Protein Persulfidation in Plants: Function and Mechanism.

ABSTRACT: As an endogenous gaseous transmitter, the function of hydrogen sulfide (H₂S) has been extensively studied in plants. Once synthesized, H₂S may be involved in almost all life processes of plants. Among them, a key route for H₂S bioactivity occurs via protein persulfidation, in which process oxidizes cysteine thiol (R-SH) groups into persulfide (R-SSH) groups. This process is thought to underpin a myriad of cellular processes in plants linked to growth, development, stress responses, and phytohormone signaling. Multiple lines of emerging evidence suggest that this redox-based reversible post-translational modification can not only serve as a protective mechanism for H₂S in oxidative stress, but also control a variety of biochemical processes throug
