This study evaluates the nutritional profile, amino acid composition, and antioxidant activity of three potato varieties (Agria, Désirée, and Kennebec) grown in Southern Italy. The findings highlight significant differences in protein and carbohydrate content among varieties, high phenolic levels, and a rich mineral profile, emphasizing their nutritional value.
This study investigates the transcriptomic and phenotypic changes in Solanum tuberosum during paclobutrazol-induced microtuberization. The research identifies key metabolic and signaling pathways, such as gibberellin restriction and starch accumulation, that drive the developmental shift from stolon growth to storage organ expansion.
This study identifies 191 bZIP transcription factor genes in tetraploid potato and characterizes their roles in stress response. Specifically, it demonstrates that StbZIP104 is a nuclear-localized protein that enhances cold tolerance by regulating antioxidant activity and osmolyte accumulation.
This study identifies and analyzes the Glutathione S-transferase (GST) gene family across a pan-genome of 45 diploid potato accessions. It explores the evolutionary characteristics, tissue-specific expression, and responses to abiotic stresses of these genes, highlighting StGST7 as a key candidate for enhancing salt and drought tolerance.
This study evaluates the starch diversity of 137 global potato (Solanum tuberosum) germplasms, analyzing variations in starch content, granule morphology, and molecular structure. The findings provide a basis for breeding programs aimed at developing potato varieties with specific starch properties for industrial and food applications.
This study utilizes low-field nuclear magnetic resonance (LF-NMR) and differential scanning calorimetry (DSC) to examine the gelatinization and retrogradation properties of isolated potato starch compared to potato flour. The research demonstrates how non-starch components like proteins and fibers in potato flour restrict starch swelling and stabilize water distribution during storage, providing insights into the food science of potato-derived products.
This study identifies the potato nucleoskeleton protein StKAKU4 as a susceptibility factor that is targeted and stabilized by the Phytophthora infestans effector Pi22798. The research demonstrates that StKAKU4 negatively regulates plant immunity by modulating vesicle trafficking between the nuclear envelope and endosomal organelles during infection.
This study investigates the impact of various chitosan derivatives on the 'Lady Rosetta' potato variety, focusing on growth, yield, and processing quality. It highlights how chitosan lactate modulates the expression of genes related to enzymatic browning and acrylamide precursors while providing antibacterial protection against major potato pathogens.
This study evaluates the use of myco-synthesized copper oxide nanoparticles (CuONPs) as a sustainable bionanofungicide to manage the potato pathogen Fusarium falciforme. The research demonstrates that CuONPs effectively suppress fungal growth, mitigate disease symptoms, and significantly enhance potato tuber yield and antioxidant enzyme activity.
This study examines the impact of different land-use systems, including a potato monoculture field, on soil fungal communities in the Brazilian Cerrado. The research compares fungal diversity and soil characteristics across native vegetation, cover-cropping, and potato cultivation, identifying core mycobiota such as Fusarium and Trichoderma.
