Abstract

In this study, we present the complete genome of Fimbriimonas ginsengisoli Gsoil 348T belonging to the class Fimbriimonadia of the phylum Armatimonadetes, formerly called as candidate phylum OP10. The complete genome contains a single circular chromosome of 5.23 Mb including a 45.5 kb prophage. Of the 4820 open reading frames (ORFs), 3,000 (62.2%) genes could be classified into Clusters of Orthologous Groups (COG) families. With the split of rRNA genes, strain Gsoil 348T had no typical 16S-23S-5S ribosomal RNA operon. In this genome, the GC skew inversion which was usually observed in archaea was found. The predicted gene functions suggest that the organism lacks the ability to synthesize histidine, and the TCA cycle is incomplete. Phylogenetic analyses based on ribosomal proteins indicated that strain Gsoil 348T represents a deeply branching lineage of sufficient divergence with other phyla, but also strongly involved in superphylum Terrabacteria.
