Abstract excerpt
Genomic imprinting resulting in the differential expression of maternal and paternal alleles in the fertilization products has evolved independently in placental mammals and flowering plants. In most cases, silenced alleles carry DNA methylation. Whereas these methylation marks of imprinted genes are generally erased and reestablished in each generation in mammals, imprinting marks persist in endosperms, the sole...
