Following statements are regarding to the molecular basis of the coincidence model in Arabidopsis.
A.
In Arabidopsis under short days, there is little overlap between CO mRNA
expression and daylight.
B.
CO protein does not accumulate to sufficient levels in the phloem to promote
the expression of the transmissible floral stimulus and the plant remains vegetative.
C. Under long days, the peak of CO mRNA abundance (at hours 12 through 16) overlaps with daylight (sensed by phyA and cryptochrome [cry]), allowing CO protein to accumulate.
D. CO activates FLC mRNA expression in the phloem, which
causes flowering when the FT protein is translocated to the apical meristem.
Which of the following is incorrect?
