摘要：SummaryCircadian patterns of locomotor activity are influenced by social interactions. Studies on insects highlight the importance of volatile odors and the olfactory system. Wild-typeDrosophilaexhibit immediate re-entrainment to new light:dark (LD) cycles, whereascrybandjetcmutants show deficits in re-entrainability. We found that both male mutants re-entrained faster to phase-shifted LD cycles when social interactions with WT female flies were promoted than the isolated males. In addition, we found that accelerated re-entrainment mediated by social interactions depended on both visual and olfactory cues, and the effect of both cues presented jointly was nearly identical to the sum of the effects of the two cues presented separately. Moreover, we found that re-entrainment deficits inperiod(per) expression-oscillation injetcmutants were partially restored by promoting social interactions. Our results demonstrated that, in addition to olfaction, social interactions through the visual system also play important roles in clock entrainment.Graphical AbstractDisplay OmittedHighlights•Interactions with WT females accelerates re-entrainment injetcandcrybmale mutants•Both visual and olfactory inputs contribute to fast re-entrainment injetcmutants•jetcmutants in groups re-entrain faster onperexpression rhythms than isolated oneAnimal Physiology; Biological Sciences; Chronobiology; Genetics; Neuroscience
