LHP1, the Arabidopsis homologue of HETEROCHROMATIN PROTEIN1, is required for epigenetic silencing of FLC.

Abstract

Vernalization is the acceleration of flowering by prolonged cold that aligns the onset of reproductive development with spring conditions. A key step of vernalization in Arabidopsis is the epigenetic silencing of FLOWERING LOCUS C (FLC), which encodes a repressor of flowering. The vernalization-induced epigenetic silencing of FLC is associated with histone… (More)
