摘　　要：糖转运蛋白在园艺作物生长发育、果实内糖积累以及响应逆境胁迫等方面发挥重要作用,其表达受多种因素的调节。单糖转运蛋白、蔗糖转运蛋白和SWEET(bidirectional sugar transporter,SWEET)是植物中已发现的三大类转运蛋白。就这3种转运蛋白运输活性与底物特异性、组织/器官和细胞定位进行了讨论和比较;重点介绍了园艺作物中糖转运蛋白功能和调控的最新研究进展;进一步分析糖信号、生物胁迫和非生物胁迫等对糖转运蛋白表达的调控。Sugar transporters play important roles in the growth and development,fruits sugar accumulation and response to stress in horticultural crops,and their expression is regulated by many factors. Monosaccharide transporters,sucrose transporters and SWEETs are three kinds of transporters in plants. In this study,the transport activity and substrate specificity,tissue and cell localization of the three types of transporters were discussed and compared,with emphasis on the latest progress in the function and regulation of sugar transporters in horticultural crops. What’s more,the regulation of sugar transporter expression by sugar signal,biotic stress and abiotic stress was analyzed.
