Figure 1From: Massive comparative genomic analysis reveals convergent evolution of specialized bacteriaPhylogenetic relationships and converging evolution. The phylogenetic unrooted tree was constructed on the basis of the 16S rRNA gene sequences from the 317 bacteria using the neighbour-joining method [15] within the Phylip package [14]. The tree was visualized using FigTree software http://tree.bio.ed.ac.uk/software/figtree/. Organisms are colored according to lifestyle: red for mutualists, purple for parasitic, green for facultative host-dependent, and blue for free-living bacteria. The events of split rRNA operons (yellow triangles) and loss of the 100 genes set (orange circles) are coincident with the location of the host-dependent bacteria in different phyla.Back to article page
