High impact information on FY

The FCA/FY interaction is also required for the downregulation of the floral repressor FLC [1].
FCA and FY function to control polyadenylation site choice during processing of the FCA transcript [2].
The late-flowering fy alleles are hypomorphic and indicate a requirement for both intact FY WD repeats and the C-terminal domain in repression of FLC [2].

Biological context of FY

Within this pathway FCA is a plant-specific, nuclear RNA-binding protein, which interacts with FY, a highly conserved eukaryotic polyadenylation factor [2].
