摘　　要：Nitric oxide(NO)and hydrogen sulfide(HS)are two molecules that share signaling properties in plant and animal cells NO and H2S originate two farmilies of de rived mol ecules designated reactive nitrogen and sulfur species(RNS and RSS,respectively).These molecules are responsible for certain protein regulatory processes through posttranslational modifications(PTMs),being the most remarkable S nitrosation and persufidation,which afect the thiol group of cysteine residues.NO and H2S can also exert regulatory functions due to their interaction through the iron present in proteins that contain heme groups or iron-sulfur dlusters,as reported mainly in animal cells.Howewer,the available information in plant cells is still very limited thus far.In higher plants,NO and H2S are involved in a myriad of physiological events from seed germination to fruit ripening,but also the mec hanism of response to biotic and abiotic stress conditions.This vie wpoint manuscript highlights the functional regulatory parllelism of these two molecules which also interact with the metabolism of reactive oxygen species(ROS)in plant cells.
