Bubble Plot from Scientific Research

Relative abundance of genomes encoding C1 pathways across metagenomic samples. Bubble size indicates the combined coverage of all organisms encoding a given pathway in each sample normalized by the total coverage of all genomes in the quality-filtered, non-redundant set. The dashed box around methane production indicates the data points expanded in part b), showing the relative abundance (again, as indicated by percent of total genome coverage) for organisms from methanogenic lineages, with and without mcr genes. Abbreviations: CO, carbon monoxide; TCA, tricarboxylic acid cycle; anox., anoxic zone; sed., sediment; mcr, methyl-coenzyme M reductase
