Theses and Dissertations--Plant and Soil Sciences
Drought stress is considered one of the most devastating abiotic stress factors that limit crop productivity for modern agriculture worldwide. There is a large range of physiological and biochemical responses induced by drought stress. The responses range from physiological and biochemical to regulation at transcription and posttranscriptional levels. Post-transcription, the products encoded by eukaryotic genes must undergo a series of modifications to become a mature mRNA. Polyadenylation is an important one in terms of regulation. Polyadenylation impacts gene expression through determining the coding and regulation potential of the mRNA, especially when different mRNAs from the same gene may be polyadenylated …

For millennia humans have utilized plant specialized metabolites for health benefits, fragrances, poisons, spices, and medicine. Valued metabolites are often produced in small quantities and may command high prices. Understanding when and how the plant synthesizes these compounds is important for improving their production. Phytohormone signaling cascades, such as jasmonate (JA) activate or repress transcription factors (TF) controlling expression of metabolite biosynthetic genes. TFs regulating specialized metabolite biosynthetic genes can be manipulated to engineer plants with increased metabolite production.
WRKY transcription factor are known components of both JA signaling cascades and regulation of specialized metabolism. The presence of WRKY binding …
