Fig. 2: Mean coverage, used here as a proxy for relative abundance, of AOA MAGs in the samples they were reconstructed from.

The size of the points is proportional to the mean coverage of the considered MAG in a given sample. Mean coverage was set to 0 in samples where detection (or breadth of coverage) was below 0.7. Bubbles are colored according to geochemical zonation of the sample (characterized in Schauberger et al. [27]). Samples are grouped by site and replicate core when appropriate (color code on the right-hand side of the figure), and ordered vertically by increasing horizon depth. The top panel represents the ML phylogenomic tree of the reconstructed MAGs generated using GTDB toolkit and IQTREE, with amoA clades colored according to Alves et al. [10] and the results from Fig. 1.
