This study demonstrates that the viral genome-linked protein (VPg) of Potato virus Y (PVY) targets the host transcription factor MYB330 to suppress hydrogen-peroxide-mediated antiviral immunity. By interfering with MYB330's transcriptional repression of Catalase1, the virus promotes H2O2 scavenging and facilitates its own accumulation.
This study investigates how combining genetic selection of diploid potatoes with thermal processing reduces anti-nutritional factors (like solanine) to safe levels while retaining high amounts of beneficial nutrients. Using a zebrafish model, the authors demonstrate that this integrated approach mitigates gut inflammation and growth depression, promoting better growth performance and digestive capacity compared to conventional tetraploid potatoes.
This review explores the interaction between potato (Solanum tuberosum) root exudates and the soil-borne pathogen Verticillium dahliae, the causal agent of Verticillium wilt. It proposes a "germinate-to-exterminate" (G2E) strategy that uses root exudate metabolites to stimulate premature germination of fungal microsclerotia for sustainable disease control.
This study identifies two AP2/ERF transcription factors, StRAP2.7a and StRAP2.7b, that promote stolon and tuber formation in potato (Solanum tuberosum). The researchers demonstrate that these transcription factors regulate trans-zeatin biosynthesis and directly activate the key tuberization-regulatory gene StSP6A. These findings elucidate the molecular mechanisms of potato tuberization and offer potential genetic targets for breeding high-yielding cultivars.
The study introduces a portable diagnostic platform combining RPA-CRISPR/Cas12a and a microneedle patch for the rapid, early-stage detection of Phytophthora infestans in potatoes. The system enables efficient leaf sampling and smartphone-based fluorescence analysis, detecting the pathogen before visible symptoms appear. This technology provides a field-deployable tool for early diagnosis and surveillance of potato late blight.
Researchers used CRISPR/Cas9 to edit the susceptibility gene StDND2 in Solanum tuberosum, resulting in significantly enhanced resistance to late blight (Phytophthora infestans). The edited potato lines showed a 74% reduction in infection rates without visible developmental abnormalities, demonstrating the potential of S-gene targeting for disease resistance.
This study investigates the structural and physicochemical changes in potato starch caused by different freezing methods and osmotic stress thawing. The findings demonstrate how these techniques affect granule fragmentation, crystallinity, and rheological properties, offering methods to modify potato starch functionality for food science applications.
This study investigates how various agronomic practices, such as nitrogen fertilization and irrigation, influence the polyphenol content and antioxidant capacity of two potato varieties (Solanum tuberosum). The findings highlight that genotype is a primary factor in determining health-promoting compounds, with the variety 'Gardena' showing significantly higher nutritional potential.
This study performs transcriptomic analysis on potato plants exposed to low-dose gamma radiation, identifying thousands of differentially expressed genes related to DNA repair and metabolism. The findings highlight specific dose-dependent gene responses and phenotypic changes, offering potential for developing stress-tolerant potato varieties or radiation-detecting phytosensors.
This study evaluates phenotypic and transcriptional responses in the Colorado potato beetle (Leptinotarsa decemlineata), a major potato pest, to investigate potential cross-resistance between imidacloprid and the novel insecticide isocycloseram. The findings indicate emerging phenotypic cross-resistance, though transcriptomic analysis of detoxification genes revealed complex and inconsistent expression patterns across populations.
