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 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

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 ...

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 ...

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 ...

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.

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).

The full repertoire of Drosophila gustatory receptors for detecting an aversive compound. [PDF]
Nature Communications, 2015 The ability to detect toxic compounds in foods is essential for animal survival. However, the minimal subunit composition of gustatory receptors required for sensing aversive chemicals in Drosophila is unknown.

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
