A combination of genetics, behavior and physiology demonstrate that cool and moisture sensing rely on overlapping combinations of sensory receptors in Drosophila.
Hygroreception, a poorly understood process critical to insect survival, depends on a small protein in the antenna of the fruit fly that was previously thought to transport odorants.
The neurons and receptors mediating moist air detection in Drosophila are identified, revealing that moist and dry air detection depend on overlapping Ionotropic Receptors and that these pathways are both critical for hygrosensation.
The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.
A parallel neuronal network architecture ensures control of basic feeding reflex circuits via integration of crossmodal sensory information to filter multiple biological events and enhance meaningful behavioral choice.
Whole endosome recording shows that chloride interacts with vesicular glutamate transporters as both allosteric activator and permeant ion, and although the mode of permeation differs, chloride and glutamate use a related conduction pathway.
Molecular-genetic, neural imaging and behavioral analyses reveal how Drosophila melanogaster sense fatty acids, important nutrient compounds, through multimeric Ionoptropic Receptors complexes.
Expression of Drosophila bitter receptors in taste neurons produced increased, decreased, or novel responses, supporting a model in which the response profile is determined by activation, inhibition, or competition among receptors.
