Popis: Expression vectors based on the bipartite Cowpea Mosaic Virus (CPMV) have been investigated for use in molecular farming in plants. Agroinfiltration into Nicotiana benthamiana of two full-length RNA-2 constructs containing different marker genes in the presence of RNA-1 showed that two foreign proteins can be efficiently expressed within the same cell in inoculated tissue. However, segregation of the RNA-2 molecules was observed upon systemic spread of the recombinant viruses. Thus efficient assembly of heteromeric proteins is likely to occur only in inoculated tissue. Therefore vectors based on full-length RNA-2 molecules do not have an advantage over vectors based on deleted versions of RNA-2 that are restricted to infiltrated tissue.
