摘要：

It was known that long after far-red light 1 (LAF1), a positive phytochrome A (phyA) signal transducer, is ubiquitinated by constitutive photomorphogenic 1 (COP1) in vitro and stabilizes long hypocotyl in far-red 1 (HFR1), another phyA signal transducer, through direct interaction. Our results imply that LAF1 stabilizes phyA by inhibiting or blocking COP1 activity, or by directly interacting with phyA, resulting in the stimulation of phyA signaling.
