(Submitter supplied) Amino-terminal tails of histones are targets for diverse post-translational modifications whose combinatorial action may constitute a code that will be read and interpreted by cellular proteins to define particular transcriptional states. Here, we describe monomethylation of histone H3 lysine 23 (H3K23me1) as a novel histone modification in plants. H3K23me1 is an evolutionary conserved mark in diverse flowering plant species. more...

(Submitter supplied) Functional genomic states are maintained by reinforcing chromatin interactions that exclude the components of other states. Plant heterochromatin features methylation of histone H3 at lysine 9 (H3K9me) and extensive DNA methylation. However, DNA methylation is also catalyzed by a mostly euchromatic small RNA-directed pathway (RdDM) thought to seek H3K9me. How RdDM is excluded from H3K9me-rich heterochromatin is unclear. more...

(Submitter supplied) Histone phosphorylation plays key roles in stress-induced transcriptional reprogramming in metazoans but its function(s) in land plants has remained relatively unexplored. Here we report that an Arabidopsis mutant defective in At3g03940 and At5g18190, encoding closely related Ser/Thr protein kinases, shows pleiotropic phenotypes including dwarfism and hypersensitivity to osmotic/salt stress. The double mutant has reduced global levels of phosphorylated histone H3 threonine 3 (H3T3ph), which are not enhanced, unlike the response in the wild type, by drought-like treatments. more...

(Submitter supplied) Transcriptional gene silencing (TGS) in Arabidopsis is regulated by two distinct pathways, DNA methylation-dependent and –independent. ddm1 and mom1 mutants are defective in the DNA-dependent and –independent pathway, respectively.

(Submitter supplied) Silencing pathways prevent transposable element (TE) proliferation and help to maintain genome integrity through cell division. Silenced genomic regions can be classified as either euchromatic or heterochromatic, and are targeted by genetically separable epigenetic pathways. In plants, the RNA-directed DNA methylation (RdDM) pathway targets mostly euchromatic regions, while CMT methyltransferases are mainly associated with heterochromatin. more...

(Submitter supplied) Cytosine DNA methylation regulates the expression of eukaryotic genes and transposable elements. Methylation is copied by DNA methyltransferases after DNA replication, which results in faithful transmission of methylation patterns during cell division and, at least in flowering plants, across generations. Trans-generational inheritance is mediated by a small group of cells that includes gametes and their progenitors. more...
