Fig 1. Phylogenetic analysis of cocoonase homologs.

The phylogenetic tree was constructed using the Maximum Likelihood method, based on the Poisson correction model with 1,000 bootstrap replicates, and bootstrap support values more than 50% were shown in the tree. The 295 cocoonase homologs from 12 classes, identified with different colored fonts, are divided into 14 clades, showed in the outer ring. And 70 protein sequences from the Lepidoptera were aggregated with the clade containing silkworm cocoonase, shown in the orange curved area.
