Hydrogen sulfide persulfidates OAS-A1 to balance cysteine levels in regulating Arabidopsis stomatal development.

Cell reports - 24 Feb 2026

Abstract excerpt

Plants regulate photosynthesis and transpiration primarily by adjusting the stomatal aperture and density to adapt to environmental changes. O-acetylserine(thiol)lyase (OAS-TL) maintains a balance between cysteine (Cys) and sulfide metabolism. Here, we report that OAS-TL plays a critical role in stomatal development in Arabidopsis thaliana. Mutations in the OAS-TL family member gene OAS-A1 reduce Cys synthesis,...
