This study identifies R8 gene analogs in potato that act as negative modulators of R8-mediated resistance against late blight (Phytophthora infestans). These analogs suppress immune responses by disrupting effector recognition and interfering with the helper NLR protein NRC2, revealing an endogenous regulatory mechanism that helps prolong the durability of disease resistance.
This study demonstrates a strategy to balance growth and immunity in potato (Solanum tuberosum) by utilizing a humidity-inducible promoter to drive a late blight resistance gene. The resulting transgenic potato lines achieved robust late blight resistance under high relative humidity while avoiding the growth suppression and tuber yield penalties typically associated with constitutive resistance gene overexpression.
This study evaluates the antioxidant and antimicrobial properties of potato peel powder, combined with pomegranate peel powder, as a natural preservative in refrigerated chicken meatballs. The findings show that incorporating potato peels enhances cooking yield, sensory acceptability, and oxidative stability during storage, demonstrating the potential of potato processing byproducts in food science applications.
This study provides a comprehensive time-resolved transcriptomic and morphological analysis of potato (Solanum tuberosum cv. Désirée) stolon initiation from basal axillary buds. It identifies key developmental stages and gene expression patterns associated with the transition from bud to subterranean stolon, offering a valuable framework for understanding potato developmental biology.
This study identifies the StBIN2 gene in potato (Solanum tuberosum) and demonstrates that its overexpression enhances salt stress tolerance. The research shows that StBIN2 regulates antioxidant enzyme activity and reduces oxidative stress markers, providing a potential target for improving potato resilience to saline environments.
This study evaluates the impact of various organic acids on the stability of phenolic compounds and antioxidant activity in red- and purple-fleshed potato cultivars during the production of dehydrated grits. The findings demonstrate that the effectiveness of these acids is cultivar-dependent, providing valuable insights for optimizing the processing of colored-flesh potatoes to maintain nutritional quality.
This study evaluates the total phenolic content in the peel and flesh of four potato cultivars across different seed propagation stages. The findings highlight that phenolic concentrations are significantly higher in the peel compared to the flesh and suggest that potato peels are a valuable source of bioactive compounds for further research.
This study investigates the modification of potato starch through hydrothermal and chemical processes to enhance its utility as a carrier matrix for polyphenolic compounds. The research demonstrates that specific modifications, such as citric acid esterification and cationization, improve the thermal stability and structural properties of potato starch for controlled drug release applications.
This study evaluates potato germplasm for resistance to potato cyst nematodes (Globodera spp.) using marker-assisted selection and field validation. The researchers identified five highly resistant potato accessions and confirmed the effectiveness of the H1 resistance gene against G. rostochiensis.
This review paper highlights the application of CRISPR/Cas-mediated genome editing technologies across key Solanaceae crops, including potato. It synthesizes recent progress in targeted genetic modifications to enhance disease resistance, abiotic stress tolerance, and nutritional quality, while discussing current technical limitations and future breeding opportunities.
