Cross-Polarized Magic-Angle Spinning 13c Nuclear Magnetic Resonance Spectroscopic Characterization Of Soil Organic Matter Relative To Culturable Bacterial Species Composition And Sustained Biological Control Of Pythium Root Rot, Michael J. Boehm, Tianyun Wu, Alex G. Stone, Bart Kraakman, Donna A. Iannotti, G. Edwin Wilson, Laurence V. Madden, Harry A.J. Hoitink

Department of Plant Pathology: Faculty Publications

We report the use of a model system that examines the dynamics of biological energy availability in organic matter in a sphagnum peat potting mix critical to sustenance of microorganism-mediated biological control of pythium root rot, a soilborne plant disease caused by Pythium ultimum. The concentration of readily degradable carbohydrate in the peat, mostly present as cellulose, was characterized by cross-polarized magic-angle spinning 13C nuclear magnetic resonance spectroscopy. A decrease in the carbohydrate concentration in the mix was observed during the initial 10 weeks after potting as the rate of hydrolysis of fluorescein diacetate declined below a critical threshold level …

Effect Of Sediment Particle Size And Temperature On Fecal Bacteria Mortality Rates And The Fecal Coliform/Fecal Streptococci Ratio, J. M. Howell, Mark S. Coyne, P. L. Cornelius

Plant and Soil Sciences Faculty Publications

Extended survival of fecal bacteria in sediment can obscure the source and extent of fecal contamination in agricultural settings. The variability in fecal coliform/fecal streptococci (FC/FS) ratios with time and discrepancies between observable fecal sources and measured FC/FS ratios in shallow surface water from agricultural watersheds may be explained by examining FC and FS mortality rates in response to ambient temperature and sediment particle size. We measured FC and FS mortality rates at three different temperatures and in three feces-amended sediments with different particle size in a laboratory study. In controlled conditions, using physiological saline to reduce cell death by …

Transmittance And Reflectance Measurements Of Corn Leaves From Plants With Different Nitrogen And Water Supply, James S. Schepers, T. M. Blackmer, Wallace Wilhelm, M. Resende

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Nitrogen is essential for crop production, but also contributes to eutrophication of surface water and degradation of drinking water quality. Modern corn production requires relatively large quantities of N, which are generally supplied by fertilizers. Over-application of N fertilizers and animal wastes frequently results in nitrate leaching. Synchronizing N availability with crop N need offers the potential to protect the environment without sacrificing production. Tools are needed to rapidly and easily monitor crop N status to make timely decisions regarding fertilizer application. Analytical and optical techniques were evaluated with greenhouse grown corn at silking to evaluate several methods to monitor …

Defining Arealistic Control For The Chloroform Fumigation-Incubation Method Using Microscopiccounting And 14c-Substrates, William R. Horwath, Eldor A. Paul, David Harris, Jeanette M. Norton, Leslie Jagger, Kenneth A. Horton

Plants, Soils, and Climate Faculty Publications

Chloroform fumigation-incubation (CFI) has made possible the extensive characterization of soil microbial biomass carbon (C) (MBC). Defining the non-microbial C mineralized in soils following fumigation remains the major limitation of CFI. The mineralization of non-microbial C during CFI was examined by adding ¹⁴C-maize to soil before incubation. The decomposition of the ¹⁴C-maize during a 10-d incubation after fumigation was 22.5% that in non-fumigated control soils. Re-inoculation of the fumigated soil raised ¹⁴C-maize decomposition to 77% that of the unfumigated control. A method was developed which varies the proportion of mineralized C from the unfumigated soil …

Promoters From Chlorellavirus Genes Providing Expression Of Genes In Prokaryotic And Eukaryotic Hosts, Amitava Mitra, James L. Van Etten

Department of Plant Pathology: Faculty Publications

The invention is directed to novel promoters or mutants thereof from Chlorella virus DNA methyltransferase genes. A Chlorella virus gene promoter is operably linked to a first and/or second DNA sequence encoding a gene that is different from the Chlorella virus gene to form an expression cassette. An expression cassette can be introduced into prokaryotic and/or eukaryotic cells and can provide for a high level of expression of the gene encoded by the first and/or second DNA sequence. The invention also provides a method for screening other Chlorella virus genes for promoters that can function to express a heterologous gene …

Expression And Characterization Of An Rna Capping Enzyme Encoded By Chlorella Virus Pbcv-1, C. Kiong Ho, James L. Van Etten, Stewart Shuman

Department of Plant Pathology: Faculty Publications

We report that the A103R protein of Chlorella virus PBCV-1 is an mRNA capping enzyme that catalyzes the transfer of GMP from GTP to the 5’ diphosphate end of RNA. This is a two-step reaction in which the enzyme first condenses with GTP to form a covalent enzyme-GMP intermediate and then transfers the GMP to an RNA acceptor to form a GpppN cap. Purified recombinant A103R is a 38-kDa monomer that lacks RNA (guanine-7-) methyltransferase activity. With respect to its size, amino acid sequence, and biochemical properties, A103R is more closely related to the yeast RNA guanylyltransferases than it is …

A Cytoplasmic Male Sterility-Associated Mitochondrial Protein Causes Pollen Disruption In Transgenic Tobacco, Shichuan He, Andre R. Abad, Stanton B. Gelvin, Sally Ann Mackenzie

Center for Plant Science Innovation: Faculty and Staff Publications

In higher plants, dominant mitochondrial mutations are associated with pollen sterility. This phenomenon is known as cytoplasmic male sterility (CMS). It is thought that the disruption in pollen development is a consequence of mitochondrial dysfunction. To provide definitive evidence that expression of an abnormal mitochondrial gene can interrupt pollen development, a CMS-associated mitochondrial DNA sequence from common bean, orf239, was introduced into the tobacco nuclear genome. Several transformants containing the orf239M gene constructs, with or without a mitochondrial targeting sequence, exhibited a semisterile or male-sterile phenotype. Expression of the gene fusions in transformed anthers was confirmed using RNA gel …

Fire Management Of Spinifex Pastures In The Coastal And West Pilbara, John Stretch

Agriculture reports

Spinifex dominated plant communities are a major natural pasture resource in the Pilbara. Spinifex is noted for its ridged, hard and generally sharp pointed leaf blades, although individual species vary in this respect. Triodia pungens and T. schinzii are often referred to as soft spinifex. Soft spinifex is useful as stock feed in its own right, whereas 'hard' spinifex species are rarely grazed by stock. Soft spinifex dominated pastures are relatively uncommon in eastern parts but important on the western coastal plains of the Pilbara (Figure 1). Information on spinifex management options available to the pastoralist or station manager is …

Mechanical Conditioning For Controlling Excessive Elongation In Tomato Transplants: Sensitivity To Dose, Frequency, And Timing Of Brushing, Lauren C. Garner, Thomas Björkman

Horticulture and Crop Science

During production of plug transplants, the high plant density results in rapid stem elongation as plants compete for light. The resulting tall, weak-stemmed plants are difficult to transplant and are easily damaged. One technique that can prevent excessive elongation is mechanical stimulation by brushing. Wide adoption of brushing is limited by a lack of information on how plants respond to variations in applying the technique. Our investigation examined how tomato (Lycopersicon esculentum cv. Oh8245) seedling growth responded to varying doses of mechanical stimulation, varying intervals between brush strokes during stimulation, time of day that stimulation was applied, and growth stage …

Monoclonal Antibodies For Detection Of The H7 Antigen Of Escherichia Coli, Yongsheng He, James E. Keen, Ralph B. Westerman, E. Travis Littledike, Jimmy Kwang

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Two murine monoclonal antibodies (MAbs) (2B7 and 46E9-9) reactive with the H7 flagellar antigen of Escherichia coli were produced and characterized. A total of 217 E. coli strains (48 O157:H7, 4 O157:NM, 23 O157:non-H7, 22 H7:non-O157, and 120 non-O157:non-H7), 17 Salmonella serovars, and 29 other gramnegative bacteria were used to evaluate the reactivities of the two MAbs by indirect enzyme-linked immunosorbent assay (ELISA). Both MAbs reacted strongly with all E. coli strains possessing the H7 antigen and with H23- and H24-positive E. coli strains. Indirect ELISA MAb specificity was confirmed by inhibition ELISA and by Western blotting (immunoblotting), using partially …

Forage Quality Of "Matua" Prairie Grass, Kelly King

Masters Theses & Specialist Projects

Research on the nutritive quality of Matua grass (Bromus willdenowii) is limited in south central Kentucky-Due to the hot summers, mild winters and a 200-day long growing season in Kentucky, herbage quality as well as management practices may differ from those reported in research from other climates. The objective of this study was to evaluate the nutritive quality of five forages (Matua, Gala, Smooth bromegrass, Tall fescue and Orchardgrass). The experiment was conducted on a Pembroke silt loam (fine-silty, mixed, mesic mollic Paleudalfs) in south central Kentucky as well as in the greenhouse. Four harvests each were obtained from the …

Spikelet And Floret Naming Scheme For Grasses With A Spike Inflorescence, Wallace Wilhelm, Gregory S. Mcmaster

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Effective schemes to name uniquely and define parts of grass plants allow researchers to communicate results of their experiments accurately and precisely. Naming schemes for vegetative parts of grass plants have been developed; however, no system exists to name uniquely parts of the inflorescence. In this report, we present a method to extend existing systems to name parts of grass spikes. Spikelet positions are denoted by the letter S and numbered acropetally along the rachis. For example, the third spikelet position from the base of the rachis is named S3. Likewise, floret positions along the rachilla are named F (or …
