Salinity-induced changes in S-nitrosylation of pea mitochondrial proteins

► Under salinity, we study the S-nitrosylated pea mitochondrial proteins. ► In salinity, NO increases in pea leaves but not the number of S-nitrosylated proteins. ► S-nitrosylation occurs on respiratory, photorespiratory and some antioxidant enzymes. ► A differential pattern is found during plant development and salinity.
