Transcriptional gene silencing is a pivotal mechanism for regulating gene expression and genome stability. In Arabidopsis, combined analyses of small RNAs (sRNAs) and DNA methylation reveals that mobile 24-nt sRNAs are involved in reinforcing genome-wide silencing of transposons through DNA methylation.
