This study describes the development of a highly sensitive electrochemical aptasensor for detecting acrylamide in potato chips. The sensor utilizes a ferrocene-labeled DNA aptamer within liposomes to provide a stable and selective method for monitoring this harmful byproduct in potato-derived food products.
This study investigates how varying ratios of butter and whey protein influence the water binding, structural consolidation, and texture of 3D-printed foods made from potato starch. The research highlights that specific formulations optimize water distribution and macromolecular interactions, leading to more compact microstructures and improved textural properties.
This study investigates the use of RNA interference (RNAi) to control Tuta absoluta, a major pest of potato and other solanaceous crops. The research demonstrates that oral administration of bacterially-produced dsRNA via potato foliage effectively reduces target gene expression and increases larval mortality, highlighting a potential spray-induced gene silencing strategy for crop protection.
This paper describes a 'domain plug-in' engineering strategy to enhance potato (Solanum tuberosum) resistance against late blight. By swapping functional domains within NLR resistance genes identified through genomic analysis, researchers aim to develop crops with broader and more durable immunity.
This study evaluates the impact of various potato vine-kill methods on soil-borne fungal pathogen levels, Potato Virus Y (PVY) incidence, and tuber yield. The findings suggest that mechanical vine-kill techniques, such as pulling and flailing, can reduce soil pathogen DNA levels compared to chemical desiccation, potentially aiding in disease management.
This study identifies a significant increase in the human salivary amylase (AMY1) gene copy number in Indigenous Andean populations, linked to the high-starch diet following potato domestication approximately 10,000 years ago. It provides evolutionary context for the nutritional impact and historical significance of potato cultivation on human genetics.
This study describes a green and efficient method for producing amorphous granular potato starch using microwave-assisted ethanol treatment. The research characterizes the resulting changes in starch crystallinity, morphology, and digestibility, providing insights into potato-derived food science and starch modification.
This research demonstrates that engineering plants with microbial-type terpene synthase-like (MTPSL) genes can enhance resistance against the Colorado potato beetle and fungal pathogens. The study uses Nicotiana benthamiana to show that these genes produce novel sesquiterpenes that suppress pest growth and inhibit Fusarium oxysporum, providing a potential strategy for potato crop improvement.
This study identifies a common genetic basis for virulence in the potato cyst nematode Globodera pallida against the GpaVvrn resistance gene across Western European potato populations. The researchers developed a diagnostic AS-qPCR assay based on a specific SNP (T173N) to monitor virulence levels, providing a tool for sustainable resistance management in potato production.
This study identifies StWRKY46 as a key transcription factor that enhances drought tolerance in potato by activating the ABA signaling pathway. StWRKY46 directly regulates the expression of the ABA receptor StPYL1, which triggers a signaling cascade leading to stomatal closure and improved water retention.
