Abstract Sour taste, which is elicited by low pH, may serve to help animals distinguish appetitive from potentially harmful food sources. In all species studied date, the attractiveness of oral acids contingent on concentration. Many carboxylic are attractive at ecologically relevant concentrations but become aversive beyond some maximal Recent work found that Drosophila ionotropic receptors IR25a and IR76b expressed sweet-responsive gustatory receptor neurons (GRNs) in labellum, a peripheral organ, mediate feeding behaviors toward dilute acids. Here, we disclose existence pharyngeal sensors D. melanogaster detect ingested also involved responses These rely IR51b, IR94a, IR94h, together with IR76b, drive We then demonstrate optogenetic activation either Ir94a + or Ir94h GRNs promotes an response, confirming their contributions behavior. Our discovery internal sour taste opens up new avenues for investigating sensation tastants insects.

Taste organs contain distinct gustatory receptors that help organisms differentiate between nourishing and potentially harmful foods. The detection of high pH levels plays a crucial role in food selection, but the specific responsible for perceiving elevated foods have remained unknown. By using

The question as to whether animals taste cholesterol is not resolved. This study investigates the fruit fly, Drosophila melanogaster , capable of detecting through their gustatory system. We found that flies are indifferent low levels and avoid higher levels. avoidance mediated by receptor neurons (GRNs), demonstrating can cholesterol. responsive GRNs comprise a subset also respond bitter substances. Cholesterol detection depends on five ionotropic (IR) family members, disrupting any these genes impairs flies’ ability Ectopic expressions IRs in reveals two classes receptors, each with three shared one unique subunit. Additionally, expressing receptors sugar-responsive confers attraction cholesterol, GRNs.
