Figure 2. Mammalian OR family structure.

Figure 2

Maximum likelihood tree obtained with Tamura-Nei substitution model (1000 bootstrap) using representative sequences of all OR Families from the available Mammalian database [22], together with the Bathyergidae OR genes characterised in this study. OR families are colour-coded as reported on the right. All Bathyergidae ORs appear to cluster together with mammalian Family 7 OR genes (indicated in green, together with the bootstrap support value for that branch).
