Figure 3:

(A) Gene family assigned with OrthoMCL for the total set of proteins predicted from 5 mussel genome projects. Outside the Venn diagram, the species name is represented, and below it is the number of proteins/number of clustered proteins/number of clusters. (B) Phylogeny of the concatenated dataset using 44 single-copy orthologs extracted from 10 molluscan genomes. The VT model was estimated to be the best-fitting substitution model with ProtTest 3.4.2. We reconstructed the phylogeny using PhyML and 100 bootstrap repetition.
