Summary: Wild potato relatives are potential sources of desirable agricultural traits for potato breeding. We described 29 seed accessions of 26 Solanum species from the VIR potato collection and preserved in Poland. The evaluation included resistance to disease, tuber flesh color, enzymatic discoloration, and tuber dormancy. We found valuable potato relatives with resistance, white flesh, and longer dormancy periods.

Summary: The periderm of potato is a significant corky tissue that plays a crucial role in protecting the tuber from pathogens and water loss. Its formation is closely linked to the development and physiological disorders of potato, such as skin injuries and russeting.

Summary: The research revealed the essential role of JAZ1-like-mediated JA signalling in potato tuberization by suppressing tuber initiation and modulating the expression of genes associated with transcriptional regulators, cell cycle, and cytoskeleton. Additionally, the destabilization of StJAZ1-like upon treatment with abscisic acid (ABA) and the partial rescue of the attenuated tuberization phenotype in StJAZ1-like ox plants by ABA treatment were also demonstrated.

Summary: The use of a sprout suppressor is crucial for extending the storage period of potatoes. A comparison between 1,4-dimethylnaphthalene (1,4-DMN) and chlorpropham (CIPC) showed that 1,4-DMN is an effective alternative to CIPC in controlling sprouting and maintaining the quality of potatoes during cold storage. Both inhibitors led to improved starch content, reduced reducing sugar content, and preserved the recommended quality for industrial processing. Furthermore, French fries made from potatoes treated with 1,4-DMN or CIPC showed less browning after frying, indicating the contribution of 1,4-DMN to the quality maintenance of French fries.

Summary: This study found that potato tubers can immediately take up externally supplied glucose-1-phosphate and convert it into maltodextrins. The plastidial glucan phosphorylase is responsible for producing longer maltooligosaccharides in the presence of glucose-1-phosphate. These findings contribute to a better understanding of the role of the plastidial phosphorylase in starch metabolism.

Summary: This study aimed to investigate the effects of irrigation water saving strategies on potato tuber growth and nutritional composition. The results showed that irrigation from tuber initiation up to 50% of tuber growth could improve the nutritional composition of tubers, while irrigation from 50% of tuber growth to the end of tuber growth had similar results to the dry control group.

Summary: This study explores the genetic components of tuber bruising in potatoes through genome-wide and transcriptomic analyses. The findings highlight the role of genetic factors in cellular strength and resistance to physical force, as well as mechanosensing mechanisms. A new visualization method is proposed to integrate and compare the results with previous knowledge on the trait.

Summary: Potato plants respond differently to elevated CO2 and high temperature, with elevated CO2 partially alleviating the inhibition of sink organs by high temperature.

Summary: Different PCA-producing Pseudomonas spp. strains exhibited varying levels of biocontrol activity against Phytophthora infestans in potato tuber bioassays. The quantities of PCA produced did not correlate with biocontrol activity, suggesting the presence of other genetic determinants potentially involved in controlling the pathogen. Genome mining identified siderophores, cyclic lipopeptides, and non-ribosomal peptide synthase and polyketide synthase hybrid clusters as potential factors in the biocontrol of Phytophthora infestans by phenazine-producing pseudomonads.

Summary: Potato is a major staple crop in the Mediterranean Basin, and its yield can be greatly influenced by the environment and genotype. This study evaluated the yield performance of five potato genotypes over four years and three locations in Sicily using AMMI and GGE analyses. The results showed significant genotype x environment interaction, with Arizona and Generosa identified as the most productive and stable genotypes. The ideal environments varied depending on the productive trait, with Acireale being the preferred location for most traits.

Summary: Efficient and eco-friendly techniques for breaking potato tuber dormancy are in high demand. This study evaluates the effectiveness of four dormancy-breaking methods and investigates their impact on endogenous hormone levels. The results show that the use of plant growth regulators is the most effective method for shortening the dormancy period.

Summary: Potato quality characteristics are affected by genotype x environment interaction. AMMI and GGE biplot analyses were used to study GEI in potato quality traits. The results showed that genotype had a significant impact on dry matter, citric acid, DPPH and washability, while environment had a greater effect on total phenolics, vitamin C, reducing sugars and FRAP. Salad Blue was identified as the most suitable genotype for dry matter, total phenolics, vitamin C and FRAP across different environments.
