Abstract

Three fast-growing rhizobial strains isolated from effective nodules of common vetch ( L.) were characterized using a polyphasic approach. All three strains were assigned to the genus on the basis of the results of 16S rRNA gene sequence analysis. Phylogenetic analysis based on concatenated genes separated the strains into a distinct lineage represented by WYCCWR 11279, which showed average nucleotide identity values of 95.40 and 93.61 % with the most similar phylogenetic type strains of CCBAU 03386 and FB T, respectively. The digital DNA–DNA hybridization relatedness values between WYCCWR 11279 and the closest related type strains were less than 70 %. Therefore, a novel rhizobial species is proposed, sp. nov., and strain WYCCWR 11279 (=HAMBI 3709=LMG 31534) is designated as the type strain for the novel species.
