Abstract:
DREB2s is a plant-specific transcription factor, which belongs to the AP2/EREBP transcription factor family.
DREB2s plays an important role in regulating abiotic stress (drought, high salinity, low temperature, and high temperature) responsive gene expression. The genetic structure of
DREB2 transcription factor is slightly different, as is its response to abiotic stress. We reviewed the structural features of the
DREB2s proteins and their responses to various abiotic stresses, and the recent advances in the molecular mechanism of
DREB2s at the level of transcription and post transcriptional regulation of gene expression, which will provide a theoretical basis for understanding the gene function, molecular mechanism and genetic engineering approach to improving plant abiotic stress resistance of
DREB2s.
