Abstract

Stem injection of tobacco cultivar Ky 14 with Peronospora tabacina or lead inoculation with tobacco mosaic virus induced systemic resistance to both pathogens. The treatment also elicited a systemic increase in peroxidase activity which was positively correlated with induced resistance. Increases were evident in cytosol, intercellular fluid, and cell wall fractions. Upon challenge with P. tabacina, peroxidase activity further increased in the induced plants and remained higher after challenge as compared to the control plants (...)
