(Primulaceae), at the the State Natural Reserve ‘Belogorie’, Russia. On the basis of 16S rRNA gene sequence comparisons, the strain clustered with members of the genus Rathayibacter , showing the highest sequence similarity to Rathayibacter tritici (98.89 %), Rathayibacter rathayi (98.82 %) and Rathayibacter festucae (98.82 %). The DNA hybridization experiments demonstrated that strain DL-329T represents a separate genomic species. The results of comparative studies of physiological and chemotaxonomic characteristics, including cell-wall sugar patterns, polar lipid profiles, and the matrix-assisted laser desorption/ionization time-of-flight mass spectra of bacterial cells, allowed clear differentiation of VKM Ac-2121T from the recognized Rathayibacter species at the phenotypic level. Based on the data obtained, a new species, Rathayibacter oskolensis sp. nov., is proposed, with DL-329T (=VKM Ac-2121T=LMG 22542T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002681
