Evolution of digestive enzyme genes in A. suturalis. a Gene number comparison of digestive enzyme genes between A. suturalis and other species in Hemiptera. b Phylogenetic relationships and sequence identity of A. suturalis with A. lucorum. c, d Maximum likelihood phylogenetic and chromosomes distribution of SPs and carboxypeptidases genes in A. suturalis and A. lucorum. e Expression profiles of A. suturalis alpha-amylases, aminopeptidases, carboxypeptidases, cathepsins, glucosidases, lipases, phospholipases, PG, and SP genes from individuals at different tissues and developmental stages. The color intensity changes with the relative expression from low (green) to high (red). The color bar above the heatmap indicates different gene families or subfamilies.
