The crack of dawn, the crack of doom".

Pc3 pulsations of dawn origin correspond to (R<1).
KaiA overexpression activates "dusk genes" and represses "dawn genes," whereas KaiC overexpression results in the opposite effect, that is, repression of "dusk genes" and activation of "dawn genes".
Beware dusk and dawn both often signal the onset of these swarms.
Hd3a mRNA levels increased beginning at dawn with a peak at the onset of light in wild type, but in the mutant, they increased from the onset of light and had a peak at the onset of dark in the mutant (Fig. 5E, F), indicating that Hd1 regulates Hd3a.
The predicted principal (group I) sigma factor (rpoD, PMM0496) peaks two hours after the onset of darkness, and the final sigma factor (PMM1629) peaks at dawn.
Experimentally, if the onset of darkness unexpectedly occurs only 6 hr after the previous dawn in plants previously grown in 12-hr light/12-hr dark conditions, the starch is degraded too quickly, while for an unexpected onset of darkness at 8 hr, the starch degradation occurs at the appropriate rate (Lu et al., 2005; Graf et al., 2010).
