This study evaluates human health risks associated with dietary exposure to pesticide residues in potatoes using UPLC-MS/MS and probabilistic modeling. The analysis revealed quantifiable pesticide residues in 35% of tested potato samples, with imidacloprid being the most frequently detected. Cumulative risk assessments indicated that health hazard indices remained within safe limits for most scenarios, though children and adolescents exhibited greater vulnerability to exposure.
This study developed an immunofluorescence assay using a species-specific anti-CENH3 antibody to accurately determine ploidy levels in potato leaf cell nuclei. The method successfully distinguished diploid, triploid, and tetraploid genotypes with results consistent with flow cytometry and root-tip chromosome counting. It offers an accurate, flexible, and reliable alternative for ploidy screening in potato breeding programs.
This review summarizes the genetic and molecular networks governing potato tuber development, highlighting the roles of the tuberigen signal StSP6A, Tuberigen Activation Complex (TAC), and antituberigen factors in both underground and aerial tuberization. It also discusses stolon-to-tuber transition mechanisms, sugar transport via StSWEET-StSUT, and the evolutionary history of modern cultivated potatoes.
This study evaluated qPCR-based quantification of the emerging phloem-restricted pathogens ARSEPH and PHYPSO across 40 potato varieties to assess varietal susceptibility under high pest pressure. The findings demonstrate that ARSEPH load is primarily genotype-dependent and correlates strongly with early symptom expression, canopy senescence, and yield reduction. The authors suggest integrating qPCR-derived pathogen titers into potato breeding programs to select for resistance and yield stability against these vector-borne pathogens.
This study synthesized novel 2-(arylthio)acetophenone derivatives as broad-spectrum tyrosinase inhibitors and evaluated their efficacy across multiple biological systems, including potato juice. Derivatives 5 and 7 demonstrated strong anti-browning activity in potato juice, with derivative 7 exhibiting a highly species-specific inhibition of potato tyrosinase. These findings highlight the potential of these compounds as effective anti-browning agents for potato processing and food science applications.
This study investigates how gellan gum modulates the multiscale assembly, structural uniformity, and mechanical properties of composite gels made from potato protein combined with soybean and pea protein fibrils. The findings provide insights into controlling gel texture and water holding capacity, offering a mechanistic approach for structuring plant-based meat analogues using potato-derived proteins.
This study evaluated a bacterial consortium composed of Stenotrophomonas maltophilia and Serratia liquefaciens as a biocontrol agent against storage soft rot pathogens, including Pectobacterium carotovorum, in root vegetables including potato (Solanum tuberosum). The selected bacterial strains demonstrated cold-temperature growth and high enzymatic activity, showing promise in mitigating post-harvest bacterial diseases during cold storage.
This study utilizes gene editing to mutate the upstream open reading frames of two GDP-L-galactose phosphorylase genes (StGGPs) in potato, successfully increasing tuber vitamin C content and antioxidant activity without compromising yield. Additionally, the authors identify a trade-off where excessive vitamin C accumulation disrupts auxin signaling, emphasizing the importance of fine-tuning gene regulation to balance nutritional enhancement with plant development.
This study identifies RipBR, a YopJ-family effector from Ralstonia solanacearum, as an avirulence factor that suppresses bacterial wilt and restricts pathogen colonization in the wild potato accession Solanum albicans ALB28-1. Functional analysis reveals that RipBR recognition requires key catalytic residues (H158 and C225) to trigger a hypersensitive response and drive auxin-responsive transcriptional reprogramming along with immune gene activation.
This study evaluated the impact of hydrogel-to-oleogel ratios and potato protein isolate (PPI) concentrations on the 3D printing performance and post-heating stability of food-grade bigels. Incorporating PPI improved the dimensional fidelity of printed structures, reduced heat-induced softening, and significantly decreased cooking loss. The results demonstrate the utility of potato protein isolate in developing 3D-printable structured lipids for fat-replacement applications.
