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.
This study utilizes comparative transcriptome and metabolome profiling to identify tissue-specific metabolic pathways in potato flesh and skin, focusing on nutrient storage and defense mechanisms. The research highlights key candidate genes involved in starch, flavonoid, and glycoalkaloid biosynthesis, providing molecular targets for breeding potatoes with enhanced nutritional quality and lower toxicity.
This study establishes a rapid and efficient in vivo hairy root induction system for potato using the RUBY reporter gene as a visible marker. The method achieves high transformation and CRISPR/Cas9 editing efficiencies, providing a robust tool for functional genomics and genetic improvement in Solanum tuberosum.
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.
