Epigenetics: imprinting in plants and mammals--the same but different?
Plants and animals both exhibit parental imprinting, but do they control it the same way? Recent studies show that in Arabidopsis, as in mammals, imprinted alleles are subject to DNA methylation--but, surprisingly, the default state is silence rather than activity.
