DNA methylation-free Arabidopsis reveals crucial roles of DNA methylation in regulating gene expression and plant development

(Submitter supplied) A contribution of DNA methylation to defense against invading nucleic acids and maintenance of genome integrity is uncontested; however, the relevance of this epigenetic mark for genome-wide gene regulation and plant development is unclear. Here, we knocked out all five known DNA methyltransferases in Arabidopsis, generating DNA methylation-free plants. This quintuple mutant exhibits a suite of unique and extreme developmental defects, unequivocally demonstrating that DNA methylation is essential for normal plant development. more...

DNA Methylation shapes histone modification landscape for transcription regulation in Arabidopsis [WGBS]

(Submitter supplied) DNA methylation and histone modifications cooperate to shape the epigenetic landscape for transcription regulation, but their orchestration is not fully understood due to the lack of met1 drm1 drm2 cmt2 cmt3 mutants (mddcc), in which total DNA methylation were eliminated. This is the first time to generate mddcc that allow us to elucidate the roles of DNA methylation in the upheaval of histone modification landscape, transposon activity and gene expression. more...

Epigenetic reprogramming events rewire transcription during the alternation of generations in Arabidopsis [Small RNA-Seq]

(Submitter supplied) Alternation between morphologically distinct haploid and diploid life forms is a defining feature of most plant and algal life cycles, yet the underlying molecular mechanisms that govern these transitions remain unclear. Here, we explore the dynamic relationship between chromatin accessibility and epigenetic modifications during life form transitions in Arabidopsis. The diploid-to-haploid life form transition is governed by the loss of H3K9me2 and DNA demethylation of transposon-associated cis-regulatory elements. more...

H3K23me1 is an evolutionary conserved histone modification associated with CG DNA methylation in Arabidopsis

(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...
