From: Tetrapod V1R-like ora genes in an early-diverging ray-finned fish species: the canonical six ora gene repertoire of teleost fish resulted from gene loss in a larger ancestral repertoire

Phylogenetic tree of ORAs. Species are indicated by the initials of their Latin names, see TableĀ 1 for full names. T2R receptors (not shown) were used as outgroup. Numbers indicate branch support. Magenta circles, ancestral genes for ora7-8b (spotted gar, Lo) and v1r07-10 (coelacanth, Lc). Scale bar, number of amino acid substitutions per site
