Nearest neural neighbors: moth sex pheromone receptors HR11 and HR13.
In moth sex pheromone olfaction systems, there is a stereotypical co-compartmentalization of two or sometimes three olfactory receptor neurons (ORNs) within single trichoid sensilla on which pheromone-sensitive odorant receptors (ORs) are differentially expressed. In this issue of Chemical Senses, Krieger et al. show through elegant double and triple in situ hybridization studies that in the mo...
متن کاملMoth Sex Pheromone Receptors and Deceitful Parapheromones
The insect's olfactory system is so selective that male moths, for example, can discriminate female-produced sex pheromones from compounds with minimal structural modifications. Yet, there is an exception for this "lock-and-key" tight selectivity. Formate analogs can be used as replacement for less chemically stable, long-chain aldehyde pheromones, because male moths respond physiologically and...
متن کاملHR11 and HR13 receptor-expressing neurons are housed together in pheromone-responsive sensilla trichodea of male Heliothis virescens.
The highly specific recognition of female-released sex pheromones in insects by sensory neurons of the male antenna requires specific receptors. Recently, a small family of related candidate pheromone receptors has been identified for a few moth species. In this study, the candidate pheromone receptor HR11 from Heliothis virescens has been characterized. HR11 was found to be expressed in numero...
متن کاملMoth pheromone receptors: gene sequences, function, and evolution
The detection of female-released species-specific sex pheromones in moths is mediated by the pheromone receptors that are expressed in the sensory neurons in the olfactory sensilla of conspecific male antennae. Since the pioneering studies on the tobacco budworm Heliothis virescens and the silkworm Bombyx mori a decade ago, genes encoding pheromone receptors have been identified from a number o...
متن کاملSpecificity Determinants of the Silkworm Moth Sex Pheromone
The insect olfactory system, particularly the peripheral sensory system for sex pheromone reception in male moths, is highly selective, but specificity determinants at the receptor level are hitherto unknown. Using the Xenopus oocyte recording system, we conducted a thorough structure-activity relationship study with the sex pheromone receptor of the silkworm moth, Bombyx mori, BmorOR1. When co...
