6% citric acid, pH 2.5; by hydrolysis of cloud protein with protease; and in sodium oxalate, pH 4.5. Much of the urea-solubilized pectin reprecipitated upon dialysis. The binding of orange cloud to amino paramagnetic latex particles demonstrated a clear association of cloud pectin with cloud protein. Simulation of orange juice processing conditions indicated that some of the cloud pectin arises from the pulp during processing. About 60% of the cloud pectin is soluble pectin that has become associated with cloud protein, 25-30% is calcium pectate and 15% is protopectin.

AB Commercial bakeries need a means to measure the dough-handling and bread-making functionality of wheat flour during processing. The feasibility of using near-infrared (NIR) reflectance spectrophotometry for such measurement was examined. Flour from hard red spring and hard red winter wheat were tested for: water absorption, dough mixing time, dough mixing tolerance, loaf height, internal grain appearance, and overall bake score. The ability of NIR to measure protein level, and/ or starch damage, as well as positive relationships between the two and water absorption, probably made it successful for modeling water absorption. Models for the remaining five indices were less accurate due to the complexity of interactions between protein, starch, and lipids, and inadequate instrument sensitivity.

Isoelectric point adjustment of whey protein with calcium ascorbate buffer increased WVP with increasing buffer concentration. The importance of vacuum application to minimize film pore size was identified using scanning electron microscopy. Polyethylene glycol, glycerol and sorbitol plasticizer concentration affected film WW. Determining the effects of relative humidity on WVP for plasticized whey protein films enabled prediction of film behavior under any water vapor partial pressure gradient.

AB We have developed an autosomal genetic linkage map of the chicken genome using a subpanel or 52 DNAs from a previously described reference backcross mapping population. The population derived from a cross of an inbred Red Jungle Fowl male and a highly inbred White Leghorn female. The backcross subpanel used was made up of offspring of a single F-1 male with four White Leghorn females. Ninety-eight markers consisting of classical and erythrocyte antigen genes, restriction fragment length polymorphisms, random amplified polymorphic DNA, and chicken CR1 repeat element polymorphisms were typed. Seventy-two of these markers were resolved into 19 linkage groups. Four of the linkage groups were assigned to chromosomes 1, 4, and 17. Four linkage groups were associated with linkage groups published earlier. Linkages within approximately 27 cM can be detected with a lod score of 3 with the panel used. The preliminary map contains approximately 590 cM within the linkage groups, and approximately 70% of the randomly selected markers fell in one of the groups; however, a considerable portion of the genome may remain outside of the existing linkage groups. These markers greatly expand the existing linkage map of the chicken genome.

AB A total of 1229 cultures, including 230 actinomycetes, 508 other bacteria, 12 fungi and 479 yeasts were screened for their ability to oxidize the isopropyl side chain of 2-phenyl propane (cumene).  Four strains of actinomycetes and six strains of bacteria but no yeasts were found positive in converting 2-phenyl propane to its oxygenated products.  Eight strains oxidized cumene through the alkyl side chain producing 2-phenyl-1-propanol.  Two Bacillus strains oxidized cumene to an oxygenated product.  Pseudomonas oleovarans NRRL B-3429 exhibited the highest alkyl side chain oxidation activity.  The optimum reaction conditions for strain B-3429 are:  25-degrees-C, pH 6.5 and 48 h of reaction.  Octane-grown cells of strain B-3429 produced higher product yields (about 7.2-fold) than the glucose-grown cells.  Prolonged incubation resulted in an increase in 2-phenyl-1-propionic acid production at the expense of 2-phenyl-1-proponal.  The yield of 2-phenyl-1-proponal plus 2-phenyl-1-propionic acid was 5.1%.  Reaction in the presence of methanol favored the accumulation of 2-phenyl-1-propionic acid and also increased the total yield.  (The yield of 2-phenyl-1-propanol plus 2-phenyl-1-propionic acid was 14.9%).  Structures of the reaction products were confirmed by GC/MS and GC/IR analyses.  Products contained 92% R(-) isomer.

AB Prenatal transmission of ovine lentivirus (OvLV) was studied in 85 ewes and their offspring. The animals were from a flock with endemic OvLV infection and 49 (58%) had serum antibodies to OvLV. Blood was collected from all lambs before they nursed. Using the polymerase chain reaction (PCR), OvLV DNA was detected in peripheral blood mononuclear cells of 13 (11%) of 117 lambs, including two sets of twins. Mothers with OvLV-infected lambs (n = 11) were younger (mean, 2.5 years) and had fewer pregnancies (mean, 2.4) than seropositive ewes (3.2 years and 3.2 pregnancies; P < .05). Of mothers with OvLV-positive lambs, 4 had plasma antigenemia (mean, 31.3 +/- 2.1 ng/mL OvLV) in conjunction with indeterminate antiviral antibody responses by immunoblotting. These results suggest that maternal factors (age and parity) and host-virus interactions (antiviral antibody and antigenemia) are important risk factors in prenatal transmission of OvLV.

AB The sunflower stem weevil, Cylindrocopturus adspersus (LeConte), overwinters as a mature larva at the base of the stalk and in the root crown of cultivated sunflower plants. Sunflower stalks from fields known to be infested with C. adspersus larvae were collected in southeastern North Dakota in October 1991. Larvae from stalks kept outdoor accumulated a high whole-body concentration of trehalose (up to 69 mu g/mg wet wt) at the expense of glycogen with the onset of winter followed by a partial reconversion of trehalose to glycogen with the onset of spring. Larvae from stalks acclimated to 0 degrees C also accumulated a high level of trehalose (similar to 69 mu g/mg wet wt) with a concomitant decrease in glycogen. Those larvae from stalks kept at 20 degrees C showed an initial sharp increase in whole-body trehalose that then stabilized but a concentration well below that of larvae acclimated to 0 degrees C. This indicates that there exists in the larva an underlying developmental component to trehalose accumulation which is further enhanced by low temperature (0 degrees C) exposure. The mean temperature of crystallization (T-c) of larvae exposed to outdoor conditions showed an abrupt drop from October (-25.0+/-1.3 degrees C) to November (-28.2+/0.6 degrees C) with a minimum in February (-29.1+/-0.3 degrees C). The level of trehalose accumulated by the sunflower stem weevil larva is to our knowledge the highest reported in an overwintering insect.

AB The pattern of in vitro toxicity of activated toxins from several classes of entomocidal inclusion genes from Bacillus thuringiensis was measured using eight established cell lines from lepidopteran insects. Protoxins representing CryIA(b), CryIA(c), and a mixture of all three CryIA toxins (subtypes a, b, and c; from B. thuringiensis subsp. kurstaki HD-1) were compared with the protoxin representing CryIC in a bioassay which measured the viability of cultured insect cells upon exposure to entomocidal toxin proteins. The responses of the various cell lines were very specific toward the individual toxin proteins. CryIC activated protoxin was toxic for cells of Manduca sexta, Plodia interpunctella, and to a lesser extent Spodoptera frugiperda. CryIA(b) and CryIA(c) proteins were toxic toward M. sexta but relatively nontoxic for P. interpunctella or S. frugiperda. The toxicity of CryIA(b), CryIA(c), and the composite CryIA activated toxins toward cells of Choristoneura fumiferana varied substantially, with the CryIA mixture being slightly more toxic than CryIA(c) alone. CryIC toxin had no effect toward C. fumiferana cells. Probit regression analysis of dose-response relationships between insect species and crystal protein composition demonstrated specific patterns of toxicity which may be related to membrane-receptor site binding by specific toxins. Membrane binding analysis of I-125-labeled CryIA(b), CryIA(c), and CryIC toxins to insect cells from three of the cell lines yielded high specific binding only with bl. sexta cells toward CryIA(c) toxin. Lower levels of binding were observed with CryIA(b) and CryIC toward cells of C. fumiferana and P. interpunctella. Although relatively low binding levels for CryIC were observed with P. interpunctella cells, toxicity was high for these cells. The results suggest that at least for CryIC, binding may be unrelated to toxicity in cultured insect cells. (C) 1994 Academic Press, Inc.

AB The link between sun exposure and skin cancer is well established, but the mechanism of photocarcinogenesis is still incompletely understood. In vitro experimentation has shown that induction of the c-fos proto-oncogene occurs in cultured human keratinocytes after ultraviolet exposure, and c-Ha-ras mutations are commonly present in human skin neoplasms removed from chronically sun-exposed sites. In the present study, the effect of UV irradiation on the expression of these two proto-oncogenes was examined. The sun-protected volar forearm of six subjects was exposed to a standardized erythemogenic dose of solar-simulated light, and punch biopsies were obtained after 1 h and 24 h from the irradiated area and a nearby shielded area. Expression of c-fos, determined by in situ hybridization of histologic cross-sections, was detected in the basal and lower epidermal layers in all biopsies. However, at 1 h there was a marked increase that returned to baseline by 24 h. c-Ha-ras mRNA could not be detected by riboprobe hybridization in any of the biopsy specimens. Our data demonstrate transient induction of c-fos but not c-Ha-ras expression, at least at the timepoints studied, following a modest UV exposure in normal skin. This phenomenon may lead to the subsequent constitutive over-expression and super-inducibility of c-fos observed in cultured keratinocytes derived from photodamaged skin and may facilitate the development of skin cancer.

TI RESULTS OF PARSHALL FLUME TESTS
SO JOURNAL OF IRRIGATION AND DRAINAGE ENGINEERING-ASCE

DT Article
AB Presented are: (1) A reanalysis of Parshall's original experimental data obtained for the improved Venturi (Parshall) flume; and (2) a reanalysis of data obtained by the writer during model tests of the Parshall flumes at the rate measuring stations installed by the U.S. Department of Agriculture's Soil Conservation Service (SCS) on the Waco, Tex., Blacklands experimental watershed. Parshall's and the Waco data were originally analyzed graphically to develop rating equations. The reanalysis used the least-squares method. The reanalysis shows that in the head-discharge equation the Waco coefficient and exponent do not vary with flume size, whereas Parshall's exponent varies with flume size for the 0.30 m (1 ft) to 2.44 m (8 ft) flumes and the coefficient varies with flume size for the 3.05 m (10 ft) and larger flumes. The quality of both sets of data is excellent: no explanation has been found for the albeit small differences. The reanalysis lends confidence that the equations presented by Parshall predict the discharge to within the 5% accuracy claimed by Parshall. Similar accuracy is obtained using the writer's equations. The Waco data show that the entrance wingwalls should be curved and that the head-discharge relationship is valid for heads as low as 18 mm (0.06 ft).

TI CORRECT FORM OF HALL TECHNIQUE FOR BORDER IRRIGATION ADVANCE
SO JOURNAL OF IRRIGATION AND DRAINAGE ENGINEERING-ASCE
LA English
DT Article
AB The Hall technique for computing stream advance down an irrigated border strip is shown to be inconsistent in the selection of numerical parameters for approximating infiltrated volume. This inconsistency leads to violation of mass conservation and to error in computed advance. By viewing it in dimensionless terms, the behavior of this error is demonstrated over the practical range of variation of border-irrigation parameters with a Kostiakov infiltration formula and Manning roughness formula. It is shown to vary from insignificant magnitudes under 1% to well over 10%. A correction term to neutralize the inconsistency is presented. An alternate formulation free of the inconsistency and suitable for modern high-speed computers working with a reasonably large number of significant figures is presented. Errors stemming from the basic physical assumption-constant average depth of surface water-are not addressed.

TI SEASONAL DISTRIBUTIONS OF PEAK FLOWS FROM SMALL AGRICULTURAL WATERSHEDS
SO JOURNAL OF IRRIGATION AND DRAINAGE ENGINEERING-ASCE
LA English
DT Article
AB Knowledge of seasonal distributions of peak runoff rates is needed for use with watershed models, and for the development of new techniques of estimating peak flow rates and their frequencies of occurrence from small agricultural watersheds. The peak flows in 312 station years of data from seven small agricultural watersheds in Ohio were analyzed to determine the seasonal and land-use distributions of peak flows and their return periods. The assumptions often made when using design storms that peak flows occur during the seasons of highest rainfall intensities was largely confirmed, but there were exceptions. Between 92 and 94% of the peak flows, regardless of land-use and soil type, with return periods greater than two years, occurred during the seasons of highest rainfall intensities. A similar seasonal distribution of peak flows was found from an analysis of specific agricultural land uses. More peak flows occurred during the winter season for flows with return periods smaller than about five years for some land uses. Seasonal distributions of peak flows greater than five years are largely independent of soil type and land use, allowing extrapolation of results beyond the study area in Ohio.

TI MAXIMUM SURFACE STORAGE PROVIDED BY CROP RESIDUE
SO JOURNAL OF IRRIGATION AND DRAINAGE ENGINEERING-ASCE
LA English
DT Article
ID TILLAGE
AB Small ponds created by crop residue serve to store water on upland areas. The present study is conducted to identify the maximum surface storage provided by crop residue. Equations for estimating surface storage arc derived assuming that residue elements were oriented end to end, at uniform intervals, in a direction perpendicular to flow. Separate equations are developed for conditions where average slope was greater than or equal to residue cover, or less than residue cover. Both equations relate average surface-storage depth to residue cover, residue diameter, and average slope. Data to test the reliability of the equations are obtained in a laboratory investigation. Artificial residue elements are glued onto a 1-m2 test section positioned at slopes of 1%, 10%, or 20%. Four sizes of residue elements and three surface-cover conditions are examined. Surface-storage depth for each experimental condition is measured. Close agreement is found between predicted and measured surface-storage values. Surface storage occurring under field conditions may bc substantially less than the estimates obtained using the predictive equations.

ID NORTH-AMERICA
AB Aedes albopictus (Skuse) lays eggs refractory to hatching in response to several environmental cues. The goal of this statistical treatment was to quantify the role and interaction of latitude and country of origin (japan and the United States), photoperiod, rearing/holding temperature, and a newly identified element, elevation of the site of origin, with critical photoperiod (C(pp)). We also describe the development of an equation relating the incidence of diapause to daylength, rearing/holding temperature, and latitude and elevation of the site of origin, an equation useful in the development of a simulation model of the population dynamics and distribution of Ae. albopictus in North America. The analysis indicated that elevation from 0 to 300 m is significantly correlated with C(pp). The results also corroborate earlier conclusions that, on the basis of a shallower geographical cline in photoperiodic response in the United States, North American strains of Ae. albopictus have a temperate origin in Asia and indicate that the rapid spread of this mosquito within the United States via the distribution of used tires resulted in founder populations that were only partially adapted in diapause response to local conditions.

AB To clarify the risk of pastured livestock for exposure to Ixodes scapularis Say (Acari: Ixodidae), we estimated the host-seeking activity of nymph and adult blacklegged ticks at the woods-pasture interface on horse farms in Maryland. Parallel linear transects of 100 m length and 1 in width were sampled repeatedly in pastures and adjacent woodland locations during periods of nymph (early summer) and adult (fall and spring) host-seeking activity. Data collected over two successive years indicated that adults were most abundant in ecotonal vegetation at the wood's edge, median values of 6.4 and 2.2 ticks per 100 m2 sample during fall and 1.2 and 0.5 ticks per 100 m2 sample for spring periods. Nymphs were most abundant in the shallow woods location, median values of 4.2 and 35 ticks per 100 m2 sample, followed by the deep woods and wood's edge locations. Host-seeking nymph and adult black-legged ticks also were collected repeatedly in pasture vegetation, median values ranging from 0.2-0.8 ticks per 100 M2  sample,  with a progressive decrease in abundance from the fenceline into pasture. Adults and nymphs both were uncommon more than 5 m into pastures, where only two adults and one nymph were captured in 84 (fall and spring) and 24 (summer) 100-m2 samples, respectively. Levels of adult and nymph host-seeking in pasture vegetation were spatially correlated with tick abundance in adjacent woodlands when ticks were numerous; this condition presumably reflects a spillover of ticks from the woodlands-based population. These findings expand knowledge of blacklegged tick host-seeking behavior and establish a basis for the exposure of pastured livestock to nymphs and adults.

AB The vertical and horizontal spatial patterns of a naturally occurring population of the entomopathogenic nematode Steinernema riobravis (Rhabditida: Steinernematidae) were investigated in corn field soil by laboratory and field bioassays. This nematode appears to be endemic to the Lower Rio Grande Valley of Texas, where it was found parasitizing prepupae and pupae of both corn earworm, Helicoverpa zea, and fall armyworm, Spodoptera frugiperida (Lepidoptera: Noctuidae). Corn earworm prepupa was the bioassay host used to detect S. riobravis from soil in previously har-vested corn plots. Steinernema riobravis occurred at soil depths of 5-30 cm. The maximum nematode density was in the upper 20 cm of soil, and the lowest density occurred at soil depth of 25-30 cm. The field and laboratory bioassays performed on the top 20 cm of soil resulted in S. riobravis-infected corn earworm of 49 and 34%, respectively, whereas at 25-30 cm soil depths 11 and 4.5% of the H. zea were infected, respectively. The horizontal spatial pattern of this nematode was patchy or aggregated. Our study provides new information on the spatial pattern of S. riobravis in its natural habitat and indicates the need to augment its natural biocontrol efficacy.

AB Temperature gradient fluctuations that occur naturally as a result of heating and cooling of the soil surface were reproduced within 15-cm-d, 15-cm-long acrylic tubes filled with moist sand. Sunny and rainy periods during the late summer in eastern Texas were simulated. Five ecologically different nematode species were adapted to fluctuating temperatures for 20-36 hours at a simulated depth of 12.5 cm before being injected simultaneously into the centers of tubes at that depth. When heat waves were propagated horizontally to eliminate gravitational effects, the movement of Ditylenchus phyllobius, Steinernema glaseri, and Heterorhabditis bacteriophora relative to the thermal surface was rapid and largely random. However, Rotylenchulus reniformis moved away from and Meloidogyne incognita moved toward the thermal surface. When heat waves were propagated upward or downward, responses to temperature were the same as when propagated horizontally, irrespective of gravity. The initial direction of movement 1.5 hours after introduction to 20-cm-long tubes at five depths at five intervals within a 24-hour cycle indicated that M. incognita moved away from and R. reniformis moved toward the temperature to which last exposed. Differences in movement of the five species tested relative to gravity appeared related to body length, with the smallest nematodes moving downward and the largest moving upward.

AB Rates of penetration and development of Meloidogyne incognita race 4 in roots of resistant (inbred Mp307, and S4 lines derived from the open-pollinated varieties Tebeau and Old Raccoon) and susceptible (Pioneer 3110) corn genotypes were determined. Seedlings grown in styrofoam containers were inoculated with 5,000 eggs of M. incognita. Roots were harvested at 3-day intervals starting at 3 days after inoculation (DAI) to 27 DAI and stained with acid fuchsin. Penetration of roots by second-stage juveniles U2) at 3 DAI was similar for the four corn genotypes. Meloidogyne incognita numbers in Tebeau, Old Raccoon, Mp307, and Pioneer 3110 peaked at 12, 12, 15, and 27 DAI, respectively. Nematode development in the resistant genotypes was greatly suppressed compared to Pioneer 3110. Resistance to M. incognita in these genotypes appears to be expressed primarily as slower nematode development rather than differences in J2 penetration.

AB A study was conducted in growth chambers to examine main factor and interaction effects of Tylenchorhynchus nudus nd Magnaporthe poae on creeping bentgrass and annual bluegrass at 24, 28, and 30 C. A 2 x 2 factorial arrangement of treatments was employed with presence and absence of T. nudus and M. poae as factors with each temperature run separately for 14 or 18 days. Tylenchorhynchus nudus decreased bentgrass and annual bluegrass root length at all three temperatures. Magnaporthe poae had no effect on bentgrass root length at 24 C, increased root length at 28 C, and suppressed root growth at 30 C. Magnaporthe poae had no effect on annual bluegrass root length at 24 and 28 C but suppressed root growth at 30 C. A significant interaction between M. poae and T. nudus occurred only on bentgrass at 28 C and 30 C; at these two temperatures, M. poae did not act independently of T. nudus.

AB Feeding a vitamin E-deficient diet increases pathology in hearts of mice infected with a myocarditic coxsackievirus B3 (CVB3/20). Hearts from infected mice fed a vitamin E-deficient diet rich in highly unsaturated fat (menhaden oil) exhibited more severe pathology than hearts from infected mice fed a vitamin E-deficient diet based largely on saturated fat (lard). Furthermore, a cloned and sequenced amyocarditic coxsackievirus B3 (CVB3/0), which caused little or no pathology in the hearts of vitamin E-supplemented mice, induced extensive cardiac pathology in vitamin E-deficient mice. In infected mice, both mitogen and antigen responses were depressed by vitamin E deficiency, although neutralizing antibody responses were unaffected. Natural killer cell responses were comparable in infected mice fed a lard-based diet with or without supplemented vitamin E. However, a menhaden oil-based diet, whether supplemented with vitamin E or not, significantly depressed natural killer cell activity in infected mice compared with mice fed the lard-based diet. Coxsackievirus B3/0 recovered from the heart of a vitamin E-deficient donor mouse, passaged one time onto HeLa cells, caused significant heart damage when passed back into vitamin E-supplemented recipient mice, demonstrating that the amyocarditic CVB3/0 had changed to a virulent phenotype. Enhanced virulence was also seen with CVB3/20 virus similarly passaged in a vitamin E-deficient donor. Our work demonstrates the important role of host nutritional antioxidant status in determining the severity of certain viral infections.

AB The de novo induction of roots in tomatoes (Lycopersicon esculentum) Mill. cvs. ''Early-pak-7,'' ''Ace,'' ''Better Boy,'' ''Roma,'' and ''Parks' Whopper'') by fumonisin B1, a mycotoxin produced by Fusarium moniliforme J. Sheld., was studied. In graded dosages of fumonisin B1, detached stems of the cultivars ''Ace,'' ''Better Boy,'' and ''Roma'' were induced to produce calluses and roots earlier than controls. The cultivar ''Ace'' was especially responsive to this mycotoxin, and following a single application, callus initiation was observed to occur within a 24-48-h period and roots were produced as early as 72 h with 10 mug/shoot or as late as 96 h with low dosages. The control plants of all cultivars were completely negative for a rooting response during this time. Some cultivars treated with fumonisin B1 showed either no response or developed signs of phytotoxicity. Those cultivars that were stimulated to produce roots did not show signs of phytotoxicity, except at dosages of 0.5 mg/plant and higher. One cultivar did not show any signs of phytotoxicity nor was it induced to root. The ability of fumonisin B1 to affect the accumulation of calcium in other systems, and its structural similarity to sphingosine suggest that the induction of adventitious roots may be a calcium-dependent process.

AB Previous studies suggest that nitrogenous transport compounds may be metabolized in the pedicel (basal maternal tissue) of the developing maize (Zea mays L.) kernel. In this report, excised tassel-seed tunicate (Ts-5 Tu) kernels were tested as a model in vitro kernel system to study the metabolic fate of [C-14]aspartate within the pedicel and the endosperm. Glume-covered kernels of Ts-5 Tu maize are born on individual elongated stalks and can be removed from the parent plant without damage to the basal kernel tissues. Radiolabeled aspartate supplied to excised Ts-5 Tu kernels in a 30-min pulse was rapidly metabolized within the pedicel, with 60% of the C-14 recovered in the acidic (organic-acid-containing) fraction at the beginning of the chase period. By 1 h into the chase period, both glutamine and glutamate were more heavily labeled than aspartate. In the endosperm, 60% of the ethanol-soluble, aspartate-derived C-14 was recovered in the basic (amino acid-containing) fraction, 35 % in the acidic fraction, and the remainder in the neutral (sugar-containing) fraction. Radioactivity in glutamate plus glutamine accounted for 70% of the C-14 contained in the basic fraction of the endosperm. Inclusion of 2 mM methionine sulfoximine, an irreversible inhibitor of glutamine synthetase (GS), had little effect on pedicel aspartate catabolism but did inhibit incorporation of aspartate-derived C-14 into glutamine in the pedicel, resulting in more C-14 being taken up by the endosperm as organic acids and less being incorporated into the prolamin fraction. It was concluded that the results obtained using Ts-5 Tu kernels incubated in vitro reflect more closely what occurs in the intact plant than those obtained with cob-borne kernels. The role of pedicel-amino-acid metabolism in maize-kernel nitrogen assimilation is also discussed.

Love] in May 1989 and 1990 at Logan, Utah. Spaced plants were randomly arranged in 4 paddocks which were grazed once by 2 animals in late spring each year. Number of bites and number of visits were recorded for each entry in each paddock for the 2 animals individually. Cattle preferred Hycrest and Nordan crested wheatgrasses both years. Number of bites per plant for crested, thickspike, Snake River, and bluebunch wheatgrasses averaged 9.1, 4.3, 3.1, and 4.1, respectively, in 1989 and 6.7,3.3, 3.5, and 3.6, respectively, in 1990. Number of visits was highly correlated with number of bites across entries. Grazing preference among entries was more highly correlated with biomass score and canopy height than basal area or maturity. Cattle preferred crested wheatgrass over the native wheatgrasses tested here during the spring grazing season.

AB Many ranchers claim that if a cow starts eating locoweed, she will teach others to eat it. Three grazing trials were conducted to evaluate the role of social facilitation in starting cattle to graze locoweed. The first trial was conducted near Gladstone, N.M., using mature cows grazing woolly locoweed (Astragalus mollissimus var. mollissimus Torr). The second trial was conducted on the Raft River Mountains in northwestern Utah, using yearling cattle grazing white locoweed (Oxytropis sericea Nutt). The third trial was conducted to determine if aversion-conditioned yearling cattle would consume white locoweed when placed with cattle that were eating locoweed (loco-eaters). Cattle conditioned to eat locoweed and naive animals in trials 1 and 2 first grazed in separate pastures to evaluate their initial acceptance of locoweed. The groups in the respective trials then were placed together to evaluate the influence of social facilitation on locoweed consumption. Locoweed consumption was quantified by bite count. Naive cattle in trials 1 and 2 sampled small quantities of locoweed while grazing separately. However, they greatly increased locoweed consumption when placed with the loco-eaters. Aversion-conditioned cattle in trial 3 did not consume locoweed while grazing separately. When placed with loco-eaters, they gradually increased consumption of white locoweed, in contrast to the immediate acceptance of locoweed by naive cattle in trials 1 and 2. The aversion extinguished and averted animals eventually accepted white locoweed at levels comparable to loco-eaters. Results of this study demonstrate that social facilitation can cause cattle to start eating locoweed.

AB Estimates of forage production for long-term ungrazed, lightly, moderately, and heavily grazed treatments (0, 20,40,60% removal of annual forage production) established in 1939 in shortgrass steppe communities were subjected to multiple regression analyses to assess long-term temporal trends resulting from grazing and short-term sensitivities to abiotic factors. Average production based upon all data from 1939-1990 was 75,71, 68, and 57 g m-2 yr-1 for ungrazed, lightly, moderately, and heavily grazed treatments, respectively. Variability in forage production was explained mostly by cool-season precipitation, and magnitude of forage production was more sensitive to annual fluctuations in precipitation than to long-term grazing treatments. Production per unit increase of precipitation was greater for cool-season than warm-season precipitation, but only when cool-season precipitation was above average. This was attributed to differences in evaporative demand of the atmosphere resulting in different utilization-efficiencies of small and large rainfall events in the 2 seasons. Based upon a regression model constructed using data from 1939 through 1962, forage production was not affected by grazing to 20 to 35% removal. For pastures of average relative productivity, grazing at 60% level of consumption for 25 years resulted in a 3% decrease in forage production in wet years and a 12% decrease in dry years. Estimates of productivity after 50 years of heavy compared to light grazing treatment were -5 and -18% for wet and average years of precipitation, respectively.

AB Japanese brome (Bromus japonicus Thunb.), an alien annual grass, is an important component of some northern mixed-prairie communities. Understanding the relationship between environment and population dynamics for this species is critical for efficient management of infested ranges. Our objective was to determine the germination pattern of seed harvested in the Great Plains with varying collection dates, storage conditions, incubation temperatures, and light regimes. Seeds were collected from inflorescences (nondisseminated seed) during July in Oklahoma and Montans and during November and December in Montana. July collections were stored in paper sacks in a laboratory, and November and December collections were divided into thirds and stored in an unheated warehouse, oven-dried at 46-degrees-C, or frozen at - 18-degrees-C. Seeds were germinated in 2 regimes, where temperatures alternated every 12 hours and light was provided during the 12 hours of high temperature. One regime provided 10 days of prechilling (0 and 10-degrees-C) followed by 18 days of a warm temperature (8 and 23-degrees-C) (chilling). Another regime consisted of 28 days of the warm temperature (warm). Samples of seeds were also imbibed in the warm regime with 12-hour or intermittent periods of light. July collections germinated rapidly to > 90% regardless of temperature. November and December collections stored in the warehouse germinated > 70% in the warm regime, but germination was reduced to < 20% with chilling, suggesting secondary dormancy was induced by imbibition at 0-degrees-C. Oven drying was the only treatment that consistently reduced maximum germination. Darkness enhanced 7-day germination, but light improved 28-day germination, and more recently collected seeds were more sensitive to light than older ones. These and earlier findings from Kentucky suggest Japanese brome seeds grown in different locations respond similarly to changing environmental conditions.

AB Development of plant materials adapted to the demands of a harsh environment and conditions created by standard planting practices has resulted in improved seedling establishment for some species. Bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] Love) is an important native bunchgrass often planted in the Intermountain and Pacific Northwest regions. Though cultivars have been developed, this species continues to have a reputation for weak seedlings. Forty-seven accessions of bluebunch wheatgrass collected from naturally occurring populations in 9 geographic regions and the cultivar 'Goldar' were evaluated for germination rate, seedling emergence and growth, and seed weight. Significant differences in seed weight and germination rate at optimum (15/25-degrees-C) and cold (1-degrees-C) temperatures were observed. Seedling emergence from a 4-cm depth ranged from 5 to 66%. Mean dry shoot weight 28 days after planting varied among accessions by a factor of 6. Simple correlations between seed weight and percentage emergence (r = 0.62) and seed weight and mean shoot weight (r = 0.63) indicate seed weight could be used as a preliminary screening test for these traits. Seed weight was not useful in predicting germination rate. Results suggest establishment success may be improved through careful selection for traits associated with seedling vigor.

AB Reestablishment of spiny hopsage (Grayia spinosa [Hook.] Moq.) in the shrub steppe requires development of appropriate seeding technology. We examined the effect of planting date and seedbed environment on germination and seedling establishment of 2 seed sources at 2 southwestern Idaho sites. Seedbeds were prepared by rototilling. In 1987-88, seeds collected in 1986 were drilled at 66 viable seeds m-1 of row at Birds of Prey in late fall, winter, and early spring and at Reynolds Creek in late fall, early spring, and late spring. Seeds collected in 1986 and 1988 were broadcast at 400 viable seeds m-2 at both sites in late fall, early spring, and late spring 1988-89. Seeds in nylon bags were also planted at each site in late fall, winter, and early spring in 1987-88 and in late fall, winter, early spring, and late spring in 1988-89. On each succeeding planting date and in early summer, 5 bags of each seed source from each of the earlier planting dates were recovered. Water content, viability, and germination were compared among seeds from previous plantings and control seeds stored in the laboratory. Each year, first-year seedling establishment at both sites was favored by late fall compared to other planting dates. In 1988, seedlings established only from late fall plantings at a density of 1 m-2 at each site. In 1989, late fall planting at the 2 sites increased seedling establishment 6 (51 vs 8 M-2) and 20 (41 vs 2 m-2) times compared to early spring planting. Germination was generally greater for seeds incubated at field sites compared to controls. Germination total and rate increased 6-11 times and 13 days from late fall 1987 to early spring 1988, 1-6 times and 4 and 9 days from winter 1988 to early spring 1988,17 times and 10-11 days from late fall 1988 to winter 1989, and 4-7 times and 11 days from winter 1989 to early spring 1989. Late fall or early winter planting is essential to permit early spring germination when surface soils are moist.

TI COMPUTING THE WIND ERODIBLE FRACTION OF SOILS
SO JOURNAL OF SOIL AND WATER CONSERVATION
LA English
DT Article
AB Chepil, Woodruff, and Siddoway, developers of the wind erosion equation (WEQ), suggest that the wind erodible fraction of any soil can be determined by dry sieving a sample of the surface soil.  The data base of soil information for the wind erosion equation was primarily from the Central Great Plains.  As other areas used the WEQ, questions about the erodible fraction based on soil texture alone began to surface.  To test soils outside the Great Plains, more than 3,000 samples have been sieved to identify the relationships between the erodible fraction of soils and the physical and chemical properties of the soil.
   From these results, the erodible fraction was computed from the percentage of sand, percentage of silt, sand/clay ratio, organic carbon, and calcium carbonate.  A correlation coefficient of 0.82 was obtained between computed erodible fraction using soil physical and chemical properties with average measured erodible fraction from standard compact rotary sieving from sites with at least 20 samples.  The erodible fraction of dryland soils was reduced an average of 14% and of irrigated soils 24% with moldboard plowing.

TI SOIL ORGANIC-MATTER AND AVAILABLE WATER CAPACITY
SO JOURNAL OF SOIL AND WATER CONSERVATION
LA English
DT Article
AB For the last 50 years, the consensus view among researchers has been that organic matter (OM) has little or no effect on the available water capacity (AWC) of soil.  The historical development of this viewpoint is traced.  It is argued that the the literature on this subject has been misconstrued and that the consensus view is wrong.  In addition to a critical review of the literature, published data were evaluated to assess the effect of OM content on the AWC of surface soil within three textural groups.  Within each group, as OM content increased, the volume of water held at field capacity increased at a much greater rate (average slope = 3.6) than that held at the permanent wilting point (average slope = 0.72).  As a result, highly significant positive correlations were found between OM content and AWC for sand (r2 = 0.79***), silt loam (r2 = 0.58***) and silty clay loam (r2 = 0.76***) texture groups.  In all texture groups, as OM content increased from 0.5 to 3%, AWC of the soil more than doubled.  Soil OM is an important determinant of AWC because, on a volume basis, it is a significant soil component.  In this study, one to 6% OM by weight was equivalent to approximately 5 to 25% by volume.

AB The interaction of various tillage and crop sequences on the distribution of soil organic carbon (C) and inorganic nitrogen (N) is important for predicting changes in soil physical and chemical properties and potential environmental impacts of soil and crop management.  This study was conducted to determine the distribution of organic C, nitrate (NO3-N) and ammonium (NH4-N) in a soil with various tillage methods and crop sequences.  A tillage experiment was started in 1978 with treatments of chisel, disk, no-till, plow, ridge-till, and sub-soil.  In 1985, each tillage plot was divided into two subplots to which two crop sequences of continuous corn [Zea mays L.] (C-C), and soybean [Glycine max (L.) Merr.]-corn (S-C) were assigned.  Nitrogen fertilizer was applied at a rate of 100 kg N ha-1 y-1 when plots were planted to corn.  In the spring and autumn of 1989, soil samples were taken from crop sequences and tillage plots to a depth of 1.5 m in 0.3 m increments for determination of NO3-N, and NH4-N contents.  Soil samples were also collected from 0-10, 10-20, 20-40, 40-60, 60-80, 80-100, 100-150, 150-200, 200-250, and 250-300 mm soil depths for organic C determination.  Multivariate analysis of variance (MANOVA) was used to analyze the data taken from different soil depths.  Organic C concentration was greatest at 0-10 mm soil and decreased with increasing soil depth.  Organic C was greatest for no-till and was least for sub-soil.  Greater residue in C-C was associated with greater soil organic C than S-C.  Organic C quantity (kg ha-1 300 mm-1) followed the same trend as organic C concentration.  The plow treatment had the greatest NO3-N quantity in the 0-0.3 m soil depth.  All tillage systems had similar NO3-N amounts in deeper soil.  NH8-N content of soil was not influenced by tillage or crop sequences.  Soil organic C was related to both the amount of residue produced and left on the soil surface after harvest and also to the degree of soil surface disturbance.  Nitrate-N was affected more by tillage and crop sequence systems than was ammonium-N.

TI SEPARATING FACT FROM ARTIFACT IN CHANGES IN NUTRIENT INTAKE OVER TIME
SO JOURNAL OF THE AMERICAN DIETETIC ASSOCIATION
LA English
DT Article
AB Objective To determine whether the differences between the procedures and nutrient databases used in the 1977-1978 Nationwide Food Consumption Survey (1977-78 NFCS) and those used in the 1987-88 NFCS could notably affect the estimated mean nutrient intakes.
   Design This was a split-sample field experiment. Seventy-two area segments were randomly selected; 10 housing units were selected in each segment and randomly assigned to one of two experimental groups.
   Setting The study took place in the Philadelphia, Pa, metropolitan area.
   Subjects The subjects were 697 women aged 20 to 49 years.
   Treatment Group A was interviewed using 1987-88 NFCS 24 hour recall procedures and their nutrient intakes were calculated using the 1987-88 NFCS food codes, weight conversion factors, and nutrient database. Group B was interviewed using 1977-78 NFCS 24-hour recall procedures and nutrient intakes were calculated four ways using various combinations of 1987-88 and 1977-78 NFCS food codes, weight conversions, and nutrient database.
   Main outcome measure Mean intakes of food energy and 14 nutrients were calculated.
   Statistical analysis We used two-sample, multivariate t tests; univariate t tests; univariate repeated measures analysis of variance; and univariate paired t tests.
   Results Changes in the nutrient database caused by improved analytic techniques and increased number of foods sampled were great enough to warrant revising the 1977-78 NFCS estimated intakes for iron, magnesium, and vitamins B-6 and B-12. Changes in intake of fat, vitamin A, and thiamin, however, were caused by real changes in foods so no revisions were necessary for these nutrients. Other nutrients were unaffected.
   Conclusion When considering changes in nutrient intake over time, it is important to correct the earlier food composition estimates so that they accurately reflect the composition of foods at the time they were consumed. This requires preserving the real differences in the composition of foods while correcting for artifactual differences attributable to improvements in the quality of nutrient data.

AB Female Culicoides variipennis were fed at 1-18 days postinoculation on calves treated with a commercial injectable formulation of ivermectin at the recommended mte of 200 mug/kg of body weight. There were no significant differences between treated and untreated animals in the survival rate of the flies at 24 h and 48 h postinoculation and the number of eggs produced per living female. There was a significantly greater mean hatch mte of eggs from flies fed on the untreated animals (65.8%) than those fed on the treated animals (52.8%). The recommended use rate of ivermectin does not appear to provide significant mortality for female C variipennis, nor affect egg deposition or hatch mte sufficiently to reduce vector populations.

SO JOURNAL OF THE AMERICAN MOSQUITO CONTROL ASSOCIATION
LA English
DT Article
AB An iridescent virus is found at low prevalence in populations of Aedes taeniorhynchus. Attempts at experimental transmission produced low levels of infection, regardless of the dosage applied. In a test for genetic resistance in colonized Ae. taeniorhynchus, the mean infection rates +/-SD for groups of randomly selected and sibling larvae were compared. The standard deviation of the sibling groups was not higher than the random groups (4.0 +/- 3.1% and 3.0 +/- 2.1%), rendering genetic resistance unlikely. Injury to the larvae by feeding silicon carbide fibers consistently caused higher infection rates (4.8 +/- 2.0% by virus alone and 17.5 +/- 5.3% by virus and fibers concurrently). Similar results were obtained for vertical transmission. These results support the hypothesis that this virus has no active means of penetration, invading only through random breaks in the cuticle or peritrophic membrane.

Significant mortalities were present at 48 h postfeeding, with probit analysis yielding an LC50 of 0.35 mug/ml and a slope of 4.12. All dosages caused significant decreases (P < 0.01) in egg production and sporadic decreases in egg hatch, with no eggs produced at 1.0 mug/ml. There was a negative linear correlation (r2 = 0.91) between dose rate and number of eggs produced per living female. An inoculation of ivermectin at the recommended dosage of 200 mug/kg of body weight would not produce the serum concentration that could be expected to have noticeable effects on bloodfeeding C variipennis.

Bi-directional Fay and omni-directional traps collected significantly more Ae. albopictus females than did the other traps tested. The bi-directional Fay trap collected significantly more Ae. aegypti females than did any other trap. The results of these studies indicate that these traps may be useful tools for sampling Ae. albopictus and Ae. aegypti adults.

DT Note
AB A device was developed for repetitive sampling of mosquito larvae without undue disruption of the larval habitat. The sampler is a 3-oz. (ca. 100-ml capacity) transparent plastic cup with a hole in the center of its convex bottom. The device is buoyed by corks so that the water level is 15 mm above the bottom rim of the cup and 5 mm above the hole. There was significant correlation between 24-h samples of Aedes albopictus and Culex quinquefasciatus 4th-instar larvae in the larval sampling device and populations in tires. Greater numbers of immature mosquitoes were found per unit surface area of the sampling device than the tire as a whole, demonstrating that immature mosquitoes were trapped by the sampler.

AB A knowledge of the volatile components present in an oil sample can provide important information relative to supercritical fluid extraction (SFE) process design, the current oxidative state of the oil, as well as the concentration and presence of important flavor volatiles in the oil. Volatile compounds from supercritical fluid-extracted oils were analyzed by headspace gas chromatography (GC) methods to determine if there were differences in the volatile profiles when two different methods of desorption were used. Canola, corn, soybean and sunflower seeds were extracted with supercritical carbon dioxide at 8000 psi and 50 degrees C. Tenax porous polymer traps, attached at the exhaust port of the SFE apparatus, were utilized to collect the volatile components during the extractions. The volatile compounds on the Tenax trap were desorbed onto a GC column by both thermal and supercritical fluid techniques. Desorption temperature for the thermal method was 150 degrees C, while conditions for the SFE technique were 50 degrees C and 2000 psi. The lower-boiling volatiles from each oilseed were greater when desorbed by thermal means from the Tenax than by SFE; however, SFE desorbed the higher-molecular weight compounds that were not removed by the thermal desorption method. Hexanal tended to be desorbed in comparable amounts by both methods. The SFE-based desorption technique provides a unique analysis method for the determination of both volatile and semivolatile compounds, as well as executing desorption under nonoxidative, low-temperature conditions that do not contribute to the degradation of lipid components.

Vacuum infiltration of callus with the toxin solution was the only successful selection method at the concentrations tested. Primary callus (callus originating directly from the explant) was not sensitive to roridin A or E at the concentrations used. Secondary callus (callus produced from primary callus) exhibited a differential response to roridins A and E similar to that of detached-leaf assays. Electrolyte leakage studies of callus were not conclusive in establishing the membrane as the site of toxin action or useful for screening tolerance in vitro. A small percentage of callus from tolerant and susceptible cultivars survived repeated exposure to roridin E at 50 mu g.ml(-1).

AB Physical and biological parameters affecting the efficiency of biolistic transformation of peach were optimized using beta-glucuronidase (GUS) as a reporter gene, such that efficiency of transient GUS expression in peach embryo-derived callus was increased markedly. Transient expression was also obtained in embryonic axes, immature embryos, cotyledons, shoot tips, and leaves of peach. Stable expression of a fusion gene combining neomycin phosphotransferase (NPTII) and beta-glucuronidase activities has been achieved in peach embryo calli. Sixty-five kanamycin-resistant callus lines were obtained from 114 pieces of bombarded calli after 4 months of selection. Nineteen of the 65 putative transformant lines produced shoot-like structures. Seven lines were examined to confirm stable transformation using the colorinetric GUS assay and PCR analysis. All seven lines showed GUS activity. PCR analysis confirmed that, in most of the putative transformants, the chimeric GUS/NPTII gene had been incorporated into the peach genome. The transgenic callus lines were very weakly morphogenic, presumably because the callus was 5 years old and no transgenic shoots developed from this callus. Results of this research demonstrate the feasibility of obtaining stable transgenic peach tissue by biolistic transformation.

AB Soybean flakes were extracted with supercritical carbon dioxide to produce a solvent-free, good-quality soybean oil. Volatile compounds from the supercritical fluid extracted (SFE) oil and from a hexane-extracted crude soybean oil were analyzed by dynamic headspace gas chromatographic methods to determine qualitative differences between the extraction methods. The major difference in the-volatile profiles was the higher concentration of hexane in the solvent-extracted oil. During the SFE process, volatile compounds were trapped on a porous polymer trap attached at the exhaust port of the SFE apparatus. The volatile profile obtained from the sorbent trap was found to be similar to the headspace profile from the SFE/soybean oil removed during the same extraction. In addition, crude soybean oil was heated in a stirred reactor and the volatiles, which were stripped by supercritical carbon dioxide in an attempt to improve oil properties, were collected on sorbent traps and analyzed by the above method for comparison. The described methodology permits the characterization of volatiles and semivolatiles in SFE soybean oil and can be used to monitor the extraction and quality of the resultant oil.

AB Cytotoxic T lymphocytes (CTL) can control some viral infections and may be important in the control of lentiviruses, including human immunodeficiency virus type 1. Since there is limited evidence for an in vivo role of CTL in control of lentiviruses, dissection of immune mechanisms in animal lentiviral infections may provide needed information. Horses infected with equine infectious anemia virus (EIAV), a lentivirus, have acute plasma viremia which is terminated in immunocompetent horses. Viremic episodes may recur, but most horses ultimately control infection and become asymptomatic carriers. To begin dissection of the immune mechanisms involved in EIAV control, peripheral blood mononuclear cells (PBMC) from infected horses were evaluated for CTL to EIAV-infected cells. By using noninfected and EIAV-infected autologous equine kidney (EK) cells in Cr-51-release assays, EIAV-specific cytotoxic activity was detected in unstimulated PBMC from three infected horses. The EIAV-specific cytotoxic activity was major histocompatibility complex (MHC) restricted, as determined by assaying EIAV-infected heterologous EK targets, and was mediated by CD8(+) T lymphocytes, as determined by depleting these cells by a panning procedure with an anti-CD8 monoclonal antibody. MHC-restricted CD8(+) CTL in unstimulated PBMC from infected horses caused significant specific lysis of autologous EK cells infected with recombinant vaccinia viruses expressing EIAV genes, either env or gag plus 5' pol. The EIAV-specific MHC-restricted CD8(+) CTL were detected in two EIAV-infected horses within a few days after plasma viremia occurred and were present after viremia was terminated. The detection of these immune effector cells in EIAV-infected horses permits further studies to determine their in vivo role.

AB The Lymantria dispar multinucleocapsid nuclear polyhedrosis virus (LdMNPV) gene encoding vPK has been cloned and sequenced. LdMNPV vPK shows a 24% amino acid identity to the catalytic domains of the eucaryotic protein kinases nPKC from rabbits, HSPKCE from humans, APLPKCB from Aplysia californica, and dPKC98F from Drosophila melanogaster, and homology to several other protein kinases from yeasts, mice, and bovines. The homology suggests that vPK is a serine/threonine protein kinase as defined by Hanks et al. (S. K. Hanks, A. M. Quinn, and T. Hunter, Science 241:42-52, 1988). Temporal expression studies indicate that vPK is expressed throughout the infection cycle beginning at 4 h postinfection, first as a delayed-early gene and subsequently as a late gene. Sequence analysis and primer extension reactions confirm the presence of distinct early and late transcription initiation regions. Expression of vPK with a rabbit reticulocyte system generated a 31-kDa protein, which is in close agreement with the predicted size of 32 kDa from the amino acid sequence. Phosphorylation activity of in vitro-expressed vPK was demonstrated by using calf thymus histones.

AB We previously reported the isolation of a flavonoid-inducible gene from the pSym of Rhizobium fredii strain USDA 201 (Sadowsky et al. 1988). In this study, we report that a Tn5 insertion in this gene results in a 6-day delay in the appearance of nodules and a 70% decrease in the number of nodules relative to nodulation by the wild-type R. fredii USDA 201. We have named this gene nolJ. While the 5' region of nolJ does not contain a highly conserved nod box consensus sequence, RNA dot blot hybridization analyses indicated that the flavonoid induction of nolJ is dependent on a functional nodD1 gene. Our data suggest that transcriptional activation of nolJ occurs by a mechanism different from that proposed for many other nodulation loci.

DE BASIDIOMYCOTINA; CRYOVIAL; CULTURE COLLECTION; WATER STORAGE

AB Prior to 1985, cultures at the Center for Forest Mycology Research were maintained on 1.5% malt extract agar test-tube slants. This system not only made it necessary to transfer the entire collection every year but also permitted genetic change because continual growth occurred. In 1985, the method of storing fungal cultures in sterile distilled water in cryovials was introduced. This study reports on the use of this method for long-term fungal storage. For varying periods up to 7 years, 151 miscellaneous species of wood-decaying Basidiomycotina were stored in sterile distilled water. Water storage has numerous advantages: culture viability or growth rate is not significantly influenced; isolates can be stored longer; genetic stability is greater; the method is quick, easy, and inexpensive, and requires less space.

AB Four agar media used to isolate aflatoxin producing fungi were compared for utility in isolating fungi in the Aspeugillus flavus group from agricultural soils collected in 15 fields and four states in the southern United States. The four media were Aspeugillus flavus and parasiticus Agar (AFPA, 14), the rose bengal agar described by Bell and Crawford (BCRB; 3), a modified rose bengal agar (M-RB), and Czapek's-Dox Agar supplemented with the antibiotics in BC-RB (CZ-RB). M-RB was the most useful for studying the population biology of this group because it permitted both identification of the greatest number of A, flavus group strains and growth of the fewest competing fungi. M-RB supported an average of 12% more A. flavus group colonies than the original rose bengal medium while reducing the number of mucorales colonies and the number of total fungi by 99% and 70%, respectively. M-RB was successfully employed to isolate all three aflatoxin producing species, A. flavus, A. parasiticus and A. nomius, and both the S and L strains of A. flavus. M-RB is a defined medium without complex nitrogen and carbon sources (e.g. peptone and yeast extract) present in BC-RB. M-RB should be useful for studies on the population biology of the A. flavus group.

AB Environmental control plots adjusted to late season drought and elevated soil temperatures were inoculated at peanut planting with low and high levels of conidia, sclerotia, and mycelium from a brown conidial mutant of Aspergillus parasiticus. Percentage infection of peanut seeds from undamaged pods was greatest for the subplot containing the high sclerotial inoculum (15/cm(2) soil surface). Sclerotia did not germinate sporogenically and may have invaded seeds through mycelium. In contrast, the mycelial inoculum (colonized peanut seed particles) released large numbers of conidia into soil. Soil conidial populations of brown A. parasiticus from treatments with conidia and mycelium were positively correlated with the incidence of seed infection in undamaged pods. The ratio of A, flavus to wild-type A. parasiticus in soil shifted from 7:3 to 1:1 in the uninoculated subplot after instigation of drought, whereas in all subplots treated with brown A, parasiticus, the ratio of the two species became approximately 8:2. Despite high levels of brown A, parasiticus populations in soil, native A, flavus often dominated peanut seeds, suggesting that it is a more aggressive species. Sclerotia of wild-type A. parasiticus formed infrequently on preharvest peanut seeds from insect-damaged pods.

Coronal and sagittal frozen sections (30-60 mu m) of Zamboni's fixed hypothalamic tissue, without prior colchicine treatment were incubated with GHRH or SS primary antisera for 48 h, then visualized by peroxidase-diaminobenzidine immunocytochemistry. Fusiform, bipolar SS-ir perikarya were located about the third ventricle in the periventricular nucleus, extending from rostral aspects of preoptic periventricular nucleus to a level approximate with caudal regions of the paraventricular nucleus. Rounded or fusiform, bipolar GHRH-ir perikarya were mostly located in ventrolateral portions of the arcuate nucleus in pigs and cattle, and within ventral aspects of the ventromedial nucleus in pigs but rarely in cattle. In both pigs and cattle, SS-ir and GHRH-ir fibers projected ventrally into the median eminence with dense and overlapping innervation of the external layer, especially dense in lateral regions. In pigs, but not as distinguishable in cattle, SS-ir fibers also densely innervated the ventromedial and arcuate hypothalamic nuclei. Double immunostained sections revealed close apposition of SS-ir fibers and varicosities with GHRH-ir perikarya in arcuate and ventromedial nuclei, and apposition of SS-ir and GHRH-ir varicosities in the median eminence.

AB A three-dimensional model for heat and mass transport in microscale ice lattices of dry snow is formulated consistent with conservation laws and solid-vapor interface constraints. A finite element model that employs continuous mesh deformation is developed, and calculation of the effective diffusion rates in snow, metamorphosing under a temperature gradient, is performed. Results of the research provide basic insight into the movement of heat and water vapor in seasonal snowcovers. Agreement between the numerical results and measured data of effective thermal conductivity is excellent. The enhancement to the water vapor diffusion rate in snow is bracketed in the range of 1.05-2.0 times that of water vapor in dry air.

New developments include the emerging relationship between Helicobacter pylori infection and an increased risk of gastric cancer, and positive results of chemoprevention trials in decreasing gastric cancer risk with the use of beta-carotene and vitamin E supplements. Factors that may enhance risk include consumption of nitrites, nitrates, alcohol, and highly salted, pickled, fermented or smoked foods. Other environmental factors which may promote cancer are H. pylori infection, inappropriate food storage, metal and cement dust exposure, and cigarette smoking. High intakes of fruits and vegetables or of antioxidants, such as beta-carotene, vitamin E, and vitamin C may decrease risk.

AB Effects of various single and two species diets on the performance of gypsy moth (Lymantria dispar (L.)) were studied when this insect was reared from hatch to pupation on intact host trees in the field. The tree species used for this study were red oak (Quercus rubra L.), white oak (Q. alba L.), bigtooth aspen (Populus grandidentata Michaux), and trembling aspen (P. tremuloides Michaux). These are commonly available host trees in the Lake States region. The study spanned two years and was performed at two different field sites in central Michigan. Conclusions drawn from this study include: (1) Large differences in gypsy moth growth and survival can occur even among diet sequences composed of favorable host species. (2) Larvae that spent their first two weeks feeding on red oak performed better during this time period than larvae on all other host species in terms of mean weight, mean relative growth rate (RGR), and mean level of larval development, while larvae on a first host of bigtooth aspen were ranked lowest in terms of mean weight, RGR, and level of larval development. (3) Combination diets do not seem to be inherently better or worse than diets composed of only a single species; rather, insect performance was affected by the types of host species eaten and the time during larval development that these host species were consumed instead of whether larvae ate single species diets or mixed species diets. (4) In diets composed of two host species, measures of gypsy moth performance are affected to different extents in the latter part of the season by the two different hosts; larval weights and development rates show continued effects of the first host fed upon while RGRs, mortality, and pupal weights are affected strongly by the second host type eaten. (5) Of the diets investigated in this study, early feeding on red oak followed by later feeding on an aspen, particularly trembling aspen, is most beneficial to insects in terms of attaining high levels of performance throughout their lives.

AB A large proportion of gypsy moths (Lymantria dispar (L.)) are likely to experience multiple species diets in the field due to natural wandering and host switching which occurs with these insects. Nutritional indices in fourth and fifth instar gypsy moth larvae were studied in the field for insects that were switched to a second host species when they were fourth instars. The tree species used as hosts were northern pin oak (Quercus ellipsoidalis E. J. Hill), white oak (Q. alba L.), big-tooth aspen (Populus grandidentata Michx.), and trembling aspen (P. tremuloides Michx.). Conclusions of this study include: 1) Insects which fed before the host switch on northern pin oak performed better after the host switch than did insects with other types of early dietary experience. While the northern pin oak-started insects had very low relative food consumption rates on their second host species immediately after the switch, one instar later they had the highest ranked consumption rates. During both instars they had the second highest efficiencies of converting ingested and digested food to body mass. High food consumption rates and relatively high efficiency of food conversion helped these insects to obtain the highest ranked mean relative growth rates in the fifth instar compared to the relative growth rates obtained by insects from any of the other first host species. 2) Among the four host species examined, a second host of trembling aspen was most advantageous for the insects. Feeding on this species after the switch led to higher larval weights and higher relative growth rates for insects than did any of the other second host species. The insects on trembling aspen attained excellent growth despite only mediocre to low food conversion efficiencies. The low efficiencies were offset by high relative food consumption rates. 3) Low food consumption rates often tend to be paired with high efficiency of conversion and vice versa. 4) There is no discernable tendency for the first plant species eaten to cause long-term inductions which affect the ability of gypsy moths to utilize subsequent host plants. Insects did not tend to consume more, grow faster, or be more efficient if their second host plant was either the same as their rearing plant or congeneric to it. Methods are delineated which allow values of nutritional indices to be obtained for insects on intact host plants under field conditions. These methods are useful for the purpose of answering questions about the relative effects that different diet treatments have on insect response.

AB Associations between dental status and skeletal bone density were investigated in a group of 329 healthy postmenopausal women with normal bone density.  Bone mineral density (BMD) of the lumbar spine, femoral neck and distal radius were measured by dual- or single-photon absorptiometry.  Number of teeth remaining were counted and presence of complete dentures noted by a nurse practitioner.  Forty-eight women (15%) wore a complete maxillary and/or mandibular denture:  22 (7%) were completely edentulous and an additional 26 (8%) had one edentulous ridge.  Among women without complete dentures (n = 281), signification positive linear relationships were observed between number of teeth and BMD at the spine (p < 0.05) and radius (p < 0.01), controlling for years since menopause, pack-years of smoking, education and body mass index.  BMD did not differ between the groups with and without dentures.  However, women who acquired dentures after the age of 40 years had significantly lower mean spinal and radial BMD than women who acquired dentures at age 40 years or earlier (at the radius, 0.584 +/- 0.015 v 0.630 +/- 0.017 g/cm2, p < 0.05; at the spine, 1.043 +/- 0.031 v 1.124 +/- 0.029 g/cm2, p = 0.05).  In linear regression analysis, significant independent correlations were found among all women (n = 329) between number of teeth and age (partial r = -0.19, p < 0.001), pack-years of cigarette use (partial r = -0.23, p < 0.001) and years of education (partial r = + 0.11, p < 0.05).  These associations between dental status and BMD support the hypothesis that systemic bone loss may contribute to tooth loss.

AB We have determined the sequence of the phytochrome A gene (PHYA) and its flanking DNA from Arabidopsis thaliana and have identified transcription start sites for three nested transcripts of increasing length. The overall structure of the gene is similar as regards exon/intron organization to other angiosperm PHY genes characterized. The triple transcription start site arrangement is similar to that of pea PHYA but different from the single start site of oat, rice and maize PHYA genes, indicating a possible monocot-dicot difference. Comparison of the Arabidopsis PHYA promoter sequence with others available indicates that both pea and Arabidopsis promoters contain a DNA element with a core sequence motif identical to one conserved in all existing monocot PHYA sequences and defined by functional assay in the oat PHYA gene as repressor element, RE1, responsible for negative light regulation.

AB The National Agricultural Statistics Service (NASS) has been developing area sampling frames as a vehicle for conducting surveys to gather a variety of agricultural data nationwide. In 1987, NASS was awarded a National Aeronautics and Space Administration research grant to develop a digitally based system to automate this process which had been conducted using a labor-intensive, paper-based technique. This system, the Computer Aided Stratification and Sampling (CASS) system, was developed by NASS and the Ames Research Center Ecosystem Technology Branch, and has now been implemented into NASS' operational program. This paper discusses and compares the manual procedure and the new methodology and the results of this research effort.

SO PHOTOGRAMMETRIC ENGINEERING AND REMOTE SENSING
LA English
DT Article
ID GENERAL-CIRCULATION MODEL; RADIATION; SURFACE
AB Satellite data have provided considerable information on the radiation budget at the top of the Earth-atmosphere system. However, in order to maximize the usefulness of these observations, it is necessary to know how the radiative heating and cooling are distributed within the atmosphere and between the Earth's surface and the atmosphere. A technique has been developed to use radiance data from the High Resolution Infrared Sounder (HIRS) instrument flown on NOAA operational satellites to obtain estimates of the profile of longwave atmospheric cooling (LC) and the atmospheric emission to the Earth's surface (downward longwave radiation, DLR). Briefly, the DLR and LC are estimated from HIRS radiance observations using regression techniques on radiative transfer calculations. The technique requires the spectral radiance data from HIRS and the vertical distribution of cloud amount and cloud-base and cloud-top heights. Cloud information is not generally available concomitantly with the HIRS radiances, and the initial effort has focused on the development of clear sky models. Radiative cooling is calculated for four layers: surface to 700 mb, 700 to 500 mb, 500 to 240 mb, and 240 to 10 mb.
   Initially, a month-long data set was produced - 15 December 1990 through 15 January 1991 - for study and technique evaluation. Calculations were global on a 2.5-degrees by 2.5-degrees latitude-longitude grid. Monthly averages and five-day running means were produced. Comparisons were made to the National Meteorological Center (NMC) medium range forecast (MRF) model fields of LC and DLR. The agreement was generally within values expected from comparisons of calculations from the different models, especially for zonally averaged quantities. There were, however, significant differences over specific geographical areas (e.g., Africa and Australia). Analysis of these differences indicated where improvements were needed in the HIRs and the MRF techniques, resulting in an improved HIRs model for estimating clear sky DLR and LC.
   The clear-sky algorithms for the LC and outgoing longwave radiation at the top of the atmosphere have been implemented as an experimental quasi-operational system for further evaluation. Twelve months of data (June 1992 through May 1993) have been processed to date, and the availability of the data were announced to the international climate community for use and evaluation beginning in January 1993.

AB The excision of the root system from 6-day-old sunflower (Helianthus annuus L. cv. Dahlgren 131) results in the initiation and formation of adventitious root primordia, a wound response, and the formation of primary phloem fibers in the 1-cm portion of the hypocotyl above the cut surface. We have investigated the alteration of gene expression at the level of protein synthesis and transcript abundance associated with the early events occurring in the hypocotyls following root excision. Comparisons were made to the proteins synthesized in vivo from hypocotyls of seedlings from which both the root system and cotyledons had been removed. Loss of both structures reduces adventitious root formation and phloem fiber deposition. A total of 60 proteins was identified as exhibiting a definite response to derooting, 50 of which are novel. Of these 50 novel proteins a subset of seven proteins can be tentatively ascribed to the processes of adventitious root formation and phloem fiber deposition. The remainder of the 50 novel proteins and the 10 proteins, the synthesis of which is elevated upon the excision of roots, are more likely to be involved in the wounding response. Analysis of transcript pools by in-vitro-protein synthesis from extracted poly (A+) RNA demonstrates that at least part of the response results in a qualitative change in the pool of translatable RNAs. However, not all of the observed alterations in protein synthesis can be explained in this way. It is likely that changes in the transcript pools occur in localized actively changing cells and are masked in the overall hypocotyl RNA pool. Such a dilution effect does not affect the protein synthesis patterns.

AB A growth analysis was made of ultraviolet-B (UV-B)-sensitive (Poinsett) and insensitive (Ashley) cultivars of Cucumis sativus L. grown in growth chambers at 600 mumol m-2 s-1 of photosynthetic photon flux (PPF) provided by red- and far-red-deficient metal halide (MH) or blue- and UV-A-deficient high pressure sodium/deluxe (HPS/DX) lamps. Plants were irradiated 6 h daily with 0.2 (-UV-B) or 18.2 (+UV-B) kJ m-2 day-1 of biologically effective UV-B for 8 or 15 days from time of seeding. In general, plants given supplemental UV-B for 15 days showed lower leaf area ratio (LAR), and higher specific leaf mass (SLM), mean relative growth rate (MRGR) and net assimilation rate (NAR) than that of control plants, but they showed no difference in leaf mass ratio (LMR). Plants grown under HPS/DX lamps vs MH lamps showed higher SLM and NAR, lower LAR and LMR, but no difference in MRGR. LMR was the only growth parameter affected by cultivar; at 15 days, it was slightly greater in Poinsett than in Ashley. There were no interactive effects of UV-B, PPF source or cultivar on any of the growth parameters determined, indicating that the choice of either HPS/DX or MH lamps should not affect growth response to UV-B radiation. This was true even though leaves of UV-B-irradiated plants grown under HPS/DX lamps have been shown to have greater chlorosis than those grown under MH lamps.

AB Sterols were identified and quantified in six marine microalgal strains identified as belonging to the prymnesiophyte genus Isochrysis; several of these strains are in wide use in the commerical mariculture industry. One strain contained only cholesterol, and another contained a complex mixture of Delta(5)-sterols and dihydroxysterols. Two strains contained brassicasterol and two others contained epibrassicasterol as the principal sterol. The strains containing brassicasterol or epibrassicasterol also contained long chain alkenones characteristic of some members of the Prymnesiophyceae; whereas, those without brassicasterol or epibrassicasterol contained no long chain alkenones. These qualitative biochemical differences appear to have taxonomic significance and may be important in the value of these algae as live feeds for rearing marine invertebrates.

AB Specific race interactions between Colletotrichum trifolii and cultivars of resistant and susceptible alfalfa were examined in nonwounded excised cotyledons.  Cotyledons in incompatible and compatible interactions exhibited visible differential reactions within 7-10 days after inoculation.  C. trifolii infected alfalfa by directly penetrating the epidermis via a penetration peg from the appressorium.  Appressoria matured within 20 h on resistant and susceptible cotyledons, but primary hyphae did not develop on resistant cotyledons.  Phenylalanine ammonia-lyase and the pterocarpan phytoalexin medicarpin began to increase in resistant tissues after 24 h.  Cotyledon tissues apparently became resistant prior to significant increases in medicarpin.  Medicarpin concentration in resistant cultivars was highest at 72 h and declined to baseline levels by 120 h.  Secondary spores were produced in susceptible tissues after 96 h.  Cotyledons appear to be ideal tissues to use in investigations of defense expression in the anthracnose disease of alfalfa.

AB Galls on 10-mo- to 2-yr-old slash and loblolly pine seedlings inoculated with Cronartium quercuum f. sp. fusiforme were compared with healthy stems by magnetic resonance microscopy (MRM).  After transpiration, high-resolution images (35-58 mum) of excised stem segments were acquired.  MRM images showed a greater signal in the xylem of healthy stems than in galls, suggesting differing wood/water interactions.  In 10-mo-old galled seedlings, the cambium and phloem were contiguous between healthy and galled regions.  Water-transport disruption occurred in the xylem at the interface between galled and healthy regions, but in the center of the galls, secondary xylem appeared water-filled.  At 2 yr of age, water transport was observed throughout the secondary xylem of a healthy stem but was completely impeded through the gall of a declining seedling.  In contrast, a bright ring of conductive secondary xylem surrounded a dark, nonconductive center in the gall of a vigorous, 2-yr-old seedling.  This study shows changes in anatomy and functional physiology in vivo with respect to water relations in fusiform rust galls on pine that are detectable by MRM.

AB Biological activity of chitosan on Pythium rot of cucumber was investigated.  Growing cucumber plants in the presence of chitosan (100 or 400 mug/ml) controlled root rot caused by Pythium aphanidermatum and triggered several host defense responses, including the induction of structural barriers in root tissues and the stimulation of antifungal hydrolases (chitinase, chitosanase, and beta-1,3-glucanase) in both the roots and leaves.  Whereas chitosan did not cause any apparent phytotoxicity to cucumber plants, it adversely affected the growth of P. aphanidermatum.  A close examination of hyphal cells revealed that chitosan caused wall loosening, vacuolation, and, in some cases, protoplasm disintegration.  This may, in part, explain the limited ability of the pathogen to colonize root tissues in the presence of chitosan.  Ultrastructural study of root tissue from chitosan-treated plants showed that fungal cells were mainly restricted to root surfaces.  The interplay of the antifungal and eliciting properties of chitosan makes chitosan a potential antifungal agent for the control of root rot of cucumber caused by P. aphanidermatum.

DT Article
DE BETA-VULGARIS; STORAGE LOSSES; ROOT YIELD; SUGAR CONCENTRATION
AB Respiration is responsible for much of the sucrose loss that occurs during sugarbeet (Beta vulgaris L.) storage. Genotypes with reduced storage respiration rates would provide an efficient method for reducing sucrose losses. However, the current techniques for measuring storage respiration are not adapted easily to breeding programs. Internal CO2 concentration has been recommended as an efficient method for measuring the respiration rate of individual sugarbeet roots in storage. This study examined the effectiveness of internal CO2 concentration as a selection criterion for reducing respiration rate of sugarbeet during storage. Lines resulting from four cycles of divergent selection for internal CO2 concentration were evaluated along with commercial hybrids and low internal CO2 germplasm lines. Selection was effective in shifting internal CO2 concentration. Relative differences in internal CO2 concentration were consistent throughout the 3-year study. Neither the fourth-cycle selections for low nor the fourth-cycle selections for high internal CO2 concentration were significantly different from the original population for evolved CO2. This lack of a close relationship between internal and evolved CO2 indicated that internal CO2 concentration is not an effective selection criterion in a breeding program.

AB Genetic information is needed on maysin, a compound in maize, Zea mays L., silks that is antibiotic to corn earworm larvae, Helicoverpa (formerly Heliothis) zea (Boddie), to assist in the process of breeding for resistance to this pest. This study was initiated to elucidate the inheritance of maysin content in the silks of a cross between two maize inbreds (GT114 and GT119) having resistance to the com earworm. Reversed phase high performance liquid chromatography (HPLC) procedures were used to quantify the maysin concentration of silks from individual plants in the parent, F1, F2, and first backcross generations of the cross GT114 x GT119. A model assuming dominance at a single locus for low maysin content which is expressed only when a dominant modifier is present was proposed to explain the segregation ratios obtained in the F1 and first backcrosses of GT114 x GT119. This model also provided a fit for maysin data previously generated from a cross between inbreds F6 and F44. Observations of selfed families in the backcross of GT114 x GT119 to the low maysin parent confirmed the two-locus model (one factor with dominance for low maysin expressed only when a modifier gene is also present) as a plausible explanation for inheritance of silk maysin in the cross. The process of selection for high maysin will be complicated somewhat by the presence of a gene which modifies the expression of dominance unless a method of easily identifying the gene, independent of maysin content, can be developed.

AB We used the exaggerated short hypocotyl phenotype induced by oat phytochrome A overexpression in transgenic Arabidopsis to monitor the biological activity of mutant phytochrome A derivatives. Three different mutations, which were generated by removing 52 amino acids from the N terminus (DELTAN52), the entire C-terminal domain (DELTAC617), or amino acids 617-686 (DELTA617-686) of the oat molecule, each caused striking dominant negative interference with the ability of endogenous Arabidopsis phytochrome A to inhibit hypocotyl growth in continuous far-red light (''far-red high irradiance response'' conditions). By contrast, in continuous white or red light, DELTAN52 was as active as the unmutagenized oat phytochrome A protein in suppressing hypocotyl elongation, while DELTAC617 and DELTA617-686 continued to exhibit dominant negative behavior under these conditions. These data suggest that at least three spatially discrete molecular domains coordinate the photoregulatory activities of phytochrome A in Arabidopsis seedlings. The first is the chromophore-bearing N-terminal domain between residues 53 and 616 that is apparently sufficient for the light-induced initiation but not the completion of productive interactions with transduction chain components. The second is the C-terminal domain between residues 617 and 1129 that is apparently necessary for completion of productive interactions under all irradiation conditions. The third is the N-terminal 52 amino acids that are apparently necessary for completion of productive interactions only under far-red high irradiance conditions and are completely dispensable under white and red light regimes.

AB The spatial distribution of a plant species is limited by the range of climatic conditions to which the species can adapt. Temperature is one of the most significant determinants of plant distribution, but except for the effects of lethal limits, little is known about physiological changes in responses to differences in environmental temperature. In this study, temperature coefficients of non-photosynthetic metabolism have been determined in the normal environmental temperature range for selected annual and perennial plants. Distinct differences were found in the temperature coefficient of metabolism of woody perennial plants from high latitudes and high elevations and closely related low-latitude and low-elevation plants. Low-latitude and low-elevation woody perennials have Arrhenius temperature coefficients for metabolism that are larger than those for congeneric high-latitude and high-elevation plants. The Arrhenius temperature coefficient is not rapidly adapted to new environments. A simple function was developed relating Arrhenius temperature coefficient to latitude and elevation for accessions of three, woody, perennial species complexes of plants collected from a wide geographic range but grown in common gardens. Within these taxa, plants that experience broader ranges of temperature during growth in their native habitat have smaller temperature coefficients. Temperature coefficients also varied with growth stage or season. No similar relationship was found for annuals and herbaceous perennials. For the plants tested, Arrhenius temperature coefficients are high during early spring growth, but shift to lower values later in the season. The shift in Arrhenius temperature coefficients occurs early in the season for southern and low-elevation plants and progressively later for plants from further north or higher elevation. The changes in Arrhenius temperature coefficients result largely from increases in plant metabolic rates at lower temperatures while Little change occurs in the rates at higher temperatures. Altering the temperature dependence of the control of metabolic rate is apparently an important means of response to climate change.

AB The MARYBLYT computer model was evaluated for its accuracy in forecasting apple blossom infection by Erwinia amylovora and the subsequent appearance of fire blight symptoms. Temperature and rainfall data were collected and disease observations recorded in bearing orchards in West Virginia and Maryland during 1984 1993. Among the 13 primary infection events identified by the model at all sites in eight of the 10 yr, blossom blight symptoms appeared 10 times within +/- 1 day, twice within 2 days, and only once within 3 days of the MARYBLYT prediction. Only three times in 10 yr did MARYBLYT predict blossom infection without symptom development. In no instance did spurious symptoms appear that would indicate the model failed to identify an infection period. A blossom sampling procedure conducted during 5 yr (1985, 1987, 1988, 1990, and 1993) in which blossom blight occurred confirmed the presence of E. amylovora coincident with the model's threshold calculation of epiphytic infection potential. When blossoms were inoculated artificially by introducing a bacterial suspension (10(8) cfu/ml) into flower nectaries, blossom blight symptoms developed 0, 1-3, and >5 days prior to that predicted by the model in one, seven, and three trials, respectively. In 11 trials, an average of 57 degree days >12.7 C was accumulated between artificial inoculations and symptom appearance, which is consistent with the model's algorithm for symptom occurrence. The results of our field evaluations of MARYBLYT for predicting blossom infection and subsequent symptom development show that the model is accurate. Treatment decisions based on MARYBLYT can be expected to improve the level of control of this destructive disease.

ID REGISTRATION; RESISTANCE
AB Stem rust caused by Puccinia graminis subsp. graminicola was controlled by propiconazole in perennial ryegrass (Lolium perenne) grown for seed. Between 1986 and 1992, the fungicide was applied up to six times per year to plants in different stages of growth. A two-application treatment (126 a.i./ha) was effective for increasing seed yield and controlling stem rust, with the first application when spikes began to emerge from the boot and the second when spikes were fully emerged. Stem rust was first observed as early as 29 April and as late as 16 July. Seed yields were smaller when stem rust epidemics began in early spring. A threefold to 10-fold increase in seed yield was observed among cultivars treated with propiconazole compared with nontreated controls. Regardless of treatment, cultivars Birdie II and Linn produced greater seed yields than Palmer, Delray, Yorktown II, and Ovation. Significant differences occurred in thousand seed weight and biomass dry weight (seeds and straw) between fungicide treatments and among cultivars.

AB The microbiota from 29 different agricultural soils were individually transferred to separate samples of gamma irradiation-sterilized field soil enriched with potato periderm. After incubation, the samples (chemically, physically, and nutritionally similar but microbiologically dissimilar) were assayed for biological suppressiveness to Fusarium dry rot using a whole-tuber/infested-soil assay. Over 350 isolates of bacteria, yeasts, and actinomycetes were recovered from tubers and soil associated with the five most suppressive soil samples. In three of four soils assayed, periderm amendment increased suppressiveness over that in the same soil without the amendment. In a whole-tuber assay, 18 bacterial strains consistently suppressed dry rot incited by three different strains of Gibberella pulicaris, including one resistant to thiabendazole. Strains effective in biological control included members of the genera Pseudomonas, Enterobacter, and Pantoea. The time of isolation after initiating the whole-tuber/ infested-soil assay and the isolation medium influenced the number of effective strains recovered. The majority of the 18 superior biological control strains were recovered from two of the five suppressive soil samples.

AB Fusarium moniliforme, mating population A, causes various disease symptoms and produces several mycotoxins on com. This fungus is one of the causal agents of seedling blight of corn. A test was designed to determine the pathogenicity of F. moniliforme isolates and to test for resistance in corn against this pathogen. The test is conducted conveniently under laboratory conditions. After a 21-day period, either a fungal isolate or a corn cultivar can be tested for pathogenicity or seedling resistance, respectively. The results, obtained from a limited number of corn cultivars, established that there is resistance to the fungus at the seedling stage. Inbreds were more resistant than parental types used in the initial crosses. The data did not suggest a tendency towards physiological specialization within a selected group of isolates from mating population A.

AB Cereal rust trap plots were planted along a 2,687-km route using interstate and federal highways in the southeastern United States. The technique was developed and evaluated to study the oversummering and overwintering biology of four major cereal rusts: leaf and stem rusts of wheat, and crown and stem rusts   of oats. The interstate highway system was selected to provide ease and speed of access for planting and monitoring, and for general safety reasons. Markers placed at 20-ml (32-km) intervals were selected for the trap plot sites to conform to established cereal rust survey techniques. Susceptible, well-adapted cultivars were preplanted in the green-house for subsequent transplanting at the sites and/or seeded directly to increase the likelihood of plot survival. The trials were conducted over a 7-yr period, 1986-1993, with 3 yr used to study oversummering (planted in July and sampled in November) and 4 yr to study overwintering biology during the normal growing season (planted in November and sampled in April). Severe droughts limited survival in 1986 and 1987. In 1988, several plots along the Gulf Coast were flooded and died. Planting and culturing techniques were modified each year to improve survival. Oversummering data indicated this method is useful for monitoring cereal rust survival during the summer, but plot survival rates under extreme stress may limit the effectiveness of the technique. Trials during 1990-1993 were promising, supplying both incidence and virulence data to supplement USDA-ARS Cereal Rust Laboratory annual surveys.

AB The gene encoding Arabidopsis thaliana aspartate kinase (ATP:L-aspartate 4-phosphotransferase, EC 2.7.2.4) was isolated from genomic DNA libraries using the carrot ak-hsdh gene as the hybridizing probe. Two genomic libraries from different A. thaliana races were screened independently with the ak probe and the hsdh probe. Nucleotide sequences of the A, thaliana overlapping clones were determined and encompassed 2 kb upstream of the coding region and 300 bp downstream. The corresponding cDNA was isolated from a cDNA library made from poly(A)(+)-mRNA extracted from cell suspension cultures. Sequence comparison between the Arabidopsis gene product and an AK-HSDH bifunctional enzyme from carrot and from the Escherichia coli thrA and metL genes shows 80%, 37.5% and 31.4% amino acid sequence identity, respectively. The A. thaliana ak-hsdh gene is proposed to be the plant thrA homologue coding for the AK isozyme feedback inhibited by threonine. The gene is present in A, thaliana in single copy and functional as evidenced by hybridization analyses.
   The apoprotein-coding region is interrupted by 15 introns ranging from 78 to 134 bp. An upstream chloroplast-targeting sequence with low sequence similarity with the carrot transit peptide was identified. A signal sequence is proposed starting from a functional ATG initiation codon to the first exon of the apoprotein. Two additional introns were identified: one in the 5' non-coding leader sequence and the other in the putative chloroplast targeting sequence. 5' sequence analysis revealed the presence of several possible promoter elements as well as conserved regulatory motifs. Among these, an Opaque2 and a yeast GCN4-like recognition element might be relevant for such a gene coding for an enzyme limiting the carbon-flux entry to the biosynthesis of several essential amino acids. 3' sequence analysis showed the occurrence of two polyadenylation signals upstream of the polyadenylation site.
   This work is the first report of the molecular cloning of a plant ak-hsdh genomic sequence. It describes a promoter element that may bring new insights to the regulation of the biosynthesis of the aspartate family of amino acids.

AB Mineral uptake by soybean (Glycine max [L.] Merrill) seeds during development can significantly affect seed quality and value. Little is known about seed mineral transport mechanisms and control processes, although it is clear that each mineral displays a characteristic accumulation pattern. ion-specific accumulation patterns could result from changes in source availability, in transport kinetics through the seed pod and seed coat, or in the mineral uptake capability of the embryo. Ca2+ and K+ have negligible and high phloem mobilities, respectively. Ca2+ accumulation lags behind dry matter (C and N) and K+ accumulation in soybean embryos. To eliminate source availability influences, the Ca2+ and K+ uptake ability of isolated embryos and of seeds in pod culture was examined during seed development. Sr2+ and Rb+ were used as transport analogs of Ca2+ and K+, respectively. Sr2+ and Rb+ uptake rates by isolated embryos increased with seed fresh weight, indicating that the embryo was not limiting Ca2+ accumulation. However, the pod-cultured embryo Sr2+ and Rb+ uptake rate trends differed: Rb+ uptake increased with seed fresh weight, whereas Sr2+ uptake rates remained constant or decreased slightly. Ovule Sr2+ influx data suggest that the pod and seed coat impose a transport barrier that could account for the relative decline in embryo Ca2+ content during development.

AB The effects of Fe deficiency on the extracellular Fe3+ reduction by citrus seedling roots were characterized relative to the ability of citrus to acquire Fe in nutrient solutions. The roots of Fe-deficiency-stress resistant rootstocks, when grown in minus-Fe solutions, have sharply increased rates of Fe3+ reduction and uptake compared to plants grown in complete nutrient solutions. The levels of stimulation in the resistant rootstocks are much higher than those that occur in susceptible rootstocks. There was a correspondingly greater increase in Fe uptake by the Fe deficiency resistant rootstocks than in Fe deficient, susceptible rootstocks. Strong inhibition of Fe uptake by bathophenanthrolinedisulfonic acid indicated that Fe3+ reduction is essential for the Fe uptake by citrus. These findings indicate that degrees of Fe-deficiency-stress resistance in citrus rootstocks are determined by the levels of stimulation of root-associated Fe3+ reduction.

AB Although carbon 13 nuclear magnetic resonance spectroscopy (C-13-NMR) is widely used in lignin structural studies, serious difficulties are encountered in the assignments of C-13 signals because of their extensive overlaps resulting from the complex structure of lignin and of delicate detection of minor structures. To overcome these difficulties, specifically C-13-enriched precursors of lignin biosynthesis, coniferin-[side chain-beta-C-13] and coniferin-[side chain-gamma-C-13], were administered to growing stems of ginkgo (Ginkgo biloba). The NMR analysis of the milled wood lignins isolated from the newly formed xylem showed that selective enrichment of specific carbons of protolignin in the cell wall was achieved without seriously disturbing the lignin biosynthesis. The presence of saturated methylene side chains in the protolignin was shown for the first time by this selective enrichment technique in combination with NMR analysis.

AB Certain higher plants synthesize and accumulate glycine betaine, a compound with osmoprotectant properties. Biosynthesis of glycine betaine proceeds via the pathway choline --> betaine aldehyde --> glycine betaine. Plants such as tobacco (Nicotiana tabacum L.) which do not accumulate glycine betaine lack the enzymes catalyzing both reactions. As a step towards engineering glycine betaine accumulation into a non-accumulator, spinach and sugar beet complementary-DNA sequences encoding the second enzyme of glycine-betaine synthesis (betaine aldehyde dehydrogenase, BADH, EC 1.2.1.8) were expressed in tobacco. Despite the absence of a typical transit peptide, BADH was targeted to the chloroplast in leaves of transgenic plants. Levels of extractable BADH were comparable to those in spinach and sugar beet, and the molecular weight, isoenzyme profile and K(m) for betaine aldehyde of the BADH enzymes from transgenic plants were the same as for native spinach or sugar beet BADH. Transgenic plants converted supplied betaine aldehyde to glycine betaine at high rates, demonstrating that they were able to transport betaine aldehyde across both the plasma membrane and the chloroplast envelope. The glycine betaine produced in this way was not further metabolized and reached concentrations similar to those in plants which accumulate glycine betaine naturally. Betaine aldehyde was toxic to non-transformed tobacco tissues whereas transgenic tissues were resistant due to detoxification of betaine aldehyde to glycine betaine. Betaine aldehyded ehydrogenase is therefore of interest as a potential selectable marker, as well as in the metabolic engineering of osmoprotectant biosynthesis.

AB Mucosal competitive exclusion flora (MCE) and length of MCE culture storage were studied to determine their influence upon colonization of Campylobacter jejuni in chickens. Day-of-hatch broiler chicks, held in isolation units, were treated with MCE or were left untreated. Thirty to 48 h later, groups of chicks were challenged with serial dilutions of C. jejuni (Strain A74/C). Single challenge doses and treatments were administered to chickens within each isolation unit. After 5 d, chicks were killed and levels of the organism in cecal materials were enumerated. Effective MCE was held at -80 C in 15% glycerol for 3 to 9 mo, and efficacy in inhibiting C. jejuni colonization of fresh and stored MCE cultures was compared. Colonization dose-50% (CD50%; dose needed to colonize one-half of the challenged chicks) and colonization quotients (CQ; log10 colony-forming unit geometric means per gram cecal materials) were determined. Data indicated that in three of five trials a significant reduction (P < .02) in CQ was observed in groups of chicks provided fresh MCE as compared with the control groups. Generally, efficacy of MCE treatment decreased with storage of the cultures. This study defines methods for production of MCE and the advantages and limitations of MCE intervention for C. jejuni colonization in chickens.

AB The effects of feeding 2 mg ochratoxin A (OA) and 6 mg 4,15-diacetoxyscirpenol (DAS)/kg of diet singly and in combination were characterized in male broiler chicks from 1 to 19 d of age. Body weights were depressed by OA, DAS, and the OA-DAS combination. There was a significant antagonistic interaction between OA and DAS for uric acid and cholesterol. The efficiency of feed utilization was reduced by DAS alone and by the OA-DAS combination. When compared with controls, additive toxicity was exhibited for reduced efficiency of feed utilization, increased relative weights of the liver and gizzard, and decreased concentration of serum total protein, mean corpuscular volume, and mean corpuscular hemoglobin. All chicks were scored for oral lesions using a scale of 1 to 4 (0 = no visible lesions; 3 = severe lesions). Oral lesions (average score = 2.6) were present in over 90% of the chicks receiving the DAS diet with or without OA. These data demonstrate that both OA and DAS alone and the OA-DAS combination can adversely affect broiler performance and health.

AB Comparative differences between tibial dyschondroplastic (TD) and age-matched control turkey epiphyseal cartilages were studied using cellular, metabolic, and extracellular matrix characteristics. Alkaline phosphatase and aryl sulfatase activities were measured as variables of calcification and cartilage degradation, respectively. There was a decrease in the activities of both enzymes in TD tissues. An increase in tissue phosphate concentrations was noted in the TD tissue whereas neither tissue calcium nor serum calcium and phosphorus concentrations were affected. Profiles of noncollagenous and collagenous proteins from normal and TD-affected tissues were compared following in vitro biotinylation of epiphyseal cartilage followed by a sequential extraction using 4 M guanidine HCI and pepsin digestion, respectively. Electrophoretically separated proteins from both extracts were analyzed on Western blots and compared for any prominent differences between normal and TD cartilages. Biotinylation enhanced the detectibility of extracted proteins. There were, however, no major differences in the patterns of noncollagenous or collagenous proteins between the two groups of tissues. Tibial dyschondroplastic lesions further exhibited a large number of dead chondrocytes, which increased with severity of lesion. There appears to be no significant difference in the pattern of extracellular-matrix-associated proteins. However, enzyme and metabolic activities of TD-affected cartilages were significantly reduced, and this may be due to premature death of chondrocytes in the process of development.

AB We report the use of the bacteriophage P1 Cre-lox system for generating conservative site-specific recombination between tobacco chromosomes. Two constructs, one containing a promoterless hygromycin-resistance gene preceded by a lex site (lox-hpt) and the other containing a cauliflower mosaic virus 35S promoter linked to a fox sequence and the cre coding region (35S-lox-cre), were introduced separately into tobacco plants. Crosses between plants harboring either construct produced plants with the two constructs situated on different chromosomes. Plants with recombination events were identified by selecting for hygromycin resistance, a phenotype expressed upon recombination. Molecular analysis showed that these recombination events occurred specifically at the lox sites and resulted in the reciprocal exchange of flanking host DNA. Progenies of these plants showed 67-100% cotransmission of the new transgenes, 35S-lox-hpt and lox-cre, consistent with the preferential cosegregation of translocated chromosomes. These results illustrate that site-specific recombination systems can be useful tools for the large-scale manipulation of eukaryotic chromosomes in vivo.

AB Foot-and-mouth disease virus appears to initiate infection by binding to cells at an Arg-Gly-Asp (RGD) sequence found in the flexible beta G-beta H loop of the viral capsid protein VP1. The role of the RGD sequence in attachment of virus to cells was tested by using synthetic full-length viral RNAs mutated within or near the RGD sequence. Baby hamster kidney (BHK) cells transfected with three different RNAs carrying mutations bordering the RGD sequence produced infectious viruses with wild-type plaque morphology; however, one of these mutant viruses bound to cells less efficiently than wild type. BHK cells transfected with RNAs containing changes within the RGD sequence produced noninfectious particles indistinguishable from wild-type virus in terms of sedimentation coefficient, binding to monoclonal antibodies, and protein composition. These virus-like particles are defined as ads(-) viruses, since they were unable to adsorb to and infect BHK cells. These mutants were defective only in cell binding, since antibody-complexed ads(-) viruses were able to infect Chinese hamster ovary cells expressing an immunoglobulin Fc receptor. These results confirm the essential role of the RGD sequence in binding of foot-and-mouth disease virus to susceptible cells and demonstrate that the natural cellular receptor for the virus serves only to bind virus to the cell.

Although the latter crystallizes readily and produces a variety of crystal forms, only one was found to be suitable for X-ray studies. It is monoclinic (C2, a=92.8 Angstrom, b=128.9 Angstrom, c=78.3 Angstrom, beta=135.8) with two molecules in the asymmetric unit related by a noncrystallographic diad. The prolipase crystals are orthorhombic (P2(1)2(1)2(1), with a=79.8 Angstrom, b=115.2 Angstrom, c=73.0 Angstrom) and also contain a pair of molecules in the asymmetric unit. Initial results of molecular replacement calculations using the refined coordinates of the related lipase from Rhizomucor miehei identified the correct orientations and positions of the protein molecules in the unit cells of crystals of both proenzyme and the mature form.

TI ECONOMIC-DEVELOPMENT IN SOUTHERN BLACK-BELT COUNTIES - HOW DOES IT
   MEASURE UP
SO REVIEW OF BLACK POLITICAL ECONOMY
LA English
DT Article
AB The effects of racial concentration in shaping patterns of development in the rural South during the 1980s is examined focusing on the southern Black Belt (counties in ten southern states).  Black Belt counties gained fewer or lost more manufacturing plants and tended to have more routine manufacturing than non-Black Belt counties during 1980-86.  But racial concentration had little direct effect on either employment or per capita income growth.  Counties with less educated populations (in both groups) had greater growth in per capita income through the influx of low-wage jobs, underscoring the importance of market forces in influencing patterns of development.

LA English
DT Article
AB The Choleski decomposition L(v) of the variance-covariance matrix V = L(v)L(v), can be used for simulation of genetic values for a population of animals with known numerator and dominance relationship matrices, A and D. If the variances of additive and dominance genetic effects are sigma(a)2 and sigma(d)3 and v(a) and v(d) are vectors of order of the number of animals (N) of standard random normal values, then a = L(A)v(a) and d = L(D)v(d) are the vectors of simulated additive and dominance genetic values for the N animals. The calculations to accumulate elements of a or d can be done one random normal value at a time. Simulation of the multiple trait analog can be done similarly by taking advantage of the direct product property of G(tN), the genetic covariance matrix for the t traits and N animals. With traits ordered within animal, L(GtN) = L(A) x L(G) where L(G) is the Choleski decomposition of G, the matrix of genetic covariances among the traits and x is the direct product operator. The pattern of accumulating the genetic values is such that the accumulation can be done sequentially, one vector of order, t, of standard random normal values at a time.

AB Pearl millet synergids from unpollinated pistils at 1.5-2 and 2.5-3 days postmaturity (dpm) were examined using transmission electron microscopy following antimonate fixation to precipitate loosely-bound calcium (Ca). With increasing age of synergids, the gap above filiform apparatus (FA) and the coalesced vacuoles in midchalazal core extended and merged. The FAs became compressed and precipitates along their common wall were dispersed. The matrix material in numerous small chalazal vacuoles changed from dense to flocculent. Precipitates in vacuoles appeared mainly as clumps without or with a halo in the dense matrix and mostly finely distributed in the flocculent matrix. Eventually, vacuoles became free of both matrix and precipitates. Precipitates bound to nucleus, nucleolus, and micropylar cytoplasm increased initially, but then seemed to decrease, while the nucleus became disorganized and the nucleolus disappeared. Precipitates in the embryo sac wall and nucellar cells also increased initially, but then decreased. At very late stages, egg apparatus and ES lost structural integrity and lacked precipitates. Differences in degeneration and Ca levels of sister synergids were smaller at 1.5-2 dpm than at 2.5-3 dpm. A logical and correlative scheme of degenerative events and Ca distributional changes occurring in pearl millet synergids from maturity to 2.5-3 dpm is presented. The significance of results in pollen tube/sperm cell interactions with synergids and Ca is addressed.

TI STEADY-STATE INFILTRATION AS A FUNCTION OF MEASUREMENT SCALE
SO SOIL SCIENCE
LA English
DT Article
ID SATURATED HYDRAULIC CONDUCTIVITY; SPATIAL VARIABILITY; FIELD
AB Steady-state infiltration rates were measured at three instrument scales within a 4.0 x 4.0-m field plot. The three scales were 4.0 x 4.0 m (scale S(L), n = 1), 1.0 x 1.0 m (scale S(L/4), n = 16), and 0.25 x 0.25 m (wale S(L/16), n = 256). After a 30-day ponding period under a constant hydraulic head, infiltration measurements were made at each measurement scale. Even though the entire area was sampled at each instrument scale, the average infiltration rate decreased with decreasing size of infiltrometer. The infiltration rate measurements were adjusted assuming an ''apparent'' stagnation zone of 4 cm along the boundaries of each infiltrometer. This adjustment produced average infiltration rates of 1.96 cm/h for each of the smaller measurement scales. This value was in excellent agreement with the final value measured at scale S(L) upon completion of the experiment (1.97 cm/h). However, the value for the 'apparent' stagnation zone was found to be valid only in an average sense, because the correlation between the adjusted average value of the S(L/16) measurements and the adjusted value of the S(L/4) measurements was not significant. The 256 measurements at scale S(L/16) were neither normal nor lognormally (natural log (ln)) distributed, although the latter. provided a somewhat better representation. Too few measurements were available to determine the probability distribution for scale S(L/4). The regularized semivariogram (range of 0.7 m) for scale S(L/16) was deconvoluted to provide estimates of the point semivariograms for both the actual and adjusted measurement scales, leading to spatial ranges of 0.21 and 0.30 m for actual and adjusted, respectively. With or without adjustment, dispersion variance analyses illustrated that the spatial structure estimate obtained from measurement scale S(L/16) was inconsistent with that obtained from measurement scale S(L/4). Thus, we conclude that the infiltrometer instrument fundamentally alters the infiltration process in such a way that measurements are only meaningful in a relative sense.

ID HYDRAULIC CONDUCTIVITY; SOIL; INFILTROMETER
AB The objective of this study was to investigate some field-oriented methods designed to characterize the flow rates of both the soil matrix and macropores near saturation. An apparent macropore conductivity was obtained by the difference between saturated and unsaturated hydraulic conductivities at - 0.6 kPa of soil water pressure. Saturated conductivities were measured in double-ring infiltrometers with tensiometers. Soil matrix conductivities were calculated from measurements of soil water pressures and drainage rate during redistribution and were also measured with a thin sand-cement crust. Another set of data for saturated and unsaturated conductivities was obtained from unconfined ponded measurements in 76.2-mm-diam. rings and a tension infiltrometer. Unsaturated conductivities and calculated apparent macropore conductivities from the crust and redistribution methods were comparable. Unsaturated conductivities and apparent macropore conductivities from the tension infiltrometer and unconfined ponded measurements were greater than those from the infiltration-redistribution method. We concluded that apparent macropore conductivity for the profile can be characterized by using ponded infiltration rates and matrix conductivities near saturation determined from redistribution data. This method accounts for the continuity of the macropore flow system in subsurface layers and involves a larger area for macropore infiltration measurement.

AB Assessing potential long-term forest productivity requires identification of the processes regulating chemical changes in forest soils. We resampled the litter layer and upper two mineral soil horizons, A and AB/BA, in two aggrading southern Appalachian watersheds 20 yr after an earlier sampling. Soils from a mixed-hardwood watershed exhibited a small but significant decrease in soil pH. Extractable base cation content declined substantially in both mineral horizons. For example, Ca2+ levels in the A horizon fell from 236 kg ha-1 in 1970 to 80 kg ha-1 in 1990. Proportionally, the decline was greatest for Me2+, which dropped from 111 to 20 kg ha-1. A white pine (Pinus strobus L.) plantation was planted in 1956, after clear-felling hardwoods and recutting sprouts for 15 yr. Soil pH and base cation concentrations declined in the A horizon from 1970 to 1990. Soil pH declined from 5.9 to 5.0 and Ca2+ levels from 534 to 288 kg ha-1. Cation content did not change significantly in the AB/BA soil horizon. Nutrient budgets were constructed using these soil and litter data plus existing data on weathering rates, forest productivity, and hydrologic fluxes and associated chemistry. Decreases in soil base cations and soil pH are attributed to leaching and to the sequestration of nutrients in biomass.

AB Understanding environmental and residue influences on decomposition and nutrient dynamics under diverse conditions is critical for efficient resource management. Our objective was to evaluate the influence of water on decomposition and N dynamics for surface and buried residues. Decomposition of alfalfa (Medicago sativa L.), grain sorghum (Sorghum bicolor [L.] Moench), and winter wheat (Triticum aestivum L. emend. Thell.) residues in fiberglass bags on the surface or buried at 120 mm in Pullman soil (fine, mixed, thermic Torrertic Paleustoll) at Bushland, TX, was measured from May 1990 to May 1991. A line-source sprinkler provided five water regimes (336, 287, 166, 60, and 5 mm) while precipitation provided 305 mm water. Decomposition coefficients (k) were greater for alfalfa than for wheat or grain sorghum and were greater for buried than for surface residues. Rate coefficients increased linearly with water applied. The increase was greater for alfalfa than for sorghum and wheat. Net N mineralization occurred from alfalfa residues throughout the study. Net N immobilization was longer than 1 yr for surface wheat and sorghum and about 0.33 yr for buried residues. Both N(max) (grams N immobilized per kilogram of original biomass) and N(eqv) (grams N immobilized per kilogram of biomass loss) were influenced by crop and placement but not water regime. The N(max) value was similar for surface wheat and sorghum residues but was 50% lower for buried wheat than for sorghum. The N(eqv) indicated the N requirement of microorganisms was less for buried than for surface residues. Water and residue quality interactions affecting decomposition and N dynamics should be considered in residue management strategies for soil protection and nutrient cycling.

AB The direct application of quantitative soil-landscape models for soil mapping has been limited by technological constraints. This study combines a statistically based soil-landscape model and geographic information system (GIS) technology to create soil drainage class maps. An existing soil-landscape model that predicts soil drainage class from parent material, terrain, and surface drainage feature proximity variables was used. A digital geographic database of parent material, terrain, and surface drainage feature proximity variables stored in a geographic information system were used as model inputs. Combinations of these landscape variables were defined by overlaying the digital maps and by applying the soil-landscape model to create predictive maps of soil drainage class probability and most-likely soil drainage class. The modeled soil drainage class map agreed with an Order II (1:20000 scale) soil survey for 67% of the study area. A majority of the disagreement was attributed to areas predicted as somewhat poorly to moderately well drained by the model and well drained by the soil survey. This technique consistently assigns soil drainage class based on landscape attributes, documents the data and decision criteria used for drainage class assignment, estimates the uncertainty associated with drainage class assignment, and generates a digital map for GIS applications.

AB Sustainable use of soil resources can be assessed from management-induced changes in soil properties from long-term experiments. Such data are scanty, especially with regard to changes in soil physical properties. Therefore, soil physical and chemical analyses were performed 28 yr after initiating a crop rotation-tillage experiment on a well-drained Wooster silt loam soil (fine-loamy, mixed, mesic Typic Fragiudalf) at Wooster, OH. All combinations of three rotations (continuous corn [CC; Zea mays L.]; corn and soybean [Glycine mar (L.) Merr.] in a 2-yr rotation [CS]; and corn, oat [Avena sativa L.], and meadow in a 3-yr rotation [COM]) and of three tillage treatments (no-tillage [NT]; chisel plow [CP]; and moldboard plow [MP]) were maintained on the same plots for the entire length of study. All crops were grown every year. Soil properties studied for the 0- to 15-cm layer were:  structural stability of aggregates, bulk density, total porosity, penetration resistance, organic C, pH, cation-exchange capacity (CEC), and exchangeable K, Ca and Mg. Mean bulk densities measured prior to tillage treatments and planting were 1.18, 1.24, and 1.28 Mg m-3 for CC, CS, and COM rotations, respectively. The lowest bulk density was observed for the CC-NT combination. Total aggregation in CS was 26.9% greater than CC and 111.2% greater than COM. With tillage treatments, aggregation was in the order of NT>CP>MP. Rotation treatments had no effect on aggregate size. In accord with bulk density, the relative magnitude of organic C content was 100, 85, and 63 for CC, CS, and COM rotations, respectively.

AB Soil organic matter (SOM) is valuable, because of both its beneficial effect on soil quality and crop productivity and its potential to sequester C. Long-term experiments provide an opportunity to identify crop management practices that enhance or degrade soil quality. This study was initiated in 1931 to determine residue management effects on crop yield and SOM (organic C and N) in a winter wheat (Triticum aestivum L.)-fallow system. The soil is a coarse-silty, mixed, mesic Typic Haploxeroll. Treatments include (units ha-1 crop-1) 22.4 Mg manure, 2.24 Mg pea vine residue, 0, 45, and 90 kg N with and without spring burning of straw, and 0 kg N with fall burning of straw. Yearly C and N inputs and removals have been determined since 1976, and calculated for prior periods. Soil C and N have been determined at almost-equal-to 11-yr intervals. Manure, which supplies 111 kg N ha-1 crop-1, has consistently produced the highest yield and maintained the highest soil C and N contents. Other treatments initially yielded from 80 to 90% of the manure treatment, but have progressively declined in direct relation to decreasing soil N content. Low-fertility treatments currently yield from 43 to 57% of the manure treatment. The change in soil C and N with time is nearly linear for all treatments, and highly correlated with residue input. Treatment effects on soil C and N have been confined to the top 30 cm of soil, but there has been a slow steady decline in C and N in the 30- to 60-cm zone that is not related to residue management.

AB There is increasing need to develop models to assess the long-term effects of management practices on soil and environmental quality, and to test these models across a wide range of environments. The CENTURY model was used to simulate long-term management practices for wheat (Triticum aestivum L.)-fallow agriculture. The objectives were to compare the accuracy of predicted vs. observed data and use the model to help interpret observed data and to determine the long-term impact of crop management on C and N stabilization in soil. The model simulated grain and straw yield and grain N uptake within +/-10% of the observed data, and 0- to 30-cm soil C and N within +/-5%. Improvement in performance requires addition of a dynamic plant growth submodel to represent the effect of soil N on C and N allocation to roots, straw, and grain. Soil C changes were a linear function of aboveground C inputs; an input of 200 g C m-2 yr-1 (4650 kg straw ha-1) was required to stabilize soil C at its present level. Estimates of soil C stabilization efficiency ranged from 12 to 27% and was highest for the high N fertilizer treatment. Soil N stabilization efficiency was higher for organic N additions (37-46%) than for inorganic additions (18-26%). Inorganic N treatments had similar N removal in grain, higher other nonidentifiable N losses, but lower N stabilization in soil than organic N treatments. Soil N data suggest that mineralization of N from the 30- to 60-cm layer needs to be considered in the N budget, as nearly 39 g m2 were mine between 1931 and 1986.

ID WATER STORAGE; STRAW-MULCH; NITROGEN; YIELD
AB Winter wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] are extensively grown in the southern Great Plains on dryland and with irrigation, but yields often are low on dryland and irrigation water is limited. Because both crops respond well to timely irrigation, they sometimes are grown with limited irrigation. Thus, it was hypothesized that using limited irrigation for these crops would produce sufficient residues to increase soil water storage if conservation tillage practices were used. This study on Pullman soil (fine, mixed, thermic Torrertic Paleustoll) at Bushland, TX, determined the effects of residue management on soil water storage and use, yields, and yield components for wheat and sorghum grown in rotation with limited irrigation. Treatments were no-tillage with standing (T1) or shredded (T2) residues, and no-tillage after wheat and tillage after sorghum (T3). Tillage did not affect water storage after wheat, but storage ranged from 68 mm with T3 to 101 mm with T1 after sorghum. Water use by wheat ranged from 93 mm with T3 to 131 mm with T1, but tillage did not affect water use by sorghum. Tillage did not affect wheat yields because differences in soil water storage and use were small and irrigations minimized the water content differences. Tillage did not affect sorghum yields because using no-tillage during fallow after wheat resulted in similar water storage in all cases. This study showed that practices that retain surface residues are effective for producing wheat and grain sorghum in rotation under limited-irrigation conditions in the southern Great Plains.

AB Field and laboratory research was conducted to measure changes in extractable anions following wildfire in sagebrush (Artemisia tridentata Nutt.)-grass communities. Two sites were studied along the eastern Sierra Nevada front in northeastern California on coarse-textured Haploxerolls and Haplargids formed from granitic parent materials. Soils were extracted with 0.15% KCl and analyzed with high-performance anion exchange chromatography. Compared with unburned soils, significant (P less-than-or-equal-to 0.05) decreases in NO3- and orthophosphate, and significant increases in SO42-, acetate, formate, oxalate, and glycolate occurred immediately after wildfire in the surface 5 cm of under-shrub soil. Concentrations of organic acids in burned undershrub soils increased significantly (P less-than-or-equal-to 0.05) in the weeks following a wildfire. In shrub interspaces, largely occupied by cheatgrass (Bromus tectorum L.), concentrations of anions were similar in unburned and post-wildfire soils. Laboratory heating of under-shrub soil indicated that maximum amounts of KCl-extractable organic anions are produced at temperatures between 150 and 350-degrees-C, and that the length of time (up to 30 min) the soil was exposed to a given temperature considerably affected these amounts. Elevated concentrations of organic acids may influence seed germination, plant establishment, and mineral nutrition.

AB The numbers of beneficial and pest insects were studied in 0.2-ha plots of Deltapine 50 (DP-50) and Stoneville 506 (ST-506), cultivars of upland cotton, Gossypium hirsutum L, irrigated weekly or biweekly at Maricopa, AZ. Plant water stress, as measured by leaf water potential, was 13% greater at 13 days than at 7 days in plants irrigated biweekly. Numbers of Lygus hesperus Knight were greater in DP-50 than in ST-506 and Nabis alternatus Parshley were greater in weekly- than biweekly-irrigated plots. Plants of DP-50 had 46% more pink bollworm, Pectinophora gossypiella (Saunders), larvae in bolls at the end of the season than did ST-506. Plants irrigated weekly had 32% more pink bollworm larvae than plants irrigated biweekly. Leaves of ST-506 averaged 35% more eggs of the sweetpotato whitefly, Bemisia tabaci (Gennadius), per gram of leaf tissue than leaves of DP-50. Leaves of plants irrigated-biweekly had 27% more eggs and 35% more nymphs per gram than plants irrigated weekly. Samples of lint from the two cultivars irrigated biweekly bad 46% more reducing sugar than lint from the cultivars irrigated weekly. Results indicate that numbers of immature sweetpotato whitefly on cotton plants can be reduced by 47% and similarly the percentage of sugar in the lint by selecting a less susceptible cultivar and reducing plant water stress.

AB Seven sampling experiments. involving the cotton aphid, Aphis gossypii Glover, were conducted during the 1990 through 1992 growing seasons. Results demonstrated that the highest portion of the population was found consistently in the lowest portion of the plant canopy regardless of aphid density. We suggest the following sampling scheme for determining numbers of cotton aphids during the cotton growing season: 1) first three weeks after planting (plant emergence to fourth true leaf) - use whole plant washes; 2) fourth through sixth week after planting (fourth leaf to pinhead square) - sample the fourth fully expanded leaf from the terminal; 3) seventh through ninth week after planting (pinhead square to first-bloom) - sample the first main stem green leaf about one-third the distance from the terminal; and 4) remainder of the season (first bloom to end of season) - sample the first main stem green leaf above the first basal fruiting branch.

AB The effects of aphid prey species on immature development and survival of Cycloneda ancoralis (Germar) were studied. Cycloneda ancoralis larvae fed Aphis gossypii Glover and Aphis helianthi (Monell) had longer developmental times than those fed Diuraphis noxia (Mordvilko) or Lypaphis erysimi (Kaltenbach). Development times did not differ significantly between sexes. Percent survival from egg hatch to adult eclosion did not differ significantly among larvae fed different aphids. The weight of newly eclosed adults differed significantly among C ancoralis fed different aphids and also differed between sexes; females weighed more than males. Individuals fed A. gossypii weighed least, while those fed L erysimi weighed most. The total number of aphids eaten by C ancoralis larvae differed significantly among individuals fed different aphid species. Larvae fed A. gossypii consumed more aphids than larvae fed other aphid species. Larvae fed D. noxia consumed the fewest aphids.

AB N-epsilon-lithocholyl lysine (NELL) is a component of tissue-bound lithocholic acid (TBL). The isolation of NELL from native protein sources was simulated by hydrolysis of lithocholyl-bovine serum alburmin (BSA) (synthesized by coupling lithocholyl-N-hydroxysuccinimide to fatty acid-free BSA) by digestion with a mixture of 6N HCl-propionic acid at 70 C for 3 h under partial vacuum. NELL was isolated on a reversed phase Sep-Pak C-18 column and converted to either a fluorophor with fluorescamine or to a chromophor with dimethylaminoazobenzene isothiocyanate for subsequent HPLC using appropriate fluorescence or UV/visible absorption detectors. The procedure described here is quantitative, highly sensitive, and not dependent upon the use of Clostridial choranoylamino acid hydrolase, the activity of which is sometimes blocked by steric hindrance on the substrate. Using this procedure we have demonstrated the presence of TBL in native histones.

AB Butanetetracarboxylic acid and citric acid are two multifunctional carboxylic acids that have potential for use in formaldehyde-free durable press finishing of fabrics. In this study these acids were investigated as cellulose crosslinking agents for modifying the wet performance of paper board The crosslink reaction involves the formation of two ester linkages per acid molecule to the hydroxyl-rich surface of cellulose to form a covalently linked structure that restricts the swelling action of water. All wet properties of ester crosslinked paperboard were significantly improved, as were dimensional stability and creep performance, two important dry properties-stretch and tensile energy absorption-were seriously decreased. For speciality products where water-soak properties of stiffness, dimensional stability, and reduced creep are important and dry toughness is not important, ester crosslinking may be a solution to material needs. Ester crosslinking eliminates the problems that are encountered with formalldehyde crosslinking. It also affords a pad-dry-cure process that is compatible with paper machine operation and yet has the advantage of a delayed cure option.

ID YARN
AB Fabrics constructed from unique staple-core (SC) and conventional intimate blend (IB) yarns were compared before and after durable press (DP) finishing. The SC and IB yarns were spun on the same spinning machine, with or without described modifications. The IB yarns were a homogeneous mix of cotton and polyester; the SC yarns consolidate the high tenacity polyester in the center of the yarn with cotton on the outside. The patented SC spinning method produced fabrics that look and feel like cotton and approach or exceed the properties of IB fabrics. The SC, IB and 100% cotton control fabrics were given DP treatments using dimethyloidihydroxyethyleneurea (DMDHEU) and butanetetracarboxylic acid (BTCA) methods. The superior or higher retention of properties in the DP-treated SC fabrics was attributed to the consolidation of the stronger, more extensible polyester in the core of their yarns. The successful commercialization of the technology could result in the use of SC fabrics for industrial or military applications where optimizing such properties as fabric strength, durability, comfort and appearance is required.

Metals can contribute to problems that occur in yarn manufacturing, fabric production, bleaching and dyeing processes. Disposal of both liquid and solid wastes containing certain metals must be carefully monitored and controlled. Cottons varying in growth area, variety and harvest season were analyzed for potassium, magnesium, calcium, sodium, iron, copper, manganese, zinc, lead and cadmium contents by atomic absorption spectroscopy. Metal contents varied significantly between years and between growth areas. Potassium was the dominant metal (2000-6500 ppm) followed by magnesium and calcium (400-1200 ppm), sodium (100-300 ppm), iron (20-90 ppm) and zinc, manganese and copper (1-10 ppm). Lead and cadmium were not detectable in any of the cottons at test sensitivity limits of about one ppm.

AB The first ''complete'' genetic linkage map of Sorghum section Sorghum is described, comprised of ten linkage groups putatively corresponding to the ten gametic chromosomes of S. bicolor and S. propinquum. The map includes 276 RFLP loci, predominately detected by PstI-digested S. bicolor genomic probes, segregating in 56 F-2 progeny of a cross between S. bicolor and S. propinquum. Although prior cytological evidence suggests that the genomes of these species are largely homosequential, a high level of molecular divergence is evidenced by the abundant RFLP and RAPD polymorphisms, the marked deviations from Mendelian segregation in many regions of the genome, and several species-specific DNA probes. The remarkable level of DNA polymorphism between these species will facilitate development of a high-density genetic map. Further, the high level of DNA polymorphism permitted mapping of multiple loci for 21 (8.2%) DNA probes. Linkage relationships among eight (38%) of these probes suggest ancestral duplication of three genomic regions. Mapping of 13 maize genomic clones in this cross was consistent with prior results. Mapping of heterologous cDNAs from rice and oat suggests that it may be feasible to extend comparative mapping to these distantly-related species, and to ultimately generate a detailed description of chromosome rearrangements among cultivated Gramineae. Limited investigation of a small;number of RFLPs showed several alleles common to S. bicolor and S. halepense (''johnson-grass''), but few alleles common to S. propinquum and S. halepense, raising questions about the origin of S. halepense.

AB Adoption of the high volume instrument (HVI) classification system for the official marketing criteria for cotton coupled with the separation of color and trash into different grade components requires that ginners and producers be knowledgeable of the impact of gin equipment on color and trash. Several studies indicated that gins can increase the perceived color grade of cotton by as much as two grades and that Spotted and Light-spotted cotton could be improved to Light-spotted or White color grades. Consideration of the effect of individual equipment in a cotton gin in three recent studies indicated that the seed cotton cleaners did little to improve color but did improve trash grade. Further analysis showed that lint cleaners improved the color of cotton. In these studies, Rd (grayness or reflectance) was increased by about 4.4 units whereas +b (yellowness) was increased only about 0.5 units. Much of the improvement in color was attributable to the removal of trash from the sample. Since lint cleaners remove substantial amounts of trash, they must continue to be used to improve the color of cotton.

DE ALTIMETER; AERIAL APPLICATION; RELEASE HEIGHT; RANGING SENSOR
AB A laser-based altimetry system was developed to measure the low above-ground-level (AGL) altitudes that agricultural aircraft typically encounter during aerial applications. The laser altimetry system was evaluated on-board an aircraft under various conditions. Distance* signals of a range-finder, determined based on the time of flight of laser pulses reflected by a target were corrected for varying pitch angle of the aircraft to indicate AGL altitudes dagger using an angle sensor.
   Effects of ground speed (193 to 241 km/h), AGL altitude (1.8 to 7.9 m), ground surface condition (hard surface, bare soil, cotton field, peanut field, wheat field), and other operating conditions (boom, hopper load) were investigated Ground surface condition was the only variable that significantly affected the difference between the true and laser-measured AGL altitudes. Percent errors of the measured AGL altitudes over hard surfaces ranged from -0.8 to 2.1% with standard deviations varying from 2.9 to 5.2%. The laser altimetry system sensed part of the crop canopy height, resulting in an offset of AGL altitude. The altimetry system provided repeatable measurements of AGL altitudes with consistent off sets over crop canopies.

AB The Erosion Productivity Impact Calculator (EPIC) model was applied to four fields established in ''tall'' fescue (Festuca arundinacea Schreb.) in northwestern Arkansas to predict runoff and transport of nitrogen, phosphorus, and sediment. Fertilizer form varied among the fields with two receiving inorganic fertilizer, one receiving poultry (Gallus gallus domesticus) litter, and one receiving poultry manure. Soil and grazing parameters also differed among fields. Runoff and nutrient/sediment transport observed over 20 months were compared to EPIC predictions generated without calibration. Significant correlation between event predictions and observations were found in half the cases. There was significant correlation between observed and predicted calendar year total transport for all outputs except nitrate-nitrogen. The findings indicate that EPIC can accurately reflect runoff quality trends when executed without calibration for pasture fields in northwestern Arkansas.

AB The Green-Ampt infiltration equation is used in many different hydrologic models. The effective hydraulic conductivity parameter (K(e)) within this equation is needed to obtain reliable estimates of infiltration and runoff. In this study, a method was developed for calibrating K(e) for the Green-Ampt equation as integrated with the WEPP continuous simulation model using a series of rainfall-runoff events on natural runoff plots. Optimum values of K(e) were obtained at seven locations, and the average Nash-Sutcliffe model efficiency for the Green-Ampt/WEPP predictions of runoff on an event basis was 0.46 using these K(e) values. Green-Ampt/WEPP tended to overpredict runoff on the small events and underpredict runoff on the larger events. This bias could not be corrected through calibration and indicates a structural flaw in the Green-Ampt equation, the WEPP model, or the available data. Other estimates of effective hydraulic conductivity were obtained from five different parameter estimation methods based on relationships involving common soil properties and were used in the Green-Ampt/WEPP model to predict runoff at each of the locations. None of these methods of estimating the effective hydraulic conductivity consistently outperformed the others for all the data sets. The average Nash-Sutcliffe model efficiency obtained using the best estimated parameters was -0.16, indicating that considerable improvement was obtained with calibration.

AB The load-flow relationship of salt in drainage water was studied using drainage water flow and salinity data from an irrigation district on the west side of the San Joaquin Valley of California. Flow and salinity data were collected from the main district drain, individual drainage sumps, and two field sites. Linear regression was used to describe the salt load-flow relationship at each drainage site. The slope of the regression line for the salt flow in the main drain was different compared to the subsurface drainage sites because of the inclusion of surface runoff from irrigation in the main drain. The EC in the water from the subsurface drains was not correlated with the flow rate. Cluster analysis of the load-flow relationships of 45 individual drainage sumps indicated that the load-flow relationship for flow from the district could be characterized by one of three relationships.

ID PROTECTION; SOIL
AB Maintaining standing vegetative soil cover is an important method of wind erosion control. However, an improved physical understanding of the mechanisms by which standing vegetation control wind erosion is needed so the erosion control level of vegetation not previously tested in a wind tunnel can be calculated. In this report, a theoretical approach that accounts for both the surface friction velocity reduction and the saltation interception by standing stalks is proposed. The predictive ability of the theory is then tested using two previously published data sets from wind tunnel studies in which soil loss was measured. The results show a high correlation between plant area index of stalks and soil protection. However, some initial tunnel experimental data on simulated plants with two movable leaves indicate that both plant area index and aerodynamic roughness may be needed to fully assess the erosion control level of canopies with leaves.

AB Total hydraulic resistance on an upland agricultural site nay be influenced by several factors including standing vegetation. In this laboratory study, Darcy-Weisbach roughness coefficients were measured for corn, cotton, sorghum, soybeans, sunflower, and wheat vegetation. Experimental variables used in this investigation in addition to crop type included plant population, row spacing, row orientation, and flow rate. For some of the experimental tests, a single row of vegetation was oriented within a flume parallel to the principal flow direction. For the remainder of the tests, rows of vegetation were placed perpendicular to the flow using row spacings and plant populations recommended by crop management specialists. Measurements of discharge rate and flow velocity were used to calculate roughness coefficients for Reynolds number values ranging from approximately 550 to 22,000. Regression equations which relate roughness coefficients to plant population, row spacing, and Reynolds number were developed from the laboratory data. With the exception of wheat placed perpendicular to flow, roughness coefficients produced by standing vegetation were negligible. On upland agricultural areas, total hydraulic roughness will be influenced primarily by frictional drag over the soil surface, and residue and ground cover.

DE TILLAGE; RESIDUE MANAGEMENT; WATER CONSERVATION
ID SOIL; RAINFALL
AB Dryland crops produce limited amounts of residue, thus the water conservation benefits of no-tillage (NT) may be reduced.  We compared infiltration, runoff, and water conservation effects of NT with stubblemulch (SM) tillage at Bushland, Texas, in the semiarid southern Great Plains. From 1981 to 1992, we cropped six field-sized (2 to 4 ha) graded-terraced watersheds in a dryland, three-year, winter wheat (Triticum aestivum L.)-sorghum [Sorghum bicolor (L.) Moench]-fallow (WSF) sequence. There were three pairs of watersheds in the sequence, each with NT and SM treatments maintained on the same watersheds each year. Runoff was measured with H-flumes from each watershed beginning in 1984. Infiltration differences were measured with a rainfall simulator in 1990 and 1991. We compared soil water storage during fallow to evaluate the water conservation effectiveness of tillage treatments. Terminal infiltration rates were similar for both tillage systems; however, infiltration rates declined much more rapidly with NT than with freshly tilled SM, primarily due to surface sealing even though residue coverage exceeded 50% on NT. Cumulative infiltration after 2 h of simulated rainfall was 90% greater on SM than on NT for tests conducted during fallow after sorghum, and 26% greater during fallow after wheat. Infiltration was greater on SM because tillage destroyed the consolidated surface crust, decreased bulk density, and increased surface roughness and depression storage capacity. The first artificial rainfall application compacted and smoothed the surface on the SM treatment; thus, infiltration during subsequent tests was similar for both tillage systems. Storm runoff measured with H-flumes averaged 25.5 and 40.1 mm/year for eight cycles of WSF for SM and NT treatments, respectively, with most runoff occurring during fallow periods. Despite greater surface runoff from the NT system than from the SM system, NT management resulted in improved water conservation due to reduced evaporation. Total plant available soil water storage during fallow after sorghum was 18% greater with the NT treatment and 10% greater during fallow after wheat than for soil water storage obtained with the SM treatment. More intensive cropping with less fallow appears possible on drylands by using NT management.

AB Measuring the amount of light transmitted through an apple has had limited success for detecting watercore in apples when the measurements were made soon after harvest. However, errors associated with this technique when applied to apples coming out of cold storage has yet to be determined Using a machine vision system to view the stem-end of the apple while illuminating the calyx, the intensity of light transmitted through individual apples was measured biweekly for 14 weeks in 1990. The mean gray-level of the pixels within a square window centered about the stem was representative of the intensity of the light transmitted through the fruit. The intensity of light transmitted through the fruit decreased with time for all classes of watercored fruit. Based upon the initial levels defined for each class, this decrease in light transmission resulted in misclassifying watercored fruit as watercore-free at the end of the time study. Of 72 fruit initially classified as severely watercored, 18% of the fruit were misclassified as watercore-free, because three apples still had evidence of watercore, while eight fruit exhibited internal browning, due to watercore.

AB Data from Griffin (1974) and that of Urquhart and Williams (1924) were used to evaluate available equilibrium moisture content models at normal temperature and at elevated temperatures (up to 90-degrees-C). Models evaluated included the Henderson and Perry (1976), a simple cubic polynomial, and the BET [Brunauer, Emmett, and Teller (1938) as modified by Dent (1977)]. All three models were evaluated for lint equilibrium moisture content at normal temperature. The BET model gave the best fit, but the simpler models gave satisfactory results for engineering calculations. Only the BET model gave adequate fit for variable temperature applications. Equilibrium moisture content is important in the processes involved in lint spinning. A reasonable amount of data is available on moisture absorption, but there is a lack of data on the desorption process. Since drying lint in seed cotton samples is a desorption process, a set of equations were devised to convert from one process to the other by a simple calculation.

The strength and stiffness of red maple glulam timber beams were predicted using ASTM D3737 procedures and then compared to data from 45 test beams, 15 each of 3 sizes. The results show that ASTM D3737 procedures conservatively predict the strength and satisfactorily predict the stiffness of red maple glulam timber beams and that red maple beams with flexural strength of 16.5 MPa (2400 psi) and stiffness (MOE) of 12.4 GPa (1.8 x 10(6) psi) are technically feasible. Also, the volume effect for the strength of the red maple glulam timber test beams was similar to the published volume effect for softwood glulam beams.

There was a strong positive correlation between flowering and seedling height; female flower production was stimulated by both a declining photoperiod during bud development and GA4/7 treatment; and there was an interaction between GA4/7 treatment and family, such that the difference in flowering intensity between a late-flowering and an early-flowering family was eliminated by GA4/7 treatment. The results suggest that the genetic control over the time of onset of flowering, and GA4/7-induction of flowering depend on a common mechanism.

DE AUTOCORRELATION; VOLUME EQUATIONS
AB Individual tree volume ratio models and associated taper functions are frequently used to estimate merchantable volume of trees to specific top diameters.  However, little consideration has been given to the correlation between successive observations that exists in these models.  An econometric procedure that corrects for this autocorrelation is presented.  The corrected model is, in theory, closer to the ''true'' model form and possesses confidence intervals that are more realistic than those given by uncorrected models.

AB Four recombinant vaccinia viruses expressing different portions of the dengue type I virus (DEN-I) genome (C-prM-E-NS1-NS2A-NS2B; prM-E; prM-E-NS1-NS2A-NS2B; or NS1-NS2A) were constructed in order to establish the most immunogenic configuration of DEN-1 proteins. Both recombinants producing prM and E in the absence of c induced the synthesis of extracellular forms of E in vitro. Mice inoculated with these two recombinants produced DEN-I neutralizing (NEUT) and haemagglutination inhibiting (HAI) antibodies. The other two recombinant vaccinia viruses, which did not induce the production of extracellular forms of E, did not induce E-specific immune responses. These results support our previous studies on the design of flavivirus-vaccinia vaccine candidates by showing the importance of co-expressing prM and E in order to induce the synthesis of extracellular E and to elicit NEUT and HAI antibodies.

AB A panel of monoclonal antibodies to bovine leukocyte differentiation molecules was used to evaluate peripheral blood and splenic lymphocytes from cattle of various ages. The major population of peripheral blood lymphocytes from neonatal calves was gamma delta T-cell receptor (TCR1) positive, as determined by TCR1-N12 expression. TCR1-N12(+) lymphocytes were decreased in number in older calves, and were lowest in adult cattle. The major subpopulation of TCR1-N12(+) cells from peripheral blood coexpressed WC1, but not BoCD2. A small subpopulation of peripheral blood TCR1-N 12(+) cells from cattle of all ages coexpressed BoCD2, but not WC1. The TCR1-N12(+)BoCD2(+) lymphocytes made up the largest TCR1-N12(+) lymphocyte subpopulation in spleens of both calves and adults. The TCR1-N12(+)WC1(+) + splenic lymphocytes were present as a small population. The data indicate that two subpopulations of TCR1(+) lymphocytes are present in cattle of all ages. These two subpopulations are differentially distributed between blood and spleen, with TCR1-N12(+)WC1(+) lymphocytes predominating in blood, and TCR1-N12(+)BoCD2(+) cells predominating in spleen.

AB Gamma interferon produced by porcine lymphocytes (nPoIFN gamma) in response to stimulation with phorbol-myristate-acetate (PMA) and phytohemagglutinin (PHA) was monitored by a radioimmunoassay (RIA). The RIA was developed with antibodies raised in rabbits against recombinant porcine IFN gamma (rPoIFN gamma) and made monospecific on a rPoIFN gamma/Sepharose matrix. This anti-PoIFN gamma antibody was shown to bind and neutralize rPoIFN gamma specifically and to cross-react with bovine IFN gamma but not with murine IFN gamma, or porcine IFN alpha. The nPoIFN gamma levels produced by lymphocytes in response to PMA and PHA were at least two-fold higher than control lymphocytes as measured by the RIA in culture fluids. These culture fluids were fractionated on Concanavalin A Sepharose (Con A/Seph) and anti-rPoIFN gamma/Seph in attempts to evaluate the induced nPoIFN gamma further. The separation was monitored by RIA and showed that nPoIFN gamma was retained on Con A/Seph suggesting the presence of sugar residues on the molecules. Pools of Con A/Seph fractions, positive in RIA, were separated further on the anti-rPoIFN gamma/Seph matrix where a total adsorption of nPoIFN gamma occurred. On a weight basis, the eluates from the anti-rPoIFN gamma/Seph had a reactivity in RIA at least four times higher than the fractions derived from Con A/Seph. This indicated that the nPoIFN gamma remained immunochemically reactive after being eluted from Con A/Seph and that the separation on anti-rPoIFN gamma/Seph chromatography was specific. Purified nPoIFN gamma exhibited a major band with the same migration characteristics of rPoIFN gamma in PAGE-SDS electrophoresis and several minor bands when reacted with I-125 anti-rPoIFN gamma antibody in Western blots. A total loss of reactivity to antibody after radioiodination of nPoIFN gamma, however, prevented the confirmation of these results by immunoprecipitation. A direct, rapid and sensitive immunoassay for measurement of the relative levels of nPoIFN gamma present in biological fluids is presented and this method could be a useful complement to bioassays for IFN gamma.

AB Five Holstein heifers (approximately 8 months of age and weighing 225-275 kg) were inoculated subcutaneously with 1,000 TCID50 of rinderpest virus, virulent Kabete O strain. They become clinically ill 2 to 5 days post-inoculation, with fever (40 C to 41.5 C), conjunctivitis, and diarrhea. All were euthanatized when moribund at 6 days postinoculation. The following tissues were collected in formalin, embedded in paraffin, and subsequently subjected to histopathologic and immunohistochemical examination: tongue, buccal mucosa, soft palate, esophagus, rumen, abomasum, duodenum, jejunum with and without Peyer's patch, ileum, cecum, proximal colonic lymphoid patch, spiral colon, eyelid, gall bladder, spleen, tonsil, trachea, lungs, and numerous lymph nodes. Immunohistochemical examination was accomplished using a primary rabbit anti-rinderpest antibody, and either a peroxidase-diaminobenzidine or alkaline phosphatase-Vector Red detection substrate system. In the lymph nodes, spleen, and tonsil, depletion of lymphocytes from all areas was extensive, with antigen most prominent in persisting reticular cells throughout the tissues. In the intestine, necrotizing and ulcerative changes in the mucosa were extensive and widespread. Damage was most severe in areas overlying lymphoid patches. In both small and large intestine, antigen was distributed predominantly in epithelial cells, histiocytic cells in the lamina propria, and in remaining reticular cells of lymphoid patches. In oral mucosa, there were multiple ulcerations and numerous multinucleate syncytial cells, both containing and without antigen. Lungs and trachea had subtle yet consistent necrosis of epithelial cells, with antigen often distributed in a circumferential manner in epithelium of bronchioles.

AB Sixteen adult sheep (ten females, six males obtained from a dosed flock at National Animal Disease Center, Ames, IA) were experimentally infected with bovine respiratory syncytial virus strain 375 (BRSV), and lung tissues were stained for viral antigen. Two infected sheep were euthanatized at each of the following post-inoculation times: 12, 24, 36, 48, 72, 96, 144, and 192 hours. Lung, nasal turbinates, trachea, right cranial bronchial and mediastinal lymph nodes, liver, and spleen were collected for histologic evaluation. An indirect immunoperoxidase technique was performed on routine paraffin-embedded sections of lung tissue, trachea, turbinates, and bronchial and mediastinal lymph nodes to determine the location of the BRSV antigen. For lung tissue from each sheep 400 light microscopic fields at 160x magnification were examined for staining for BRSV antigen. Lung tissue was also collected for virus and bacterial isolation. Daily serum samples were taken for determination of anti-BRSV titers. Severe respiratory disease was not produced in any sheep. Bovine respiratory syncytial virus was isolated from lung tissue collected from all sheep up through 144 hours postinoculation At 12 hours post-inoculation (case No. 2) respiratory syncytial virus antigen was detected in bronchiolar epithelium and a mononuclear cell within an alveolar space. Lung tissue from the sheep necropsied between 24 and 144 hours post-inoculation (case Nos. 3-14) contained BRSV antigen in bronchiolar epithelium, type I pneumocytes, type II pneumocytes, alveolar macrophages, and mononuclear cells within alveolar spaces. Macrophages staining for viral antigen were rare. Bronchiolar and type I epithelial cells comprised the majority of infected cells. In a separate experiment, lung slices inoculated in vitro with either BRSV or ovine adenovirus did not stain for the respective antigens. Slices inoculated with parainfluenzavirus-3 did stain for that viral antigen.

AB In equimolar mixtures of L- and DL-proline, the vibrational spectra of the LDLL-mixture is not an average between that of the L- and the DL-isomers. Instead the DL-mixture is clearly intermediate between the L- and the LDLL-spectra. Adding L-isomer to the DL-isomer, the solid state spectra becomes less similar to that of the L-isomer. Replacing respectively the LL-half and the DL-half with a second amino acid, each set can significantly alter the conformation of proline and/or the second amino acid, even though both SetS (LDLL- and LLDL-mixtures) have identical structural composition. Large changes in spectral properties between LDLL- and LLDL-amino acids are consistent with diastereoismeric interactions between isomers. Infrared frequencies for chiral structures in an achiral localized environment are not predictive of the frequencies for the same chemical structures in a chiral environment.

AB An open reading frame, LMW8-DR, in the African swine fever virus (ASFV) genome possesses striking similarity to the lymphocyte membrane antigen CD2. All characterized CD2 domains, including the amino-terminal signal sequence, IgV, hinge, IgC2, stalk, transmembrane, and proline-rich carboxy cytoplasmic domains, are highly conserved in the ASFV gene. Critical residues for the binding of the lymphocyte function-associated antigen (LFA-3) and CD59 and for T-cell activation are also partially conserved. LMW8-DR is actively transcribed in ASFV-infected swine macrophages and Vero cells at late times in the infection cycle and Vero and COS cells transiently expressing the LMW8-DR open reading frame hemadsorbed swine red blood cells. The structural and functional similarities of LMW8-DR to CD2, a protein that is involved in cell-cell adhesion and immune response modulation, suggest a possible role in the pathogenesis of ASFV infection.

AB The foot-and-mouth disease virus (FMDV) genome contains a 5' untranslated region (S fragment) capable of forming a stem-loop structure of over 350 bases, which is separated from the remainder of the genome by a homopolymeric cytidylic acid tract (poly(C)) of variable length. The sequence of the S fragment of serotype Al? appears more similar to those of type O-1 or type C-3 than to subtype A(10). The relatively large difference between the S fragment sequences of two type A viruses suggests that the sequences per se of this region of the genome are not critical for the maintenance of function, and suggests the possibility of a relatively recent recombination event within the poly(C) region of the A(12) genome.

AB Two orbiviruses, epizootic hemorrhagic disease (EHD) and bluetongue (BTV) viruses, cause disease in domestic and wild ruminant species. The gene that encodes non-structural protein 1 (NS1) of EHD virus, serotype 1, was sequenced and compared to EHD and BTV NS1 sequences. The NS1 gene was found to be more conserved than the VP3 gene, and was selected as a target for polymerase chain reaction (PCR) amplification. The NS1 genes of several BTV viruses and another orbivirus, African horse sickness (AHS), were compared to the EHD NS1 genes. This information was used to develop a capture nested-PCR for detection and differentiation of EHD from BTV viral RNA.

AB Grape samples from nine progeny populations totaling 580 individual seedlings were evaluated organoleptically for the stenospermic character by four independent judges. These subjective evaluations were correlated to a standard objective procedure for evaluating stenospermy, as well as other variables associated with the sinker content of each sample. Correlations were diverse between organoleptic evaluations and calculated variables. Organoleptic evaluations more closely agreed with the objective stenospermic evaluation for seeded grapes. Highest correlations were realized between organoleptic evaluation and relative seed mass. These results indicate that organoleptic evaluations should not be used in genetic studies to discern between seeded and stenospermic accessions.

TI VISUALIZATION OF TRENDS AND FLUCTUATIONS IN CLIMATIC RECORDS
SO WATER RESOURCES BULLETIN
LA English
DT Article
DE ANNUAL PRECIPITATION; RESCALED ADJUSTED PARTIAL SUMS
ID SHIFT; LOCATION
AB Small systematic changes in climatic records am often poorly visualized by standard time series plots because they are usually hidden by the magnitude and variability of the data values themselves. A visualization approach based on the rescaled adjusted partial sums (RAPS) which overcomes the above-stated short-comings is presented. This visualization highlights trends, shifts, data clustering, irregular fluctuations, and periodicities in the record. Additional information on the number, magnitude, shape, frequency, and timing of fluctuations and trends can also be inferred. The visualization approach can be used for preliminary visual inspection of a time series, to gain a feel for the data, and/or to guide and focus subsequent statistical tests and analyses. It is not intended as a substitute for standard statistical analysis. Alternatively, the visualization approach can be used to display findings of a time series analysis. The capabilities and limitations of the approach are discussed and illustrated for two time series of annual rainfall values.

AB This glossary provides standard definitions for many of the terms used in avian conservation biology. We compiled these definitions to assist communication among researchers, managers, and others involved in the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight. We used existing glossaries and recent literature to prepare this glossary. The cited sources were not necessarily the first ones to use the terms. Many definitions were taken verbatim from the cited source material. Others were modified slightly to clarify the meaning. Definitions that were modified to a greater extent are indicated as being adapted from the originals. Terms that have been used in more than one way by different authors are listed with numbered alternative definitions if the definitions differ substantially.

AB The toxin-encoding linear plasmid systems found in Pichia acaciae and Kluyveromyces lactis yeasts appear to be quite similar, both in function and structural organization. By Southern hybridization, a linear plasmid of P. acaciae, pPacl-2, was found to hybridize to the second open reading frame (ORF2) of K. lactis plasmid pGKL1, known to encode the alpha and beta subunits of the K. lactis toxin. A 1.7 kbp segment of pPacl-2 DNA was cloned, sequenced and shown to contain four regions of strong homology to four similarly oriented regions of K. lactis ORF2. This 1.7 kbp fragment also contained an ORF of 1473 bp that could encode a protein of similar to 55.8 kDa. Like the a subunit gene of K. lactis ORF2, a very hydrophobic region occurs at the N-terminus, perhaps representing a signal sequence for transport out of the cell. Unlike K. lactis ORF2, however, the encoded polypeptide is much smaller and lacks a recognizable domain common to chitinases. The structure of a toxin that includes the translation product of this P. acaciae ORF would likely be quite different from that of the K. lactis toxin. Analysis of the upstream region of the P. acaciae ORF revealed an upstream conserved sequence identical to that found before ORFs 8 and 9 of pGKL2. A possible hairpin loop structure, as has been described for each of the four K. lactis pGKL1 ORFs, was found just upstream of the presumed start codon. The similarity of the promoter-like elements found in the linear plasmid genes of these diverse yeasts reinforces the idea of the existence of a unique, but highly conserved, expression system for these novel plasmids. The sequence has been deposited in the GenBank data library under Accession Number U02596.
