Examining the Causes and Consequences of Context-Specific Differential DNA Methylation in Maize.
DNA methylation is a stable modification of chromatin that can contribute to epigenetic variation through the regulation of genes or transposons. Profiling of DNA methylation in five maize (Zea mays) inbred lines found that while DNA methylation levels for more than 99% of the analyzed genomic regions are similar, there are still 5,000 to 20,000 context-specific differentially methylated region...
متن کاملHeritable Epigenetic Variation among Maize Inbreds
Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. ...
متن کاملAssociation study between DNA methylation and genetic variation of APOE gene with the risk of coronary artery disease
Coronary artery disease (CAD) is a common health problem with a high rate of disability and death. Dyslipidemia and altered metabolism of Apo-lipoproteins are involved in the CAD pathogenesis. The current study investigated two common polymorphisms (rs429358 and rs7412) and promoter DNA methylation status of APOE in the Iranian CAD patients and control subjects. Two hundred angiographi...
متن کاملConsistent and heritable alterations of DNA methylation are induced by tissue culture in maize.
Plants regenerated from tissue culture and their progenies are expected to be identical clones, but often display heritable molecular and phenotypic variation. We characterized DNA methylation patterns in callus, primary regenerants, and regenerant-derived progenies of maize using immunoprecipitation of methylated DNA (meDIP) to assess the genome-wide frequency, pattern, and heritability of DNA...
متن کاملEpigenetic variation, inheritance, and parent-of-origin effects of cytosine methylation in maize (Zea mays).
Pure epigenetic variation, or epigenetic variation that is independent of genetic context, may provide a mechanism for phenotypic variation in the absence of DNA mutations. To estimate the extent of pure epigenetic variation within and across generations and to identify the DNA regions targeted, a group of eight plants derived from a highly inbred line of maize (Zea mays) was analyzed by the me...
