文摘

SA inhibits CAT2 activity to increase H2O2 levels in plants upon pathogen infection H2O2 represses levels of the auxin precursor tryptophan by sulfenylating TSB1 CAT2 promotes ACX2 and ACX3 activity to increase JA accumulation CAT2 deficiency increases biotroph resistance while decreasing resistance to necrotrophs
