genomic imprinting epigenetic programming in the central cell https://github.com/geneontology/go-ontology/issues/25455 The establishment of epigenetic modifications (imprints) in a plant central cell, leading to an asymmetry between the two maternal alleles and the paternal allele, and differential expression of the corresponding alleles in the developing endosperm. This can happen through heterochromatin formation or differential chromatin loop formation. 2023-06-09T12:27:08Z biological_process GO:0141063 pg
