Potato (Solanum tuberosum L.) is the fourth most important food crop in the world. It is the most economically valuable and well-known member of the plant family Solanaceae. Potato is the host of many pathogens, including fungi, bacteria, Phytoplasmas, viruses, viroids and nematodes, which cause reductions in the quantity and quality of yield. Apart from the late blight fungus [Phytophthora infestans (Mont.) de Bary] viruses are the most important pathogens, with over 40 viruses and virus-like pathogens infecting cultivated potatoes in the field, among which Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus X (PVX), Potato virus A (PVA), Potato virus S (PVS) and Potato virus M (PVM) are some of the most important viruses in the world. In this review, their characteristics and types of resistance to them will be discussed.

Objective. Monitoring observations over the phytovirological condition of potato planting in different regions of Ukraine, taking into account potato degeneration zones. Methods. Laboratory (virological, immunological, electronic microscopy), field, statistical. Results. The map and diagrams show the results of monitoring studies conducted in 2016–2020, during which 435 varieties of potatoes of Ukrainian and foreign selection were tested. In the zone of the lowest degeneration or the zone with a relatively low degree of infectious load, 100 % spread of pathogenic complexes involving potato virus Y in the Region of Zakarpattia, potato viruses M and Y in the Region of Chernivtsi, ranging from 89 % to 100 %. In the zone of strong degeneration of the culture or the zone with a high degree of infectious load, spread of pathogens of potato viral diseases is from 94 % to 100 %, and the vast majority of viruses belongs to pathogens of severe viral diseases. In the zones of mild and moderate degeneration, which belong to the zones with relatively low degree and with moderate degree of infectious load according to another diagram, potato virus M in monoinfection from 17 % to 50 %, in the pathogenic complex with potato virus S from 8 % to 36 %, with potato virus Y from 6 % to 32 % was detected. In the Region of Kyiv, the spread of potato virus Y+S complex reaches 65 %. In all areas, there is an extremely high level of infection of the culture with potato virus M, which is the cause of severe viral diseases of potatoes. Conclusion. The results of phytovirological monitoring show that the boundaries between potato degeneration zones are smoothed down. Climatic changes, active resettlement of virus vectors, intensification of trade relations with the constant import of foreign potato seed material result in the significant spread of pathogens of potato viral diseases.

Over the past 10 years, Tomato yellow vein streak virus (ToYVSV) has been a major begomovirus in the main solanaceous crop region of Campinas, São Paulo, which includes counties of Sumaré, Monte Mor, Elias Fausto, and Indaiatuba. The top leaves of potato plants (Solanum tuberosum) having deforming mosaic symptoms (dms), which includes a yellow mosaic or mottling on distorted and deformed leaflets, were associated with this geminivirus (4). Recently, a table potato crop (cv. Agata) from Sumaré, with a record of a few or no white flies (Bemisia tabaci), during the winter season of June to September 2006 had 5 to 7% dms, suggestive of seed potato tuber borne virus infection. Double-antibody sandwich (DAS)-ELISA for Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus X (PVX), and Potato virus S (PVS) (SASA kits and protocols, Edinburgh, Scotland) gave negative results for four field collected potato plants showing dms. Bioassays (mechanical transmission from potato leaf extracts in phosphate buffered saline, 1:5 w/v) with test plants of Nicotiana tabaccum cvs. Turkish and TNN, Gomphrena globosa, Chenopodium quinoa, Datura metel, Solanum tuberosum, and a Physalis sp. were all negative. Inoculated D. stramonium developed symptoms resembling ToYVSV infection including vein clearing and mild mottling on new leaves 2 to 3 weeks postinoculation. Using primers PAC1v1978/PAV1c715 for begomovirus detection (3), the predicted PCR amplified fragment of 1,320 bp was obtained from leaf DNA extracted from all four of the dms field potato plants, as well as the inoculated and symptomatic D. stramoniium test plants. Sequence analysis indicated 100% nt identity among the 1.3-kb PCR fragments obtained from potato and D. stramonium infected plants. Sequences of 96 cloned amplicons (pGEM-T Easy Kit; Promega, Madison, WI) from symptomatic plants in the Sumaré potato field were 98 to 99% identical to Tomato severe rugose virus (ToSRV). BLAST analysis of a consensus sequence (Sequencher 3.1; Gene Codes Corporation, Ann Arbor, MI) revealed more than 95 and 99% identity with ToSRV isolates from Uberlandia (Accession No. AY029750) and Goias (Accession No. DQ207749), respectively. The DNA-based phylogenetic dendrogram confirmed the highest similarity with ToSRV and the lowest similarity with ToYVSV (72%), which was located in another cluster. These results indicate that ToSRV was the causal agent producing dms in potato plants from Sumaré. Therefore, similarly to ToYVSV (4), potato dms can be caused by ToSRV. Preliminary tests revealed that ToSRV was transmitted via seed tubers. Thus, it is of concern for seed potato certification in Brazil, especially in the major seed-potato-producing state of Santa Catarina where an outbreak of ToSRV was recently reported in tomato crops (1). Although ToSRV has been identified in other solanaceous crops in Brazil, especially tomato (Lycopersicon esculentum) and sweet pepper (Capsicum annum) (2), to our knowledge, this is the first report of ToSRV in potato in Brazil.

Potato Crops

Three consecutive potato crops are grown annually in Pakistan and Khyber Pakhtunkhawa (KPK) province is the main source for seed tubers. During the year 2010, 240 symptomatic and viral susceptible potato leave samples were collected from Swat, Dir, Abbottabad and Mansehra and serologically confirmed through Double Antibody Sandwich (DAS) Enzyme Linked Immunosorbant Assay (ELISA) against Potato virus X (PVX), Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus M (PVM), Potato virus S (PVS) and Potato virus A (PVA). The presence or absence of viruses was confirmed by observing the yellow and white color in ELISA plates respectively. According to ELISA results, overall percentage incidence of viral diseases was found highest in Swat (65%) followed by Mansehra (61%), Dir (53%) and Abbottabad (43.33%) while PVY and PVS were dominant in Swat (26.66%), Dir (20%), Mansehra (15%) and Abbottabad (21.66%) respectively. PVX was not detected in Abbottabad while Swat samples seemed to be free from PVM and PVA.

Weeds as reservoirs for destructive plant pathogens have a significant impact on the viral epidemiology, ecology and, as a result, on local economy, and are therefore being investigated in many parts of the world. Thus, the aim of this study was to investigate virus occurrence in red dead-nettle plants (Lamium purpureum L.) widespread in urban and field conditions throughout the in the Kyiv region of Ukraine. Methods. Field crop observations, visual diagnosis, biological testing of the virus, immunoassay (ELISA), polymerase chain reaction with reverse transcription (RT-PCR), sanger sequencing of partial genome sequences of PVX, PVY, PVS, PVM. Results. The results obtained in the study indicate that Lamium plants could be alternative weed hosts of number important viral diseases including potatoes and other vegetables. Serological and molecular test results evidence plants were infected by Potato virus X, Potato virus Y, Potato virus M, Potato virus S and therefore Lamium L. species can serve as a potential source of inoculum for wide range of vegetables and ornamentals. This study is the first report of Lamium plants being naturally infected with Potato virus M and Potato virus S in central Europe. Conclusions. These plants are alternative host of mixed infection with viruses belonging to different families: Alphaflexiviridae, Betaflexiviridae and Potyviridae.
