additional information knockout of the most abundant cytosolic OAS-TL isoforms oas-a1.1 and osa-a1.2. Total intracellular Cys and glutathione concentrations are reduced, and the glutathione redox state is shifted in favor of its oxidized form. The capability of the mutants to chelate heavy metals does not differ from that of the wild type, but the mutants have an enhanced sensitivity to cadmium. The oas-a1.1 mutant plants are oxidatively stressed, H2O2 production is localized in shoots and roots, spontaneous cell death lesions occur in the leaves, and lignification and guaiacol peroxidase activity are significantly increased Arabidopsis thaliana
