Abstract
One of the most efficient mechanisms by which plants protect themselves from viruses is the specific RNA-dependent silencing pathway termed post-transcriptional gene silencing (PTGS). Inhibition of Tobacco mosaicvirus in tobacco was demonstrated through transient expression of virus-derived short hairpin RNA encoding the methyltransferase domain of TMV replicase corresponding to the nucleotides 630 to 1,510 introduced through agro-infiltration into the leaves of tobacco plants. RT-PCR revealed that TMV infection was absent in hpRNA agro-infiltrated leaves while control leaves showed amplification of TMV. Protein analysis further confirmed the absence of TMV coat protein in hpRNA-containing leaves while it was prominent in the control leaves. Our data demonstrate that expression of hpRNA is an effective and predictable new approach to engineering resistance to TMV.
