Alignments of amino acids sequences of putative isoforms for Cg-defs and Cg-prp from C. gigas. a. Cg-Defm (FJ669323-FJ669336) and Cg-defhs (FJ669341- FJ669352). b. Cg-Prp (FJ669354- FJ669402). Highlighted sites showed evidence of positive (in black) or negative (in gray) selection (p < 0.05). Dots indicate identical residues and gaps (-) were introduced to obtain maximum sequence identity. The different domains are indicated in white boxes at the bottom of alignments.
