Phylogenetic analyses of Noto15 and Noto9 duplicates found in Oikopleura. Phylogenetic reconstructions performed for (A) Noto15 and (B) Noto9 (Far UpStream Element Binding Proteins, or FUSEBPs) duplicates found in Oikopleura. Trees were obtained from neighbor-joining analyses and rooted using heterogeneous nuclear ribonucleoprotein K (HNRNPK) and Rho-like and Ran protein sequences, respectively, as outgroups. Statistical support values ≥80% obtained with different methods are included over conserved nodes; the first number indicates the bootstrap support in neighbor-joining analysis (1000 bootstrap replicates), the second number reports the posterior probabilities in Bayesian inference analysis. Note that a single value of 54% posterior probability was kept on the node grouping all tunicate Noto15 orthologs. Abbreviations: Ci: Ciona intestinalis; Cs: Ciona savignyi; Mt: Molgula tectiformis; Hr: Halocynthia roretzi; Dl: Diplosoma listerianum; Od: Oikopleura dioica; Bf: Branchiostoma floridae; Hs: Homo sapiens; Mm: Mus musculus; Pm: Petromyzon marinus; Sk: Saccoglossus kowalevskii; Sp: Strongylocentrotus purpuratus; Pl: Paracentrotus lividus. The scale bars indicate the branch length that corresponds to the number of substitutions per residue.
