Wake up and smell the piper! Olfactory receptor repertoires reflect dietary s...Laurel Yohe
NASBR 2015 (North American Society for Bat Research) conference in Monterey, CA. Olfaction is a primary sense used for food detection in plant-visiting bats. Olfactory receptors are diverse family of genes that code for odorant detectors in mammals. However, the relationship between dietary specialization and olfactory receptor repertoires remains unknown. New World Leaf-nosed bats (Phyllostomidae) have evolved adaptations to exploit plant resources, and many lineages are plant specialists. Recent analyses suggest the primarily frugivorous subfamily Stenodermatinae has a distinct olfactory receptor repertoire compared to insectivorous species, but there is no work to date examining whether species that specialize on particular plant genera also have more specialized olfactory receptors. We sequenced the olfactory receptor repertoires of three species of Carollia, a bat genus that varies in its dietary specialization to the soft fruits of Piper plants. We compared the olfactory receptor repertoires and the function of orthologous receptors among Carollia species that vary in their degree of specialization on Piper. The most dedicated Piper specialist, Carollia castanea, had a unique set of olfactory receptors not shared by the two more generalist species. These unique receptors potentially enable castanea to detect its primary resource to an extent that the other species cannot. This suggests relaxed selection on receptors in species with more specialized diets, and purifying selection in more generalist species that would maintain the ability to detect a wide range of odorant molecules.
