This study uses transcriptomic analysis of three potato cultivars to identify candidate defense genes against Spongospora subterranea (powdery scab) and Potato mop-top virus. The researchers identified 80 high-confidence genes, including immune receptors and phytohormone-related genes, providing potential targets for molecular breeding and genetic improvement in potatoes.
This paper develops a new genetic toolset for Pectobacterium brasiliense, a major pathogen causing potato soft rot and blackleg. The system enables markerless gene deletion and high-density transposon mutagenesis, facilitating the identification of key virulence factors and functional genomics research to better understand potato disease mechanisms.
This study investigates the interfacial adsorption and emulsion stability of potato protein (POPI) under various heat treatments. The research demonstrates how preheating temperatures and protein concentration influence droplet coalescence and adsorption rates, providing insights into the food science applications of potato-derived proteins.
This study investigates the wound healing capacity and suberin barrier formation across different cellular regions of potato tubers, specifically comparing the cortex, outer medulla, and inner medulla. The research demonstrates that the inner medulla exhibits faster suberization and higher metabolic activity related to phenylpropanoid regulation, with responses being cultivar-specific.
This study investigates the synergistic effects of BAP and zinc nanoparticles on the in vitro growth and antioxidant enzyme activities of Solanum tuberosum. The results demonstrate that low concentrations of these supplements enhance shoot proliferation and boost the plant's antioxidant defense system, while higher concentrations inhibit growth.
This study utilized genome-wide association analysis (GWAS) on 288 tetraploid potato accessions to identify genomic regions and candidate genes associated with tuber micronutrient concentrations (Fe, Zn, Cu, and Mn). The researchers identified 16 significant marker-trait associations, including a major locus for manganese content, providing molecular tools for biofortification in potato breeding programs.
This study evaluates the virulence of diverse Peruvian and U.S. potato cyst nematode populations against a panel of potato genotypes and resistance sources. The findings reveal that Andean populations possess a broader virulence spectrum than U.S. populations, potentially overcoming current resistance genes like H2 and H3, which emphasizes the need for diverse resistance gene pyramiding in potato breeding.
This study evaluates the drought response of Solanum brevicaule, a wild relative of the cultivated potato, by analyzing physiological, anatomical, and yield-related traits across different genotypes. The findings provide valuable phenotypic data to support the breeding of drought-resilient potato cultivars using wild germplasm.
This study investigates the synergistic effects of humic acid and nano-magnesium oxide on mitigating drought stress in Solanum tuberosum. The findings indicate that these applications improve potato yield, starch content, and antioxidant defense mechanisms while enhancing soil health under water-limited conditions.
The study identifies StC3H14, a CCCH-type zinc finger transcription factor in potato, as a key regulator that enhances cold tolerance by directly activating the CBF-dependent signaling pathway. Overexpression of StC3H14 leads to improved survival rates and higher tuber yields under chilling conditions, demonstrating its potential for potato crop improvement.
