Hydrogen sulfide (H2S) is a gaseous signaling molecule that regulates diverse cellular signaling pathways through persulfidation, which involves the post-translational modification of specific Cys residues to form persulfides. However, the mechanisms that underlie this important redox-based modification remain poorly understood in higher plants. We have, therefore, analyzed how protein persulfidation acts as a specific and reversible signaling mechanism during the abscisic acid (ABA) response in Arabidopsis (Arabidopsis thaliana). Here we show that ABA stimulates the persulfidation of

半胱氨酸脱硫酶和NADPH氧化酶的过硫化修饰控制保卫细胞脱落酸信号
硫化氢(H 2 S)是一种气体信号分子,通过过硫化作用来调节多种细胞信号传导途径,这涉及特定Cys残基的翻译后修饰以形成过硫化物。然而,这种基于氧化还原的重要修饰基础的机制在高等植物中仍然知之甚少。因此,我们已经分析了蛋白质过硫化如何在拟南芥(Arabidopsis thaliana)的脱落酸(ABA)反应过程中作为一种特定且可逆的信号转导机制。在这里,我们证明了ABA刺激了
