Chloroplast DNA methylation in the kelp Saccharina latissima is determined by origin and possibly influenced by cultivation
Abstract DNA cytosine methylation is an important epigenetic mechanism in genomic DNA. In most land plants, it is absent in the chloroplast DNA. We detected methylation in the chloroplast DNA of the kelp Saccharina latissima , a non‐model macroalgal species of high ecological and economic importance...
