Circadian Clock-Controlled Genes Isolated From Neurospora Crassa Are Late Night- To Early Morning-Specific, Deborah Bell-Pedersen, Mari L. Shinohara, Jennifer J. Loros, Jay C. Dunlap

An endogenous circadian biological clock controls the temporal aspects of life in most organisms, including rhythmic control of genes involved in clock output pathways. In the fungus Neurospora crassa, one pathway known to be under control of the clock is asexual spore (conidia) development. To understand more fully the processes that are regulated by the N. crassa circadian clock, systematic screens were carried out for genes that oscillate at the transcriptional level. Time-of-day-specific cDNA libraries were generated and used in differential screens to identify six new clock-controlled genes (ccgs). Transcripts specific for each of the ccgs …
