摘　　要：植物碳水化合物在“源流库”不同组织器官中的合成、代谢及转运对有机体维持正常生命活动至关重要。其中,以蔗糖、葡萄糖和果糖为代表的糖类短距离或长距离运输在源到库的“流”中占有关键作用,在此过程中,碳水化合物的转运与分配需要多种细胞糖转运体的协同参与。糖外排转运蛋白(SWEETs)能够调节植物营养的分配、利用,决定组织器官的生长与发育,维持或调节细胞糖响应浓度,调节寄主-病原体相互作用等生物与非生物胁迫。本综述介绍了SWEETs基因家族基本结构特征、生理功能和胁迫应答等方面的研究进展,对植物细胞生理功能的理解和生物育种等研究具有重要意义。The synthesis,metabolism and transport of plant carbohydrates in different tissues and organs of“source-sink-flow”are essential for the normal life activities of organism.Among them,the short-distance or long-distance transport of sugars,such as sucrose,glucose and fructose,play a key role in the“flow”from source to sink,the transport and distribution of carbohydrates require the synergistic involvement of multiple cellular sugar transporters.Sugars will eventually be exported transporters(SWEETs)exhibit diverse functions,participating in regulating important physiological processes such as nutrient allocation,utilization,tissue organ growth,and development,as well as responding to biotic and abiotic stress by maintaining or regulating cellular sugar levels.This review summarizes the research progress in the basic structural characteristics,physiological functions,and stress responses of the SWEETs gene family,which holds significant implications for understanding plant cellular physiology and research areas like biotic breeding.
