<FLOWERING LOCUS C>, or <FLC>, encodes a floral repressor in <Arabidopsis thaliana>. Prolonged cold can establish a persistently silenced state, connecting <chromatin> regulation to the memory underlying <vernalization>.
Natural variation in <FLC> silencing contributes to differences in cold requirements. Measuring later <flowering> and the persistence of repression tests memory, whereas measuring expression only during cold does not establish that the regulatory change survives warming.<Variation in the epigenetic silencing of FLC contributes to natural variation in Arabidopsis vernalization response by Chikako Shindo and others>[2006, abstract and natural variation]{ref}
