Improving initial infectivity of the Turnip mosaic virus (TuMV) infectious clone by an mini binary vector via agro-infiltration.

Background: The in vivo infectious clone of Turnip mosaic virus (TuMV), p35S-TuMV, was used on plant pathology research for many years. To activate p35S-TuMV, the plasmid was mechanically introduced to the local lesion host Chenopodium quinoa. However, low infectivity occurred when the TuMV from C.
