Hairpin RNA induces secondary small interfering RNA synthesis and silencing in trans in fission yeast


ABSTRACT: We provide evidence of the generation of Rdp1-mediated secondary siRNAs in vivo in fission yeast. Secondly, we show that the presence of Ago1-associated siRNAs does not guarantee robust silencing. We obtained sequences from gel purified small RNAs of wt and rdp1delta fission yeast cells and FLAG-ago1 associated small RNAs.

RNA interference (RNAi) is widespread in eukaryotes and regulates gene expression transcriptionally or post-transcriptionally. In fission yeast, RNAi is tightly coupled to template transcription and chromatin modifications that establish heterochromatin in cis. Exogenous double-stranded RNA (dsRNA) triggers seem to induce heterochromatin formation in trans only when certain silencing proteins are overexpressed. Here, we show that green fluorescent protein (GFP) hairpin dsRNA allows production of  ...[more]
