- Abstract
The article offers information on the catalases of phytopathogenic fungi. It examines that factors of virulence and resistance to fungicides by catalases. Catalases convert water to hydrogen peroxide and water and their primary function to protect cell DNA, proteins and lipids. It is mentioned that the activities of catalases might predict the virulence or resistance to fungicides of a specific pathogen. Catalases favor the resistance to chemical agents by pathogen increase and implantation of the microorganism, disease development and destruction of plant tissue. Hydrogen peroxide induces cell death, and on the other hand, produces citotoxic effect based on its production.
