Expression of PdfrScer\UAS.cMa under the combined control of Scer\GAL4Clk.int1-3 and Scer\GAL80Pdf.PS, but not under the control of either Scer\GAL4Clk.4.5F or Scer\GAL4Pdf.PU, rescues the lower night-onset preferred temperature decrease observed in Pdfr5304 homozygous mutant adults; Pdfr5304 homozygous mutant adults expressing PdfrScer\UAS.cMa under the combined control of Scer\GAL4Clk.int1-3 and Scer\GAL80Pdf.PS also display significantly higher daytime preferred temperature increase compared to controls.
Expression of PdfrScer\UAS.cMa in DN1[[p]]s under the control of Scer\GAL4Clk.4.5F restores normal light-dependent temperature preference in Pdfr5304 mutants.
The advanced evening peak of locomotor activity which is seen in Pdfr3369 flies under light-dark conditions is rescued by expression of PdfrScer\UAS.cMa under the control of one of Scer\GAL4Pdfr.B, Scer\GAL4cry.PE, Scer\GAL4tim.PE or Scer\GAL4dimm-929, but is not rescued by expression of PdfrScer\UAS.cMa under the control of one of Scer\GAL4P2.4.Pdf, Scer\GAL4cry.PZ or Scer\GAL4Aph-4-c232.
Under constant darkness conditions (measured on days 3-9), expression of PdfrScer\UAS.cMa under the control of Scer\GAL4cry.PZ restores strong rhythmic behavior in Pdfr3369 flies, but the phase is delayed 6-10 hours. In approximately 50% of the rhythmic flies this delay happens instantaneously, whereas in others it takes 3-4 days to shift and then free-run with a period of 23.7 hours.
Expression of pdfrScer\UAS.cMa using Scer\GAL4Clk.8.0 in a pdfr5304 background rescues the defects in morning anticipation and the timing of light-dark entrained evening behaviour.
Expression of pdfrScer\UAS.cMa using Scer\GAL4cry.PE in a pdfr5304 background restores the timing of evening behaviour and also promotes significant restoration of morning behaviour during light-dark entrainment and the first day of constant dark.
Expression of pdfrScer\UAS.cMa only in "evening" cells using Scer\GAL4cry.PE together with Scer\GAL80Pdf.PS in a pdfr5304 background rescues both the timing of evening behaviour and the magnitude of morning anticipation during light-dark entrainment and the first day of constant dark.
Expression of pdfrScer\UAS.cMa only in "morning" cells using Scer\GAL4P2.4.Pdf in a pdfr5304 background does not rescue the timing of either morning or evening behaviours during light-dark entrainment and the first day of constant dark.
Expression of pdfrScer\UAS.cMa using Scer\GAL4Clk.8.0 in a pdfr5304 background promotes significant rescue of rhythmicity and period length in constant dark.
Expression of pdfrScer\UAS.cMa using Scer\GAL4cry.PE in a pdfr5304 background rescues period length and partially restores rhythmicity in constant dark.
Expression of pdfrScer\UAS.cMa only in "evening" cells using Scer\GAL4cry.PE together with Scer\GAL80Pdf.PS in a pdfr5304 background does not rescue rhythmic power though does rescue period length.
Expression of pdfrScer\UAS.cMa only in "morning" cells using Scer\GAL4P2.4.Pdf in a pdfr5304 background has no significant effect on either free-running rhythmicity or period length in constant darkness.
Expression of pdfrScer\UAS.cMa using Scer\GAL4elav.PLu in a pdfr5304 background rescues all circadian rhythm phenotypes in both light-dark and constant dark conditions. Co-expression of Scer\GAL80Pdf.PS results in a substantial reduction in rescue of rhythmic power in constant dark, though doesn't affect the rescue of period length in constant dark.
Expression of pdfrScer\UAS.cMa using Scer\GAL4Pdfr-EY11181-GAL4 in a pdfr5304/pdfrEY11181-GAL4 background strongly rescues the reduced rhythmicity phenotype seen in constant dark conditions.
