Production of reactive oxygen species (ROS) is a key signal event for methyl jasmonate (MeJA)- and abscisic acid (ABA)-induced stomatal closure. We recently showed that reactive carbonyl species (RCS) stimulates stomatal closure as an intermediate downstream of hydrogen peroxide (H2O2) production in the ABA signaling pathway in guard cells of Nicotiana tabacum and Arabidopsis thaliana. In this study, we examined whether RCS functions as an intermediate downstream of H2O2 production in MeJA signaling in guard cells using transgenic tobacco plants overexpressing A. thaliana 2-alkenal reductase (n-alkanal + NAD(P)+

反应性羰基物种介导茉莉酸甲酯诱导的气孔关闭。



活性氧(ROS)的产生是茉莉酸甲酯(MeJA)和脱落酸(ABA)诱导的气孔关闭的关键信号事件。我们最近发现,在烟草拟南芥的保卫细胞中,反应性羰基物质 (RCS) 作为 ABA 信号通路中过氧化氢 (H 2 O 2 ) 产生的中间下游,刺激气孔关闭。在这项研究中,我们使用过表达拟南芥2-烯醛还原酶( n -alkana + NAD(P) +的转基因烟草植物)检查了RCS是否作为保卫细胞MeJA信号中H 2 O 2产生的中间下游发挥作用。
