Ciclid TAAR phylogenetic tree. Phylogenetic tree constructed with the cichlid TAARs (n = 117) and the model fish TAARs (n = 211). TAAR names are color-coded according to the fish species: Till in red, Bur in green, Bri in blue, Nye in orange, Zebra in purple and model fish TAARs in black. The percentage of identity shared by each adjacent gene pair was calculated with CLUSTAL W [51] and thresholds of 40% and 60% were used to define families and sub-families (see Methods section). Families are designated by letters (A to F) and sub-families by numbers (1 – 7). Classes I, II and III, as defined by Hussain et al. [16] are indicated. Gains and losses of introns are indicated at the roots of family A and subfamilies 5 and 6, respectively. The out group made of 38 class A nonTAAR GPCRs is at the bottom of the tree. Number above branches are bootstrap values based on 1,000 replicates, Values below 50% are not shown. The scalebar represents the average number of nucleotide substitutions per site.
