The RNAs of cucumoviruses: 3'-terminal sequence analysis of two strains of tomato aspermy virus.
The sequences of 189 residues from the 3' terminus of three RNAs of one strain and two RNAs of another strain of tomato aspermy virus have been determined; there was almost complete sequence homology between the RNAs. A base-paired transfer RNA-like structure is proposed for tomato aspermy virus RNAs which is similar in many aspects to the structure proposed for the 3'-terminal 172 residues of RNA 4 of the Q-strain of cucumber mosaic virus (R. H. Symons, Nucleic Acids Res.7, 825-837, 1979). These 172 residues of cucumber mosaic virus RNA 4 can be aligned to show 73% sequence homology with the 3'-terminal 189 residues of the tomato aspermy virus RNAs.
