Phytophthora Capsici In Tennessee: Fungicide Resistance, Population Genetics And Cultural Control, Timothy Brent Siegenthaler
Phytophthora Capsici In Tennessee: Fungicide Resistance, Population Genetics And Cultural Control, Timothy Brent Siegenthaler
Masters Theses
Phytophthora capsici, a plant pathogenic oomycete, is the causal agent of the vegetable disease Phytophthora blight of pepper and cucurbits. Since the identification of P. capsici in 1922, a significant amount of research has been conducted to understand its biology and disease management. Despite this, little research had been conducted on this species in the state of Tennessee. Three studies were done from 2018 to 2020, focusing on fungicide resistance, population genetics, and testing management strategies in the field. In 2018 and 2019 a total of 248 isolate of P. capsici were collected from five counties in Tennessee. These isolates …
Carbon Metabolism In Cave Subaerial Biofilms, Victoria E. Frazier
Carbon Metabolism In Cave Subaerial Biofilms, Victoria E. Frazier
Masters Theses
Subaerial biofilms (SABs) grow at the interface between the atmosphere and rock surfaces in terrestrial and subterranean environments around the world. Multi-colored SABs colonizing relatively dry and nutrient-limited cave surfaces are known to contain microbes putatively involved in chemolithoautotrophic processes using inorganic carbon like carbon dioxide (CO2) or methane (CH4). However, the importance of CO2 and CH4 to SAB biomass production has not been quantified, the environmental conditions influencing biomass production and diversity have not been thoroughly evaluated, and stable carbon and nitrogen isotope compositions have yet to be determined from epigenic cave SABs. …
