Activation mechanism of intra-and extracellular cotton peroxidases by wilt infection

It was found that intra- and extracellular cotton peroxidases were involved in infection by the phytopathogen Verticillium dahliae. Extracellular peroxidase was more active. Its activity was greater in resistant variety AN-Bayaut-2 than in susceptible C-4727. It was found that activation in the susceptible cotton variety caused by pathogen infection occurred via de novo protein synthesis whereas in the resistant variety it occurred via synthesis of new ones and activation of already existing peroxidases.
