Fig. 3. NPF regulates food choice downstream of SP signalling in mated females, and exogenous NPF promotes yeast preferences in virgins.

Fig. 3

a, Intake of sucrose or yeast measured by dye assay in females mated to SP-producing or SP-deficient males (SP0/Df(3L)delta130). Sucrose, n = 15 NPFgut> females mated to SP+ males, n = 15 NPFgut> females mated to SP-mutant (SPnull) males, n = 14 NPFgut>NPFiTRiP females mated to SP+ males. Yeast, n = 15 NPFgut> females mated to SP+ males, n = 20 NPFgut> females mated to SP-mutant males, n = 13 NPFgut>NPFiTRiP females mated to SP+ males. b, Consumption preference using two-choice dye assay; n = 25 NPFgut> virgins, n = 24 NPFgut> females mated to SP+ males, n = 18 NPFgut> females mated to SP-null males, n = 21 NPFgut>NPFiTRiP females mated to SP+ males. c,d, Consumption preference of w1118 virgin females with or without NPF injection (c) and virgin and mated females (d) (with and without NPF injections) with knockdown of SPR in Ppk+ neurons (ppk>SPRi) using two-choice dye assay. c, n = 19 w1118 virgins, n = 20 w1118 virgins with NPF injection. d, n = 11 virgin ppk>SPRi females, n = 12 mated ppk>SPRi females, n = 12 mated ppk>SPRi females with NPF injection. Bars represent mean ± s.e.m. Box plots indicate minimum, 25th percentile, median, 75th percentile and maximum values. NS, not significant. a (left), b,d, One-way Kruskal–Wallis ANOVA with Dunn’s multiple-comparisons test. a, Right, one-way ANOVA with Dunnett’s multiple-comparisons test. c, Two-tailed unpaired Mann–Whitney U-test.
