Patent ID: 8597942

Claim:
A system for expressing a polynucleotide of interest in a plant cell or whole plant, comprising: (i) a carrier vector that includes a functional coat protein encoding component from a first plant virus; and a producer vector that includes the polynucleotide of interest, and further includes at least one component from a second plant virus, but lacks a functional coat protein encoding component; or (ii) a carrier vector that includes a functional replicase encoding component from a first plant virus; and a producer vector that includes the polynucleotide of interest, and further includes at least one component from a second plant virus, but lacks a functional replicase encoding component; or (iii) a carrier vector that includes a functional movement protein encoding component from a first plant virus; and a producer vector that includes the polynucleotide of interest, and further includes at least one component from a second plant virus, but lacks a functional movement protein encoding component; wherein the polynucleotide of interest encodes an active RNA species.
