Cellular identification of water gustatory receptor neurons and their central projection pattern in Drosophila [PDF]

Proceedings of the National Academy of Sciences, 2006
Water perception is important for insects, because they are particularly vulnerable to water loss because their body size is small. In Drosophila , gustatory receptor neurons are located at the base of the taste sensilla on the labellum, tarsi, and wing margins.

Evolution of a complex locus : exon gain, loss and divergence at the Gr39a locus in Drosophila [PDF]

, 2008
Background. Gene families typically evolve by gene duplication followed by the adoption of new or altered gene functions. A different way to evolve new but related functions is alternative splicing of existing exons of a complex gene.

Contribution of the T1r3 Taste Receptor to the Response Properties of Central Gustatory Neurons

Journal of Neurophysiology, 2009
T1r3 is a critical subunit of T1r sweet taste receptors. Here we studied how the absence of T1r3 impacts responses to sweet stimuli by taste neurons in the nucleus tractus solitarius (NTS) of the mouse. The consequences bear on the multiplicity of sweet taste receptors and how T1r3 influences the distribution of central gustatory neurons.

Trehalose Sensitivity of the Gustatory Receptor Neurons Expressing Wild-type, Mutant and Ectopic Gr5a in Drosophila [PDF]

Chemical Senses, 2005
Among ~70 candidate gustatory receptor genes identified from the Drosophila genome, Gr5a is the only gene that is allelic to a known gene, Tre, which controls taste sensitivity. Tre was discovered as an X-linked genetic polymorphism (Tre+ and Tre01) among wild populations and laboratory strains (Tanimura et al., 1982).

Electrophysiological Characterization of Responses from Gustatory Receptor Neurons of sensilla chaetica in the Moth Heliothis virescens [PDF]

Chemical Senses, 2007
Discrimination of edible and noxious food is crucial for survival in all organisms. We have studied the physiology of the gustatory receptor neurons (GRNs) in contact chemosensilla (insect gustatory organs) located on the antennae of the moth Heliothis virescens, emphasizing putative phagostimulants and deterrents.

Preliminary observations of the gustatory function of sensilla on antennae of the female Spodoptera littoralis (Lepidoptera: Noctuidae): from single compounds to complex natural stimuli [PDF]

Journal of Bioscience and Applied Research
The gustatory system in insects is composed of detectors screening different panels of ligands, which enable or suppress life behaviors depending on the context.

No functional contribution of the gustatory receptor, Gr64b, co-expressed in olfactory sensory neurons of Drosophila melanogaster

Frontiers in Ecology and Evolution, 2022
Chemosensation is essential for the survival of insects. Activities like searching for food, mating, and oviposition in the fruit fly, Drosophila melanogaster are to a great extent governed by chemical cues detected via olfaction and gustation.

Differential Expression Analysis of Chemoreception Genes in the Striped Flea Beetle Phyllotreta striolata Using a Transcriptomic Approach. [PDF]

PLoS ONE, 2016
Olfactory transduction is a process by which olfactory sensory neurons (OSNs) transform odor information into neuronal electrical signals. This process begins with the binding of odor molecules to receptor proteins on olfactory receptor neuron (ORN ...

Caffeine taste signaling in Drosophila larvae

Frontiers in Cellular Neuroscience, 2016
The Drosophila larva has a simple peripheral nervous system with a comparably small number of sensory neurons located externally at the head or internally along the pharynx to assess its chemical environment. It is assumed that larval taste coding occurs
