Schematic view of poribacterial BMC shell protein groups.

<p>For a better overview all genes are displayed in 5′-3′ direction of the BMC shell protein gene. The actual strand orientation might be different and is indicated by plus or minus signs. Genes are shown with locus taq and amino acid identities based on IMG/MER homology searches are shown between genes where applicable. BMC shell protein genes are shown in white, other genes with homologies between different SAGs are shown in dark grey, other genes are shown in light grey.</p

16S rRNA gene based maximum likelihood tree illustrating the phylogenetic position of the candidate phylum <i>Poribacteria</i>.

<p>Bootstrap values (500 resamplings) ≥50% are shown on tree nodes. Numbers of sequences included per group is shown in group boxes. Outgroup consists of 80 sequences belonging to the <i>Bacteroidetes</i>. Scale bar represents 10% sequences divergence.</p

Phylogenomic tree based on a concatenated alignment of up to 83 genes illustrating the phylogenetic position of the candidate phylum <i>Poribacteria</i>.

<p>Bootstrap value (100 resamplings) are shown on tree nodes where support ≥50%. Number of genomes per group is displayed in group boxes. Outgroup consists of several species of <i>Spirochaetes</i> and <i>Gammaproteobacteria</i>. The scale bar represents 10% sequence divergence.</p
