    Abstract: Methods for the isolation of mutant rhizobial strains with improved competition of nodulation (Comp.sup.+) is presented. Mutants are selected for constitutive expression of inducible nod genes (in the absence of inducer) and screened for hyperinduction of nod genes in the presence of inducer. Mutants which are defective in nodulation or in symbiotic nitrogen fixation are eliminated from further testing. Selections for constitutive nod expression and for hyperinduction of nod genes are facilitated by the use of plasmid carrying a selectable marker fused to an inducible nod gene and a plasmid carrying a reporter gene fused downstream of an inducible nod gene. The methods exemplified are particularly useful for the isolation and identification of Comp.sup.+ mutants of Bradyrhizobium japonicum.

    Abstract: A symbiosis plasmid from a fast-growing Rhizobium japonicum donor strain can be transferred to Rhizobium recipient strains, the recipient strains being previously incapable of forming an effective symbiotic relationship with plants of certain Glycine (e.g. soybean) varieties. The recipient strains harboring the symbiosis plasmid will form effective symbioses with soybean plants of said certain varieties, the transferred symbiosis plasmid conferring the host range or specificity of the donor strain on the recipient strains. Methods, strains, and plasmids useful for practice of this invention are also provided.

    Abstract: The isolation and characterization of nodD-related genes in soybean nodulating Rhizobium japonicum is described. In R. japonicum USDA 191 two such genes have been identified, which although related in structure, have different functional properties. These nodD genes are functionally distinct from each other and from those nodD genes of other strains of Rhizobium that have been isolated and characterized to date. In particular, nodD-r1 has been found to affect nodulation on soybean and to be associated with exopolysaccharide production. In contrast, nodD-r2 affects nodulation on the tropical legume siratro. The coding sequences of both nodD genes are provided. The promoter regions of the nodD genes have also been isolated. The genes described herein, including both structural genes and their promoter regions, can be used in combination with other genetic constructs to enhance the efficiency and competitiveness of nodulation.

    Abstract: The chemical compounds that induce expression of nodulation genes of Bradyrhizobium japonicum strains have been identified. The isoflavones daidzein and genistein were identified as soybean exudate components that induce nod-genes. Other isoflavones, including 7-hydroxyisoflavone, 5,7-dihydroxyisoflavone, biochanin A, formononetin and prunetin, were also found to act as inducers. In addition, several flavonoid compounds including 4',7-dihydroxyflavone, apigenin, kaempferol and coumestrol, were also found to act as inducers. Nodulation inducing compositions and a method for selectively activating the expression of a gene under the control of a soybean exudate inducible promoter in B. japonicum in response to these inducer molecules are described. In addition, soybean inoculating compositions containing the nod-gene inducers and inoculating methods employing these compositions are described.
