Figure 2
Population structure and diversity of the bacterial phylum Poribacteria based on a taxonomic query in IMNGS.
(A) Successive clustering of Poribacteria sequences (n = 2,308) at different levels of sequence similarity (~3, 5 and 10%). Prominent molecular species and genera clusters based on the number of samples they represented in the database (black bars) are written in bold and indicated by colored nodes. The star represents the candidate type species of Poribacteria originally investigated by single-cell genomics28. (B) Host specificity of sponge colonization by Poribacteria. Average contribution of each prominent molecular species of Poribacteria relative to the total number of sequences classified as Poribacteria in the different sponge species. The maximum relative sequence abundance of Poribacteria in the microbial profiles of each sponge is shown in parenthesis (the rest corresponded to other bacteria).
