Tomato black ring virus
Opis:
Several different isolates of Tomato black ring virus (TBRV) have been collected in Poland from cucumber, tomato, potato and black locust plants. Biological tests showed some differences in the range of infected plants and the type of symptoms, which was the basis for selection of seven the most biologically different TBRV isolates. According to the sequence of TBRV-MJ, several primer pairs were designed and almost the entire sequence of both genomic RNAs was amplified. The RT-PCR products derived from all tested TBRV isolates were digested by restriction enzymes. On the basis of the restriction patterns, the variable and the conserved regions of the TBRV genome were defined and the relationships between the Polish TBRV isolates established.

Opis:
Peanut stunt virus (PSV) is a common legume pathogen present worldwide. It is also infectious for many other plants including peanut and some vegetables. Viruses of this species are classified at present into three subgroups based on their serology and nucleotide homology. Some of them may also carry an additional subviral element - satellite RNA. Analysis of the full genome sequence of a Polish strain - PSV-P - associated with satRNA was performed and showed that it may be classified as a derivative of the subgroup I sharing 83.9-87.9% nucleotide homology with other members of this subgroup. A comparative study of sequenced PSV strains indicates that PSV-P shows the highest identity level with PSV-ER or PSV-J depending on the region used for analysis. Phylogenetic analyses, on the other hand, have revealed that PSV-P is related to representatives of the subgroup I to the same degree, with the exception of the coat protein coding sequence where PSV-P is clustered together with PSV-ER.

Opis:
The complete nucleotide sequence of a Polish isolate of Beet soil-borne virus was determined for the first time. The genome organization was identical with those previously established for isolates from Germany and China. A comparison of the Polish isolate with others deposited in GenBank reveled high level of nucleotide identity, about 98-100%, throughout the genome analyzed. The ratio between non-synonymous and synonymous substitutions was rather low suggesting a negative selective pressure. The non-synonymous mutations were particulary frequent in triple gene block.

Opis:
Genetic recombination plays an important role in the evolution of virus genomes. In this study we analyzed publicly available genomic sequences of Pepino mosaic virus (PepMV) for recombination events using several bioinformatics tools. The genome-wide analyses not only confirm the presence of previously found recombination events in PepMV but also provide the first evidence for double recombinant origin of the US2 isolate.
