This study identifies 85 MAPKKK genes in potato (Solanum tuberosum) and characterizes the function of StMAPKKK44. Overexpression of StMAPKKK44 in potato plants enhances tolerance to salt and drought stress by improving antioxidant defense and osmotic balance. The findings suggest StMAPKKK44 is a promising target for breeding stress-resilient potato cultivars.
This study evaluates the resistance of four potato (Solanum tuberosum) cultivars to the aphid pest Myzus persicae using demographic life tables, settling preferences, and field trials. The results identify Evely Lucette as a highly susceptible host and Lucinda V7 as a relatively resistant cultivar. These findings provide valuable insights for breeding aphid-resistant potato cultivars and improving pest management strategies.
This study investigates the impact of temperature on the life-history traits of the aphid Myzus persicae and its transmission efficiency of potato virus Y (PVY) in potato crops. The researchers found that temperature significantly affects aphid development and fecundity, with PVY transmission efficiency peaking at 20 °C. These findings are crucial for predicting PVY spread and developing localized management strategies to protect potato production.
This study evaluates the use of potato peels as a carbon substrate for producing hydrolytic enzymes from a Bacillus species. The resulting enzyme mixture was successfully used to saccharify pretreated potato peel waste into glucose, which was then fermented to produce ethanol.
This study investigates how foliar infection of potato with Phytophthora infestans (late blight) affects the rhizosphere and soil bacterial communities of two cultivars with differing sensitivity. The researchers observed cultivar-specific shifts in the microbiome and isolated bacterial strains with biocontrol potential against the pathogen. The findings suggest that resistant potato cultivars may harbor specific microbiota that contribute to pathogen inhibition.
This study evaluates the performance of different ITS markers (ITS1, ITS2, and full-length ITS) for profiling fungal and oomycete communities in potato leaf and root tissues. The findings show that marker choice significantly influences observed community composition, with ITS2 performing better for leaves and full-length ITS for roots. The research suggests combining complementary markers for a more accurate representation of the potato microbiome.
This study utilizes untargeted metabolomics to analyze metabolic changes in potato seed tubers of four cultivars during storage at different temperatures. The researchers identified cultivar-specific metabolic profiles and observed significant shifts in primary and secondary metabolites, such as reducing sugars and glycoalkaloids, associated with storage duration and temperature. These findings contribute to a better understanding of the metabolic dynamics and physiological aging of potato tubers.
This review summarizes the low-temperature response and regulatory mechanisms of major crops in northern China, specifically including potato. It focuses on the key genes and adaptive strategies involved in cold tolerance, providing a theoretical basis for breeding cold-tolerant potato varieties.
This review paper discusses the molecular mechanisms of self-incompatibility in diploid potatoes (Solanum tuberosum), focusing on key genes like the S-locus inhibitor. It outlines emerging technologies such as genome editing and haploid induction to overcome self-incompatibility and accelerate diploid hybrid breeding.
This study presents an optimized and validated HPLC-DAD method for quantifying steroidal glycoalkaloids (α-solanine and α-chaconine) in potato tubers. The method was applied to potato breeding lines to assess genotype-dependent variations, providing a sustainable analytical tool for food safety monitoring and potato breeding programs.
