Fig 4. Most cycling gene expression is specific to one group of circadian neurons.

In all figures, LNvs are shown in green, LNds are shown in blue, DN1s are shown in read, and TH are shown in orange. A) Timeless (tim) cycles in all three neuronal groups with similar phase and expression level. Transcript levels are represented as reads/million total reads in a log base 2 scale. Two independent six timepoint datasets are concatenated to show cycling. B) Overlap of the high-confidence (HC) cycling transcripts found in the four neuronal groups. Only 4 HC cycling transcripts are in common in the 3 groups of circadian neurons. C) Dh31 is a HC cycling transcript in both the LNvs (green) and DN1s (red) with peak expression in the morning. The dotted line denotes the 3’end of the LNv specific Dh31 isoform. The isoform of Dh31 expressed in DN1s has an extended 3’-UTR. See also Fig 3, S1 Fig and S2 Fig.
