摘要:
The seed-specific transcription factor LEC1 promotes an active chromatin state at the floral repressor FLC and activates its expression in the Arabidopsis pro-embryo, thus reversing the winter cold-induced silenced state that is inherited from gametes. In the plant Arabidopsis thaliana, prolonged exposure to the cold in winter triggers the epigenetic silencing of the floral repressor FLOWERING LOCUS C (FLC), enabling plants to flower in spring. However, this stable silenced or 'vernalized' state must be reset in each generation. Here, Yuehui He...
