The oxidant diamide delays degradation of GUS transcripts in transformant MU7. Diamide at the final concentrations indicated was added to a light/dark-grown culture of transformant MU7 at 0 h of light (0L = 24D). In A, levels of GUS transcripts were about 108%, 128%, and 100% of transcript levels in the control sample for diamide concentrations of 0.5, 0.6, and 0.7 mm, respectively. In B, in the presence of 0.8 mm diamide, the level of GUS transcripts at 30 min of light (0.5L) was about 50% higher than in the control sample.
