Fig. 3

Relative abundance of ASVs classified at species level. The left panel shows results for the GTDB database and the right panel shows results for the Silva database. For each database, full-length and V4-V5 16S rRNA gene sequencing were compared (orange and blue, respectively). Only ASVs with more than 0.1% relative abundance, per sample, were illustrated. The Log10 scale was used to allow the distinction between ASVs with less than 1% relative abundance. All species derived from MAGs in the GTDB classification, but without a binomial species name, were grouped in the category “GTDB placeholder”. Phylum, order, and genus level information is provided for each species listed
