“…Environmental stresses can induce varying patterns of DNA methylation (Steward et al, 2002;Wada et al, 2004;Verhoeven et al, 2010), the regulation of gene expression may be speculated. In plant development, MSAP (Xiong et al, 1999) was put into use to study genome methylation under stress (Portis et al, 2004;Salmon et al, 2008;Xuelin et al, 2009;Zhong et al, 2009;Yi et al, 2010;Wang et al, 2011;Karan et al, 2012;Albertini and Marconi, 2013;Ou et al, 2015). DNA demethylation often has been related to temperature induction or stress, such as Arabidopsis, maize, Antirrhinum majus and wheat (Steward et al, 2002;Hashida et al, 2003;Sherman and Talbert, 2011).…”

The methylation sensitive amplified polymorphism (MSAP) was used to induce DNA methylation transformation in mushroom mycelia. DNA obtained from the mycelial stages of P. eryngii subsp. tuoliensis was digested with isoschizomers Msp I or Hpa II (mixture of EcoR I), the ability to digest the sequence CpCpGpG as influenced by their methylation state. The data analysis demonstrated that full-methylated and unmethylation modifications were primary and the hemi-methylated ratio was significantly lower. These results indicated that the pattern of CG hypermethylation is abundant in P. eryngii subsp. tuoliensis. All fragments that were differentially amplified upon low temperature induction illustrated the feasibility of MSAP in edible mushrooms. Moreover, this study confirmed that genetic and epigenetic changes in P. eryngii subsp. tuoliensis were induced under low temperature.

“…For instance, treatment of rice seedlings with high concentrations of sodium nitroprusside (SNP, a NO donor) leads to DNA hypomethylation predominantly at the CHG sites, and growth inhibition. In addition, the NO-evoked alterations in DNA methylation can be inherited to the next generation [67]. In another study, application of low concentration of SNP to heat-treated Lablab purpureus plants causes the reduction in the levels of O 2…”

“…Irradiation of the roots markedly decreases the expression of DRM2, and enhances the transcriptional abundances of MET1 and DML3 in bystander aerial plants [80]. Similarly, application of SNP to rice plants induces DNA hypomethylation through down regulation of DNA methyltransferase genes OsCMT2 and OsCMT3 and upregulation of the DNA demethylase gene OsDME [67]. Yet, it is not clear whether the observed DNA hypomethylation in the SNP-treated plants are due to the regulation of DNA methylase activities or due to the NO-mediated post-translational modification of SAMS.…”

“…Mutation of DDM1 leads to a dramatic decrease in DNA methylation in A. thaliana [102]. In rice, exogenous application of SNP results in the downregulation of the expression of OsDDM1a and OsDDM1b, as well as DNA hypomethylation [67], indicating that NO possibly modulates DNA methylation via impacting chromatin remodeling. PICKLE, a CHD3 remodeler, promotes H3K27me3 in A. thaliana [103].…”

Epigenetic modifications including DNA methylation, histone modifications, and chromatin remodeling are crucial regulators of chromatin architecture and gene expression in plants. Their dynamics are significantly influenced by oxidants, such as reactive oxygen species (ROS) and nitric oxide (NO), and antioxidants, like pyridine nucleotides and glutathione in plants. These redox intermediates regulate the activities and expression of many enzymes involved in DNA methylation, histone methylation and acetylation, and chromatin remodeling, consequently controlling plant growth and development, and responses to diverse environmental stresses. In recent years, much progress has been made in understanding the functional mechanisms of epigenetic modifications and the roles of redox mediators in controlling gene expression in plants. However, the integrated view of the mechanisms for redox regulation of the epigenetic marks is limited. In this review, we summarize recent advances on the roles and mechanisms of redox components in regulating multiple epigenetic modifications, with a focus of the functions of ROS, NO, and multiple antioxidants in plants.

Redox-Dependent Chromatin Remodeling: A New Function of Nitric Oxide as Architect of Chromatin Structure in Plants

Nitric oxide (NO) is a key signaling molecule in all kingdoms. In plants, NO is involved in the regulation of various processes of growth and development as well as biotic and abiotic stress response. It mainly acts by modifying protein cysteine or tyrosine residues or by interacting with protein bound transition metals. Thereby, the modification of cysteine residues known as protein S-nitrosation is the predominant mechanism for transduction of NO bioactivity. Histone acetylation on N-terminal lysine residues is a very important epigenetic regulatory mechanism. The transfer of acetyl groups from acetyl-coenzyme A on histone lysine residues is catalyzed by histone acetyltransferases. This modification neutralizes the positive charge of the lysine residue and results in a loose structure of the chromatin accessible for the transcriptional machinery. Histone deacetylases, in contrast, remove the acetyl group of histone tails resulting in condensed chromatin with reduced gene expression activity. In plants, the histone acetylation level is regulated by S-nitrosation. NO inhibits HDA complexes resulting in enhanced histone acetylation and promoting a supportive chromatin state for expression of genes. Moreover, methylation of histone tails and DNA are important epigenetic modifications, too. Interestingly, methyltransferases and demethylases are described as targets for redox molecules in several biological systems suggesting that these types of chromatin modifications are also regulated by NO. In this review article, we will focus on redox-regulation of histone acetylation/methylation and DNA methylation in plants, discuss the consequences on the structural level and give an overview where NO can act to modulate chromatin structure.
