Cladograms Cg-defs and Cg-prp and schematic representation of aligned CDS with synonymous and nonsynonymous substitutions. a. Cg-defs. b. Cg-prp. Identical sequences are grouped and the number is indicated at the right of each branch of cladograms and sequence symbols are the same as in figure 1. Nonsynonymous (blue boxes) and synonymous substitutions (yellow boxes) are localized over schematic alignment. Different groups of sequences (I, II and III) and obvious recombinants (R) are boxed. Indel events are represented by dark lines (Cg-prp) and striped box (Cg-defs) and circles indicate parallel homoplasic mutations. SP: signal peptide; MP: Mature peptide; AD: Anionic Domain; CD: Cationic Domain. For accurate comparison between AMPs, cladograms were drawn in the same scale.
