Commercially available polyethylene glycol capillary columns were compatible with injections of highly acidic aqueous solutions which were required for this relatively strong acid. Using monochloroacetic acid as an internal standard, a coefficient of variation of less than 2% was routinely obtained from replicate injections of a 100 mug/ml solution of sodium monofluoroacetate in 1 M HCl. The monofluoroacetic acid/monochloroacetic acid detector response ratio was a linear function of sodium monofluoroacetate concentration from 5 to 200 mug/ml. Since derivatization is not required and mass spectrometric identification of monofluoroacetic acid is obtained, the method offers advantages over previously described chromatographic methods for the determination of sodium monofluoroacetate. The average analyte recovery from 30 to 40 g biological samples fortified with between 2.5 and 100 mg of sodium monofluoroacetate was 81% with relative standard deviation typically less than 7%. The instrument limit of detection was 200 pg sodium monofluoroacetate when the detector was operated in the selected ion monitoring mode.

The 4-trans-8-cis(iso-MEL) and the 4-cis-8-trans(epi-MEL) isomers, and a fourth related compound, featuring a 3-fused 5-membered ring skeleton were additionally formed. All four compounds were fully characterized by use of 1D and 2D NMR techniques. Examination of the long-range coupled proton network by delayed COSY experiments allowed determination of the relative configuration of these 4,8-diaryl-3,7-dioxabicyclo[3.3.0]octan-2-one structures. The pathways followed by these long-range proton couplings and implications of the long-range and vicinal couplings with respect to favoured conformations are discussed.

These genes span 3.1 and 2.8 kilobases (kb), respectively. Apolipoprotein C-III gene is interrupted by three intervening sequences of 613, 135 and 1699 bp, respectively. The open reading frame encodes a protein of 99 amino acids which is 87% similar to the human. The cynomolgus mature protein is 79 residues long. Thr-74 is also present what might allow the formation of O-glycosidic linkage observed in the human protein. Apolipoprotein A-IV gene consist of two intervening sequences of 352 and 774 bp, respectively. The open reading frame encodes a protein of 429 amino acids which is 87% similar to the human. The cynomolgus mature protein is 409 residues long, 33 amino acids longer than the human, due to an insertion of 33 residues in its COOH-terminal region. This insertion is mainly composed of glutamine and glutamic acid, which confers cynomolgus apolipoprotein a higher hydrophilicity. C1 UNIV LOWELL,DEPT CLIN SCI,LOWELL,MA 01854.

The gene spans 1.4 kilobases (kb). The complete nucleic acid sequence of the apolipoprotein A-II gene has been determined, establishing that the gene is interrupted by three intervening sequences of 170, 273 and 394 bp, respectively. The open reading frame encodes a protein of 100 amino acids, and shows 94% sequence similarity with its human equivalent. Both apolipoproteins have identical signal peptide. A noticeable feature is the substitution of mature human Cys-6 for Ser. This change explains the existence of cynomolgus apolipoprotein A-II as a monomer and may have important consequences in the kinetics of this apolipoprotein.

The procedure indicates if domination with respect to an importance order (ordinal ranking) of the attributes can be easily detected if one assumes an additive value function. The concept of importance order (or partial information) domination has been developed in the literature but has been ignored in most multi-attribute applications. We show how closed form solutions of the linear programs needed to determine strong dominance are derived and present a graphical display of the results in the context of an example. The procedure outlined is practical to use and the results are easy to interpret. An example illustrates how one might apply the method to decision making in farm management with respect to water quality issues. C1 UNIV ARIZONA,DEPT SYST & IND ENGN,TUCSON,AZ 85721.

The influence of zinc on fusarin C synthesis and lipid composition was dependent on the initial glucose concentration. In cultures supplied with 30 g/l glucose, zinc inhibited fusarin C and lipid synthesis by diverting common substrates to ethanol synthesis. Zinc-supplemented cultures with 90 g/l glucose had ample carbon substrate to produce both ethanol and fusarin C. More total lipid with a higher unsaturated fatty acid content (more oleic acid and less stearic acid) was found in F. moniliforme biomass produced in zinc-deficient media.

Four soil pretreatment procedures were compared: (1) air-dried, capillary wetted (AD-CW), (2) air-dried, tension wetted (AD-TW), (3) air-dried, slaked (AD-SL), and (4) field-moist, capillary wetted (FM-CW). Air-drying soils resulted in a greater quantity of aggregates in the coarser fractions ( > 250 mum), as compared to field-moist soils, with a consequent reduction in the finer fractions ( < 250 mum). Differences between methods of wetting air-dried soils were more pronounced for the clayey soils where both AD-CW and AD-SL resulted in a greater proportion (22-24%) of the soil mass in the finer fractions ( <250 mum), as compared with AD-TW (4.5%). The FM-CW procedure had the lowest coefficients of variation (2-8%) for repeated measurements. The AD-CW and FM-CW procedures were also used to compare the effects of cropping systems [conventional tillage (CT) (soybean/fallow), CT (sorghum/fallow), and no-tillage (NT) (sorghum/clover)], erosion classes (slight, moderate, and severe) and irrigation (drip-irrigated or nonirrigated) on water-stable aggregates ( > 250 mum). In general, water-stable aggregates increased with decreasing intensity of cultivation, increasing severity of erosion and irrigation. Air-drying soils resulted in less differences in water-stable aggregates between treatments, but provided more detailed information on the interactive effects of cropping system and irrigation as compared with the field-moist condition. Similar differences were observed in aggregate disruption rates that were calculated from the aggregates recovered after wet-sieving for intervals of 1-32 min. Although water-stable aggregates were lower by FM-CW, this procedure showed greater separation of treatment means (e.g. erosion classes) than the AD-CW procedure. We also compared single versus multiple-sieve techniques for describing the effects of pretreatment conditions on aggregate distributions. For the clayey Pacolet soil, a fine fractionation into eleven aggregate size classes revealed the greatest differences (P< 0.05) between the FM-CW and AD-CW procedures, while a coarse fractionation into macro- ( > 250 mum) and micro- ( < 250 mum) aggregates showed no differences. However, for the sandy Hiwassee soil differences in aggregate distributions between the FM-CW and AD-CW procedures were found at most levels of fractionation, but were not detected by comparing the calculated mean weighted diameters. In general, our findings emphasize the value of comparing soil specific responses to different pretreatment conditions, particularly those that compare the distributions of aggregates among size classes, as a means for describing environmental influences on soil structure.

This paper describes, utilizing data from Minirhizotron (MR) and miniature color video camera recordings, wheat (Triticum aestivum L.) and peanut (Arachis hypogae L.) seasonal rooting habits. Data for multiple and linear regression analysis were acquired by making root count (C(a), counts cm-2 MR) and root length (L(a), cm root cm-2 MR) measurements on the surface of MR during the plant growing season. Roots on the surface of MR were recorded on video cassettes, displayed on a video screen, and traced on cellulose acetate each sampling date. Root dynamics were determined by comparing successive tracings. Wheat root length density (L(v), cm root cm-3 soil) and root dry weight (W(v), g root cm-3 soil) were determined from soil cores. A correlation coefficient of 0.88 for a multiple regression expression describing C(a) as a function of cultivar, sampling date, and soil depth was obtained. Linear regression for C(a) as function of L(v), W(v), or L(a) were highly significant, and correlation coefficients with C(a) were 0.72, 0.69, and 0.82, respectively.

The role of the near-surface air temperature was to stabilize the otherwise noisy radiosonde profiles. The computational procedure was developed from standard Monin-Obukhov flux-profile relationships for the atmospheric surface layer. The measurements were made in the context of the International Alpine Experiment ALPEX at the Rietholzbach catchment in a region of complex rugged terrain of the Swiss Fore-Alps. The positive correlation (r = 0.7) between the profile derived values of H and those obtained at a central station of the catchment, supports the existence of a surface layer even above this very rough terrain. The values of latent heat flux (evaporation) obtained from these H values by means of the energy budget agreed well (r = 0.94) with lysimeter measurements at the central station.

Microclimatic information on this forest landscape is needed for both research and resources management purposes. In this paper, seasonal summaries and diurnal changes in air temperature and moisture, soil temperature and moisture, short-wave radiation, and wind velocity are quantified for recent clearcut (10-15 years old), edge, and adjacent interior old-growth Douglas-fir forest environments in southern Washington state, USA, over two growing seasons. Influences of local weather condition and edge orientation (relationship of edge to the azimuth) are also assessed. Over the growing season, daily averages of air and soil temperatures, wind velocity, and short-wave radiation are consistently lower, and soil and air moisture are higher, inside the forest than in the clearcut or at the edge. Daily differences (i.e. maximums minus minimums) of all variables are consistently lower in the forest, The microclimates at the edge and the clearcut show a variable relationship with regard to averages and differences. Between the edge and the forest, greater differences occur under clear sky conditions for air temperature, but under partial cloudy conditions for relative humidity and soil temperature. Edge orientation is critical in assessing solar radiation, soil moisture, and relative humidity. The highest variability in microclimate exists at the edge, rather than in either clearcut or interior forest, primarily because of the influences related to edge orientation. The supposition that edge microclimates are intermediate between clearcut and interior forest is consistently true only for wind velocity and solar radiation, not for temperature and moisture.

The colonization of this grass by the fungus follows the natural sequence of fescue seed germination, seedling and tiller growth. Infected grasses are natural and extensive, therefore tall fescue should be considered a symbiotic plant. The nature of this relationship at the population level is more appropriately described as an obligately biotrophic conjunctive mutualism. The use of this terminology at the population level describes the overall ecological effect; however, allowances must be made for infected tall fescue genotypes within the population that may not show any positive adaptive strategies. Genotypes of this later category may be categorized, possibly only transiently, as obligately neutral symbiotic. Infected genotypes of the earlier category offer adaptations to environmental stresses and may be exploited for these characteristics. Evidence from research is reviewed to indicate that selected genotypes within the population of tall fescue are more tolerant of environmental abiotic stresses than uninfected grasses. Infected tall fescue seed require more moisture to germinate than uninfected seed. Endophyte-infected seedlings require more nutrients than uninfected seedlings. Although infected tall fescue contains less soluble nitrogen which would encourage more predation, strains resulting from the stresses of insect herbivory are prevented because of an accumulation of an insect deterrent, toxins and their synergists. At the morphological level infected grasses show tolerance to water stress by early shedding of older leaves and rolling of younger leaves. Tolerance to water stress is further evidenced by low stomatal conductances and by development of an enhanced osmoregulatory system that produces increased cellular turgor pressure. One genotype of tall fescue contains polyols, some of which are absent in the uninfected clone. Infected tall fescue also shows increased efficiency to low soil nitrogen, possibly due to an increased level of glutamine synthetase which would enhance its competitive ability under low soil nitrogen. There is no endophyte effect of consequence on photosynthesis and associated processes in several genotypes of infected grasses.

However, tall fescue breeding programs have been affected greatly. The basic methods for genetically manipulating the grass have remained static. Tall fescue is an obligate out-crossing species, and most improvements are, therefore, captured in the form of an improved population developed through some form of mass or recurrent selection. What has changed is the breeder's ability to recognize genetic differences in the grass because of the confounding effect of A. coenophialum on plant phenotype. It is, therefore, critical that breeders recognize A. coenophialum status in their plants prior to selection. The other major change in tall fescue breeding since the discovery of the A. coenophialum/grass interaction is a tremendous increase in breeding activity.

Hyperthermia, vasoconstriction and perhaps increased activity of hepatic mixed-function oxidases are important effects. Perhaps secondarily intake is reduced by the above mechanisms and possibly by unpalatability factors. The decreased milk yield is considered a function of decreased intake and suppressed prolactin secretion. Evidence is discussed that corpora lutea in cattle are morphologically altered and consequently may not support a pregnancy. The effect of endophyte presence upon the outcome of pregnancy in the mare is considered a function of an alteration in placental function as a result of vasoconstriction.

We hypothesized that a crop grown in rotation might deplete soil water more than the same crop grown under monoculture because some negative factor associated with monoculture was alleviated. Water use efficiency (WUE) might also be improved by rotation. The objective of our study was to determine whether altered water uptake or altered WUE was associated with the yield increase observed when corn (Zea mays L.) and soybean [Glycine mar (L.) Merr.] are rotated. A long-term corn-soybean rotation experiment was,monitored in 1987 and 1988 to determine seasonal soil water status to 1.50m. Corn and soybean sequences monitored were: monoculture, first-year crop following 5 yrs of the other crop, second-year crop following 5 yrs of the other crop, and an annual alteration of the two crops. Compared with monoculture, yield was increased up to 30% when corn followed soybean and up to 11% when soybean followed corn. Average soil water depletion during the season by first-year corn was 16 mm greater than by continuous corn. The WUE in corn was related to cropping sequence at a moderate level of significance (p = 0.14). Seasonal soil water depletion by soybean was not changed by cropping sequence but overall WUE by first-year soybean was higher than by continuous soybean (p = 0.05). When there was a period with only sparse rainfall in 1988, corn had a greater water depletion than soybean and also a deeper zone of depletion. Both crops exhibited a greater water depletion when rotated. Frequent rainfall in 1987 sufficient to wet the soil below 0.30 m obliterated patterns of depleted soil water. Increased water use observed in first-year corn and increased WUE observed in first-year soybean (compared to monoculture) in both years suggest that rotation allows these crops to increase root surface or root activity and hence to improve grain yield.

This study assessed whether seed-row configuration and N fertilizer placement could alter growth and yield of barley (Hordeum vulgare L.) in the subarctic. Row spacing and N placement treatments established at Fairbanks, AK, during 1987 through 1989 consisted of equidistant-row planting (0.18-m equidistant seed rows) with N banded between alternate rows or broadcast and incorporated, and skip-row planting (skipping every third row of equidistant rows) with N banded between the two closely spaced rows or broadcast and incorporated. Plant characteristics evaluated included tiller and head density, straw and grain yield, N uptake, leaf area, and root length density. Soil core samples were extracted to approximately 1 m in the mid-interrow position near anthesis to determine root length density by the line intersect method. Tiller density was the primary yield component differing among treatments. Equidistant-row barley had more tillers which resulted in a higher head density, 40% higher leaf area, and higher grain and straw yields than skip-row barley. Rooting in the top 0.1 m or soil was more proliferous where N fertilizer was banded rather than broadcast, but total N uptake was not different among treatments. This study indicated that growth and yield of barley in the subarctic were favored by equidistant-row planting with either banded or broadcast N applications.

The objective of this study was to determine the response of osmotic potential, leaf proline concentration, and cell wall elasticity to water deficit for the C4 (warm-season) grasses 'Nebraska 54' indiangrass [Sorghastrum nutans (L.) Nash], 'Pathfinder' switchgrass (Panicum virgatum L.), and 'Pawnee' big bluestem (Andropogon gerardii Vitman), and the C, (cool-season) grasses, 'Ioreed' reed canarygrass (Phalaris arundinacea L.), and 'Lincoln' smooth bromegrass (Bromus inermis Leyss.). Other measurements included leaf water potential, soil water content, and osmotic adjustment. A field study at Mead, NE, and a complementary greenhouse study at the University of Nebraska, Lincoln, found osmotic adjustment occurred in response to water deficit for all species, and was greater for C4 than for C3 grasses. Despite less osmotic adjustment, C3 grasses had more elastic cell walls (low modulus of cell wall elasticity), which maintained turgor despite loss of water. Leaf proline concentration averaged 20 times greater in stressed compared to well-watered plants grown in the greenhouse. Proline accumulation in greenhouse-grown plants was much larger than observed under field conditions. The physiological role of proline accumulation was uncertain because even dramatic increases in leaf proline concentration were insufficient to influence osmotic potential.

Differences in response to P availability among six cultivars of white clover (Trifolium repens L.) were investigated in a series of pot experiments using a sand-alumina culture technique and two low P soils, an acid Hapludult with 2.6 mg Bray-P kg-1 and a calcareous Calciaquoll with 6.9 mg NaHCO3-extractable P kg-1. Plants were grown in the greenhouse or growth chamber for up to 63 d in solution [P] of 0 to 82 muM. Plant characteristics measured included dry mass and P concentration of shoots, coarse roots, and fine roots; P distribution within the plant; and root traits of total length, root hair length and number per unit root surface area, and root tip number. There were significant differences in shoot dry mass and P accumulation response curves among cultivars; cultivar rankings were consistent in sand-alumina and in soils, but differed from other reports in the literature. We found significant cultivar-by-solution [ P] interactions when only low vs. high P availabilities were compared, but not when response curves were generated and compared. Differences in herbage yield and P accumulation were associated with larger root systems, but there was no evidence of greater efficiency of P uptake or utilization in these cultivars.

However, leaching of fertilizer nitrate may accelerate the leaching of bases from the crop rooting zone, leading to an acidification of the topsoil and a reduction in crop yields. Our ojective was to investigate the influence of urea and legume green manure sources of N on crop yields, leaching of cations, and the fertility of the plow layer of a clayey Oxisol (Typic Acrudox) of the central Amazon basin. We established a split-plot field experiment near Manaus, Brazil where main plots received 2 levels of lime (0 and 4 Mt/ha CaCO3) and sub-plots were cropped with (i) a legume green manure (Canavalia ensiformes L. or Mucuna aterrima L.) followed by maize (Zea mays L.); (ii) maize receiving 300 kg ha-1 of urea-N, or (iii) left bare-fallow with an application of 300 kg ha-1 of urea-N. Plots were periodically sampled to 1.2 m during three cropping seasons. The field site received 4265 mm of rain during the experiment (16 mo). Legume crops accumulated between 142 and 280 kg ha-1 of N. The distribution of NO3 in the soil profile changed in a pattern consistent with leaching. All treatments lost Ca and Mg from the plow layer during the experimental period. Losses were greatest (500-1000 kg ha-1 for Ca and 50 kg ha-1 for Mg) in plots treated with urea and lime. Leaching of bases and the generation of acidity decreased base saturation in the plow layer of all treatments, but was minimized in plots receiving legume green manure N, perhaps because less inorganic N was applied and/or the legume crops recycled leached bases. Unlimed plots receiving urea, had the highest increase in acidity in the 0 to 30-cm layer and a corresponding 44% reduction in grain yield between the first and third maize crops.

LEAF-AREA AND DRY MASS SIMULATION SO AGRONOMY JOURNAL LA English DT Article ID SORGHUM AB Parameterization is a technique used by modelers to approximate the response of a physical system using an empirical function. This technique has the advantages that it reduces the complexity of models and often simplifies their input requirements, making the models more easily usable for operational purposes. In this study, a relatively simple model of leaf area and dry mass growth for the gramineous crops was developed to demonstrate the use of parameterization. Results of model simulations for grain sorghum (Sorghum bicolor (L.) Moench], com (Zea mays L.), and spring wheat (Triticum aestivum L.) were in reasonable agreement with field observations. The effects of plant population, fertilization level, and water stress on crop growth were implicitly accounted for in the simulations through the appropriate assignment of parameter values in empirical functions controlling leaf area appearance and senescence.

WITHIN-SEASON SIMULATION CALIBRATION SO AGRONOMY JOURNAL LA English DT Article ID INTERCEPTION; EFFICIENCY AB The accuracy of parameterized crop growth models is dependent on obtaining the proper parameter values that control the response of the model to environmental conditions. In this study, a method is described for objectively evaluating model parameters based on observations of crop growth obtained during the growing season. An iterative numerical procedure is used to systematically manipulate the values of selected parameters and initial conditions until the model simulation matches the observations of growth. Examples involving a previously-developed growth model indicate that reasonably accurate simulations can be made for three gramineous crops (grain sorghum, corn, and spring wheat) by calibrating a set of parameters and initial conditions that affect leaf area appearance and senescence. It is proposed that the effectiveness of this procedure in using infrequent growth observations and the ability to obtain these observations using non-destructive measurement techniques make this modelling procedure feasible for use in practical agricultural applications.

A very important aspects of crop yields, and societal adjustments to environmental changes, may well be altered year-to-year stability in yields. Simulations for three locations in the Midwest with mechanistic growth models for maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] showed important species differences in projected yield stability. Maize yields under global environment changes were approximately equal to current levels and the year-to-year yield variability was unchanged. Soybean, however, had higher mean yields under changed global environments as compared to the current environment, and there was substantially greater year-to-year variability under possible future environments. This disparity among maize and soybean in mean yield changes and stability across years may have important consequences on crop management and stabilization of food and feed supplies.

Plants of a parental genotype (cv. Sparkle) and a functional iron-deficiency mutant genotype (E107) were grown hydroponically with or without supplemental iron. Iron(III) reductase activity was visualized by placing the roots in an agarose matrix containing 0.2 mm Fe(III)-ethylenediaminetetraacetic and 0.3 mm Na2-bathophenanthrolinedisulfonic acid (BPDS). Red staining patterns, resulting from the formation of Fe(II)-BPDS, were used to identify iron(III)-reducing regions. Iron(III) reduction was extensive on roots of E107 as early as d 7, but not until d 11 for -Fe-treated Sparkle. Roots of +Fe-treated Sparkle showed limited regions of reductase activity throughout the period of study. For secondary lateral roots, iron(III) reduction was found for all growth types except + Fe-treated Sparkle. Treating Sparkle plants alternately to a cycle of iron deficiency, iron sufficiency, and iron deficiency revealed that reductase activity at a given root zone could be alternatively present, absent, and again present. Our results suggest that for Pisum roots grown under the present conditions, iron-deficiency stress induces the activation of iron(III) reductase capacity within 2 d.

Differentiation among ponderosa pine populations was detected for a diverse assortment of variables that included patterns of shoot elongation, measures of growth potential, winter and spring freezing damage, and leaf characteristics. Multiple regression models accounted for as much as 85% of the variance among populations and described complex clines that were dominated by elevational and latitudinal effects. Although P. ponderosa, P. arizonica, and P. engelmannii were readily differentiated, the performance of progenies from one population suggested introgression primarily involving P. ponderosa and P. arizonica but also implicating P. engelmannii.

To determine the identity of such coccidia obtained from human tissues and other sources, we compared riboprints (through restriction enzyme analysis of the polymerase chain reaction [PCR]-amplified small subunit rRNA gene) of the following protozoa: the RH and ts-4 strains of T. gondii, lines OH3 and S11, which are two recently isolated T. gondii-like parasites from Brazil, Neospora caninum, Sarcocystis species, and the malarial parasite Plasmodium berghei. In addition, the protozoan genomes were examined by PCR for homologs of surface antigen genes of T. gondii, and by Southern hybridization to the heterologous rRNA gene probe pSM 389. Strains OH3, S11, ts-4, and RH shared identical riboprints, and OH3, S11, and ts-4 have p22 and p30 surface antigen gene structures similar to RH. In contrast, riboprints for N. caninum and T. gondii differ with respect to Dde 1 sites, and moreover, their genomes vary significantly from one another at both the p22 and p30 gene loci. The riboprints of Sarcocystis and P. berghei differ markedly from T. gondii and N. caninum and from each other. Bam HI pSM 389 restriction fragment length polymorphisms differentiate ts-4 from RH, OH 3, and S11. Our results confirm that OH3 and S11 are indeed T. gondii, but that N. caninum and T. gondii are likely to be separate species, thereby resolving previous uncertainties concerning the identity of these parasites. Together, the variation in riboprints and surface antigen gene structure reflects the phylogenetic diversity among these coccidia, and in addition, confirms the value of riboprinting in the identification of apicomplexan parasites such as T gondii.

A rabbit-origin capture antibody and a mouse-origin detection antibody combined with biotin-avidin amplification were used for the assay. The antigen-capture ELISA could not detect virus directly from the blood of infected sheep because of low virus titer. To enhance detection, virus from infected blood was amplified in cell culture. Virus could then be detected from cell culture supernatant fluids, using the ELISA. This amplification step increased the sensitivity of the assay comparable to that of assays performed in cell culture measuring cytopathic effects. The ELISA procedure was specific for BTV and did not mistakenly identify the antigenically related epizootic hemorrhagic disease virus. The antigen-capture ELISA permitted indirect quantitation and identification of BTV from the blood of infected sheep.

Russet Burbank and A082260-8 potatoes were grown on Owyhee silt loam at the Malheur Experiment Station, Ontario, Oregon. Potatoes were subjected to a single episode of transient water stress by omitting furrow irrigation in either late June, july, or in early August of 1988 and 1989 to examine variety differences in the short term effects of water stress on changes in solids and reducing sugars in tuber stem ends. Irrigation was managed to maintain soil water potential above -65 kPa at 20 cm depth during tuber initiation through bulking except during transient stress when the soil water potential reached -82 to -110 kPa. Tuber samples were taken from plots and minimally stressed check treatments before stress, at the peak of stress, two weeks after the transient stress period, and after harvest. Tubers were sectioned longitudinally and the percent solids and reducing sugars were determined for samples from the tuber stem end, center, and apical end. Longitudinal tuber strips were fried after harvest to determine fry color. Tuber stem-end fry color did not darken in A082260-8 potatoes subjected to water stress. The line A082260-8 had higher stem-end solids and lower stem-end reducing sugars than Russet Burbank. Neither variety responded to transient water stress or recovery from transient stress with an immediate increase in reducing sugars in any tuber part. Reducing sugars were elevated in harvested tubers, particularly in the stem-ends of Russet Burbank potatoes subjected to water stress. Increases in tuber reducing sugars related to transient water stress were not found during the stress period or immediately after stress, but were present in harvested tubers.

In each of two years, three maize hybrids (A632 x LH38, early-maturing; B73 X Mol 7, medium-maturing; B73 X Pa91, late-maturing) were grown in three replications at plant densities of 4.9. 6.9 or 8.9 plants m-2. In Year 2, the F2 generation of the hybrids was grown under conditions similar to those for the F1 generation. Plants were harvested at physiological maturity and 28 days after physiological maturity. Grain and stover were separated for determination of the grain-to-stover ratio and stover yield. Stover was analyzed as either forage or silage prepared in polyethylene bags. The early-maturing hybrid had a higher grain-to-stover ratio, higher stover in vitro digestible dry matter (IVDDM) concentration and lower stover concentrations of acid detergent fiber (ADF) and acid detergent lignin (ADL) than the other hybrids. Plant density did not affect either grain-to-stover ratio or stover IVDDM concentration. Maize harvested 28 days post-physiological maturity had a higher grain-to-stover ratio, higher stover concentrations of neutral detergent fiber (NDF), ADF and ADL. and lower stover concentrations of IVDDM, crude protein and total nonstructural carbohydrates than maize harvested at physiological maturity. Silage produced from stover harvested at physiological maturity had a higher lactic acid concentration than when harvested 28 days after physiological maturity. F2 generation maize had a lower grain-to-stover ratio, lower stover ADF concentration and higher stover crude protein concentration than F1 generation maize. Stover IVDDM concentration from the F2 generation was higher than that from the F1 generation in unensiled forage, but lower than that from the F1 in silage. Although there were no differences in the proportions of ADF and ADL in the NDF of stover forages or silages from F1 generation maize. proportions of ADF and ADL in the NDF were greater in stover silages than in stover forages from F2 generation maize. Concentrations of ADF and ADL in stover forage and the concentrations of ADF, ADL and NDF in stover silage were significant (P<0.10) variables in stepwise regressions predicting IVDDM concentration. These results imply that stover IVDDM concentration is primarily affected by differences in cell-wall concentrations and composition that are unrelated to grain-to-stover ratio.

Queen cells in the center of the hive's broodnest were maintained at significantly higher temperatures and bad a greater chance of emerging than queen cells located on the periphery. Temperatures around cells from which queens emerged fluctuated by <10-degrees-C, even though ambient temperatures had a range of >25-degrees-C. The average temperatures around cells from which queens emerged were 32.3-34.9-degrees-C; lower averages occurred during the winter trials. Queens took an average of 15.4-17.4 d to develop. The central brood area of a colony had a significantly higher temperature with a narrower range than around any queen cell. The base temperature for degree-day accumulation during the postcapping interval for the queenline in this study was 20.9-degrees-C, and queens required an average of 98.1 DD20.9 (range, 80.0-115 DD20.9) to complete the postcapping stage.

We previously reported the development of monoclonal antibodies (MAb) to ferric pseudobactin, the siderophore of plant-growth-promoting Pseudomonas strain B10. One of these MAb reacted less strongly to pseudobactin than to ferric pseudobactin. The MAb reacted to Al(III), Cr(III), Cu(II), and Mn(II) complexes of pseudobactin at a level similar to the level at which it reacted to ferric pseudobactin and reacted less to the Zn(II) complex, but these metals would make up only a small fraction of chelated pseudobactin in soil on the basis of relative abundance of metals and relative binding constants. Fourteen-day-old barley plants grown in limed and autoclaved soil were inoculated with 10(9) CFU of Pseudomonas strain Sm1-3, a strain of Pseudomonas B10 Rif(r) Nal(r) selected for enhanced colonization, and sampled 3 days later. Extraction and analysis of the roots and surrounding soil using the MAb in an immunoassay indicated a concentration of 3.5 x 10(-10)) mol of ferric pseudobactin g-1 (wet weight). This is the first direct measurement of a pseudobactin siderophore in soil or rhizosphere samples.

At high manganese levels, MnP is induced, and LiP is repressed. At low Mn levels, MnP is repressed, and LiP is induced. Organic acid chelators are very important in attaining LiP repression with high Mn. Both mineralization and lignin depolymerization are regulated by manganese in the presence of organic acid chelators. As long as the chelators keep Mn(II) and Mn(III) in solution, repression is observed, but eventually, dismutation reactions cause the formation and precipitation of Mn(IV) as MnO2. Repression is immediately relieved, and depolymerization and mineralization proceed at a high rate.

The results suggest that while both farmers and processors do benefit from the programme, processors benefit proportionately more than farmers, receiving nearly three times the relative return of farmers from the effects of the programme. This observed outcome is a function of the joint nature of the products being produced (soybean meal and oil) by processors and the relative less importance afforded to soybean oil in the production process. In an absolute sense, however, the returns to soybean farmers are substantially greater than those to processors, being a function of the magnitude of the price of soybeans relative to the crushing margin.

This rotation also will be the most efficient option, by maintaining a profitable level of crop production irrespective of the ratio of the nitrogen fertilizer price and the corn price. Using rotation on cropland with a high potential for leaching will have a smaller compliance cost relative to that found when -the cropland has moderate leaching potential.

Air quality at the mountain forest location was characterized by high levels of nitric acid (up to 18 ppb) and the phytotoxic peroxyacyl nitrates PAN (up to 22 ppb) and PPN (up to 5 ppb). Alkyl nitrates were below our detection limits of 0.05-0.5 ppb. The (PAN + PPN)/NO2 ratios varied substantially (range 0.03-2.27) and were generally large, with typical 24-h averages of 0.19-0.50. Diurnal variations of the (PAN/PPN)/NO2 ratio exhibited both nighttime and daytime maxima reflecting diurnal variations in PAN (and PPN) thermal stability and photochemical production rates, respectively. Organic nitrogen-containing oxidation products (PAN + PPN) were more abundant than inorganic nitrate (HNO3 + NO3-), with in average organic/inorganic concentration ratio of 2.5 (daytime ratio 1.0; nighttime ratio 3.7). The four oxidation products PAN, PPN, HNO3 and NO3- together accounted for 0.26 of the total reactive nitrogen. The results are discussed with respect to diurnal and seasonal variations and in terms of NO2 atmospheric oxidation pathways. Deposition fluxes and velocities to ponderosa pine have been measured for inorganic nitrate and for ammonium and have been compared with those obtained at other mountain forest locations.

Microplots were established within a rice bay drill-seeded with the Texmont rice cultivar and CH4 fluxes were measured over the main rice cropping season. Methane emissions over the 77-day sampling period were approximately 230, 240, 260, 290, 310, and 360 kg CH4 ha-1 from the calcium carbide, Na2SO4-rate II, Na2SO4-rate I, (NH4)2SO4, dicyandiamide, and urea (control) treatments, respectively.

One of the many functions of interferons is the induction of the 2',5'-oligoadenylate (2-5[A]) system, which is involved in cell division and selective degradation of mRNA. The present study focused on the cellular changes of 2-5(A) synthetase in bovine endometrium during the estrous cycle and early pregnancy. Ability of recombinant bTP-1 to stimulate activity of the enzyme in uterine cells throughout the estrous cycle was also evaluated in vitro. Surface epithelium, glandular epithelium, and stroma were enzymatically separated in cows on Day 5, 10, 15, or 18 postestrus and on Day 1 5 or 18 of pregnancy. Cell samples were lysed and frozen for determination of the endogenous cellular content of 2-5(A) synthetase. Additional cells obtained during the estrous cycle were cultured and treated with increasing doses of recombinant bovine interferon alpha (rbIFN-alpha) or recombinant bTP-1 (rbTP-1). During the estrous cycle, 2-5(A) synthetase was greatest on Day 5 and declined approximately 10-fold by Day 15 (p < 0.01). Cellular content of 2-5(A) synthetase was similar among all three endometrial cell types. In the gravid horn of pregnant animals, presence of a conceptus significantly increased (p < 0.01) 2-5(A) synthetase in all endometrial cell types compared to levels on Days 15 and 18 of the estrous cycle. On Day 18, levels of 2-5(A) synthetase were 30-fold greater (p < 0.01) in epithelium (surface and glandular) from pregnant cows compared to that from cyclic cows. Stromal content of 2-5(A) synthetase increased 10-fold (p < 0.01) in pregnant compared to cyclic cows. In cultured uterine cells, between 1 and 10 U/ml of rbTP-1 or rbIFN-alpha stimulated 2-5(A) synthetase in all endometrial cell types from Day 5, 10, and 15 cyclic cows. Endometrial cells cultured from Day 18 of the estrous cycle had higher 2-5(A) synthetase levels than native cells, indicating that these cells differentiated during the 7-10 days of culture. These results indicate that the conceptus directly stimulates the endometrium to increase the activity of 2-5(A) synthetase at the time of maternal recognition of pregnancy (Day 15), and that the observed increase in 2-5(A) synthetase is more pronounced in the epithelium than in the stroma.

Gilts bred at estrus (Day 0) were laparotomized on Day 4, and the uterine horn ipsilateral to the ovary with the most ovulations was ligated midway between the uterine tip and uterine bifurcation to create a crowded and a roomy uterine environment. On Day 25 (n = 7) or 35 (n = 6), gilts were killed and the reproductive tract was dissected from each. Each placenta and fetus was weighed, and a sample of endometrium adjacent to each placenta was collected. Within each uterine environment, tissues (500 mg) from the heaviest and lightest (by weight) placentae and adjacent endometrial tissue were cultured for 24 h at 37-degrees-C in 15 ml Minimal Essential Medium having 0.1 times the normal amount of leucine plus 50 muCi H-3-leucine. Aliquots (2 ml) of dialyzed medium were subjected to two-dimensional PAGE and fluorography to examine proteins with molecular weight ranges of approximately M(r) 20 000-130 000, and a further aliquot was subjected to SDS-PAGE to examine low molecular weight proteins (M(r) 2000-20 000). In addition, endometrium (200 mg in duplicate) adjacent to the heaviest and lightest placentae within each uterine environment was incubated for 4 h in 5 ml MEM plus 1 muCi H-3-thymidine to measure DNA synthesis. After culture, H-3-thymidine incorporation and total DNA were determined. Fetal survival in the crowded uterine environment decreased (p < 0.05) on Day 35 compared to Day 25. On both days, the heaviest and lightest placentae from the crowded uterine environment weighed less (p < 0.01) than the heaviest and lightest placentae from the roomy uterine environment. The fetuses associated with the heaviest and lightest placentae from the crowded uterine environment also weighed less (p < 0.05) than fetuses associated with the heaviest and lightest placentae from the roomy uterine environment. Nondialyzable radioactivity in medium per gram of tissue cultured from placental cultures decreased (p < 0.05) and from endometrial culture increased (p < 0.05) between Days 25 and 35. Placental secretion of a protein with M(r) 46 000, pl 5, decreased between Days 25 and 35. Endometrial secretion of three proteins (M(r) 35 000, pI 6.2; M(r) 25 000, pI 4.9; and M(r) 14 000, pI unknown) increased, and secretion of three other proteins (M(r) 24 000, pI 6.5 doublet; M(r) 22 000, pI 7.5, and M(r) 7000, pI unknown) decreased from Day 25 to Day 35 of pregnancy. Endometrial H-3-thymidine incorporation per microgram of total DNA decreased (p < 0.1) between Days 25 and 35 and was also less (p < 0. 1) for endometrium adjacent to the lightest placentae within each uterine environment than for endometrium adjacent to the heaviest placentae. The amount of uterine space available to conceptuses had no detectable effect on endometrial H-3-thymidine incorporation or endometrial protein secretion. Placental secretion of two proteins (M(r) 36 000, pI 4, and M(r) 46 000, pI 4) was increased (p < 0.05), and secretion of another protein (M(r) 46 000, pI 5) was decreased when the amount of uterine space available decreased. These results indicate that the amount of uterine space available to conceptuses affects placental protein secretion on Days 2 5 and 3 5 of pregnancy.

To establish a model system for investigations of the mechanisms involved in these actions, we examined the effects of individual and combined treatment with PGE2 and PGF2alpha on basal and ovine LH-stimulated progesterone secretion during long-term incubations conducted with and without supplemental homologous low-density lipoprotein (IDL) as substrate. Effects of both PGE2 and PGF2alpha were concentration- and time-dependent and were further influenced by the presence of LDL and/or LH in medium. Neither of the prostaglandins exerted any significant effect before 48 h in culture, but distinctly different patterns of response to PGE2 and PGF2alpha emerged thereafter. Low, but not high, concentrations of PGE2 increased progesterone secretion in the absence of LH, whereas PGF2alpha (alone and in combination with PGE2) inhibited progesterone production in all medium formulations. The transcriptional inhibitor actinomycin effectively blocked the actions of PGF2alpha but had no effect on response to LH or PGE2. These data demonstrate that both the putative luteotropic actions of PGE2 and the potent, luteolytic effects of PGF2alpha in vivo can be reproduced in long-term cultures of ovine luteal cells in vitro, and they suggest that the mechanism of PGF2alpha-induced luteolysis may involve new protein synthesis.

Prior to the passage of Hurricane Hugo in September 1989, the watersheds had a total vegetative biomass of 301 tons/ha, 75 percent of which was aboveground. The total nutrient content of this vegetation was 907, 49, 644, 653, and 192 kg/ha for N, P, K, Ca, and Mg, respectively and varied with topographic setting. Concentrations per unit dry weight of P (0.16), K (2.49), Ca (2.13), and Mg (0.62) in aboveground vegetation were similar to other steepland tropical forests, while the concentration of N (2.9) was greater. Following the passage of Hurricane Hugo, the standing aboveground biomass was reduced to 113 t/ha and the aboveground nutrient content of the forest was reduced 45 to 48 percent.

Over 60 percent of all stems and basal area of tabonuco occurred in unions, dumps of trees interconnected by root grafts. Self and intraspecific grafting were extensive, while interspecific grafting was not common in tabonuco trees. Seedlings and saplings did not show any grafting, probably because of their size or age. Grafted trees were taller and had a smaller crown/DBH ratio. Hurricane damage was significantly higher in isolated individual tabonuco trees than those in unions. Weak relationships between diameter class, area, and size of union, and inter-tree distances and the sum of the trunk circumferences of the two nearest neighbors suggested that a noncompetitive force such as root grafting was more important than competitive forces in maintaining the unions of tabonuco, and thus the forest community. A conceptual model of the costs and gains of tabonuco in unions is presented. C1 RUTGERS STATE UNIV,NELSON BIOL LAB,DEPT BIOL SCI,PISCATAWAY,NJ 08855.

Within a given forest type, fruit fall varied spatially and seasonally. A palm (Prestoea montana) flood plain forest averaged 560 kg/ha/yr and individual palm fruit mass changed from season to season. Lower montane wet, or tabonuco (Dacryodes excelsa), forest had a low rate of fruit fall (332 kg/ha/yr) and strong seasonal pulses in both space and time. Fruit fall was higher in secondary forests (820 kg/ha/yr) and plantations (1418 kg/ha/yr) than in mature tabonuco forests that normally occur in those sites. Fruit fall in the upper montane, or colorado (Cyrilla racemiflora), forest averaged 263 kg/ha/yr. Somewhere in the LEF there always appears to be a stand at peak mte of fruit production. Fruit fall data are used to reduce a previous estimate of forest carrying capacity for the endangered Puerto Rican parrot, Amazona vittata, from 5 1,000 to 2000-38,000 birds.

Although the foot regions of the two Folioceros species studied are similar in some respects to those of other species of Anthoceros (e.g., presence of a palisade layer), the presence of small (2-3 nm periodicity) protein crystals and the close intermingling of gametophytic and sporophytic tissues are distinct from most of the Anthoceros species. Based on our findings, we conclude that Folioceros should be separated from Anthoceros at the subgeneric level. C1 KYOTO UNIV,FAC AGR,APPL BOT LAB,KYOTO 606,JAPAN.

(lesser grain borer, Coleoptera: Bostrichidae is a major pest of stored grain in the United States, Australia, and most other warm regions of the world. It has rarely been detected in Canadian grain, until recently. To determine the distribution of R. dominica in western Canada, Lindgren multiple-funnel traps baited with R. dominica aggregation pheromones were placed near grain elevators, feed mills, and farms. Rhyzopertha dominica was found flying outside grain-handling facilities in all Prairie Provinces in 1990 and 1991, with thousands collected in Manitoba, hundreds in Alberta, and less than 100 in Saskatchewan. A few R. dominica were caught in Vancouver and Thunder Bay. None were caught in the traps placed beside two grain elevators in southern Ontario. In Alberta and Saskatchewan, the locations with R. dominica were mainly in the south. In Manitoba, the total number of R. dominica caught at each location was higher in the south than in the north. Rhyzopertha dominica were caught as early as 15 May and as late as 18 September, with the peak numbers for a given location occurring between July and September. No difference in the total number of R. dominica caught per year was found among farms, feed mills, or grain elevators in 1990 or 1991. Sampling of stored grain on three farms showed that two of the eight bins sampled had R. dominica. The possible origins of the R. dominica (importation of infested grain, wind-borne migration from the United States, or an established Canadian population) are discussed.

The amount of (Z)-11-hexadecenal, the major component of the pheromone of both species, increased during the first 60 min after injection of PBAN then leveled off and declined in H. virescens. In H. subflexa, the amount of this aldehyde increased during the first 120 min and declined after 240 min. Studies indicated that extracts of the brain-subesophageal ganglion complex that did not contain neurally produced biogenic amines induced production of as much pheromone as did homogenates containing these compounds. Dose-response studies indicated that the optimal dose of synthetic PBAN for induction of pheromone during a 60-min incubation was 5.0 pmol. In vivo maintenance of pheromone production required continuous stimulation of the pheromone gland.

Aboveground vegetation cover was assessed by species in twelve 5-M2 plots. Seed rain was sampled during the 1988, 1989, and 1990 growing seasons with pitfall traps, and the soil seed bank was sampled in fall 1989, spring 1990, and fall 1990. The seed rain (filled seeds) on the borrow area ranged from 7730 to 14 009 seeds/m2 and was higher than that found on other alpine sites; that on the Geum turf ranged from 3375 to 6179 seeds/m2 and was similar to that for other alpine sites. Although highly variable among dates on the borrow area, the seed banks were similar to those of comparable alpine sites. Seed bank density ranged from 1980 to 6003 seeds/M2 on the borrow area and from 3202 to 4647 seeds/m2 on the Geum turf area. The Geum turf area had higher vegetation cover than the borrow area (87 vs. 25%) and higher numbers of species in the aboveground vegetation, seed rain, and seed bank. Relationships among the aboveground vegetation, seed rain, and seed bank were largely determined by the disturbance characteristics of the different sites and the life-history strategies of the dominant species. Medium-lived species, primarily grasses, with high production of small and compact seeds had colonized the borrow area. Despite establishment of other species, 35 years after disturbance the medium-lived species still dominated the aboveground vegetation, seed rain, and seed bank. Species abundances in the three different components were all highly correlated. In contrast, on the Geum turf area there were no correlations among the aboveground vegetation, seed rain, or seed bank. Long-lived forbs that produced low numbers of relatively large seeds dominated the aboveground vegetation and persisted on the area primarily in the vegetative state. The same medium-lived species that dominated the borrow area had the highest abundance in the seed rain on the Geum turf area and appeared to persist by colonizing small-scale disturbances caused by gopher burrowing. Short-lived species with small, long-lived seeds existed on the site primarily through a highly persistent seed bank. The relationships among the aboveground vegetation, seed rain, and seed bank on the Geum turf and borrow areas are compared with those observed for more temperate systems following disturbance.

One-half of the seedlings were inoculated with a mixture of equal numbers of spores of six vesicular-arbuscular mycorrhizal fungi at transplanting. Dry weights of plants and component parts were determined. Percent colonization of roots was determined microscopically. Growth response and mycorrhizal dependence were calculated. However, no mycorrhizal dependence was observed in Triticum monococcum PI 266844 and PI 355520 (A genome), Aegilops speltoides 1773 (S(B) genome), or in the AB genome ancestors Triticum carthlicum 2825, Triticum polonicum 2808, Triticum dicoccum 1165, Triticum pyramidale 2809, Triticum orientale 2805, Triticum paleocolchicum 2807, and Triticum persidum 2811 and 2812. Mycorrhizal dependence in the D genome ancestors was more variable. Triticum tauschii var. typica accessions 1649, 1691, 2378, 2448, 2492, 2495, 2528, 254 1, and 2567 lacked dependence, whereas T. tauschii var. meyeri 2529 and var. strangulata 2377 and 2452 were dependent on mycorrhizal symbiosis. The spring wheat cultivars Chinese Spring 3008, Spelta 2603, Pavon 76 2980, and Norin 29 3025 and the winter wheat cultivars TAM 200, Wrangler, Saluda, and Karl were not dependent on mycorrhizae, whereas winter wheat cultivars TAM 107 and Century were dependent. When these data are synthesized with previously tested ancestors, landraces, and cultivars, it appears that both dependent and nondependent diploid ancestors with the A, S(B), and D genomes existed, but dependence was lost in tetraploid ancestors. Since no dependence on mycorrhizae has been demonstrated in any AB genome ancestors, the presence of dependence in modern cultivars of the hexaploid ABD genome is probably derived from the D genome. The consistent dependence of wheat cultivars released before 1950 suggests that modern breeding practices have reduced dependence on mycorrhizal symbiosis. The implications of having mycorrhizal colonization in the absence of mycorrhizal dependence (benefit) are discussed. C1 USDA ARS,MANHATTAN,KS 66506.

After 18 weeks of exposure th ozone of concentrations as high as 170 ppb (nonfiltered air + 150 ppb ozone) in an 8-h period, net photosynthesis of grafted red spruce was reduced by ozone. Significant reductions were not observed until September 1988. Mature and juvenile scions grown in nonfiltered air + 150 ppb ozone showed 29 and 40% reductions, respectively, in mean seasonal net photosynthesis (mg CO2.g dry wt.-1.h-1) compared with those plants grown in nonfiltered air. Scion age had a significant effect on net photosynthesis and stomatal conductance. Net photosynthesis (mg CO2.g dry wt.-1.h-1) and stomatal conductance were 38 and 47% higher, respectively, in juvenile than in mature scions. Chlorophyll a and total chlorophyll concentration of juvenile scion needles were significantly reduced 19 and 24%, respectively, when grown in nonfiltered air + 150 ppb ozone compared with that grown in charcoal-filtered air (p < 0.01). Mature scions had significantly more chlorophyll a than juvenile scions in October 1988. Current-year needles collected from mature scions had significantly greater mass, length, one-sided projected surface area, width, and thickness than juvenile scions. Mature scions had significantly lower needle numbers per centimetre branch than did juvenile scions. No differences in specific leaf weight were observed. Mature scions had less ozone uptake than did juvenile scions. C1 UNIV MAINE,DEPT FOREST BIOL,ORONO,ME 04469. RP REBBECK, J (reprint author), US FOREST SERV,NE FOREST EXPT STN,DELAWARE,OH 43015, USA.

Principal tree species at West Twin Creek are Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.) Sarg.), Pacific silver fir (Abies amabilis (Dougl.) Forb.), western red cedar (Thuja plicata D. Don), and Sitka spruce (Picea sitchensis (Bong.) Carr.). At Hoh Lake they are Pacific silver fir, mountain hemlock (Tsuga mertensiana (Bong.) Carr.), and Alaska cedar (Chamaecyparis nootkatensis (D. Don) Spach). In 1985 stem densities for trees >5 cm DBH averaged 476 and 489 ha-1 in the upper and lower West Twin Creek watershed, respectively, and 508 ha-1 at Hoh Lake watershed. Stem densities at both sites declined 3-5% from 1985 to 1990. Western hemlock and Pacific silver fir were the dominant species at West Twin Creek and Hoh Lake, respectively. From 1985 to 1990 the annual mortality rate was 0.8% at West Twin Creek and 0.9% at Hoh Lake. Pacific silver fir had the highest mortality rate. No Douglas-fir or western red cedar trees died. The primary causes of mortality were as follows: suppression-unknown, diseases, insects, and windthrow. In 1985 basal areas were 77, 87, and 94 m2.ha-1 in the lower and upper West Twin Creek watershed and Hoh Lake watershed, respectively. There was a 5% increase and a 1% decrease in basal area from 1985 to 1990 in the lower and upper West Twin Creek watershed, respectively, and a 4% decrease at Hoh Lake. Western red cedar, Douglas-fir, and western hemlock increased in basal area, while the other species declined. C1 US FOREST SERV,PACIFIC NW RES STN,FORESTRY SCI LAB,OLYMPIA,WA 98502.

In experiment 1 we measured rumen particle-size distribution, rumen fill, and particle and liquid passage rates of animals fed three diets varying in quality (chopped pea, alfalfa, and wheat hays). In experiment 2, similar measurements were obtained on elk fed alfalfa hay ad libitum or at restricted intake levels. Rumen characteristics and passage rates of particles and liquids were similar for animals consuming alfalfa and pea hays. Intake, rumen dry-matter concentration and fill, and liquid passage rate were significantly lower when animals consumed wheat hay. Few significant differences in rumen characteristics or passage rates were found between animals fed alfalfa ad libitum or at restricted levels. Rumen liquid volume and dry-matter fill were related linearly to intake (r2 = 0.98 for both) in deer and elk fed alfalfa and pea hays. However, liquid volume and dry-matter fill of elk fed wheat hay and alfalfa at restricted levels were higher than the deer-elk interspecific regression, indicating an adaptive ruminal response. We concluded that rumen function was adaptive to both diet quality and availability, but that the response likely was subject to the limitations imposed by food characteristics and the inherent limitations of rumen structure and function.

The objective was to assess the variation in levels of tocols among genotypes and locations. Significant genotype differences existed for most tocols in both species. Total tocol concentrations for genotypes ranged from 19 to 30 mg kg-1 for oats and from 42 to 80 mg kg-1 for barley. Location differences were significant for oats but not for barley. Only a small percentage of the variance was associated with the interaction of genotype and location. Alpha-Tocotrienol and alpha-tocopherol were the predominant tocol isomers in both species; beta- and gamma-tocotrienol were also present in significant amounts in barley. The major isomers of barley, but not of oats, were generally positively correlated with each other. The data indicate the feasibility of attempting to increase tocol concentration in these crops by hybridization and selection. That could lead to food products that might lower serum low-density-lipoprotein cholesterol, a risk factor for cardiovascular disease. C1 ADV MED RES,MADISON,WI.

The chain-length distributions of amylopectins were determined by an enzymatic-chromatographic method. Each genotype exhibited distinctive GPC elution patterns of its native and isoamylase-debranched starches and distinctive morphology as noted by SEM. The amylose-extender (ae), dull-1 (du1), and sugary-1 (sul) genes were associated with increased amounts of amylose and intermediate fractions compared with normal starch. The waxy (wx) gene was epistatic to other genes relative to the accumulation of amylopectin, which was consistent with work done elsewhere. The discrepancy in amylose percentage determined by GPC and IA in some genotypes may have resulted from the presence of a large amount of intermediate materials in those genotypes, which could not always be distinguished from amylose by the IA method. For example, in ae starch, most of the intermediate materials were measured as amylose by the IA procedure, whereas in du1, ae brittle-1 (bt1), and ae du1 starches, most of the intermediate materials were excluded from IA measurements. The intermediate fractions from each genotype in the GPC elution profiles also differed from each other, suggesting differences in molecular weight and/or branching. The proportions of long B chains and the average chain length of amylopectins were increased when the ae gene was present. In contrast, the dul gene decreased the proportions of the long B chains of amylopectins. The mutants containing the ae gene showed low degrees of branching in amylopectin; mutants containing the du1 and/or su1 genes had high degrees of branching. Genetic background played a major role in determining the fine structure of starch components. The effects of interactions between recessive mutant genes on the structures and morphology of different starch genotypes were evident.

Those identifications were made during milling. The resulting flours were tested for starch damage, presence of the 15-kDa starch granule protein, and sugar-snap cookie spread. The 19 lines derived from Falcon, 10 hard and nine soft, had acid-polyacrylamide gel electrophoresis (A-PAGE) patterns of gliadins identical to each other and to those of Falcon. Likewise, the 11 lines derived from Heron, six hard and five soft, had A-PAGE patterns identical to each other and to those of Heron. As expected, the A-PAGE patterns were genotypic and not related to the hardness or softness characteristic. Milling and baking parameters correlated highly with classification of the flours as being hard or soft, rather than with classification according to the flour's gliadin (A-PAGE) pattern.

These physicochemical properties included blue value (BY), maximum absorbance wavelength (lambda(max), limiting viscosity number ([eta]), swelling power and solubility at 85-degrees-C, and percent light transmittance (%T) of starch paste at 650 nm. Pasting properties were determined by means of Brabender viscoamylography, gel strength by texture analysis, and thermal properties by differential scanning calorimetry. Amylose content was the most important structural characteristic affecting the physicochemical properties of starch. Amylose content was significantly (P < 0.01) correlated with BY (r = 0.96) and lambda(max) (r = 0.81) and was negatively correlated with [eta] (r = -0.83), %T (r = -0.88), swelling power (r = -0.86), and peak viscosity (r = -0.97). Other structural characteristics, including intermediate material content, average chain length of debranched amylopectin, and ratio of long B chains to short B chains plus A chains of amylopectin, were weakly Correlated with properties. Some significant correlations were found among properties, including BY, %T, swelling power, and peak viscosity. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT FOOD SCI & HUMAN NUTR,AMES,IA 50011.

The degree of gelatinization was determined by an objective method (differential scanning calorimetry) and by a subjective rice-grading method that yielded the percentage of translucent kernels in a given sample of parboiled rice. A linear correlation was found between the two methods for both varieties, which suggested that the grading procedure could be used to estimate the degree of gelatinization once a calibration curve was established. In addition, the degree of gelatinization, as determined by differential scanning calorimetry, was compared with head rice yield. The relationship between the two variables was nonlinear, and maximum head rice yield for both Lemont and Tebonnet was achieved when the starch was about 40% gelatinized. Our results indicate that extensive starch gelatinization (extensive parboiling) is not necessary to obtain maximum head rice yields.

On day 1 of clenbuterol feeding, the principal source of circulating L-lactate switched from portal-drained viscera to hindquarters. 4. Both net release of alpha-amino nitrogen by the portal-drained viscera and net uptake by the hindquarters decreased on day 1 of clenbuterol feeding. Over time of clenbuterol feeding, both release of alpha-amino nitrogen by the portal-drained viscera and uptake by the hindquarters increased to equal or greater than pretreatment values, respectively.

In part because of concerns over residue levels, this chemical is no longer registered for use on fruit. One approach to reducing residues is to lower the application rate. Methiocarb was evaluated on blueberries in an aviary trial at application rates of 0.6, 1.1 and 1.6 kg ha-1 and in the field at 1.1 and 1.6 kg ha-1. In the aviary trial, individually caged cedar waxwings (Bombycilla cedrorum) were not repelled by the application at 0.6 kg ha-1, but consumption of blueberries was reduced by 60% with the treatments at 1.1 and 1.6 kg ha-1. In the field trial at 1.1 kg ha-1, bird damage to blueberries in the treated plot was 57%, compared with 29.5% on the untreated plot. In the field trial at 1.6 kg ha-1, blueberry loss at 7 and 14 days post-treatment was 59% and 85% on the treated unit and 65% and 85% on the control, respectively. Methiocarb residues on blueberries decreased from 8.56 p.p.m. at 1 day post-treatment to 1.28 p.p.m. at 14 days post-treatment. The results of these trials (a) suggest that reduced methiocarb applications do not effectively control bird damage to blueberries and (b) do not support further pursuit of a new Mesurol registration for this use.

Objectives of this study were to determine the effectiveness of multiple cycles of recurrent restricted phenotypic selection ( RRPS) in improving forage yield in switchgrass and in improving in vitro dry matter digestibility (IVDMD), and to compare predicted and realized gains from selection. Six switchgrass populations were developed by selecting a base population for one cycle of low and three cycles of high IVDMD and two cycles for high yield. Half-sib progenies of parents selected from the base population for high and low IVDMD were used to estimate heritability for IVDMD by parent-progeny regression. Realized gains from selection were determined in a seeded sward trial that included the base and six selected populations. Estimated and realized heritabilities for IVDMD were 0.40 and 0.31, respectively. Predicted pins and (in parenthesis) realized gains from selection for IVDMD in grams per kilogram per cycle were - 21 (- 15) for the Low IVDMD Cycle 1, 16 (15) for the High IVDMD Cycle 1 ('Trailblazer), 14 (4) for the High IVDMD Cycle 2, and 19 (18) for the High IVDMD Cycle 3 populations. There was a low but positive genetic correlation between forage yield and IVDMD of 0.10. Forage yield was not improved by RRPS, probably because of lack of genetic variability for forage yield in the base population. It is concluded that RRPS is effective for improving IVDMD in switchgrass, but was not effective in improving forage yield in the populations evaluated, and that predicted gains exceeded realized gains from selection for IVDMD due to limited selection for traits other than IVDMD.

We investigated the possibility of using the Tassel-seed (Ts-5) mutant of maize as a model system for studies of assimilate movement into developing maize kernels. Hypodermic needles (26 gauge, 9.5 mm long) inserted under the pedicel epidermis of intact plants were used to introduce solutes into the pedicel free space. Additionally, excised tassel branches were incubated in buffered solutions containing 100 mM C-14-labeled sugars. The movement of apoplastic and symplastic fluorescent dyes as well as C-14-labeled assimilates and incubation solutions showed that Ts-5 maize provides a useful experimental system for study of the mechanism of assimilate transport into developing kernels.

Moench]. The objective of this study was to develop a laboratory method for separating and quantifying [C-14]hexose and [C-14]sucrose in numerous plant organ extracts simultaneously. The described method combines easily with available assays for [C-14]starch and [C-14]Structural components and for total fructose, glucose, sucrose, and starch. Treatment with hexokinase is followed by batch treatment with anion exchange resin. Hexose, as hexose phosphate, binds (> 95%) to the resin, and sucrose remains unbound (> 95%). Radiolabel in extracts is nearly completely recovered (99%). Determinations are reproducible (SE = 1.3%). This method was applied to identify differences in sugar metabolism between organs and among growth stages of field-grown sorghum. C1 TEXAS A&M UNIV SYST,DEPT SOIL & CROP SCI,COLL STN,TX 77843.

This study was undertaken to develop an efficient method for the production of androgenetic haploids in maize. A novel modification of the indeterminate gametophyte (ig) system was developed and the resulting frequency of androgenetic haploids investigated. The method combines the traditional genetic behavior of the ig allele with a tertiary trisomic (3 3 B-3LA) stock in a modified W23 background. Maintenance and generation of ig homozygotes are greatly simplified. The frequency of haploid generation has been elevated to as high as 8% utilizing inbreds of Lancaster heritage. The C, S, SD, Vg, ME, MY, CA, L, and Q cytoplasmic male-sterile stocks, homozygous for ig and of similar background to the tertiary trisomic stock, are also discussed. Development of a 3(ig) 3(ig) B-3Ld(Ig) tertiary trisomic stock in an improved modified W23 background should simplify the production of androgenetic haploids and facilitate the exchange of male-sterile cytoplasm into inbred lines of maize. This stock has potential use in experiments involving wide hybridizations between maize, teosinte [Zea mays subsp. mexicana (Schrader) Iltis], and eastern gamagrass [Tripsacum dactyloides (L.)

Treatment of corn (Zea mays L.) with ABA was previously shown to increase flooding survival 10-fold. The long-term effects of A.BA treatment and flooding stress on growth and productivity have not been documented. In this study, ABA-treated corn seedlings that survived a flooding stress in the laboratory were transplanted to the field and their growth and seed yield compared with those of nonflooded plants. While ABA treatment had no effect on nonflooded plants, ABA-treated plants recovered from the flooding stress more quickly than plants not receiving A.BA. At 4 wks after transplanting, ABA-treated, flooded plants were as tall as nonflooded plants (56.03 +/- 1.85 cm), while flooded plants that received no ABA pretreatment were 22% shorter (43.70 +/- 2.3 cm). Abscisic acid treatment and flooding did not have any long-term effects on plant senescence. At the end of the growing season, no differences were detected in leaf chlorophyll content among the treatments. Grain yields of the surviving plants were also similar among all treatments. According to the results, A.BA treatment at 100 muM improved the flooding survival of corn seedlings 10-fold, without any deleterious effects of subsequent growth, senescence, or productivity of corn plants. This research contributes to the understanding of the physiological mechanism by which ABA enhances the flooding tolerance in corn.

Comparisons of distances between the ash whitefly, Siphoninus phillyreae, and two biotypes (''A'' and ''B'') of the sweetpotato whitefly, Bemisia tabaci, based on sequence analysis of genes for 18S rRNAs (rDNAs), were equivalent to the distances represented by the 16S rDNAs of their respective endosymbionts. This finding indicates that evolutionary divergence in whitefly hosts and their endosymbionts is congruent. The nucleotide sequences of the 18S rDNAs and endosymbiont 16S rDNAs indicate the two biotypes of B. tabaci are the same species.

Currently the problem is under attack on three fronts: 1) prevention and treatment of malnutrition, 2) implementation of oral rehydration and rapid reintroduction of feedings, including staple foods, in the immediate postrehydration period, and 3) less successfully, prevention of infection. In some countries of the developing world, the major concern in the malnutrition-diarrhea-infection cycle is still survival. Investigators today, however, are increasingly addressing the long-term effects on the height and neurodevelopment of survivors.

The site had been excluded from fire for approximately 40 years, and the characteristically open longleaf pine (Pinus palustris) savannah had developed a thick midstory of evergreen scrub oak species. Shading and litter accumulation had resulted in a sparse ground cover with only a weak component of the once ubiquitous wiregrass (Aristida stricta). Our primary goal was to determine hexazinone rates suitable for releasing understory herbaceous vegetation (especially wiregrass) from midstory oak suppression. At 1 year post-treatment, proportion mortality of midstory oaks increased with increasing hexazinone rate (P < 0.05) and decreased with increasing oak diameter. Oaks with diameters > 14 cm experienced no mortality. Proportional change in understory cover by oaks also decreased with increasing hexazinone rate, while wiregrass cover increased with increasing hexazinone rate. Wiregrass biomass responded to treatment rate in a nonlinear fashion, possibly due to differences in top-kill. Treatment responses for woody non-oak species, and forbs could not be detected.

(Lepidoptera: Lymantriidae), is a dynamic process in which the response to temperature gradually changes over the course of development. No clear demarcation of diapause and post-diapause development was presumed. Rather, an initial developmental response having low thresholds and optimal temperatures was assumed to give way gradually to a response having higher thresholds and optima. With one set of parameter values, the model produced results comparable to those from experiments conducted with Russian and Japanese populations of the gypsy moth, and consistent with one set of data from North America. However, these results were inconsistent with data from other, more detailed experiments conducted with North American eggs. Changes to the model that improved the fit to the North American data were then determined. The model served to identify areas of disagreement among the published data, and to suggest experiments that will help resolve unanswered questions about diapause development in the gypsy moth.

We evaluated how calcium, magnesium, and phosphorus interacted to influence budworm fitness on artificial diets containing five different levels of the minerals. We quantified survival rates for several life stages using a three-generation bioassay. Data from the bioassay were used to estimate population growth over three complete generations. Performance of the budworm was affected by Mg (linear response for F1 generation; 0.83-1.95 mg/g tested) and P (quadratic response for P1 [parental] and F1 generations; 2.74-4.95 mg/g tested) but was largely unaffected by Ca (0.50-6.81 mg/g tested). Overall, the results suggested budworm performance is best when Mg is at low concentrations and P is at moderate concentrations, and that very high levels of Mg and P are detrimental to the budworm. On average, host trees had too much Mg and too little P for optimal response by budworms. Interactions between Mg and P imply that balances or ratios of minerals are important in budworm nutritional ecology. However, detectable effects from Mg, P, and Ca in the diets diminished as the bioassay continued into the F2 generation, and, consequently, the estimated number of larvae alive at the beginning of the F2 and F3 generations showed no relationship to concentrations of the test minerals. This result probably reflected: (1) the loss of some design points in the second and third generations of the bioassay because larvae did not survive on diets that were markedly suboptimal and (2) increased variability in the population growth response as the experiment continued into the F2 and F3 generations.

We sought to account for N2 fixation and dry deposition using a lysimeter mass-balance approach. Large sand-filled, field lysimeters were used to construct 5-yr nitrogen budgets for two N2-fixing trees, two pines, and a nonvegetated control soil. This approach is a promising and straightforward technique for quantifying otherwise difficult-to-measure fluxes. Accurate assessment of changes in N storage combined with direct measurement of N inputs in precipitation and losses from leaching allowed us to estimate fluxes. Gains of N in pine systems were greatest in vegetation and litter, overshadowing combined losses from mineral soil and leaching by about threefold. Rapid acetylene reduction in pine rhizospheres and in cultures from washed roots suggests that unexplained gains are due to associative N2 fixation. These results provide strong evidence for N2 fixation in pine systems of almost-equal-to 50 kg . ha-1 . yr-1 N. The symbiotic N2-fixing trees black locust and black alder fixed 2 and 5 times more N2, respectively, than did pines. In all systems, input in precipitation and dry deposition were relatively unimportant to the N budget. Unexplained losses of N from the nonvegetated control suggest that denitrification is an important flux. Mineral soil organic matter declined sharply and significantly in pines (20%) and even more so in the nonvegetated control (40%). Symbiotic N2-fixing trees caused a small, nonsignificant increase in mineral soil organic matter and large, significant increases in litter layer organic matter. Bulk density (0-20 cm) declined by 5% under symbiotic N2-fixing trees and increased by 5% in one pine sandbox. Correction for soil expansion or collapse did not greatly alter estimates of unexplained N or N2 fixation. Pines with rhizospheres that fix N2 at the rates we observed might be used to restore degraded land and to create silvicultural systems that are N self sufficient. We first need to better understand the microbiology, tree genetics, and soil conditions that lead to rapid N2 fixation in pine ecosystems.

(Lepidoptera: Noctuidae) by gas chromatography-mass spectrometry. In addition, trace amounts of (Z)-9-hexadecenal (Z9-16:Ald) were detected in the extracts by GC. A blend of Z11-16:Ald, Z11-16:OH and 16:Ald in a ratio of 100:6:3, as well as in combination with 0.1 or 1 part Z9-16:Ald was tested at 0.01, 0.1, 1.0 and 10.0 mug doses in a flight tunnel. In flight tunnel tests male behavioral responses elicited by 0.1 or 1.0 mug doses of the 100:6:3:1 blend were similar to those elicited by an ovipositor extract at 2 female equivalents. Deletion of Z9-16:Ald from the blend at 0.1 mug dose caused a decrease in the male response. In the field test, however, presence or absence of Z9-16:Ald did not significantly influence the number of males trapped in sticky traps with rubber septa containing 100 mug of the respective blends.

Visitor opinions on the aspects of the wilderness that have great impact on their experience can provide valuable input to selection of indicators. Cohutta, Georgia; Caney Creek, Arkansas; Upland Island, Texas; and Rattlesnake, Montana, wilderness visitors have high shared agreement that littering and damage to trees in campsites, noise, and seeing wildlife are very important influences on wilderness experiences. Camping within sight or sound of other people influences experience quality more than do encounters on the trails. Visitors' standards of acceptable conditions within wilderness vary considerably, suggesting a potential need to manage different zones within wilderness for different clientele groups and experiences. Standards across wildernesses, however, are remarkably similar. C1 US FOREST SERV,INTERMT RES STN,MISSOULA,MT 59807.

Each column had received a cap of litter-humus from either a jack pine or mixed hardwood stand, or a quartz sand (control) and was preconditioned by treatment with rainwater acidified to pH 5.4 or 4.2, applied weekly throughout the growing season for four years. C-14-labeled material was added to the commercial formulation of each product and applied at 2.24 kg (active ingredient [a.i.])/ha of hexazinone and tebuthiuron and 42.5 g (a.i.)/ha of sulfometuron methyl. Acidified rainwater was applied weekly to approximate ambient precipitation; additional water was applied on three occasions. Soil water was sampled once at 10, 20, and 40 cm, and 10 times at the 150-cm level over the 130-d post-treatment. Sulfometuron methyl apparently had dissipated by 80 d post-treatment and was not detected below 20 cm. At the 150-cm level, hexazinone and tebuthiuron were detected in leachate beginning 52 and 66 d post-treatment, respectively. Leaching of both products was affected significantly by litter-humus treatment; by amount of applied rainwater, and for tebuthiuron, by site. The lack of a humus cover increased the amount of hexazinone at 150 cm by nearly threefold and tebuthiuron by nearly fivefold. The greatest leaching occurred after high applications of water and on the four sites with the lowest pH and base saturation. The combination of soil characteristics, litter-humus treatments, and applied precipitation provides reference values for worst-case conditions likely to be encountered in the Lake states region.

Off-site movement in stream flow, leaching to ground water, and thermal combustion have been examined. Model verifications of pesticide fate and dissipation and risk analyses have been conducted using simulation models such as GLEAMS, CREAMS, and PRZM. Field study data indicate that movement is controlled by the main hydrologic pathways (e.g., surface runoff, infiltration, interflow, and leaching below the root zone). Peak residue concentrations tend to be low (<500 mug/L), except where direct applications are made to perennial streams or to ephemeral channels, and where buffer strips are not used and do not persist for extended periods of time. Indirect effects noted from the use of pesticides in forested watersheds include temporarily increased nitrate nitrogen losses, reduced sediment yields, temporal changes in terrestrial invertebrate abundance, reduced plant diversity, and changes in particulate organic matter transport in streams. Very limited cumulative effects research has been conducted. The effects of increasing watershed size on herbicide concentrations and the impact of nonforestry pesticides on fish have been examined. Analyses conducted in regional environmental impact statements indicate that the low concentrations and short persistence of forestry pesticides in surface and ground water do not pose a significant risk to water quality, aquatic biota, or human health.

Drought or excessive rainfall may seriously affect dissipation rates, routes, and the extent of movement through soil profiles. The pesticide root zone model (PRZM) is designed to predict pesticide movement in unsaturated soils within and below the plant root zone in agricultural systems. The applicability of this model to a forested watershed was tested by using on-site hydrologic data to simulate a field application of lindane. PRZM-predicted data were compared with measured residue levels and found to estimate accurately lindane movement and leaching at shallow soil depths (0-10 cm), but underestimated residue levels at deeper soil depths (40-50 cm). Model simulations were used to evaluate various insecticide and herbicide application scenarios used in pine plantation management. Results from these simulations indicate that insecticides commonly used for gypsy moth (Lymantria dispar L.) or southern pine beetle (Dendroctonus frontalis Zimm.) control either are not sufficiently persistent or are adsorbed in the soil to such an extent that they do not pose a potential groundwater contamination problem. In contrast, site preparation herbicides show a potential to leach whenever proper meteorological conditions such as rainfall prevail after application. These herbicides are persistent (t1/2 > 50), moderately adsorbed (10 > K(d) > 0.1, assuming 1.7% organic matter), and applied under conditions of reduced evapotranspiration.

One of the most critical problems is the control of seed and cone insects requiring heavy and frequent applications of insecticides. Hydrologic modeling of insecticide fate in surface water and ground water is a useful technique for evaluating the environmental fate of the applied insecticides. The GLEAMS (groundwater loading effects of agricultural management systems) model was used to evaluate the differences between fate of insecticides at four pine seed orchard sites in different physiographic regions of the southern United States. A 50-year simulation period was used. Insecticides selected for simulation were carbofuran, azinphosmethyl, fenvalerate, and permethrin. The simulations of insecticide losses in storm flow and percolate at each of the seed orchards demonstrated the importance of the time of application relative to precipitation occurrence, effective rooting depth, and soil-water conditions. Although the absolute insecticide losses may not be accurately simulated by GLEAMS, the model can predict the seasonal patterns of loss and relative loss among different insecticides likely to occur under actual seed orchard conditions.

FSCBG predicts the behavior of spray material released through nozzles into the wake of a spray aircraft (helicopter or fixed-wing), traveling through idealized atmospheric effects, penetrating a canopy and depositing on the ground. FSCBG contains simplified models for the complex flow structure behind aircraft and the mechanisms that affect the fate of aerially released material: downwind drift, evaporation, canopy penetration, and ground and canopy deposition. Model development efforts encompass the areas of spray behavior, aircraft wake effects, meteorological influences, canopy interaction, and deposition. These efforts are supplemented by model validation with field tests. The ability of the model to quantify off-target spray drift is particularly important.

The concentrations of culture ingredients: 20 g glucose l-1, 2.5 g Tastone yeast extract l-1, 7.5 g Pharmamedia l-1 are optimum for batch cultures. Initial glucose concentration determined total dry weight which was largely composed of mycelia: Pharmamedia concentration influenced the yield and rate of spore production; Tastone 154 yeast extract apparently supplied a nutritional factor which also affected the yield and rate of spore production but to a lesser extent. Batch culture with the described media yielded 6.2 x 10(7) spores per ml in three days. Studies of spore recovery, drying and storage can now be conducted with a commercial type culture medium.

Conversely, indole-3-acetic acid (IAA) and cytokinins have been reported to increase stomatal aperture and stimulate photosynthesis. Field experiments were conducted in 1990 and 1991 to determine possible correlations of concentrations of ABA, IAA, and the cytokinin, isopentenyladenosine ([9R]iP), with a decline in photosynthesis that occurs in cotton (Gossypium hirsutum L.) leaves as they age. Sympodial leaves were tagged 31 July 1990 at the first node of fruiting branches when the flower was at anthesis at that node. Photosynthesis was measured at intervals thereafter during the next 37 days as the tagged leaves became older. Mainstem leaves were selected at 4, 8, 12 and 16 nodes below the apex on 7 August 1991. Photosynthesis rates were determined in full sunlight and the leaves then harvested and analyzed for free and conjugated ABA, free and ester IAA, and the cytokinin, [9R]iP. Free ABA decreased, rather than increased, with leaf age. Although conjugated ABA increased with leaf age, it is thought to be sequestered in vacuoles and, therefore, metabolically inaccessible. [9R]iP changed little with leaf age. Ester IAA increased with leaf age and was negatively correlated with photosynthesis. Free IAA decreased with leaf age and was significantly correlated with photosynthesis. RP GUINN, G (reprint author), USDA ARS,WESTERN COTTON RES LAB,4135 E BROADWAY,PHOENIX,AZ 85040, USA.

Invasion is occurring by ''hitch-hiking'' egg masses and other life stages arriving in Florida from northern states where the gypsy moth is established. Another likely mode of invasion is the gradual diffusive spread of the established area which is moving south at about 10-20 km/yr. We predict the arrival of this spreading front in north Florida in about 2025. Warm winters in Florida present one obstacle to successful diapause in the egg stage. Gray's diapause model predicts emergence of northern eggs of about 25% in Tallahassee, 10% in Gainesville and zero further south. Comparison of laboratory data with north Florida weather is in good agreement with Gray's model as are predictions with climate-matching software (CLIMEX). Genetic selection may modify the diapause requirements if invasion occurs by gradual diffusion making establishment this way more likely. We define pest status in Florida as the occurrence of large oscillations typical of northern populations. Localized outbreak densities are likely to occur if local patches are larger than ''critical patch size'' where reproductive growth outstrips diffusive loss. If this occurs in north Florida forests, and there are strong nonlinear interactions with the forest and the natural enemies then large oscillations are likely to occur.

Live nymphs were distinguished by their ability to deposit honeydew on water-sensitive paper held in contact. With the exception of 3 detergents, all materials evaluated at 1% concentration caused greater than 85% mortality of SPWF nymphs compared to applications of water.

Furthermore, the excess portion of wood that was removed from the edging and trimming process contained a large percentage of clear wood. In light of rising costs and increasing environmental concerns, the option of producing furniture parts from unedged and untrimmed boards is explored. This research investigates the potential furniture part yields from unedged and untrimmed boards compared to both optimal and actual edging and trimming practices. The resulting volume of cuttings from unedged and untrimmed boards was found to be 25 percent higher than from the actual edged and trimmed lumber produced at the mills. Also, the volume of long cuttings (84 in.) was found to be 22 percent higher from the unedged and untrimmed boards. In addition to more efficiently utilizing our timber resources, the overall cost of furniture cuttings from unedged and untrimmed boards was found to be 8 percent less even when considering the additional costs of drying, handling, and processing.

An expert panel identified 32 Ohio sawmill operators who possessed characteristics of innovative individuals. A valid and reliable instrument was administered to the operators to determine their perceived educational needs in 67 job-related competencies encompassing 6 subject matter areas. Results indicated that the typical innovative operator was male, 45 to 54 years old, had a tenure of 20 to 29 years, had some college education, annually produced 5 to 6.9 million board feet of lumber, generated an annual income of $3 million to $4.9 million, and had strong aspirations to seek new information. Job competencies with the highest perceived educational needs were: 1) predicting future lumber prices; 2) understanding environmental laws enforced by regulatory agencies; 3) exporting lumber; 4) motivating employees; and 5) disposing of sawmill wastes in an environmentally safe manner. Forest products marketing and environmental awareness were the two subject matter areas with the highest educational needs. The educational delivery method of one-on-one contact was preferred over group education or self-study. Relationships between operators' characteristics and perceived educational needs ranged from negligible to moderate. Results of this study are discussed in comparison to related research, forest products industry education, and diffusion of innovations. Recommendations are made relative to the type of model used in assessing educational needs of forest products industry personnel. C1 OHIO STATE UNIV,DEPT AGR EDUC,COLUMBUS,OH 43210.

Although current pressboards are satisfactory, dielectric strength, thermal conductivity, dimensional stability, and physical strength could be improved and manufacturing cost reduced. In this study, a limited number of experimental insulating pressboards were made from high-yield hardwood pressure-refined mechanical pulps. Pressboards were evaluated for strength properties, weight change, dimension change, and dielectric properties after oil impregnation. Experimental hardwood insulating pressboard properties were compared to those of softwood insulating pressboards. Results show that strength properties and dimensional stability of experimental hardwood pressboards improved slightly, dielectric constants stayed about the same, dissipation factors increased, and dielectric strength decreased. We conclude that substituting insulating pressboard made from high-yield hardwood mechanical pulp for insulating pressboard made from low-yield softwood kraft pulp in the manufacture of electrical transformers has no advantage.

Earlier studies showed that a primary culm infested initially with a virulent larva allowed subsequent normally avirulent larvae to survive on that cultivar; however, in our study the resistance of secondary tillers was maintained even though the primary culm was infested earlier with virulent Hessian fly larvae. This gene stability for resistance is important for optimizing wheat yield of those cultivars that possess genes resistant to the Hessian fly that are tillering and infested with different biotypes.

The inflection points at which the maximum growth rate occurred were estimated to be 112 days for the body weight and 159 days for the breast- muscle weight. The allometric growth coefficient for pectoralis muscle, relative to the whole-body growth, was 1.23 and significantly greater than those of the gastrocnemius, sartorius, latissimus dorsi and extensor digiti muscles during the first 12 weeks posthatch. Myosin was prepared from pectoralis muscle of turkeys at ages ranging from 15 days of incubation (embryos) to 308 days (adult), and embryonic, neonatal and adult isoforms of myosin heavy chain were detected by monoclonal antibodies in the enzyme-linked immunosorbent assay. In turkey embryos, the embryonic myosin heavy chain isoform appeared by 22 days of incubation. The transition from embryonic isoform expression to neonatal isoform expression was noted shortly after hatch, and the transition from neonatal to adult was initiated at 7 days posthatch and was nearly completed by 28 days posthatch. The circulating thyroxine concentration rose and fell markedly around the time of hatch and fluctuated within the range of 11 to 19 ng/ml. The triiodothyronine concentration fluctuated within the range of 5 to 7 ng/ml after hatch and started to fall at 14 days posthatch to reach the adult level of 3 to 5 ng/ml.

Among 41 parents represented by 10 or more progeny, significant differences were observed in offspring BBRRSV expression. The species Vaccinium lamarckii Camp. (4x) and V. amoenum Ait. (6x) and the cultivars Woodard (6x) and Earliblue (4x) seem to have high frequencies of alleles for BBRRSV resistance. Significant differences were also found among 21 different crosses. The most resistant cross was 'Elizabeth' x 'Earliblue', which had a 23 % BBRRSV incidence. Progeny evaluation revealed that none of the parents involved produced families in which atl plants were resistant; hence, resistance to this virus may be under polygenic control.

Herink on net photosynthesis (A), stomatal conductance (g(s)), and water potential was examined. The effect of water stress was determined also on the same plant species independently and in combination with Armillaria infection. Red oak (Quercus rubra L.) was used as a control to indicate Armillaria virulence on North American trees. Carob (Ceratonia siliqua L.) was resistant to infection. Infection was successful in sour orange (Citrus aurantium L.), but A, g(s), and water potential were unchanged over the 60-day experiment. In olive (Olea europea L.) and oak, A and g(s) were reduced following inoculation with A. mellea. A and g(s) of all species but carob were reduced under water stress. Olive and oak responses to water stress and Armillaria infection were quantitatively similar; however, the two stresses combined did not reduce A and g(s) further. Red oak was strongly susceptible to A. ostoyae infection, but Mediterranean trees were not infected by the same Armillaria isolate. Our results show that Armillaria infection may reduce A and g(s) in susceptible species. C1 USDA,CTR FOREST MYCOL RES,FOREST PROD LAB,MADISON,WI 53705.

Differentiation of foliar cells into gland cells began in the youngest leaf primordia. After differentiation into a 10-celled biseriate structure of two stalk cells, two basal cells, and three pairs of secretory cells, the cuticle of the six secretory cells separated from the cell walls to form a bilobed sac that eventually splits to release its contents. At every developmental stage, the cells of the the gland contained relatively little vacuolar volume. The secretory cells contained extensive endoplasmic reticulum. The plastids of each cell pair were different. At maturity, the apical cells contained proplastids or leucoplasts with only occasional thylakoids. The cell pair below the apical cell pair contained amorphous chloroplasts without starch grains. The basal cell pair contained proplastids or leucoplasts and the stalk cells contained chloroplasts. The stroma to thylakoid ratio in the secretory cell chloroplasts was high. Initially, osmiophilic product was observed most freqently associated with stacked thylakoids, plastid envelopes, and smooth endoplasmic reticulum, although it was associated with all cell membranes. Near the plasma membrane adjacent to cell walls bordering the subcuticular space, the cytoplasm was enriched in smooth endoplasmic reticulum containing osmiophilic material. The apical cell wall of the apical secretory cell pair was reticulated on the inner cytoplasmic side and contained osmiophilic staining on the cuticular side. During early senescence, osmiophilic product was commonly associated with outer mitochondrial membranes. RP DUKE, SO (reprint author), USDA ARS,SO WEED SCI LAB,POB 350,STONEVILLE,MS 38776, USA.

Gutierrezia seedlings grown in 30-cm-deep pots were allowed to develop deep lateral roots out of pots into subsoil. The deep laterals were then excised and photosynthesis and stomatal conductance of the test plants measured before and after root pruning. Photosynthesis (A) and stomatal conductance (g) were at least 49% greater (P < .05) before than after root pruning. Photosynthesis and g were more affected by the removal of four deep roots 30 cm below the surface than by the removal of four shallow roots in the top 30 cm of soil. The soil water extraction patterns in Gutierrezia plants grown in 60-cm soil columns were determined for the upper 30 cm and 30 to 60 cm of soil. Water extraction was significantly greater (P < .05) from the wetter, lower section of the soil column than from the drier, upper column. Higher photosynthesis (138%, P < .05), transpiration (154%, P < .01), stomatal conductance (223%, P < .01), and canopy development (340%, P < .05) were observed in plants with deep roots growing beyond the pots than well-watered, pot-grown plants without deep roots. This was related to higher hydraulic conductance, which in turn appeared enhanced by the greater ratio of deep root length to total root length. Stomatal conductance, photosynthesis, and canopy development in Gutierrezia may be regulated by hydraulic capacity, which is determined largely by deep root development.

The treatments included an unburned control and prescribed winter burns at 3-, 6-, and 9-yr intervals. Basal area treatments were 9, 14, 18, and 23 m2 ha-1 for the merchantable-pine component and were maintained on a 6-yr cutting cycle using single-tree selection. Ten years after the study was initiated, density and quadrat stocking of pine regeneration were negatively correlated with overstorey basal area. The 6-yr burning cycle had higher pine density and better quadrat stocking of pine regeneration compared with any other burn treatment mainly because the 6-yr burning cycle coincided with a bumper pine seedcrop and the 6-yr cutting cycle. Recurring fires tended to result in reduced size of hardwood competition but had less impact on hardwood density. When considering a prescribed burning program in uneven-aged stands of loblolly and shortleaf pines, more attention should be given to density, quadrat stocking, and size of established pine regeneration and to expected seedcrops rather than to the prosecution of rigid burning schedules.

A field experiment was conducted in the San Joaquin Valley of California on mature plum trees. The objectives were to quantify salt tolerance with time and to document the development and impact of salt stress over a 6-year period. After three years, the salt tolerance threshold, measured as the electrical conductivity of saturated soil extracts, for fruit yield was 2.6 dS/m. At salinity levels in excess of the threshold, yield was reduced at the rate of 31 % for each 1 dS/m increase in soil salinity. The continuation of this experiment for an additional three years did not alter the salt tolerance as measured by fruit yield. Attempts to revive trees that had been severely damaged by excess salinity were successful but recovery, depending on the severity of damage, requires several years.

All of the solubility profiles could be described by an initial salting-out followed by salting-in. These events were quantified by a salting-out constant, kl, and a salting-in constant, k2. These constants are correlated with association constants for salt binding so that n and m, the number of moles of calcium bound to different classes of sites which induce the respective changes in solubility, could also be quantitated. The purified alpha(s1)-casein from caprine milk differs from its bovine counterparts in that the parameters k1 and n are somewhat smaller, indicating less salt binding at both 24 and 1-degrees-C. Conversely, for whole caseins, k1 was 6 times larger for caprine, which contains significantly less alpha(s1)-casein, than for bovine whole casein. This suggests stronger Ca2+-casein interactions in caprine whole casein as compared to whole bovine casein. Binding of Ca2+ ions to stronger affinity sites results in greater ''salting-out'' for caprine whole casein. Studies on temperature and ionic strength dependence of the comparative solubilities confirm this hypothesis. C1 USDA ARS,EASTERN REG RES CTR,PHILADELPHIA,PA 19118.

A fractionation scheme was developed for rapid purification of the enzyme for characterization of pectic polysaccharides from smooth bromegrass (Bromus inermis L.). The purified PG had a pH optimum of 4.5 and a hydrolytic temperature stability range of 25-35-degrees-C and yielded only tri-, di-, and monogalacturonic acid after exhaustive degradation of polygalacturonic acid. A pectic polysaccharide fraction was solubilized from bromegrass cell walls with hot sodium phosphate buffer and fractionated by anion-exchange chromatography. Degradation of two uronic acid rich fractions by PG revealed a polydisperse nature of the polysaccharide components. One fraction contained a complex makeup of neutral sugars along with rhamnogalacturonans that exhibited limited degradation. The other fraction contained fewer neutral sugar components, and the rhamnogalacturonans were extensively degraded. Compositional characteristics of these polymers were similar to those of rhamnogalacturonans isolated from other plants. C1 USDA ARS,US DAIRY FORAGE RES CTR,MADISON,WI 53706.

For development of the method, a commercial arginase was used as the model system. Steps for detection include subjecting the arginase to gel electrophoresis and electrotransferring to a PVDF membrane where the arginase was detected with Arg-LC-biotin-avidin-HRP and visualized as a colored band after incubation with a HRP substrate. Requirements for successful detection include use of a spacer arm (i.e., -LC-) inserted in an Arg-HRP conjugate and a buffer (sodium borate) which does not interact with manganese chloride (MnCl2) to form precipitates during incubation. MnCl2 is required for activating and facilitating the arginase to bind to Arg-LC-biotin-avidin-HRP. The conjugate was prepared through a sequential reaction between arginine, N-(hydroxysuccinimido)-6-aminohexanoate-biotin (NHS-LC-biotin), and avidin-HRP. The sensitivity of the assay was 2 mug of arginase on the membrane. The Arg-LC-biotin-avidin-HRP also detected ovalbumin, arginine decarboxylase, and kinase except for bovine serum albumin and alkaline phosphatase. Application of the method to a crude peanut extract revealed several proteins having an affinity for arginine. The role of these arginine-binding proteins in reduction of the free arginine level in peanuts is discussed.

Metabolism occurred predominantly by benzylic hydroxylation of one of the arylethyl side chains. Metabolites were separated by reversed-phase high-performance liquid chromatography and identified by H-1 nuclear magnetic resonance, UV, and mass spectral techniques. Two major metabolites were isomers of 2-chloro-N-(methoxymethyl)-N-[2-ethyl-6-(l-hydroxyethyl)-phenyl]acetamide and another was 2-chloro-N-(2,6-diethylphenyl)acetamide; the minor metabolite was 2-chloro-N-(methoxymethyl)-N-(2-vinyl-6-ethylphenyl)acetamide. The fungal transformations appear to be similar to those of mammalian microsomal oxidation since C. elegans oxidized alachlor at the benzylic positions and N-dealkylation occurred.

The effects of volatile compounds from this pathway on the proliferation of Escherichia coli TB1, Pseudomonas syringae pv. tabaci, and Pseudomonas syringae pv. angulata were evaluated. The vapor-phase concentrations of compounds in the bioassay system were estimated by gas chromatography. At the highest concentrations tested, the C6 aldehyde (E)-2-hexenal completely inhibited proliferation of both P. syringae pathovars (570 mug/L of air) and E. coli (930 mug/L of air). Similarly, the C6 alcohol (E)-2-hexen-1-ol prevented proliferation of P. syringae pathovars (1100 mug/L of air) and E. coli (2300 mug/L of air). Among the bacteria tested, one isolate of P. syringae pv. angulata was the most sensitive to a lipoxygenase pathway volatile, exhibiting decreased proliferation after exposure to (E)-2-hexenal (40 mug/L of air). The unsaturated volatiles, (E)-2-hexenal and (E)-2-hexen-1-ol, exhibited a greater inhibitory effect than the saturated volatiles, hexanal and 1-hexanol. The responses to the volatile compounds observed for E. coli TB1 and P. syringae pv. tabaci were similar and differed somewhat from that of P. syringae pv. angulata.

Wavelength integrated absorbance is computed which asymptotically approaches a maximum as more pixels are used to cover the absorption profile. The read noise of the LPDA was 3800 electrons. Absorbance noise computed from the propagation of errors and LPDA read noise accurately predicts the experimental results. Absorbance noise decreases as the entrance slit is increased and increases as the number of pixels in the calculation is increased. The best detection limits were found with an entrance slit-width of 500 mum and 16-32 pixels. The detection limits for Cd, Cu and Ni were comparable to line source atomic absorption spectrometry. Gated detection was necessary to eliminate source flicker when large numbers of pixels were used and in the presence of background absorbance.

The methods were fecal collection bags (B) and marker estimates of fecal output (U). A control treatment (C) was included in each experiment in which wethers were not bagged or dosed with the marker. Experiment 1 was conducted with wethers grazing dormant sagebrush-bunchgrass range. Experiment 2 was conducted with wethers housed in metabolism crates. In Exp. 1, the following differences were detected: 1) basal and mean integrated (following ACTH challenge) plasma cortisol levels were higher ( P < .0 5) for U wethers than for C wethers, 2) no differences (P > .0 5) between B and C wethers were detected for basal or mean integrated plasma cortisol, 3) both B and U wethers gained (P < .05) weight, whereas C wethers lost weight, and 4) no differences (P > .05) between B and U wethers were detected for cortisol measurements, weight change, or fecal output. No differences (P > .05) were noted for any of the variables tested in Exp. 2. When treatments were combined within experiment to test Exp. 1 vs 2, time to peak cortisol levels was longer (P < .05) and mean integrated cortisol levels and weight change were lower (P < .0 5) for wethers in confinement than for wethers on range. No difference (P > .05) was detected for basal cortisol levels. We conclude that fitting wethers with fecal collection bags or dosing them with an inert marker for grazing and confinement research does not adversely affect the estimate of fecal output or cause undue stress.

Implanting ram and wether lambs once (1990) or twice (1991) with 12 mg of zeranol did not change live weight or ADG but gain/feed decreased (P <.05) in ram lambs slaughtered at approximately 50 kg. Testes weight was reduced approximately 50% by implanting. Two implants reduced (P < .05) the force needed to pull the pelt from the hind legs of ram lambs, but implanting tended to increase the force required to pull the pelt from wether lambs. Data for pelt weight, force required to pull the pelt, percentage of the carcass in the shoulder or splenius muscle, and Warner-Bratzler shear values showed that zeranol implants resulted in ram lambs becoming more like wethers and wether lambs becoming more like rams. Implanting with zeranol did not affect closure of the metacarpal growth plate in ram or in wether lambs. Difficulty of pelt removal can be reduced by implanting ram lambs with 12 mg of zeranol at approximately 114 d of age and reimplanting zeranol 28 d later. C1 USDA,DUBOIS,ID 83423.

Lambs were fed a finishing diet with or without 4 ppm of L644,969 and slaughtered after 0, 2, 4, and 6 wk of treatment. The ADG was higher (P < .05) in the treated than in the control lambs after 2 wk and returned to control levels thereafter. Semitendinosus weight and calpastatin activity were higher and mu-calpain activity was lower in the treated than in the control lambs after 2, 4, and 6 wk, Cathepsin B activity was higher (P < .01) and cystatin-like activity was lower (P < .0 5) after 2 wk in treated than in control lambs but returned to control levels thereafter. Longissimus protein:DNA was higher after 4 (P < .05) and 6 (P < .01) wk in the treated lambs than in the controls. The concentration of RNA and RNA:DNA ratio were higher (P < . 0 1) in the longissimus and semitendinosus muscles in the treated lambs after 2 wk and remained higher throughout the study. Semitendinosus protein and RNA content were higher after 2, 4, and 6 wk and DNA content was higher after 2 and 6 wk in the treated than in the control lambs. Longissimus shear-force values were higher (P < .001) in the treated than in the control lambs at all slaughter end points. These data indicate a rapid alteration of muscle growth, activity of the calpain-calpastatin system, and meat tenderness during BAA treatment. It also seems that the BAA-stimulated muscle growth is closely related to the activity of the calpain-calpastatin system. C1 USDA ARS,ROMAN L HRUSKA US MEAT ANIM RES CTR,CLAY CTR,NE 68933.

Each ewe was inseminated immediately upon detection of estrus with 7.5 x 10(8) progressively motile sperm placed into the external os cervix. Ewes were hysterectomized at either 2 or 22 h after insemination. Sperm were recovered from the uterus, isthmi, and ampullae by flushing with sterile .9% saline. The distribution of sperm recovered from the uterus, isthmus, and ampulla did not differ (P > .10) among 1E, 3E, and MAT ewes at either 2 or 22 h. However, there was a tendency (P = .08) for more sperm to be recovered from the anterior reproductive tract in 3E and MAT ewes than from that in 1E ewes. There was a time of hysterectomy x anatomical segment interaction (P < .05) for percentage of sperm recovered of the total number of sperm in the inseminate because more sperm were recovered from the isthmus and ampulla at 22 h than at 2 h after insemination. Percentages of 1E, 3E, or MAT ewes from which sperm were recovered from the anterior reproductive tract did not differ (P > .10). However, sperm were recovered from the oviducts in a greater (P < .05) percentage of ewes at 22 h after insemination than at 2 h. We conclude that sperm transport through and distribution of sperm within the anterior reproductive tract may not be major limiting factors in regulating fertility during the puberal transition in ewe lambs.

Dams were slaughtered at an average of 231 d of gestation. Daily blood samples were obtained from the dam on d 228 to 231 to determine serum estradiol, progesterone, and testosterone concentrations. Pelvic height was greatest (P < .05) in B, C, and L and pelvic width was greatest (P < .0 5) in S, C, and J dams, but pelvic areas did not differ (P > . 1 0). Dams with greater hip height had larger pelvic areas (r = .45; P < .01). Intact fetuses from C and S dams were heaviest (P < .05), those from S dams had the greatest (P < .05) head width, and heart girth was greatest (P < .05) in fetuses from L dams. Fetuses from H sires were greater in weight (P < .01), body length (P < .01), and cannon circumference (P < .01). Dam differences were found in fetal heart weight (P < .01), trimmed placental membrane weight (P < .01), and average placentome weight (P < .05). Weights of eviscerated fetuses were greatest from C dams (P < .05). Placentome number was lowest (P < .05) in J dams, but J dams had the highest (P < .05) average placentome weight. Interactions between fetal genotype and breed of maternal environment were found for weight of eviscerated fetus (P < .05), body length, and heart weight (P < .01) and resulted from both magnitude and direction of change in the sire effect. The H sire increase in fetal weight was greatest in J dams, whereas B dams allowed expression of the fetal growth potential but at a lower level. Fetal trait interactions were also found for breed x sex and sex x sire (P < .05 to P < .01) and were due to the magnitude of differences expressed between the M and H sires. Serum testosterone concentrations were highest (P < .05) in B and L dams, dams gestating fetuses sired by the H sire (P = .08), and those with male fetuses (P < .01). We interpret these results to indicate that some maternal environments can suppress fetal growth, whereas others seem to complement the growth and allow maximum expression of the fetal genetic growth potential. We speculate that dams gestating male fetuses are subjected to prolonged testosterone influence, which may affect subsequent dystocia, calf survival, and the incidence of retained fetal membranes.

During each period of the crossover design all lambs were limit-fed a 36% concentrate diet for 16 d then two lambs were deprived of feed and water for 3 d. All lambs were then limit-fed the 36% concentrate diet. Glucose loading tests were performed before feeding on d 1, 5, and 9 of the realimentation period. Ten milliliters of a 2.5 M glucose solution were infused into the right jugular vein and blood samples were obtained from the left jugular vein at intervals for 4 h after infusion. Plasma or serum samples were analyzed for insulin, growth hormone (GH), somatostatin, prolactin, glucose, free fatty acids (FFA), and urea N. At the end of the period in which feed was withheld, fed lambs had greater (P < .09) serum insulin and lower plasma FFA (P < .01) and somatostatin (P < .05). On d 1 of realimentation, previously unfed lambs had greater postinfusion GH (P < .01), FFA (P < .01), and glucose (P < .04) concentrations. Previously unfed lambs also had a slower (P < .01) glucose fractional removal rate and longer (P < .02) glucose half-life than fed lambs on d 1 of realimentation, but they had a shorter (P < .13) glucose half-life than fed lambs on d 5 of realimentation. Results of this study are interpreted to indicate that withholding feed from lambs for 3 d has marked effects on hormonal secretion and metabolite utilization that may not be indicated by a single blood sampling.

Wether lambs were progeny of five ram breeds (Dorset, Finnsheep, Montadale, Romanov, and Texel) and two ewe breeds (Rambouillet and a composite breed [1/2 Columbia, 1/4 Suffolk, 1/4 Hampshire]). Diets were adjusted to decrease crude protein twice during the experimental period, with analyzed copper levels for the three diets of 5.2, 4.4, and 3.6 ppm. All means were adjusted to a constant carcass weight of 27.265 kg using a covariate analysis. Least squares means of the liver copper concentration for sire breeds ranged from 307 to 458 mug/g on a DM basis. Romanov- (307 mug/g) and Finnsheep-sired (327 mug/g) lambs had the lowest liver copper concentration, whereas Montadale-(359 mug/g) and Dorset-sired (360 mug/g) lambs were intermediate and Texel-sired (458 mug/g) lambs were significantly higher compared with other lamb breeds. Least squares means for total liver copper for the five ram breeds ranged from 69 to 101 mg. Finnsheep- (69 mg), Romanov- (72 mg), and Montadale-sired (80 mg) lambs were lowest, Dorset-sired (85 mg) lambs were intermediate, and Texel-sired (101 mg) lambs were higher (P < .02) compared with other lamb breeds for total liver copper. Least squares means for serum copper ranged from .86 to 1.05 ppm. Levels of serum copper were similar for Montadale- (.86 ppm), Finnsheep- (.90 ppm), Texel- (.93 ppm), and Dorset-sired (.94 ppm) lambs and higher (P < .02) for Romanov-sired (1.05 ppm) lambs. Progeny of composite ewes had lower (P < .01) serum copper (.88 ppm) than progeny of Rambouillet ewes (.99 ppm). At dietary copper levels fed in this experiment, Texel-sired progeny had higher liver copper levels than other breeds; however, both liver and serum copper levels for all breed types were in the normal nontoxic range.

Sulfabromomethazine (SBZ) is added to the tissue as an internal standard. SMZ and SBZ are extracted from the tissue into water as the supernatant of a centrifuged, aqueous homogenate and are cleaned up and concentrated by a series of solid-phase extractions. The sulfonamide-containing eluate is then separated on a silica gel thin-layer chromatographic plate. SBZ and SMZ are derivatized with fluorescamine, and their fluorescence is quantitated with a scanning densitometer. The limit of detection was estimated at 0.25 ppb (signal-to-noise ratio, 3:1). The average accuracy over the analysis range (0.54-21.8 ppb [mug/kg]) was 95.6% (standard deviation = 29.4%, n = 54).

Part of this controversy is due to the complex interactions between pathogens and host defense mechanisms as well as to the mutable nature of exercise. Psychological influences and normal temporal variations in immune mechanisms have also complicated the issue. An understanding of how each of these factors affects host defense should help in the design of new experimental approaches to the problem as well as in the interpretation of previously published results.

The major vegetation zones of the world are predicted by a two-dimensional ordination of a Dryness Index and Potential Evaporation, which is derived from radiation balance. Mean temperature of the warmest month is also used to separate the Ice/Polar Desert, Tundra, and Taiga zones. Predictions of vegetation distributions are made using a global climate database interpolated to a 0.50 by 0.50 terrestrial grid. The overall impression from examining the resulting global vegetation map is that the modified Budyko model predicts the location and distribution of the world's vegetation fairly well. Comparison between model predictions and Olson's actual vegetation map were based on Kappa statistics and indicate good agreement for Ice/Polar Desert, Tundra, Taiga, and Desert (even though we predict too much Desert). Agreement with Olson's map was fair for predicting the specific location of Tropical Rain Forest and Tropical Savannas, and was good for predicting their general location at a larger scale. Agreement between Olson's map and model predictions were poor for Steppe, Temperate Forest, Tropical Seasonal Forest, and Xerophytic Shrubs, although the predictions for Temperate Forest and Tropical Seasonal Forest improved to fair at a larger scale for judging agreement. Agreement with the baseline map of Olson was poor for Steppe and Xerophytic Shrubs at all scales of comparison. Based on Kappa statistics, overall agreement between model predictions and Olson's map is between fair and good, depending on the scale of comparison. The model performed well in comparison to other global vegetation models. Apparently the calculation of radiation balance and the resulting Dryness Index and Potential Evaporation provides important information for predicting the distribution of the major vegetation zones of the world.

This plant response could be induced by merely placing the cut stem of seedlings in a solution of BAW regurgitate for 12 hr, a response that could not be induced by placing seedlings in water only. Regurgitate of BAW fed various diets, including a minimal diet of filter paper, were all active. However, seedlings placed in com leaf juice, BAW hemolymph, or BAW feces extract released significantly smaller amounts of terpenes than did seedlings placed in BAW regurgitate. These results indicate that the active components are present in relatively large concentrations in regurgitate and that they are not related to the food source. Furthermore, regurgitate from several other species of caterpillars (Spodoptera frugiperda. Helicoverpa zea, Trichoplusia ni, and Anticarsia gemmatalis) as well as from the grasshopper Schistocerca americana induced the release of significant amounts of terpenes in com seedlings. The release of these volatiles, therefore, appears to be a general response to attack by phytophagous insects. The terpene-releasing com seedlings were highly attractive to the generalist parasitoid Cotesia marginiventris and to the specialized parasitoid Microplitis croceipes. This study confirms a systemic herbivore-elicited release of terpenes in com. It is proposed that such chemicals serve multifunctional purposes that directly and indirectly protect plants against herbivorous arthropods and pathogens.

Gas chromatography-mass spectrometric analysis of extract of the female sex pheromone glands showed the presence of Z9-14 : Ac (8.5 ng/female), (Z)-9-tetradecen-1-ol (Z9-14 : OH), and (Z)-11-hexadecen-1-ol acetate (Z11-16 : Ac) in a ratio of 100:4:21, respectively. In tests in sugar beet fields, Z9-14 : Ac alone produced some trap catch. Addition of Z9-14: OH did not increase catch while addition of Z11-16 : Ac eliminated catch, but addition of both Z9-14 : OH and Z11-16 : Ac increased catch sevenfold.

The damage to corn is caused primarily by larval feeding on leaf, ear, and stem tissues. In this study, 2-hydroxy-4,7-dimethoxy-1,4-benzoxazin-3-one (N-O-Me-DIMBOA) was identified by MS and NMR as present in corn whorl surface waxes. This compound has evidently not been isolated previously, but its glucoside has been reported in corn, wheat, and Coix lachryma. It is present in the waxes in a higher concentration than DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) and 6-MBOA (6-methoxybenzoxazolinone). It was toxic to the SWCB in a stress diet, but it was less toxic to this insect than 6-MBOA when incorporated in the standard rearing diet. Nevertheless. it may have some role in the resistance of com to the SWCB because the total surface wax content is higher in resistant lines than in susceptible lines.

Centrifugation of bacteria culture yielded a slightly attractive pellet containing most of the bacteria cells and a highly attractive supernatant. Supernatant filtered to remove the remaining bacteria was as attractive as the unfiltered supernatant. Filtrate at pH 7 and above was much more attractive than filtrate at pH 5 and below. Most of the attractiveness was retained on strong cation exchange media under acidic conditions and eluted with base. Attractive principles could not be trapped on adsorbents such as Porapak Q or extracted with organic solvents from aqueous preparations, but they were easily collected by headspace sweeping with steam. The attractive components were efficiently concentrated by rotary evaporation of steam distillate at pH 5, but at higher pH much of the attractiveness distilled. A reverse-phase HPLC method using a negative counter-ion was developed to separate and collect attractive components of concentrated steam distillate. Attractive fractions collected using this method were concentrated and injected onto silica HPLC. Activity eluted from silica in two distinct bands. Results suggest that the most attractive components of the bacterial odor are highly polar, low-molecular-weight amines.

BVDV and BDV are found worldwide but seldom cause disease in swine. In contrast, HCV has been successfully eradicated from swine in several nations but poses a potentially devastating threat to them because of its great virulence. Rapid differential diagnosis of HCV from BVDV and BDV infections in swine is vital for detection of the possible reintroduction of HCV into national herds from which it has been eradicated. Nested polymerase chain reactions (PCRs) for each of two pestiviral genomic segments are described. Amplification of the relatively conserved 5' genomic terminus identified 59 of 61 HCV, BVDV, and BDV isolates generically as pestiviruses. Nested amplification of the second region was designed to differentiate HCV from BVDV and BDV by exploiting relatively conserved differences in the nucleotide sequences that encode the major envelope glycoprotein. This second PCR correctly identified 36 of 36 diverse HCV isolates while failing to recognize any of 25 BVDV and BDV isolates. Multiple restriction fragment length analyses confirmed the identities of both external and nested PCR products. The two sets of PCRs may help confirm the generic identity of most pestiviruses and may permit presumptive differential diagnosis of HCV from BVDV and BDV.

Five previously unidentified EcoRI digestion patterns and one previously unidentified HhaI digestion pattern were seen with the various isolates. The copy number and genomic distribution of an L. borgpetersenii insertion sequence (IS1533) was determined. Hardjo-bovis isolate 033 (the type strain for hardjo-bovis) contained 40 well dispersed copies of IS1533. IS1533 probes were used to compare hardjo-bovis isolates by DNA blot hybridization analysis. Use of these probes showed the presence of additional genetic heterogeneity among hardjo-bovis isolates, which restriction endonuclease analysis did not show. Pulsed-field gel electrophoretic analysis of DNAs from several isolates suggested that some polymorphisms arose by genomic rearrangements. All hardjo-bovis isolates were categorized into 14 distinct groups on the basis of common hybridization and endonuclease digestion patterns. Most of these groups were isolated from distinct geographical regions, suggesting that several different clonal populations of hardjo-bovis exist.

Bucket and quarter milk SCC were collected at weekly intervals. Individual milk weights were obtained at milking, and samples were obtained for determination of SCC. The milk weights at the corresponding a.m. milking on the following day were also obtained. A dilution effect was assumed to cause the regression of milk yield on milk SCC to diminish when adjustment was made for milk yield on the day following sampling for SCC. Regressions of milk yield on various functions of SCC decreased by about one-half when adjustment was made for the next day's milk yield, but the regressions remained significant. The observed negative relationship between milk yield and SCC may partly reflect both the true biological effects of udder inflammation and a dilution effect. The carry-over effect of SCC on milk yields measured 1 wk after cell counting was investigated, but no effect was significant.

These effects usually have been ascribed to increased ruminal buffering capacity, but this mode of action has several problems. For the buffering capacity to increase, the concentrations of ruminal bicarbonate, dissolved CO2, and Na have to increase. Ruminal fluid already is saturated with CO2, and the cation concentration of ruminal fluid is regulated closely to prevent hemoconcentration or hemodilution. Based on these latter observations, a significant increase in ruminal buffering capacity is unlikely. The action of bicarbonates is explained more easily by increased water intake, increased ruminal fluid dilution rate, increased flow of undegraded starch from the rumen, and decreased ruminal propionate production.

(Coleoptera: Chrysomelidae), in North America. Studies using light and electron microscopy reveal that this species completes its life cycle in direct contact with the cytoplasm of cells within the fat body, midgut, hindgut, muscles, central nerve cord, Malpighian tubules, tracheal end cells, and ovaries. The microsporidium is monomorphic, all life stages are diplokaryotic, and spores develop from disporous sporonts. The mature spores are broadly oval and measure 4.2 +/- 0.10 x 3.4 +/- 0.04 mum. Spores contain a tubular polar filament that is arranged peripherally in a single layer of 13-15 coils. Both horizontal transmission and vertical transmission have been demonstrated for this microsporidium in C. scripta in the laboratory. The Colorado potato beetle, Leptinotarsa decemlineata (Say), was susceptible to infection with this pathogen in cross-infectivity studies.

When Cl- is included in the bathing solution, changes in the cellular concentrations of ammonium, K+, Cl- and Na+ have been shown to meet the requirements for electroneutrality and to account for the changes in vacuolar osmotic pressure associated with ammonium uptake. If accumulation occurs in the absence of external Cl-, however, changes in the inorganic ions do not meet these criteria. Malate is found in the vacuoles of cells accumulating amine in the absence of external Cl- and its presence (at 0.5 to 8.5 mol m-3) allows us to account for electroneutrality and for changes in the osmotic potential.

Cultures were sampled at selected times, and plate counts were used to calculate growth curves under each condition. None of the three strains grew at 5-degrees-C, but growth did occur slowly at 8-degrees-C, and was most rapid at a temperature of 37-degrees-C. Growth occurred in media without additives in all pH's examined between 8 and 42-degrees-C. Decreasing the pH and increasing levels of sodium chloride and sodium nitrite increased the lag phase and generation times of the organism.

The cecal contents and feces of two pigs were positive (4%) with the pathogenic serotype O:5,27, biotype 3, whereas all other pigs were negative for pathogenic serotypes of Y. enterocolitica. The pathogenic serotypes were isolated from the cecal contents and feces using the stomacher sampling method. The cold enrichment in phosphate buffered saline and plating in Cefsulodin-irgasan-novobiocin medium. No pathogenic serotypes were recovered using the swab sampling technique, enrichment in Irgasan-ticarcillin-chlorate, and plating in modified Salmonella-Shigella deoxycholate-calcium chloride medium. The isolation of only 4% positive pathogenic Y. enterocolitica in our sampling of pigs in one production unit provides some encouragement that detection and control procedures might be effectively implemented to reduce or eliminate serotype 0:5,27 from that herd.

Pasteurization reduced firmness in the absence, but not in the presence, of added CaCl2. CaCl2 significantly (P less-than-or-equal-to 0.01) reduced softening during storage of 'Red Cherry' peppers at higher temperatures (36.7, 46.7-degrees-C), and resulted in a slight increase in firmness at 26.7-degrees-C. CaCl2 did not significantly (P greater-than-or-equal-to 0.05) improve firmness retention in 'Jalapeno' peppers, but resulted in greater uniformity of firmness.

In contrast the untreated control pear quarters darkened and became very soft. Less than 50% weight loss by osmotic concentration was not as effective in preventing loss of texture and color qualities. Hot-air drying, in combination with osmotic drying or alone, was more rapid, but did not keep the product from darkening or from becoming soft on freezing and thawing. After hot-air drying the pear core area turned pink. This did not occur after osmotic dehydration. The water activity decreased from 0.97 to 0.93 in this range of concentration, and the rate of decrease closely parelleled the reduction in moisture.

Plant weight increased over time, and those plants grown at a 16 h photoperiod showed the greatest increase. Plants began to produce tubers after 70 to 77 days at all photoperiods. Plants grown at the 16 h photoperiod and those initially grown at 16 h and switched to the 10 h photoperiod allocated less biomass to new tubers (ca. 5%) than those grown at the 10 h photoperiod (ca. 30%). Plants grown at the 10 h photoperiod had decreased weights of stems and leaves. Plants grown at the long photoperiod produced tubers after attaining dry weights between 0.8 and 1.0 g. Plants grown at the short photoperiods produced tubers regardless of plant weight, but the frequency of tuber production increased for larger plants. Changes in the pigment and protein content of leaves were not associated with the onset of tuber production. C1 NETHERLANDS INST ECOL,3631 AC NIEUWERSLUIS,NETHERLANDS.

Merr] that alters flower development and produces apetalous male-sterile flowers. The apetalous male-sterile soybean mutation exhibited floral structure abnormalities similar to several homeotic gene mutations in Antirrhinum and Arabidopsis. Stereoscopy, light microscopy, and scanning electron microscopy observations were made on flower buds at different developmental stages. The characteristic features were the lack of standard petal, lateral wings, and keel petals and the appearance of an elongated sepaloid calyx. Gynoecia were characterized by enlarged unfused ovaries and exposed ovules. The number of stamens was reduced, and various levels of stamen malformation were observed. Male sterility was documented, and it was attributed to tapetum malfunction. Genetic studies indicated that a single recessive nuclear gene is responsible for this apetalous male-sterile character in soybean. No linkages were detected with Ln (leaflet shape), Pb (pubescence tip), Enp (endopeptidase), Ap (acid phosphatase), Pgi2 (phosphoglucose isomerase), Idh2 (isocitrate dehydrogenase), or Aco2 (aconitase).

Aberrations observed in the six cultivars included primarily tetraploid (2n = 28) and aneuploid cells. Plant regeneration decreased and cytogenetic aberrations increased with culture duration, but relative cytogenetic stability was not related to the ability to regenerate plants.

A female sterile mutant in pearl millet was identified previously as having apomictic characteristics. The objectives of this study were to observe the cytology of female sterile ovules after pollination to determine possible reasons for sterility and a possible link to the aposporous apomictic developmental process. Cytological examination of 273 ovules revealed that they are small and deformed; 50% failed to form embryo sacs, and 35% formed multiple embryo sacs, which indicates the potential for apospory. Only 12% contained antipodal cells typical of sexual embryo sacs. In general, the embryo sacs occupied most of the ovule area limiting the amount of nucellar tissue available for endosperm and embryo development. Only six of the 273 ovaries observed had endosperm and/or proembryo development. This recessive mutation represents a possible step in the genetic regulation of apomictic development.

Genome size of hybrid offspring was exactly intermediate to the genome sizes of parental stocks, indicating that nuclear DNA segregates as a function of haploid DNA content and is stable within intergeneric hybrids. Thus, measuring genome size could provide a useful method for identifying hybrids within natural populations of fish or other organisms. Within-group variation in genome size was less than 2.5% for all groups studied, including outbred parental stocks. These values may represent the minimal level of genome size variation detectable within populations by analysis of interphase nuclei. The variation in genome size of ictalurid catfishes is small compared to variation observed in other vertebrates, and may be due to evolutionary conservatism within the catfish genome or to the appearance in other taxa of mechanisms that generate variation in DNA mass.

Rows of dead termites locked in combat were found within the corrugations, with additional dead termites usually in the soil beneath the roll. Dead soldiers constituted 64 to 100 % of termites recovered from sites of intercolony conflict. Ongoing intercolony aggression is likely involved in the maintenance of discrete H. aureus territories.

Darcy's law and the continuity equation, expressed in cylindrical coordinates, were solved for flow in a vertical cross section of a two-dimensional aquifer. The lower horizontal boundary and the vertical boundaries at r = 0 and r = a are no-flow boundaries. The upper horizontal boundary is a prescribed head consisting of a linear increase with radius onto which is superimposed a sine wave. In plan view, the streamlines are radially convergent. The converging system shows a concentration of streamlines near the divide and a spreading of streamlines near the apex due to the prescribed potential on the upper boundary that limits the rate of water movement toward the apex. The effect of relief on local flow systems is limited, especially in the region near the valley bottom. C1 UNIV MISSOURI,DEPT AGR ENGN,COLUMBIA,MO 65211.

The results are compared with measured runoff and sediment yield. The computed and measured runoffs show reasonable to poor agreement. The average ratios of computed to measured sediment yields for the various storms and watersheds show a large scatter. ANSWERS provides the most consistent results for estimates of runoff and sediment yield. All three models tend to underestimate sediment yield for large storms. For high intensity and low intensity storms on two small watersheds, the detachment models in ANSWERS and CREAMS have biases (ratio of calculated to measured sediment yields) that range between 0.9-1.0 and 0.4-1.6, respectively.

To characterize the lipid composition of monkey sperm and to establish a baseline from which dietary or pharmaceutical influences may then be evaluated, we collected semen samples from five rhesus monkeys by electroejaculation and analyzed the sperm for sterols, fatty acid composition, and the molecular species of the ethanolamine glycerophospholipids. Two sterols were identified: cholesterol, 41%, and desmosterol, 59% of total sterols. Desmosterol was found only in the free form. Cholesterol existed in three different forms: free, 60%; esterified, 20%; and sulfated, 20%. Docosahexaenoic acid (22:6, DHA) was almost the only n-3 fatty acid in sperm phospholipids, 24% of the total fatty acids. DHA was present mainly in phosphatidylcholine and phosphatidylethanolamine. Oleic and palmitic acids were the predominant monounsaturated and saturated fatty acids. The ethanolamine glycerophospholipids were separated into three subclasses: diacyl 49%, alkenylacyl 43%, and alkylacyl 8%. Thirteen molecular species were identified and quantified. The sn-1 position of these molecular species contained exclusively 16:0, 18:0, or 18:1. The sn-2 position contained n-3, n-6, and n-9, as well as saturated fatty acids. The molecular species having n-3 fatty acids in the sn-2 position contributed 43, 73, and 100% of the total in the diacyl, alkenylacyl, and alkylacyl subclasses, respectively. The presence of the unusual sterol, desmosterol, a cholesterol precursor not found in measurable quantities in any other tissue suggests an important functional and structural role for desmosterol in spermatozoa. The other unique lipids, cholesterol sulfate and the n-3 docosahexaenoic acid, may also have a significant role in the function of spermatozoa.

Northern fowl mite proteins were obtained by affinity chromatography and used for immunization. Western blot analysis identified proteins that were reactive with sera from birds immunized with the antigen; this indicated that serum antibodies against the northern fowl mite had been produced. Chickens that had been immunized or infested, or both, with the northem fowl mite produced sera that were reactive with a 100 kilodalton (kD) protein. The response was greater if the chicken had been immunized with the antigen and infested with the northem fowl mite. Experimentally immunized and infested chickens experienced limited decreases in the levels of northem fowl mite infestation. Survival of bloodfed mites after ingestion of the immune chicken blood was assessed in an in vitro feeding study using blood-filled parafilm sacs; minor differences in northem fowl mite feeding tendencies were noted. The chickens developed antibodies to the northem fowl mite proteins, but this immunity did not decrease the infestation level or in vitro feeding.

Eggs laid by pyriproxyfen-treated fleas within 70 h after exposure to this juvenoid were often devoid of yolk and frequently collapsed after oviposition. Minimal amounts of yolk were deposited in eggs laid after 70 h, and no blastoderm was formed. These results are significant because both modes of action were different than those observed earlier by investigators studying ovicidal effects in adult insects treated with juvenile hormone. In contrast to the pyriproxyfen results, eggs laid by methoprene-treated fleas showed no gross morphological effects, and these eggs remained turgid during embryogenesis. However, the eggs either did not hatch or the larvae died within hours after hatching. Histological examination of the eggs revealed that most of the eggs contained segmented embryos which had apparently died during blastokinesis. Although eggs of some insects exposed to juvenile hormone during oogenesis fail to undergo germ band formation, there was no evidence of this effect in methoprene-treated cat fleas.

The loci examined coded for alpha-glycerophosphate dehydrogenase, octanol dehydrogenase, and phosphoglucomutase. Flies were sampled by traps widely distributed in Colima Province, southwestern Mexico. Gene frequencies at Odh differed significantly among the 11 populations. Alleles segregating at Pgm and alpha-Gpdh were homogeneous among populations. There were significant departures from random mating within populations, but no genetic differentiation among populations was detected. The data suggest unrestricted gene flow among populations. Departures from random mating within populations were explained by the pooling of samples from separate breeding units. C1 US EMBASSY,USDA ARS,SCREWWORM RES LAB,POB 3149,LAREDO,TX 78041.

Percentage C. caryae parasitism by S. carpocapsae and H. bacteriophora strain HP88 and Georgia was consistently poor when applied either prior to or following C. caryae entry into the soil, suggesting that these nematode species and (or) their enterobacteria are poor biological control agents of weevil larvae. Soil taken 21 days following application of S. carpocapsae or H. bacteriophora strain HP88 induced a low rate of infection of Galleria mellonella larvae, whereas soil that had been similarily treated with H. bacteriophora strain Georgia induced a moderate rate of infection.

Root explants were taken from 2-day-old seedlings cultured for 30 days at 28 C on Gamborg's B-5 medium with or without nematode inoculum. The remaining portion of the root and stem from the excised root explants was transferred to soil in pots and grown to maturity in the greenhouse. In vitro root explants were evaluated for growth and occurrence of juveniles, adults, and egg masses. The regenerated plants were used to produce more seed. The proposed technique is simple, reliable, and adapted to routine screening of large numbers of F1 and F2 samples, and it utilizes less space than tests performed on intact plants in the greenhouse or growth chamber. Evidence is presented also on the breakdown of resistance to M. incognita under high temperature stress using this in vitro root explant technique.

The present study was undertaken to determine effects of oral arginine supplementation on in vitro measures of immune function using a stressed rat model. The stressor used was intraperitoneal injection of bacterial lipopolysaccharide (1 mg/kg body wt). Four-month-old male Sprague-Dawley rats were placed in either a control or an arginine-supplemented (7.5 g/L arginine-HCI in drinking water) group for 7 d, after which control and supplemented rats received injections of endotoxin or phosphate-buffered saline. Rats were killed 3 d following injections. Endotoxin treatment resulted in lower food intake, less thymic cellularity and greater splenic weight. Endotoxin injections also enhanced proliferative response of rat splenocytes to pokeweed mitogen (1 mg/L) and lipopolysaccharide (25 and 100 mg/L) and enhanced response of thymocytes to concanavalin A (10 mg/L), phytohemagglutinin (25 and 100 mg/L) and pokeweed mitogen (1 mg/L). Supplemental arginine did not reduce thymic weight loss or influence mononuclear cell proliferation or interleukin-2 production in the presence or absence of endotoxin stress. These data indicate no benefit of arginine supplementation during endotoxin stress in rats. RP TORRE, PM (reprint author), TUFTS UNIV,USDA ARS,HUMAN NUTR RES CTR AGING,BOSTON,MA 02111, USA.

We therefore examined the concentration of vitamin K1 in two widely used intravenous lipid emulsions by using a previously validated high performance liquid chromatography technique. The vitamin K1 concentrations of 10% emulsions of Intralipid and Liposyn II were 30.8 and 13.2 mug/dL, respectively. The concentration of vitamin K1 in the 20% emulsions of these products was essentially double that in the 10% emulsions. The coefficients of variation between the vitamin K1 content in three different lots of each product were consistently less than 7.0%. The observed concentrations of the vitamin in these lipid emulsions paralleled the predicted content on the basis of the type of vegetable oil(s) used to make the product. The type of vegetable oil used for production therefore seems to be a major determinant of the final vitamin K1 content. The vitamin K1 contained in these intravenous lipid emulsions is substantial and may have great impact on the vitamin K status of the recipient.

We then compared the prospective culture results with those of the actual blood culture. Three sequentially drawn aliquots of blood were aspirated from the central venous catheter and cultured. The culture results of the second aliquot were comparable to those of the third (the portion usually cultured) in overall sensitivity (94.4%), specificity (94.9%), and positive predictive value (80.9%). Thus, the amount of blood that must be discarded (infants: 0.3 mL; children: 1.0 mL) before one can obtain an accurate central venous catheter culture is less than was previously thought.

The scarcity of the data is due, in part, to the destructive nature of total body analyses normally required for the classical chemical approach. To help determine such data for infants, we have developed a neutron activation facility for nondestructive postmortem analyses. The system consists of a multisource (AmBe)-Am241 irradiator and a multidetector NaI(Tl) whole body counter. The total body contents of K, Ca, P, Na and Cl are determined. Postmortem examinations have been performed in twelve infant cadavers. These results are compared with those of the reference fetus.

They are potentially useful as the forb component of seeding mixtures for rangeland improvement in the western states. However, the degree of acceptability of globemallow forage to livestock has not been well established. We tested 13 globemallow accessions representing 4 species and compared their utilization by sheep (Ovis aries) with that of crested wheatgrass [Agropyron cristatum (L.) Gaertn. X A. desertorum (Fisch.) Schult.] and alfalfa (Medicago sativa L.) during fall 1988 and 1989, and spring 1990 and 1991. Alfalfa consistently produced more forage per plant than wheatgrass or globemallows, and a greater portion of the alfalfa was eaten than of the other species. Sheep utilized wheatgrass more than globemallows in the fall, but the converse was true during spring pasturing. Over the 4 years, sheep ate similar proportions of wheatgrass and individual globemallows. The percentage of S. coccinea (Pursh) Rydb. forage consumed equaled that of crested wheatgrass or alfalfa in the fall but did not equal the percentage of alfalfa consumed in spring. However, S. coccinea produced much less total forage than the other species evaluated. Pre-grazing plant dry weight, dry matter content, and the occurrence of rust caused by Puccinea sherardiana Korn were negatively associated with globemallow utilization. Over-winter mortality of grazed globemallow exceeded that of ungrazed plants. Crested wheatgrass and alfalfa stands were not reduced by grazing. Globemallows are acceptable, but not highly preferred, forbs which can be seeded in environments where alfalfa and other more desirable species are not adapted.

Little is known of their nutritional value for ungulates. We measured element concentrations in representative globemallow species and evaluated their adequacy for livestock nutrition. We also correlated forage selection by sheep (Ovis aries) with element concentrations. Alfalfa (Medicago sativa L.), crested wheatgrass [Agropyron cristatum (L.) Gaertn. X A. desertorum (Fisch.) Schult.], and 13 accessions of globemallows [S. coccinea (Pursh) Rydb., S. grossulariifolia (H. & A.) Rydb., S. munroana (Dougl) Spach., and S. parvifolia A. Nels.] were transplanted into replicated grazing trials in southern Idaho. Herbage was sampled and the pastures were grazed by sheep in the fall of 2 years and in the spring of the following 2 years. Concentrations of Ca and Mg in crested wheatgrass were lower than in forbs. Differences between seasons were greater than the differences among globemallow species. Forage selection ratios were positively associated with the N concentration of globemallow leaves and with the Ca:P ratio of globemallow stems but were negatively associated with stem Zn concentrations. Herbage from pastures containing crested wheatgrass with globemallows and/or alfalfa would meet the dietary element requirements of beef cattle (Bos taurus) and sheep.

We used long-interval time-lapse photography to study frequency and intensity of defoliation of western wheatgrass (Pascopyrum smithii [Rydb.] A. Love) and blue grama (Bouteloua gracilis [H.B.K.] Lag. ex Steud.) tillers under continuous season-long and time-controlled short-duration rotation grazing by steers at 2 stocking rates. Frequency, intensity, and variability of defoliation of both grasses were similar under both grazing systems. Western wheatgrass tillers were grazed more frequently under heavy than under moderate stocking, and in 1990 more herbage was removed the second time a tiller was grazed under heavy stocking. Blue grama tillers were grazed more frequently under heavy than under moderate stocking in both years under rotation grazing, but only in 1990 under continuous grazing; more herbage was removed under heavy stocking the second time a tiller was grazed. Under heavy and moderate stocking, respectively, 19% and 36% of western wheatgrass tillers and 42% and 54% of blue grams tillers were ungrazed throughout the grazing season. Few western wheatgrass tillers were grazed more than twice, and few blue grama tillers were grazed more than once. Stocking rates have much greater potential than grazing systems for altering frequency and intensity of defoliation and subsequent changes in botanical composition of range plant communities. Results of grazing studies support this conclusion. C1 UNIV WYOMING,DEPT RANGE MANAGEMENT,LARAMIE,WY 82071.

To examine why change has not occurred in this area, this paper explores the historical development of the range condition concept in the context of the life cycle of a scientific theory. Dyksterhuis' contribution and significant impact on the concept of range condition reflects the close tie between an underlying ecological theory of the time, that grazing alters species composition in a predictable manner, and his field method which measured that change as the difference between the relative composition of the current and climax vegetation. The evolution of the range condition concept differs in significant ways from the evolution of scientific theories such as Clements' climax theory. These differences include the lack of an intellectual center for research on range condition and reflect the institutionalization of technology to measure range condition. Success of alternative models for range condition may require an underlying theory linked to a field method to successfully capture the consensus of the range community.

Coefficients range from 0 (indicating a complete lack of similarity) to 1 (indicating complete similarity). Similarity is classed as low (0 - 0.25), moderate (0.26 - 0.50), high (0.51 - 0.75), or full (0.76 - 1). Study of time-goal coefficent graphs is suggested for deciding whether trend is up, down, or static. Defining goals and lack of statistical tests are major limitations.

A linear, quadratic regression was used for model development and testing, and analysis was by general linear hypothesis testing. All factors except topographic position were significant; however, only phenological development was useful in a general model for estimating utilization from the percentage of height remaining. This factor was best expressed in 3 leaf-classes of 2-4, 5-6, and 7-10 leaves per tiller. Thus, height-weight relationships can be improved as a biomass predictor if separate regressions are used for these 3 phenological classes. C1 USDI,BUR LAND MANAGEMENT,GLENWOOD SPRINGS,CO 81602.

Mesquite (Prosopis velutina Woot.) on the watershed of 1 headcut of each pair was killed with diesel oil. Densities of perennial grasses and shrubs, shrub cover, surface erosion, headcut advance, and gully depth were recorded at 3-year intervals, 1974-1986. Four of the watershed pairs were in pastures grazed yearlong: 4 were in Santa Rita rotations. Each grazing schedule included 2 watershed pairs that were about 200 m higher in elevation than the other 2. In 1974, before mesquite was killed, perennial grass densities were low with little difference between assigned conditions. By 1977 perennial grass density was greater where mesquite was killed than on untreated watersheds and was greater at upper elevations. Lehmann lovegrass (Eragrostis Lehmanniana Nees.) made up almost all of the grass density increase at the upper elevation. Native perennial grasses, which were largely replaced by Lehmann lovegrass at the upper elevation, accounted for almost all of the gain at the lower elevation. Lower density (P less-than-or-equal-to 0.05) on low elevation rotation grazed watersheds in 1986 was the result of summer drouth in 1985 and 1986 that coincided with March-October grazing in 1986. Soil loss (mm) during each 3-year period was lower at headcut-soil surface grids where mesquite was dead. Advances in headcuts and changes in gully depth showed similar trends. On the 4 pairs of watersheds that were equipped to measure runoff, there was more total runoff per millimeter of rainfall where mesquite was alive than where mesquite was killed.

Seed harvested from native prairies can be used to revegetate highly erodible or marginal cropland and degraded rangeland if adequate quantities of seed can be produced. The effect of spring burning, fertilization, and atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine] on big bluestem (Andropogon gerardii Vitman var. gerardii Vitman) and indiangrass [Sorghastrum nutans (L.) Nash] reproductive stem density and seed production was determined in 9 tallgrass prairie environments (each year by site was considered a unique environment). Studies were conducted at tallgrass prairies near Bloomfield, Lincoln, and Virginia, Nebr., from 1987 through 1990. Atrazine was applied at rates of 0 and 2.2 kg a.i. ha-1 in mid-spring. Fertilizer rates applied in late spring were 0 and 110-0 kg N-P ha-1 at Lincoln in 1987, 0 and 110-22 kg N-P ha-1 at Bloomfield in 1987 and all sites in 1988, and 0 and 67-22 N-P kg ha-1 at all sites in 1989 and 1990. Improvement practices increased stem density of big bluestem in 5 environments and indiangrass in 4 environments. Number of germinable seed produced by the grasses was influenced by treatment only in 1987 and 1990 when precipitation amounts were above or near the long-term average. In 1987, atrazine increased indiangrass germinable seed number from 202 to 481 seed m-2 at Bloomfield. At Lincoln in 1987, the combined effects of fire, fertilizer, and atrazine increased the number of germinable indiangrass seed to 2,517 seed m-2 as compared to 331 seed m-2 produced on areas that had not been treated. In 1990, burning in mid-May increased big bluestem seed number from 52 to 125 germinable seed m-2 at Virginia, and fertilizer increased big bluestem seed number from 333 to 724 seed m-2 at Lincoln. The tallgrasses did not produce germinable seed in 1988 and 1989, presumably because of drought conditions that persisted both years. Improvement practices evaluated in this study increased native grass seed production when precipitation was adequate. However, no single treatment or combination of treatments reliably or consistently increased the number of seed produced and the absolute amount of seed produced on native prairies was low.

We collected data at 85 nest trees and made comparisons of 62 paired nest- and randomly-selected trees. More nests (92%) were in Douglas-fir trees (Pseudotsuga menziesii) than expected in comparison to other tree species in the stand. Most nest trees occupied either dominant or codominant canopy positions, and were typically alive and fully intact. Nest trees ranged from 66-700 yr of age; the median age was 137 yr. Nest trees on south-facing slopes were significantly larger in diameter and older than those on north-facing slopes. Trees with cavity and broken-top platform nests were significantly larger in diameter and older than trees that supported other types of nests. Nests originally made by Northern Goshawks (Accipiter gentilis) were the most common nest type used by Spotted Owls (55.3%); other nests were located in mistletoe growth (24.7%), in cavities (10.6%), on broken-tops (5.9%), and on large branches (3.5%). The relatively young age and smaller diameter of nest trees used by Spotted Owls in the eastern Cascades is consistent with the characteristics of stands used for nesting and is likely a result of the fire history of this region. The presence of mistletoe clumps and goshawk nests may facilitate occupancy of younger stands that otherwise lack nesting structures.

Ovulation rates (determined via laparoscopy) following the first oestrus were 1.3, 3.3, 2.0 and 2.1 for LF, HF, CF and CAM groups, respectively. In a second experiment, jugular and utero-ovarian venous blood samples were collected simultaneously from seven Rambouillet crossbred ewes during the mid-luteal phase of an oestrous cycle to determine whether the ovary is a major source of blood IGF-1. In the first experiment, plasma IGF-1 concentrations increased (P < 0.05) between days 0 and 3, and then decreased (P < 0.05) between days 4 and 8 in all groups. IGF-1 concentrations increased again at the subsequent oestrus. There was no significant difference in plasma IGF-1 between HF and LF ewe lambs. Overall, plasma IGF-1 was lowest (P < 0.05) in CAM and highest in CF ewe lambs at all stages. Plasma IGF-1-binding protein activity did not vary with stage of cycle or differ (P > 0.10) among genotypes. Among LF, HF and CF ewe lambs, ovulation rate was not correlated with plasma IGF-1 or IGF-1-binding protein activity. In the second experiment, serum concentrations of IGF-1 in jugular (174 +/- 38 ng ml-1) and utero-ovarian (188 +/- 43 ng ml-1) venous blood did not differ (P > 0.10) but were highly correlated (r = 0.96). We conclude that (i) plasma concentrations of IGF-1 increase during oestrus in cyclic ewes, (ii) plasma concentrations of IGF-1 are influenced by genotype in sheep but are not genetically associated with ovulation rate, (iii) plasma IGF-1-binding protein activity is not influenced by stage of cycle or genotype in sheep, and (iv) the ovary does not appear to be a major source of blood IGF-1.

Blood was collected on 3 days per week and faeces on 5 days per week from four unanaesthetized cyclic female baboons, consecutively fed three diets of 5, 10 and 20% fibre for 90 days per diet. A 2 day lag time was detected before progesterone in the blood appeared in the faeces, regardless of diet (mean correlation was 0.62, P = 0.002). Increased dietary fibre had a negative effect on progestogen excretion (P < 0.004). Correspondence between blood and faecal progestogens was consistently greatest and the effect of dietary fibre least when faecal progestogens were expressed g-1 dry faeces. Several means of indexing faecal steroid excretion rates were examined including dehydroepiandrosterone (DHEA) and a number of byproducts of cholesterol metabolism. The cholesterol metabolite, cholestanone, was positively correlated with dietary fibre (r = 0.27; P < 0.04). Multiplying faecal progestogen concentration by the cholestanone g-1 dry faeces concentration increased the correlation between serum and cholestanone-indexed faecal progestogens (r = 0.78, P = 0.0001) compared with nonindexed progestogens (r = 0.71, P = 0.0001). We conclude that expressing faecal progestogens g-1 dry faeces may be sufficient and the most cost-effective method for controlling for most dietary effects when the objective is monitoring longitudinal endocrine status in baboons.

Surface contamination of males was transferred to adult females during copulation and larval food was subsequently contaminated by females during oviposition as well as by other adult activities. Both the F1 and F2 generations of larvae acquired patent infections of IMMGV, resulting in 60% and 50% mortality, respectively. Concurrent introduction of both sexes into the exposure room compared unfavorably with trials in which males were exposed for 24 hr before females were added. Only 16% mortality resulted in the F1 progeny when males and females were exposed simultaneously. Cadaver feeding was found not to be significant. Although incidence of infection was not high when both sexes were introduced simultaneously, the results confirm previous indications that autodissemination may have potential for limited control of P. interpunctella.

To generate a carotenoid database, an artificial intelligence system was developed to evaluate data for carotenoid content of food in five general categories, namely, number of samples, analytic method, sample handling, sampling plan, and analytic quality control. Within these categories, criteria have been created to rate analytic data for beta-carotene, alpha-carotene, lutein, lycopene, and beta-cryptoxanthin in fruits and vegetables. These carotenoids are also found in human blood. Following the evaluation of data, acceptable values for each carotenoid in the foods were combined to generate a database of 120 foods. The database includes the food description; median, minimum and maximum values for the specific carotenoids in each food; the number of acceptable values and their references; and a confidence code, which is an indicator of the reliability of a specific carotenoid value for a food. The carotenoid database can be used to estimate the intake of specific carotenoids in order to examine the association between dietary carotenoids and disease incidence.

The database was used to estimate intakes of specific carotenoids for 19- to 50-year-old women (n = 1,102), using food consumption data obtained from dietary recalls in the US Department of Agriculture Continuing Survey of Food Intake by Individuals, 1986. The major contributors of alpha-carotene were carrots consumed as a single food or as an ingredient in multicomponent foods. Carrots, cantaloupe, and broccoli were the main sources of beta-carotene. Orange juices and blends, oranges, and tangerines were important contributors of beta-cryptoxanthin. Tomatoes and tomato products consumed as single foods or as ingredients in multicomponent foods provided most of the dietary lycopene. Contributors of lutein + zeaxanthin included collard, mustard, or turnip greens; spinach; and broccoli. The per capita consumption of total carotenoids (the sum of the five specific carotenoids) among these women was approximately 6 mg/day.

To compare the relative potential of these interventions to reduce frailty and fall-related injuries, all sites share certain descriptive (risk-adjustment) measures and outcome measures. This article describes the shared measures, which are referred to as the FICSIT Common Data Base (CDB). The description is divided into four sections according to the four FICSIT committees responsible for the CDB: (1) psychosocial health and demographic measures; (2) physical health measures; (3) fall-related measures; and (4) cost and cost-effectiveness measures. Because the structure of the FICSIT trial is unusual, the CDB should expedite secondary analyses of various research questions dealing with frailty and falls.

Reversible components of the muscle weakness of aging include underuse syndromes and undernutrition, both of which are prevalent in nursing home populations. The Boston FICSIT study is a nursing home-based intervention to improve muscle strength through progressive resistance training of the lower extremities and/or multi-nutrient supplementation in chronically institutionalized subjects aged 70-100. Baseline measurements of falls, medical status, psychological variables, functional status, nutritional intake and status, body composition, muscle mass and morphology, muscle function, and gait and balance are taken. The nursing home residents are then randomly assigned to one of four treatment groups for 10 weeks: (1) high intensity progressive resistance training of the hip and knee extensors 3 days per week; (2) multi-nutrient supplementation with a 360-kcal high carbohydrate, low fat liquid supplement every day; (3) a combination of groups (1) and (2); and (4) a control group. Both non-supplemented groups receive a liquid placebo every day, and both non-exercising groups attend three sessions of ''leisure activities' every week in order to control for the attentional aspects of the exercise and nutritional interventions. At the end of the 10-week period, all baseline measurements are re-assessed. C1 TUFTS UNIV,HEBREW REHABIL CTR AGED,BOSTON,MA 02111. BRIGHAM & WOMENS HOSP,DIV GERONTOL,BOSTON,MA 02115.

Direct alpha to beta conversion involves lateral disruption of fatty chain packing to generate side-chain character typical of the beta-form. Such disruption, which could contribute to fat bloom, allows additional molecular movement and shifts in molecular mechanics energy (MME) that may approximate thermal changes observed by differential scanning calorimetry during alpha to beta transformations. Energy calculations at 100 points throughout each transformation identified plausible conversion routes. A two-stage conversion, alpha to either of two stereospecific beta'-forms bent at glycerol followed by subsequent conversion to beta, showed less chain movement and more favorable MME than direct alpha to beta conversion. The preferred path, based on energy profiles of each conversion, involves a beta'-D form and rotation of carbonyl to alpha-carbon bonds in chain #2 and a side chain (chain #3).

The two simultaneously occurring reactions, interesterification and hydrolysis, were followed by high-performance liquid chromatography of altered glycerides and by gas-liquid chromatography of liberated free fatty acids. The enzymes used in these studies were immobilized lipases that included either a 1,3-acyl-selective lipase or a cis-9-C18-selective lipase. The degree of hydrolysis of the fat/oil mixtures was dependent upon the initial water content of the reaction medium. The extent of the interesterification reaction was dependent on the amount of enzyme employed but not on the reaction temperature over the range of 50-70-degrees-C. Changes in melting characteristics of the interesterified glyceride mixtures were followed by differential scanning calorimetry of the residual mixed glycerides after removal of free fatty acids. Interesterification of the glyceride mixes with the two types of enzymes allowed for either a decrease or increase in the solid fat content of the initial glyceride mix.

A one-to-one mixture of soybean and meadowfoam or rapeseed oil produces a factice that has similar physical characteristics as factice produced from 100% meadowfoam or rapeseed oils. In addition, meadowfoam oil and rapeseed oil act as accelerators when mixed with castor or jojoba oils. White factice productions from soybean oil can also be improved when mixed with meadowfoam or rapeseed oils.

As muskmelon fruit progress from immaturity to maturity, and with storage of mature fruit at 4 or 24C, increased permeability of the hypodermal-mesocarp tissue occurs coincident with an increase in the saturation index of the plasma membrane phospholipids. Buoyant density of the plasma membrane from hypodermal mesocarp tissue increased from 1.13 to 1.14 g.cm-3 during fruit maturation. Vanadate-sensitive ATPase (EC 3.6.1.35) activity was highest in mature fruit at harvest. After 10 days of storage, vanadate-sensitive ATPase activity was much lower in fruit kept at 24C than in those kept at 4C. The decrease in vanadate-sensitive ATPase activity in fruit stored at 24C was correlated with increased hypodermal-mesocarp membrane permeability. We suggest that biochemical changes affecting the lipid matrix of the plasma membrane influence fruit membrane permeability and possibly muskmelon storage life.

The method allocates experimental units to blocks on the basis of the values of a variable, x, that is known to be correlated with the response, y. We call this allocation method ''predictor sort sampling.'' We demonstrate that the associated paired T analysis recommended in statistical texts is deficient if the sample size is small and the correlation between x and y is high. We temper this criticism of standard statistical intuition with a proof that the approach is asymptotically correct. In a related development we show that a modified pooled T approach can be taken to this data with a resultant increase in power. We compare these approaches to an analysis of covariance approach and discuss the advantages of each. Finally, we warn against the intuitively attractive but incorrect power calculations that are likely to be performed in association with a predictor sort experiment.

Highest resistance was to tetracycline (45%), streptomycin (41%), sulfisoxazole (19%), gentamicin (10%), and trimethoprim/sulfamethoxazole (8%). Additional isolates of S typhimurium, heidelberg, agona, and enteritidis were selected from the sample of 1,824 isolates for testing because of the high frequency with which these 4 serotypes are isolated from human patients. The highest frequency of resistance among 104 isolates of S heidelberg, 92 isolates of S typhimurium, and 30 isolates of S agona was to streptomycin (33 to 57%), sulfisoxazole (33 to 50%), tetracycline (26 to 50%), and gentamicin (13 to 40%); 51 to 63% of these isolates were resistant to 1 or more agents and 37 to 59% were resistant to 2 or more agents. Resistance to ampicillin among these 3 serotypes was uncommon (0 to 4%). In contrast, 15 of 19 tested isolates (79%) of S enteritidis were resistant to ampicillin and 13 of the 19 isolates (68%) were resistant only to ampicillin. This pattern of resistance was associated with a specific bacteriophage type and indicated the potential role of bacterial clones in determining the frequency and patterns of antimicrobial resistance in populations of broiler chickens. Resistance to gentamicin and trimethoprim/sulfamethoxazole was higher than that previously reported and is of public health concern because of the frequency with which these drugs are used to treat bacterial infections in human patients.

The fumonisins are carcinogenic in laboratory rats, and cause acute toxicity of domestic animals that mimics field cases of disease attributed to contamination of feed by F. moniliforme. These include both equine leukoencephalomalacia and porcine pulmonary edema. Fusarium moniliforme contamination of com consumed by humans in certain areas of the world is associated with higher than average incidence of esophageal cancer and fumonisins may be responsible. Analytical methods have been developed for fumonisins, but improvements are needed so that more accurate, less expensive, and more rapid assays of food and feedstuffs can be done. Fumonisins are structurally similar to sphingosine, and may exert their biological activity through their ability to block key enzymes (sphinganine- and sphingosine-N-acyltransferases) involved in sphingolipid biosynthesis. Much more research is needed to define the extent to which this mycotoxin adversely affects the food supply, and its involvement in animal and human diseases.

The etiological agent, rinderpest virus (RPV), is a member of the family Paramyxoviridae and the genus Morbillivirus. Immune responses to both the hemagglutinin (H) and the fusion (F) antigens of morbilliviruses play an important role in the prevention of infection, and only attenuated live vaccines have been shown to provide protective immunity against the group. The lack of protection with inactivated vaccines has been attributed to the denaturation of the F glycoprotein of the virus. Our previous study, however, demonstrated complete protection of cattle vaccinated with infectious vaccinia virus recombinants expressing the H (vRVH) or F (vRVF) protein alone, even in the presence of only 4 U of serum-neutralizing (SN) antibody to RPV (T. Yilma, D. Hsu, L. Jones, S. Owens, M. Grubman, C. Mebus, M. Yamanaka, and B. Dale, Science 242:1058-1061, 1988). We have constructed recombinant baculoviruses that express the F (F(b)) and H (H(b)) glycoproteins of RPV. Furthermore, we have analyzed the immune responses of mice and cattle to these antigens. Cattle vaccinated with F(b) or H(b) or a mixture of both antigens were not protected from challenge inoculation with RPV, even when the SN titer was greater than in cattle vaccinated with vRVF alone. This lack of protection, in the presence of SN antibody, would indicate that live attenuated and recombinant vaccines induce immune responses necessary for protection (e.g., cell-mediated immunity) that are not generated by subunit or inactivated whole-virus vaccines.

Immunofluorescence analyses showed that E appeared to be localized in the endoplasmic reticulum of cells infected with JEV, vP829, or vP658. However, reactivity with monoclonal antibodies and behavior in Triton X-114 indicated that E produced in the absence of prM behaved abnormally. Furthermore, E produced in the presence of prM by recombinant vaccinia viruses could be incorporated into flavivirus pseudotypes, whereas E synthesized in the absence of prM could not. These results demonstrate that cosynthesis of prM is required for proper folding, membrane association, and assembly of the flavivirus E protein.

Five new species, viz. H. amaurodermatis, H. lanceolatus, H. mycophilus, H. pergamenus, and H. sympodiophorus are described. Thirteen species have a proven anamorph. No anamorphs have been linked to six species.

The patterns of branching, arrangement of conidiogenous loci, or the number and arrangement of conidia on the conidiogenous cell, which is a reflection of proliferation of the conidiogenous cell, are not significant as generic determinants when seen in the light of the apparent phylogenetic homogeneity of their teleomorphs. Most of the species that are anamorphs of Hypomyces are placed in Cladobotryum. The anamorph of H. chrysostomus is referred to Acremonium.

As a consequence, the boundaries of Hymenogaster became inflated even beyond Vittadini's original broad concept, and the genus came to represent more than one phylogenetic line. This paper clarifies the generic limits of Hymenogaster and challenges a prevailing notion that Hymenogaster represents the hypogeous member of a phylogenetic line linked through Thaxterogaster to Cortinarius. On the basis of both macromorphological and micromorphological characters of basidiomes, Hymenogaster sensu stricto is redefined. Selected species are allocated to four new genera: Cortinomyces, Descomyces, Quadrispora, and Timgrovea. A key to these genera is provided. Four of the eight original Vittadini species are excluded from Hymenogaster H. rufus (type lost), H. citrinus (to Gautieria), H. luteus (to Hysterogaster), and H. niveus (to Cortinomyces). The remaining four species have large, thick-walled, broad ellipsoid to fusiform spores bearing a large, cupped hilar appendix and are designated as the core of Hymenogaster since they include the type species H. bulliardi. Also included with the type are H. olivaceus, H. lycoperdineus and H. griseus. The relationships of these Hymenogaster species to other fungi are not known, but the spore type does not indicate a close relationship with Cortinarius and Thaxterogaster. The remaining Vittadini species H. niveus is placed in the new genus Cortinomyces by virtue of its smaller, warty spores. Cortinomyces is largely distinguished from Hymenogaster by having cortinarioid spores. Numerous other characters, such as peridial pigments and structure, suggest that Cortinomyces fits into a phylogenetic series with Thaxterogaster and Cortinarius. Hymenogaster cribbiae, H. effodiendus, H. luteus (non Vittadini), H. niveus, H. purpureus, H. violaceus, and H. viscidus are recombined to Cortinomyces. Descomyces has distinctive spore morphology (e.g., a smooth rostrum and ornamentation embedded in the perisporium) and peridium structure (e.g., two layered and with swollen cells). This peculiar combination of peridial and spore characteristics also occurs in Setchelliogaster and in Descolea. It is proposed that Descomyces (with hypogeous angiocarpic basidiomes and a loculate hymenium) represents the truffle-like form in a phylogenetic series that also includes Setchelliogaster (subhypogeous, pseudoangiocarpic basidiomes) and Descolea (epigeous bivelangiocarpic basidiomes and a lamellate hymenium). Further supporting evidence of this relationship is obtained from examination of mycorrhizae and axenic cultures of these fungi. Species transferred to Descomyces include H. albellus, H. albus, and H. javanicus. H. albellus and H. albus are maintained as separate species, the former is considered to include collections having a polycystoderm (epithelium). Quadrispora includes species with assymetrical spores that adhere in tetrads after release from the basidium. H. oblongisporus is recombined into the new genus, and Q. musispora is described as new. The relationships of Quadrispora to other fungi are not known. Finally, Timgrovea is proposed to accommodate species with reticulate spores, T. reticulatus, T. macrosporus, T. subtropicus, and T. ferrugineus from Australia, and T. kwangiensis from China. The relationships of Timgrovea probably occur outside the Cortinariaceae. A possible relationship of Timgrovea to the Boletaceae is discussed. C1 US FOREST SERV,FORESTRY SCI LAB,CORVALLIS,OR 97331.

The purpose of this study was to assess the effects of a synthetic trivalent Cr-nicotinic acid (NA) supplement on insulin controlled variables in athletes. Thirty-four college-age male bodybuilders (BB) were randomly assigned to three groups: placebo (P), n=11; 200 mug Cr-1.8 mg NA (1X), n=12; or 800 mug Cr-7.2 mg NA (4X), n=11. Supplements were ingested daily for 8 weeks and training was controlled. Twelve hr fasting insulin, glucose, total cholesterol (TC), triglyceride, HDL-cholesterol, TC:HDL, LDL-cholesterol, and one hr post-challenge insulin and glucose values were determined at pre- and post-supplementation periods. All pre-supplementation values were within normal ranges. ANOVAs revealed two significant interactions. Mean TC in the P group increased from 139.9 to 153.4 mg/dl, yet decreased from 147.9 to 126.8 mg/dl and 159.2 to 131.3 mg/dl in the 1X and 4X groups, respectively (p<.03). Mean TC:HDL increased from 3.02 to 3.73 in the P group and decreased from 3.62 to 3.37 and 3.43 to 3.27 in the 1X and 4X groups, respectively (p<.04). Differences in insulin concentration and glucose tolerance, markers of insulin function, were not significant between groups. Since some lipid parameters were altered, yet glucose tolerance was unchanged, these data support independent effects of Cr on glucose and lipid metabolism. C1 AUBURN UNIV,AUBURN,AL 36849.

After five weeks, rats consuming diets containing less than 5.2 mug Cu/g exhibited reduced liver Cu concentrations and plasma ceruloplasmin amine oxidase activity. Anemia, however, was present only in rats consuming diet containing 0.4 mug Cu/g. Cytoskeletal myosin heavy chain (MHC) content in platelets prior to and 45s following activation with 2 nM thrombin tended to increase with decreasing dietary Cu, but significant (P<0.05) differences occurred only between rats fed diets containing 0.4 and 5.2 mug Cu/g. Similarly, when platelet dense granule secretion was assessed by measuring the rate of ATP secretion and the total amount of ATP secreted following stimulation with 2 nM thrombin, significant differences occurred only between rats fed diets containing 0.4 and 5.2 mug Cu/g. Because rats consuming diet containing 0.4 mug Cu/g became anemic, the alteration of platelet responses in these rats may have been a direct result of anemia rather than copper deficiency. However, neither cytoskeletal MHC content nor dense granule secretion were altered in rats with iron deficiency anemia. These results indicate that moderate copper deficiency has little effect on cytoskeletal remodeling and dense granule secretion in thrombin-stimulated platelets and that anemia per se is most likely not a causative factor in the altered platelet responses associated with severe copper deficiency.

Less stressful delivery may be related to the ability to maintain pregnancy without the ovary, a characteristic of the human; or it may be due to the small size of premature fetuses. To determine whether difficult parturition would result if a full-size fetus were delivered at term, 14 ewes were given a low Zn diet for the last half of pregnancy. Each restricted-intake ewe (+ZnRI) received Zn-supplemented drinking water and diet proportional to that eaten by a weight-matched unsupplemented ad libitum-fed ewe (ZnD). One ZnD ewe delivered day 143; the remaining ewes delivered at term (approximately 1 50 days). Two of 5 ZnD single lambs survived compared to 3 of 3 +ZnRI. One of 4 ZnD twin lambs survived compared to 3 of 8 +ZnRI. Problems of ZnD included prolonged labor, pregnancy toxemia, meconium in airways, and retained placentas. Activities of plasma angiotensin-converting enzyme and alpha-D-mannosidase with added Zn in vitro were significantly greater in ZnD and may be useful as indicators of Zn status.

To prevent excess iron from damaging cells, it is stored in ferritin, which consists of a shell of protein subunits of two related types, H (heavy) and L (light), surrounding a cavity in which the iron can be deposited. In order to prepare for a rapid increase in ferritin in response to a rise in cellular iron, a large number of dormant ferritin mRNAs are accumulated in the cytoplasm. These can be rapidly activated to yield a large population of ferritin subunits. Regulation is achieved through a 28-nucleotide ''stem-and-loop'' structure near the beginning of the H- and L-ferritin mRNAs. When this structure is associated with a binding protein (iron regulatory element binding protein, IRE-BP), translation of the ferritin mRNA cannot proceed. However, when intracellular iron accumulates, IRE-BP releases its hold and translation of the mRNA then takes place. IRE-BP has been identified as a cytosolic form of aconitase, containing several fourfold iron-sulfur clusters. Within each cluster one iron atom is labile; this may be the mechanism by which IRE-BP responds to intracellular iron levels. Finally, transcription of the L- and H-genes shows that L is preferentially transcribed in response to increased iron intake, whereas H responds to cell differentiation and other factors. More work is needed to define independent transcription of the individual genes, including regulation of components other than the 28-nucleotide segment.

Currently, both programs select lines for advanced testing based on their performance at a single location within each state. If the genotype X environment interaction does not affect early generation performance between these two environments, then similar crosses and lines within crosses would be selected in each state. The purpose of this study was to examine the G x E interaction effect on genotypes grown in these two environments. Yield and market grade characteristics were determined each of 2 years at the two selection sites for nine crosses represented by eight lines per cross in the F4 and F5 generations. Significant differences for all traits occurred among cross populations and among lines within populations. Crosses interacted with the environment for all traits, while lines within crosses interacted with the environment for all traits except yield. The crosses interacted with the environment because their rankings of performance changed in the different environments. In spite of a significant cross x environment interaction, the three best performing cross populations were identified as being high yielding at both locations. An examination of genetic components of variance for crosses and lines within crosses for the different environments indicates that superior crosses can be identified at a single location. However, individual lines within crosses should be selected on mean performance across environments (years and locations).

For this reason, we studied the effects of 6 weeks of a zinc-deficient diet (ZD1; 1 mug zinc per g diet), pair-feeding (PF), and marginal zinc deficiency (ZD6; 6 mug zinc per g diet) compared to a control diet (36 mug/g zinc) on the conversion of prepro-TRH to TRH in epididymides, testes, prostate, pancreas, and heart of young adult, male Sprague-Dawley rats. In the epididymis, severe zinc deficiency (ZD1 diet) reduced TRH and TRH-like peptides to undetectable levels. In ZD6 animals, TRH was selectively inhibited 80%, while pair-feeding increased all of these peptide levels compared to controls. A similar effect of zinc deficiency on the TRH precursor peptides was observed. A quantitative loss of TRH from the testes of ZD1 was also observed. Zinc deficiency results in a substantial reduction in body weight and testosterone production in male rats. Exogenous testosterone (T) supplementation of ZD1 rats resulted in a selective increase in the TRH concentration of the epididymis but not of the heart. The change in steady-state levels of TRH precursor peptides in the hearts of the ZD1 + T rats was consistent with a reduction in the activity of the zinc-dependent carboxypeptidase H enzyme. We conclude that severe zinc deficiency inhibits TRH biosynthesis in reproductive tissues of the male rat due to the combined effects of hypogonadism and inhibition of the zinc-dependent carboxypeptidase H.

The beta-galactosidases had pI values of 5.0, 5.1 and 5.2. and molecular weights of 41, 49 and 54 kDa, respectively. There was a partial degradation of pectin resulting in the release of monomeric galactose upon treatment with avocado beta-galactosidase. This degradation resulted in increased pectin solubility and decreased apparent average molecular size as determined by microfiltration and gel permeation by high-performance liquid chromatography. The increase in solubility was due, in part, to an apparent decrease in the ability of pectin molecules to aggregate together.

(Hemiptera: Pentatomidae), are successfully attacked by Trissolcus basalis (Woll.) (Hymenoptera: Scelionidae) and are recognized as hosts by a secretion applied to the egg chorion. This secretion is produced by the follicular cells in the proximal region of the ovariole of the female pentatomid and functions as an adhesive for attaching the eggs to the oviposition substrate. The adhesive and kairomone activity could be partially removed with water. This water extract elicited host recognition behaviour in T. basalis when applied to glass beads which stuck together as the extract dried. The adhesive and kairomonal activity was removed completely with acetone since acetone-washed host eggs were not recognized by T. basalis. Application of the acetone extract to glass beads stimulated ovipositional probes by T. basalis. The adhesive appeared to be composed of a mucopolysaccharide-protein complex.

Sodium citrate was added to freshly collected bovine blood to give final concentrations of 5-100 mM while sodium heparin was used in concentrations of 10-70 USP units/ml blood. Small cages containing five male and ten female newly emerged laboratory-reared horn flies were maintained for 8-10 days on these blood samples, and mortality and egg production recorded daily. Results showed that as blood citrate concentration was increased, egg production decreased logarithmically. At sodium citrate concentrations of 50 mM and above, severe impacts on egg production and adult horn fly survival occurred. Although no dose-related response of egg production to increasing heparin concentrations was noted, the 25 USP units heparin/ml blood treatments gave the largest egg production, yielding approximately 28% more eggs than any other treatment. Since citrate is a known chelator of divalent metal cations, the effects of supplemental cation additions to citrated blood were tested for their ability to reverse the egg production decrease seen at 50 mM sodium citrate. Blood samples containing 50 mM sodium citrate were supplemented with CaCl2, calcium lactate, CuCl2, cupric acetate, FeCl3, ferric citrate, MgCl2, magnesium acetate, MnCl2, ZnSO4, EGTA or EGTA plus calcium lactate, each at 1 mM except EGTA which was used at 2.5 mM. The magnesium acetate supplement and the combination of calcium lactate plus EGTA resulted in a statistically significant increase in egg production (P less-than-or-equal-to 0.05).

The overall composition of four different classes of phenolic compounds absorbing at 285 nm (flavone/ols, flavanones. coumarins/cinnamic acid derivatives and psoralens) for the Rutaceae species and cultivars were determined in leaf, flavedo, albedo and juice vesicle tissues. Percentages and concentrations of 11 flavanone glycosides, three flavone glycosides and one flavonol glycoside were determined. Most Citrus species can be classified by their flavonoid glycosylation pattern as either predominately neohesperidosyl or predominately rutinosyl. Species and cultivars containing mainly neohesperidosyl flavanones also contained neohesperidosyl flavones. Similarly, species and cultivars containing rutinosyl flavanones contained rutinosyl flavones.

The predominant protein in these rubber particles is a large hydrophobic glycoprotein (termed LPR for large protein from rubber particles), with an apparent monomeric M(r) of 376000 on SDS-PAGE. A M(r) of 750000 was determined with native PAGE, indicating that LPR probably exists as a dimer. Antibodies raised to purified LPR recognized blotted intact F. elastica rubber particles, as well as LPR, demonstrating that LPR is situated at or near the surface of the particles. Anti-LPR antibodies also recognized enzymatically active rubber particles and rubber particle proteins from two other rubber-producing plants, Hevea. brasiliensis and Parthenium argentatum. This indicates that the rubber particles of all three rubber-producing species contain proteins with common antigenic determinants. Large proteins, similar in size to LPR, were found in preparations of rubber particles from H. brasiliensis and P. argentatum. These results are the first demonstration that rubber particles from different species contain similar proteins that may share common functions in rubber biosynthesis and/or rubber particle structure.

At the beginning of the chase period, all radioactivity was recovered in the basic (amino acid-containing) fraction of pedicel extracts. Radioactivity recovered in the acid (organic acid-containing) fraction increased steadily from 0 to 24% over the following two hours. Only minor amounts of radioactivity were recovered in the neutral (sugar-containing) fraction over this same period. Alanine was transiently labelled early in the chase period, while glutamine accounted for 15% of the radioactivity recovered in the basic fraction after two hours. The evolution of (CO2)-C-14 from [C-14]aspartate and the accumulation of aspartate-derived C-14 in glutamine, glutamate and alanine were inhibited by the aminotransferase inhibitor aminooxyacetic acid. Seventy-one to 76% of the C-14 supplied to the pedicel as [C-14]aspartate appeared in the endosperm basic fraction, mainly as glutamine plus glutamate. Direct uptake of glutamine by the endosperm of kernels with pedicels removed was inhibited by 2,4-dinitrophenol and by p-chloromercuribenzenesulphonic acid, suggesting active transport of glutamine by the basal endosperm transfer cells. The role of pedicel amino acid metabolism in maize kernel nitrogen assimilation is discussed.

Soils were infested before each of the first four plantings with Rhizoctonia solani AG-8 or R. oryzae, or left non-infested. R. solani stunted seedlings during the first planting. After a second or third crop, depending upon the soil origin, shoot weights were significantly higher in infested soils than in controls. Shoot growth was never suppressed when soils were infested with R. oryzae. Disease suppressiveness tests performed during a fifth crop demonstrated that successive plantings of wheat into soils infested with R. solani AG-8 caused a decline of the disease. Both a susceptible host (wheat) and virulent pathogen (R. solani AG-8) were necessary to achieve disease suppressiveness. In contrast, R. oryzae did not induce soil suppressive to R. solani. Induction of Rhizoctonia root rot decline occurred earlier in tilled than nontilled soil, and rates of applied nitrogen had little effect on decline.

Franco] seedlings reduces water stress in the seedlings during drought periods. Seedlings were grown in pasteurized mineral soil under well-watered conditions and fertilized periodically with a small amount of nutrient solution containing P at either of three levels: 0, 20, or 50 mg P L-1. By age 6 mo, leaf nutrient analysis indicated that N and P were deficient in control (0 mg P L-1) seedlings. The highest level of P fertilization, which doubled leaf P concentration, did not affect plant biomass, suggesting that N deficiency was limiting growth. When these seedlings were subjected to drought, there was no effect of P fertilization on leaf water potential or osmotic potential. Furthermore, P fertilized seedlings had lower stomatal conductance and net photosynthesis rate. These results indicate that enhanced P nutrition, in the presence of N deficiency, does not reduce water stress in Douglas fir seedlings during drought periods.

As measured by the erosion-bridge method, most erosion occurred in a single, intense storm in December after the fire and amounted to an estimated 2 to 4 cm of surface soil. Captured eroded soil had a higher pH and P and Mg levels than residual soil. Seedlings of Libocedrus decurrens and Pseudotsuga menziesii were planted on eroded plots with additions of captured eroded soil (ET) or pasteurized eroded soil (PET) transferred to the planting holes. After one growing season, Libocedrus seedlings formed nearly 4 times the vesicular-arbuscular mycorrhizae in ET treatments and more than twice as much in PET treatments than in controls. Survival and basal area growth were significantly better in ET than in the other treatments, and both ET and PET produced more seedling shoot growth than did controls. Pseudotsuga seedlings did not differ in measured characteristics between treatments; ectomycorrhiza formation was slight, evidently the result of reduced inoculum potential resulting from the fire.

This research was initiated to evaluate wheat accessions for detection of resistance to the RWA. Over 12,000 wheat cultivars and plant introductions (PIs) from the USDA-ARS National Small Grains Collection were evaluated for reaction to RWA feeding damage. Twenty-nine PIs from Iran, Afghanistan, and the former Soviet Union, of various agronomic backgrounds were identified as having moderate to high levels of RWA resistance. This information is useful to wheat breeders searching for sources of resistance to the RWA to incorporate into their breeding programmes.

Comparisons were made between plants grown and measured at 350 and 700 muPa Pa-1 partial pressures of CO2 for amaranth, soybean and sunflower grown in controlled environment chambers, soybean grown outdoors in pots, and orchard grass grown in field plots. In amaranth, soybean and orchard grass, both the absolute and the relative sensitivity of conductance to DELTAw at the leaf surface were less in plants grown and measured at the elevated CO2. In sunflower, there was no change in the sensitivity of conductance to DELTAw for the two CO2 partial pressures. Tests in soybeans and amaranth showed that the change in sensitivity resulted from elevated CO2 during the measurement of the DELTAw response. Assimilation rate of CO2 was not altered by DELTAw in amaranth, which has C4 metabolism. In sunflower, the assimilation rate of plants grown and measured at elevated CO2 was insensitive to DELTAw, consistent with the response of assimilation rate to intercellular CO2 partial pressure in the prevailing range. In soybean, the sensitivity of assimilation rate to DELTAw was not different between CO2 treatments, in contrast to what would be expected from the response of assimilation rate to intercellular CO2 partial pressure.

All factors except pH affected the multiplication rate. Shoot multiplication was the best on a modified Driver and Kuniyuki medium for Paradox walnut (DKW) supplemented with 6-benzylaminopurine (BA) (1.5 - 3 mg/l). Plants grown on 3% glucose or fructose medium produced more and longer shoots than those on sucrose. The general appearance and growth habit of shoots were better on medium with glucose than fructose. 'Nonpareil' shoots elongated better than those of 'Tonda Gentile Romana.' Changes in medium pH from 4.7 to 5.7 did not significantly affect the multiplication rate. More than 10 genotypes propagated well on modified DKW medium with glucose. This is the first report of the effect of carbon sources on shoot multiplication of hazelnut and provides a basis for further research in the improvement of hazelnut micropropagation.

Kinetin (0.5 muM) and 10% (v/v) coconut water in callus initiation medium were inhibitory to subsequent embryogenesis. Embryogenic calluses on N6 medium increased in fresh weight with proline concentration up to 90 mM. Maximum fresh weight was achieved with 5% sucrose. Although genotypic differences were observed, embryogenesis occurred in all 17 sugarcane clones tested. Embryogenic calluses of one cultivar regenerated green plants after 16 months, but suspensions were totipotent for only 8 months. Total number of regenerated plants decreased with time in culture, while the number of pale green plants increased starting after 5 months in culture.

The trees were potted and randomly arranged under wire mesh platforms elevated 1.8 m from the ground. Diseased hazelnut branches were placed on top of the platforms in low, medium, or high numbers to provide three levels of inoculum. During periods of rain, ascospores of the pathogen were released from the diseased branches and deposited on the potted trees. External disease symptoms developed at 16 and 28 mo after initial exposure to inoculum, at which times disease responses were evaluated. Cultivars differed significantly in disease incidence, mortality, number of cankers per tree, proportion of wood cankered, and proportion of dead wood. The cultivars Hall's Giant, Willamette, Casina, and Tonda di Giffoni had the lowest disease severities. Barcelona, Ennis, Butler, Daviana, and DuChilly, the predominant cultivars in Oregon, were rated as moderately to highly susceptible. Gasaway, an obsolete pollenizer, did not develop disease symptoms. Inoculum density did not affect the relative resistance rankings of the cultivars. In a second experiment beginning in 1990, 44 hazelnut clones (cultivars and selections) were exposed to a high dose of A. anomala ascospores. Five clones-Gasaway, Gem, Winkler, Giresun 54-21, and Giresun 54-56-failed to develop symptoms of eastern filbert blight. An additional 13 clones were more resistant than the widely grown cultivar Barcelona. The relative resistance rankings of the cultivars evaluated in both experiments were consistent between experiments. C1 OREGON STATE UNIV,DEPT HORT,CORVALLIS,OR 97331.

In only a few cases, however, have the MLOs associated with the disease been characterized. We used biological and genetic data to establish that the causal agent of tomato big bud (TBB) disease in California is the beet leafhopper-transmitted virescence agent (BLTVA) MLO. Healthy Circulifer tenellus leafhoppers acquired the BLTVA MLO from field-collected, symptomatic tomato plants and transmitted it to healthy tomato plants, which developed typical big bud symptoms. Healthy tomatoes inoculated with the BLTVA type line (FC-83-13) also developed the floral gigantism and virescence characteristic of the disease. A California TBB MLO isolate caused symptoms typical of those caused by the BLTVA, including induction of premature flowering, on a standard plant host range. Southern blot analysis of DNA from field plants and from greenhouse tomato plants inoculated with a California TBB MLO isolate showed that all samples possessed plasmids that hybridized with a cloned BLTVA MLO plasmid. Macrosteles fascifrons did not transmit a virescence agent from symptomatic, field-collected tomatoes, and tomato plants infected with western aster yellows MLO failed to develop floral gigantism or virescence.

It was observed with supercoiled, linearized and single-stranded DNA structures that stimulation of transient gene expression in preheated protoplasts was neither dependent on the reporter gene nor on the regulatory elements used. Heat treatment at 42-degrees-C also increased expression in protoplasts transfected with a plasmid bearing the tobacco mosaic virus (TMV) translational enhancer, OMEGA. Northern blot analysis revealed that heat treatment of protoplasts before the transfection event greatly increased the amount of the newly synthesized transcripts. Preheating of protoplasts did not affect the transfection efficiency, namely the number of transfected cells in the population, nor the amount of DNA in transfected nuclei, as was inferred from histochemical staining and Southern blot analysis, respectively. The possible mechanism by which heat treatment stimulates transient gene expression of genes lacking obvious heat shock elements is offered. The relevance of the present findings to transient gene expression in plants in general and to viral gene expression in particular is discussed. C1 USDA ARS,CTR PLANT GENE EXPRESS,ALBANY,CA 94710.

Sequence analysis of the pMA1949 clone shows it to be a 991 bp partial cDNA encoding a polypeptide of 317 amino acids with homology to two group 3 LEA proteins, carrot (DC8) and a soybean protein encoded by pGmPM2 cDNA. Molecular analysis of the deduced protein reveals a 33 kDa acidic and extremely hydrophilic protein with potential amphiphilic alpha-helical regions. In addition, the protein contains eleven similar, contiguous repeats of 11 amino acids, which are separated by 118 amino acids from two additional and unique repeats of 36 residues each at the carboxyl end of the protein. Comparisons of sequences of reported group 3 LEA proteins revealed that there are two types, separable by sequence similarity of the 11 amino acid repeating motifs and by the presence or absence of a certain amino acid stretch at the carboxyl terminus. Based on results from these comparisons, we propose a second type of group 3 LEA proteins, called group 3 LEA (II). C1 WASHINGTON STATE UNIV,USDA ARS,PULLMAN,WA 99164.

AAT1 was detected only in extracts of cotyledons from dark-grown seedlings. AAT3 and AAT4 were detected in crude extracts of leaves and in cotyledons of seedlings grown in the light. AAT2 and AAT5 were detected in all tissues examined. A soybean leaf cDNA clone, pSAT17, was identified by hybridization to a carrot AAT cDNA clone at low stringency. pSAT17 had an open reading frame which could encode a 50581 Da protein. Alignment of the deduced amino acid sequence from the pSAT17 open reading frame with mature AAT protein sequences from rat disclosed a 60 amino acid N-terminal extension in the pSAT17 protein. This extension had characteristics of a plastid transit peptide. A plasmid, pEXAT17, was constructed which encoded the mature protein lacking the putative chloroplast transit polypeptide. Transformed Escherichia coli expressed a functional soybean AAT isozyme, which comigrated with the soybean AAT5 isozyme during agarose gel electrophoresis. Differential sucrose gradient sedimentation of soybean extracts indicated that AAT5 specifically cofractionated with chloroplasts. Antibodies raised against the pEXAT17-encoded AAT protein specifically reacted with the AAT5 isozyme of soybean and not with any of the other isozymes, indicating that the soybean cDNA clone, pSAT17, encodes the chloroplast isozyme, AAT5.

Previous evidence indicated MuA2 controls activity of the Mu1 transposon located in the mutable allele a1-mum2. MuA2 contains two large, ATG-initiated open reading frames (ORFs) of 612 and 232 codons, respectively, located on opposite strands. MuA2 produces two transcripts, each containing one of these ORFs. Four different tandem direct repeat sequences are located downstream of the 612 codon ORF. The restriction map of MuA2 is identical to that of transposon MuR1, which also is known to regulate mutability of a1-mum2. Furthermore, except for a single nucleotide, MuA2 is identical to the Mutator element Mu9. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT BIOCHEM & BIOPHYS,AMES,IA 50011.

The reciprocal F1 plants differed in C-13/C-12 ratios of leaves and the percentage of C-14 initially incorporated into C4 acids, being more like the pollen parents in these traits. They did not differ in apparent photosynthesis or in O2 inhibition of apparent photosynthesis and differed only slightly in CO2 compensation concentration at 175 mumol quanta m-2 s-1 and 400 mL L-1 O2. The C-13/C-12 ratios of 78 F2 progeny from the two F1 plants exhibited a normal distribution centered between those of the parents, with a few values slightly higher and lower than the parents. Apparent photosynthesis at 130 muL L-1 CO2 and inhibition of photosynthesis by O2 was nearly normally distributed in the F2 population, but no values for F2 plants approached those for F. brownii (15.4 mumol m-1 s-1 and 7.8%, respectively). Distribution of the CO2 compensation concentration measured at 1000 mumol quanta m-2 s-1 and 400 mL L-1 of O2 in the F2 population was skewed toward F. brownii with 72% of the progeny having values <9 muL of CO2 L-1 compared to 1.5 and 27.2 muL L-1 for F. brownii and F. linearis, respectively. Correlations among traits of F2 plants were low (coefficients of 0.30 to -0.49), indicating that the C4-related traits are not closely linked in segregating populations. Plants in the F2 population selected for high or low apparent photosynthesis at 130 muL of CO2 L-1 (six each) did not rank consistently high or low for C-13/C-12 ratios, O2 inhibition of apparent photosynthesis, CO2 compensation concentration, or activities of phosphoenolpyruvate carboxylase or NADP-malic enzyme. This study confirms results of earlier work that indicates independent segregation of C4 traits and also shows that the C4-like parental type can be recovered, at least for some characteristics (C-13/C-12 ratio), in segregating populations. Recovery of fully functional C4 plants awaits further experimentation with C4 x C3 or C4 x C3-C4 hybrid plants that produce fertile progeny. C1 USDA ARS,RICHARD B RUSSELL AGR RES CTR,ATHENS,GA 30613.

Semi-logarithmic plots of TTC reduction as a function of incubation time at different temperatures from 40 to 60-degrees-C resembled the heat survival curves of animal cells. Heal inactivation rates were obtained and subjected to ''quasi'' Arrhenius analyses by analytical methods derived from the animal studies. The Arrhenius plots of TTC reduction rates for cv Ashley leaf discs preincubated at 25 or 37-degrees-C and for cv Poinsett 76 preincubated at 37-degrees-C were linear with the same activation energy (E(a)) of about 80 kcal mol-1. The Arrhenius plot of cv Poinsett 76 preincubated at 25-degrees-C was nonlinear with an E(a) of about 80 kcal mol-1 at temperatures below 46-degrees-C and an E(a) of about 27.5 kcal mol-1 at temperatures above 47-degrees-C. The significance of these differences is discussed in terms of the role of protein denaturation in the thermal sensitivity of cucumber disc reduction of TTC and the applicability of these methods to the analysis of plant cellular heat sensitivity.

Exposure of microsomes and Rubisco to monochromatic 300-nm radiation resulted in the loss of intrinsic tryptophan fluorescence and the production of blue-emitting fluorophores. The major product of tryptophan photolysis was tentatively identified as N-formylkynurenine (N-FK). Even though the rates of tryptophan photodegradation and N-FK formation were similar the amount of blue fluorescence produced was significantly higher in the microsomes relative to Rubisco. Studies with various free radical scavengers and other modifiers indicated that tryptophan photodegradation requires oxygen and that the subsequent formation of N-FK may involve reactive oxygen species. The optimum wavelengths for loss of typtophan fluorescence were 290 nm for the microsomes and 280 nm for Rubisco. The temperature dependence of tryptophan fluorescence and rate of tryptophan photodegradation indicated an alteration in the cucumber microsomal membranes at about 24-degrees-C, which influenced protein structure and tryptophan photosensitivity.

They are bounded by a monolayer of phospholipids in which a few distinct proteins (oleosins) are embedded. Synthesis of soybean (Glycine max) 24-kD oleosin was analyzed by in vitro transcription and translation in reticulocyte lysate in the presence of canine microsomes. Our results show that 24-kD oleosin is cotranslationally integrated into microsomal membranes. We demonstrate that oleosin is integrated into a bilayer membrane in preference to the oil body monolayer membrane, indicating that oleosin is synthesized on the endoplasmic reticulum (ER). A new model of oil body assembly involving a conformational change through initial association with the ER membrane is proposed.

In contrast, leaf tissue of the tobacco cultivar Hicks was insensitive to EIX at concentrations 100-fold higher than was needed to elicit responses from Xanthi. Cell-suspension cultures of Xanthi and Hicks showed similar differences in sensitivity to EIX. Equivalent levels of ethylene production were elicited in leaf discs of both cultivars after treatment with CuSO4. The F1 and Xanthi backcross progeny of Hicks and Xanthi (crosses were all sensitive to EIX, whereas the F2 and Hicks backcross progeny segregated for sensitivity to EIX. Individual plants from the F2 and Hicks backcross that were insensitive to EIX produced only insensitive progeny when they were self-pollinated. Progeny from sensitive plants either segregated for sensitivity to EIX or produced all sensitive progeny (an F2 plant). Sensitivity to EIX is controlled by a single dominant gene, based on chi-square analysis of segregation ratios. C1 USDA ARS,BELTSVILLE AGR RES CTR,FRUIT LAB,BELTSVILLE,MD 20705.

Mutant embryo and endosperm ACCase activities were more than 600-fold less sensitive to sethoxydim inhibition than ACCase in wild-type kernel tissues. Moreover, in vitro cultured mutant kernels developed normally in the presence of sethoxydim concentrations that inhibited wild-type kernel development. The results indicate that the Acc1-encoded ACCase accounts for the majority of ACCase activity in developing maize kernels, suggesting that Acc1-encoded ACCase functions not only during membrane biogenesis in leaves but is also the predominant form of ACCase involved in storage lipid biosynthesis in maize embryos.

In Experiment 1, three dietary treatments were used: an unsupplemented practical corn-soybean meal basal diet; the basal diet supplemented with 2.64 mg folic acid/kg of diet; and the basal diet supplemented with 5.51 mg folic acid/kg of diet. Eggs from hens fed 2.64 mg folic acid/kg of diet were injected with folic acid in 20 injection trials over two production cycles. The response data from dietary supplemental folic acid were analyzed on a production period basis using all of the hens, and on a subset of hens producing eggs in each production period, for hatchability of fertile eggs and poult weight. The response patterns in each case were similar. Incremental dietary supplemental folic acid levels produced a positive linear response pattern on the transfer of folic acid in eggs, but did not result in a hatchability increase over the unsupplemented folic acid basal diet. Hatchability increase did not occur for eggs injected at 25 days of incubation with 19.3 mug folic acid per egg in 20 injection trials over two cycles of production. The results of the study indicate that hatchability is not increased in turkey eggs from hens fed supplemental folic acid or with egg folic acid injections. However, egg and poult weights were significantly increased (P <.05) in eggs containing 6 to 7 mg folic acid/g of dried egg, from hens fed 5.51 mg folic acid/kg of diet.

Broilers were stunned at either 50 or 200 V alternating current (VAC) for 10 s in a brine stunner. The artery and vein on one side of the neck were severed, blood collected for 90 s, and blood loss calculated as percentage of live weight. Carcasses were then processed under simulated commercial conditions. In the first experiment, the right and left Pectoralis major muscles were excised at 1 and 2 h post-mortem respectively, weighed, vacuum-sealed in plastic bags, and held overnight at 2 C. In the second experiment, the Pectoralis major muscles were excised at 4 h post-mortem and held overnight at 2 C. The muscles were then heated at 85 C for 30 min, equilibrated to room temperature, and prepared for Warner-Bratzler shear analysis. The stunning treatments did not significantly affect blood loss, which averaged 2.86 and 2.64% for 50 and 200 VAC, respectively. Birds subjected to the 50 VAC treatment had a mean shear value of 7.3 kg, which was significantly lower (P < .05) than the mean shear value of 10 kg for birds subjected to the 200 VAC treatment for muscles excised 2 h post-mortem. The use of 200 VAC for stunning could be used without any detrimental effect on the cooked meat as long as the standard deboning time of 4 h was maintained.

The current study was conducted to investigate the influence of phenotype (ob versus ln) and source of dietary carbohydrate (sucrose versus starch) on intestinal sucrase, maltase, lactase, and alkaline phosphatase activity in SHR/N-cp rats. For 3 months, lean and obese male SHR/N-cp rats were fed isocaloric diets containing as the sole source of carbohydrate either 54% cooked corn starch or sucrose. Serum and urine markers for diabetes were observed in obese rats. Wet weight and length of intestines were significantly increased in obese rats compared with lean littermates. Among the intestinal enzymes measured, statistical tests confirmed that sucrase activity was significantly increased (P < 0.01) by both phenotype (ob > ln) and feeding a sucrose diet. Diet alone (sucrose > starch) significantly increased (P < 0.05) maltase activity in obese rats, but had no effect on lean rats. Lactase activity was significantly higher (P < 0.05) in obese sucrose-fed rats compared with obese starch-fed and/or lean littermates. Statistical tests revealed that intestinal alkaline phosphatase activity was significantly altered (P < 0.05) by both phenotype and diet. Intestinal alkaline phosphatase was higher in starch-fed lean rats compared with lean littermates fed sucrose and to starch or sucrose-fed obese rats. These results are not indicative of a simple, nonspecific increase in intestinal enzyme activity, since the effects observed in intestinal alkaline phosphatase contrast the effects observed in intestinal sucrase, maltase, and lactase activity. These results indicate that both phenotype and diet alter structural and enzymatic intestinal activities of SHR/N-cp rats. Distinct variations in the observed intestinal enzymatic activities suggest that these enzymes are under the control of genetic, hormonal, and dietary factors. Rationale for these differences are discussed. C1 GEORGE WASHINGTON UNIV,MED CTR,WASHINGTON,DC 20052.

Previous investigations showed that F. moniliforme cultured on corn and incorporated into rat chow increased brain 5-hydroxyindoleacetic acid (5HIAA) and 5HIAA: serotonin (5HT) ratios in these animals. Therefore, this study was undertaken to determine whether fumonisin B1 would produce related neurochemical effects in the brain and pineal gland of male and female rats. Rats were fed fumonisin B1 at 15, 50, and 150 ppm for 4 weeks. No differences occurred in brain concentrations of norepinephrine, dopamine, 3,4-dihydroxyphenylacetic acid, 3-methoxytyramine, homovanillic acid, 5HT, 5HIAA, and the 5HIAA to 5HT ratios in either male or female rats, nor where there differences between the sexes. When compared across sexes, the norepinephrine to dopamine ratios were decreased (P < 0.05) in the 150-ppm-treated animals. This may suggest a fumonisin B1-induced imbalance in brain norepinephrine and/or dopamine. No differences were observed in pineal norepinephrine, 5HT, 5HIAA, and the 5HIAA to 5HT ratios. Since fumonisin B1 failed to duplicate the effects of the F. moniliforme-induced imbalances in 5HT and 5HIAA metabolism in the brains of rats, other mycotoxins from F. moniliforme may be responsible for these effects.

Supplementation with (n-3) PUFA decreases lymphocyte proliferation in human and animal models. The present study was designed to compare the effect of (n-3)- and (n-6)-derived eicosanoids on mitogenic response. Mouse splenocytes and human peripheral blood mononuclear cells (PBMC) were cultured in the presence or absence of the T cell mitogen Conconavalin A (CON A) with and without the addition of PGE2, LTB4, PGE3 and LTB5 at several concentrations. Lymphocyte proliferation was determined by measuring incorporation of [H-3]thymidine into newly synthesized DNA. Both (n-3) and (n-6)-derived eicosanoids inhibited T cell mitogen-induced lymphocyte proliferation in human PBMC and murine splenocytes. The addition of PGE3 and LTB5 decreased Con A-induced mitogenic response in human PBMC more than the same concentration of PGE2 and LTB4 (e.g. -28.7+/-4.2% with 10(-9) M PGE3 VS -9.4+/-6.3% with 10(-9) M PGE2, P=0.05 and -95.5+/-1.6% with 10(-11) M LTB5 vs -49.2+/-3.8% with 10(-11) M LTB4, P<0.001). A similar trend was observed in murine splenocytes. It is concluded that PGE3 and LTB5 are as potent and at some doses more potent than PGE2 and LTB4 in inhibiting lymphocyte proliferation when added in vitro. These data suggest that eicosanoids derived from (n-3) PUFA may contribute to the (n-3) PUFA-induced suppression of lymphocyte proliferation.

A titration to establish the minimum immunising dose was performed in American mixed breed goats by vaccinating test subjects with dilutions of Vero cell-adapted rinderpest vaccine and then challenging 26 days later with virulent peste des petits ruminants virus. All animals were followed for virus neutralising antibodies against both rinderpest and peste des petits ruminants virus after vaccination and challenge. The antibody response to vaccination was primarily against rinderpest virus with very low levels of cross-reactivity to peste des petits ruminants virus. Following challenge, animals which possessed anti-rinderpest neutralising antibodies remained clinically normal but mounted strong anti-peste des petits ruminants virus neutralising antibody responses indicating that replication of challenge virus took place without the induction of illness. The 50 per cent minimum goat immunising dose was 3 tissue culture infectious doses 50 per cent (TCID50) as established by serological response and protection against challenge. The thermostable Vero cell-adapted rinderpest vaccine is a suitable immunogen for the protection of goats against peste des petits ruminants.

Carrier erythrocytes prepared from white-tailed deer (Odocoileus virginianus) do not circulate well in vivo. Although carrier cells were prepared from sickle and non-sickle cells with no apparent differences, their 24-hour survival was only 10 per cent. Osmotic fragility of carrier cells was increased over that of normal deer erythrocytes. Unlike erythrocytes from other ruminants, deer carrier erythrocytes are extremely fragile. Scanning electron micrographs of deer erythrocytes (sickle or non-sickle) in different stages of carrier cell preparation revealed no morphological differences. These data suggest that carrier cells from deer would not be amenable for use in long-term dissemination of drugs. C1 TEXAS A&M UNIV SYST,DEPT PATHOBIOL,COLL STN,TX 77843.

In vivo resistance was determined by field inoculation with one isolate. There was no correlation between any in vitro measurement and in vivo resistance, and none of the in vitro measurements on control mediums were correlated. The only significant correlation for the same measurement between the two isolates was for pollen-tube length (r=0.65). Percent of pollen germination was negatively correlated with callus growth for both isolates. Earlier work showed that callus growth in the presence of culture filtrate was linked to plant resistance, thus it appeared that percent pollen germination on culture filtrate had decreased for the more resistant plants. The haploid pollen may be used as a progeny test for identifying heterotic loci conferring resistance to Fusarium, but if the pollen of this plant species is used in direct selection by exposure to culture filtrate, the level of resistance to Fusarium may decrease.

Control lambs were fed a 40% concentrate diet (40C) at 1.5 X NE(m) requirement during period 1 (64 d). Another group (1X/2X) was fed 40C at 1 and 2 X NE(m) in 4-d intervals during period 1; a third group (70/10) was fed 70% and 10% concentrate diets in 4-d intervals during period 1. To achieve dry matter intake comparable to controls, 70/10 lambs were fed at 1. 79 (70C) and 1.21 (10C) x NE(m). All lambs were placed on the control diet during period 2 (32 d) and increased to 2X maintenance during period 3 (32 d). During period 2, ADG and gain/feed of control lambs tended to be greater (P<0.10) than for lambs fed alternating treatments. Liver weight as a percentage of hot carcass weight was greater (P<0.05) for controls than for lambs fed alternating treatments. Hot carcass weight (P=0.07) and dressing percentage (P=0.09) tended to be greater for the 70/10 treatment than for controls. The 1X/2X treatment lowered (P<0.05) serum cholesterol compared with other groups on d 65, but not on d 0 or 129. Smaller liver weight per unit of hot carcass weight for lambs in the 1X/2X and 70/10 treatments suggests a possible reduction of maintenance requirements.

Selectivity coefficients used to describe this distribution typically vary from soil to soil. In certain instances, however, there is evidence that this variability may be accounted for on the basis of exchange selectivities of predominant mineral exchangers. This study was undertaken to determine whether cation transport in soils in which either hydroxy-interlayered smectite or interstratified smectite-vermiculite is the predominant exchanger could be adequately described using exchange data for montmorillonite. Experimental data for binary (Ca-Mg) or ternary (Ca-Mg-Na) miscible displacement through columns of Olivier series (fine-silty, mixed, thermic Aquic Fragiudalf) or Yolo series (fine-silty, mixed, nonacid, thermic Typic Xerorthent) soils were adequately described when cation-exchange selectivities for montmorillonite were used.

Statistical methods commonly applied in the estimation of the median of lognormally distributed data, however, are biased or inefficient. The purpose of this study was to evaluate four statistical methods for estimating, from sample data, the median of a lognormal population. The four statistical methods were: (i) the geometric mean (GM), (ii) a bias-corrected form of the geometric mean (BCGM), (iii) a uniformly minimum variance unbiased (UMVU) estimator, and (iv) the sample median (SM). In addition, two techniques for computing confidence limits about the median were evaluated. Monte Carlo simulations from four different lognormal populations were used in these evaluations to determine the efficacy of these methods as a function of both population variance and sample size (n = 4-100). Results of this work indicate that the UMVU estimator and the BCGM estimators are unbiased and yield estimates with the lowest mean square error. An example is provided that illustrates the application of these techniques. C1 UPJOHN CO,KALAMAZOO,MI 49001.

The modified method was tested for speed, ease of use, susceptibility to error, NH4+ recovery, and precision. Modifications included (i) use of a 60-cm3 polypropylene syringe as the incubation vessel rather than a glass test tube, and (ii) KCl extraction of sample NH4+ within the syringe and colorimetric determination of N rather than sample transfer to an extraction flask and subsequent N analysis. The syringe modification reduced sample setup and extraction time by one-third while significantly increasing analysis precision. Net NH4+ production in the syringe compared favorably with that in the standard test tube when a 1-h shake extraction was employed. The potential for error due to NO3- reduction to NH4+ via a dissimilatory NO3- reduction pathway was quantified with N-15. Of the 21 mg N kg-1 of N-15-labeled KNO3 added prior to incubation, 14% was reduced to NH4+, corresponding to a 5% error in the measurement of mineralizable N.

Presently all dense layers found in the region arc considered unaltered dense basal tills. Comparisons between morphological and physical properties of five pedons in Massachusetts previously classified as having fragipans and typical fragipan properties were undertaken to ascertain the possible existence of fragipans. Morphologically, the pans contained the typical fragipan features outlined in the soil taxonomy including bleached prism faces (BPF), lack of rooting in the pan, and the presence of an eluvial horizon just above the pan. Physically, the pans have a high bulk density and sometimes enough increase in clay content to meet the taxonomic criteria for an argillic horizon. Additionally, the pans show redoximorphic features and indications of lateral water movement across their upper surface. The argument that the pans that developed in dense basal till in Massachusetts are largely geogenic in origin does not appear valid. C1 UNIV MASSACHUSETTS,DEPT PLANT & SOIL SCI,AMHERST,MA 01003.

Thin-section observations indicated that Btx horizons contain common void argillans and clay bridges. This contrasts with the Cd horizons, which contain few and mostly poorly developed argillans. Skeleton grains in the bleached Btx horizon prism faces are relatively clean and occur in a silty matrix. Ferrans and ferriargillans occur along the prism boundaries within the fragipan matrix. Mangans and ferrans are the most typical features in the Cd horizons, coating the surfaces of the plates that are characteristic of these horizons. The fabric of Btx horizons is predominantly skelsepic, while that of Cd horizons is dominantly insepic to asepic. BCd horizons are similar to Btx horizons but with less well developed argillans and lacking bleached prism faces. The transition from the well-developed Btx horizon fabric to the poorly developed agrillans and plasma separations of the underlying parent materials (Cd horizons) indicates pedogenic development within the fragipans.

Nonvolcanic materials, however, predominate in southeast Alaska, yet andic properties are common in Spodosols throughout the area. A well-drained, forested Spodosol was sampled in Holocene beach deposits with no more than traces of volcanic glass. The pedon has a thin E horizon and a spodic horizon that has andic soil properties typical of Spodosols in southeast Alaska. Acid-oxalate-extractable Al + (Fe/2) is 3.6% in the Bh, 5.8% in the Bhs, and 6.4% in the Bs horizon. Soil bulk densities are low and P retention is >90% in all subhorizons of the spodic horizon. The soil is an Andic Humicryod. About one-third of the Spodosols in nonvolcanic materials of southeast Alaska meet the andic or aquandic subgroup requirements of Haplocryods, Humicryods, or Cryaquods. In addition, other Spodosols have andic properties in subhorizons of a spodic horizon < 25 cm thick and some are in lithic subgroups. Rapid weathering and leaching, high organic matter content, and cool temperatures promote the accumulation of amorphous Al and Fe compounds in the perudic soils of southeast Alaska.

The objectives of this study were to investigate water infiltration into a cracked clay soil during flood irrigation, and to observe the differences in infiltration and cracking patterns between fallow soil following wheat (Triticum turgidum L. 'Yecoro Rojo') and soil under alfalfa (Medicago sativa L. 'CUF 101'). A large weighing lysimeter was used to measure infiltration and evaporation. The infiltration was analyzed as consisting of three phases of crack filling, sorption, and transmission. The infiltration curves were found to be similar for all irrigations, with a larger percentage of the total infiltrated water initially entering the cracks of the drier alfalfa soil (74%) than the wheat-cropped soil (63%). Final infiltration rates were 0.4 and 0.6 mm h-1 for the alfalfa and wheat irrigations, respectively. Evaporation was shown to be a large component of water loss during the later stages of irrigation, sometimes exceeding the infiltration rate. Cracking patterns could be observed because of the presence of foam, which consists of organic acids picked up by water rising in the cracks. The wheat-cropped fallow soil had more numerous cracks than alfalfa-cropped soil, which was attributed to its fiberous root system, which is weaker than the alfalfa taproot system. The difference in cracking patterns between the two crops has implications for water flow. C1 USDA ARS,SALIN LAB,RIVERSIDE,CA 92501.

Tillage treatments included: moldboard plowing (MP), chisel plowing (CP), and no-till (NT). No-till treatments had significantly (P = 0.05) more organic C accompanied by a similar increase of cation-exchange capacity (CEC) in the 0- to 15-cm layer in both sites than other tillage methods. High bulk density and penetration resistance were measured in the traffic zone (TZ) compared with the row zone (RZ) in the top 15 cm under NT treatments. The mean hydraulic conductivity in NT plots was 12 times more than CP and MP for TZ and 15 times more for RZ. The aggregation percentage and mean weight diameter (MWD) were significantly (P = 0.05) more in NT compared with other treatments in both zones and sites. The available water-holding capacity (AWC) was in the order of NT > CP > MP, with significant differences among treatments. The mean AWC in NT plots was 24% more than CP and 23% more than MP for RZ, and 8% more than CP and 11% more than MP for TZ. C1 OHIO STATE UNIV,DEPT AGRON,COLUMBUS,OH 43210.

This study was conducted to develop and verify a simple procedure to predict soil aggregate and crust density from soil physical properties. A predictive equation based on saturated water content and clay content of seven soils was developed. Soil textures ranged from fine sandy loam to clay with organic matter contents of 4.7 to 64.6 g kg-1. Bulk densities of aggregates and crusts of 10 soils were predicted using the procedure developed in this study and were measured by the clod method. Soil aggregate and crust textures ranged from loamy fine sand to clay with organic matter content of 4.7 to 47.4 g kg-1. Predicted and measured aggregate densities had similar values. However, the predicted crust densities were lower than those measured. Results of this study indicate that the procedure developed in this study can be used as a relatively simple, fast, and reliable technique to predict aggregate densities in similar soils.

Fabrics finished with citric acid by efficient catalysis have good appearance properties that are durable to multiple launderings. Advantages of citric acid over other polycarboxylic acids are low cost, ready availability and proven lack of toxicity. With proper choice of catalyst, a yellowing problem associated with citric acid finishing is reduced.

The instrument (AFIS) includes a mechanism for mechanically opening a hand-fed ribbon of fibers so that individual fibers can be presented aerodynamically to an electro-optical system for measuring fiber length. Length measurements for 10,000 individual fibers can be obtained in approximately 5 minutes. Although there are measurements for the entire fiber length distribution, measurements of mean length, upper half mean length, and short fiber content are particularly important. Measurements of mean length and upper half mean length can be made rapidly with other instruments, but instruments to rapidly measure short fiber content have not been available until now. Evaluation results show good correlations between measurements made using conventional laboratory methods and measurements using AFIS. C1 ZELLWEGER USTER INC,KNOXVILLE,TN 37919.

Alternatively, and competitively, photoperiod gene activity causes the photosynthate to be partitioned predominantly toward continued growth of new vegetative organs plus later initiation of more reproductive (yield) organs. This hypothesis was tested by comparing an insensitive and a photoperiod-sensitive bean (Phaseolus vulgaris L.) cultivar and their F1 with F2 segregates of undetermined genotype. Randomly derived homozygous F8 segregates were also compared. The F8 generation included one photoperiod-insensitive and one photoperiod-sensitive genotype in a 1:1 ratio, which verified control by one photoperiod gene. Under long daylength (LD), in addition to early versus late flowering and maturity, the two genotypes expressed opposite levels of 23 other traits that would be changed by competitive partitioning of the photosynthate. In contrast, under short daylength (SD), both genotypes flowered and matured early, and both expressed the levels for all 25 traits that the photoperiod-insensitive genotype expressed in both SD and LD. The photoperiod gene interacted with daylength to control the levels of all three major physiological components of yield: the aerial biomass, harvest index, and days to maturity. Included among the other traits with levels altered by daylength-modulated photoperiod gene activity were: the number of branches, nodes, leaves and leaf area, the rate of yield accumulation, and sink activity.

In these plus many other cited crops, photoperiod sensitive gene(s) delay days to flowering and/or days to maturity in non-promotive daylength while simultaneously lowering the harvest index. Thus, for many crops, earlier maturity is associated with higher harvest index, and/or it has been shown that photoperiod gene(s) control partitioning of photosynthate toward reproductive growth versus toward competitive partitioning to continued vegetative growth. Our conclusion is that photoperiod gene control over this partitioning precedes and is causal of the photoperiod-gene control over days to flowering and maturity. This implies shifts from commonly accepted paradigms about effects by photoperiod and about breeding for higher yield. These paradigm shifts suggest more efficient ways to breed for cultivar adaption to the specific growing season duration and environment of each geographical site and for higher crop yield.

(2) a superior rate of actual yield accumulation in order to acquire a high harvest index, and (3) a time to harvest maturity that is neither shorter nor longer than the duration of the growing season. That duration is provided by the environment, which is the fourth major determinant of yield. Simultaneous selection is required because genetically established interconnections among the three major physiological components cause: (a) a correlation between the harvest index and days to maturity that is usually negative; (b) a correlation between the harvest index and total biomass that is often negative, and (c) a correlation between biomass and days to maturity that is usually positive. All three physiological components and the correlations among them can be quantified by yield system analysis (YSA) of yield trials. An additive main effects and multiplicative interaction (AMMI) statistical analysis can separate and quantify the genotype x environment interaction (G x E) effect on yield and on each physiological component that is caused by each genotype and by the different environment of each yield trial. The use of yield trials to select parents which have the highest rates of accumulation of both biomass and yield, in addition to selecting for the G x E that is specifically adapted to the site can accelerate advance toward the highest potential yield at each geographical site. Higher yield for many sites will raise average regional yield. Higher yield for multiple regions and continents will raise average yield on a world-wide basis. Genetic and physiological bases for lack of indirect selection for biomass from exclusive selection for yield are explained. C1 FAC SCI AGRON ETAT GEMBLOUX,UER PHYTOTECH REG CHAUDES,GEMBLOUX,BELGIUM.

Previous studies have indicated that the source of cytoplasmic male sterility discovered in 1925 by Jones (S-cytoplasm) may be an alien cytoplasm. Restriction enzyme analysis of the chloroplast DNA (cpDNA) revealed five polymorphisms between S and normal (N) fertile cytoplasms. S-cytoplasm was different from the Allium species closely related to the bulb onion, and cladistic estimates of phylogenies supported introduction from an unknown species. S-cytoplasm was identical for all polymorphisms in the cpDNA to 'Pran', a triploid viviparous onion. 'Pran' shares morphological characteristics with 'Italian Red 13-53', the single plant source of S-cytoplasm. Densiometric scans of autoradiograms revealed that 12 of 31 open-pollinated populations of onion possessed S-cytoplasm and that introgression may have occurred since the discovery of S-cytoplasm.

(2n = 6x = 42) and the availability of aneuploid lines was exploited in designing a strategy for mapping beta-tubulin sequences in the oat genome. Evidence for a minimum of eight beta-tubulin genes was obtained by Southern-blot analysis. Three beta-tubulin sequences were localized to chromosomes using DNA from monosomic and nullisomic lines in the variety Sun II. One sequence was localized to the chromosome missing in nullisome I. Two other sequences were mapped to satellite chromosome 2, the chromosome that is missing in nullisome VIII and to which one ribosomal RNA gene cluster had previously been mapped. Restriction fragments carrying these two beta-tubulin genomic sequences and the cluster of ribosomal RNA sequences were missing in DNA from nullisomics VIII, IX and X, suggesting that all three nullisome classes are deficient for an identical chromosomal segment that includes these three loci. This study demonstrates how molecular analyses can be used to characterize aneuploid stocks and to better define their genetic constitution. C1 UNIV MINNESOTA,DEPT GENET & CELL BIOL,ST PAUL,MN 55108.

Our hypothesis was that LPS-induced abortion was primarily a maternal luteolytic event with minimal transplacental fetal exposure. Fetal tibial arteries, amniotic, allantoic cavities and maternal carotid arteries were catheterized. Three cows had patent catheters with viable fetuses (190 to 200 days of gestation) 1 week after operation and were included in the study. Following a 2-day maternal and fetal baseline, 0.5 mug Salmonella typhimurium LPS/kg was infused into a maternal jugular vein over a 2-hour period. maternal and fetal responses were monitored clinically, biochemically and hormonally. The maternal response consisted of marked increases in plasma prostaglandin F2alpha metabolite (PGFM), tumor necrosis factor (TNF), ACTH and cortisol with a dramatic maternal leucopenia within 2 hours. Progesterone concentrations decreased within 7 hours (P<0.05). The LPS was rapidly cleared from maternal circulation and no transplacental exposure was detected in the fetuses. Fetal responses to maternal endotoxemia consisted of increased ACTH and cortisol concentrations with delayed increases in PGE2; TNF did not change in fetal fluids following maternal endotoxemia. There was a fetal leucocytosis within 2 hours. The results indicate that the fetus does not appear to play a major role in the pathogenesis of LPS-induced abortions. However, the role of maternal TNF in endotoxin abortion requires further study. C1 USDA,BELTSVILLE,MD 20705. UNIV UTAH,SALT LAKE CITY,UT 84112. CORNELL UNIV,DEPT PATHOL,ITHACA,NY 14853.

Fumonisins are hydroxylated long-chain alkylamines esterified with propanetricarboxylic acid moieties that represent approximately half the mol. wt of the toxins. The A-series fumonisins are N-acetylated, whereas the B series contains free amino groups. Hydrolytic removal of the propanetricarboxylic acid moieties from fumonisins B1 an B2 yields the corresponding aminopentols, AP1 and AP2, respectively. These compounds were tested for toxicity on widely differing bioassay systems, representing plant and animal systems. The plant bioassay system employed jimsonweed (Datura stramonium L.) leaves and leaf discs in which toxicity was detected as electrolyte leakage, photobleaching and quantitation of chlorophyll reduction. The animal bioassay system employed cultured mammalian cell lines in which toxicity was detected as inhibition of cell proliferation. Fumonisins B1, B2 and B3 at 50 mug/ml or less were effective toxins after exposure periods greater than 24 hr in all plant and animal bioassay systems examined, except 3T3 mouse fibroblasts, whereas fumonisins A1 and A2 exhibited little or no activity. However, the hydrolytic degradation products AP1 and AP2 exhibited toxicity similar to or greater than B-series fumonisins in all test systems, including substantial toxicity to 3T3 mouse fibroblasts.

The current study tested the Goryachkin crushing and lifting theories' prediction of soil flow across a sweep by comparing with measurements from observed soil flow. Treatments included sweeps with three different rake angles (13.5, 16, and 44-degrees) operated at three speeds (5, 7, and 9 km/h) and at two depths (50 and 100 mm). Flow direction was determined from scratch marks on the sweep surface. In agreement with the Goryachkin theories, observed soil flow changed with rake angle, but not with speed or depth. In a manner opposite of that predicted by the theories, the ratio of vertical to lateral soil movement increased as rake angle increased. Most predicted values were outside of a 99% confidence interval of observed means. Soil flows on the sweep did not deviate appreciably (more than 5-degrees) from a vertical plane parallel to the travel direction. The theories did not adequately predict observed soil flow on a sweep. C1 USDA ARS,NATL SOIL TILTH LAB,AMES,IA 50010.

Soil shift, or lateral soil movement, and ridge height were affected by both tool operating speed and sweep rake angle. Faster speeds and steeper rake angles created larger ridges. Change in surface height, an indicator of soil loosening, was significantly affected by tool depth and speed, but not by sweep rake angle. Deeper operation created a higher soil surface. The lateral movement of soil into the ridge was more closely related to vertical movement of soil on the tool than to lateral soil movement on the tool. C1 USDA ARS,NATL SOIL TILTH LAB,AMES,IA 50010.

The radar output was corrected for pitch angle of the radar antenna based on the output of an antenna-mounted tilt sensor. The effects of ground cover, aircraft speed and height, and transducer mountings on error in the speed and height signals were investigated. The error in the pitch-corrected radar output was not significantly affected by any of the test variables. Error tended to increase with pitch angle and speed. Ground speed error was within 4.7% of the true value. The pitch-corrected radar output is valid only for changes in aircraft pitch unaccompanied by vertical velocities. The performance of the ultrasonic height transducer was most affected by ground cover. Height errors increased from 6.5% to 21.0% over a concrete runway as ground speed and flying height increased. Transducer output over grass was inconsistent and errors varied from 8.1% to 58.3%. Operation of the height transducer was affected by airflow around the transducer chassis and aircraft-generated noise.

Macroporosity of the soil was assumed to be 0.05% by volume, half of which was continuous and the rest discontinuous. Two rainfall sequences with two initial soil water contents, evaporation versus transpiration, macropore radius ranging from 1.0 to 0.125 mm, and three different chemicals were evaluated Over a five-week period, weekly rainfall of 25.4 mm in one hour, with soil water redistribution and evaporation or transpiration occurring between storms, generated no macropore flow when the soil was initially dry (-1500 kPa). A slight amount of macropore flow was generated under the same rainfall when the soil was initially wet (-33 kPa). Doubling the weekly rainfall amount and intensity generated macropore flow varying between 30 to 50% of rainfall depending on initial and boundary conditions. Chemicals transported with this flow were 0.05 to 8% of the surface-applied amount, depending on conditions and type of chemical. A moderately adsorbed chemical (Atrazine) was the most susceptible to macropore transport, followed in order by a strongly adsorbed chemical (Prometryn), and a mobile chemical (Nitrate). The flow entering the macropores was partially absorbed by soil at progressively deeper depths; it. increased the water content of the root zone, and created a tail of low concentrations in the soil chemical content distributions. The macropore size had very little effect on macropore flow and transport, but the smallest size pores retarded the downward chemical movement by wall adsorption a little more than the largest size pores. Surface evaporation decreased macropore flow, soil water contents, and downward chemical movement, but increased chemical content of the macropore flow. Transpiration, on the other hand, decreased both macropore flow and its chemical content. Thus, this modeling study gives very useful insights into the macropore flow behavior that are very difficult to obtain experimentally, and which will be useful in characterizing macropore flow in the field.

The model was based upon a fluctuating watertable equation derived by de Zeeuw and Hellinga of The Netherlands. This equation only requires two parameters to describe daily watertable fluctuation: (1) a reaction factor for a receding or rising watertable, and (2) a recharge coefficient to account for the portion of rainfall which causes the watertable to rise. For a given water management system, these parameters can be estimated from observed (measured) watertable responses for a representative number of rainfall events. The model was calibrated and tested to evaluate its application in simulation of a subsurface drainage system. Climatological and watertable data from a field drainage experiment at the Louisiana Agricultural Experiment Station's Ben Hur Research Farm, Baton Rouge, Louisiana, was used to calibrate the model. Monthly averages of the daily reaction factor of watertable fluctuations and the daily recharge coefficient of soil moisture were determined from three years of data from the field experiment. Recharge coefficients were multiplied by a correction factor to account for antecedent soil moisture conditions prior to the onset of rainfall events. The reciprocal of moisture deficit in the soil profile was used to estimate the correction factor. The standard deviation of differences between the observed and FWTMOD simulated daily watertables was 23.1 cm for a seven-year evaluation period, 1981 to 1987. For comparison purposes, the more complex and comprehensive drainage simulation model DRAINMOD was also used, with a resulting 20.8 cm standard deviation of differences between the observed and predicted daily watertables. In general, the simpler model FWTMOD predicted daily watertable fluctuations nearly as well as DRAINMOD for conventional subsurface drainage in a Commerce silt loam soil. C1 USDA ARS,BATON ROUGE,LA.

This heavy duty unit evolved from a standard clothes dryer that was altered to simulate potato-on-potato tumbling in a rubber-lined rotating drum. Weight loss, sprouting, cellular leakage, and respiratory changes of three stored cultivars were periodically monitored following different amounts of simulated handling. Simulated handling stress, detected in all of the tuber assays, was largely monotonically related to the number of revolutions received in the drum of the simulator. The unit developed in this study has served as a reliable, durable handling simulator that, when coupled with the appropriate size and quantity of tubers in a sample, can simulate potato-on-potato tumbling with repeatable results.

The complex impedance of bulk samples at 1 and 10 MHz was used along with a density-independent function to predict moistures ranging from approximately 11 to 22% in samples with bulk densities ranging from 0.65 to 0.85 g/cm3. Calibration was performed on wheat of two cultivars harvested in 1991, and verification was tested on a different cultivar harvested in 1990. Measurements of the system were compared to air-oven moisture determinations with a standard deviation of the differences of 0.5% moisture content.

Aeration in one bin was controlled by a programmable microprocessor and in the second bin, it was controlled manually with temperature limit settings. In each bin, 132 thermocouples were installed to measure the temperatures of grain at different depths and different radial distances from the bin center. Temperatures of the bin wall, bin floor, and air above the grain surface were also measured Temperatures were recorded daily using a programmable data acquisition system. Each bin was filled with 99.3 t of Hard Red Winter Wheat to a depth of 3.66 m. Tests were started in May 1988 and ended in December 1990. A model was developed to predict the temperature of grain during storage. The model was based on a two-dimensional transient heat conduction equation with the associated boundary conditions and was solved using the finite difference method for a cylindrical geometry. The model included several sub-models which predicted temperature profiles of soil under the bins, solar radiation on bin wall at any time of day, and convective heat transfer coefficient for the bin wall. Local hourly weather data (air temperature, relative humidity, wind speed, and solar radiation on horizontal surface) and airflow rates during aeration periods were used as model inputs to simulate the temperatures of grain during storage. Predicted and measured grain temperatures were in close agreement for a test period of 32 months. Results indicated that the model and the parameter values used in the model are applicable for predicting temperature Of stored wheat with and without aeration.

A 2D2D, 1D3D, and a large diameter (LD) cyclone were used in the experiment. The efficiencies of the 2D2D and the 1D3D cyclones were similar when used as primary collectors. In the first year both the LD+1D3D and 2D2D+1D3D arrangements of cyclones were equally effective in reducing total and PM 10 particulate emissions. However, in the second year the 2D2D+1D3D cyclone combination reduced total emissions by 28.9% and PM 10 emissions by 31.5% over the LD+1D3D combination. The 2D2D+1D3D combination had the highest pressure drop of all the treatments, but a better reduction of particulate emissions. Therefore, the 2D2D+1D3D system was the most efficient configuration of those tested. RP COLUMBUS, EP (reprint author), USDA ARS,US COTTON GINNING LAB,STONEVILLE,MS 38776, USA.

Although data on fruit yields in response to salinity are limited, they indicate that grapefruit, lemons, and oranges are among the most sensitive of all agricultural crops. Fruit yields decrease about 13% for each 1.0 dS m-1 increase in electrical conductivity of the saturated-soil extract (EC(e)) once soil salinity exceeds a threshold EC, of 1.4 dS m-1. Accumulation of excess Cl- and Na+ can cause specific ion toxicities, but this problem can be minimized by selecting rootstocks that restrict the uptake of these ions. During the past two decades, numerous papers describing the agronomic and physiological responses of citrus to salinity have been published. This paper reviews these research reports and discusses differences in the response of citrus species to salt stress, the rote of different rootstocks, the causes of salt injury, and the interactions of other environmental conditions or stresses with salinity.

The measure is based on the theory of the household production of recreation supply. It measures the availability of a set of recreation resources to households in a given location as an input to producing recreation trips, relative to the availability of the same set of resources to households in other locations. The measure described is developed as an index, to allow for combining several different types of recreation resources into a more comprehensive metric of availability of a particular recreation environment. Recreation supply availability is shown to be positively related to the amount of resources, and negatively related to both competing populations and the distance separating households and resources. The steps taken to calculate 1989 RPA recreation opportunity indices are described and illustrated with a hypothetical example.

Little work has been reported on the effect of BIV infection on bovine immune function. This study was designed to evaluate lymphocyte blastogenesis, mononuclear cell subset numbers, neutrophil function, hematology, and clinical signs in three groups of cattle. These groups were evaluated at 0-2 months post inoculation (PI, Group 1), 4-5 months PI (Group 2), or 19-27 months PI (Group 3). BIV infected animals were inoculated with the R-29 isolate of BIV in tissue culture cells, peripheral blood mononuclear cells from a R-29 infected calf, or a molecular clone of the R-29 isolate. Most inoculated animals seroconverted to BIV by Western immunoblot. BIV was reisolated from most of the animals inoculated. BIV infection was associated with an increase in the lymphocyte blastogenic response to the mitogen phytohemagglutinin in Groups 2 and 3. Neutrophil antibody dependent cell mediated cytotoxicity and neutrophil iodination were decreased (P<0.05) in BIV infected cattle (Groups 2 and 3 and Group 3, respectively). All animals were clinically normal during the evaluation periods. Notable differences were not observed in the other assessments performed. Work with additional BIV isolates and over longer time frames is warranted. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT MICROBIOL IMMUNOL & PREVENT MED,2178 VET MED,AMES,IA 50011.

Because sampler data cannot be collected at the same time and place as ''true'' trap measurements, the ''probability-matching method'' was used to derive surrogate pairs for calibration analysis. The method is invalid since it implicitly assumes that sampler and trap data have no sampling or measurement errors, it gives biased and highly variable results, and it does not contain information enabling model specification. A new calibration model was developed that regresses transformed individual sampler measurements on daily means of transformed trap data and incorporates within-day variation in trap rates to explain part of the sampler variation. Three small-nozzle samplers performed more uniformly than three large-nozzle samplers did. There is evidence that samplers with higher nozzle ratios collect more bed load in most particle size classes tested. However, between the two small-nozzle samplers with ratios of 3.22 and 1.40, significant differences could be detected for only one particle size. The standard sampler with a 76 x 76 mm nozzle trapped sediment less efficiently than a similar sampler with a 152 x 152 mm nozzle in three of four particle sizes tested. Limitations in the data restricted more definitive statements about the samplers, but the results of this study can be used to design a more rigorous calibration experiment.

The immunizing antigen was derived from decayed southern yellow pine wood blocks extracted in phosphate-buffered saline and Triton X-100, and fractionated by column chromatography. Five IgG monoclonal antibodies were selected for characterization by enzyme-linked immunosorbent assay (ELISA) and western blot. Each mAb exhibited binding to two major protein bands on western blot at 32 kDa and 36 kDa. Characterization by chemical and enzymatic modification of the antigen determined whether mAbs were protein specific or specific for the carbohydrate portion of the glycoprotein. Affinity chromatography with the protein specific mAbs demonstrated specific binding to beta-1,4-xylanase and cross-reactivity with beta-1,3-glucanase, beta-1,4-glucanase, and beta-1,4-mannanase. These mAbs were also immunoreactive with polysaccharidases from liquid culture filtrates when tested by ELISA. The mAbs have been utilized to successfully detected P. placenta by ELISA in decayed southern yellow pine at a weight loss of 3.6%.

The year was 1920 and the compound was phenylurethane (ethyl N-phenylcarbamate or EPC). Warburg found that it strongly inhibited photosynthesis in Chlorella. EPC did not develop into a commercial herbicide, but the isopropyl derivatives (propham and chlorpropham) which were introduced in the late 1940s became selective herbicides. The phenylureas (monuron and diuron) were introduced in the early 1950s and shortly thereafter, interference with the Hill reaction by both phenylureas and phenylcarbamates was reported. During the latter part of the 1950s, into the 1960s, and even now, additional herbicidal chemistry was and is being announced that interferes with the Hill reaction. Duysens, in 1963, identified the site of action of diuron, i.e., on the acceptor side of PS II. Corwin Hansch, in 1966 introduced the SAR or QSAR concept in which inhibitory action of Hill inhibitors was related to various chemical and physical parameters. Because of differential responses to partial, thylakoid-associated reactions, the Hill inhibitors were subsequently divided into two groups: pure electron transport inhibitors (phenylureas, s-triazines, triazinones, and uracils) and inhibitory uncouplers (acylanilides, dinitrophenols, benzimidazoles, dinitroanilines, and benzonitriles). The inhibitory uncouplers (dinoseb-types), unlike the diuron-types, uncoupled photophosphorylation by interacting with the coupling factor complexes in both chloroplasts and intact mitochondria. Additionally, the bipyridyliums were shown to be reduced by PS I, hence, diverted electrons from the native acceptor. Field observations of triazine resistance were reported in 1970 and resistance was subsequently demonstrated at the thylakoid level. Application of the techniques of genetic engineering and biotechnology resulted in identification of the 32 kDa herbicide-binding protein and determination of its amino acid sequence. Crystallization and X-ray examination of the photosynthetic reaction center from Rhodopseudomonas by Michel et al. in the mid-1980s provided new models to account for interactions of herbicides with the D-1 protein. During the 1980s, herbicides were identified that interfered with biochemical machinery in chloroplasts that is not involved in electron transport and light harvesting: inhibition of lipid biosynthesis by aryloxyphenoxypropionates and cyclohexanediones, aromatic amino acid biosynthesis by glyphosate, branched chain amino acid biosynthesis by sulfonylureas and imidazolinones, carotenoid biosynthesis by pyridazinones, and porphyrin biosynthesis by diphenyl-ethers and oxadiazoles. The current status of research in most, if not all, of the above areas was reported through oral and poster presentations at this Omiya Symposium.

The gross symptomology for all of these porphyrinogenic herbicides is similar. Porphyrin accumulation induced by three porphyrinogenic herbicides acifluorfen (AF), delta-aminolevulinic acid (ALA), and 2,2'-dipyridyl (DY) was determined by in vivo spectrophotometry and HPLC methods. The averaged in vivo difference spectra between untreated and AF-treated (30 muM for 20 h in darkness) yellow cucumber cotyledon discs approximated the absorption spectra of protoporphyrin IX (Proto IX). There was also an enhanced peak near 503 nm. Treatment of cotyledon discs with ALA alone generated a difference spectrum of protochlorophyllide (PChlide) in combination with Mg-Proto IX or Mg-Proto IX monomethyl ester (Mg-Proto IX ME). With ALA and AF in combination, the PChlide and Mg-Proto IX portions of the difference spectrum were reduced and the Proto IX peak and peak near 503 nm were increased. DY treatment yielded a difference spectrum with peaks approximating those of Proto IX and Mg-Proto IX ME, along with a peak near 503 nm. The presence of all porphyrins detected by in vivo spectrophotometry except for the 503 nm peak was confirmed with HPLC. Proto IX monomethyl ester was found by HPLC to be especially elevated in treatments with AF. The in vivo 503 nm peak and in vitro studies with Protox-containing barley etioplast preparations suggest that prototetrahydroporphyrin IX (an oxidation state intermediate between protoporphyrinogen IX and Proto IX) may accumulate under some conditions. These data demonstrate that rapid in vivo spectrophotometric studies can provide much of the qualitative results of HPLC studies and can confirm that in vitro results correspond with the in vivo situation.

One of these, PR-toxin, is produced by Penicillium roqueforti. We report here the isolation of a gene (Ari1) coding for the sesquiterpene cyclase, aristolochene synthase (AS), from P. roqueforti. Nucleotide sequence analysis of genomic and cDNA clones revealed that the Ari1 gene contains two introns. A Protein A/AS fusion enzyme was expressed in Escherichia coli and shown to have sesquiterpene cyclase activity. Analysis of the Protein A/AS fusion enzyme reaction mixtures by TLC and gas chromatography/mass spectrometry identified aristolochene as a major product. The Ari1 gene encodes a polypeptide of molecular weight 39,200. Expression of Ari1 occurs in stationary phase cultures of P. roqueforti and appears to be transcriptionally regulated.

In electrophoretic mobility shift assays, non-methylated duplex DNAs competed only slightly, while methylated DNAs were strong competitors. Specific binding still occurred after partial proteolysis of DBPm, but not after heating at 45-degrees-C. By ultraviolet light-crosslinking and sodium dodecyl sulfate polyacrylamide gel electrophoresis and gel filtration, the size of pea seed DBPm was estimated to be in the range 70-90 kDa. From equilibrium binding studies the equilibrium constant for binding of pea seed DBPm to a 34 bp duplex deoxyoligonucleotide containing 12 5-methylcytosine residues was 1.2 . 10(9) M-1. The binding properties of DBPm make it a good candidate for a plant protein capable of mediating the effects of DNA methylation on the activity of some plant genes.

We developed procedures that permit the obtaining of data that properly characterize and quantify the DMA behavior of these aqueous systems. Particularly important factors are substrate selection, sample clamping geometry, and sample humidification prior to analysis. In this report, we illustrate the problems encountered and the steps that we adopted to resolve them. We also present preliminary DMA data that illustrate some approaches for measuring the degree of cure achieved during previous resin exposures. One especially promising approach employs the area under the tan delta curve during isothermal scanning as an inverse measure of precure. C1 UNIV WISCONSIN,DEPT CHEM ENGN,MADISON,WI 53706.
