摘　　要：植物的分枝特性是重要的农艺性状,可影响植物的产量和价值。植物的分枝特性受多种因素共同影响,蔗糖是最近受关注最多的影响植物分枝特性的研究热点。蔗糖不仅可以作为碳源为植株的分枝生长提供能量,还是植物生长发育的重要信号分子。本综述归纳了蔗糖促进分枝的主要信号途径,其中,独脚金内酯、生长素和细胞分裂素是蔗糖促进分枝过程中最为重要的3类激素,TB1(teosinte branched 1)、BRC1(branched 1)等转录因子也发挥着重要作用。本文可为植物分枝理论和构建植物合理群体提供参考。Shoot branching is an important agronomic trait of plant architecture because it substantially affects the yield and value of the plant.Branching characteristics are affected by many factors,and sucrose is the most popular research topics affecting the branching characteristics of plants.A certain number of studies have shown that sucrose not only serves as a carbon source to provide energy for the meristematic growth of plants,but also is an important signaling molecule.In this review,the main pathways through which sucrose promotes branching are summarized.Among them,strigolactone,auxin,and cytokinin are the most important hormones in the process of sucrose promoting branching,and transcription factors such as teosinte branched 1(TB1)and branched 1(BRC1)also play an important role.This paper provides a basis for the theory of plant branching and constructing a reasonable plant population.
