Plant epigenetics: MEDEA's children take centre stage
Schubert D, Goodrich J – 2003
The Arabidopsis Polycomb group gene MEDEA is imprinted in early development and regulates cell proliferation in seeds. A recent study identifies the first direct target of MEDEA regulation. This is an important step towards the genetic manipulation of seed development, and should help clarify the role of Polycomb-group proteins in imprinting in plants.
