OWL1 Is Specifically Involved in phyA-Dependent VLFR.

(A) Hypocotyl length under hourly pulses of FR light (0.5 μmol m−2 s−1, 5 min/h). Seedlings of the wild type (Col), two different owl1 alleles (owl1-1 and owl1-2), two overexpressing lines (OWL1-OE1 and OWL1-OE2), and phyA were grown for 4 d under these conditions. Hypocotyl elongation is displayed as a percentage of elongation relative to dark-grown seedlings of the same genotype.

(B) Cotyledon opening under hourly pulses of FR light (0.5 μmol m−2 s−1, 5 min/h).

(C) Fluence response curve under very low R light for 4 d. Hypocotyl length is displayed as percentage of elongation relative to dark-grown seedlings of the same genotype.

(D) Fluence response curve under continuous FR light. Seedlings were grown for 4 d under these conditions. Hypocotyl length is displayed as percentage of elongation relative to dark-grown seedlings of the same genotype. Error bars are sd.
