COP1 Genetically Acts Downstream of CRY1, CRY2, phyA, and phyB.
(A) Confocal images of the cotyledon epidermis of cry1 cry2, cop1-5, and cry1 cry2 cop1-5 seedlings grown under blue light (30 μmol·m−2·s−1) for 10 d.
(B) Confocal images of the cotyledon epidermis of phyB, cop1-5, and phyB cop1-5 seedlings grown under red light (50 μmol·m−2·s−1) for 10 d.
(C) Confocal images of the cotyledon epidermis of phyA, cop1-5, and phyA cop1-5 seedlings grown under far-red light (12 μmol·m−2·s−1) for 10 d. Cell shapes were visualized by staining by PI. Bars = 20 μm.
