Effects of uga mutations on the expression of other light-regulated genes in mature plants. A, Northern-blot analyses of RNAs from 4-week-old light-grown (L) or dark-adapted (D) AG-5G, uga1-1, and uga1-2 were performed as described in Figure 3 with radiolabeled GAPB, TIM, FAB, LCHB, GAPC, CHS, and TUB probes. B, Each northern-blot analysis was repeated three times and quantified. The average densitometric value of each gene from light-grown AG5G is taken as 1. Error bars = sds.
