【 摘 要 】

Comoviruses have a bipartite RNA genome. It is suggested that a small protein, VPg, is covalently linked to both RNAs. We have found that both radish mosaic virus RNAs are linked to identical VPg molecules via a phosphodiester bond between their 5′-terminal nucleotides and a serine residue of VPg.
