FIGURE 2.

Edited radial phylogenetic tree of the chordate deduced full-length CRH-family precursors. Tree was constructed with the Bayesian inference (BI) and the complete tree is available in Supplementary Figure S2. The maximum likelihood (ML) tree is available in Supplementary Figure S4 and branch support values (BI posterior probability and ML bootstrap values) are shown only for the two major peptide subfamily clades. Accession numbers of the sequences used are available in Supplementary Table S2.
