a, Mean normalized activity of the indicated Dmel genotypes under 12:12 h LD (left) and 16:8 h LD (right). n: 12:12 h LD, DmelPdf-Gal4/+ (31), DsecPdf-Gal4/+ (29), UAS-PdfRNAi/+ (47), DmelPdf-Gal4/UAS-PdfRNAi (34), DsecPdf-Gal4/UAS-PdfRNAi (30); 16:8 h LD, DmelPdf-Gal4/+ (34), DsecPdf-Gal4/+ (32), UAS-PdfRNAi/+ (16), DmelPdf-Gal4/UAS-PdfRNAi (31), DsecPdf-Gal4/UAS-PdfRNAi (24). b,c, Evening peak time for the flies shown in a under 12:12 h LD (b) and 16:8 h LD (c). d, Mean normalized predawn activity for the genotypes shown in a under 12:12 h LD. e, Mean normalized activity of the Pdf mutant and Pdf-rescue genotypes under 12:12 h LD (top) and 16:8 h LD (bottom) (combined data from two independent lines). n: 12:12 h LD, Pdf01 (30); DmelPdf,Pdf01 (89); DsecPdf,Pdf01 (86); 16:8 h LD, Pdf01 (16), DmelPdf,Pdf01 (59); DsecPdf,Pdf01 (79). f,g, Evening peak time for flies under 12:12 h LD (f) and 16:8 h LD (g) shown in e. n: Pdf01 (16); DmelPdf,Pdf01 no. 1 (29); DmelPdf,Pdf01 no. 2 (30); DsecPdf,Pdf01 no. 1 (38); DsecPdf,Pdf01 no. 2 (41). h, Mean normalized predawn activity for flies depicted in e under 12:12 h LD. n: Pdf01 (30); DmelPdf1,Pdf01 (40); DmelPdf1,Pdf01 (49); DsecPdf1,Pdf01 (44); DsecPdf2,Pdf01 (42). bd,fh, *P < 0.05, ***P < 0.001 (Wilcoxon tests with Bonferroni correction). fh, Results for independent species-specific rescue strains and pooled rescue strains are shown in box plots to the left and right of the dashed line, respectively; letters A–C indicate significant differences, P < 0.05 (Wilcoxon tests with Bonferroni correction).
