ABSTRACT:
A novel approach for the increased dinitrogen fixation of leguminous plants wherein the root nodulation of the leguminous plant is controlled so as to promote nodulation by a desired bradyrhizobial strain and to inhibit nodulation of an undesired bradyrhizobial strain. Novel leguminous plant lines are provided which restrict nodulation by undesired bradyrhizobial strains while allowing nodulation of a desired bradyrhizobial strain. The plant lines are produced by conventional breeding. Recombinant bradyrhizobial strains are also provided which are characterized by a propensity for root nodulation of a predetermined leguminous plant. The recombinant bradyrhizobial strains are produced by genetic engineering.
