Abstract:

Dehydration responsive element binding(DREB)/CBF is a subfamily of the AP2/ERF(APETALA2/ethylene-responsive factor)superfamily in plant,having AP2 conserved domain and binding specifically to the dehydration response element/C-repeat(DRE/CRT)cis-elements(also known as the DNA sequence motif G/ACCGAC)found in the promoter region of stress resistance genes. Recent studies demonstrate that DREB transcription factors are involved in plant responses to drought,salt,cold,heat and other abiotic stresses,and is a key regulator in plant stress resistance. In this paper,recent progress in DREB is reviewed and several key aspects including structure,classification,family and function in abiotic stress are summarized. Combining the current bottlenecks of studying DREB transcription factors in plants,the prospects and issues in this field are also discussed. Finally,the breakthrough directions for future works are emphasized,aiming to provide a theoretical basis and guidance in screening high-quality plant resources and breeding novel varieties of crops,forests and grasses.

Key words: transcription factor, DREB/CBF, gene family, abiotic stress
