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.

The ability to form homodimers is essential for RDM1 to function in RNA-directed DNA methylation. [PDF]
PLoS ONE, 2014 RDM1 (RNA-DIRECTED DNA METHYLATION1) is a small plant-specific protein required for RNA-directed DNA methylation (RdDM). RDM1 interacts with RNA polymerase II (Pol II), ARGONAUTE4 (AGO4), and the de novo DNA methyltransferase DOMAINS REARRANGED ...

RNA-directed DNA polymerase from particles released by normal goose cells [PDF]
Journal of Virology, 1979 Cells from a goose embryo were shown to release particle-associated RNA-directed DNA polymerase and RNase H activities that required the presence of Nonidet P-40 for detection. The particles were not infectious and did not have endogenous DNA synthesis.

Unwinding-like activity associated with avian retrovirus RNA-directed DNA polymerase [PDF]
Journal of Virology, 1978 The avian retrovirus RNA-directed DNA polymerase contains an activity that is capable of removing hydrogen bonds from duplex nucleic acid molecules. This "unwinding-like" activity appears to be specific in its action, affecting RNA.DNA and DNA.DNA duplex molecules but not RNA.RNA duplexes.

Arabidopsis C-terminal domain phosphatase-like 1 functions in miRNA accumulation and DNA methylation. [PDF]
PLoS ONE, 2013 Arabidopsis CTD-PHOSPHATASE-LIKE 1 (CPL1) is a protein phosphatase that can dephosphorylate RNA polymerase II C-terminal domain (CTD). Unlike typical CTD-phosphatases, CPL1 contains a double-stranded (ds) RNA-binding motif (dsRBM) and has been implicated

Morphological and Molecular Characterization of Pseudocercospora chionanthi-retusi Causing Leaf Spot on Chionanthus retusus in Korea [PDF]
Research in Plant Disease, 2022 Leaves of Chionanthus retusus were found to be damaged by leaf spot disease associated with a fungus in Iksan, Korea. Leaf spots were angular to irregular, vein-limited, scattered, 1–8 mm diameter, brownish-gray to dark brown when dry, with heavy ...

Polymerase IV occupancy at RNA-directed DNA methylation sites requires SHH1 [PDF]
Nature, 2013 DNA methylation is an epigenetic modification that plays critical roles in gene silencing, development, and genome integrity. In Arabidopsis, DNA methylation is established by DOMAINS REARRANGED METHYLTRANSFERASE 2 (DRM2) and targeted by 24 nt small interfering RNAs (siRNAs) through a pathway termed RNA-directed DNA methylation (RdDM)1.

Co-targeting RNA Polymerases IV and V Promotes Efficient De Novo DNA Methylation in Arabidopsis. [PDF]
, 2019 The RNA-directed DNA methylation (RdDM) pathway in plants controls gene expression via cytosine DNA methylation. The ability to manipulate RdDM would shed light on the mechanisms and applications of DNA methylation to control gene expression.

Stimulated Normal Human Lymphocytes Contain a Ribonuclease-Sensitive DNA Polymerase Distinct from Viral RNA-Directed DNA Polymerase [PDF]
Proceedings of the National Academy of Sciences, 1972 Ribonuclease-sensitive DNA synthesis is demonstrated in a cytoplasmic particulate fraction of normal human blood lymphocytes stimulated with phytohemagglutinin, but not in unstimulated lymphocytes. DNA polymerase purified from this fraction does not transcribe the heteropolymeric regions of 70S RNA from RNA tumor viruses, thus distinguishing this ...

Transcription in vitro of ø29 DNA and EcoRI fragments by Bacillus subtilis RNA polymerase [PDF]
, 1976 EcoRI fragments A, B and C produced from linear φ29 DNA, but not D or E fragments, are transcribed by purified Bacillus subtilis RNA polymerase. The transcription of fragments A and C is initiated preferentially with GTP and to a lesser extent with ATP ...
