Light reception and circadian behavior in 'blind' and 'clock-less' mutants of Neurospora crassa
Light sensing and daily activity in blind and internal clock-deficient Neurospora crassa mutants
AI simplified
Abstract
Light-regulated development occurs in individual mutant strains of Neurospora crassa.
- WHITE COLLAR-1 and WHITE COLLAR-2 are necessary for light responses, but not for light-regulated development.
- Both white collar mutant strains display similar patterns in light-regulated conidiation despite having distinct molecular profiles.
- Different sensitivities to light intensity were observed between the two strains.
- The findings suggest the presence of an unidentified photoreceptor involved in the light response.
- Circadian clock components in the mutant strains indicate that additional factors outside the WC-FRQ loop may contribute to the circadian system.
