Phylogenetic tree containing serine protease-like proteins from six hemipteran species. Protein sequences annotated by trypsin, chymotrypsin and elastase 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. 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. Clades highlighted by blue and orange indicate two clusters of serine protease. The branch highlighted by red indicates a cluster of serine protease showing relatively higher FPKMs in the salivary gland than in the gut. Relative expression level is presented by log₂FC (gut vs SG) and shown by a colored circle outside the tree, from green (log₂FC = − 10) to red (log₂FC = 13). Proteins with no log₂FC of FPKM are left blank
