Site of a 496 bp insertion and a 7bp deletion in exon 2 of cwo, resulting in the removal of exon 2 and frameshift in exon 3.
Homozygous mutants display a delayed evening activity peak in LD (12 h of light, 12 h of dark) compared to controls. In DD conditions (constant darkness) cwoPB9 flies have extended (26.5 hour) rhythms for at least 10 days.
Heterozygous flies display no difference in circadian period from controls.
cwoPB9/Df(3R)RMSY flies have long period rhythms compared to wild type.
cwoPB9 has abnormal circadian rhythm phenotype, enhanceable by per01/per[+]
cwoPB9 has abnormal circadian rhythm phenotype, enhanceable by perUAS.cBa/Scer\GAL4tim.PE/per01/per[+]
cwoPB9 has abnormal circadian rhythm phenotype, enhanceable by perUAS.cBa/per01/Scer\GAL4cry.PE/per[+]
Homozygous cwoPB9 flies with one copy of per01 show more severe lengthening of the circadian cycle than homozygous cwoPB9 alone.
The length of the circadian cycle is increased when perScer\UAS.cBa is expressed in homozygous cwoPB9 flies with one copy of per01 under the control of either a Scer\GAL4tim.PE or a Scer\GAL4cry.PE driver.
