Chloroflexi diversity and abundance from the Rifle sediment metagenomes. Left: Maximum likelihood phylogeny of the Chloroflexi phylum based on an RpS3 protein alignment. Bootstrap values >50 are displayed, with bootstraps >95% denoted by a black circle. Rifle-derived RpS3 sequences are marked with red stars, complete genomes with filled squares, and environmental sequences mined from NCBI and IMG/M with empty circles. See Methods for alignment and phylogeny details, and Additional file 1: Figure S1 in the supplemental online material for full sequence names. Right: Stacked bar charts of normalized coverage values for each rpS3-containing scaffold in each depth’s metagenome.
