Circadian period of LUC activity rhythms in toc1
| LUC Marker | Genotype | Organs | Period | se | n |
|---|---|---|---|---|---|
| h | |||||
| CAB | + | Aerial | 24.3a | 0.08 | 4 |
| CHS | + | Aerial | 25.1 | 0.37 | 5 |

Plants were maintained as described for Figure 2B and Table I. Period estimation and statistical comparisons were performed as described in “Materials and Methods.” All comparisons of toc1 versus wild type for a given marker and tissue, P < 0.0001; CHS in aerial tissues versus roots, P > 0.15 in both wild type and toc1. All lines are in the C24 background. The significance levels of t tests comparing the mean periods were as follows: aCHS (+) versus CAB (+), P = 0.09. bCAB (toc1) versus CHS (toc1) in aerial organs, P < 0.005.
