Bayesian tree showing the phylogenetic relationships between metazoan COE/EBF proteins. Squared numbers indicate the statistical supports supporting the corresponding nodes : top line, posterior probabilities (x100) in BI, second and third lines, bootstrap proportion (%) obtained in ML and NJ analyses respectively. The statistical supports are only shown for the monophyletic groups obtained in all three reconstruction methods used (protostomes, lophotrochozoans, vertebrates, COE1, COE2, COE3 and EBF4). Those obtained inside the four vertebrate monophyletic groups were omitted for sake of clarity. The tree was rooted using the N. vectensis sequence (squared). Species abbreviations : Mm, Mus musculus (mouse); Hs, Homo sapiens ; Md, Monodelphis domestica (opossum); Xt, Xenopus tropicalis ; Dr, Danio rerio (zebra fish) ; Pm, Petromyzon marinus ; Bf, Branchiostoma floridae ; Dm, Drosophila melanogaster ; Lg, Lottia gigantae (mollusc) ; Cc, Capitela capitata (annelid) ; Nv, Nematostella vectensis (sea anemone). The scale bar represents the number of substitutions per amino-acid along each branch. Accession numbers are indicated in table S1.
