Figure 2. Test of IRs and sweet‐sensing GRs to detect vitamin C.

Figure 2

  1. Tip recording screens performed with 31 Ir mutants and control (w 1118 ) from L4 and L6 sensilla stimulated with 50 mM vitamin C, n = 10–12.
  2. Tip recording screens performed with sweet Gr mutants from L4 and L6 to 50 mM vitamin C, n = 10–13.
  3. Genetically recovered flies of Ir25a 2 and Ir76b 1 driven by their own GAL4 or Gr64f‐GAL4 with the wild‐type cDNA transgene. +/− indicate the presence or absence of the transgene, respectively, n = 10–15.
  4. Genetically recovered flies of Gr5a, Gr61a, Gr64b, Gr64c, and Gr64e mutants driven by their own GAL4 or Gr64f‐GAL4. +/− indicate the presence or absence of the transgene, respectively, n = 10–21.

Data information: All error bars represent the SEM. Multiple sets of data were compared using single‐factor ANOVA coupled with the Scheffe's post hoc test. Asterisks indicate statistical significance compared with the control. **P < 0.01.
