The COP1-SPA complex acts as a positive regulator as well as acts as negative regulator by shown in statements;
a) Act as negative regulator−that targets transcription factors for degradation during phytochrome and cryptochrome responses
b) Acts as a positive regulator−that targets transcription factors for degradation during phytochrome and cryptochrome responses
c) Acts as a negative regulator− during UV-B signaling by interacting with the C-terminal region of UVR8 in the nucleus UVR8- COP1-SPA complex then activates the major transcription factor HY5, which controls the expression of many of the genes induced by UV-B
d) Acts as a positive regulator during UV-B signaling by interacting with the C-terminal region of UVR8 in the nucleus UVR8- COP1-SPA complex then activates the major transcription factor HY5, which controls the expression of many of the genes induced by UV-B
Whichof the following combination from avbove statements of UVR8 is true?
