Circadian rhythms in Neurospora crassa: clock mutant effects in the absence of a frq-based oscillator.

Abstract excerpt

In Neurospora, the circadian rhythm is expressed as rhythmic conidiation driven by a feedback loop involving the protein products of frq (frequency), wc-1 (white collar-1), and wc-2, known as the frq/wc (FWC) oscillator. Although strains carrying null mutations such as frq(10) or wc-2Delta lack a functional FWC oscillator and do not show a rhythm under most conditions, a rhythm can be observed in them by the...
