Identification of Periplaneta americana OR1-like (PameOR1-like). (A) Amino acid sequence alignment of PameOR1-like with previously identified PameOR1 and PameOR211. The letters are shaded by alignment strength. The positions of seven transmembrane helixes are illustrated. GenBank IDs: PameOR1, BET24496.1; PameOR2, BET24497.1. (B) Dot plot representation of nucleotide sequence identity between the protein-coding region of PameOR1 and that of PameOR1-like. The red shaded area indicates the region corresponding to the PameOR1 dsRNA and the riboprobes targeting PameOR1 that were used for in situ hybridization in our previous study11. Note that this region shows high-level sequence identity (87.4%). (C) Dot plot representation of protein sequence identity between PameOR1 and PameOR1-like.
