A strain of Cucumber mosaic virus (CMV-D8) systemically infects Japanese radish (Raphanus sativus), but the Y strain of CMV (CMV-Y) only infects the inoculated leaves. Both of these strains cause severe systemic mosaic on the plants after dual infection with Turnip mosaic virus (TuMV). Synergistic interactions on long-distance transport of CMV-Y and CMV-D8 with TuMV were analyzed using an immunobinding assay. Direct tissue blots probed with either anti-CMV-Y or anti-TuMV antiserum clearly showed that CMV-Y efficiently spread and accumulated in the tissues of noninoculated upper leaves and roots when co-inoculated with TuMV, and that long-distance movement of CMV-D8 was enhanced by the presence of TuMV.
