Abstract
This invention provides a method to silence an endogenous target gene expression in plants by applying a specific dsRNA onto the exterior surface of a plant. Application, such as by spraying or brushing a plant with dsRNA is done without wounding the plant tissue and cells such as by mechanical-type wounding, particle bombardment or mechanical infection with viral vectors. The present invention enables the regulation of gene expression in plants. In some embodiments of the invention, the dsRNA is directed to an essential gene of a plant pathogen or pest, whereby the pathogen and/or pest damage is controlled, resulting in desired agronomic performance.
