title: Purification and characterization of a virus from the aphid Rhopalosiphum padi.
abstract: A 27-nm icosahedral virus was purified from the oat bird cherry aphid, Rhopalosiphum padi (L.). The virus had an s(20,w) of 162 +/- 2 S, and bouyant densities of 1.37 in CsCl and 1.35 in Cs2SO4. It contained one ssRNA of 31 +/- 2 S and three major proteins. The relationship of the R. padi virus to other small RNA invertebrate viruses is unclear.
