Wavelength-dependent gene expression of group 3 genes and two control genes (pgk and hli8) in the red spectral region determined by quantitative real-time PCR. qPCR expression ratios (relative to the data for darkness treatment) are average values ± standard errors for four independent PCR runs, each in triplicate (n = 12).
