Witryna1 lip 2009 · Genomic imprinting is an epigenetic phenomenon in animals and plants that results in the monoallelic expression of specific genes dependent on the parent-of-origin. In plants, imprinting is confined to the endosperm, a terminally differentiated tissue that develops after fertilization of the central cell (Feil and Berger, 2007 ).
