Flies expressing ClkScer\UAS.cZa under the control of Scer\GAL4P2.4.Pdf show similar locomotor activity period under free-running conditions (total darkness) as controls but the percentage as well as the rhythmic power of the behavioral oscillations is somewhat decreased.
When ClkScer\UAS.cZa is driven by Scer\GAL4cry.PP, females have a aberrant circadian rhythm. Instead of the characteristic bimodal profile, the diurnal pattern has only a single peak dominating the light phase with little or no evening peak. Mutants have a shortened period. When ClkScer\UAS.cZa is driven by Scer\GAL4cry.PE, mutants have an altered diurnal behaviour. There is a single peak of activity around the time of lights-on and little or no evening peak.
ClkUAS.cZa, Scer\GAL4cry.PZ has abnormal circadian rhythm phenotype, non-enhanceable by Pdf01
ClkUAS.cZa, Scer\GAL4cry.PZ has abnormal circadian rhythm phenotype, non-suppressible by Pdf01
ClkUAS.cZa, Scer\GAL4P2.4.Pdf is a suppressor | partially of abnormal circadian rhythm phenotype of Scer\GAL4P2.4.Pdf, shnUAS.cMa
ClkUAS.cZa, Scer\GAL4P2.4.Pdf is a non-suppressor of abnormal locomotor rhythm | adult stage phenotype of Scer\GAL4P2.4.Pdf, Srrm1KK108396
ClkUAS.cZa/Scer\GAL4P2.4.Pdf is a non-suppressor of abnormal locomotor rhythm phenotype of tyfΔG14151
ClkUAS.cZa/Scer\GAL4P2.4.Pdf is a non-suppressor of abnormal locomotor rhythm phenotype of tyfe00614
ClkUAS.cZa, Scer\GAL4P2.4.Pdf, shnUAS.cMa has abnormal circadian rhythm phenotype
The loss of rhythmicity in locomotor activity under free-running (constant darkness) conditions characteristic for flies expressing SRm160KK108396 (and UAS-dicer2 to enhance the RNAi efficiency) under the control of Scer\GAL4P2.4.Pdf cannot be rescued by co-expression of ClkScer\UAS.cZa.
Co-expression of ClkScer\UAS.cZa with shnScer\UAS.cMa under the control of Scer\GAL4P2.4.Pdf results in an intermediate phenotype, with a shorter period than in Scer\GAL4P2.4.Pdf->shnScer\UAS.cMa flies, but a longer period than in Scer\GAL4P2.4.Pdf->ClkScer\UAS.cZa flies.
The weakened rhythmicity seen in tyfΔG14151 and tyfe00614 flies under constant darkness conditions is not suppressed by expression of ClkScer\UAS.cZa under the control of Scer\GAL4P2.4.Pdf.
