Description of ‘’ phyl. nov. and emended description of the phylum ‘’ and of the family , phylum ‘’ Free

Abstract

The number of bacterial phyla has greatly increased in the past decade. Among them, a candidate division named ‘’ was proposed in a phylogenetic study on the global diversity of bacteria. We previously described the genus and suggested that it belonged to this not yet well-delineated candidate phylum. 16S rRNA gene based-phylogeny studies were conducted using four reconstruction methods and 599 sequences forming five datasets were used in an alternative treeing approach. These analyses indicated that the genera , , , , , , , and should be grouped in the same high-level taxon. This taxon was shown to be a phylum-rank lineage in the domain and, because of the prior use of the name for a genus, the name ‘’ is proposed for this candidate phylum. We also propose an emended delineation of the phylum ‘’, which is now only represented by the family . The emended family is limited to the genera , , and .
