Imprinting in plants

Witryna14 lip 2024 Ā· Epigenetic phenomena such as paramutation, transgenic silencing, imprinting, and transposable element inactivation are prevalent in plants and potentially offer an untapped molecular resource for directed crop improvement. One form of epigenetic modification, known as DNA methylation, has attracted particular interest.

The mark appears to be methylation of the DNA in the promoter (s) of the gene. Methyl groups are added to cytosines (Cs) in the DNA. floplast sp103 dimensionsWitryna15 lut 2012 Ā· 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. floplast air admittance valveWitryna12 cze 2009 Ā· In plants, imprinting occurs in the endosperm, which nourishes the embryo during seed development. We have profiled Arabidopsis DNA methylation genome-wide in the embryo and endosperm and found that large-scale methylation changes accompany endosperm development and endosperm-specific gene expression. floplast rodding eye
