RT Journal Article SR Electronic(1) A1 Sakamoto, Mitsuo A1 Ohkuma, MoriyaYR 2012 T1 Reclassification of Xylanibacter oryzae Ueki et al. 2006 as Prevotella oryzae comb. nov., with an emended description of the genus Prevotella JF International Journal of Systematic and Evolutionary Microbiology, VO 62 IS Pt_11 SP 2637 OP 2642 DO https://doi.org/10.1099/ijs.0.038638-0 PB Microbiology Society, SN 1466-5034, AB 16S rRNA gene sequence information has indicated that Xylanibacter oryzae has a close relationship with the genus Prevotella . To clarify the taxonomic position of X. oryzae , we determined the sequence of hsp60 as it represents an alternative phylogenetic marker for identification and classification of Gram-negative anaerobic rods. On the basis of hsp60 sequences, X. oryzae was located within the genus Prevotella , indicating that the species does not represent a distinct taxon at the genus level. Statistical tests (the Shimodaira–Hasegawa test and the approximately unbiased test) supported the finding that X. oryzae is monophyletic with members of the genus Prevotella and thus belongs to the genus. On the basis of the phylogenetic findings, we propose that X. oryzae should be reclassified as Prevotella oryzae comb. nov.; the type strain is KB3T ( = JCM 13648T  = DSM 17970T). An emended description of the genus Prevotella is also provided., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.038638-0
