Fig. 3: 16 rRNA gene phylogeny and abundance in metagenome and amplicon data.

Phylogeny of 284 16S rRNA genes reconstructed from the metagenomic data. From inside to outside the concentric circles around the phylogenetic tree indicate: the taxonomy of the major clades in the phylogeny, as assigned by Silva138, the recovery of the sequence through phyloFlash and/or annotation of the retrieved MAGs, the abundance in the surface (0–7 cm) and deep (7+ cm) section of the cores used for metagenomic sequencing, the abundance in the surface (0–7 cm) and deep (7+ cm) sections of the cores retrieved from Z-vent through amplicon sequencing, and the abundance in the shallow (0–7 cm) and deep (7+ cm) sections of the cores retrieved from Diane’s vent through amplicon sequencing. Circled numbers highlight abundant taxa discussed in the main text.
