DEMETER, Goddess of the harvest, activates maternal MEDEA to produce the perfect seed.
Parental imprinting regulates processes as diverse as mammalian development and seed size in crop plants. In Arabidopsis, the DNA glycosylase DEMETER regulates early seed development, through activation of the maternal copy of the imprinted MEDEA Polycomb gene. Paternal silencing of MEA appears to be a default condition.
