The study demonstrates the use of long-read RNA-seq to reduce bias in allele and gene expression counts, using Solanum tuberosum as an autopolyploid case study. It provides recommendations for improving allele assignment accuracy, such as mapping to personalized genomes and tracking multimapping reads. These methodologies are highly relevant for potato functional genomics and transcriptomic analyses.
This study investigates the effects of different polysaccharides on the stability and gel characteristics of Pickering emulsions stabilized by potato-soy protein composite nanoparticles. The findings demonstrate that incorporating polysaccharides like pullulan and κ-carrageenan improves the freeze-thaw stability, water retention, and mechanical strength of these potato-protein-based emulsion gels, aiding the development of plant-based fat substitutes.
The study evaluated fifteen potato (Solanum tuberosum) genotypes for resistance to the potato tuber moth (Phthorimaea operculella). Resistance was positively correlated with higher leaf trichome density and length, as well as elevated concentrations of glycoalkaloids and phenolic compounds. These resistant genotypes and associated traits can serve as valuable resources for future potato breeding programs.
This study details the enzymatic production of galacto-oligosaccharides (GaOS) from potato galactan using an endo-β-1,4-galactanase. The resulting potato-derived GaOS demonstrated high gastrointestinal stability, selective prebiotic activity by promoting beneficial gut bacteria, and concentration-dependent antioxidant properties, indicating their potential as functional food ingredients.
This study performs a comparative physiological, transcriptomic, and metabolomic analysis of two potato cultivars with contrasting dormancy lengths during storage. The researchers identified key metabolic pathways and candidate genes, including those involved in cysteine/methionine metabolism, phenylalanine metabolism, and zeatin regulation, that coordinate tuber dormancy release and sprouting.
This paper is a correction to a study identifying natural resistance in potatoes triggered by the recognition of the Phytophthora infestans effector gene Avr3aEM. The research focuses on understanding the genetic mechanisms of late blight resistance in potato cultivars.
This study investigates the population genetics and fungicide sensitivity of Rhizoctonia solani AG-3 subgroups, including the PT subgroup responsible for potato black scurf in China. The research reveals that the potato-infecting PT subgroup exhibits high gene diversity and clonal reproduction, likely spreading through contaminated seed tubers, and remains generally sensitive to fludioxonil.
This study utilizes integrated transcriptomics and metabolomics to investigate the molecular response of the potato cultivar Cooperation 88 to Potato virus S (PVS) infection. The results identify key differentially expressed genes and metabolites, highlighting the central role of the phenylpropanoid and flavonoid biosynthesis pathways in potato antiviral defense.
This study analyzes deleterious genetic variants across 502 potato accessions to understand the 'hidden cost' of domestication and its impact on hybrid breeding. The researchers propose a progenitor-assisted genomic framework to purge deleterious alleles, facilitating the transition from clonal tetraploid to more efficient diploid hybrid potato breeding.
This study presents the first nuclear genome population analysis of Synchytrium endobioticum, the causal agent of potato wart disease, using a robust SNP discovery strategy. The research identifies three distinct genetic phylogroups and explores the evolution of the AvrSen1 effector, providing insights into pathogen virulence and aiding in global surveillance and quarantine efforts.
