This study investigates the effects of organic acids on the fermentation quality of purple potato wine, specifically focusing on reducing methanol and higher alcohol levels. Using transcriptome analysis and enzyme activity assays, the research identifies how organic acids modulate gene expression related to ester synthesis and alcohol formation to improve the wine's flavor and safety.
This study evaluates heavy metal and selenium concentrations in staple crops, including potatoes, within a selenium-endemic region of China. It identifies potatoes as having the highest contamination levels among the crops studied, significantly contributing to cumulative dietary health risks.
This study presents survey data from 4,684 European farmers across eight major crops, including potatoes, regarding the adoption of Integrated Pest Management (IPM) practices. The dataset identifies socio-economic, behavioral, and environmental factors that influence the uptake of low-pesticide strategies and crop protection measures in potato cultivation.
This study investigates the distribution and composition of starch granule-associated proteins (SGAPs) in potato and maize starches using sequential α-amylase hydrolysis. The researchers found that granule-bound starch synthase (GBSS) is the dominant protein in potato starch, exhibiting a concentric ring distribution. Additionally, the study revealed that smaller potato starch granules contain higher levels of soluble starch synthase and GBSS, but less α-glucan water dikinase compared to larger granules.
The study develops highly efficient cytosine base editors (CBEs) for potato (Solanum tuberosum) by optimizing cytidine deaminases, promoters, enhancers, and chromatin-modulating strategies. The optimized base editor, RF-Sdd7-HNHN, significantly increased editing efficiency and was successfully used to simultaneously edit StALS1 and StALS2 genes to generate herbicide-resistant potato germplasm.
This study utilizes CRISPR/Cas9 technology to knock out the StPain-1 gene, which encodes vacuolar invertase, in Solanum tuberosum cv. Fritella. The resulting edited potato lines showed reduced vacuolar invertase activity and lower hexose accumulation during cold storage, leading to lighter-colored chips. These plants represent a promising genetic resource for breeding potato varieties resistant to cold-induced sweetening.
This study evaluates toxic trace-metal contamination in soils and vegetables in Bangladesh, finding that potatoes accumulate significant levels of heavy metals. The dietary intake of these contaminated potatoes was shown to pose both carcinogenic and non-carcinogenic health risks to consumers.
This review examines the genetic mechanisms of inbreeding depression in diploid potatoes, focusing on the accumulation of deleterious mutations due to clonal propagation. It evaluates various breeding strategies, such as genomic selection and CRISPR-Cas9, to mitigate genetic load and facilitate the development of homozygous inbred lines for hybrid potato breeding.
This study investigates how the number of hydroxyl groups in polyphenols affects their interactions with potato starch and whole potato flour matrices. The research demonstrates that the complexity of the whole potato flour matrix alters polyphenol crystallization and structural properties, providing insights into the food science and nutritional characteristics of potato-based systems.
This study utilizes CRISPR/Cas9 to knock out the StGAME9 transcription factor in potato, revealing its critical role in regulating both basal and induced steroidal glycoalkaloid (SGA) biosynthesis. The results demonstrate that loss of StGAME9 significantly reduces SGA levels in tubers and leaves without negatively impacting plant growth, offering a potential strategy for developing safer potato varieties.
