Abstract:Shoot branching is an important factor in determining plants 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.
