Figure 2.

Phylogeny of mitochondrial transcription factors and small-subunit rRNA dimethylases. Bayesian phylogenetic analysis from conserved amino acid sequence sections indicated in the amino acid sequence alignment (see Figure S1). Collapsed branches of orthologous and paralogous proteins from the detailed phylogenetic tree (see Figure S2) are displayed as triangles. Total branch length to the closest and the farthest leaf are used to calculate the length of the triangles.
