(A) Expression pattern of MB315B-GAL4 line. (B) Luminescence of DAN-aSP13 neurons expressing Lola-LUC reporter (MB315B-GAL4>UAS-FLP; Lola>stop>-LUC) normalized to luminescence of the genetic control (UAS-FLP; Lola>stop>LUC). Mean luminescence of the wild-type males trained in single pair assays as indicated with virgin female (red, n = 24) or naïve males (black, n = 20) shown as a solid line with SEM indicated as thin vertical lines. (C) Luminescence of DAN-aSP13 neurons expressing Lola-LUC reporter (MB315B-GAL4 > UAS FLP; Lola > stop > LUC) normalized to luminescence of the genetic control (UAS-FLP; Lola>stop>LUC). Mean luminescence of the wild-type males trained in single pair assays as indicated with mated female (red, n = 22) and naïve males (black, n = 19) is shown as a solid line with SEM indicated as thin vertical lines. (D) Sleep profile of the wild-type males that were trained for 6 hr with mated females as indicated (red, n = 16) and naïve males (black, n = 16). Sleep time was plotted in 30 min bins. (E) SIs of wild type males trained as indicated with a mated female in single pair assays and tested 24 hr later. P value is for Ho SI = 0; ***p<0.001, ns p>0.05. Permutation test. (F) Sleep profile of the wild-type males that were trained for 1 hr with mated females (red, n = 16) and naïve males (black, n = 16). Sleep time was plotted in 30 min bins. (G) CIs of the wild-type or dopR1 mutant males during 6 hr training in single pair assay w a mated female. P value is for Ho CIwild-type = CIDopR1; ***p<0.001. Mann-Whitney-Wilcoxon test. (H) SIs of the wild-type or dopR1 mutant males tested 24 hr after training for 6 hr with mated females. P value is for Ho SI = 0; ***p<0.001, ns p>0.05. Permutation test.
