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 …

Synthesis Of Novel Agrochemicals As Potential Plant Immunization Agents., Arrey Besong Enyong

Electronic Theses and Dissertations

The world's population is expected to grow from 6 billion to about 10 billion by 2050. The greatest population increase is expected to occur in Africa, Latin America, and Asia. To feed a world with huge increases in population and to sustain the well-being of humans, a large increase in food production must be achieved. The projected increase in food production must be accomplished on the existing cultivated areas because the expansion of new land is limited by environmental concerns, urbanization and increasing water scarcity.

Different compounds have been developed for the "immunization" of plants against several pathogens. These compounds …
