Flowering Locus C : ウィキペディア英語版 | Flowering Locus C Flowering Locus C (''FLC'') is a MADS-box gene that in late-flowering ecotypes of the plant ''Arabidopsis thaliana'' is responsible for vernalization. In a new seedling ''FLC'' is expressed, which prevents flowering. Upon exposure to cold, less ''FLC'' is expressed (to a degree depending on the amount of cold), and flowering becomes possible. ''FLC'' is extensively regulated through epigenetic modifications and transcriptional control. The expression of ''FLC'' is affected by other genes including ''FLK'', ''FCA''〔 and ''VERNALIZATION2'' (''VRN2''). Wild ''Arabidopsis'' plants have different alleles for the ''FLC'' gene, which correspond to ecotypes which either (a) flower rapidly and produce a number of generations during one summer (''summer-annual''), or (b) flower only after vernalization (''winter-annual'' or ''late-flowering''). This kind of variation can also be provided by variation in the ''FRIGIDA'' (''FRI'') gene. == References == 〔
