Both PHYA and PHYB activate the transcription of LHCB gene for its expression, there following events occur during the activation of LHCB gene such as;
a) PhyA, both form is activated Pr and Pfr by phosphorylation Pr form move into the nucleus activate the light-regulated gene expression during degradation of the HY5 by COP1
b) PhyA, Pfr form is activated by phosphorylation and move into the nucleus where it’s export the COP1 out of the nucleus, and activate the light-regulated gene expression
c) Phy B, activated phosphorylated Pfr form is move into the nucleus and binds to a dimer of the transcription factor PIF3, by inibiting PIF3 expression activate the transcription of LHCB gene by intermediate transcriptional factor MYB
d) Phy B, activated unphosphorylated Pfr form is move into the nucleus and binds to a monomer of the transcription factor PIF3, by inibiting PIF3 expression activate the transcription of MYB gene by intermediate transcriptional factor LHCB
Which of the following combination of the above statements of phytochrome forms is correct?
