RECOMBINANT ALSV FOR PREVENTING PATHOGENIC VIRAL INFECTION OF PLANT

摘要

The invention provides a recombinant apple latent spherical virus (ALSV). The recombinant ALSV contains a partial fragment of a genomic RNA or cDNA from one or more plant pathogenic viruses, and manifests an interference effect against these plant pathogenic viruses. The invention thus provides a novel means of defending against infection of a plant pathogenic virus, without the risk of becoming virulence in the course of proliferation.
