In Arabidopsis, COP1 is known to interact with transcription factors to regulate photomorphogenesis and skotomorphogenesis under light and dark conditions. Following are certain statements regarding the role of COP1:

A. In darkness, COP1 is active and targets light-responsive transcription factors for degradation, promoting skotomorphogenesis.

B. Under light conditions, COP1 is inactivated, leading to stabilization of light-responsive transcription factors, which induces photomorphogenesis.

C. COP1's inactivation under light results in the promotion of PIF-induced gene transcription, favoring skotomorphogenesis.

D. In darkness, COP1 stabilizes phytochromes, allowing them to activate light-responsive genes.

1
A and B
2
B and C
3
