摘　　要：低温胁迫对植物的地理分布和生长发育有着重要影响。当植物受到低温胁迫时,转录因子通过结合基因启动子上的顺式作用元件激活低温响应基因的表达,从而调控植物体内的信号转导通路来提高植物的耐低温性。着重主要介绍了AP2/ERF、NAC、WRKY、MYB、bZIP、ZFPs等转录因子家族参与植物低温胁迫响应的最新研究进展,并提出了一个转录因子通过与其他因子和启动子元件互作的方式参与低温胁迫响应的基因表达调控网络。Cold stress has an important influence on the geographical distribution and growth of plants.Under cold stress,transcription factor activate the cold responsive gene expressions by binding to the cis-acting elements of gene promoter,therefore improving the cold resistance of plants by regulating signal transduction pathways in plants.This review focuses on recent research progresses on transcription factors AP2/ERF,NAC,WRKY,MYB,bZIP,and ZFPs involved in plant cold stress,and proposes a regulatory network that transcription factors participates in the cold stress by interacting with other factors and promoter elements while in gene expression.
