Satellite-like Particle of Tobacco Ringspot Virus That Resembles Tobacco Ringspot Virus

Abstract

A satellite-like nucleoprotein serologically indistinguishable from multicomponent tobacco ringspot virus, also resembles it in size, shape, and electrophoretic mobility. Although the protein shell of the nucleoprotein is similar to, if not identical to that of tobacco ringspot virus, each ahell of the nucleoprotein conntains many small strands of nucleic acid, which replicate only in mixed infections with the virus.
