Statistical tests for altered sensitivity to red light among Arabidopsis lines expressing spruce clock genes.

Transgenic lines were compared against the corresponding Arabidopsis lines without transgene.
*P-value calculated from the interaction term Fluency rate x Line in a linear model including Line and Fluency rate, see materials and methods for details.
**Adjusted R2 (coefficient of determination) indicating model fit.
***Hypo and Hyper indicate that ectopic expressor lines were hypo- or hypersensitive to red light as compared to untransformed lines. Parentheses mark non-significant effects.
