Cloning, Expression, and Characterization of Prophenoloxidases from Asian Corn Borer, Ostrinia furnacalis (Gunée)

Figure 4

Phylogenetic analysis of O. furnacalis PPOs with other homologs. The used amino acid sequences of 108 PPOs were from 34 insect species and 18 crustacean species. The names of PPO genes were shown as scientific name of species followed by NCBI accession number of the gene. The O. furnacalis PPOs are marked in red. The branches specific for coleopteran, hymenopteran, dipteran, lepidopteran, and crustacean PPOs, respectively, are shaded in squares. Numbers at the nodes are bootstrap values as percentage. The circled bootstrap values indicate that the used insect PPOs were divided into three clades.
