Rbohd persulfidation
Webstomatal closure. Interestingly, both persulfidation on DES1 and RBOHD were redox dependent, which could be further oxidized by over-accumulated ROS and inhibit its … WebIn plants, a major driver of persulfidation is hydrogen sulfide (H 2 S), a gaseus molecule that is produced in the cytosol by cysteine-degrading enzymes 123. ABA triggers persulfidation of RBOHD. Persulfidation of RBOHD is abolished in plants expressing RBOHD C825A/C890A and those plants also exhibit reduced ROS production following ABA ...

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 ...
