一氧化氮(NO)作为一种重要的信号分子,不仅参与植物的种子休眠和萌发以及根的形态建成等生长发育过程,还参与调节植物细胞的气孔运动以及植物抗逆应答反应.该文结合最新研究成果,总结了植物NO信号调控机理的研究进展,主要包括NO合成途径、信号转导途径及其与其它信号分子之间的交叉反应和对植物抗逆的调控作用等.%Nitric oxide (NO),as an important signal molecule,is involved in regulating every aspect of plant growth and development,such as seed germination and dormancy,root morphogenesis,and ion absorption.It also mediates stomatal opening and closing and plant resistance to external stimuli.Here,we summarize recent studies of the regulation mechanism of plant NO signaling within the last 10 years,including the new discovery of the NO synthesis pathway,the regulation of NO signal transduction,its interaction with other signal molecules,and NO regulation of plant defense.
