DA neurons are candidates for promoting a preference for laying eggs on the sucrose substrate. A, Reducing the dopamine receptors DR2, D2R, or DopEcR reduced the ability of TH neurons to promote sucrose preference, but reducing the receptor DopR had no effect. The following genotype abbreviations are used: (1) TH* in DopR: UAS-dTRPA1/+; DopR1, TH-GAL4/DopR1, (2) TH* in DR2: UAS-dTRPA1/+; DR2, TH-GAL4/DR2, (3) TH* in DopEcR: UAS-dTRPA1/+; DopEcR, TH-GAL4/DopEcR, and (4) TH* in D2R: D2R; UAS-dTRPA1/+; TH-GAL4/+. N = 23, 65, 34, 29, 70, 46, 73, 79, 61, 70 for columns, left to right. B, Antibody staining of TH in an adult female brain. Neurons in the boxed area are TH neurons that reside in the SOG area. C, Activating Ddc(HL5)-GAL4-expressing neurons did not trigger a preference for laying eggs on the sucrose substrate. The following abbreviations are used: (1) HL5/+: Ddc(HL5)-GAL4/+ and (2) HL5 > dTRPA1: Ddc(HL5)-GAL4/+; UAS-dTRPA/+. N = 34, 19, 43, 43, 18, 43 for columns, left to right. D–F, Ddc(HL5)-GAL4 labeled all the TH antibody-positive neurons in the SOG. D, Ddc(HL5)-GAL4 neurons labeled by mCD8-GFP. E, TH antibody staining of the same neurons as in D. F, Merged image. See also Figure 8F. PI, Preference Index. S, sucrose; P, plain.
