  • Title: Oligomeric forms of potato spindle tuber viroid (PSTV) and of its complementary RNA are present in nuclei isolated from viroid-infected potato cells.
    Author: Spiesmacher E, Mühlbach HP, Schnölzer M, Haas B, Sänger HL.
    Journal: Biosci Rep; 1983 Aug; 3(8):767-74. PubMed ID: 6626709.
    Abstract:
    Different oligomeric forms of PSTV are detected in nuclei isolated from PSTV-infected potato cells by means of molecular hybridization, using as probes synthetic oligodeoxyribonucleotides with sequence specificity for (+)PSTV and for (-)PSTV. In addition to several species of longer-than-unit-length (-)PSTV molecules, two oligomeric forms of (+)PSTV are detected, which correspond in size to RNA strands of approximately two and three times viroid unit-length. They must be considered as the precursors of the circular and linear (+)PSTV monomers accumulating in the cell nucleus.
