Progress in Research Techniques of Protein S-nitrosylation and Its Role in Plant Disease Resistance

S-nitrosylation,the covalent attachment of an Nitric oxide(NO) moiety to Cys residues of proteins,resulting in the formation of S-nitrosothiols(SNO),is a prevalent posttranslational protein modification involved in redox-based cellular signaling.S-nitrosylation has been shown to regulate the function of many proteins which are involved in a wide array of cellular activities.The growing body of evidence now suggested that S-nitrosylation may also have a centrol function in plant disease resistance.The basic concepts of S-nitrosylation,the detection methods,functional studies and the recent progress of S-nitrosylation in plant disease resistance were summarized.
