title: Epigenetics: the flowers that come in from the cold.
abstract: Plants can remember periods of cold several weeks later and respond by switching from vegetative to reproductive development. Recent findings shed light on this phenomenon by showing that a gene responsible for keeping this memory encodes a member of the Polycomb group of proteins.
