Abstract
It was shown that cell surface lectins of Azospirillum brasilense sp7 and Azospirillum lipoferum 59b are involved in the specific adhesion of these bacteria to wheat roots. Comparative studies of the interactions of the lectins of homologous and nonhomologous strains of azospirilla with different root fractions of Saratovskaya 29 wheat showed that interactions of the lectins of homologous and nonhomologous strains of azospirilla with the surface of wheat roots had both specific and nonspecific nature. The interaction intensity was different in the two species of azospirilla studied. Bacterial lectins were shown to interact with wheat root lectin.
