16S rRNA gene amplicon sequences passing the identity threshold to the reference genomes.

<p>Percentage of amplicon sequences from three datasets passing identity cutoffs from 0.75 to 1.00 against 16S rRNA gene sequences in the genome database were depicted. Green line, human feces dataset; blue line, human oral biopsy dataset; pink line, rat feces dataset; gray line, hypersaline microbial mat dataset.
