A Tale Of Regulation: Analysis Of The Role Of Snrk1 And Glutathione In Autophagy In Arabidopsis Thaliana, Junmarie Soto-Burgos
Graduate Theses and Dissertations
Autophagy is a degradation process in which cells break down and recycle their cytoplasmic contents when subjected to environmental stress or during development. Upon activation of autophagy, a double membrane vesicle called the autophagosome forms around the cargo and delivers it to the vacuole/lysosome for degradation. In mammals, regulation of autophagy has been extensively studied. In plants, key regulators of autophagy have been identified, but their upstream components are poorly understood. This dissertation summarizes my efforts in studying the regulation of autophagy in Arabidopsis thaliana.
AMPK in animals, and its yeast homolog Snf1, are positive regulators of autophagy. The ...
To Grow Or Survive: Plants Modulate Brassinosteroid-Regulated Transcription Factor Bes1 During Drought To Balance Growth And Stress Responses, Trevor Nolan
Graduate Theses and Dissertations
Understanding how plants balance growth and stress responses is essential to optimize crop yield in an ever-changing environment. Brassinosteroids (BRs) regulate plant growth and stress responses, including that of drought. BRs signal to control the activities of the BES1/BZR1 family transcription factors (TFs), which in turn mediate the expression of more than 5,000 BR-responsive genes. The network through which BES1 regulates the large number of target genes and the factors that modulate BES1 during stress are only beginning to be understood. In this thesis, I investigated several mechanisms that converge on BES1 to balance BR-regulated growth and stress ...
