Core Proteins

ABSTRACT Rice dwarf virus (RDV) is a double-shelled particle that contains a major capsid protein (P8), a major core protein (P3), several minor core proteins, and viral genomic double-stranded RNA. Coexpression of P8 and P3 in transgenic rice plants resulted in formation of double-shelled, virus-like particles (VLPs) similar to the authentic RDV particles. The VLPs were not detected in transgenic rice plant cells expressing P8 alone. This in vivo result suggests that P8 interacted with P3 and that these two proteins provide the structural integrity required for the formation of VLPs in rice cells independently of other structural proteins, nonstructural proteins, or viral genomic double-stranded RNAs.

Race 2

Virus-like particles were observed in five North Dakota isolates of Plasmopara halstedii race 2, the causal agent of sunflower downy mildew. Virus-like particles were observed in fungal mycelium within sunflower seedlings showing typical symptoms of systemic infection as well as from seedlings displaying "twisted leaf syndrome." Virus-like particles were never observed in sunflower cells. The particles were isometric in shape and measured 23–26 nm in thin sections and 32 nm after phosphotungstic acid staining. Virus-like particles occurred dispersed throughout the cytoplasm and in membrane-bound organelles. Both crystalline and noncrystalline arrays were common. The particles were observed in haustoria, intercellular hypha, sporangiophores, zoosporangia, and oospores. Four species of double-stranded RNA were detected in sunflower tissue infected with P. halstedii; none were detected in healthy sunflower tissue. This is only the second report of an isometric, virus-like particle occurring in a member of the Peronosporales. Key words: mycovirus, downy mildew, Helianthus annuus.
