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.
This study explores the development of biodegradable composite films using starch extracted from potato peel waste as a primary material. The research characterizes the physical, thermal, and mechanical properties of these films, demonstrating their potential as eco-friendly alternatives for packaging applications.
This paper introduces LongPolyASE, a computational framework for allele-specific gene and isoform expression analysis in polyploids using long-read RNA sequencing. The tool was validated using autotetraploid potato, demonstrating its ability to identify cis-regulatory variation and haplotype-specific splicing differences in complex genomes.
This review explores post-transcriptional RNA regulation mechanisms, including alternative splicing and small RNA pathways, in Solanaceae crops such as potato. It highlights how these processes mediate light-stress responses and discusses the integration of multi-omics data and machine learning to improve crop resilience and performance.
