Phylogenies from CDS of three antimicrobial effectors and non immune gene from C. gigas. a. Cg-defs: I. Cg-defh1 (black triangles); II. Cg-defh2 (white triangles) and III. Cg-defm (dark gray triangles). Recombinant sequences between Cg-defh1 and Cg-defh2 are indicated (light gray triangles). b. Cg-prp: I. Cg-prp short forms (black circles), II. Cg-prp short and long forms, and III. Cg-prp long forms (white circles). Cg-prp recombinant sequences are indicated (gray circles). c. Cg-bpi (white rhombus) and d. Cg-actin (white squares). Construction of cladograms were performed with PHYML v2.4.4 using the models GTR+Γ for Cg-defs, HKY85+Γ for Cg-prp, TN93+I for Cg-bpi and F84+Γ for Cg-actin determined by the Akaike information criterion. For accurate comparison between the four genes, cladograms were drawn in the same scale.
