Relationship between hypocotyl length of hy1 seedlings and concentration of bilin solutions added to agar media. At the beginning of light irradiation, 10 μl of PΦB (●) and PCB (○) in various concentrations, ranging from 0.001 to 2 mM of stock solutions, were added to 1 ml of agar media. If bilins are fully diffused to agar media, the final concentrations are 0.01–20 μM. (A) The seedlings were irradiated by the intermittent R light for 2 days (12 cycles). (B) The seedlings were irradiated by the intermittent FR light for 2 days (960 cycles). Error bars represent SE.
