Overexpression of ZmPHYC1 andZmPHYC2 confers a hypersensitive response to red and blue light, but not far‐red light. (a) Phenotype of Col‐0 (wild type), phyC‐2 mutant, ZmPHYC1‐OE and ZmPHYC2‐OE transgenic lines (in the wild‐type Col‐0 background) grown in continuous darkness (Dk), red (Rc, 30 μmol photons m⁻² s⁻¹), far‐red (FRc, 2.1 μmol photons m⁻² s⁻¹) or blue (Bc, 1.0 μmol photons m⁻² s⁻¹) light conditions for 4 days. Bars = 2 mm. (b‐e) Quantification of hypocotyl length of the seedling plants shown in (a). Data represent the mean and SD of at least 20 seedlings. Different letters indicate significant differences according to Bonferroni corrected (P < 0.05).
