PP6 negatively regulated photomorphogenesis. Phenotypes (A) and hypocotyl lengths (B) of wild-type (Col-0), f1, f3, f1 f3, pifq, and pifq f1 f3 mutants grown in the dark for 4 d. Phenotypes (C) and hypocotyl lengths (D) of Col-0, f1, f3, f1 f3, pifq, and pifq f1 f3 mutants grown under continuous red light (30 μmol⋅m⁻²⋅s⁻¹) for 4 d. Data are shown as mean ± SD (n ≥ 20). **P < 0.01, as calculated by Student’s t test. The experiments were performed 3 times, with similar results each time.
