Cucurbitacin B Activates Bitter-Sensing Gustatory Receptor Neurons via Gustatory Receptor 33a in Drosophila melanogaster. [PDF]

Mol Cells, 2020
The Gustatory system enables animals to detect toxic bitter chemicals, which is critical for insects to survive food induced toxicity. Cucurbitacin is widely present in plants such as cucumber and gourds that acts as an anti-herbivore chemical and an insecticide. Cucurbitacin has a harmful effect on insect larvae as well.

Genome-wide analysis of gustatory receptor genes and identification of the fructose gustatory receptor in Arma chinensis. [PDF]

Heliyon
Gustatory receptors (GRs) allow insects to sense tastes in their external environment. Gustatory perception is crucial for distinguishing between beneficial and harmful or toxic compounds, affecting survival. This study is the first to identify and classify the GR genes and investigate their expression in the predatory Arma chinensis. Thirteen GR genes

Ionotropic Receptors Mediate Drosophila Oviposition Preference through Sour Gustatory Receptor Neurons. [PDF]

Curr Biol, 2017
Carboxylic acids are present in many foods, being especially abundant in fruits. Yet, relatively little is known about how acids are detected by gustatory systems and whether they have a potential role in nutrition or provide other health benefits.

A Drosophila Gustatory Receptor Required for Strychnine Sensation. [PDF]

Chem Senses, 2015
Strychnine is a potent, naturally occurring neurotoxin that effectively protects plants from animal pests by deterring feeding behavior. In insects, such as the fruit fly, Drosophila melanogaster, bitter-tasting aversive compounds are detected primarily through a family of gustatory receptors (GRs), which are expressed in gustatory receptor neurons. We

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.

Avoiding DEET through Insect Gustatory Receptors [PDF]

Neuron, 2010
DEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b. However, it is controversial as to whether ORNs respond directly to DEET or whether DEET blocks the response to attractive odors.

Gustatory receptors in Lepidoptera: chemosensation and beyond [PDF]

Insect Molecular Biology, 2016
Abstract Lepidoptera is one of the most widespread insect orders and includes several agriculturally important insect species. Ecological success of the lepidopteran insects partly depends on their adaptive chemoreception tactics, which play an important role in the selection of hosts, egg‐laying sites and mates ...

Structure of an insect gustatory receptor

, 2023
SUMMARYGustatory Receptors (GRs) are critical for insect chemosensation and are potential targets for controlling pests and disease vectors. However, GR structures have not been experimentally determined. We present structures ofBombyx moriGr9 (BmGr9), a fructose-gated cation channel, in agonist-free and fructose-bound states.

Opposing chemosensory functions of closely related gustatory receptors

eLife, 2023
Abstract Most animals have functionally distinct populations of taste cells, expressing receptors that are tuned to compounds of different valence. This organizational feature allows for discrimination between chemicals associated with specific taste modalities and facilitates differentiating between unadulterated foods and foods ...

Stimulation of the gerbil's gustatory receptors by monosaccharides [PDF]

Brain Research, 1976
The gustatory responses of the Mongolian gerbil were tested with a large number of monosaccharides. Electrophysiological methods were used to record from the chorda tympani nerve. Methyl glycosides which have structural features in common with sucrose are the most effective monosaccharides for eliciting a neural response.
