Abstract

Abstract: Sucrose is the primary product of photosynthetic CO₂ fixation which is used for the distribution of assimilated carbon within higher plants. The transmembrane transport of sucrose requires the participation of sucrose transporters. Currently,studies have shown that sucrose transporter are widely present in higher plants and played main role in seed,flower,leaf cells,phloem,root and other organs. By the way of subcellular localization,sucrose transporters have been found mostly to be located in the cell membrane and vacuole membrane. In this paper,we review the progresses on different aspects of SUTs,such as the protein structure,classification,physiological functions,functional verification and subcellular localization;then we discussed the research significance and remained problems in studying sucrose transporter for better understanding the action mechanism of sucrose transporter proteins in plants.

Key words: sucrose transporter, structure, classification, function, localization
