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.

Key words: horticultural crop, monosaccharide transporters, sucrose transporters, SWEETs
