[i] The “Ref. D. m. wrigleyi” represents the annotation in the reference genome used to perform the gene annotation for our long-read ONT genomes. HLAU genes are separated according to their functions: localization—odorant-binding proteins (OBP) and odorant receptor (OR), acceptance—gustatory receptor (GR) and ionotropic receptor (IR), and host usage—ATP-binding cassette (ABC), carboxylesterase (EST), glutathione S-Transferase (GST), glycosyltransferase (UDP), and cytochrome P450 (CYP).
