This study investigates the distinct interaction patterns between potato starch (compared to corn starch) and various polyphenols, and how these interactions affect starch digestibility and glucose absorption. The findings reveal that potato starch forms non-inclusion complexes with polyphenols that reduce digestive enzyme activity and downregulate glucose transporters (SGLT1 and GLUT2), offering strategies for designing low-glycemic potato-derived foods.
This study investigates how Potato Virus Y (PVY) infection influences the assembly of endophytic microbial communities in potato roots and leaves. It highlights that PVY infection increases deterministic assembly processes, which are further modulated by soil physicochemical properties and primarily affect low-abundance microbial taxa.
This study demonstrates that salicylic acid (SA) signaling is essential for nonhost resistance in potato against the oomycete Phytophthora capsici. By analyzing transgenic plants and transcriptomic data, the researchers identified that SA coordinates defense pathways and metabolic responses, with specific transcription factors like ERF1B and WRKY53 playing key regulatory roles.
This study investigates the use of foliar-applied branched-chain amino acids (valine, leucine, and isoleucine) to mitigate the negative effects of salinity stress on Solanum tuberosum. The research demonstrates that these amino acids enhance potato yield and stress tolerance by increasing proline accumulation, protein content, and antioxidant enzyme activity.
The researchers developed Stomatalia, a deep learning-based platform for automated high-throughput phenotyping of stomata and pavement cells, trained and validated using cultivated and wild potato genotypes. The tool was successfully tested in a potato drought-stress trial, providing a robust method for analyzing epidermal traits relevant to climate-resilient potato breeding.
This study evaluates the use of heat-treated whey powder solutions to inhibit enzymatic browning in fresh-cut potatoes. It demonstrates that treatment at 50°C effectively reduces polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL) activities, preserving color and nutritional quality during storage.
Researchers developed a loop-mediated isothermal amplification (LAMP) assay for the rapid and sensitive detection of the potato cyst nematode Globodera ellingtonae. This molecular tool targets the chorismate mutase gene to differentiate G. ellingtonae from other major potato pathogens like G. pallida and G. rostochiensis, facilitating better regulatory and management decisions.
This study identifies StGATA14 as a positive regulator of drought tolerance in potato (Solanum tuberosum) by enhancing antioxidant defense and osmotic adjustment. Functional analysis using overexpression and RNAi lines shows that StGATA14 improves photosynthetic stability and activates key stress-responsive genes like StSOD and StP5CS.
This study investigates the impact of superheated steam-modified oat insoluble dietary fiber on the pasting, rheological, and retrogradation properties of potato starch. The findings demonstrate that specific concentrations of modified fiber can optimize starch viscosity and structural stability, offering insights for the development of potato starch-based food products.
This study investigates the effects of targeted thermal processing on potato starch-konjac glucomannan composites to improve their structural stability and digestibility. The research demonstrates that heating at specific transition temperatures enhances starch-hydrocolloid interactions, leading to improved pasting properties and increased resistant starch content.
