Genomic imprinting is an epigenetic phenomenon of differential allelic expression based on parental origin. To date, 263 imprinted genes have been identified among all investigated mammalian species.
We report that rice endosperm shows a specific hypomethylation of DNA in the maternal genome, preferring regions of high DNA accessibility. Maternally expressed imprinted genes are enriched for hypome
Uniparental reproduction is widespread among lower vertebrates, but not in mammals. Researchers have produced bimaternal mice with a deletion of the H19 imprinted region. However, the mechanism of a s
