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

Hydrogen sulfide (H2S) enhances plant resilience to climate-induced abiotic stresses through protein persulfidation, with a significant role in stress regulation.

• Why it matters: Understanding H2S signaling is crucial because climate change intensifies environmental stresses that threaten crop productivity and food security, yet the mechanisms remain unclear.
• What they did: The review synthesizes current knowledge on endogenous H2S sources, mechanisms like protein persulfidation, and its role in mitigating stresses such as drought, salinity, heat, and elevated CO2 in plants.
• The result: This insight into H2S’s regulatory functions offers potential strategies to improve crop tolerance and resilience amid climate challenges, supporting sustainable agriculture.
