Abstract: Methods and compositions comprising an expression construct and a suppressor of posttranscriptional gene silencing construct are described. The expression construct and suppressor construct may comprise a viral amplicon. The expression construct may comprise fusing the target gene to the 3? and/or 5? end of a gene encoding a transit peptide sequence or a signaling peptide sequences. The transit or signal peptide sequence directs the target gene product to a subcellular location. Methods comprise the production of several heterologous proteins in a single plant. The invention comprises methods for plant production and protein harvest that will yield useful amounts of the desired protein(s) in as little as one to two weeks after the initiation of the production cycle. Methods for the inoculation of recipient plants by spraying with recombinant Agrobacterium suspensions containing the constructs of interest are taught.
