What happens when Pfr moves to the nucleus?

#Unit 6. System Physiology – Plant

Binds to the G-BOX elements of LHCB gene promoter these LHCB transcription factors in turn activate the transcription of other genes, such as MYB
Binds to a monomer of the transcription factor, PIF3 and activate the transcription of genes, such as LHCB
Binds to a dimer of the transcription factor, PIF3, which is bound to the G-BOX elements of MYB gene promoter, these MYB transcription factors in turn activate the transcription of other genes, such as LHCB
Initiate the transcription of the MYB gene by binding LHCB complex with PIC and TATA
