Flies expressing qsmdsRNA.Scer\UAS under the control of Scer\GAL4tim.PE exhibit robust, long-period locomotor rhythms in constant dim white light, in contrast to control flies which largely show arrhythmic behavior in these conditions.
Under bright (2500 lux) constant light conditions, between 50 and 85% of flies expressing qsmdsRNA.Scer\UAS under the control of Scer\GAL4tim.PE show robust locomotor activity rhythmicity, with an average period length of 27.2 hours.
Under dim (35-55 lux) constant light conditions, over 75% of flies expressing qsmdsRNA.Scer\UAS under the control of Scer\GAL4tim.PE show robust locomotor activity rhythmicity, with an average period ranging from 26.6 to 28.5 hours (depending on the lines used), whereas control animals are largely arrhythmic under these conditions.
76.4% of flies expressing qsmdsRNA.Scer\UAS under the control of Scer\GAL4qsm-NP2664 in a qsmNP2664/+ background show robust locomotor activity rhythmicity under dim constant light conditions.
50% of flies expressing qsmdsRNA.Scer\UAS under the control of Scer\GAL4qsm-NP6258 in a qsmNP6258/+ background show robust locomotor activity rhythmicity under dim constant light conditions.
