Contribution of epigenetic variation to adaptation in Arabidopsis. [PDF]
Nat Commun, 2018 AbstractIn plants, transgenerational inheritance of some epialleles has been demonstrated but it remains controversial whether epigenetic variation is subject to selection and contributes to adaptation. Simulating selection in a rapidly changing environment, we compare phenotypic traits and epigenetic variation between Arabidopsis thaliana populations ...

Heritable epigenetic variation among maize inbreds. [PDF]
PLoS Genetics, 2011 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 ...

Worldwide patterns of human epigenetic variation. [PDF]
Nat Ecol Evol, 2017 Abstract DNA methylation is an epigenetic modification, influenced by both genetic and environmental variation, that can affect transcription and many organismal phenotypes. Although patterns of DNA methylation have been shown to differ between human populations, it remains to be determined whether epigenetic diversity mirrors the ...

Exploring and exploiting epigenetic variation in crops.
Genome, 2011 This review addresses the mechanisms by which epigenetic variation modulates plant gene regulation and phenotype. In particular we explore the scope for harnessing such processes within the context of crop genetic improvement. We focus on the role of DNA methylation as an epigenetic mark that contributes to epiallelic diversity and modulation of gene ...

Epigenetic natural variation in Arabidopsis thaliana. [PDF]
PLoS Biology, 2007 Cytosine methylation of repetitive sequences is widespread in plant genomes, occurring in both symmetric (CpG and CpNpG) as well as asymmetric sequence contexts.

Epigenetic variation: origin and transgenerational inheritance
Current Opinion in Plant Biology, 2012 Recent studies have revealed that epigenetic variation in plant populations exceeds genetic diversity and that it is influenced by the environment. Nevertheless, epigenetic differences are not entirely independent of shared ancestry. Epigenetic modifications have gained increasing attention, because one can now study their patterns across the entire ...

Epigenetic Variation, Inheritance, and Selection in Plant Populations [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2012 Plant populations show phenotypic diversity, which may be caused by genetic and epigenetic variation. It has recently been shown that new epigenetic variants are generated at a higher rate than genetic variants and several studies have shown that epigenetic variation can be influenced by the environment.

Genetic variation stimulated by epigenetic modification. [PDF]
PLoS ONE, 2008 Homologous recombination is essential for maintaining genomic integrity. A common repair mechanism, it uses a homologous or homeologous donor as a template for repair of a damaged target gene.

Epigenetics and phenotypic variation in mammals [PDF]
Mammalian Genome, 2006 What causes phenotypic variation? By now it is clear that phenotype is a result of the interaction between genotype and environment, in addition to variation not readily attributable to either. Epigenetic phenomena associated with phenotypic variation at the biochemical, cellular, tissue, and organism level are now well recognized and are likely to ...

Exploiting Epigenetic Variations for Crop Disease Resistance Improvement
Frontiers in Plant Science, 2021 Pathogen infections seriously threaten plant health and global crop production. Epigenetic processes such as DNA methylation, histone post-translational modifications, chromatin assembly and remodeling play important roles in transcriptional regulation ...
