Figure 5From: Genome wide survey of G protein-coupled receptors in Tetraodon nigroviridisPhylogenetic tree of the Tetraodon and fish odorant receptors. Tetraodon odorant receptors are in red. Bootstrap support is indicated with circle on the relevant branch point for 60 to 80% and a square for 80 to 100%. Branches of possibly orthologous grouping of odorant receptors are marked with an asterisk.Back to article page
