Small RNAs: how seeds remember to obey their mother

Curr Biol. 2009 Aug 11;19(15):R649-51. doi: 10.1016/j.cub.2009.06.049.


The endosperm is one of two products from the double fertilization event that occurs during sexual reproduction in flowering plants. A series of recent reports highlights the unusual genetic regulatory mechanisms that occur in endosperm and suggests a role for transposon regulation in imprinting.
