Amino acid sequences alignment of newly identified ORs in locust to odorant receptors from other insects. Residues conserved in >50% of the predicted proteins are shaded. The numbers to the right refer to the position of the last residue of each line. The positions of putative transmembrane domains (I–VII), which were predicted based on LmigOR1, are indicated with black bars. Accession numbers for the selected odorant receptors: TcasOR28: [GeneBank: EEZ99241]; TcasOR47: [GeneBank: EFA02940]; AmelOR2a: [GeneBank: XP_003250826]; BmorOR16: [GeneBank: NP_001104832]; PhumOR4: [GeneBank: XP_002427433]; DmelOR43a: [GeneBank: ADK48470]; DmelOR59a: [GeneBank: AAF47008].
