“…Among the plethora of diseases affecting potato plants that viral etiology is the most common and causes significant damage to seed and tuber production. According to numerous sources, there are 40–50 viruses that infect potato plants all over the world (Bashir et al, 2021; Kreuze et al, 2020; Loebenstein et al, 2001; Valkonen, 2007; Wang et al, 2011), of which the following are considered the main significant potato viruses: Potato leafroll virus, Luteovirus (PLRV), Potato virus A, Potyvirus (PVA), Potato virus Y, Potyvirus (PVY), Potato virus X, Potexvirus (PVX), Potato virus S, Carlavirus (PVS), and Potato virus M, Carlavirus (PVM) (Bai et al, 2007; Rogozina et al, 2019; Valkonen, 2015; Wang et al, 2011; Zhang et al, 2010).…”

“…Viral infection of potato plants affects both the yield and quality of potatoes (Kotzampigikis et al, 2008). Contemporary research suggests that the loss of yield associated with viral infection of potato plants varies from 10 to 80% (Awasthi & Verma, 2017; Bashir et al, 2021; Hao et al, 2007; Huang et al, 2009; Kumar et al, 2020; Kumar et al, 2019; Wang et al, 2011; Wang et al, 2005; Whitworth et al, 2006). Most damaging effects are observed in the plants infected by PLRV and PVY (Kotzampigikis et al, 2008; Weidemann, 1988).…”

“…Viruses, being obligate parasites and affecting the metabolism of plants, cause a violation of physiological processes, resulting in a decrease not only in the productivity of plants but also affecting the biochemical composition of tubers. As a result, plants grown from previously infected seed tubers (secondary infection) usually produce tubers unsuitable for sale (Bashir et al, 2021).…”

Potato virus Y (PVY), Potato virus S (PVS), and Potato virus M (PVM) infection of potato plants leads to decreased dry matter and starch content in tubers. Starch samples from potato tubers infected with PVY, PVS, and PVM had higher amylose content. Granules of starch isolated from potato tubers infected by PVS exhibit larger granules than starch granules isolated from tubers of healthy plants. In contrast, in the case of PVM and PVY infection, starch granules were significantly smaller in diameter. A decrease in the degree of crystallinity has been observed in all samples of starches obtained from the tubers of infected plants compared to starch isolated from tubers of healthy plants. A slight decrease in gelatinization temperature was noted for starch samples isolated from tubers infected by PVY and PVM, and a slight increase in gelatinization temperature for starch samples isolated from tubers infected by PVS compared to starch isolated from tubers of healthy plants. In all samples of starch obtained from tubers of infected plants, an increase in the value of gelatinization enthalpy was observed. Thus, it can be concluded that damage to potato plants by PVM and PVY leads to a significant decrease in the quality of starch in tubers. At the same time, infection by PVS had practically no considerable effect.

Potatoes (Solanum tuberosum L.) are the fourth most economically important crop in the world. They have a short period of vegetation and are an excellent source of carbohydrates, amino acids, vitamins, organic acids, minerals and phenolics as antioxidant substances. Potato can be a major dietary source of various bioactive compounds. In this study, we applied gas chromatography coupled with mass spectrometry (GC-MS) metabolite profiling to classify eight Bulgarian potato cultivars bred in the Maritsa Vegetable Crops Research Institute (VCRI), Plovdiv, according to their metabolite contents. Altogether, we determine their flavonoids/phenolics to evaluate their nutritive quality for the breeding program with the target of determining strong health-promoting compounds. The “Kalina” cultivar is highlighted as the best one with the highest number of metabolites, containing 14 out of the 26 evaluated; it was selected as the highest-quality cultivar, compared with the other seven cultivars studied. According to the grouping of the cultivars in principal component analysis PCA, their positive distribution is explained mainly by them having the highest contents of aminobutyric and isocitric acids, methionine and alanine and lower levels of fumaric acid, pyroglutamic acid and glycine, in contrast to the cultivars distributed negatively, which had high contents of carbohydrates and relatively low contents of most of the amino acids. The highest number of amino acids was found in the cultivar “Kalina”, followed by “Perun” and “Bor”. The highest number of carbohydrates was found in “Pavelsko” and “Iverce”, while the prominent accumulation of organic acids was found in “Kalina”, “Bor” and “Rozhen”. The highest number of flavonoids in the flesh of the tubers was found in the cultivars “Nadezhda” and “Pavelsko”, followed by “Bor”. The highest ratio of flavonoids/phenolics in the flesh was found in “Pavelsko” and in “Nadezhda”, followed by “Iverce”.

Inbred‐hybrid breeding of diploid potatoes necessitates breeding lines that are self‐compatible. One way of incorporating self‐compatibility into incompatible cultivated potato (Solanum tuberosum) germplasm is to introduce the S‐locus inhibitor gene (Sli), which functions as a dominant inhibitor of gametophytic self‐incompatibility. To learn more about Sli diversity and function in wild species relatives of cultivated potato, we obtained Sli gene sequences that extended from the 5′UTR to the 3′UTR from 133 individuals from 22 wild species relatives of potato and eight diverse cultivated potato clones. DNA sequence alignment and phylogenetic trees based on genomic and protein sequences show that there are two highly conserved groups of Sli sequences. DNA sequences in one group contain the 533 bp insertion upstream of the start codon identified previously in self‐compatible potato. The second group lacks the insertion. Three diploid and four polyploid individuals of wild species collected from geographically disjointed localities contained Sli with the 533 bp insertion. For most of the wild species clones examined, however, Sli did not have the insertion. Phylogenetic analysis indicated that Sli sequences with the insertion, in wild species and in cultivated clones, trace back to a single origin. Some diploid wild potatoes that have Sli with the insertion were self‐incompatible and some wild potatoes that lack the insertion were self‐compatible. Although there is evidence of positive selection for some codon positions in Sli, there is no evidence of diversifying selection at the gene level. In silico analysis of Sli protein structure did not support the hypothesis that amino acid changes from wild‐type (no insertion) to insertion‐type account for changes in protein function. Our study demonstrated that genetic factors besides the Sli gene must be important for conditioning a switch in the mating system from self‐incompatible to self‐compatible in wild potatoes.
