Is DNA methylation modulated by wounding-induced oxidative burst in maize?
Plants respond to environmental changes by modifying gene expression. One of the mechanisms regulating gene expression is methylation of cytosine to 5-methylcytosine (m(5)C) which modulates gene expression by changing chromatin structure. Methylation/demethylation processes affect genes that are controlled upon environmental stresses. Here, on account of the regulatory role of m(5)C, we evaluat...

wall carbohydrates, and organic acids. The hydroxycinnamic acid amides with tyramine and octopamine are also common types of conjugates.2) The formation of the amides serves a defensive purpose in solanaceous plants such as potato,3・4) tobacco5) and tomato.6) Various forms of stress, including physical injury, infection with pathogens and elicitor-treatments, induce the accumulation of hydroxyc...
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 کاملAttenuation of the oxidative burst-induced DNA damage in human leukocytes by hyaluronan.
Oxidative burst provides the mechanism for specialized phagocytes, such as granulocytes or monocytes, to kill invading microorganisms through generation of superoxide anions. However, the oxidants generated during the burst damage DNA of the phagocytes and neighboring cells. Human blood leukocytes treated with phorbol myristate acetate (PMA) are considered to represent the experimental model of...
