摘要
养分离子的跨膜转运是细胞获取养分的重要环节 ,亦是植物在组织和器官水平上进行养分吸收运移的基础。文中综述了拟南芥中养分离子转运蛋白在基因克隆、序列与结构分析、功能鉴定、表达与调控方面的研究进展 ,其中着重讨论了这些转运蛋白在氮、磷和钾等营养元素吸收、运输、分配中的作用。
Transporting of ions across plasma membrane is an important process of nutrient acquisition for plant not only at cell level but also at tissue and organ levels.In this paper, we summarized the research advances on the gene cloning, sequence and structure analysis , function identification,expression and regulation of the ion transporting proteins and focused on their functions in the process of absorption, distribution and translocation of nitrogen, phosphorus , potassium and other nutrients in Arabidopsis thaliana.
