Abstract excerpt

Gustatory stimuli, such as sugar, induce a behavioral response in Drosophila that involves extension of the proboscis and consumption of the sugar-containing solution. Addition of salt to the sugar solution inhibits this behavioral response. However, the mechanisms and gene products involved in the salt aversion response have not been described. Here, we report the identification of a locus, defective proboscis...
