Figure 1From: A trypsin-like protease with apparent dual function in early Lepeophtheirus salmonis (Krøyer) developmentMaximum likelihood tree. The tree was generated by the Proml module in the Phylip package. Phylogenetic analysis of selected S1A peptidases. Support was calculated by bootstrapping (B) and quartet puzzling (P). Unsupported branches are indicated by *. Bacterial trypsin was used as outgroup. Accession numbers are indicated in the tree.Back to article page
