Overview of the prokaryotic genomes. The phylogenetic tree contains 14,727 genomes with tips colored according to their phylum classification. Rings: (1) Phylum classification of the genomes. Phyla with less than 5 genomes are in the “Others” category. (2) Completion status of the genomes with black for finished genomes and white for draft genomes. (3) Number of contigs in each genome. (4) Number of proteins in each genome. (5) Percentage of proteins annotated by UniFam in each genome. (6) Number of pathways inferred for each genome.
