Values are mean ± sd.

    • F1-a Phase values are normalized to the period length and are given in circadian time (CT = phase/period × 24 h).

    • F1-b P value from Student's two-tailed heteroscedastic t test comparing the mutant value with Col is given in parentheses. The oop1 and phyB-9values were not significantly different within any treatment.
