Comparative gene sets among insects. a A phylogeny is shown constructed from 221 single-copy genes present in all species included in this analysis. The Pentatomidae (red) form a cluster within the Hemiptera (yellow) order which forms a sister clade to Holometabola (blue). The tree is rooted with the crustacean Daphnia pulex (not shown). Black dots indicate nodes with bootstrap support > 75%, whereas gray dots indicate nodes with bootstrap support between 50 and 75%. The scale bar is in substitutions per site. b Orthology profile of stinkbugs (names shown in red), compared to other insects. Note the large fraction of species-specific genes in N. viridula (Nviri) which is very similar to what has been previously documented for the pea aphid A. pisum (Apisu). Species names prefixed with “[T]” indicate that the unigene set was obtained from a transcriptome assembly; for the remaining insect species the data were obtained from a genome assembly. Species names abbreviations: Nviri – N. viridula; Ahila – A. hilare; Pstal – P. stali; Hhaly – H. halys; Cruti – C. rutilans; Ofasc – Oncopeltus fasciatus; Rprol – Rhodnius prolixus; Clect – Cimex lectularius; Dcitr – Diaphorina citri; Apisu – A. pisum; Tcast – Tribolium castaneum; Dmela – Drosophila melanogaster; Dplex – Danaus plexippus; Amell – Apis mellifera
