Fig. 6.

PPOX/HemY phylogenetic tree. The tree shown is the consensus tree obtained with Phylobayes 4.1 with ML boostrap values (left) and Bayesian posterior probabilities (right) mapped onto the nodes. Bootstrap values >50 % are shown, while only posterior probabilities >0.6 are shown. The tree is rooted with the distant group composed of Firmicutes, Planctomycetes and Lentisphaerae. Sequences are color-coded as follows: Amoebozoa are in purple, Euglenozoa are in blue, other eukaryotes are black, and Bacteria are brown. Eutreptiella gymnastica, Euglena gracilis, Paraphysomonas bandaisensis (all plastid-bearing organisms) and Perkinsela spp. sequences occupy distinct positions in the tree relative to other eukaryotes and bacterial homologs. The scale bar shows the inferred number of amino acid substitutions per site
