Small interfering RNAs (siRNAs) are responsible for establishing and maintaining DNA methylation through the RNA‐directed DNA methylation (RdDM) pathway in plants. Although siRNA biogenesis is well known, it is relatively unclear about how the process is regulated. By a forward genetic screen in Arabidopsis thaliana, we identified a mutant defective in NOT1 and demonstrated that NOT1 is required for...
RNA-directed DNA methylation (RdDM) is responsible for transcriptional silencing of endogenous transposable elements and introduced transgenes. This process requires non-coding RNAs produced by DNA-dependent RNA polymerases IV and V (Pol IV and Pol V). Pol IV-produced non-coding RNAs are precursors of 24-nt small interfering RNAs, whereas Pol V-produced ncRNAs directly act as scaffold RNAs. In this...
