Plants have evolved with multiple photoreceptors, Phytochrome is one of them. Which of the following statements is incorrect about these photoreceptors?

#SCPH05 I Biotechnology

Phytochrome in the functionally active dimeric form with a molecular mass of about 250 kDa
phytochrome chromophore is a linear tetrapyrrole and absorbed light called phytochromobilin
Phytochromobilin is exported to the cytosol where it autocatalytically attaches to the PHY apoprotein through a thioether linkage to a cysteine residue
Phytochromobilin undergoes to the cis and trans isomerisation with its pyrrole ring around C-12 and C-13 after absorbing light
