一氧化氮在植物根系生长发育过程中的作用研究进展

Roles of nitric oxide in growth of plant root

一氧化氮作为重要的气体信号分子,在植物体内参与的生理调节和信号转导功能已经成为新的研究热点。近年来,有关NO在植物根系生长发育过程中的作用研究取得了较大进展,特别是在植物根系中NO的合成和产生、NO调节植物根系生长和发育的详细具体过程以及这些过程中参与的信号转导途径等方面。本文对植物根系中NO的产生方式、NO在调节植物根系生长发育过程中的作用及其参与的信号转导途径的最新研究进展进行系统综述和展望,以加深对植物根系生长发育过程和NO信号分子功能的认识。

The roles of nitric oxide （NO）, a significant gas signaling molecule, in regulating plantphysiology progress and modulating signal transduction is being a novel hotspot ot researches. In recent decades,a great deal of important progress have been achieved on the roles of NO in the generation and development of plant root, especially on the generation of endogenous NO from plant roots, the details of NO-participated progress of root generation and development, and the related signaling pathways. In order to get further understanding of the roles of NO in plants, the update advances in studying the generation of endogenous NO in plant root and the mechanisms and signaling pathways of NO in promoting generation and development of plant root are reviewed.
