B. aLectinsba possible basis for specificity in the Rhizobium-legume rootnodule symbiosis. c1974 aSoybean lectin labeled with fluorescein isothiocyanate combined specifically with all but 3 of 25 strains of the soybean-nodulating bacterium Rhizobium japonicum. The lectin did not bind to any of 23 other strains representative of rhizobia that do not nodulate soybeans. The evidence suggests that an interactions between legume lectins and Rhizobium cells may account for the specificity expressed between rhizobia andhost plant in the initiation of the nitrogen-fixing symbiosis. aLectina aLectin1 aSCHMIDT, E.
