Abstract
Conidiation in Neurospora crassa occurs at midnight under various light conditions, indicating complex entrainment dynamics.
- The appearance of spore bands suggests integration of light signals rather than reliance on dawn or dusk alone.
- Symmetrical light/dark cycles influence the timing of conidiation, with a consistent delay linked to dusk.
- Temperature changes do not replicate the same synchronization effects as light, indicating specificity of the light signal.
- Posttranscriptional regulation plays a key role in the molecular mechanism of entrainment.
- Acute effects of zeitgeber stimuli, referred to as 'masking,' have been explored using Neurospora.
