TranscriptomicsIncorporation of transposable element small RNAs into the Arabidopsis AGO1 protein
Background: Transposable element 24 nucleotide small RNAs are not efficiently incorporated into the AGO1 protein, which is involved in endogenous RNAi and gene regulation through the microRNA and tasiRNA pathways. Results: The AGO1 protein incorporates large quantities of transposable element siRNA...

TranscriptomicsGene expression in Arabidopsis ddm1 mutants with high levels of Transposable Element activity
Background: Transposable elements are known to influence the regulation of some genes. We aimed to determine which genes show altered gene expression when transposable elements are epigenetically activated. Results: We find over 2000 genes with altered steady-state expression levels in ddm1 mutants....

TranscriptomicsSmall RNA accumulation in Transposable Element-silent and Transposable Element-active epigenomes
Background: The small RNAs that Transposable Elements generate are vastly different when they are transcriptionally silenced compared to when they are transcriptionally activated. We performed the deep sequencing of small RNAs in a number of small RNA biogenesis mutants in both Transposable Element-...

TranscriptomicsThe exon junction complex controls transposable element activity by ensuring faithful splicing of the piwi transcript
The exon junction complex (EJC) is a highly conserved ribonucleoprotein complex which binds RNAs during splicing and remains associated with them following export to the cytoplasm. While the role of this complex in mRNA localization, translation and degradation has been well characterized, its mecha...

TranscriptomicsExtensive demethylation of repetitive elements during seed development underlies gene imprinting
DNA methylation is an epigenetic mark associated with transposable element silencing and gene imprinting in flowering plants and mammals. In plants, imprinting occurs in the endosperm, which nourishes the embryo during seed development. We have profiled Arabidopsis DNA methylation genome-wide in the...

TranscriptomicspiRNA-mediated transgenerational inheritance of an acquired trait
The maintenance of genome integrity is an essential trait to the successful transmission of genetic information. In animal germ cells, piRNAs guide PIWI proteins to silence transposable elements (TEs) in order to maintain genome integrity. In insects, most of TE silencing in the germline is achieved...

Investigation of the effect of the knockdown of AT-hook motif DNA binding nuclear matrix protein TRANSPOSABLE ELEMENT KILLER (TEK) in the Arabidopsis Landsberg erecta (Ler) background Transposable elements (TEs) are silenced by epigenetic mechanisms of DNA and histone methylation. The repressive his...
