Witryna1 sty 2024 · Although genomic imprinting in plants has long been primarily studied in the context of DNA methylation, allele-specific H3K27me3 enrichment on the maternally derived allele is strongly associated with imprinted PEGs in the endosperm of developing plants, an extraembryonic transient tissue functionally analogous to the … WitrynaGenomic imprinting refers to an epigenetic phenomenon where the activity of an allele depends on its parental origin. Imprinting at individual genes has only been described in mammals and seed plants. We will discuss the role imprinted genes play in seed development and compare the situation in plants with that in mammals.

"Witryna15 lut 2012 · Genomic imprinting is a form of epigenetic inheritance whereby the regulation of a gene or chromosomal region is dependent on the sex of the transmitting parent. During gametogenesis, imprinted regions of DNA are differentially marked in accordance to the sex of the parent, resulting in parent-specific expression. " - Imprinting in plants

One form of epigenetic modification, known as DNA methylation, has attracted particular interest.

WitrynaGenomic imprinting, the differential expression of an autosomal gene that is dependent on its parent of origin, has independently evolved in flowering plants and mammals. In both of these organism classes, imprinting occurs in embryo-nourishing tissues-the placenta and the endosperm, respectively.
