Regulation of gene expression by SnRK1 kinases and miRNAs during the plant stress response

Dissertation presented to obtain the Ph.D degree in Plant Physiology

Plants are constantly challenged by unfavorable conditions like water scarcity, extreme temperatures and salinity that constrain their growth. One of the established consequences of such environmental stress is a decrease in cellular energy levels. This energy deficit activates the SnRK1 (Snf1-Related protein Kinase1) kinase, which thereby triggers a major transcriptional reprogramming aimed at restoring homeostasis. Plants deficient in the SnRK1 pathway are more susceptible to stress, highlighting the importance of this kinase for acclimation and survival.(...)
