The bacterial type III-secreted protein AvrRps4 is a bipartite effector
(University of Missouri--Columbia, 2017)Like humans, plants have an immune system to protect themselves against invading pathogens. Unlike humans, however, the plant immune system is inborn and genetically predetermined by resistance genes. Pathogenic bacteria ... -
Comparative analysis of the role of cytokinin in feeding site formation induced by cyst and root-knot nematodes
(University of Missouri--Columbia, 2017)Cyst and root-knot nematodes are obligate plant parasites of global economic importance with a remarkable ability to reprogram root cells into unique feeding sites. Previous studies have suggested a role for cytokinin in ... -
Delayed maize lateral root determinacy induced by mild water deficit
(University of Missouri--Columbia, 2017)The capability of roots to mine the soil for available water is essential for survival and productivity, especially under water-limited conditions. The formation and elongation of lateral roots is an important process ... -
Elucidating the role of jasmonate metabolites in jasmonic acid signaling
(University of Missouri--Columbia, 2017)The plant hormone jasmonic acid controls immune responses against insect herbivory and regulates plant development. Jasmonic acid is synthesized upon wounding and herbivory and is converted to many derivatives collectively ... -
Evaluation of teosinte genetic diversity for agronomic and domestication traits in maize /
(University of Missouri--Columbia, 2017)The main objectives of my Ph.D. dissertation were to investigate the several aspect of genetic diversity in maize (Zea mays ssp. mays) and its wild relative, Teosinte (Zea mays ssp. parviglumis). In my dissertation research, ... -
Genetic and molecular analysis of soybean cyst nematode virulence
(University of Missouri--Columbia, 2017)The soybean cyst nematode (SCN) Heterodera glycines is the most economically important pathogen of soybean, capable of causing large scale yield loss on a global scale. Current management practices utilize host resistance, ... -
High density mapping and quantitative trait loci analysis for fungal diseases in vitis aestivalis-derived 'Norton' and breeding for low palmitic acid in glycine max
(University of Missouri--Columbia, 2017)Vitis aestivalis-derived 'Norton', the official grape of the State of Missouri, is grown in many U.S. regions where V. vinifera production requires extensive pesticide use for fungal disease management. To identify genetic ... -
Managing fescue toxicosis through forage canopy, limestone application, and novel endophytes
(University of Missouri--Columbia, 2017)Tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] infected with the endophytic fungus Epichlo coenophiala [(Morgan-Jones and W. Gams) C.W. Bacon and Schardl, comb. nov.] produces ergovaline and other alkaloids responsible ... -
Soil wetting agents influences on soil hydrophobicity : the effects and mechanisms
(University of Missouri--Columbia, 2017)Soil water repellency (SWR), which causes uneven water distribution in top soil, is a common problem for sandy soils, especially on sand-based growing media such as USGA (United States Golf Association) greens. The SWR is ...
