Circadian leaf movement in WT and axr6-3 seedlings at 22°C and 18°C

Genotype	22°Ca		18°Ca
	Period ± SDb (h)	Rhythmic/ total	Period ± SDb (h)	Rhythmic/ total
WT	23.8±0.5	11/13	25.7±0.7	14/17
axr6-3	ARRc	0/12	26.0±1.1	11/18

Plants were entrained for 5 days under 12 h light:12 h dark cycles at the indicated temperature, then held in continuous white light (50 µmol m⁻² sec⁻¹) for 5 days.

^aData from two independent replicates.

^bThe variance-weighted mean period was determined as described previously (Millar et al., 1995b; Plautz et al., 1997). Only those period estimates with relative amplitude error values ≤0.25 and periods between 20 and 30 h were included in this analysis. SD, standard deviation.

^cARR, arrhythmic (indicates the absence of period estimates with relative amplitude error values ≤0.25 for any of the seedlings).
