摘　　要：TCP蛋白是一类植物特有的转录因子,广泛存在多个物种中。不同物种TCP蛋白数量差异较大,但都含有一个由59个氨基酸残基组成的高度保守的bHLH结构。TCP蛋白通过bHLH结构结合到基因的启动子、内含子及编码区调控下游基因表达,同时其自身的表达和活性也受多个因子的调控。近几年,随着研究的深入和生物技术的发展,TCP转录因子的上下游调控网络逐步被揭晓。本研究主要对TCP转录因子的结构、分布,其上游调控因子和调控下游基因的分子机制最新研究以及生物学功能进行综述,并对TCP转录因子未来的研究方向进行展望,为全面了解TCP类转录因子的调控网络提供参考。TCP protein is a class of plant-specific transcription factor,which is widely exists in many species.The TCP protein number in different species varies greatly,but all contain a highly conservative bHLH structure composed of 59 amino acid residues.They regulate the expression of downstream genes by directly binding to promoters,intron and coding region through bHLH structure,and its own expression and activity are also regulated by multiple factors.In recent years,with the deepening of research and the development of biotechnology,the upstream and downstream regulatory networks of TCP transcription factors have been gradually revealed.This review mainly summarized recent progress on the structure and distribution,molecular functions and regulation networks,biological function of TCP transcription factors.Finally,we provide perspectives on the future research direction that is needed to gain a deep understanding of the diverse regulatory networks of TCP TFs in plant growth and development.
