Lectin activity and composition in the wheat cell walls during infection fungal pathogens

Hemagglutinating activity and the molecular composition of the lectin wheat germ cells Mironovskaya 808 and Ka- zankaya 560 infected with pathogens of fungal diseases are investigated. The methods of purification and fractionation of proteins revealed an increase in the number of cell wall proteins with agglutinating activity in two varieties of winter wheat, which indicates the involvement of these proteins in the mechanisms of the protective effect of the pathogenesis. It is shown that an increase in activity of the lectin is one of the protective reaction of the organism to the action of plant pathogens and stability depend on the variety and exposure to infectious agent.
