Nodamura virus is a small ribovirus containing two RNA molecules. Both RNAs were found to be active messengers for protein synthesis in cell-free extracts prepared from wheat embryo or HeLa cells. RNA 2 directed synthesis of a 43,000-dalton product, p43, whose tryptic fingerprint was similar to that of the major viral coat protein, vp40 (molecular weight, 40,000). Though p43 appears to be a precursor of vp40, processing did not occur in the cell-free extracts. RNA 1 directed synthesis of a 105,000-dalton protein, p105. Its tryptic fingerprint revealed no evidence of coat protein sequences. Hence, the two RNAs represent genes with few, if any, redundant coding sequences.
