Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
Disease vector population densities, combined with their relationship to landscape characters, will clearly affect the proliferation of arboviruses to humans present in these landscapes. Advanced mapping techniques (e.g., ...
Reducing ergovaline and ergot alkaloid concentrations through fertilizer, herbicide and clipping management
(University of Missouri--Columbia, 2010)
Animals grazing tall fescue grass (Lolium arundinaceum) infected with Neotyphodium coenophialum consume the toxins ergovaline and other ergot alkaloids. This research included a series of experiments with two overall ...
The role of ERF transcription factors in defenses against specialist and generalist herbivores in Arabidopsis thaliana
(University of Missouri--Columbia, 2010)
Plant responses to herbivory are complex, involving differential perception, multiple signaling pathways, and the transcription of defense-responsive genes. Using a whole-genome microarray and bioinformatics tools, we ...
Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
Allelopathy is a complex phenomenon among plants that involves the production of defensive chemicals that influence the growth and survival of adjacent plants. Plants like perennial ryegrass become suspect when bermudagrass ...
Management practice effects on corn grain ethanol yield and ethanol byproduct quality
(University of Missouri--Columbia, 2010)
The Renewable Fuel Standard (RFS2) under the Energy Independence and Security Act of 2007 (EISA) currently requires the production and use of 136.08 billion liters of renewable fuels by the year 2022. A significant portion ...
Remobilization of leaf nitrogen in stockpiled tall fescue
(University of Missouri--Columbia, 2010)
Missouri's beef industry is supported by more than five million hectares of pasture containing the grass tall fescue (Lolium arundinaceum). Stockpiled (accumulated autumn growth used for winter grazing) tall fescue leaf ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
Annual bluegrass is the most problematic weed on golf courses in the Transition Zone and Southern United States. Applications of glyphosate are common on dormant zoysiagrass to remove winter annual weeds. In 2007, a suspect ...
Synthesis and evaluation of sigma receptor ligands
(University of Missouri--Columbia, 2010)
Sigma receptors are unique binding sites located in the central nervous system (CNS) and peripheral organs. Two sigma receptor subtypes ([signma]1 and [sigma]2) have been described so far. It is known that the [sigma]1 ...
Nutrient, water, and soil type mangement of biofuel feedstock production by corn, sorghum, and switchgrass
(University of Missouri--Columbia, 2010)
Efficient use of biomass to produce biofuel and the development of more drought tolerant crops can contribute to helping address current and future problems faced by mankind, and are the focus of this dissertation. Objectives ...
Pathway approaches to dissecting the inheritance of maize shoot-borne roots
(University of Missouri--Columbia, 2010)
Shoot-borne roots are essential plant components. Two pathway-based approaches were pursued to increase our understanding of genetic mechanisms controlling shoot-borne root patterning. The first pathway approach characterized ...
Physiological responses of continental (summer-active) and mediterranean (summer-dormant) tall Fescue to cold stress and identification of underlying QTL for fall growth and winter survival
(University of Missouri--Columbia, 2010)
We describe three experiments; the first two experiments were conducted in a greenhouse and with the use of cold chambers. The first experiment determined the effect of endophyte (Neotyphodium ceonophialum) presence under ...
Proteomic identification of the differentially expressed and phosphorylated proteins in 20-hydroxyecdysone (20E) signal transduction pathway in salivary gland of Drosophila melanogaster
(University of Missouri--Columbia, 2010)
Protein kinase C (PKC) plays important role in 20-hydroxyecdysone (20E) signal transduction, however, little is known about the exact role of PKC in this process. In my research, PKC-regulated phosphorylation in 20E signal ...
Evaluating the insect fauna on Missouri native wildflowers and selected cultivars
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Insects respond to a wide variety of plant characteristics in their search for plant provided resources. There is debate as to whether native cultivated ...
Comparative analysis of aquatic insect, amphipod, and isopod community composition along environmental gradients in rheocrene spring systems of Missouri
(University of Missouri--Columbia, 2010)
Spring systems in Missouri harbor a unique biota and provide critical initial discharge from subterranean aquifers to streams. However, little research has been conducted on the crenobiology or ecology in these systems. ...
The effects of drought stress and western corn rootworm feeding on maize root biology
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Drought and western corn rootworm (WCR), Diabrotica virgifera virgifera, can have substantial impacts on the potential yield of maize, Zea may L. Maize ...
