Abstract excerpt
It has been known for more than a decade that increasing the gene copy number does not necessarily lead to increased gene activity. Plants have developed efficient mechanisms such as post-transcriptional gene silencing (PTGS) to regulate abnormal gene expression in a sequence-specific fashion. PTGS of (trans)genes can be inhibited by non-homologous viruses, and PTGS-impaired mutants can be hypersensitive to such...
