The present invention discloses methods for interfering with expression of t he genes in plant cells by using replicating recombinant viral vectors. A host plant is infected at one or more locations with a recombinant viral vector. The vector is both an initiator and a target of the RNA-triggered gene silencing in plant cells. The vector upon infection is capable of directing self-replication and producing a transcription product of a nucleic acid segment. The transcription product interferes with the expression of a specific gene in plant cells.
