Phylogenetic delineation of the novel Phylum armatimonadetes (former candidate division OP10) and definition of two novel candidate divisions

Abstract

Small-subunit (SSU) rRNA gene sequences associated with the phylum Armatimonadetes were analyzed using multiple phylogenetic methods, clarifying both the phylum boundary and the affiliation of previously ambiguous groupings. Here we define the Armatimonadetes as 10 class-level groups and reclassify two previously associated groups as candidate divisions WS1 and FBP. © 2013, American Society for Microbiology.
