Natural variation in odorant recognition among odorant-binding proteins in Drosophila melanogaster.
Chemical recognition is essential for survival and reproduction. Adaptive evolution has resulted in diverse chemoreceptor families, in which polymorphisms contribute to individual variation in chemosensation. To gain insights into the genetic determinants of individual variation in odorant recognition, we measured olfactory responses to two structurally similar odorants in a population of wild-...
متن کاملNatural variation, functional pleiotropy and transcriptional contexts of odorant binding protein genes in Drosophila melanogaster.
How functional diversification affects the organization of the transcriptome is a central question in systems genetics. To explore this issue, we sequenced all six Odorant binding protein (Obp) genes located on the X chromosome, four of which occur as a cluster, in 219 inbred wild-derived lines of Drosophila melanogaster and tested for associations between genetic and phenotypic variation at th...
متن کاملFunctional dissection of Odorant binding protein genes in Drosophila melanogaster
Most organisms rely on olfaction for survival and reproduction. The olfactory system of Drosophila melanogaster is one of the best characterized chemosensory systems and serves as a prototype for understanding insect olfaction. Olfaction in Drosophila is mediated by multigene families of odorant receptors and odorant binding proteins (OBPs). Although molecular response profiles of odorant recep...
متن کاملOdorant receptor polymorphisms and natural variation in olfactory behavior in Drosophila melanogaster.
Animals perceive and discriminate among a vast array of sensory cues in their environment. Both genetic and environmental factors contribute to individual variation in behavioral responses to these cues. Here, we asked to what extent sequence variants in six Drosophila melanogaster odorant receptor (Or) genes are associated with variation in behavioral responses to benzaldehyde by sequencing al...
متن کاملAre odorant-binding proteins involved in odorant discrimination?
Pheromone-sensitive sensilla trichodea of nine moth species belonging to six families and three superfamilies of Lepidoptera were immunolabelled with an antiserum against the pheromone-binding protein of Antheraea polyphemus. Strong immunolabelling of the sensillum lymph was observed in all long sensilla trichodea of A. polyphemus, A. pernyi (Saturniidae), Bombyx mori (Bombycidae) and Manduca s...
