摘要：

植物糖转运蛋白SWEET基因家族是近年来发现的一类重要的糖转运蛋白,通过调节糖分在植物体内的转运及分配等,进而在植物的生长发育、生理代谢、抗逆境胁迫等方面起着重要作用。不同物种中SWEET基因所表现的生物学功能不同,对植物生物生命活动起着重要影响。本研究报告了植物SWEET基因家族的蛋白结构、转运机制以及生物学功能的研究现状,旨在为进一步研究SWEET基因家族的其他结构与功能提供理论基础。

Abstract:

The SWEET gene family of plant sugar transporters is a class of important sugar transporters discovered in recent years, which plays an important role in plant growth and development, physiological metabolism, and resistance to stress by regulating the transport and distribution of sugar in plants. SWEET gene has different biological functions in different species and plays an important role in plant life activities. In this study, we reported the research status of the protein structure, transport mechanism and biological function of the SWEET gene family in plants, aiming to provide a theoretical basis for further study on other structures and functions of SWEET gene family.

Key words: sugar transporters, SWEET gene, structure, transport mechanism, biological function
