Reclassification of four subspecies in the genus to sp. nov., sp. nov., sp. nov. and sp. nov. No Access

Abstract

The genus includes, at the time of writing, eight subspecies with validly published names. subsp. NBRC 15459 and subsp. NBRC 13045 show 16S rRNA gene sequence similarities of >99.7% to their parent species subsp. NBRC 13905 and subsp. NRRL B-2774, respectively. In contrast, the type strains of the remaining six subspecies, subsp. rubradiris and subsp. , do not show >99.0% 16S rRNA gene sequence similarity to that of each parent species. Although subsp. and subsp. were respectively reclassified to ‘’ and ‘’, these names have not been validly published yet. In this study, we investigated the taxonomic positions of subsp. , subsp. asoensis, subsp. and subsp. given that their whole genome sequences are available. Except for subsp. , these subspecies were discriminated from the parent and closely related species based on phylogenetic, genomic and phenotypic differences. Thus, we reclassify S. subsp. rubradiris and subsp. as sp. nov., sp. nov., sp. nov. and sp. nov., respectively. Multilocus sequence and 16S rRNA gene sequence analyses suggested that subsp. and subsp. may also be reclassified as independent species.
