Abstract

fetched live from OpenAlex

Plants and animals use day or night length for seasonal control of reproduction and other biological functions. Overwhelming evidence suggests that this photoperiodic mechanism relies on a functional circadian system. Recent progress has defined how flowering time in plants is regulated by photoperiodic control of output pathways, but the underlying mechanisms of photoperiodism remain to be described. The authors investigate photoperiodism in a genetic model system for circadian rhythms research, Neurospora crassa. They find that both propagation and reproduction respond systematically to photoperiod. Furthermore, a nonreproductive light-regulated function is also enhanced under certain photoperiodic conditions. All of these photoperiodic responses require a functional circadian clock, in that they are absent in a clock mutant. Night break experiments show that measuring night length is one of the mechanisms used for photoperiod assessment. This represents the first formal report of photoperiodism in the fungi.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
