Phylogenetic relationships of 160 odorant-binding proteins (OBPs) from seven Hemiptera species: Halyomorpha halys, Apolygus lucorum, Adelphocoris lineolatus, Lygus lineolaris, Adelphocoris suturalis, Chinavia ubica, and Tropidothorax elegans. The branch leading to ‘Plus-C’ odorant-binding proteins (OBPs) is marked in blue.
