Two recent papers inScience(Jiang and Berger, 2017 and Yang et al., 2017) reveal that an epigenetic mechanism, mediated by polycomb repressor complex 2 (PRC2), induces flowering after prolonged cold. This repression is biphasic, requiring nucleation and propagation; and, strikingly, appears to be intrinsically linked with DNA replication.
