Popis:	The activities of peroxidase isoforms and hydrogen peroxide content in leaf cuttings of wheat (Triticum aestivum L., cv. Diamant) resistant to Septoria blotch were studied during aging and following the infection with Septoria nodorum Berk. The differential activation of peroxidase isoforms was regulated by hydrogen peroxide level in the tissue. At early stages of fungus development in plant tissues, the decrease in the activities of soluble, membrane and ion-bound fractions of peroxidase elevated the level of hydrogen peroxide in infected tissues and rapidly activated peroxidase isoforms in infected tissues as compared to the aging ones even before disease symptoms appeared. The anionic peroxidases, which were first to respond to the pathogen, seem to stand for wheat resistance to fungal infections and the protection of leaf tissues from oxidative stress.
