可溶性糖的流动、分布和储存调节作物的淀粉、油、蛋白质和总碳水化合物产量，并影响许多园艺产品的质量。糖转运蛋白参与韧皮部的装载和卸载。韧皮部装载的机制已被详细研究，但韧皮部卸载和糖库器官储存的复杂和多样的机制很少被探索。碳水化合物的卸载和随后的运输机制在不同的库器官中各不相同。分析甘蔗重要贮藏器官如种子、果实或茎中碳水化合物的运输和贮藏机制，将为作物的遗传改良提供信息，从而提高作物产量和果实品质。本文综述了近年来有关糖转运蛋白在库器官中的研究进展。本文还讨论了糖转运蛋白在作物产量和糖积累中的作用，以突出它们对高效育种的贡献。
The flux, distribution, and storage of soluble sugars regulate crop yield in terms of starch, oil, protein, and total carbohydrates and affect the quality of many horticultural products. Sugar transporters contribute to phloem loading and unloading. The mechanisms of phloem loading have been studied in detail, but the complex and diverse mechanisms of phloem unloading and sugar storage in sink organs are less explored. Unloading and subsequent transport mechanisms for carbohydrates vary in different sink organs. Analyzing the transport and storage mechanisms of carbohydrates in important storage organs, such as cereal seeds, fruits or stems of sugarcane will provide information for genetic improvements to increase crop yield and fruit quality. This review discusses current research progress on sugar transporters involved in carbohydrate unloading and storage in sink organs. The roles of sugar transporters in crop yields and the accumulation of sugars are also discussed to highlight their contribution to efficient breeding.
