Epigenetic reprogramming events rewire transcription during the alternation of generations in Arabidopsis [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, which is associated with dramatic changes in chromatin accessibility and transcriptional reprogramming. more...
