TranscriptomicsTranscriptional gene silencing mediated by interplay of MOM1 and Pol V
In plants, multiple levels of epigenetic control suppress transposon movement and permit somatic as well as transgenerational transmission of gene expression patterns. A variety of factors are involved that establish and/or maintain epigenetic marks, such as covalent modification of DNA and histones...

TranscriptomicsLoss of DNA methylation affects recombination landscape in Arabidopsis
During sexual reproduction half of the genetic material is deposited in gametes and a complete set of chromosomes is restored upon fertilisation. Reduction of the genetic information prior gametogenesis occurs in meiosis where crossovers (COs) between homologous chromosomes secure an exchange of the...

TranscriptomicsStress-induced activation of heterochromatic transcription
Constitutive heterochromatin comprising the centromeric and telomeric parts of chromosomes includes DNA marked by high levels of methylation associated with histones modified by repressive marks. These epigenetic modifications silence transcription and ensure stable inheritance of this inert state. ...
