"Evolution of chemosensation, and fatal chemosenstation”
Abstract:
My lab is interested in the mechanistic basis of evolutionary diversification of animals in response to the environment. As a model system, we use closely-related drosophilid species with distinct niches, which enables us to identify genetic and cellular changes underlying ecologically-relevant adaptations. I will present two unpublished projects. The first is concerned with the functional diversification of the odour-tuning properties of volatile acid-sensing neurons in drosophilids, which has led us to discover a novel type of signalling mechanism in peripheral chemical detection. The second is concerned with the evolution of tolerance to a natural fruit toxin, in which we combined experimental evolution in animals and CRISPR-based mutant screens in cell culture to identify new resistance loci.
