摘要
SWEET(sugars will eventually be exported transporter)是植物中一类重要的糖转运蛋白,通过调控蔗糖、果糖、葡萄糖、半乳糖等糖类物质的跨膜运输,介导植物根、茎、叶、花、果实、种子等器官中糖类物质的转运、积累和贮存,以参与植物各组织的生长发育和逆境胁迫的响应等生理过程.近年来,随着植物中SWEET蛋白功能的明晰,其上游调控机制的研究逐渐增加,其参与的调控网络也被逐步解析.本文总结了植物中SWEET蛋白的主要功能和近几年来其上游调控因子的研究进展,并对SWEET基因家族的研究提出了展望,旨在为进一步揭示SWEET糖转运蛋白的作用机制及其参与的分子调控网络提供参考.
Abstract
SWEET(sugars will eventually be exported transporter)proteins are important sugar transport-ers in plant.They mediate the transport,accumulation and storage of sugar substances in plant roots,stems,leaves,flowers,fruits and seeds by regulating the transmembrane transport of sugar substances including sucrose,fructose,glucose,galactose,so as to participate in the growth and development of plant tissues and the response to stress and other physiological processes.In recent years,with the iden-tification of the function of SWEET protein in plant,research on its upstream regulation mechanism has been gradually increased,and the regulatory network involving SWEET protein has been gradually clarified.In this review,we summarize the progress of the functions of SWEET proteins and their upstream regulato-ry factors in plant.We also present the prospect of research on the SWEET gene family,which may facili-tate further exploration of the regulatory mechanism of SWEET transporters in plant.
