Fig. 8From: Expansion of cytochrome P450 and cathepsin genes in the generalist herbivore brown marmorated stink bugPhylogenetic analysis of cathepsins in Halyomorpha halys. A phylogenetic tree generated using cathepsins (Cathepsin-B and Cathepsin-L) in H. halys along with corresponding cathepsins in other insects is shown. The evolutionary history was inferred by using the Maximum Likelihood method based on the Whelan and Goldman model. All nodes have significant bootstrap support based on 1000 replicates. The bootstrap values only above 50% are shown next to branches. The asterisks indicate the locations of H. halys cathepsin-L gene expansion. GenBank accession numbers for various protein sequences used in the phylogenetic analysis are provided in Additional file 2Back to article page
