植物硝酸盐转运体的功能及其调控
Function and regulation of nitrate transporters in plants
摘要
Abstract
Nitrate (NO3-) is not only a major inorganic form of nitrogen absorbed by plants, but also a state remobi-lized among different organs of plant.Higher plants use nitrate transporter (NRTs) to uptake and transport nitrate ions.Up to date, many researches focused on NRT1.1, NRT1.2, NRT2.1, while little is known about the functions and regulatory mechanisms of other forms. In the plant system as a whole, the absorption and transportation of nitrate is a continuous process. The coordination of this process with other vital processes is still need to be further investigated. In this paper, the structure, biological function and regulation of NRTs are reviewed. This paper aimed at expounding the molecular and physiological mechanisms of absorption and transportation of nitrate in plants, and provides guidance for improvement of crops'nitrogen efficiency.关键词
