Protein function
Encodes a component of the circadian clock.
Phenotype
Overexpressor: GI overexpressor is early flowering under both SD and LD conditions. ( The flowering-time phenotype is much stronger under SD conditions.)
[Fornara et al., 2009][Mizoguchi et al., 2005][Sawa et al., 2011] Single mutant: gi single mutant is late flowering under LD conditions only. ( Some
gi mutant lines seems to be slightly late flowering under SD conditions as well.)
[Fornara et al., 2009][Sawa et al., 2007][Fowler et al., 1999][Mizoguchi et al., 2005][Sawa et al., 2011] Function:Involved in regulation of circadian rhythm and photoperiodic flowering. May play a role in maintenance of circadian amplitude and period length. Is involved in phytochrome B signaling. Stabilizes ADO3 and the circadian photoreceptor ADO1/ZTL. Regulates CONSTANS (CO) in the long-day flowering pathway by modulating the ADO3-dependent protein stability of CDF1 and CDF2, but is not essential to activate CO transcription. Regulates, via the microRNA miR172, a CO-independent pathway that promotes photoperiodic flowering by inducing FLOWERING LOCUS T .
