Higher interactive complexity between histone marks in Arabidopsis

In eukaryotes, epigenetic modifications of histones are one of the many mechanisms allowing the dynamic control of DNA accessibility. These modifications are multiple and occur in a precise and hierarchical order during the transcription of genes into mRNA in animal cells. The team of Wen-Hui Shen, in collaboration with the team of Meike Van Lijsebettens (VIB, Ghent, Belgium), demonstrated that this order was much less strict in Arabidopsis and that a certain flexibility could exist in the interdependence between different histone modifications. This study is published in the journal New Phytologist.
