摘　　要：碱性亮氨酸拉链(basic region/leucine zipper motif,bZIP)类转录因子是研究最多的转录因子基因家族之一,在所有的真核生物中都存在含有bZIP结构域的蛋白,且在已经测序完成的植物基因组中含有大量的bZIP类转录因子.bZIP类转录因子主要定位于细胞核中,参与多种生物学过程,包括植物生长、花发育、种子成熟、衰老、光信号、损伤、病菌防御以及对各种环境胁迫的响应等.本文对国内外近年来有关植物bZIP类转录因子在分布、结构、分类及其与植物生长发育、植物激素、抗病性、抗逆性以及基因互作等方面的研究进展进行综述并对该基因家族研究过程中存在的问题进行了讨论.Proteins with basic region/leucine zipper motif（bZIP） domains are present in all eukaryotes and belong to one of the most extensively investigated transcriptional factor families.Now,plants which complete genome sequences was sequenced,include plenty of bZIP transcriptional factors.bZIP transcriptional factors,located in nucleolus,are involved in various biological functions such as plant development,flower development,seed maturation,senescence,light signaling,wounding,pathogen defence,and responsive to various environment stress,and so on.This paper focuses on the most advanced research in plant bZIP transcription factors,summarizes systemic the distribution,sorts,structures and the relation with plant developing,plant hormones,disease resistance,and stress resistance and gene interactions.In addition,the existing problems of the transcript factor study are put forward.
