Altered expression of CYP72B1 affects hypocotyl responses to light. Hypocotyls of 6-day-old seedlings were measured after growth in the dark or varying intensities of white light (A), far-red light (B), blue light (C), or red light (D). The lines and symbols are Col-0 (●, black), phyB-4 (⋄, green), bas1-D phyB-4 (○, blue), BAS1 antisense line A2 from Fig. 1T (♦, purple), and det2–1 (▵, red). Both antisense lines had similar phenotypes.
