Cover Story: Stress-tolerant plants can allow connections to be revealed between specific epigenetic modifications and stress tolerance capacity. The MeDIP-Seq analysis of a salt-tolerant rice variety under salinity revealed a set of differentially methylated regions (DMRs) between control and stress. The DNA methylation patterns of DMRs revealed a general tendency for demethylation events under salt stress conditions. The identification of DMRs represents one step forward to uncover new players in the regulation of stress-responsive genes and new target regions with potential application to enhance plant salinity tolerance.

Most human genes are associated with promoters embedded in non-methylated, G + C-rich CpG islands (CGIs). Not all CGIs are found at annotated promoters, however, raising the possibility that many serve as promoters for transcripts that do not code fo...

EMT (epithelial to mesenchymal transition) is a plastic phenomenon involved in metastasis formation. Its plasticity is conferred in a great part by its epigenetic regulation. It has been reported that the trimethylation of lysine 27 histone H3 (H3K27...
