Genome-wide analysis of the DREB family genes and functional identification of the involvement of BrDREB2B in abiotic stress in wucai (Brassica campestris L.)

Abstract: Dehydration responsive element binding protein (DREB) is a significant transcription factor class known to be implicated in abiotic stresses. In this study, we systematically conducted a genome-wide identification and expression analysis of the DREB gene family, including gene structures, evolutionary relationships, chromosome distribution, conserved domains, and expression patterns. A total of 65 DREB family gene members were identified in Chinese cabbage (Brassica rapa L.) and were classified into five subgr… Show more

“…These results above suggested that DREB gene families were expanded mainly by WGD or segmental duplications (in particular) and tandem duplications, and this might have enhanced the wide adaptability of cotton. Similarly, WGD, segmental duplications, and/or tandem duplications have been identified during the evolution of the S. spontaneum , B. campestris , and soybean [ 20 , 43 , 44 ]. It is known that the tandem duplications play the adaptively important roles in the evolution of abiotic stress responsive genes.…”

“…ERF transcription factors also play important regulatory roles in plant responses to abiotic stresses [ 47 ], including drought [ 48 , 49 ], cold [ 50 , 51 ], and salt [ 52 , 53 ]. In this study, we found that most PagERF promoters contain DRE elements, ABRE elements, and other elements involved in the response to stress ( Figure 6 ); some PagERF promoters also contained MYB binding sites associated with the response to drought.…”

“…Previous studies have confirmed that overexpression of SlAREB1 can enhance tomato tolerance to salt stress [ 58 , 59 ]. The DREB transcription factor belongs to the AP2/ERF (APETALA2/ethylene-responsive factor) family, which binds to the dehydration response element (DRE) to regulate the expression of a series of downstream genes and enhance plant resistance to abiotic stress [ 60 ]. The K + /Na + ratio in the cytoplasm is a determining factor for plants to improve Na + tolerance [ 61 ].…”
