摘要

SWEETs是一类新发现的双向糖转运蛋白家族, 其成员广泛存在于各种生物体中并高度保守。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, 深入分析了SWEETs在转录水平、蛋白翻译后水平响应环境胁迫以及参与激素信号转导过程的调控机制, 旨在为系统揭示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。

Abstract

SWEETs are newly discovered family of sugar transporters whose members widely exist in organisms and are highly conserved and facilitate the entry or export of sugars across the plant plasma membrane. A high substrate specificity for hexoses (glucose, fructose and galactose) and sucrose in different clade SWEETs members underlines their significance in response to many developmental and physiological processes through proper sugar signaling in plants. We focus on how SWEETs precisely respond to various biotic and abiotic stresses. Furthermore, it delves into 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 complexly biological functions and regulating mechanisms of SWEET transporters, offering valuable references for future research on plant stress resistance and molecular breeding crops with high yield and disease resistance.
