transcriptional gene silencing

Hydrogen-atom transfer in DNA base pairs (6)

Mobile small RNAs regulate genome-wide DNA methylation Abstract excerpt: RNA silencing at the transcriptional and posttranscriptional levels regulates endogenous gene expression, controls invading transposable elements (TEs), and protects the cell against viruses. Conclusion:  Our conclusions underpin future research into why plants possess a system for communicating methylation status from shoot to root tissues.
