CC   -!- FUNCTION: Involved in regulation of circadian rhythm, and in the
CC       control of the photoperiodic flowering. Acts as a suppressor of
CC       flowering under short-day (SD) and long-day (LD) conditions. Activates
CC       Hd1/CONSTANS gene. {ECO:0000269|PubMed:12700762}.

CC       Name=2;
CC         IsoId=Q9AWL7-2; Sequence=VSP_013910;
CC   -!- INDUCTION: Expressed with a circadian rhythm with the highest level 8
CC       hours into the light and the lowest level at dawn. The peak of
CC       expression in long days is slightly lower, shifted later and the
CC       decrease is slower. {ECO:0000269|PubMed:12040096}.
CC   -!- SIMILARITY: Belongs to the GIGANTEA family. {ECO:0000305}.
