摘要

Dear Editor, SWEETs represent a novel family of membrane sugar transporters that have been identified in plants,worms,and mammals.They selectively transport mono-or disaccharides across plasma or intracellular membranes,and are involved in a number of essential physiological processes [1].The functions of SWEETs are best characterized in plants.In Arabidopsis thaliana,AtSWEET1/4/5/7/8/13 mediate glucose efflux [1],AtSWEET11/12 function as sucrose transporters [2],and AtSWEET17 permeates fructose [3,4].
