The occurrence of plant diseases severely affects the quality and quantity of plant production. Plants adapt to the constant invasion of pathogens and gradually form a series of defense mechanisms, such as pathogen-associated molecular pattern-triggered immunity and microbial effector-triggered immunity. Moreover, many pathogens have evolved to inhibit the immune defense system and acquire plant nutrients as a result of their coevolution with plants. The sugars will eventually be exported transporters (SWEETs) are a novel family of sugar transporters that function as uniporters. They provide a channel for pathogens, including bacteria, fungi, and viruses, to hijack sugar from the host. In this review, we summarize the functions of SWEETs in nectar secretion, grain loading, senescence, and long-distance transport. We also focus on the interaction between the SWEET genes and pathogens. In addition, we provide insight into the potential application of SWEET genes to enhance disease resistance through the use of genome editing tools. The summary and perspective of this review will deepen our understanding of the role of SWEETs during the process of pathogen infection and provide insights into resistance breeding.

从功能表征到 SWEET 糖转运蛋白在植物抗性育种中的应用

植物病害的发生严重影响植物生产的质量和数量。植物适应病原菌的不断入侵，逐渐形成病原相关分子模式触发免疫和微生物效应触发免疫等一系列防御机制。此外，由于与植物的共同进化，许多病原体已经进化为抑制免疫防御系统并获取植物营养。糖最终将被出口转运蛋白 (SWEETs) 是一个新的糖转运蛋白家族，起单向转运蛋白的作用。它们为病原体（包括细菌、真菌和病毒）提供了从宿主手中劫持糖分的渠道。在这篇综述中，我们总结了 SWEET 在花蜜分泌、谷物装载、衰老和长距离运输中的作用。SWEET基因和病原体。此外，我们通过使用基因组编辑工具，深入了解SWEET基因在增强抗病性方面的潜在应用。这篇综述的总结和展望将加深我们对SWEETs在病原体感染过程中的作用的理解，并为抗性育种提供见解。
