Genomic variation between Ca. Chlorobium antarcticum populations from AL, EF, and TB. Circos plot depicts read depth distribution of Ca. Chlorobium antarcticum in the oxic-anoxic interface of AL (Dec 2014), EF, and TB. The mean read depth of the EF_ref MAG in each merged metagenome (Additional file 1: Table S14) is shown at the beginning of each annulus (top). Outer to inner annuli and their y-axis range: EF_ref MAG contigs E1–E32 (
); Dec 2014 (
, 0–10,000); EF 45m (
, 0–15,000); TB 11m (
, 0–800); EF_ref MAG genes containing SNPs in AL (
), TB (
), or both (
), with connecting lines indicating gene position. The x-axis is shown on the outermost annulus: beginning of each contig, red tick; 10-kb length, grey tick; LCRs, labelled 1–12, with LCR1–7 as for AL_ref MAG (Fig. 4). Scaffolds were represented by contigs: E1–7, E8–12, E13, E14–16, E17–18, E19, E20, E21–22, E23–24, E25, E26, E27, E28, E29, E30, E31, and E32 (see MAG contigs ordering in the “Methods” section; Additional file 1: Table S3)
