All Roads Lead To Weediness: Stories About Weedy Rice Origins, Weedy Genes And Weed Competitiveness, Zhongyun Huang Nov 2017

All Roads Lead To Weediness: Stories About Weedy Rice Origins, Weedy Genes And Weed Competitiveness, Zhongyun Huang

Doctoral Dissertations

Weedy rice (Oryza spp.), a weedy relative of cultivated rice (O.sativa), infests and persists in cultivated rice fields worldwide. Many weedy rice populations have evolved similar adaptive traits, considered part of the ‘agricultural weed syndrome’, making this an ideal model to study the genetic basis of parallel evolution. Using population genetics analyses of South Asian and US weedy rice, my research reveals multiple independent evolution events giving rise to weed groups in the two geographic areas. Weeds in South Asia have highly heterogenous genetic backgrounds, with contributions from both cultivated varieties (aus and indica) …

Gatekeepers Of Nitrogen-Fixing Symbiosis: Cytokinin-Ethylene Crosstalk Regulates Symbiotic Interaction In Lotus Japonicus, Seyedehmandana Miri Apr 2017

Gatekeepers Of Nitrogen-Fixing Symbiosis: Cytokinin-Ethylene Crosstalk Regulates Symbiotic Interaction In Lotus Japonicus, Seyedehmandana Miri

Electronic Thesis and Dissertation Repository

Leguminous plants thrive under nitrogen-limited soil conditions because of their ability to symbiotically interact with nitrogen-fixing bacteria, known as rhizobia. In the presence of compatible strains of rhizobia, they develop specialized symbiotic organs, called root nodules, which host the bacteria and provide the appropriate conditions for symbiotic nitrogen fixation to occur. The plant hormone cytokinin is the key endogenous trigger for the inception of root nodule organogenesis. In the model legume Lotus japonicus, analysis of the cytokinin receptor gene Lotus histidine kinase 1 (Lhk1) showed that it is required and also sufficient for the initiation of nodule …


A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood Jan 2017

A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood

Murray State Theses and Dissertations

One-third of our worldwide fruit, nut and vegetable production is completely dependent on the existence of pollinators. Commercial honey bees, Apis mellifera, have an annual economic value of $15 billion in the U.S. Additionally, their honey is valued at $150 million annually. In Fall 2006, commercial beekeepers observed sudden mass disappearances of whole colonies. By Spring 2007, the condition, dubbed Colony Collapse Disorder (CCD), raised environmental and fiscal concerns while the cause(s) continued to be sought. Forensic examinations of hive samples did not reveal a singular cause of CCD. The results pointed to a collection of detrimental factors affecting …
