This study explores the impact of fortifying potato purée with various algal biomasses to enhance its nutritional and functional properties. It evaluates how different algae species affect the rheological, textural, and structural characteristics of the potato starch matrix compared to traditional hydrocolloids.
This paper examines the evolutionary history and global spread of Phytophthora infestans, the pathogen responsible for potato late blight, using historical herbarium specimens and modern genomic data. It identifies key genetic lineages and tracks changes in virulence genes over time to improve disease surveillance and management strategies for potato crops.
This study evaluated the effects of different biochar particle sizes on potato production, source-sink relationships, and soil micro-environments under varying precipitation patterns in rainfed farmland. Moderate particle size biochar (0.5–2.0 mm) significantly enhanced potato tuber yield, precipitation use efficiency, and nitrogen use efficiency. Furthermore, it effectively reduced soil N2O emissions and nitrogen leaching, offering a sustainable practice for potato cultivation in semiarid regions.
This study investigates the impact of supplemental red-blue LED lighting on potato yield, physiology, and tuber quality in a multi-layer greenhouse system. Using transcriptomic, proteomic, and metabolomic analyses, the authors showed that LED supplementation enhances photosynthetic activity and sugar metabolism while down-regulating stress-responsive pathways and glycoalkaloid levels. These findings provide molecular insights into how artificial lighting optimizes potato growth and nutritional value.
This clinical study evaluated the tolerability and gut microbiome impacts of resistant potato starch (RPS) supplementation in post-bariatric surgery patients. The RPS supplement was well-tolerated and significantly enriched beneficial gut bacteria, particularly members of the genus *Bifidobacterium*. These findings demonstrate the health potential and functionality of potato-derived resistant starch in dietary interventions.
This study investigates how plant genotype and tuber compartments (heel and eye) shape the assembly, stability, and functional specialization of seed potato microbiomes across different environments and years. The authors identified a persistent core microbiome whose compartment-specific functional traits strongly correlate with potato growth-related performance. These findings highlight the role of tuber compartments as ecological filters and identify key microbial targets for enhancing potato resilience and crop yield.
This study identifies the StMYB55/StPYL8-StEXLB1 regulatory module in potato and demonstrates its role in enhancing drought tolerance through stomatal regulation. Overexpression of StEXLB1 or the transcription factor StMYB55 reduces stomatal density and aperture, improving drought resistance by downregulating key stomatal development genes. The findings highlight promising candidate genes for breeding drought-tolerant potato cultivars.
This paper investigates the multifunctional 8K protein of Potato Mop-Top Virus (PMTV) and its role in viral pathogenesis. It explores how PMTV alters host transcriptomes and evades chloroplast-mediated plant immune responses during infection.
This study evaluates the effect of combining nitrogen fertilizer reduction with humic acid application on potato yield, nitrogen use efficiency, and rhizosphere soil microbial communities in semi-arid regions. The findings demonstrate that a 20% reduction in nitrogen combined with liquid humic acid application enhances potato tuber yield and nitrogen uptake by modulating soil nutrient availability and microbial community structure.
This review synthesizes the genetic targets and mechanisms, including StNRAMP, StHMA, and ZIP transporter families, governing cadmium accumulation in Solanum tuberosum tubers. It highlights the integration of low-cadmium accumulating cultivars with agronomic management and CRISPR/Cas9 gene editing to develop cadmium-safe potato production systems.
