Carbohydrate binding activities of Bradyrhizobium japonicum. I. Saccharide-specific inhibition of homotypic and heterotypic adhesion.

Abstract excerpt

Bradyrhizobium japonicum (R110d) exhibited four saccharide-specific binding activities: (a) adsorption to Sepharose beads containing covalently coupled lactose; (b) homotypic agglutination through one pole of the cell (star formation); (c) heterotypic adhesion to the cultured soybean cell line, SB-1; and (d) attachment to roots of soybean plants. Each of these binding activities can be inhibited by the addition...
