转录因子是通过转录水平或转录后水平上调控目的基因的表达来调控植物生长发育及生理代谢的.MYB(v-myb avian myeloblastosis viral oncogene homolog)转录因子是最大的植物转录因子家族成员之一,参与了细胞分化、细胞周期的调节,激素和环境因子应答,并对植物次生代谢以及叶片等器官形态建成具有重要的调节作用.文章对MYB的发现及其结构特征和功能研究进展进行综述,为进一步开展MYB基因的克隆、功能研究和利用提供参考.
Abstract:Regulation of gene expression at the transcription level or posttranscription level is one of the crucial processes involed in plant growth development and other physiological functions.As one of the largest transcription factor(TF) families,MYB(v-myb avian myeloblastosis viral oncogene homolog) implicateds in controlling cell development,cell cycling,responding to varieties of hormones and environmental signals,especially in the processes of second metabolisms.The paper reviewed the structure characters and functions of MYB so as to provide referencs for further study and utilization.
