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.
This study explores the use of L-asparaginase derived from Pleurotus ostreatus to reduce acrylamide formation in potato chips. The enzyme treatment significantly mitigated acrylamide levels and altered the potato's chemical profile, demonstrating its potential in potato-derived food safety and processing applications.
This study investigates the distribution and genetic diversity of potato viruses across various regions in Russia using de novo genome assembly and phylogenetic analysis. The research highlights the prevalence of recombinant variants of Potato Virus Y (PVY) and mixed infections involving PVM and PVS, providing a basis for developing dsRNA-based control strategies.
This study identifies scabicidin, a metabolite from insect-associated Streptomyces, as an effective control agent against potato scab. Scabicidin inhibits the DNA gyrase of Streptomyces scabies, demonstrating significant efficacy in both pot and field trials compared to commercial bactericides.
