The Neurospora crassa OS MAPK pathway-activated transcription factor ASL-1 contributes to circadian rhythms in pathway responsive clock-controlled genes

► Circadian clock control of the OS MAPK pathway leads to rhythms in expression of target genes. ► The ASL-1 transcription factor is necessary for normal stress responses of the target genes. ► ASL-1 is required for normal rhythmic expression of the target genes. ► Rhythmic posttranslational modification of ASL-1 is likely responsible for target gene rhythms.
