title: The RNAs of cucumoviruses: 3'-terminal sequence analysis of two strains of tomato aspermy virus.
abstract: 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.
