摘要:

植物DREB转录因子属于AP2/ERF转录因子家族,能够特异性地结合启动子区的DRE/CRT顺式作用元件,调控下游逆境应答基因的表达,从而在植物应对低温、干旱、高盐等非生物胁迫中发挥重要作用。围绕对DREB转录因子的调控,重点介绍了其表达、功能、降解等过程中涉及的调控机理方面的研究成果,并对DREB转录因子未来的研究方向进行了展望。

关键词: DREB, 表达, 调控, 修饰

Abstract:

Plant DREB transcription factor, one subfamily member of AP2/ERF family, can specially bind to DRE/CRT cis\|acting element. They play important roles in plant resistant to abiotic stresses, such as cold, drought, salt, through regulating the expression of stress\|responsive genes. This paper reviewed the regulating and controlling role of DREB transcription factor, emphasized in introducing the research findings made in regulating and controlling mechanism during the process of its expression, function, degradation; and also prospected the future orientation for transcription factor research.

Key words: DREB, expression, regulation, modification
