Protein function
Encodes a protein involved in RNA-mediated chromatin silencing.
Phenotype
Single mutant: fca single mutant is late flowering under both SD and LD conditions.
[Reeves et al., 2002][Martü¾™†”¼nez-Zapater et al., 1990][Sheldon et al., 2000][Macknight et al., 1997] Remarks: FCA acts together with FPA to prevent the expression of distally polyadenylated antisense RNAs from the
FLC locus.
[Michaels et al., 2001][Duc et al., 2013] Remarks: FCA requires FY and FLD to repress the expression of
FLC through H3K4 demethylation. Its function also relies partially on DCL3.
[Liu et al., 2007] Overexpressor: The overexpression of
FCA leads to a slight but reproducible early-flowering phenotype under both SD and LD conditions.
[Macknight et al., 2002][Macknight et al., 1997] Function:Plays a major role in the promotion of the transition of the vegetative meristem to reproductive development. Plays a role in the regulation of flowering time in the autonomous flowering pathway by decreasing FLOWERING LOCUS C mRNA levels. Required for RNA-mediated chromatin silencing of a range of loci in the genome. Cotranscriptionally recognizes aberrant RNA and marks it for silencing. Controls alternative cleavage and polyadenylation on pre-mRNAs and antisense RNAs. Acts redundantly with FPA to prevent the expression of distally polyadenylated antisense RNAs at the FLC locus.
