miRNAs trigger widespread epigenetically-activated siRNAs from transposons in Arabidopsis

In plants, post-transcriptional gene silencing (PTGS) is mediated by DICER-LIKE1 (DCL1)-dependent miRNAs, that also trigger 21-nt secondary siRNA via RNA DEPENDENT RNA POLYMERASE6 (RDR6), DCL4, and ARGONAUTE1 (AGO1)(1–3), while transcriptional gene silencing (TGS) of transposons is mediated by 24-nt...
