摘要:
非生物胁迫严重影响植物的生长发育及农作物的产量。植物AREB(ABA responsive element binding protein)/ABF (ABRE binding factors)转录因子是特异识别ABA响应元件(ABA-responsive element,ABRE)的一类碱性亮氨酸拉链蛋白,参与调控ABA响应基因的表达,在植物响应非生物胁迫的过程中具有重要作用。本文介绍了ABF转录因子的结构特征及识别的顺式作用元件、调控修饰途径及其在应答非生物胁迫中的作用,为应用ABF转录因子培育优良抗逆作物品种奠定基础。

Abstract:
Abiotic stress seriously affects plants growth and crop yield. Plant AREB (ABA responsive element binding protein)/ABF(ABRE binding factors) transcription factors are a type of leucine zipper protein that specifically recognizes ABA-responsive element (ABRE). They are involved in regulating the expression of ABA-responsive genes and play a crucial role in the response to abiotic stress in plant.This article introduced the structural characteristics of ABF transcription factors, the identified cis-acting elements, regulatory modification pathway and their roles in response to abiotic stress. This review might contributes a theoretical foundation for the application of ABF transcription factors to breed excellent cultivars?with stress tolerances.
Key words:  AREB/ABF transcription factors  regulatory modification  abiotic stress  ABA  plant
