Figure 2. PER to acetic acid is mediated by the gustatory system, not the olfactory system.

Figure 2.

(A–B) Removing the olfactory organs did not affect PER to acetic acid in two-day starved flies (A) or fed flies (B) (p>0.05). (C) Acetic acid aversion in fed flies, measured by suppression of PER to 50 mM sucrose, was observed in both control flies and flies lacking olfactory organs. Flies lacking olfactory organs were generally more responsive than control flies. (D) Two-day starved flies homozygous for the poxn∆M22-B5 mutation showed decreased PER to acetic acid as compared to wild-type controls, poxn∆M22-B5/+ heterozygotes, and poxn∆M22-B5 homozygotes carrying a rescue transgene. In all experiments different groups were compared by two-way repeated measures ANOVA followed by Bonferroni’s post-tests (*p<0.05, **p<0.01, ***p<0.001). In panel C, responses within each group were compared to the response to 0% acetic acid using one-way repeated-measures ANOVA followed by Dunnett's post-tests (#p<0.05, ##p<0.01; symbols colored by group). n = 3–5 sets of flies.
