摘要: 近年来,转录因子在植物防卫反应和逆境胁迫应答过程中的应用越来越广泛。本文综述了与植物逆境抗性相关的5个转录因子家族: MYB类、bZIP类、WRKY类、AP2/EREBP类和NAC类的调控机制以及它们在植物抗逆基因工程的研究进展。

Abstract: Transcription factors play important roles in the response to environment of plant. A typical higher plant transcription factor usually contains a DNA -binding domain, a transcription regulation domain, a oligomerization site , nuclear localization signals. These domains with cis-elements and regulate the expression of target genes.In this review five families of transcription factors that were related to stress-tolerance (MYB,bZIP,WRKY, AP2/EREBP and NAC), and their applications and progress in plant stress-tolerant genetic engineering were discussed.
