''FLC'' è espresso nelle giovani piante sin dalla [[gametogenesi]] e impedisceinibisce la fioritura. Dopo aver attraversato un periodo freddo, l'espressione di ''FLC'' viene inibita e, di conseguenza, la pianta differenzia i tessuti fiorali<ref>{{citation | doi = 10.1073/pnas.060023597 | year = 2000 | month = Mar | author = Sheldon, Cc; Rouse, Dt; Finnegan, Ej; Peacock, Wj; Dennis, Es | title = The molecular basis of vernalization: the central role of FLOWERING LOCUS C (FLC). | volume = 97 | issue = 7 | pages = 3753–8 | pmid = 10716723 | pmc = 16312 | journal = Proceedings of the National Academy of Sciences of the United States of America | url = http://www.pnas.org/cgi/pmidlookup?view=long&pmid=10716723 | format = Free full text }}</ref>.
