  • Title: The nature of multimeric forms of cymbidium ringspot tombusvirus satellite RNA.
    Author: Dalmay T, Rubino L.
    Journal: Arch Virol; 1994; 138(1-2):161-7. PubMed ID: 7526827.
    Abstract:
    The multimeric forms of cymbidium ringspot tombusvirus (CyRSV) satellite (sat) RNA were analysed. Attempts to amplify the putative junction region of oligomers using the polymerase chain reaction (PCR) failed, indicating the absence of such structures. SatRNA-related species having the size double than the unit length were shown to be double-stranded monomers and not single-stranded dimers. Similarly, satRNA species of a size four times the unit length were shown to be constituted by aggregates of double-stranded monomers. The absence of single-stranded CyRSV satRNA oligomers indicates that the formation of multimers is not a step in the replication of this RNA molecule.
