Maximum likelihood tree of manganese/iron-containing SODs (MnFeSODs) derived from a 195 amino acid alignment of sequences from selected species. Accession numbers for each sequence are in parentheses. Sequences for N. vectensis and C. teleta are from respective genomic databases at the Joint Genome Institute. The sequences for Acropora digitifera are from the genomic database at the Okinawa Institute of Science and Technology. All other sequences are from NCBI. The tree was rooted with sequences from prokaryotes. Values above nodes indicate percentage of 1000 bootstraps. Bootstrap values below 40 were removed. Circles indicate posterior probabilities from Bayesian analysis for shared clades between analyses.
