Protein function
Encodes a zinc finger transcription factor.
Phenotype
Multiple mutant: cdf1;
cdf2;
cdf3;
cdf5 quadruple mutant is early flowering under both SD and LD conditions, with additive effects. ( In this multiple mutant,
CDF1 is downregulated by RNAi while other
cdf mutants are null mutants.)
[Fornara et al., 2009] Single mutant: cdf3 single mutant is early flowering under SD conditions only.
[Fornara et al., 2009] Remarks: GI acts through CDFs to regulate the expression of
CO and
FT, but CDFs are also involved in the regulation of additional processes which are not related to the control of flowering-time. GI also has CDF-independent functions - e.g. in the circadian clock.
[Fornara et al., 2015] Remarks: The overexpression of
CDF3 leads to conflicting results: Imaizumi et al. (2005) did not observe a flowering-time phenotype while Fornara et al. (2009) observed an early flowering-time phenotype in LD when
CDF3 is overexpressed in the vasculature (
SUC2 promoter).
[Fornara et al., 2009][Imaizumi et al., 2005] Function:Transcription factor that binds specifically to a 5 -AA[AG]G-3 consensus core sequence (By similarity). Regulates a photoperiodic flowering response. Transcriptional repressor of CONSTANS expression.
