摘要 在植物抗逆反应体系中,通过转录因子调控功能基因的表达,是植物逆境应答反应的关键环节。作为植物体内最大的转录因子家族之一,MYB(v-myb avian myeloblastosis viral oncogene homolog)类转录因子在植物抗逆胁迫过程中起着重要的作用。文章论述了MYB转录因子的结构特征、功能特性及其分子机理,并结合研究进展着重讨论了它们在植物抗逆胁迫中的作用。 Transcriptional regulation of defense gene expression is a crucial part of plant defense responses in plant defense environment stresses. As one of the largest plant transcription factor families, MYB (v-myb avian myeloblastosis viral on- cogene homolog) transcription factors play an important role in plant stress tolerance. In this paper, we review the structural features, functional characterization and molecular mechanism of MYB transcription factor family, and discuss the regulatory roles of transcription factors in plant defense responses.
