This study investigates the role of protein tyrosine nitration in potato immunity against Phytophthora infestans, identifying β-1,3-glucanase as a key target. The research demonstrates that peroxynitrite-mediated nitration inhibits the enzyme's activity, suggesting that this post-translational modification acts as a regulatory mechanism in the potato's defense response.
This study evaluates the impact of varying phosphorus and potassium fertilizer rates on the yield, yield components, and nutrient accumulation of Solanum tuberosum in Ethiopia. The research identifies optimal fertilizer combinations to maximize marketable tuber yield and improve nutrient status in both shoot and tuber tissues.
This study explores the valorization of potato processing byproducts, such as peels and washing slurries, to create nanostructured additives and thermoplastic starch matrices for bioplastics. The research demonstrates that incorporating these potato-derived nanoadditives significantly improves the mechanical strength and water resistance of the resulting starch-based composite films.
This study investigates the presence and genetic diversity of Aster Yellows phytoplasma strains within the potato leafhopper (Empoasca fabae), a major agricultural pest. The research identifies multiple phytoplasma subgroups carried by the leafhopper, providing insights into the potential role of this insect as a vector for diseases that can significantly impact potato crops.
This study explores engineering the 3'-UTR of Tobacco vein mottling virus (TVMV) to create attenuated mutants for cross-protection strategies. The research demonstrates that the mutant TVMV58 provides effective cross-protection against Potato Virus Y (PVY), a major pathogen affecting potato crops, offering insights into viral resistance mechanisms.
This randomized-controlled trial investigated the effects of a potato fiber and sugar beet pectin supplement on neurocognition and food-reward brain activity in individuals with overweight and prediabetes. The study found that while the fiber supplementation did not significantly alter brain responses to food cues, the overall high-protein, plant-based diet improved memory, psychomotor speed, and satiety.
This paper examines the genetic diversity of the Rychc gene in Solanum chacoense, a wild relative of the potato, and its role in providing resistance to Potato Virus Y (PVY). The research is highly relevant to potato breeding and functional genomics for developing virus-resistant cultivars.
This study identifies natural anti-oomycete compounds from Artemisia lavandulaefolia and Clinopodium repens that effectively inhibit Phytophthora infestans, the pathogen responsible for potato late blight. The extracts demonstrated significant reduction in mycelial growth and tuber pathogenicity, offering potential for developing environmentally friendly fungicides for potato crop protection.
This study demonstrates that introducing the lignin peroxidase gene lip H8 into Agrobacterium fabrum enhances its virulence, colonization ability, and tumorigenesis in potato and other plants. The findings suggest that this modified Agrobacterium strain could serve as a more efficient tool for plant transformation and functional genomics research.
This review explores the molecular mechanisms of Potato Spindle Tuber Viroid (PSTVd) infection and its impact on the transcriptomes, epigenomes, and metabolomes of Solanaceous hosts like potato. It synthesizes current knowledge on viroid structure, systemic movement, and host defense evasion to inform the development of viroid-resistant potato crops.
