N2 - Three slow-growing rhizobial strains (WYCCWR 12678, WYCCWR 12774 and WYCCWR 13023T) isolated from effective nodules of Arachis hypogaea L. (cultivated peanut) sampled in Zhengyang County, Henan Province, central China were characterized using a polyphasic approach. The three strains were assigned to the genus Bradyrhizobium based on phylogenetic analysis of their 16S rRNA sequences. Phylogenetic analysis based on their concatenated recA-glnII-gyrB-dnaK-rpoB gene sequences placed the strains into a distinct lineage. Whole-genome average nucleotide identity (ANI) values between WYCCWR 13023T and WYCCWR 12774 and WYCCWR 12678 were 99.43 and 99.31% respectively. ANI values between WYCCWR 13023T and the most closely related strains were all below 93%. The digital DNA–DNA hybridization (dDDH) values between WYCCWR 13023T and ‘B. guang-zhouense’ CCBAU 51670T, B. manausense BR 3351T and B. guangdongense CCBAU 51649T, the three most closely related type strains, were 50.40, 43.50 and 39.20% respectively. Phenotypic characterization also allowed the differentiation of the novel strains from their most closely related type strains. Based on the genotypic and phenotypic features, we conclude that the three strains represent a novel species for which the name Bradyrhizobium zhengyangense sp. nov. is proposed, with WYCCWR 13023T (=GDMCC 1.3180T=HAMBI 3760T) as the type strain.
