Q1707term
nocte1 mutant adults fail to synchronize circadian locomotor activity to 25[o] C:16 [o]C temperature cycles under constant light (LL) conditions, unlike controls; they have a significantly lower circadian clock entrainment index for locomotor activity rhythms following a 7 h delay under 25[o] C:27 [o]C temperature cycles in LL, compared to controls.
Mutant flies show a defect in temperature entrainment of behavioural rhythms; they show no anticipation of the transition to the cold phase and simply react to temperature changes (in contrast, wild-type flies anticipate the transition to the cold phase by an increase of their activity levels).
nocted07154/nocte1 files do not show normal entrainment to temperature cycles but show normal synchronisation to light-dark cycles in assays studying locomotor rhythms.
Mutant flies show an uncoordinated phenotype at 37[o]C, with more flies falling over the longer they are exposed to the high temperature. This temperature-dependent uncoordinated phenotype is largely suppressed if the humidity is greater than 90%.
nocte1, perBG.pLUC has abnormal locomotor behavior phenotype
Flies expressing perBG.T:Ppyr\LUC in a nocte1 background are able to entrain to a 12 hour:12 hour LD cycle at 25oC. In contrast to wild-type flies, perBG.T:Ppyr\LUC nocte1 flies fail to entrain to a 12 hour:12 hour 25oC:18oC temperature cycle in LL; these flies are constantly active throughout both temperatures, except for a drop in activity during a ~1 hour window shortly after transition to the cold phase. Activity levels are higher in the warm phase. Further, the flies fail to entrain to two consecutive warm:cold cycles in LL where the second cycle is phase advanced by 6 hours, instead they abruptly change their activity level at the time of temperature transition. The flies behave similarly to control flies when kept in constant darkness at a variety of constant temperatures.
