Protein function

Encodes a mRNA processing factor that regulates FCA expression.

Phenotype

Overexpressor:
FY overexpression complements fy mutation but does not display any flowering-time phenotype. [Simpson et al., 2003][Jiang et al., 2012]

Remarks:
fy single mutant has increased FLC expression levels. [Simpson et al., 2003][Manzano et al., 2009]

Single mutant:
fy single mutant is late flowering under both SD and LD conditions. (Characterized mutants are hypomorphics, since the null mutant is lethal.) [Simpson et al., 2003][Henderson et al., 2005][Koornneef et al., 1991]

Function:
Plays a role in the regulation of flowering time in the autonomous flowering pathway by decreasing FLOWERING LOCUS C mRNA levels. Required for the negative autoregulation of FCA expression. Acts probably as an RNA 3 end-processing factor. Required for growth and development in plants. [Data from UniProt]
