    Summary Phenotypic suppression by the antibiotic, paromomycin, of the mitochondrial oxi1 −-V25 mutation, a mutation which arrests by premature ochre codon the synthesis of the cox 11 subunit, was studied in isolated yeast mitochondria competent in translation. This antibiotic is known to suppress the mutation in vivo (Dujardin et al. 1984) and allowed in vitro, at concentrations of 20–1100 Mg per ml. the synthesis of the cox II subunit. This strongly suggests that phenotypic suppression of mit − mutations is due to the direct action of paromomycin on mitochondrial ribosomes. The effect of paromomycin bears a resemblance to the function of the omnipotent nuclear suppressor mutation R705. The nuclear suppression was expressed in isolated mitochondria; suppressor mutation influenced the structure of the mitoribosome. Therefore, it appears that mitoribosomes are indeed the common target in the phenotypical and genetic nuclear suppression of the oxi1-V25 mutation.

    Summary Phenotypically dissimilar greenhouse isolates from a Polish collection of potato spindle tuber viroid (PSTVd) were analysed. Partially purified PSTVd genomic RNAs from severe, intermediate and mild isolates was reverse transcribed and the resulting cDNAs enzymatically amplified. Abutting-primer PCR (Ab-P PCR) technology was used to obtain, in a single step, infectious full-length PSTVd cDNA monomers and these were sequenced. The mild isolate was found to be composed of a unique molecular variant (M), closely related to previously described PSTVd mild isolates. In the intermediate isolate, three variants, i2, i3 and i4, were detected. The severe isolate was found to be a mixture containing at least four molecular variants: s23, s27, i4 and i2. Infection of test plants with plasmids carrying monomeric cDNAs corresponding to each of the cloned variants confirmed that they are infectious. In addition, variant M produced mild symptoms, variants i2, i3, i4 intermediate symptoms and variants s23 and s27 severe symptoms. Therefore, the disease symptoms produced by a mixture are determined by the severe variants, masking the presence of milder ones. All the variants detected (except i2 which is identical to previously described PSTVd-DI) represent novel PSTVd sequences with point mutations located in the V and/or P domains. In particular, variants s23 and i4 represent shorter (358 nucleotides) versions of the PSTVd genome.

    Notes:
    Summary Nucleotide sequence comparison shows that sequence variations are mostly clustered in the P (pathogenicity) and V (variable) domains of the potato spindle tuber viroid (PSTVd) molecule. Although these comparisons suggest the P domain as the primary determinant of PSTVd symptom severity, the potential contribution of the V domain has never been analysed in detail. To investigate the relationship between the structure of these domains and pathogenicity, six intraspecific chimeric PSTVd variants were constructed by exchanging P and V domains between a mild and two different severe PSTVd isolates. Infectivity studies showed that the P domain is directly responsible for the severity of symptoms induced in tomato. The four recombinants containing a P domain from a severe isolate caused severe symptoms including severe epinasty, stunting and veinal necrosis, while the two chimeras containing the mild isolate P domain induced only mild symptoms. Quantitation of viroid accumulation in plants infected with the various recombinants suggests that, with the constructions used, symptom severity did not correlate with viroid accumulation, indicating that the P domain did not influence symptom production through this simple mechanism.

    Summary.  Three potato virus Y isolates, representatives of distinct PVY groups, identified in potato fields in northern Poland were submitted to biological and molecular analysis. Phenotypically, two isolates, PVYN-Ny and PVYN-Wi, belong to the necrotic strain and the third one (PVYO-LW) to the common strain. PVYN-Wi, however, did not react with monoclonal antibodies directed against the necrotic strain isolates which recognise PVYN-Ny. To characterise the isolates, coat protein genes were sequenced and compared with sequences from databases. The necrotic PVYN-Wi isolate showed 99% amino acid homology with the common one–PVYO-LW and significantly differed from the second necrotic isolate (PVYN-Ny). Sequence based homology matrix and phylogenetic analysis lead to classification of PVYN-Ny into group I, encompassing solely necrotic strain isolates, whereas PVYN-Wi falls into a phenotypically heterogeneous group II. The sequence analysis allowed for identification of putative group I–specific epitopes. 3′NTR (non-translated region) sequences were identical for PVYN-Wi and PVYO-LW. The 5′NTR, P1 gene, coat protein gene and 3′NTR sequences of the common (PVYO-LW) and the necrotic (PVYN-Wi) isolates are 99–100% homologous. This suggests that tobacco veinal necrosis determinants are located outside the 3′ and 5′ terminal sequences of the PVY genome.
