Expression of Mbs^Scer\UAS.cLa under the control of Scer\GAL4^P0.5.Pdf results in an increase in axonal volume and spread of s-LNv neuron projections compared to controls when expression is induced at ZT24 (dawn) and spread is measured 12 hours later.

In contrast to controls, which adjust their morning and evening activity peaks to align with seasonal dawn and dusk, flies expressing Mbs^Scer\UAS.cLa under the control of Scer\GAL4^P0.5.Pdf (restricted to the adult stages using Scer\GAL80^ts.αTub84B) are active later than control flies when exposed to a summer light:dark cycle (14 hours day:10 hours night). Timing of activity is unaffected compared to controls when the flies are exposed to a winter cycle (10 hours day:14 hours night). Normal locomotor activity is seen when the flies are kept in complete darkness (DD).

Mbs^UAS.cLa, Scer\GAL4^P0.5.Pdf is a suppressor of s-LNv Pdf neuron phenotype of Rho1^UAS.cMa, Scer\GAL4^P0.5.Pdf
