FIGURE 5

Simplified phylogeny of bivalve big defensins, exemplified by variants found in the genomes and transcriptomes of the oyster Crassostrea gigas (Cg-BigDefs), the mussel Mytilus galloprovincialis (Mg-BigDefs), the clam Dreissena rostriformis (Dr-BigDefs and (Dr-ncBigDefs) and the four scallop species Pecten maximus (Pm-BigDef), Mizuhopecten yessoensis (My-BigDef), Argopecten purpuratus (Ap-BigDef1) and Argopecten irradians (Ai-BigDef). The tree was obtained through Bayesian inference using MrBayes v3.2.1, with two parallel MCMC analyses run for 500, 000 generations each, based on a VT + G model of molecular evolution. For simplicity’s sake, variants sharing >90% pairwise identity have been removed. The tree was rooted on D. rostriformis, as the only member of the superorder Imparidentia. Posterior probability support values are shown for each node.
