Multimodal stimulus coding by a gustatory sensory neuron in Drosophila larvae [PDF]
Nature Communications, 2016 While gustatory systems have been extensively studied in adult Drosophila, not much is known about taste coding at the larval stage. Here, the authors investigate gustatory receptor neurons in larvae and find single neurons are capable of responding to ...

Gustatory Receptors: Not Just for Good Taste [PDF]
Current Biology, 2013 A recent study has found that a Drosophila gustatory receptor is required for thermotaxis. With other fly gustatory receptors having been shown to act in the detection of CO2, nutrients in the brain, and light, the roles of the so-called 'gustatory receptors' clearly go way beyond peripheral detection of non-volatile chemicals.

Evolution of gustatory receptor gene family provides insights into adaptation to diverse host plants in nymphalid butterflies. [PDF]
Genome Biol Evol, 2018 The host plant range of herbivorous insects is a major aspect of insect–plant interaction, but the genetic basis of host range expansion in insects is poorly understood.

Identification of putative fecundity-related gustatory receptor genes in the brown planthopper Nilaparvata lugens. [PDF]
BMC Genomics, 2018 The insect gustatory system plays a central role in the regulation of multiple physiological behaviors and the co-evolution between insects and their hosts. The gustatory receptors (Gr) are important to allow insects to sense their environment.

Molecular characterization of gustatory second-order neurons reveals integrative mechanisms of gustatory and metabolic information [PDF]
eLifeAnimals must balance the urgent need to find food during starvation with the critical necessity to avoid toxic substances to ensure their survival. In Drosophila, specialized Gustatory Receptors (GRs) expressed in Gustatory Receptor Neurons (GRNs) are ...

Early hexapod genomes reveal the deep origin of insect gustatory and odorant receptors [PDF]
Nature CommunicationsInsect smell and taste is primarily mediated through a chemoreceptor superfamily that includes three lineages of gustatory receptors—sugar, carbon dioxide, and bitter—and a distinct lineage of odorant receptors.

The taste of ribonucleosides: Novel macronutrients essential for larval growth are sensed by Drosophila gustatory receptor proteins. [PDF]
PLoS Biol, 2018 Animals employ various types of taste receptors to identify and discriminate between different nutritious food chemicals. These macronutrients are thought to fall into 3 major groups: carbohydrates/sugars, proteins/amino acids, and fats.

Stimulation of the gerbil's gustatory receptors by polyols [PDF]
Brain Research, 1976 The gustatory responses of the Mongolian gerbil were tested with 12 sugar alcohols. The electrophysiological effectiveness of the linear polyols as gustatory stimulants increased as the length of the carbon chain increased from 2 to 5. Six and 7 carbon acyclic polyols were no more effective than the pentitols. By comparison myoinositol, a cyclic polyol,

Mechanism of Acetic Acid Gustatory Repulsion in Drosophila [PDF]
Cell Reports, 2019 Summary: The decision to consume or reject a food based on the degree of acidity is critical for animal survival. However, the gustatory receptors that detect sour compounds and influence feeding behavior have been elusive.
