Plaque assay showing an increase in FHV titers in inoculated leaves of MP-transgenic N. benthamiana plants. Leaves harvested 12 days after inoculation were homogenized and assayed for infectious FHV as described in the text. Five microliters of 1-ml homogenates derived from 100 mg of leaf tissues were used in each assay after appropriate dilutions (100-fold for nontransgenic and 1,000-fold for transgenic). Plates: 1, buffer-inoculated transgenic; 2, FHV RNA-inoculated nontransgenic; 3, FHV RNA-inoculated TMV-MP transgenic; 4, FHV RNA-inoculated RCNMV-MP transgenic leaf homogenates.
