  Tor, Tsc1, Rheb, Atg5 and Atg7 genes expression was silenced in per-positive cells. Period of locomotor activity rhythm was measured in DD conditions (mean +/- SE). Representative actograms were presented. As a control, the progeny of per-Gal4 and UAS-Val10-GFP crossing was used. After silencing the Tor gene, the period of locomotor activity rhythm was significantly shorter than in the control [U Mann-Whitney Test, *** for p≤0,001]. Silencing the Tsc1 gene caused a slight lengthening in the period of the rhythm.
