“…Cultivated potatoes grown in South America were found to contain homologs of genes providing reliable protection against late blight, which had been found in the South American wild species S. venturii and the Mexican species S. bulbocastanum and S. stoloniferum, as well as homologs of race-specific late blight resistance genes from the North American species S. demissum. Previously, molecular genetic screening of accessions from the VIR potato collection revealed the presence of SCAR markers of the Rpi genes from wild potato species of the North and South American series, and in samples of PCPS (Muratova et al, 2020;Gurina et al, 2022;Rogozina et al, 2023). The similarity of wild and cultivated potatoes in genes of resistance to the highly specialized pathogen Phytophthora infestans (Mont.)…”

Pathogen recognition receptors encoded by R genes play a key role in plant protection. Nowadays, R genes are a basis for breeding many crops, including potato. Many potato R genes have been discovered and found suitable for breeding thanks to the studies of a wide variety of wild potato species. The use of primitive cultivated potato species (PCPS) as representatives of the primary gene pool can also be promising in this respect. PCPS are the closest to the early domesticated forms of potato; therefore, their investigation could help understand the evolution of R genes. The present study was aimed at identifying and analyzing R genes in PCPS listed in the open database of NCBI and Solomics DB. In total, the study involved 27 accessions belonging to three species: Solanum phureja Juz. & Bukasov, S. stenotomum Juz. & Bukasov and S. goniocalyx Juz. & Bukasov Materials for the analysis were the sequencing data for the said three species from the PRJNA394943 and PRJCA006011 projects. An in silico search was carried out for sequences homologous to 26 R genes identified in potato species differing in phylogenetic distance from PCPS, namely nightshade (S. americanum), North- (S. bulbocastanum, S. demissum) and South-American (S. venturii, S. berthaultii) wild potato species, as well as the cultivated potato species S. tuberosum and S. andigenum. Homologs of all investigated protein-coding sequences were discovered in PCPS with a relatively high degree of similarity (85–100 %). Homologs of the Rpi-R3b, Rpi-amr3 and Rpi-ber1 genes have been identified in PCPS for the first time. An analysis of polymorphism of nucleotide and amino acid sequences has been carried out for 15 R genes. The differences in frequencies of substitutions in PCPS have been demonstrated by analysis of R genes, the reference sequences of which have been identified in different species. For all the studied NBS-LRR genes, the proportion of substituted amino acids in the LRR domain exceeds this figure for the NBS domain. The potential prospects of using PCPS as sources of resistance to Verticillium wilt have been shown.

Late blight resistance in wild potato species—Resources for future potato (Solanum tuberosum) breeding

et al. 2022

View full text Add to dashboard Cite

Late blight remains the most devastating disease in potato cultivation. The best protection against this disease could be achieved by durably resistant cultivars, but these do not exist at present. To advance resistance breeding, the search for resistant wild potato species and the characterization of their resistance is important. There have recently been a number of new developments in this area. For this reason, all wild potato species known to the authors in which resistance has been found to date are listed in this article with their respective genes and QTL. Lastly, an overview is given, how these new resistance sources can be used for future resistance breeding.
