Methylcytosine oxidation derivatives are preferentially associated with repetitive chromatin and mark active rDNA in Silene latifolia
Introduction DNA methylation and its oxidative derivatives are key components of epigenetic regulation, yet their roles in plant repetitive DNA remain poorly understood. Here, we investigate the genomic distribution of oxidized cytosine modifications: 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxy...
