[Study of chemotaxis of nodule bacteria of lupin to organic substances].
Ability of different strains (359a, 400, 176, 365a) of nodule bacteria of lupin Bradyrhizobium sp. (Lupinus), which differ in symbiotic properties (competitiveness and nitrogen-fixing activity), to chemotaxis with respect to the organic substances revealed in root exudates of lupin (aminoacids, sugars, organic acids and their salts) has been investigated. It is shown, that alongside with the substances to which rhizobia of lupin, irrespective of their symbiotic properties, show the chemotaxic reactions, there is a number of substances which are specific with respect to different strains of bacteria. Selectivity in chemotaxis of the nodule bacteria depends on their competitiveness. The relations between nitrogen-fixing activity of strains and their ability to chemotaxis are not established.
