Fig. 3From: Genome-wide identification and expression profiling of serine proteases and homologs in the diamondback moth, Plutella xylostella (L.)Phylogenetic relationship of chymotrypsins in P. xylostella and other Lepidoptera species. The phylogenetic tree was constructed using MEGA 6.06 with neighbor joining approach based on Poisson model and pairwise deletion of gaps. The percentage bootstrap scores higher than 50Â % are indicated on the nodes. The first two letters in each of the gene names represent the acronym of scientific name for a given species (Px: Plutella xylostella; On: Ostrinia nubilalis; Ha: Helicoverpa armigera; Bm: Bombyx mori). P. xylostella chymotrypsins are marked with red dotsBack to article page
