Abstract – The role of weak-associated potato cell wall peroxidase in potato resistance to ring rot pathogen is shown. The data obtained showed that an addition of anti-horseradish peroxidase antibodies to resistant to this pathogen potato cv Lugovskoy cell culture caused block of weakassociated potato cell wall peroxidase activity and cell death after addition of pathogen. These data allows us to suppose that the resistance of potato to ring rot pathogen significantly depends on activity of weak-associated potato cell wall peroxidase.
