This study identifies a perillaldehyde-derived compound, Y14, as a potent inhibitor of Potato virus Y (PVY) by targeting the Ser207 residue of the viral coat protein. The compound disrupts the interaction between the viral protein and host factors, effectively impeding the intercellular spread and systemic infection of PVY in plants.
This study investigates the complex interactions between soil physicochemical properties and microbial communities in relation to potato common scab severity across 124 fields in South Korea. While specific microbial taxa like Rhodanobacteraceae and Sphingomonadaceae were associated with different severity levels, the research concludes that disease development is driven by multifaceted interactions rather than a single dominant factor.
This study investigates a novel RNA interference (RNAi) approach to control the potato cyst nematode (Globodera rostochiensis) using nanoclay-based dsRNA delivery. The research focuses on developing biotechnological tools to enhance potato resistance against one of its most significant soil-borne pests.
This study investigates the use of combined ultrasound and high-pressure steam treatments to increase the soluble dietary fiber content in potato pomace. The treatment significantly improved the structural, physicochemical, and functional properties of the fiber, enhancing its potential for use in food applications.
This study investigates the physiological and molecular responses of potato seedlings to nicotine stress using multiomics and molecular docking. The research identifies that while low nicotine levels can promote growth, high concentrations inhibit photosynthesis and activate antioxidant pathways, providing insights into potato cultivation in nicotine-contaminated environments.
This study evaluates the interaction between drought stress and early blight (Alternaria alternata) susceptibility across 44 potato genotypes. The research identifies specific resistant and susceptible genotypes, demonstrating that water stress significantly increases disease severity and reduces yield, providing valuable data for breeding programs focused on multi-stress resilience.
This study investigates the morphological and hormonal changes in potato (Solanum tuberosum) Ri genotypes created via Rhizobium rhizogenes-mediated transformation. By analyzing T-DNA gene expression and hormone profiles, the research identifies genetic mechanisms underlying altered plant architecture and root development, offering potential applications for potato breeding.
This study demonstrates that exogenous melatonin treatment preserves the quality of fresh-cut potatoes by inhibiting browning and softening through the activation of phenylpropanoid metabolism and antioxidant defenses. It also highlights the role of melatonin in regulating gene expression, such as StMYB168, and antagonizing ethylene biosynthesis to maintain cell wall structure and starch content during cold storage.
This study characterizes three potato (Solanum tuberosum) BiP isoforms (StBiP1, StBiP2, and StBiP3) by testing their ability to complement yeast mutants under ER stress. The findings reveal that StBiP3 is a stress-specialized chaperone, identifying it as a potential target for enhancing stress resilience in potato crops.
This study investigates the relationship between polyphenol oxidase (PPO) gene expression and enzymatic browning in purple-fleshed potato cultivars. It identifies specific isoforms, particularly StPPO2 and StPPO8, as key drivers of browning in pigmented potatoes, providing potential targets for improving post-harvest quality.
