摘要：The branching characteristics of plants represent crucial agronomic traits that significantly influence both yield and economic value. The formation of branches involves several stages, including the initiation of axillary meristems and the activation and continued growth of lateral buds. These processes are collaboratively regulated by genetic factors, hormones, nutritional availability, and environmental conditions. Recently, sucrose has emerged as a significant factor impacting plant branching characteristics. Sucrose not only serves as a carbon source, providing essential nutrition and energy for branching growth, but also integrates multiple regulatory factors to jointly influence branching development. This review summarizes the structural enzyme genes involved in the sucrose synthesis pathway and the key co-factors in signal transduction pathways, the interactions between sucrose and plant hormones and transcription factors, and the regulatory role of sucrose metabolites in plant branching. Furthermore, it highlights critical issues that require further investigation regarding the role of sucrose in regulating branching.
