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.
This study identifies a link between frequent consumption of fried potatoes and an increased risk of metabolic associated fatty liver disease (MAFLD) mediated by acrylamide. It demonstrates that acrylamide disrupts hepatic lipid metabolism and triggers inflammatory responses through the arachidonic acid-PGE2-PPARα signaling axis.
This study investigates the role of exodermal suberin in Solanum tuberosum roots by downregulating the suberin biosynthetic gene CYP86A33. The findings demonstrate that exodermal suberin is crucial for maintaining ion homeostasis and supporting overall plant growth, highlighting its importance as a regulatory barrier for mineral nutrients.
This study investigates a method to rapidly fix transgenic alleles in potato (Solanum tuberosum) and forage rape populations by using herbicide selection. The researchers demonstrated that applying chlorsulfuron to hemizygous plants results in distorted segregation, significantly increasing the proportion of transgenic progeny to achieve homozygosity.
