Environmental and human impacts on off-target movement of dicamba
(University of Missouri--Columbia, 2020)
and soybean injury were adequate and accurate to predict soybean yield reductions in response to dicamba. Lastly, a subset of soybeans exposed to dicamba concentrations (0, 150, and 300 ppm dicamba) were collected prior to harvest, extracted using the rapid...
Quorum sensing in soft-rotting Erwinia carotovora
(University of Missouri--Columbia, 2005)
) and protease (Prt) that are known or predicted to function as virulence and pathogenicity factors. The production of these exoproteins is activated by quorum sensing (QS)signal, N-acyl homoserine lactone (AHL). At elevated temperatures, however, a majority of E...
Soybean emergence, growth, and development following corn stover removal
(University of Missouri--Columbia, 2012)
available and easily obtainable. Understanding how corn stover removal affects soybean emergence and development is essential to developing appropriate management recommendations for both partners in a corn-soybean rotation. The objectives of this study were...
Herbage accumulation, nutritive value and nitrogen dynamics of a tall fescue forage system with either nitrogen fertilization or intercropped sunn hemp
(University of Missouri--Columbia, 2019)
of this project were to alternative solutions to increase tall fescue forage system productivity and nitrogen dynamics during the summer and fall of a tall fescue system when sunn hemp is intercropped. Results from our first experiment suggested that nitrogen...
Development and validation of a DNA microarray for analysis of the Bradyrhizobium japonicum transcriptome
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bradyrhizobium japonicum, forms a nitrogen fixing symbiosis with soybean. The ability to survive in soil environments, colonize the rhizosphere and establish effective plant...
Response of beef cattle selected for tolerance to tall fescue toxicosis
(University of Missouri--Columbia, 2019)
Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) infected with the endophytic fungus, Epichlooجا coenophiala [(Morgan-Jones & W. Gams) C.W. Bacon & Schardl, comb. nov.] produces ergot alkaloids that result in a livestock disorder known...
Dissipation and carryover of imidazolinone herbicides in imidazolinone-resistant rice (Oryza sativa)
(University of Missouri--Columbia, 2007)
herbicide carryover. Studies were conducted on two soils commonly utilized for rice production: a DeWitt silt loam and a Sharkey clay soil. Treatments included several variations including common programs with imazamox added, double-rate treatments...
Utilizing radiotracer and genetic approaches to determine the regulation of sucrose export in maize leaves
(University of Missouri--Columbia, 2018)
2 describes my work on developing a new tool using radioactive Fluorine-18 ([18]F) labeled sucrose to visualize sugar transport in maize plants. Physiological, genetic, and biochemical evidence showed that maize SUCROSE TRANSPORTER1 (ZmSUT1...
Remobilization of leaf nitrogen in stockpiled tall fescue
(University of Missouri--Columbia, 2010)
that autumn senescing leaves remobilized 45-60% of leaf N by spring. Through mid-winter, remobilized leaf N supported areas of active growth, including new tillers, crowns, new rhizomes, and a proliferation of new roots. In crowns and new roots, free amino...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of the effect of alternate...
Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
to evaluate the performance of publicly-available N fertilizer recommendation tools across a wide range of soil and weather environments for 1) prescribing EONR for planting and split N fertilizer applications, 2) improve understanding of the economic...
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
of semiaquatic Heteroptera were collected in this study. This includes an undescribed genus, 50 undescribed species, and 7 new country records. A biogeographic study based on presence/absence data was conducted using Cluster analysis, TWINSPAN, and DECORANA...
