摘要: TCP 基因编码植物特异性的转录因子,含有一个bHLH motif,能够与DNA结合或者产生蛋白质与蛋白质的互作。TCP基因家族在单子叶植物中有5个成员,在双子叶植物中有超过20个成员。基因的复制和多样化进化出了两类有轻微不同TCP domain 的TCP基因家族。越来越多关于TCP基因功能的研究使得将TCP基因作为工具,调整植物生长模式,产生新的农业学性状成为可能。简要概括这一家族当前的进化、调控、蛋白的生化特性,以及部分成员的生化功能,特别是在控制发育组织的细胞增殖方面。旨在为更好的调节植物的生长模式和调控植物的生理特性的研究提供思路。

Abstract: The TCP genes encode plant specific transcription factors,containing a bHLH motif,which binds with DNA or produces the interactions between protein and protein. In the family of TPC genes there are 5 members in monocotyledons and over 20 members in dicotyledons. The duplication and diversification of genes evolve two types of TCP gene families with slightly different TCP domains. Here,we just briefly summarize the evolution on the family,their regulations,the biochemical properties of their proteins,and the biochemical functions of some members,especially on cell proliferation controlling developmental tissue. Growing studies on the functions of TCP genes make it possible to adjust plants growth patterns and create new agricultural science character by regarding TCP gene as a tool,to provide ideas for better regulation of plant growth patterns and regulation of physiological characteristics of plants.

Key words: TCP gene, regulation, biochemical function
