Comparative genomics of Bradyrhizobia toward uncovering relationshipbetween the genetic elements and the biological effects in soybean symbiosis

The nucleotide sequences of the genomes of four Bradyrhizobial strains were determined.Comparison of their genome structures, especially constitution of the genomic islands,was explored based on the genomic information. A significantly high level of sequenceconservation was detected in symbiosis islands on USDA110 and USDA6 genomes. Diversityof the symbiosis islands of B.japonicum and B.elkanii represented some differentsymbiotic aspects between them.
