<p>Flies of 21D-GAL4×UAS-mCD8-GFP <i>D. melanogaster</i> line were held in constant darkness (DD) and sacrificed at CT1 – 1 h from the beginning of subjective day, CT4 – 4 h from the beginning of the subjective day, CT13 – 1 h from the beginning of subjective night, CT16 – 4 h from the beginning of subjective night.
