Phylogenetic relationship amongst the putative GULO orthologs identified in Protostomian and non-Bilaterian species that have a HWAK motif. Two Fungi GULO CDS were used to assist rooting of the consensus tree (red pane). GULO CDS of six deuterostomian species, representing the Actinopteri, Amphibia, Euarchontoglires, Aves, Reptilia and Cephalochordata groups, were used to facilitate the identification of functional GULO orthologs among Animal species (green pane). Higher taxonomic classifications for common species are shown on the right
