TranscriptomicsA SWI/SNF nucleosome remodeling complex acts in non-coding RNA-mediated transcriptional silencing
RNA-mediated transcriptional silencing prevents deleterious effects of transposon activity and controls the expression of protein-coding genes. It involves long non-coding RNAs (lncRNAs)1, which in Arabidopsis thaliana are produced by a specialized RNA Polymerase V (Pol V)2. lncRNAs guide Argonaute-...

GenomicsRNA polymerase V targets transcriptional silencing components to promoters of protein-coding genes
Transcriptional gene silencing controls transposons and other repetitive elements through RNA-directed DNA methylation (RdDM) and heterochromatin formation. A key component of the Arabidopsis RdDM pathway is ARGONAUTE4 (AGO4), which associates with sizs to mediate DNA methylation. Here, we show that...

TranscriptomicsLong non-coding RNA produced by RNA polymerase V determines boundaries of heterochromatin
We report genome-wide detection of long noncoding RNA (lncRNA) generate by Pol V in transcriptional gene silencing in Arabidopsis thaliana. We further show that most of these transcripts are bound by AGO4. RNA immunoprecipitation followed by high-throughput sequencing (RIP-seq) RNA immunoprecipitati...
