(A) The percentage of transposons/pseudogenes in the Arabidopsis genome for which mRNA-seq-based evidence of transcription was present or absent in each genotype.
(B) Hypermethylation of transposons in rdd. Browser visualization of methylcytosines located within and proximal to the copia-like retrotransposon At2g24660. Dense methylation is present within the retrotransposon only in rdd.
(C) An upregulated intergenic transcript identified in the DNA methyltransferase mutant met1 (indicated by arrow). Sites of DNA methylation are shown, and the color reflects the methylation context, as indicated.
