“…It involves the specific recognition of pathogen-derived molecules (effectors) by intracellular receptors, known as resistance proteins (R) that results in disease resistance [39]. In potato, dominant R genes can provide two main types of resistance against PVY: ER is conferred by Ry genes and HR is conferred by Ny genes [40]. Upon recognition, signaling events similar to PTI and ETI responses to other pathogens are triggered.…”

“…Phureja, conferring resistance to PVY o , PVY NTN , and PVY N-Wi strains [80]. The introduction of R genes into cultivated potato has shown to confer durable resistance against several PVY strains [40,81]; however, the number of potato cultivars carrying Ry-genes is relatively low (see review [40]). Although the phenotypic outcome is the same in all reported cases of extreme resistance (Figure 1), the underlying mechanisms might differ.…”

“…To date, no eIF4E-related, naturally occurring resistance, was found in potato. Although it may exist, it would be difficult to uncover and maintain in breeding programs due to potato polyploidy (reviewed by [40]). Therefore, in potato, this type of resistance to PVY O , PVY N and PVY NTN , was established by heterologous expression of pepper eIF4E or engineering the existing eIF4E gene [98,99].…”

Potato virus Y (PVY) is the most economically important virus affecting potato production. PVY manipulates the plant cell machinery in order to successfully complete the infecting cycle. On the other side, the plant activates a sophisticated multilayer immune defense response to combat viral infection. The balance between these mechanisms, depending on the plant genotype and environment, results in a specific outcome that can be resistance, sensitivity, or tolerance. In this review, we summarize and compare the current knowledge on molecular events, leading to different phenotypic outcomes in response to PVY and try to link them with the known molecular mechanisms.

“…Extreme resistance to PVY was introgressed to commercial potato cultivars from three different wild Solanum spp. In the European cultivars, resistance originates mostly from S. stoloniferum (Ry sto ) and is not yet overcome (Valkonen et al 2017). Therefore, we set out to clone Ry sto using dihaploid clone (dH) Alicja, which has PVY resistant S. stoloniferum in its ancestry.…”

Summary Potato virus Y (PVY) is a major potato (Solanum tuberosum L.) pathogen that causes severe annual crop losses worth billions of dollars worldwide. PVY is transmitted by aphids, and successful control of virus transmission requires the extensive use of environmentally damaging insecticides to reduce vector populations. Rysto, from the wild relative S. stoloniferum, confers extreme resistance (ER) to PVY and related viruses and is a valuable trait that is widely employed in potato resistance breeding programmes. Rysto was previously mapped to a region of potato chromosome XII, but the specific gene has not been identified to date. In this study, we isolated Rysto using resistance gene enrichment sequencing (RenSeq) and PacBio SMRT (Pacific Biosciences single‐molecule real‐time sequencing). Rysto was found to encode a nucleotide‐binding leucine‐rich repeat (NLR) protein with an N‐terminal TIR domain and was sufficient for PVY perception and ER in transgenic potato plants. Rysto‐dependent extreme resistance was temperature‐independent and requires EDS1 and NRG1 proteins. Rysto may prove valuable for creating PVY‐resistant cultivars of potato and other Solanaceae crops.

The cultivated potato ( Solanum tuberosum L.) is known to be infected by at least 40 viruses. Viruses pose a continuing threat to potato production through yield losses and degrading stocks of seed tubers. Some viruses can be controlled by crop management practices, but the most effective and environmentally beneficial method is through host resistance. Climate change is expected to increase virus disease incidence; however, developments in plant breeding technologies to breed resistant cultivars together with integrated management practices show much potential to control existing and emerging virus diseases. Key Concepts The most economically important viruses of potato. Control of virus disease incidence in potato production systems. Virus resistance mechanisms. Methods of virus detection and identification. Future threats to potato from climate change.
