Extended Data Figure 4: Cichlid OR and TAAR genes.
From: The genomic substrate for adaptive radiation in African cichlid fish
a, Cichlid OR and TAAR genes identified in this study. b, PHYML tree based on the fish TAAR and OR amino acid sequences. A phylogeny tree was constructed with all OR and TAAR cichlid proteins identified in this study (n = 503 + 119) plus 229 OR and 173 TAAR genes identified in zebrafish, fugu, tetraodon, medaka and stickleback. The amino-acid sequences were aligned with MAFFT version 7 and a tree constructed with PHYML and visualized with Fig Tree (version 1.3.1). The TAAR branches are in pink and the OR branches in blue or yellow. Colours indicate the composition of the branches. Dark blue branches are made of cichlid OR only, light blue indicates the presence of cichlid and model fish OR proteins. Yellow is for branches made of OR model fish proteins, only. Light pink branches correspond to cichlid and model fish TAAR proteins and dark pink to model fish TAAR proteins only. Letters correspond to family names.
