Comparison of virus particles and intercellular inclusions associated with vein mosaic, feather mottle, and russet crack diseases of sweet potato


, : Comparison of virus particles and intercellular inclusions associated with vein mosaic, feather mottle, and russet crack diseases of sweet potato. Phytopathologische Zeitschrift 79(2): 169-178

All 3 viruses produced morphologically identical pinwheel, tubular and laminate inclusions in the cytoplasm of infected leaves. The relative preponderance of different types of inclusion varied with age of infection. Virus particles were also observed in the cytoplasm and in plasmodesmata. Particle lengths were: vein mosaic 767nm, feathery mottle 844 and russet crack 876.

A new filamentous virus (designated VC) was isolated from sweet potato plants that seemed to be tolerant to russet crack. It infected Ipomoea spp., Chenopodium quinoa and C. amaranticolor. Ipomoea nil infected with the virus developed typical vein...
