Abstract

Symbiotic bacteria belonging to the genus Bradyrhizobium were generally called ‘rhizobia’ which can fix nitrogen by nodulating legumes. Between 2000 and 2001, numerous Bradyrhizobium strains were isolated from root nodules. However, due to challenges in identification, many of these isolates remained unreported. Recent advances in phylogenetic analyses based on whole genome sequencing have resolved these difficulties in species identification. Consequently, five of these strains have now been re-identified and are described as previously unrecorded species in the Republic of Korea. As a result, we report Bradyrhizobium elkanii Glm-3 (=KACC 10989), Bradyrhizobium australafricanum Glm-4 (=KACC 10990), Bradyrhizobium huanghuaihaiense Glm-7 (=KACC 10993), these were isolated from root nodules of Glycine max, Bradyrhizobium frederickii Kus-5 (=KACC 11016) isolated from root nodules of Kummerowia striata and Bradyrhizobium diazoefficiens Leb-14 (=KACC 11026) isolated from root nodules of Lespedeza bicolor.
