Metabolic and functional repertoire of the high quality Patescibacteria MAGs. The heatmap shows completeness of pathways and presence/absence of the functions in 291 high-quality Patescibacteria genomes annotated within DRAM [72], arranged according to their phylogenetic placement. Clade background colors within the phylogenetic tree represent respective taxonomic classes of Patescibacteria. Colored triangles next to each genome represent their enrichment in 0.1 µm filter fractions (green), 0.2 µm filter fractions (red), anoxic wells (blue) and oxic wells (orange), respectively. Electron transport chain complexes I–IV, sulfur metabolism functions, and photosynthesis related genes were absent from almost all the MAGs. A similar heatmap arranged as per the fivefold enrichment of the MAGs in oxic and anoxic wells is provided as Additional file 5: Fig. S2
