Abstract
The research was aimed to study changes in peroxidase (PO) activity in the course of interaction with bacteria of various genera of Rhizobiaceae family: Rhizobium leguminosarum pea symbiont causing formation of root nodules and Agrobacterium rhizogеnes phytopathogen causing the syndrome of “hairy root”. Peroxidase activity in response to inoculation with Rh. leguminosarum virtually did not differ from control, whereas in the roots inoculated with A. rhizogines рeroxidase activity had a well-pronounced tendency to increase. It is concluded that the direction of enzyme activity change in pea seedlings interacting with Rh. leguminosarum promotes rhizobia penetration, and in the case with A. rhizogines pathogen it acts as an indicator of plant stress status.
