DNA methylation is an epigenetic modification required for transposable element (TE) silencing, genome stability, and genomic imprinting. Although DNA methylation has been intensively studied, the dynamic nature of methylation among different species has just begun to be understood. Here we summarize the recent progress in research on the wide variation of DNA methylation in different plants, organs, tissues, and cells; dynamic changes of methylation are also reported during plant growth and development as well as changes in response to environmental stresses. Overall DNA methylation is quite diverse among species, and it occurs in CG, CHG, and CHH (H = A, C, or T) contexts of genes and TEs in angiosperms. Moderately expressed genes are most likely methylated in gene bodies. Methylation levels decrease significantly just upstream of the transcription start site and around transcription termination sites; its levels in the promoter are inversely correlated with the expression of some genes in plants. Methylation can be altered by different environmental stimuli such as pathogens and abiotic stresses. It is likely that methylation existed in the common eukaryotic ancestor before fungi, plants and animals diverged during evolution. In summary, DNA methylation patterns in angiosperms are complex, dynamic, and an integral part of genome diversity after millions of years of evolution.

The key transcription factors of T helper cell subpopulations, including T-bet, GATA3, RORγt, and Foxp3 are involved in various autoimmune diseases. Whether methylation of these master transcription factors is associated with the development of experimental autoimmune uveitis (EAU) and the possible epigenetic regulatory mechanisms involved has however not yet been addressed. In our study, significant methylation changes in both Tbx21 and Rorc were observed in one CpG site in the retinas of EAU mice. Two CpG sites of Tbx21 and one CpG site of Rorc showed significant dynamic methylation changes in the RPE-choroid complex during EAU. The mRNA expressions of Tbx21 and Rorc in both the retinas and RPE-choroid complexes correlated with the methylation changes at the various time points during EAU development. The methylation changes were associated with the production of the Th1/Th17 cells’ signature cytokines, IFN-γ and IL-17. Dynamic changes in mRNA expression of DNA methyltransferases (DNMT1) were also noted, which may be related to the observed methylation changes of these genes. The present study provides evidence that DNA methylation of Tbx21 and Rorc may be associated with the development of EAU. DNMT1 activation may have an important effect on regulating DNA methylation dynamics.
