摘　　要：DREB是植物生长调节过程中重要的转录因子之一,在调控与逆境相关基因的表达、提高植物对逆境胁迫适应性中发挥重要作用。综述了DREB转录因子的结构特点,以及近年来该基因在抵御干旱、低温、高盐等非生物胁迫中作用的研究进展,指出今后应加强DREB调控下游基因及其网络的研究。Dehydration responsive element binding protein （DREB） is one of the most important transcription factors, which play an important role in regulating the expression of stress-related genes and improving their adaptability to adversity stress in plants. In this paper, structure char- acteristics, and new progresses of the effects of DREB in improving the antiabiotic stresses such as drought, low temperature, salt were summa- rized. It is the main research fields to study the downstream genes and regulating network of DREB in the future.
