Temporal niche partitioning through olfactory cell type evolution

This study shows how Drosophila sechellia evolved a specialized olfactory receptor to detect ripe noni fruit, enabling temporal niche partitioning by reducing competition and parasitization.

Laboratory and wild Drosophila sechellia have conserved niche specialization phenotypes

The paper compares laboratory and wild Drosophila sechellia to assess if lab strains retain specialization phenotypes from their natural environment.

A GPCR signaling pathway in insect odor detection

The paper identifies a GPCR signaling pathway in Drosophila that modulates olfactory tuning properties in insect odor detection.

Olfactory projection neuron rewiring in the brain of an ecological specialist

The paper compares olfactory projection neuron rewiring in Drosophila sechellia and Drosophila melanogaster to show how central brain wiring changes support ecological specialization.

Sensory neuron population expansion enhances odor tracking without sensitizing projection neurons

The paper shows that expanded sensory neuron populations in Drosophila enhance odor tracking without increasing projection neuron sensitivity.

Targeted molecular profiling of rare cell populations identifies olfactory sensory neuron fate and wiring determinants

The paper uses Targeted DamID to profile rare Drosophila sensory neurons, identifying transcription factors and guidance molecules involved in neuron fate and wiring.

In vivo assembly and trafficking of olfactory Ionotropic Receptors

This study investigates the role of the co-receptor's ligand-binding domain in the assembly and trafficking of olfactory Ionotropic Receptors, revealing its importance in endoplasmic reticulum exit.

An expression atlas of chemosensory ionotropic glutamate receptors identifies a molecular basis of carbonation detection

The paper identifies a molecular basis for carbonation detection using Drosophila IRs, showing that Ir56d, along with co-receptors, is essential for carbonation and fatty acid sensing.

Distinct combinations of variant ionotropic glutamate receptors mediate thermosensation and hygrosensation in Drosophila

The paper identifies IR93a as a key receptor involved in both thermosensation and hygrosensation in Drosophila, showing it functions with different partners in distinct sensory pathways.
