Figure 4. The phylogenetic relationship of the signatures containing the Cys-rich domain CRYWCKTPEGQAYCC was inferred using the Maximum Parsimony method, and the bootstrap consensus tree inferred from 1,000 replicates is shown.

The sequences of six species of penaeids distributed along the American coasts are located in a clade. Sequences from P. japonicus and P. monodon were pooled. The non-condensed tree is found in Table S5.
