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 ). Witryna11 kwi 2014 · Working in Arabidopsis, Costa et al. (p. 168; see the Perspective by Bayer) identified a trio of small signaling peptides that derive from the endosperm but that regulate growth of the embryo. RNA interference was used to down-regulate expression of all three peptides. Fertilization was not affected, but seed growth was. imq activa
