Abstract: Hydrogen sulfide(H2S),a recently characterized gaseous signal molecule,mediates stomatal closure induced by abscisic acid(ABA),ethylene(ETH)etc.,and participates in plant responses to adverse environmental stresses such as salt,drought and heavy metal stresses. H2S interacts with Ca2+,H2O2 and nitric oxide(NO)signal molecules in regulation of stomatal movement. Exogenous H2S improves the resistance to diverse stresses by increasing antioxidant enzyme activity,up-regulating gene expression,and promoting accumulation of compatible substances such as proline and soluble sugars in plants. In this paper,the latest research progresses in the functions and molecular mechanisms of H2S in the regulation of stomatal movement and response to diverse stresses are summarized and discussed.

Key words: H2S, stomatal movement, stress response, signal transduction
