TL;DR: Considering chromatin-based information, key candidates have arisen as epigenetic marks, including DNA and histone modifications, histone variants, non-histone chromatin proteins, nuclear RNA as well as higher-order chromatin organization.

TL;DR: To accommodate the burgeoning interest of the plant science community in the epigenetic control of plant development, a series of methods used routinely in laboratories have been compiled that can facilitate the characterization of putative chromatin-binding factors at the biochemical, molecular and cellular levels.

TL;DR: In this article, complete removal of CpG methylation in an Arabidopsis mutant null for DNA maintenance methyltransferase results in a clear loss of histone H3 methylation at lysine 9 in heter-chromatin and also at heter-romatic loci that remain transcriptionally silent.

TL;DR: It is shown that pericentric satellites undergo a transient peak in expression precisely at the time of chromocenter formation, and that the exquisite strand-specific expression dynamics at major satellites during the 2-cell stage, with both up and downregulation, are necessary events for proper Chromocenter organization and developmental progression.

TL;DR: It is shown that mutations in Arabidopsis HDA6, a putative class I histone deacetylase gene, result in loss of transcriptional silencing from several repetitive transgenic and endogenous templates, and this control might be functionally linked to silencing of other repetitive templates and to its previously assigned role in RNA-directed DNA methylation.
