Genotypic dependent effect of exogenous glutathione on Cd-induced changes in proteins, ultrastructure and antioxidant defense enzymes in rice seedlings

► GSH alleviates Cd-toxicity, ameliorates Cd-induced damages on leaf/root ultrastructures. ► Nine proteins in roots were identified, whose expression down/up-regulated by Cd in Cd-sensitive/tolerant rice genotypes, respectively, and induced by GSH addition. ► Eight proteins in leaves with expression of increase in Cd-tolerant genotype but down-regulate/unchange in Cd-sensitive genotype.
