Experiment was performed to assess the effect of Arabidopsis H1 histones knock-out on DNA methylation under control conditions and a role of H1.3 in maintaining stress-induced menthylation response.
Exposure of plants to stress conditions or to certain chemical elicitors can establish a primed state, whereby responses to future stress encounters are enhanced. Stress priming can be long-lasting an
DNA methylation in plant genomes occurs in different sequence and genomic contexts that have very different properties. DNA methylation that occurs in CG (mCG) sequence context shows transgenerational
