Molecular Genetic Analysis of Non-Catalytic Pol IV and V Subunits
… exclusively for RNA directed DNA Methylation: RdDM) in addition to Pol I, II, and III. In Arabidopsis thaliana, Pol IV is required for the biogenesis of 24nt siRNAs whereas Pol V transcription is needed for cytosine methylation of the DNA sequences corresponding to these siRNAs. The ancestry of …

An Investigation into the Evolution and Function of RNA-Directed DNA Methylation and its Component Proteins
RNA-directed DNA methylation (RdDM) is a major epigenetic pathway in plants that is required to establish methylation in all contexts and maintain CHH methylation. The function of RdDM is mediated by multiple proteins that are still being characterized in land plants. Pol IV and Pol V form a major …

Dynamic regulation of DNA demethylation and RNA-directed DNA methylation in Arabidopsis
… uncovered thousands of previously unidentified RdDM (RNA-directed DNA methylation) targets by analyzing the DNA methylome of ros1/nrpd1 double mutant plants. In addition, we showed that ROS1 also antagonizes RdDM-independent DNA methylation at more than one thousand genomic loci. Our results …

Regulation and activity of the 5-methylcytosine DNA glycosylase ROS1 contributes to DNA methylation patterning across development
… ROS1 expression by interaction of ROS1 and the RdDM pathway at the ROS1 promoter. Using a previously characterized deletion in the ROS1 promoter, we investigated the consequences of ROS1 regulation across the genome in the presence of a wild-type RdDM pathway. Finally, I discuss the implications …

Small non-coding RNA-mediated epigenetic regulation of gene expression and its implications for wheat adaptation to continuous cultivation
… II entitled "RNA-directed DNA methylation (RdDM) modulates the trade-off between growth and defense and contributes to wheat adaptation to continuous cultivation" investigates the possible contribution of epigenetic modifications to wheat adaptation to long-term continuous cultivation. …

Cell Fate Specification and the Regulation of RNA-dependent DNA Methylation in the Arabidopsis Root Meristem
… of the RNA-dependent DNA methylation pathway (RdDM), including higher levels of 24-nt silencing RNAs (siRNAs). In summary, our studies demonstrate the versatility of high-throughput sequencing as a method for identifying single mutations or to perform complex comparative genomic analyses.</p>
