摘　　要：碱性亮氨酸拉链(Basic region/leucine zipper motif,bZIP)类转录因子是近年来研究较多的转录因子家族之一,参与多种生物学过程,对植物的抗病性、抗寒性、抗旱性和耐盐性等逆境均具有重要的调控作用。文章通过对植物bZIP类转录因子的分布、结构、分类及其在植物逆境胁迫中的作用等最新研究进展进行了综述,提出今后可在全基因组层面上发掘更多的bZIP转录因子,并通过定点突变、转基因等手段创造bZIP的突变体,促进对bZIP表达调控机制的认识,进而了解bZIP转录因子对抗逆相关基因的调控机理,并通过基因工程手段提高植物的抗逆性,培育多抗性植物新品种。Basic region/leucine zipper motif （bZIP） transcription factors are one of the most extensively investigated transcriptional factor families in recent years, which are involved in many biological functions and play an important role in plant stress resistance such as disease resistance, cold resistance, drought resistance, salt tolerance, and so on.. This paper summarized the advances in distribution, structure, classification and function, as well as the role in plant stress tolerance of bZIP transcription factors. It was proposed that more whole-genome based bZIP transcription factors should be explored, and bZIP mutant could be constructed by site-directed mutation and transgenosis in order to understand the mechanism of bZIP transcription factors that＇s regulating stress related genes, hence new multi-resistance plant varieties could be bred through improving plant stress resistance by genetic engineering.
