...Interestingly, studies in the recent past have highlighted that ABA-dependent pathways also play an important role in the regulation of dehydrationresponsive element (DRE)-BINDING PROTEIN (DREB) transcription factors, under osmotic stress conditions [8]....

...Typically, ABA is responsible for plant defense against abiotic stresses because environmental conditions such as drought, salinity, cold, heat stress and wounding are known to trigger increase in ABA levels [8, 9]....

...Although the DREBs mediate abiotic stress-induced expression of many of the same genes as regulated by the ABIs, DREB activity is mostly ABA-independent (reviewed in Lata and Prasad, 2011)....

...In some cases, the overexpression of these transcription factors was successful to enhance salinity tolerance in crops (for review, see Lata and Prasad, 2011; Lata et al., 2011; Turan et al., 2012; Nuruzzaman et al., 2013)....

...Further, it is also proved that ABA is a major physiological signal that induces drought and high salinity responses (Gomez et al., 1988; Verslues and Bray, 2006; Farooq et al., 2009; Cutler et al., 2010; Hubbard et al., 2010)....

...The first isolated cDNAs encoding DRE binding proteins, CBF1 (CRT binding factor1), DREB1A and DREB2A were first isolated by using yeast onehybrid screening (Stockinger et al., 1997; Liu et al., 1998) from Arabidopsis....

...It was also evident from the fact that the overexpression of AtDREB2A and OsDREB2A could not induce target stress-inducible genes (Liu et al., 1998; Dubouzet et al., 2003)....

...Arabidopsis also contains two DREB2 proteins namely, DREB2A and DREB2B (Liu et al., 1998)....

...The expression of Arabidopsis DREB2A and its homologue DREB2B were induced by dehydration and high salt stress, but not by cold stress and exogenous ABA (Liu et al., 1998; Nakashima et al., 2000)....

...In the Arabidopsis thaliana genome only, nearly 1500 TFs are reported which are thought to be involved in stress-responsive gene expression (Riechmann et al., 2000)....
