TranscriptomicsDeep sequencing of small RNAs in the trasngenic wild type plant and the IWR1-type transcription factor mutant, dms4
Full title: Deep sequencing of small RNAs in the trasngenic wild type plant (contains trigger and silencer transgenes) and the IWR1-type transcription factor mutant, dms4 RNA-directed DNA methylation (RdDM) in plants requires two RNA polymerase II (PolII)-related RNA polymerases named PolIV and Pol...

TranscriptomicsAtypical DNA methylation of genes encoding cysteine-rich peptides in Arabidopsis thaliana
In plants, transposons and non-protein-coding repeats are epigenetically silenced by CG and non-CG methylation. This pattern of methylation is mediated in part by small RNAs and two specialized RNA polymerases, Pol IV and Pol V, in a process called RNA-directed DNA methylation. By contrast, many pr...

TranscriptomicsAGO6 functions in RNA-mediated transcriptional gene silencing in shoot and root meristems in Arabidopsis thaliana
RNA-directed DNA methylation (RdDM) is a small interfering RNA (siRNA)-mediated epigenetic modification that contributes to transposon silencing in plants. RdDM requires a complex transcriptional machinery that includes specialized RNA polymerases, named Pol IV and Pol V, as well as chromatin remode...

TranscriptomicsTrim33 binds and silences a class of young endogenous retroviruses in the mouse testis
Transposable elements (TEs) have been active in the mammalian genome for hundreds of millions of years and each TE has had a distinct period of transpositional activity, followed by inactivation. Mice carrying reporter transgenes can be used to model transcriptional silencing at TEs. A mutagenesis s...
