Exploring the symbiotic relationship of plants and microbes by mass spectrometry imaging
(University of Missouri--Columbia, 2019)
Current practices in agriculture make use of chemical inputs including nitrogen fertilizers to provide high crop yields since nitrogen is often the limiting nutrient in field soil. However, nitrogen fertilizer use has ...
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 underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity ...
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 ...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...
Characterizing hormesis and the in vitro effects of sub-lethal fungicide exposure in sclerotinia homoeocarpa
(University of Missouri--Columbia, 2018)
Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is the most economically important disease of turfgrass. Dollar spot reduces aesthetics and playability of turfgrass, and when left uncontrolled can result in ...
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 ...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
Poison hemlock is a biennial, toxic and invasive weed that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed ...
Factors that influence the movement of Cauliflower mosaic virus in susceptible and resistant plants
(University of Missouri--Columbia, 2018)
(severe), W260 (mild) and H12 (symptomless). I found that turnip aphids preferred W260-infected plants more than NY8153-, H12-infected or healthy plants. I concluded that aphids can recognize different strains of CaMV and will choose plants with specific...
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, ...
Iron homeostasis is hierarchically regulated by multiple inputs : evidence for the role of reactive oxygen species and iron-zinc cross talk
(University of Missouri--Columbia, 2018)
Iron (Fe) is a heavy metal micronutrient vital for all forms of life. In plants, Fe deficiency results in chlorosis and reduced growth, while Fe excess results in lipid peroxidation through the generation of reactive oxygen ...
Herbicide resistant weeds in Missouri : sources and solutions
(University of Missouri--Columbia, 2019)
that represented twice the recommended field use rate of glyphosate, glufosinate, 2,4-D, dicamba, and cloransulam was applied to each population in order to determine the frequency and distribution of herbicide resistances in Missouri horseweed. A population...
Characterization of berry and wine aroma development in interspecific hybrids important to Missouri using a metabolomics based approach
(University of Missouri--Columbia, 2020)
investigated the impact of rootstocks and irrigation treatments in berry and wine quality using an experimental vineyard planted with Chambourcin own-rooted as well as grafted to three commercial rootstocks (1103P, 3309C, SO4) subjected to three irrigation...
Sour rot : effects of fruit fly life stages, chemical management, and winemaking
(University of Missouri--Columbia, 2020)
-inoculated with causal organisms Metschnikowia pulcherrima and Gluconobacter cerinus, then exposed to either axenic D. melanogaster eggs, 24hr-old larvae, or adult life stages. Symptoms were rated daily based on severity scale of 0-4. After recording disease progression...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated...
Impact of aphids species and barley yellow dwarf virus on soft red winter wheat
(University of Missouri--Columbia, 2005)
Barley yellow dwarf virus is one of the most widespread viral diseases of wheat. Yield reductions up to 70% have resulted from barley yellow dwarf virus (BYDV) infection. Several aphid spp. transmit BYDV. In Missouri, the ...
