Genomic imprinting, methylation and parent-of-origin effects in reciprocal hybrid endosperm of castor bean
Genomic imprinting often results in parent-of-origin specific differential expression of maternally and paternally inherited alleles. In plants, the triploid endosperm is where gene imprinting occurs most often, but aside from studies on Arabidopsis, little is known about gene imprinting in dicotyledons. In this study, we inspected genomic imprinting in castor bean (Ricinus communis) endosperm,...
متن کاملGenome demethylation and imprinting in the endosperm.
Imprinting occurs in the endosperm of flowering plants. The endosperm, a product of central cell fertilization, is critical for embryo and seed development. Imprinting in the endosperm is mainly due to the inherited differences in gamete epigenetic composition. Studies have also shown that there are differences in genomic DNA methylation patterns between embryo and endosperm. Examining those di...
متن کاملGenomic Imprinting
BACKGROUND Genomic imprinting is the inheritance out of Mendelian borders. Many of inherited diseases and human development violates Mendelian law of inheritance, this way of inheriting is studied by epigenetics. AIM The aim of this review is to analyze current opinions and options regarding to this way of inheriting. RESULTS Epigenetics shows that gene expression undergoes changes more com...
متن کاملGenomic imprinting
Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed. If the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated...
متن کاملGenomic imprinting
Genomic imprinting is a normal form of gene regulation that causes a subset of mammalian genes to be expressed from one of the two parental chromosomes. Some imprinted genes are expressed from the maternally inherited chromosomes and others from the paternally inherited chromosomes. This means that the maternal and paternal genomes are not functionally equivalent and is the reason why both a ma...
