Background and aims Hydrogen sulfide (H2S) acting as the third gasotransmitter following NO and CO has important physiological functions in both animals and plants. In plants, H2S plays a critical role in alleviating toxicity of Cd stresses. It is well known that Calcium-Dependent Protein Kinases (CDPKs) can regulate cell recognition and signal transduction through reversible protein phosphorylation, but how CDPKs regulate H2S signal remains unclear.
