Nitric oxide (NO) as an important secondary messager plays crucial roles in modulating stomatal movement, especially abscisic acid (ABA)-induced stomatal closure. Accumulating evidence indicates that NO positively and negatively regulates guard cell ABA signaling. NO is also implicated in stomatal closure mediated by hydrogen sulfide, small peptides, polyamines, and methyl jasmonate. In this review, we summarize recent advances on the roles and the underlying mechanisms of NO in regulating stomatal closure in plants.
一氧化氮(NO)作为一种重要的次级信使,在调节气孔运动中起着至关重要的作用,尤其是在脱落酸(ABA)诱导的气孔关闭中。越来越多的证据表明,NO 正向和负向调节保卫细胞的 ABA 信号。NO 也参与了由硫化氢、小肽、多胺和茉莉酸甲酯介导的气孔关闭。在这篇综述中,我们总结了 NO 调节植物气孔关闭的作用和潜在机制的最新进展。
