A global search for novel transcription factors impacting the <i>Neurospora crassa</i> circadian clock

Abstract

In order to identify new players modulating the circadian clock in the model Neurospora crassa, we adopted a reverse genetics strategy. Thus, we focused on transcription factors knockouts and crossed them to strains containing circadian luciferase reporters. Our screen covered close to 60% de the 302 genes encoding for such proteins in Neurospora, identifying that 23 of them appear to modulate period, while none of the tested ones (besides the classic core-clock components) are essential for daily rhythms.
