ABSTRACT Based on the research conducted so far, hydrogen sulphide (H 2 S) plays a crucial role in development and stress resilience of plants. H S, which acts as signalling molecule, responds to different stresses such heavy metals, drought, salinity, it regulates various aspects plant growth including seed germination, root development, stomatal movement, flowering, fruit ripening. Additionally, S is involved mediating legume‐Rhizobium symbiosis signalling. It modulates responses external environmental stimuli by interacting with other molecules like phytohormones, nitric oxide, reactive oxygen species. Furthermore, exerts these regulations since can modify protein functions through reversible thiol‐based oxidative posttranslational modification called persulfidation, particularly response developmental processes. As result, recognised an important emerging molecule multiple roles Research this field holds promise for engineering tolerance crops may lead potential biotechnological applications agriculture management.

The oxidative modification of specific cysteine residues to persulfides is thought be the main way by which hydrogen sulfide (H2S) exerts its biological and signaling functions. Therefore, protein persulfidation represents an important thiol-switching mechanism as other reversible redox post-translational modifications. Considering their reductase activity but also connections with proteins that generate H2S related molecules, glutaredoxin (GRX) thioredoxin (TRX)-reducing systems have potential dual roles in both depersulfidation. In this review, we will first focus on recent advances describing physiological pathways leading before discussing TRX glutathione/GRX-reducing persulfidation/depersulfidation.
