植物硅转运蛋白研究进展

Research Advances on Silicon Transporters in Plants

摘要:

硅作为一种非金属元素，不仅在植物的生长发育过程中发挥重要的功能，同时在植物抵御生物和非生物胁迫中也发挥着重要的作用。研究表明硅的吸收与转运由硅转运蛋白参与完成，根据对硅酸的转运特性主要分为硅内流转运蛋白和硅外流转运蛋白。该文对已鉴定出的硅转运蛋白的结构特点、功能、调控方式进行了总结，对植物吸收与转运硅的过程进行了系统性解析，提出了存在的问题，并对未来的研究方向进行了展望。

Abstract:

Silicon, as a non-metallic element, not only plays an important role in plant growth and development, but also involves in biotic and abiotic resistance. Silicon transporters are directly responsible for the absorption and transportation of silicon, which could be mainly classified into silicon influx transporters and silicon efflux transporters according to their transport properties. In this review, the structural characteristics, functions, and regulatory modes of the reported silicon transporters are summarized, the process of silicon uptake and transport in plants are described, the existing problems are put forward, and the future research directions is also prospected.
