Geosmin is produced by a group of microbes, is highly aversive to Drosophila. We furthermore showed that Drosophila has one type of sensory neurons expressing an odorant receptor (OR 56a) that is extremely sensitive and fully dedicated to detect this compound. The Geosmin detection System is conserved...
