White, black and gray bar denote light phase, dark phase and subjective light phase, respectively.  The number of flies (n=37-54) , period (n=26-50), power of rhythmicity (P-S) and percentage of rhythmic flies (rhythmicity) are indicated in right panel.  Mann-Whitney U test for period (*p$<$0.05) and welch's t-test for P-S (***p$<$0.001).   \textbf{(b)} Transcriptional oscillation of \emph{period} gene in \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} in DD. black and red lines denote \emph{w\textsuperscript{1118}} and \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} respectively.  rp49 was used for normalization. Data are represented as mean $\pm$ SEM.  a.u., arbitrary unit.
