Phylogenetic tree to illustrate the evolution of the Tektin complement in nonbilaterian species. This phylogenetic analysis includes the full Tektin complements identified in six cnidarians (Aa, Che, Hv, Ad, Ep, Nv), three ctenophores (Ba, Pb, Ml), six poriferans (Oc, Em, Ha, Aq, Ht, Sc), and four bilaterians (Tc, Pd, Hs, Sk), as well as two choanoflagellates (Sr and Mo) as outgroups. Both Bayesian and Maximum Likelihood analyses were performed using Mr. Bayes and RAxML, respectively. The Bayesian tree topology is shown. Node support is shown for non-terminal nodes. Posterior probability values from Mr. Bayes and bootstrap values from RAxML are shown above or below each node, respectively. Diamonds indicate support less than 80%. “X” under a node indicates that this node was not recovered in the RAxML maximum likelihood tree. Tree was rooted with choanoflagellate sequences. Nonbilaterian Tektins fall into one of two groups: Tektin-2 and Tektin-1/4/3/5. Tektins are named according to the groups recovered by this phylogenetic analysis. Species abbreviations and accession numbers for each sequence are provided in Additional file 5
