FIG. 4.

Expression and packaging profiles for BMV and FHV agrotransformants in N. benthamiana. Northern blotting analyses of total (top panels A to D) and virion (bottom panels A to D) RNA recovered from N. benthamiana leaves infiltrated with the indicated sets of inocula. Multiple blots were produced and hybridized with the indicated riboprobes. Hybridization conditions are as described in the legend to Fig. 1. The positions of FHV and BMV RNA are shown. The method used to purify virions is shown below each panel.
