Defective Long-distance Transport of Cucumber mosaic virus in Radish Is Efficiently Complemented by Turnip mosaic virus

  • Minoru TAKESHITA

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.

Key words : Cucumber mosaic virus, Turnip mosaic virus, Raphanus sativus, synergistic interaction, complementation, co-infection.
