Witryna15 mar 2008 · In flowering plants, imprinting has only been detected in the endosperm, a terminal tissue that develops after fertilization of the central cell. In dicot species like Arabidopsis, the endosperm nourishes the embryo during its growth phase and is almost completely consumed during embryo development ( Berger, 2003 ).

Witryna21 cze 2024 · Here, we employ single-nucleus RNA-sequencing to generate a transcriptional atlas of developing Arabidopsis thaliana seeds, with a focus on endosperm. Endosperm, the primary site of gene imprinting in flowering plants, mediates the relationship between the maternal parent and the embryo 2. 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 ).
