Unraveling the protective role of sulfide signaling in plants against climate-induced abiotic stress.

Hydrogen sulfide (H2S) regulates plant responses to climate-induced abiotic stresses, with protein persulfidation as the main mechanism.

• Why it matters: Understanding how plants tolerate environmental stressors is crucial for improving crop resilience amid climate change.
• What they did: The review summarizes current knowledge of endogenous H2S sources, mechanisms of action, and its role in alleviating stresses like drought, soil salinization, and thermal stress through protein persulfidation.
• The result: H2S's regulatory effects on physiological and molecular responses may enhance plant stress tolerance and crop resilience under changing environmental conditions.
