A movement protein Potato virus X (PVX) chimera virus (PVX.GFP(CH3)) bearing the grapevine virus Grapevine rupestris stem pitting-associated virus (GRSPaV) triple gene block proteins (TGB) (denoted P1, P2 and P3) instead of the PVX TGB was delivered into N. benthamiana and other related species by agro-inoculation. This movement protein PVX chimera virus was found to be unable to support the local and systemic movement of PVX in cis. Local and systemic movement of this PVX chimera virus was restored in trans by the dianthovirus Red clover necrotic mosaic virus (RCNMV) movement protein and by a PVX TGB rescue virus that replaced the GRSPaV TGB with the PVX TGB (PVX.GFP(Rescue)). However, a PVX TGB hybrid chimera virus (PVX.GFP(HY2)) containing PVX P1 and the GRSPaV TGB had limited cell-to-cell, but not systemic, movement.
