In Rhizobium phaseoli strain 8002, a large indigenous plasmid, pRP2JI, had previously been shown to carry many of the genes necessary for the induction of nitrogen-fixing nodules on Phaseolus beans. A cosmid clone library was constructed using DNA from strain 8002. From this library, two overlapping recombinant plasmids (pIJ1097 and pIJ1098) were isolated which spanned about 43 kb of pRP2JI DNA. These plasmids could restore nodulation to some, but not all nodulation-deficient strains of R. phaseoli, indicating that the nodulation genes were not clustered within one small region of pRP2JI. The cloned R. phaseoli nodulation region shared extensive DNA homology with the nodulation genes of R. leguminosarum, and on the basis of DNA hybridization, the nitrogenase genes were found to be within 10 kb of the R. phaseoli nodulation genes. Close to the nodulation genes of R. phaseoli was located a sequence that was repeated on pRP2JI but which was not present elsewhere in the genome of strain 8002.
