Figure 2.

First part of the GBDP tree shown in Figure 1, focusing on misplaced Bacteroides species, on taxa outside the phylum Bacteroidetes and on the class Saprospiria. Tip labels with gray background indicate type species of genera, colors, and symbols to the right of the tips indicate, from left to right, phylum, class, order, and family; for details and abbreviations (see Figure 1). The blue color gradient right indicates the G+C content as calculated from the genome sequences, followed by black bars indicating the (approximate) genome size in base pairs.
