Minimal evidence for consistent changes in maize DNA methylation patterns following environmental stress
DNA methylation is a chromatin modification that is sometimes associated with epigenetic regulation of gene expression. As DNA methylation can be reversible at some loci, it is possible that methylation patterns may change within an organism that is subjected to environmental stress. In order to assess the effects of abiotic stress on DNA methylation patterns in maize (Zea mays), seeding plants...
متن کاملDNA methylation patterns in
The frequency of cytosine raethylatlon at specific sites in the somatic 5S DNA (Xls) and trace oocyte 5S DNA (Xlt) of X. laevis has been determined using restriction enzymes that are inhibited by the presence of 5-methylcytosine (S^) within their cleavage sequences. 5S DNA methylation patterns were determined in genomic DNA from mature red blood cells, which express neither type of 5S gene, and...
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 کاملPreclinical and Clinical Evidence of DNA Methylation Changes in Response to Trauma and Chronic Stress
Exposure to chronic stress, either repeated severe acute or moderate sustained stress, is one of the strongest risk factors for the development of psychopathologies such as post-traumatic stress disorder and depression. Chronic stress is linked with several lasting biological consequences, particularly to the stress endocrine system but also affecting intermediate phenotypes such as brain struc...
