Figure 2

Radical amino acid changes in selected sites across the catarrhine primates phylogeny of TAS1R2. The input tree used for pressure analysis of TAS1R2 is shown on the left. Positively selected sites detected by site models and branch-site models are shown on the right. Radical changes are shown in bold and underlined, and changes detected by branch-site models are marked in red additionally. Callithrix jacchus was used as outgroup, but not included in the CODEML analysis. Lineages under positive selection are marked in red, while lineages experienced relaxation of selective constraints are marked in blue.
