a, b Action potentials evoked by various concentrations of HCl at L8 sensilla in flies misexpressing OtopLa or OtopLaE638A in Gr5a-positive GRNs. Arrows indicate the onset of taste stimuli. Data are presented as mean ± SEM. n = 10 animals, *p < 0.0001 (0.001–100 mM), unpaired two-tailed t-tests. c Feeding responses to neutral foods vs. foods with varying concentrations of HCl for wild-type flies and flies misexpressing OtopLa or OtopLaE638A. Data are presented as mean ± SEM. n = 10 trials, *p = 0.0029 (0.001 mM) and *p < 0.0001 (0.01, 0.1, 1, and 10 mM), one-way ANOVA tests. d PER responses to neutral and acidic foods in wild-type flies and flies misexpressing OtopLa or OtopLaE638A. Data are presented as mean ± SEM. n = 10 trials, *p < 0.0001 (0.001, 0.01, 0.1, and 1 mM), one-way ANOVA tests.
