摘　　要：DREB(Dehydration responsive element-binding protein)转录因子即脱水应答元件结合蛋白质能特异结合启动子中含有的DRE/CRT(Dehydration-responsive element/C-repeat)顺式元件,激活许多逆境诱导基因的表达,增强植物对逆境的忍耐力。文章综述了DREB类转录因子的结构特征、功能、基因表达调控机制及其在植物抗逆基因工程改良中的应用等方面的研究进展。DREB transcription factor,which was a dehydration responsive element（DRE） binding protein can specifically interact with the dehydration-responsive element/C-repeat（DRE/CRT） cis-acting element contained in the promoter region of many stress-inducible genes,and can therefore control the expression of many stress-inducible genes in plant and increase strong tolerance to drought,low temperature and high salt.The structure character,function,and the regulative mechanism of genes expression of DREB transcription factors were summarized,meanwhile,its application in plant stress tolerance genetic engineering improvement was also reviewed.
