Crop diseases cause large yield losses and are the major factors which limit the increase of agricultural production. The question of the lectins participation in the pathogens recognition and the formation of protective reactions of the plant is relevant. Changes in lectin activity of different cell fractions in organs of winter wheat seedlings (Triticum aestivum) under biotic stress were investigated. It was established that lectin activity of cell walls and cell organelles of uninfected seedlings was lower than lectin activity of both fractions of infected with eyespot causal agent seedlings. Lectin activity dynamics of various cell fractions was different under infection. Reaction response was more expressed in wheat seedlings of relatively resistant to pathogen variety Renan than in seedlings of susceptible variety Myronivska 808. Identified changes in activity of lectins of various cell fractions of both organs indicate their involvement in formation of protective reactions under the pathogenesis.

Key words:    cell walls and cell organelles, eyespot causal agent, changes in lectin activity, pathogenesis, winter wheat, seedlings
