Fig. 1. cry2 affects de-etiolation under high fluence rates of white light. Seedlings of the wild type and of the phyA, phyB, cry1 and cry2 single, double, triple and quadruple mutant combinations were grown in darkness (D) or under white light photoperiods (WL) for 7 days. No significant differences in morphology among genotypes were observed for dark controls (for this reason only the wild type is shown). The figure is based on the analysis of 10 replicate boxes (100 seedlings) per genotype. The only statistically significant effect of the cry2 mutation on hypocotyl growth was in the PHYA PHYB cry1 background. The insets show (from left to right) the cotyledons in the wild type, phyA phyB cry1 and phyA phyB cry1 cry2 seedlings.
