Circulating fructose regulates a germline stem cell increase via gustatory receptor-mediated gut hormone secretion in mated Drosophila. [PDF]
Sci Adv, 2023 Oogenesis is influenced by multiple environmental factors. In the fruit fly, Drosophila melanogaster, nutrition and mating have large impacts on an increase in female germline stem cells (GSCs).

The silkworm gustatory receptor BmGr63 is dedicated to the detection of isoquercetin in mulberry. [PDF]
Proc Biol Sci, 2022 Gustatory systems in phytophagous insects are used to perceive feeding stimulants and deterrents, and are involved in insect decisions to feed on particular plants.

Structural model for ligand binding and channel opening of an insect gustatory receptor. [PDF]
J Biol Chem, 2022 Insect gustatory receptors play roles in sensing tastants, such as sugars and bitter substances. We previously demonstrated that the BmGr9 silkworm gustatory receptor is a d-fructose–gated ion channel receptor.

Structure of an insect gustatory receptor
bioRxiv, 2023 Gustatory 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.

A gustatory receptor tuned to the steroid plant hormone brassinolide in Plutella xylostella (Lepidoptera: Plutellidae). [PDF]
Elife, 2020 Feeding and oviposition deterrents help phytophagous insects to identify host plants. The taste organs of phytophagous insects contain bitter gustatory receptors (GRs). To explore their function, we focused on PxylGr34, a bitter GR in Plutella xylostella

Gustatory receptor 28b is necessary for avoiding saponin in Drosophila melanogaster. [PDF]
EMBO Rep, 2019 Saponins function as a natural self‐defense mechanism for plants to deter various insects due to their unpleasant taste and their toxicity. Here, we provide evidence that saponin from Quillaja saponaria functions as an antifeedant as well as an ...

A Gustatory Receptor GR8 Tunes Specifically to D-Fructose in the Common Cutworm Spodoptera litura. [PDF]
Insects, 2019 Gustatory receptors (GRs) are crucial in the peripheral coding of the non-volatile compounds in insects, and thus play important roles in multiple behaviors including feeding, mating, and oviposition.
