Abstract:Salt is a crucial for survival, while excessive NaCl can be detrimental. In the fruit fly, Drosophila melanogaster, an internal taste organ, the pharynx, is a critical gatekeeper impacting the decision to accept or reject a food. Currently, our understanding of the mechanism through which pharyngeal gustatory receptor neurons (GRNs) sense high salt are rudimentary. Here, we found that a member of the ionotropic receptor family, IR60b, is exclusively expressed in a pair of GRNs activated by high salt. Using a t… Show more
