FIG 2.

Habitat-based groupings of marinimicrobial genomes and their genomic features. (a) Heat map showing the abundance of marinimicrobial genomes in clades 1 to 7 in different metagenomic samples, with both samples and habitat groups color coded. Note that the abundance values here are the same as those presented in Fig. 1c (units of log₁₀ TPM). (b) Dot plots showing the genomic features of Marinimicrobia genomes between habitat groups (orange, epipelagic; purple, mesopelagic). Each dot represents a genome, and boxes indicate the means and standard errors. Asterisks denote significant differences between epipelagic and mesopelagic genomes (**, P  < 0.01; *, P  < 0.05). The “All” category includes all genomes in clades 1 to 7 that could be assigned to a habitat group, while categories C1, C2, C5, C6, and C7 show only the genomes corresponding to those clades. Clades 3 and 4 are not shown since they did not include multiple genomes in both habitat groups.
