In a paper published online in advance in Nucleic Acids Research this week, investigators in France present "genome-wide evidence for local DNA methylation spreading from small RNA-targeted sequences in Arabidopsis." By re-annotating transposable element sequences in the plant with an eye toward analyzing genome-wide DNA methylation at single-nucleotide resolution, the team found that "although the majority of TE sequences are methylated, [about] 26 percent are not."
