    A gustatory receptor tuned to the steroid plant hormone brassinolide in Plutella xylostella (Lepidoptera: Plutellidae)

    Ke Yang et al.
    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.

    Evolutionary shifts in taste coding in the fruit pest Drosophila suzukii

    Hany KM Dweck et al.
    The evolutionary transition of the agricultural pest Drosophila suzukii to egg laying on ripe fruits was paralleled with several gustatory innovations.
    1. Neuroscience

    Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

    Kathrin Steck et al.
    Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.

    A putative origin of the insect chemosensory receptor superfamily in the last common eukaryotic ancestor

    Richard Benton et al.
    Comparative genomics and three-dimensional protein modelling identify homologs of insect chemosensory receptors in unicellular eukaryotes and plants.

    Molecular basis of fatty acid taste in Drosophila

    Ji-Eun Ahn et al.
    Molecular-genetic, neural imaging and behavioral analyses reveal how Drosophila melanogaster sense fatty acids, important nutrient compounds, through multimeric Ionoptropic Receptors complexes.
    1. Neuroscience

    Gustatory-mediated avoidance of bacterial lipopolysaccharides via TRPA1 activation in Drosophila

    Alessia Soldano et al.
    Fruit flies can taste and avoid food contaminated with a bacterial toxin using the same channel protein that functions in humans as sensor of noxious chemical stimuli.
    1. Neuroscience

    Long-range projection neurons in the taste circuit of Drosophila

    Heesoo Kim et al.
    Taste pathways to higher brain are critical for learned responses to taste compounds.
    1. Neuroscience

    Bitter taste receptors confer diverse functions to neurons

    Rebecca Delventhal, John R Carlson
    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.

    Sleep-promoting effects of threonine link amino acid metabolism in Drosophila neuron to GABAergic control of sleep drive

    Yoonhee Ki, Chunghun Lim
    Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.
    1. Neuroscience

    Immediate perception of a reward is distinct from the reward’s long-term salience

    John P McGinnis et al.
    The experiences that are most rewarding at the time are not necessarily those that are remembered long-term.
