This study evaluates the response of six potato (Solanum tuberosum) cultivars to potassium fertilization under drought stress, identifying significant genotypic differences in yield and starch content. The researchers classified the cultivars based on their potassium efficiency and drought tolerance, highlighting cultivar 'SY-2' as a valuable genetic resource for future breeding programs.
This study investigates the role of the StABI5-StCAT1 module in regulating potato resistance to early blight caused by Alternaria solani. The authors demonstrate that StCAT1 acts as a positive regulator of resistance by modulating hydrogen peroxide (H2O2) levels and antioxidant enzyme activities. Furthermore, the transcription factor StABI5 was identified as an upstream activator of StCAT1, providing potential genetic targets for breeding disease-resistant potatoes.
This study evaluates the viscoelastic properties and cellular structure damage of Bellarosa potato tissue under various deformation velocities using stress relaxation tests. The findings describe how loading conditions affect water movement and mechanical behavior in potato tubers, which is relevant to potato food science and post-harvest handling.
This study optimized wet-process starch extraction from rejected Solanum tuberosum (Pastusa variety) using a Box-Behnken design. Under optimal conditions (40 °C, 1:4 w/v ratio, and 3% citric acid), rejected-grade tubers yielded significantly more starch than standard-grade tubers. The extracted starch was validated as native amylose-rich starch, highlighting the potential of rejected potatoes for circular-economy starch recovery.
This study evaluates the use of choline dihydrogencitrate (CCT) as a plasticizer for potato starch-based films. The results show that CCT disrupts the crystalline structure of potato starch, enhancing film flexibility and reducing moisture sensitivity, which is promising for packaging applications.
This study investigates the dissolution and esterification of potato starch using environmentally friendly water-modified deep eutectic solvents (DESs). The water-containing DES showed high dissolution efficiency at mild temperatures, successfully disrupting the starch's crystalline structure and allowing for efficient chemical modification without additional catalysts.
This study describes the fabrication and characterization of starch granular hydrogels using ethanol-annealed potato starch. The resulting hydrogels exhibited significantly improved mechanical properties, crystallinity, and 3D printing performance compared to traditional potato starch hydrogels, offering a new method for developing starch-based biomaterials.
This study develops and validates a rapid, green extraction and UHPLC-MS/MS method for the simultaneous determination of glycoalkaloids and their aglycones in Solanaceae-based baby foods, including those containing potato. The method was successfully applied to commercial infant food samples, highlighting the variability of these toxic compounds and the importance of monitoring potato-derived ingredients for food safety.
This study investigates genomic constraint and hypervariability in elite tetraploid potato breeding lines using GERP scores to identify sites under selection. It explores the relationship between genetic load and phenotypes, finding that hypervariable sites can improve genomic prediction accuracy for yield, offering insights for molecular breeding strategies in tetraploid potatoes.
This study utilizes a multiplexed CRISPR/Cas9 system to knock down the beta-carotene hydroxylase (BCH) gene in potato, resulting in a significant reduction of BCH transcripts. The genome-edited potato lines showed a substantial increase in beta-carotene levels in the tubers, providing a potential strategy for biofortification to address Vitamin A deficiency.
