Salicylic acid (SA), a naturally occurring plant phenolic is
considered as a hormone like endogenous regulator. It could
ameliorate the oxidative stress damaging effects of heavy
metals like Cd in rice. SA strongly inhibited Na+ and Cl
accumulation, stimulated N, Mg, Fe, Mn and Cu concentrations
of salt stressed maize plants. One of the pathways of
SA biosynthesis is located in the chloroplasts in processes
catalyzed by some enzymes so, it affects leaf photosynthesis
