摘要
硝酸根不仅是植物的主要氮源,而且作为重要的信号分子,在植物的生长发育及逆境响应过程中发挥了重要作用。本文重点介绍了硝酸根作为信号分子在基因表达,根系、叶片发育,种子休眠以及逆境响应调控中作用机理的最新研究进展。
Nitrate is the major nitrogen source from soil for higher plants,also serves as an important signal molecule that regulates plant growth,development and stress responses.This review focuses on the physiological and molecular mechanisms of nitrate signal to induction gene expression,regulate root architecture and leaf expansion,relieve seed dormacy,and regulate stress response.
