Abstract excerpt
Viroid infection is associated with the production of short interfering RNAs (siRNAs), a hallmark of post-transcriptional gene silencing (PTGS). However, viroid RNAs autonomously replicating in the nucleus have not been shown to trigger the degradation of homologous RNA in the cytoplasm. To investigate the potential of viroids for the induction of gene silencing, non-infectious fragments of potato spindle tuber...
