摘要: SWEETs是一类新发现的双向糖转运蛋白, 其家族成员在各种生物体中广泛存在。在植物中, 不同进化分支的SWEETs成员对转运已糖(葡萄糖、果糖和半乳糖)和蔗糖具有特异性, 通过特定的糖信号转导对生长发育和生理过程产生影响。该文重点综述了SWEETs转运蛋白响应生物和非生物胁迫的功能, 系统总结了SWEETs在转录水平、蛋白翻译后水平以及多种信号转导途径中响应环境胁迫的调控机制, 旨在为揭示SWEET转运蛋白的复杂生物学功能及其作用机制提供新的视角, 为未来植物抗逆研究和高产抗病作物分子育种提供有价值的参考。

关键词: 糖转运, SWEET, 胁迫响应, 调控机制

Abstract: SWEETs are a recently discovered family of bidirectional sugar transporters that are widely present in all organisms. Their high substrate specificity for hexoses (such as glucose, fructose and galactose) and sucrose in different clades underlines their significance in regulating sugar signaling during various developmental and physiological processes in plants. This review primarily focuses on how SWEETs precisely respond to various biotic and abiotic stresses. We summarized systematically the regulatory mechanisms of SWEETs in response to environmental stresses at both the transcriptional level and the post-translational level and in multiple signal transduction pathways. This review aims to provide a novel perspective and deeper understanding of the complex biological functions and regulating mechanisms of SWEET transporters, and provides valuable information for future research on plant stress resistance and molecular breeding crops with high yield and disease resistance.

Key words: sugar transport, SWEET, stress response, regulating mechanism
