Leaf excision prevents damping of PHYA and CAB expression in the dark. Seedlings were germinated and grown for 3 weeks under 12-h light/12-h dark cycles. Leaves were excised (black symbols) or collars were placed around the leaves of intact plants (white symbols) 6 h before the luminescence assays began. Top left, PHYA:LUC luminescence in constant dark. Bottom left, CAB2:LUC luminescence in constant dark. Top right, PHYA:LUC luminescence in constant RL. Bottom right, CAB2:LUC luminescence in constant RL.
