Rbohd persulfidation
WebAug 31, 2024 · Persulfidation-based modification of cysteine desulfhydrase and NADPH oxidase [Respiratory burst oxidase homolog protein D (RBOHD)] controls guard cell abscisic acid signaling (Shen et al. 2024). In light of these reports, the complete mechanism of action on stomatal aperture is still a long case, ... WebDec 1, 2024 · A simplified model of ABA and H2 S signaling activation and the interplay between persulfidation and phosphorylation of SnRK2.6. In non-stress conditions, PP2Cs block the activity of SnRK2.6 to prevent ABA signal activation. In response to drought stress, plants accumulate ABA, which is perceived by PYL/PYR receptors that bind to PP2Cs to ...
