Coexisting lineages display similarities in genomic features. Here, we exclusively focus on co-occurring lineages for which completely sequenced genomes could be mapped to both partners (this genome mapping is globally visualized in Supplemental Fig. S6). Properties of such co-occurring genomes are compared, and contrasted against randomly paired genomes. (A) The distribution of 16S sequence divergence scores; shifted to the left for co-occurring genome pairs (i.e. they tend to be related phylogenetically). In panels E, F, and G, we test for independence between phylogenetic relatedness, and observations as shown in panels B, C, and D, respectively. Here, each dot denotes a pairwise genome comparison, and lines correspond to running medians.
