In previous blog articles, we discussed howplants use epigenetics to remember past heat stress responses, enabling them to self-regulate during intense heat bouts. We have also reported on howplant models experimentally subjected to vinegarpossessed a naturally occurring epigenetic modification that correl...
Changes in the methylome coincide with chromatin accessibility of the embryo genome. Histone modifications facilitate the dynamic change in the chromatin state of preimplantation embryos to allow incorporation of paternal and maternal genomes [38,44,45]. These histone modification changes also occur asymme...
Epigenetic states are stably propagated in eukaryotes. In plants, DNA methylation patterns are faithfully inherited over many generations but it is unknown how the dynamic activities of cytosine DNA methyltransferases and 5-methylcytosine DNA glycosylases interact to maintain epigenetic homeostasis. Here we...
modification are regarded as ChIP-on-chip(chromatin immunoprecipitation-on-chip) and GMAT(genomewide mapping technique).DNA methylation,as a regulatory mechanism of gene expression,also plays an important role in the process of growth and development in plants.The relationship between the degree of ...
RNA-directed DNA methylation (RdDM) is the major small RNA-mediated epigenetic pathway in plants. RdDM requires a specialized transcriptional machinery that comprises two plant-specific RNA polymerases — Pol IV and Pol V — and a growing number of accessory proteins, the functions of which in th...
article [1] is the first to integrate game theory (especially evolutionary game theory) with epigenetic modification of zygotic genomes. They described and assessed a modeling framework based on evolutionary game theory to quantify, how sperms and oocytes interact through epigenetic processes, to ...
