摘要： 在概括高等植物体内硅含量、形态、分布及作用等特征的基础上，分析了硅吸收部位、吸收机制以及水稻硅吸收突变体筛选的研究，详细综述了到目前为止在4种高等植物中发现的9种（其中水稻OsLsi1、OsLsi2、OsLsi6，玉米ZmLsi1、ZmLsi2、ZmLsi6，大麦HvLsi1和HvLsi2，南瓜CmLsi1）硅转运蛋白的吸收转运活性等特征，从植株水平上归纳了水稻、玉米和大麦体内多种硅转运蛋白分工合作的硅吸收转运机制。为了加深了解硅转运蛋白及其机理亟待拓宽研究对象。

Abstract: This article generalized the characteristics of silicon content, form, distribution and function in higher plant, expounded the researches about the silicon uptake site in roots, the uptake mechanisms and selecting the rice mutants defective in Si uptake. The characteristics were reviewed in details such as activities of 9 silicon transporters discovered in 4 kinds of higher plants, including OsLsi1, OsLsi1, OsLsi1 in rice; ZmLsi1, ZmLsi1, ZmLsi1 in maize; HvLsi1 and HvLsi2 in barley, CmLsi1 in pumpkin. It summarized the specialization and cooperation mechanisms of various silicon transporters on the whole level of the rice, maize and barley. It needed to broaden the research objects in order to correctly and fully understand the transporters and its mechanisms.
