Identification of an additional periplanone receptor family gene preferentially expressed in the male antennae of the American cockroach
Abstract Periplaneta cockroaches use periplanone analogs as female sex pheromones to attract males. We previously identified two periplanone receptor genes, PameOR1 and PameOR2, in the American cockroach Periplaneta americana. Here, we report the identification of PameOR1-like, an additional olfacto...

| description | Abstract Periplaneta cockroaches use periplanone analogs as female sex pheromones to attract males. We previously identified two periplanone receptor genes, PameOR1 and PameOR2, in the American cockroach Periplaneta americana. Here, we report the identification of PameOR1-like, an additional olfactory receptor resembling PameOR1 in P. americana. PameOR1-like showed high-level sequence similarity to PameOR1, and is preferentially expressed in the male antennae. Quantitative expression analysis revealed that, in the adult male antennae, the expression level of PameOR1 is 2.4-fold higher than that of PameOR1-like. Fluorescent in situ hybridization revealed that PameOR1 and PameOR1-like are co-expressed in the periplanone-A-responsive sensory neurons within the single walled-B sensilla on the male adult antennae. These data support the idea that PameOR1 and PameOR1-like are generated by a recent gene duplication event and play a redundant function in sex pheromone reception in P. americana. |
