Double and Triple Mutant Analysis in Response to Excess Light.
Wild-type (WT) and the different mutant seedlings were grown for 10 d in continuous white light (100 μmol quanta m−2 s−1) at 23°C and shifted to excess light (3 h 1000 μmol quanta m−2 s−1). Expression of genes from the cry1-dependent regulon GPX7 (A) and ELIP2 (B) was analyzed using real-time PCR. The expression following exposure to high light was related to the control of each genotype. The results were normalized to the expression level of At4g36800 encoding a ubiquitin-protein ligase-like protein. The mean (±sd) of nine biological replicates is shown.
