Regulatory network established by transcription factors transmits drought stress signals in plant

Abstract Plants are sessile organisms that evolve with a flexible signal transduction system in order to rapidly respond environmental changes. Drought, common abiotic stress, affects multiple plant developmental processes especially growth. In response drought an intricate hierarchical regulatory network is established survive from the extreme environment. The transcriptional regulation carried out by transcription factors (TFs) most important step for establishment of network. this review, we summarized almost all TFs have been reported participate tolerance (DT) plant. Totally 466 86 species mostly belong 11 families collected here. This demonstrates these main regulators DT. built direct protein-protein interaction or mutual TFs. receive upstream signals possibly via post-transcriptional and output downstream targets binding their promoters regulate gene expression.
