This study investigates how the Phytophthora infestans effector Pi22798 exploits the potato StKNOX3-StHUB1/2 complex to manipulate histone monoubiquitination and suppress defense gene expression. The findings reveal a mechanism of epigenetic reprogramming that increases potato susceptibility to late blight, providing insights into host-pathogen interactions at the molecular level.
This paper investigates the genetic diversity of the HYP1 locus in potato cyst nematodes, which are major agricultural pests of Solanum tuberosum. By testing the hypothesis of developmentally-programmed mutations, the study provides critical insights into the evolutionary mechanisms used by these pathogens to adapt to their potato hosts.
This study evaluates the moisture sorption behavior and water activity of potato crisps and digestive biscuits using a novel measurement method. The findings demonstrate that the frying process does not significantly alter the sorption properties of potato crisps, providing key thermodynamic data to optimize industrial drying and packaging processes.
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.
