Figure 3

Phylogenetic tree of SAL1 family. The phylogenetic tree was reconstructed using maximum likelihood (ML) and rooted by midpoint rooting. Bootstrap values are given for main branches, in bold when nodes are strongly supported (>80%). The 50 mammalian SAL1 amino-acid sequences related to the 50 identified functional genes were used to reconstruct the phylogenetic tree. After removal of gaps, the dataset comprised 119 sites. Blue circles represent speciation and red squares duplication. Branches on the tree that were tested for positive selection on species clades are indicated by black arrows.
