This study evaluates various alternative proteins for their functional properties in meat analogues, identifying potato protein as the most promising candidate due to its superior emulsifying activity and high gel strength. The research highlights the potential of potato-derived proteins in food science applications to improve the juiciness and texture of plant-based products.
This study genotypes the oldest known specimen of Phytophthora infestans, the pathogen responsible for potato late blight, collected during the 1845 European outbreaks. Using DNA extraction and microsatellite genotyping, the researchers identified the sample as the FAM-1 genotype, providing historical insights into the genetic lineage of the pathogen that caused the Great Famine.
This study evaluates the antioxidant potential and phytochemical profile of the purple-fleshed potato cultivar Vitelotte Noire (Solanum tuberosum) peels. Using metabolomic analysis, the research identifies high concentrations of anthocyanins and phenolics, supporting the use of potato by-products for nutraceutical and functional food applications.
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.
