RNA-mediated in vivo Directed Evolution in Yeast
Bio-Protocol, 2022 Directed evolution is a powerful approach to obtain genetically-encoded sought-for traits. Compared to the prolonged adaptation regimes to mutations occurring under natural selection, directed evolution unlocks rapid screening and selection of mutants ...

eLife, 2022 In plants, selfish genetic elements, including retrotransposons and DNA viruses, are transcriptionally silenced by RNA-directed DNA methylation. Guiding the process are short interfering RNAs (siRNAs) cut by DICER-LIKE 3 (DCL3) from double-stranded ...

SHH1, a homeodomain protein required for DNA methylation, as well as RDR2, RDM4, and chromatin remodeling factors, associate with RNA polymerase IV. [PDF]
PLoS Genetics, 2011 DNA methylation is an evolutionarily conserved epigenetic modification that is critical for gene silencing and the maintenance of genome integrity. In Arabidopsis thaliana, the de novo DNA methyltransferase, domains rearranged methyltransferase 2 (DRM2),

Metal A and metal B sites of nuclear RNA polymerases Pol IV and Pol V are required for siRNA-dependent DNA methylation and gene silencing. [PDF]
PLoS ONE, 2009 Plants are unique among eukaryotes in having five multi-subunit nuclear RNA polymerases: the ubiquitous RNA polymerases I, II and III plus two plant-specific activities, nuclear RNA polymerases IV and V (previously known as Polymerases IVa and IVb).

Dynamic regulation of ARGONAUTE4 within multiple nuclear bodies in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2008 DNA methylation directed by 24-nucleotide small RNAs involves the small RNA-binding protein ARGONAUTE4 (AGO4), and it was previously shown that AGO4 localizes to nucleolus-adjacent Cajal bodies, sites of snRNP complex maturation. Here we demonstrate that

The Rise and Fall of Billionaire siRNAs during Reproductive Development in Rice
Plants, 2022 RNA polymerase IV-dependent siRNAs, usually 24 nt in length, function in the RNA-directed DNA methylation that is responsible for de novo methylation in plants.

New link between the RNA polymerase II-CTD and replication stress
Molecular & Cellular Oncology, 2021 Conflicts between transcription and replication are a major source of replication stress. Our recent findings show that proper dephosphorylation of Serine 5 in the carboxy-terminal domain (CTD) of DNA-directed RNA polymerase II subunit RPB1 is needed to ...

Production and processing of siRNA precursor transcripts from the highly repetitive maize genome. [PDF]
PLoS Genetics, 2009 Mutations affecting the maintenance of heritable epigenetic states in maize identify multiple RNA-directed DNA methylation (RdDM) factors including RMR1, a novel member of a plant-specific clade of Snf2-related proteins.
