Advances in studies on sugar transporters in ornamental plants(观赏植物糖转运蛋白研究进展)

Ornamental plants are widely used for beautifying the living environment because of their good ornamental value of flowers, leaves and fruits. Sugar transporters play critical roles in the growth and development, flowering and fruiting, and response to stress of ornamental plants. Therefore, it is of great significance to study the effects of sugar transporters on ornamental plants. Monosaccharide transporters, sucrose transporters/sucrose carriers and sugars will eventually be exported transporters are three major sugar transporters discovered in plants. The classification and basic characteristics of these sugar transporters in different ornamental plants were compared and discussed. We also summarized the function and regulation of these transporters in terms of recent research progress to provide a theoretical basis for the future use of genetic engineering technology to improve ornamental plants and enhance their ornamental and adaptive properties.(观赏植物因其花、叶、果实等具有良好的观赏价值而在环境美化中得到广泛应用。糖转运蛋白在观赏植物生长发育、开花结实以及逆境胁迫响应等方面发挥重要作用，因此，研究糖转运蛋白对观赏植物产生的影响具重要意义。单糖转运蛋白、蔗糖转运蛋白和糖外排转运蛋白是目前植物中发现的3大类糖转运蛋白。本文对这3类糖转运蛋白成员的分类及基本特性进行了比较和讨论，重点介绍了观赏植物中糖转运蛋白功能和调控的最新研究进展，以期为今后利用基因工程技术改良观赏植物并提高其观赏性及适应性提供理论依据。)
