From: Positive selection on the K domain of the AGAMOUS protein in the Zingiberales suggests a mechanism for the evolution of androecial morphology

Figure 5

Selection test results. (A) PAML branch selection test. Omega (w) values are depicted for each branch in the gene tree. A likelihood ratio test (LTR) for branch models (M1a and M2a) was performed. PAML detects a strong selection signal at the base of the Zingiberales sequences, but nowhere else in the gene tree. (B) HyPhy (package FEL) site selection test. Tree shows nodes (in red) tested for positive selection. Balancing and positive selected residues are marked along the AGAMOUS protein domains. As expected, FEL detected various sites under balancing selection, while three sites were detected to be under positive selection, particularly in the I and K domains. Table shows selection test statistics for all positive selected sites observed in the analysis.
