This study reveals how the effector AVRcap1b from the potato late blight pathogen Phytophthora infestans suppresses host immunity by blocking the assembly of a helper NLR resistosome. By structurally characterizing the interaction, the researchers show that the effector stabilizes a stalled intermediate of the immune receptor. These findings provide crucial insights into the molecular mechanisms of potato pathogen virulence and host immune evasion.
This study identifies and characterizes stress-responsive chitinase genes in potato under drought and disease conditions using RNA-seq, molecular docking, and qRT-PCR. The findings reveal distinct expression patterns and binding affinities among different chitinase classes, highlighting their roles in potato defense mechanisms and abiotic stress tolerance.
This study evaluates the use of ozone-modified potato starch combined with κ-carrageenan as a gelatin alternative in dairy desserts. The researchers optimized the formulation to achieve textural, sensory, and rheological properties comparable to gelatin-based controls. The findings demonstrate that modified potato starch can serve as an effective, environmentally friendly gelling agent in food science applications.
This study evaluates extraction methods for potato trypsin inhibitor (PTI) from processing wastewater, identifying acid precipitation-salting out as the most effective technique for achieving high purity and functional stability. The research highlights the potential of PTI as a bioactive ingredient, contributing to the sustainable valorization of potato-derived industrial byproducts.
This study investigates the optimization of LED lighting parameters to improve potato minituber production in controlled environments. It integrates physiological yield assessments with molecular analysis to understand the genetic or metabolic responses of potato plants to specific light spectra.
This paper examines the long-term impact of intensive agricultural selection and genetic improvement on the nutritional composition of various crops, including potatoes. It highlights a potential 'dilution effect' where increased yields correlate with declines in certain micronutrients, providing important context for future potato breeding and functional genomics research.
This study reports the synthesis of N-alkylated hypoxanthine derivatives and evaluates their antimicrobial efficacy against key potato pathogens, specifically Streptomyces sp. and Rhizoctonia solani. The findings identify specific derivatives with potential for developing treatments to manage these significant potato diseases.
This study evaluates tuber and starch characteristics in diploid potato lines and their hybrids, comparing them to tetraploid varieties. The research highlights significant variations in tuber yield, source-sink relations, and starch granule morphology, demonstrating the utility of diploid breeding material for investigating the genetics of metabolic and quality traits in potatoes.
This study identifies that the potato blue light receptor Stphot2 and the susceptibility factor StNRL-30 negatively regulate resistance to Phytophthora infestans by promoting the degradation of the mitochondrial protein StPRXIIF. The research elucidates a molecular mechanism where blue light signaling modulates potato immunity through the stability and translocation of key immune regulators.
This study evaluates the physicochemical properties and stability of oil-in-water emulsions using potato starch as a key comparative material. It investigates how the amylose/amylopectin ratio of potato starch influences droplet distribution, zeta-potential, and the formation of gel networks when combined with soy protein isolate.
