Characterization Of The Pathway Leading To The Synthesis Of Salicylic Acid In Plants Resisting Pathogen Infection., Alexander Eddo
Characterization Of The Pathway Leading To The Synthesis Of Salicylic Acid In Plants Resisting Pathogen Infection., Alexander Eddo
Electronic Theses and Dissertations
Salicylic acid is a plant hormone that accumulates with plant-pathogen interaction. This accumulation corresponds to the plant being resistant to infection and without it the plant is susceptible. In this study, primers of genes involved in the normal synthesis of SA were used in RT-PCR to compare gene expression levels in susceptible and resistant plants challenged with tobacco mosaic virus. Because SA synthesis shares chorismate as a common substrate with the synthesis of aromatic amino acids, HPLC was used to determine whether the increase in SA could be attributed to a decrease in amino acid levels. The results suggest that …

Resorts In Southern Appalachia: A Microcosm Of American Resorts In The Nineteenth And Early Twentieth Centuries., Mary F. Fanslow
Electronic Theses and Dissertations
Five resorts in East Tennessee--Montvale Springs and the Wonderland Hotel in the Smokies, Tate Spring in the Holston River Valley, Unaka Springs on the Nolichucky River, and the Cloudland Hotel at the summit of Roan Mountain--stand testament to the proposition that their region engaged fully with areas outside southern Appalachia. Their origins, clientele, and health and leisure offerings followed those of other resorts of the same time period. Moreover, the effects of national socioeconomic trends on the hotels serve as a contradiction to the stereotype of southern Appalachia as an isolated region barricaded from the outside world by mountainous topography. …
