Figure 5From: Unprecedented loss of ammonia assimilation capability in a urease-encoding bacterial mutualistGene loss and erosion in Blochmannia. The differential gene content of the three Blochmannia genomes is shown in a phylogenetic context to highlight small frameshifts and missing or eroded genes. Presence of a gene is shown with a plus sign and absence of a gene with a zero. Pseudogenes are indicated by a psi symbol (ψ), and frameshifts are denoted with the letter f. COG functional categories are shown on the bottom line. Genes for which frameshifts, erosion, or loss occur independently in different Blochmannia lineages are marked in boldface.Back to article page
