jezb22531-sm-0001-SupFig-S1.tif111932KFigure S1. Phylogenetic tree of the OR genes with all gene names and bootstrap values. The tree was constructed using Maximum Likelihood (ML) and an LG substitution model as the best fit for the protein dataset. Six non-OR GPCR genes were used as outgroup (black). Blue = zebrafish ORs, green = human ORs, red = coelacanth ORs.
jezb22531-sm-0001-SupFig-S2.tif25497KFigure S2. Conservation of amino acids in the 15 putative L. chalumnae V1Rs as compared to conserved amino acids in the ORAs of teleost fish (Saraiva and Korsching, 2007) and V1Rs in mouse (Pfister and Rodriguez, 2005). The sequence logo was constructed using WebLogo (Crooks et al., 2004).
jezb22531-sm-0001-SupFig-S3.tif15105KFigure S3. Phylogenetic tree of the V1R/ORA genes including five putative lamprey ORAs. The tree was constructed using Maximum Likelihood (ML) and a JTT substitution model as the best fit for the protein dataset. Zebrafish T2Rs served as outgroup (black). Gray = sea lamprey ORAs, violet = elephant shark ORAs; blue = teleost ORAs (zebrafish), green = tetrapod V1Rs (frog, lizard, human), red = coelacanth V1Rs.
