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

Topological and functional characterization of an insect gustatory receptor. [PDF]
PLoS ONE, 2011 Insect gustatory receptors are predicted to have a seven-transmembrane structure and are distantly related to insect olfactory receptors, which have an inverted topology compared with G-protein coupled receptors, including mammalian olfactory receptors ...

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

A pair of pharyngeal gustatory receptor neurons regulates caffeine-dependent ingestion in Drosophila larvae [PDF]
Frontiers in Cellular Neuroscience, 2016 The sense of taste is an essential chemosensory modality that enables animals to identify appropriate food sources and control feeding behavior. In particular, the recognition of bitter taste prevents animals from feeding on harmful substances. Feeding

Functional analysis of a bitter gustatory receptor highly expressed in the larval maxillary galea of Helicoverpa armigera. [PDF]
PLoS Genetics, 2022 Many plant secondary substances are feeding deterrents for insects and play a key role in the selection of host plants. The taste sensilla of phytophagous insects contain gustatory sensory neurons sensitive to deterrents but the molecular basis of ...

Genome-Wide Identification of the Gustatory Receptor Gene Family of the Invasive Pest, Red Palm Weevil, Rhynchophorus ferrugineus (Olivier, 1790) [PDF]
Insects, 2021 The red palm weevil (Rhynchophorus ferrugineus) is a highly destructive pest of oil palm, date, and coconut in many parts of Asia, Europe, and Africa. The Food and Agriculture Organization of the United Nations has called for international collaboration ...

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 ...

Ionotropic Receptors Mediate Drosophila Oviposition Preference through Sour Gustatory Receptor Neurons [PDF]
Current Biology, 2017 Summary Carboxylic acids are present in many foods, being especially abundant in fruits. Yet, relatively little is known about how acids are detected by the gustatory systems, whether they have a potential role in nutrition or provide other health ...

Oxalic Acid Inhibits Feeding Behavior of the Brown Planthopper via Binding to Gustatory Receptor Gr23a [PDF]
Cells, 2023 Plants produce diverse secondary compounds as natural protection against microbial and insect attack. Most of these compounds, including bitters and acids, are sensed by insect gustatory receptors (Grs).

Heterogeneity in the Drosophila gustatory receptor complexes that detect aversive compounds [PDF]
Nature Communications, 2017 Taste sensilla are Drosophila sensory organs containing taste neurons, which have differential tuning for bitter compounds. Here, the authors systematically examine what combinations of gustatory receptor genes confer a specific taste response profile in
