Pure bacteria cultures of Azospirillum genus able to fix atmospheric nitrogen were isolated from rhizosphere soil, washed-off roots and histosphere of spring wheat plants. By their phenotype signs and the results of molecular-genetic analysis they were related to the Azospirillum brasilense species. It was shown that strain A. brasilensе 104 actively colonizes rhizospheric soil, root surface and is able to penetrate in inner plant tissues during its introduction in root system of spring wheat. The soil ascomycete Chaetomium cochliodes 3250 promotes settling down of Azospirillum bacteria in root zone of spring wheat especially in plants hystosphere which results in increasing of chlorophyll a and b content in leaves.
