FIGURE 4.
Leaf flattening and positioning and hypocotyl elongation of WT and mutant plants. (A) Leaf flattening and positioning in the WT and mutants grown under 70 μmol m−2 s−1 white light for about 4 weeks. Red arrows indicate the different leaf positioning phenotypes between the single and double mutants. (B) Hypocotyl elongation of 7-day-old WT and mutant plants under 70 μmol m−2 s−1 white light, with or without 30 μmol L−1 GR24. Scale bars represent 1 cm.
