This study investigates the population genetics and fungicide sensitivity of Rhizoctonia solani AG-3 subgroups, including the PT subgroup responsible for potato black scurf in China. The research reveals that the potato-infecting PT subgroup exhibits high gene diversity and clonal reproduction, likely spreading through contaminated seed tubers, and remains generally sensitive to fludioxonil.
This study utilizes integrated transcriptomics and metabolomics to investigate the molecular response of the potato cultivar Cooperation 88 to Potato virus S (PVS) infection. The results identify key differentially expressed genes and metabolites, highlighting the central role of the phenylpropanoid and flavonoid biosynthesis pathways in potato antiviral defense.
This study analyzes deleterious genetic variants across 502 potato accessions to understand the 'hidden cost' of domestication and its impact on hybrid breeding. The researchers propose a progenitor-assisted genomic framework to purge deleterious alleles, facilitating the transition from clonal tetraploid to more efficient diploid hybrid potato breeding.
This study presents the first nuclear genome population analysis of Synchytrium endobioticum, the causal agent of potato wart disease, using a robust SNP discovery strategy. The research identifies three distinct genetic phylogroups and explores the evolution of the AvrSen1 effector, providing insights into pathogen virulence and aiding in global surveillance and quarantine efforts.
This study details the development and regulatory approval of Kal91.3, a genetically engineered potato line created by suppressing the vacuolar invertase (VInv) gene via RNAi to prevent cold-induced sweetening. The resulting tubers maintain low reducing sugar levels during long-term cold storage, ensuring high-quality chip color and improved storage stability compared to the parental Kalkaska variety.
This study develops a novel silica-based sorbent using click chemistry for the efficient extraction of polar analytes. The material was successfully applied to detect acrylamide, a toxic compound formed during high-temperature processing, in potato chips. This analytical method provides a rapid and sensitive tool for food safety monitoring in potato-derived products.
This study evaluates the effects of sodium metabisulfite (SM) treatment on the quality, enzymatic browning, and bacterial dynamics of fresh-cut potatoes during chilled storage. The findings demonstrate that a 0.3% SM treatment effectively delays browning by inhibiting key enzymes (PPO, POD, and PAL) and helps maintain the texture and weight of the potatoes.
This study develops a 3-decen-2-one/hydroxypropyl-β-cyclodextrin inclusion complex to improve the stability and solubility of 3-decen-2-one, a natural potato sprout suppressant. When applied during potato storage, the complex effectively inhibited sprouting, reduced weight loss and respiration rates, and preserved potato quality.
This review summarizes recent advances in plant cytosolic and plastidic pyruvate kinases, focusing on their structure, regulation, and physiological roles. It includes phylogenetic, motif, domain, and promoter cis-element analyses of pyruvate kinase genes from several crops, including potato (Solanum tuberosum), to support crop improvement and stress-resilient breeding.
This study investigates the surface properties, wettability, and functionality of extruded potato starch films enriched with edible oils. The research evaluates how oil type and concentration affect the films' physical characteristics and stability, aiming to improve their application in the food and pharmaceutical industries.
