| 摘要 |
The present invention provides recombinant DNA constructs for inactivation of viral or endogenous genes in a cell, wherein the construct comprises viral sequence sufficient to activate RNA silencing. In another aspect, the invention provides methods for identifying RNA silencing suppressors by sequence analysis and functional tests. In yet another aspect, the invention provides a method for identifying inhibitors of RNA silencing suppressors. In still other aspects, the invention comprises methods for identifying genes in the antiviral RNA silencing pathway, enhancers of the antiviral pathway, and methods of treating or preventing viral infections using enhancers of the pathway.
