This study investigates the impact of microwave irradiation on β-amylase structure and kinetics to suppress starch retrogradation in mashed potatoes. The findings demonstrate that microwave pretreatment enhances enzymatic activity and structural flexibility, providing a synergistic approach to improve the texture and shelf life of potato starch-based foods.
This study details an optimized cryopreservation protocol for potato shoot tips using PVS3 droplet-vitrification, achieving a 70% regrowth rate across a large collection of accessions. The improvements focus on enhancing the long-term conservation of potato genetic resources through modifications in propagation, preculture, and rewarming techniques.
This study evaluates the development of biopolymer films using potato starch as a key component, comparing electrospinning and solvent casting techniques. The research demonstrates that electrospun potato starch-based nanofibers exhibit significantly improved mechanical strength, antioxidant properties, and antibacterial activity compared to traditional solvent-cast films.
This study evaluates a multi-technology approach to reduce food waste in the fresh potato supply chain using advanced imaging and sensors to detect internal defects. The research assesses the environmental, social, and economic impacts of redirecting defective potatoes into value-added products like starch and animal feed, demonstrating significant sustainability benefits.
This study investigates how drought stress memory in potato (Solanum tuberosum) can be transmitted from a primed scion to vegetative progeny, affecting tuber yield and photosynthetic efficiency. The research highlights significant changes in gene expression related to metabolic pathways and stress response, though it found that drought-induced DNA methylation patterns were not maintained beyond the second generation.
This study demonstrates that exogenous spermidine (Spd) enhances alkaline-salt stress tolerance in potato (Solanum tuberosum) by enhancing antioxidant defenses, maintaining osmotic balance, and inducing tissue-specific transcriptional reprogramming. RNA-seq and WGCNA identified key pathways including plant hormone signaling and carbon metabolism, along with candidate hub genes (StHK4, StbZIP27, and StERF106) that act as potential regulators of Spd-induced stress adaptation.
This study utilizes integrated proteomics and phospho-proteomics to characterize the molecular defense responses of potato plants to herbivory by the potato tuber moth (Phthorimaea operculella). The researchers identified CDPK2 as a key regulator that enhances herbivore resistance by modulating jasmonic acid and salicylic acid signaling pathways.
This study evaluated and optimized a multi-processor UV-C reactor system to effectively inactivate major potato pathogens, Ralstonia solanacearum and Pectobacterium carotovorum, in surface irrigation water. By combining pre-filtration with an optimized UV-C radiation dose, the system achieved a 4-log reduction in pathogen load and successfully suppressed soft rot development in potato tubers.
This study integrates transcriptomic and metabolomic analyses of a segregating tetraploid potato population to elucidate the regulatory networks underlying starch accumulation. It highlights key transcription factors (AP2/ERF, MYB, bHLH) and structural genes involved in carbon partitioning and starch biosynthesis. These findings offer potential molecular targets for breeding and genetic editing to improve potato starch content.
This study identifies the acyl-ACP thioesterase gene FATA as a key factor associated with drought tolerance in tetraploid potato (Solanum tuberosum). Functional analyses in Arabidopsis and haplotype profiling in potato cultivars demonstrate that FATA regulates cuticle permeability and water stress responses by facilitating fatty acid export for cutin biosynthesis. Additionally, protein structural modeling highlights potential isoform-specific enzymatic activity in potato.
