Figure 6.

PsGA20ox1, PsGA3ox1, PsGA2ox1, and PsGA2ox2 mRNA levels after transfer to red light in WT, GA₁-overproducing (sln), and GA₁-deficient (ls-1) mutant lines of pea, as shown by northern analysis. Seedlings were grown in continuous dark (D) for 7 d prior to transfer. The dark 2-h sample (D2) represents the relevant mRNA level in continuous darkness at the time of sampling of seedlings transferred to R for 2 h. Immediately below each northern blot is the gel showing the corresponding ribosomal RNAs (stained with ethidium bromide) to indicate the loading of lanes.
