Germination behavior of 35S:ARR1-SRDX seedlings under different light conditions. A, Germination rate after treatment by a white light pulse (5 min, 30 μE) and subsequent incubation in the dark. B, Germination rate after red (R), far-red (FR), or R/FR treatment. Seedlings were treated for 5 min with the indicated light and kept subsequently in the dark. Germination frequency was determined from batches of approximately 100 seeds after 7 d of dark incubation (n = 2). Error bars represent sd. Pairwise Student's t test was used to compare values with the wild type. No symbol, P > 0.05; *, 0.01 < P < 0.05; **, 0.001 < P < 0.01; ***, P < 0.001. ARR1-S-8 and ARR1-S-10 are two independent lines of 35S:ARR1-SRDX transgenic plants.
