Figure 6.

Comparison of the level of GA2ox mRNAs in seedlings grown in dark or continuous blue light. Six-day-old seedlings were grown in dark or continuous blue light (20 μmol m⁻² s⁻¹), the levels of mRNA expression are shown as the RT-PCR gel images (left) and the relative signal intensities (right). The mRNA expression of GA2ox genes in the wild-type or cry1cry2 mutant are shown in A. An independent experiment shows the levels of GA2ox1 mRNA expression in 6-day-old wild type and the indicated photoreceptor mutants grown in the dark or continuous blue light (B).
