No Winter Lasts Forever: Polycomb Complexes Convert Epigenetic Memory of Cold into Flowering

Publication date: 25 September 2017
Source:Developmental Cell, Volume 42, Issue 6
Author(s): Jafar Sharif, Haruhiko Koseki
Two recent papers in Science (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.
