Abstract

Rhythmic frq transcription is essential for the function of the Neurospora circadian clock. Here we show that there is a circadian histone occupancy rhythm at the frq promoter that is regulated by FREQUENCY (FRQ). Using a combination of forward genetics and genome sequencing, we identify Clock ATPase (CATP) as an essential clock component. Our results demonstrate that CATP associates with the frq locus and other WCC target genes and promotes histone removal at these loci to allow circadian gene transcription. These results indicate that the rhythmic control of histone occupancy at clock genes is critical for circadian clock function.
