摘要:

DREB转录因子即干旱应答元件结合蛋白质,它能特异结合启动子中含有 DRE/CRT 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。介绍DREB转录因子与DRE顺式作用元件的关系,DREB 转录因子与 DRE 元件的结合特异性,DREB 的结构特点和功能,DREB 转录因子的表达调控,DREB 转录因子的克隆及鉴定等方面的研究进展,简述 DREB 转录因子对调控逆境诱导基因的表达具有非常重要的作用,在提高植物综合抗逆性方面将有巨大的应用前景。同时,指出 DREB 转录因子在信号转导、作用机理及基因表达等方面的复杂性。

Abstract: DREB transcription factor is a dehydration responsive element (DRE) binding protein. It 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. In this paper we described the relation between DREB transcription factor and DRE/CRT cis-acting element, the functional and structural character, and expression and regulation of DREB. We also briefly introduced the progress of research on DREB gene cloning and identification. DREB transcription factor plays an important role in the expression of many stress-inducible genes in plant, so it thus shows a very broad application future in aspect of increasing strong tolerance to stress. At the same time, we described the DREB complexity in signal transduction and the mechanism for action and expression of gene.
