Investigation Of Shot1-Binding Atpases In Arabidopsis Thaliana, Sam Zelman
Investigation Of Shot1-Binding Atpases In Arabidopsis Thaliana, Sam Zelman
Masters Theses
Mitochondria play critical roles not only in primary metabolism as a central organelle for ATP generation, but also in responding to abiotic stresses. We identified a mutation in the MTERF18 (Mitochondrial Transcription Termination factor)/SHOT1 (Suppressor of hot1-4 1) gene in Arabidopsis thaliana that enables plants to better tolerate heat and oxidative stresses, presumably due to reduced oxidative damage, but the exact molecular mechanism of the heat tolerance is unknown. In order to reveal the stress tolerance mechanisms of mterf18/shot1 mutations, it is critical to understand the molecular defects of the mutant and to identify …

Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel
Masters Theses
Ethylene, a gaseous plant hormone, is involved in numerous plant developmental processes such as seed germination, senescence, and fruit ripening. In Arabidopsis thaliana, ethylene is perceived by a family of five membrane-bound receptors, which upon binding ethylene trigger downstream effects. At the receptor level, it is known that the coordination of a copper ion is necessary for ethylene to bind, resulting in a conformational change of the receptor and the initiation of the ethylene signal transduction pathway. Interestingly, silver ions are also able to support binding of ethylene but ethylene responses are blocked in the presence of silver. When …
