Abstract: We isolated 18 rhizobial strains from root nodules of a leguminous shrub Laburnum anagyroides (common laburnum) grown in Southeast Poland as an exotic plant. With the use of BOX-PCR fingerprinting, the isolates were clustered into 2 main groups and one separate lineage, which was congruent with the ITS-RFLP results. The phylogenetic trees constructed based on 16S rRNA and combined atpD, dnaK, glnA, and recA gene sequence data separated the representative strains into three evolutionary lineages within the Bradyrhizobium jicamae supergroup, with Bradyrhizobium algeriense and Bradyrhizobium valentinum as the closest relatives. The nodA and nifH gene phylogenies proved that the L. anagyroides symbionts carry a symbiotic gene variant known as Clade IV, representing the symbiovar retamae. Phenotypic characteristics of the isolates and reference strains are also reported. Our study of the rhizobia nodulating L. anagyroides growing in Poland complements earlier few findings on the symbiotic associations of this Genisteae species.
