Abstract

The blue light photopigment cryptochrome (CRY) is thought to be the main circadian photoreceptor of Drosophila melanogaster. Nevertheless, entrainment to light-dark cycles is possible without functional CRY. Here, we monitored phase response curves of cry01 mutants and control flies to 1-hour 1000-lux light pulses. We found that cry01 mutants phase-shift their activity rhythm in the subjective ...
