Insertion at the beginning of the first intron.
Insertion in the first intron of cwo.
56% of mutant flies are arrhythmic for locomotor activity during the first 4 days in free running conditions. The remaining flies have weaker and longer rhythms than controls. After 4 days in constant darkness, 100% of the mutant flies are arrhythmic.
cwoe04207/cwof05073 flies show long and weak locomotor activity rhythms.
Homozygotes and cwoe04207/cwof05073 flies show dramatic reductions in the strength of behavioural circadian rhythms under constant darkness conditions.
cwoe04207/Df(3R)ED5495 flies show reductions in the strength of behavioural circadian rhythms under constant darkness conditions (DD); flies show rhythmicity immediately upon transfer to DD, but the rhythms dampen. Under light-dark conditions, cwoe04207/Df(3R)ED5495 flies show a reduction in morning anticipation (the magnitude of the activity increase preceding lights-on).
cwoe04207/cwof05073 is rescued by Scer\GAL4tim.PE/cwoUAS.cKa
