摘要
植物分枝是决定其形态建成的重要因素,是由叶腋内的腋芽发育成枝条的过程,该过程受光照、营养及内源激素等多种因素的调控。近年来的研究发现,TCP(TEOSINTE BRANCHED1,CYCLOIDEA,PCF)转录因子家族成员BRC1/TB1可响应并整合多种信号来调控植物的分枝。该文总结了BRC1/TB1对光照、营养及不同激素的响应特征,及其在调控植物分枝过程中发挥的核心作用等研究成果,并重点对BRC1/TB1基因上下游调控网络的相关研究进行综述,且对未来的研究方向进行了展望,旨在为后续分枝调控方面的研究提供信息,也为今后创制符合人们期望的优良种质提供参考依据。
Shoot branching is an important factor in determining plant's morphogenesis,which is a process which axillary buds develop into branches,regulated by various factors such as light,nutrients and hormones.Recent studies have found that TCP(TEOSINTE BRANCHED1,CYCLOIDEA,PCF)transcription factor family member BRC1/TB1 can respond to and integrate a variety of signals to regulate plant branching.This article summarize the response of BRC1/TB1 to different environmental factors and its central role in regulating plant branching,with focus on the related research on the regulatory networks of BRC1/TB1 gene,and the future research directions have been prospected,aiming to guide the research on future regulation.
