Fig. 4.
dra1 shows a reduced PHYB expression response to shade. Seven-day-old white light (W)-grown seedlings of the wild type (WT) and dra1 were transferred to simulated shade (W+FR) for 2 h. Relative PHYB expression was measured by quantitative RT-PCR, normalized to the ACT2 control gene. Data represent the mean ±SE from five independent batches of 20 seedlings.
