摘　　要：液泡是细胞内一种可以储存多种营养物质以及代谢产物的细胞器。为了抵御高盐、干旱和重金属毒害等非生物胁迫,植物可以通过将细胞质中过量积累的Na^+、K^+、Ca^2+和其他金属阳离子区域化至液泡中,以此来维持正常的细胞膨压并提高植物的抗逆性。液泡膜阳离子转运蛋白种类丰富,能够调控细胞中不同无机离子的转运和区域化。鉴于此,对定位于液泡膜的不同阳离子转运蛋白在植物响应逆境胁迫中的作用进行了简要概述。Vacuole is a kind of organelles that can store a variety of nutrients and metabolites in cells.In order to resist the harsh environments such as salinization,drought and heavy metal pollution,plants can change the turgor and improve its stress resistance by compartmentalizing the excess ions,such as Na^+,K^+,Ca^2+ and other metal cations,in the cytoplasm into vacuoles.There are many tonoplastcation transporters regulated the transport and compartmentalization of different ions.In view of this,we mainly summarized the roles of different tonoplast cation transporters in plants responding to stresses in this review.
