Drought stress is becoming a daunting challenge for the twenty-first-century agriculture worldwide, provoking significant threat to food security as well as to growth and productivity of the major crops as global warming progresses. So developing cultivars with enhanced tolerance to drought stress appears to be the only feasible option for strengthening food security and crop productivity under climate extremes. In recent years, substantial effort has been made to unravel signalling processes underlying plant drought stress response and has confirmed the involvement of complex transcription regulatory networks. Coextensively, unravelling genetic composition of crop plants and identification of signalling cascades along with primitive molecular mechanisms through the deployment of “OMICS” techniques can expedite the piercing of drought tolerance mechanisms. Parallel to this, use of integrated studies can remarkably assist in elucidating the complex mechanism underlying drought stress tolerance, thus easing the gap between the existence and future knowledge about drought stress tolerance in plants. Regulation of drought stress tolerance in plants via certain stress-responsive genes and transcription factors (TFs) is now well established that galvanizes plants to endure unfavorable conditions. Growing evidence has also propounded that the connection between small noncoding RNAs and epigenetic regulation is imperative in the induction of drought-induced transcriptional regulation and stress memory. In this study, we intend to provide profound knowledge about the putative roles of TFs, small RNAs, and epigenetic modifications in the regulation of drought stress response and to contrive management strategies to improve plant defense against drought.
