This study performs a genome-wide association study (GWAS) on 200 potato genotypes to investigate the genetic basis of late blight resistance. The researchers identified significant resistance loci on chromosomes 9 and 11, with the chromosome 11 locus containing candidate NBS-LRR genes. These findings provide molecular markers to support marker-assisted selection and pyramiding of late blight resistance in potato breeding programs.
This study identifies StRWA2 as a susceptibility factor in potato (Solanum tuberosum) that negatively regulates NLR-mediated resistance to Phytophthora infestans. StRWA2 recruits the E3 ubiquitin ligase StSNIPER2 to ubiquitinate and degrade NLR proteins, thereby suppressing the plant's immune response. Silencing StRWA2 via RNAi confers resistance to P. infestans without growth penalties, highlighting it as a potential target for breeding disease-resistant potatoes.
This study investigates the impact of spray-induced gene silencing (SIGS) targeting the pathogen Phytophthora infestans on the potato phyllosphere microbiome. The researchers found that applying dsRNA had minimal effects on the native microbial community, supporting SIGS as a safe and targeted disease control method in potatoes.
The study identifies a transcriptional regulatory module in potato (Solanum tuberosum) where StNF-YC9 and StWRKY75 synergistically activate the expression of the purple acid phosphatase gene StPAP10b under low phosphate stress. The cell-wall-localized StPAP10b protein is released into the rhizosphere to enhance root acid phosphatase activity, facilitating the mobilization and utilization of organic phosphorus. This research provides molecular targets for improving phosphorus use efficiency in potato cultivation.
The study introduces a novel 2D-IC-IPAD chromatography system for the sensitive detection of maleic hydrazide, a sprout inhibitor, in complex vegetable matrices including potato. The method achieves high recovery rates and low detection limits, offering an automated, high-throughput platform for food safety monitoring in potato storage and processing.
This study utilizes RNA-seq profiling to investigate the molecular mechanisms underlying multi-stress tolerance (osmotic, salinity, heat, and cold) during potato (Solanum tuberosum) microtuberization. It identifies 2,046 shared differentially expressed genes and highlights the StSP6A-FD tuberigen complex as a central regulatory hub linking tuber development with stress-responsive metabolic and redox pathways. These findings provide a genetic framework for improving potato resilience to combined abiotic stresses.
This study investigates the application of air jet impingement-assisted air frying on French fries and potato wedges to improve nutritional quality. The method significantly reduced oil absorption, lipid oxidation, and acrylamide formation compared to conventional deep-fat frying while maintaining acceptable sensory and textural properties.
This study examines how cell wall permeability in different potato cultivars influences starch digestion by regulating amylase access to the starch granules. The findings demonstrate that varietal differences in cell wall structure and pectin dissolution are key determinants of the digestibility of intact potato cells.
This study investigates the molecular structure and α-amylase hydrolysis patterns of potato starch compared to maize starch. It highlights that potato starch exhibits an 'outside-in' hydrolysis pattern influenced by the specific distribution of starch biosynthesis-related enzymes and amylose content in its outer shells versus inner blocklets.
This study investigates the role of niacin in inhibiting browning in fresh-cut potatoes by regulating ROS-redox homeostasis and pyridine nucleotide levels. It demonstrates that niacin treatment reduces oxidative damage and modulates the expression of key genes like StPPO and StG6PDH to maintain post-harvest quality.
