Sensory neuron population expansion enhances odour tracking through relaxed projection neuron adaptation. Nature Com. (https://www.nature.com/articles/s41467-024-50808-w)
Here we investigate the genetic basis, physiological consequence and behavioural impact of olfactory sensory neuron number expansion. We show that the increase of peripheral sensory neurons is a complex genetic trait and leads to loss of second order habituation in D. sechellia compared to D. melanogaster. Moreover, it contributes to enhanced odour tracking. Our study delivers first mechanistic insights into how neural circuit architecture affects signal processing in the olfactory system.

In this study, we investigate how copy number variation in olfactory receptor genes contributes to evolutionary adjustments of odor tuning across species. Contrary to the widely accepted view that olfactory sensory neurons express a single tuning receptor, we show that this is not necessarily evolutionary conserved and positive selection acts on multiple, co-expressed copies in closely related species of D. melanogaster.

Mate discrimination among subspecies through a conserved olfactory pathway. Sci Adv. (https://www.science.org/doi/10.1126/sciadv.aba5279)
Here we use four subspecies of Drosophila mojavensis as model to study the role of pheromone signaling in speciation. We identify male specific pheromones that differ between subspecies. Surprisingly, the corresponding female pheromone detecting pathways are conserved. This indicates that subspecies-specific behaviors arise from differential central interpretation of the same peripheral cues. Our study is an important example for how behaviors can evolve through divergence at various levels.

In this study, we establish D. sechellia as a neurogenetic model species to study behavioral evolution. We investigate, by the use of genetic tools, which olfactory pathways contribute to the increased attraction of D. sechellia to its host fruit. We test the causal role of selected residue changes within one olfactory receptor to behavioral phenotypes and identify neuroanatomical changes in the periphery and the central brain. This is an intriguing example of how genes, neurons and circuits are linked to an ecologically relevant behavior.
