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 os (+)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 os the circular and linear (+)PSTV monomers accumulating in the cell nucleus.
