Phylogenetic tree containing cathepsin B- and cathepsin L-like proteins from six hemipteran species. Protein sequences of cathepsin B- and cathepsin L-like proteins from N. lugens (Nl), L. striatellus (Ls), N. cincticeps (Nc), A. pisim (Ap), H. halys (Hh) and E. onukii (EMo) were aligned and used for the phylogenetic analysis through the maximum likelihood strategy. Cathepsin D-like proteins of N. lugens and L. striatellus were clustered as the outgroup. Information regarding the proteins is shown in Files S3 and S6. Proteins from E. onukii are indicated in bold. Proteins in the phylogenetic tree mentioned in the paper are arrowed. The clade highlighted by pink and yellow contains cathepsin B- and cathepsin L-like proteins, respectively. Relative expression level is presented by log₂FC (gut vs SG) and shown by a colored circle outside the tree, from green (log₂FC = −3) to red (log₂FC = 11). Proteins with no log₂FC of FPKM are left blank
