Mechanisms of starch structural reorganization induced by freeze-thaw techniques under mild osmotic stress.

International journal of biological macromolecules | 2026-Jun-19

This study investigates the structural and physicochemical changes in potato starch caused by different freezing methods and osmotic stress thawing. The findings demonstrate how these techniques affect granule fragmentation, crystallinity, and rheological properties, offering methods to modify potato starch functionality for food science applications.

The role of cultivation technology in shaping the health-promoting potential of potato tubers (Solanum tuberosum L.).

Scientific reports | 2026-Jun-19

This study investigates how various agronomic practices, such as nitrogen fertilization and irrigation, influence the polyphenol content and antioxidant capacity of two potato varieties (Solanum tuberosum). The findings highlight that genotype is a primary factor in determining health-promoting compounds, with the variety 'Gardena' showing significantly higher nutritional potential.

Analysis of differential gene expression in potato leaves exposed to low dose ionizing radiation.

Functional & integrative genomics | 2026-Jun-20

This study performs transcriptomic analysis on potato plants exposed to low-dose gamma radiation, identifying thousands of differentially expressed genes related to DNA repair and metabolism. The findings highlight specific dose-dependent gene responses and phenotypic changes, offering potential for developing stress-tolerant potato varieties or radiation-detecting phytosensors.
