Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that fit well into mixed row crop/livestock operations as they can be used both as a cover crop and as a source of winter pasture. ...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
Subterranean termite species in the genus Reticulitermes are ecologically and economically important in the United States. At least six species of the genus Reticulitermes are native from North American forests where they ...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified ...
Detection of phythium spp. in gold course irrigation systems
(University of Missouri--Columbia, 2020)
Many Pythium spp. are causal agents of disease on creeping bentgrass putting greens. Phytopathogenic Pythium spp. are known to disseminate through irrigation systems in agricultural settings, and this study provides evidence ...
Coordinating the overall stomatal response of plants : rapid leaf-to-leaf communication during light stress
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants, being sessile organisms, have evolved unique mechanisms enabling them to rapidly react to ever-changing environmental conditions. In nature, ...
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. ...
Chloroplast GFP expression in tobacco plants agroinfiltrated with tobacco mosaic virus based vectors
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Viruses are submicroscopic infectious particles comprising of nucleic acid and protein which can replicate only within living host cells. TMV is a ...
Sulfur metabolism in Glycine max [L.] Merr : characterization of serine acetyletransferase and O-acetylserine (thiol) lyase
(University of Missouri--Columbia, 2006)
Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...
Comparison of three tall fescue-based stocker systems
(University of Missouri--Columbia, 2009)
A two-year study was conducted on tall fescue-based pastures to evaluate three approaches to rotationally stocking stocker calves. Within each year, two sets (a spring set and a fall set) of crossbred steers were stratified ...
Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
Plants store inorganic phosphate (Pi) in seeds as phytic acid (PA). Phytic acid chelates essential macro and micronutrients in developing seeds forming phytate, which is nutritionally unavailable to monogastric livestock. ...
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)
Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ...
Buriscon regulated immune response in Drosophila melanogaster
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bursicon is a heterodimeric neurohormone which binds to the receptor LGR2 and regulates various aspects in cuticle sclerotization and wing expansion ...
Extracellular ATP, apyrase and nodulation of non-legumes
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] ATP is a universal energy source for biochemical reactions in all living organisms. Extracellular ATP (eATP) is well studied in animal processes such ...
Utilizing radiotracer and genetic approaches to determine the regulation of sucrose export in maize leaves
(University of Missouri--Columbia, 2018)
for constructing a fully automatic controlled growth chamber that can be easily adapted in plant biology laboratories as well as classrooms. The system can be used to study plant responses to numerous abiotic and biotic stress conditions and to grow...
Associations between Wolbachia, maize and Diabrotica virgifera virgifera
(University of Missouri--Columbia, 2008)
Diabrotica virgifera virgifera which is infected with Wolbachia, is the most significant and widespread pest to maize in North America and Europe. Wolbachia are obligate intracellular bacteria which seem to be limited to ...
