“…These studies have identified the conserved, as well as, species-specific regulatory and functional drought-responsive genes, including osmoprotectants and ABA biosynthesis, late embryogenesis abundant (LEA) and chaperone, ROS-related, ion homeostasis, and signaling genes. Additionally, key TFs regulating drought-responsive gene transcription have also been identified, such as MYB, MYC, DREB/CBF (drought-responsive cis -element binding protein/C-repeat-binding factor), ABF/AREB, NAC, and WRKY TFs ( Stockinger et al, 1997 ; Sakuma et al, 2006 ; Tran et al, 2007b ; Nakashima et al, 2009 ; Ishida et al, 2012 ; Figure 2 ). Corresponding cis -motifs, DRE/CRT and ABRE (ABA-responsive cis -element), have also been discovered in the promoters of many stress-responsive genes ( Yamaguchi-Shinozaki and Shinozaki, 2006 ).…”

Water stress adversely impacts many aspects of the physiology of plants, especially photosynthetic capacity. If the stress is prolonged, plant growth, and productivity are severely diminished. Plants have evolved complex physiological and biochemical adaptations to adjust and adapt to a variety of environmental stresses. The molecular and physiological mechanisms associated with water-stress tolerance and water-use efficiency have been extensively studied. The systems that regulate plant adaptation to water stress through a sophisticated regulatory network are the subject of the current review. Molecular mechanisms that plants use to increase stress tolerance, maintain appropriate hormone homeostasis and responses and prevent excess light damage, are also discussed. An understanding of how these systems are regulated and ameliorate the impact of water stress on plant productivity will provide the information needed to improve plant stress tolerance using biotechnology, while maintaining the yield and quality of crops.

“…These transcription factors function in drought tolerance of several plant species, including crops and woody plants [4,5,[108][109][110][111]. The drought-responsive cis-element (DRE/CRT/LTRE, 5 0 -TACCGA-CAT-3 0 ) has been identified in the promoter regions of drought-, salinity-, and cold stress-inducible genes.…”

“…Transcription factors play key regulatory roles in plant salt stress adaptation coupled with sophisticated signal transduction [ 56 , 57 ]. Several genes encoding salt-responsive TFs were enriched in transcriptomic data, including MYB112 [ 58 ], HsfA6a [ 59 ], SZF1 [ 60 ], HY5 [ 61 ], and WRKY46 [ 62 ], which were upregulated in OE plants compared to Col-0 plants under salt stress.…”

Background Salt stress significantly influences plant growth and reduces crop yield. It is highly anticipated to develop salt-tolerant crops with salt tolerance genes and transgenic technology. Hence, it is critical to identify salt tolerance genes that can be used to improve crop salt tolerance. Results We report that the transcription elongation factor suppressor of Ty 4-2 (SPT4-2) is a positive modulator of salt tolerance in Arabidopsis thaliana. AtSPT4-2 expression is induced by salt stress. Knockout mutants of AtSPT4-2 display a salt-sensitive phenotype, whereas AtSPT4-2 overexpression lines exhibit enhanced salt tolerance. Comparative transcriptomic analyses revealed that AtSPT4-2 may orchestrate the expression of genes associated with salt tolerance, including stress-responsive markers, protein kinases and phosphatases, salt-responsive transcription factors and those maintaining ion homeostasis, suggesting that AtSPT4-2 improves salt tolerance mainly by maintaining ion homeostasis and enhancing stress tolerance. Conclusions AtSPT4-2 positively modulates salt tolerance by maintaining ion homeostasis and regulating stress-responsive genes and serves as a candidate for the improvement of crop salt tolerance.
