Chromatin regulates expression of small RNAs to help maintain transposon methylome homeostasis in Arabidopsis
We demonstrated that thousands of transposable elements (TEs) produce exceptionally high levels of siRNAs in Arabidopsis thaliana embryos.Depending on whether they are located in euchromatic or heterochromatic regions of the genome, bipartite-classified TEs generate siRNAs throughout embryogenesis according to two distinct patterns. siRNAs are transcribed in embryos and required to direct the re-establishment of DNA methylation on TEs from which they are derived in the new generation. Overall design: Examination of  small RNAs and DNA methylation in Arabidopsis embryos and post embryonic tissues Please note that each processed data generetated from all replicates is linked to the corresponding *Rep1 sample records.
