This webinar discusses a project that sought to understand the parent-of-origin epigenetic mechanisms that regulate seed development in plants, with a particular emphasis on differentiating the maternal or paternal origin of epigenetics marks. Parental-specific epigenetic marks are established in the gametes and maintained after fertilization, resulting in parental epigenetic asymmetry. Epigenetic asymmetry causes parent-of-origin-specific gene expression, a phenomenon termed genomic imprinting. Imprinted genes play an important role in animal and plant development.
