源-库互作是重要的产量决定因子，源库间碳水化合物的转运与分配机制是生命科学领域研究热点。玉米作为同化能力较强的C4植物，是研究植物碳水化合物分配的理想模型。为给玉米碳水化合物分配机制及源-库互作研究提供理论支持，通过大量文献资料的整理，分析了蔗糖长距离运输和瞬时淀粉转化形成蔗糖相关基因的调控作用，论述了同化产物分配的调控机制，对影响共质体运输基因、质外体运输基因、韧皮部结构基因和机制调控未知基因对玉米碳水化合物分配调控的分子功能方面的研究进展进行了综述，并对玉米碳水化合物分配机制研究进行了展望。

Source-sink interaction is an important yield determinant, and the carbohydrate partitioning and transfer mechanism between source and sink is a research hot spot in the field of life sciences. As a C4 plant with strong assimilative capacity, maize is an ideal model for studying carbohydrate partitioning in plants.To provide useful theoretical guidance for the research of carbohydrate distribution mechanism and source-sink interaction in maize, the regulation mechanism of assimilate product distribution is discussed through the regulation of sucrose related genes formed by long-distance sucrose transportation and instant starch transformation. This review focuses on the molecular functions that affect the regulation of carbohydrate allocation in maize by synplasmic transport genes, exoplasmic transport genes, phloem structural genes and genes whose mechanism regulation is unknown, and research on carbohydrate distribution mechanism in maize is prospected.
