Mechanisms and evolution of genomic imprinting in plants

Witryna26 lut 2024 · Genomic imprinting is an epigenetic phenomenon that differentiates maternal and paternal copies of genes in the genome and causes monoallelic expression depending on parental origin. Imprinting is an evolutionary puzzle, as it bears the costs of diploidization without its advantages, namely, protection from recessive mutations. Witryna11 mar 2024 · In plants, the establishment of DNA methylation is mediated by the RNA-directed DNA methylation (RdDM) pathway, where the DNA methyltransferase DOMAINS REARRANGED METHYLTRANSFERASE 2 (DRM2) catalyzes de novo DNA methylation in all sequence contexts (Zhang et al., 2024) (Fig. 1a ). Witryna12 cze 2009 · 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. florist oxton wirral
