Structure-function relationships of potato protein-gum arabic-β-cyclodextrin ternary complexes for emulsion stability and suppression of volatile release from Chinese giant salamander oil.

Food chemistry | 2026-Oct-13

This study investigates the structure-function relationships of ternary complexes composed of potato protein, gum arabic, and β-cyclodextrin for stabilizing emulsions and suppressing volatile release. The findings demonstrate that pH-dependent co-assembly of potato protein within this system enhances thermal stability and emulsifying performance, highlighting its functional utility in food science applications.

MicroRNA 160 controls the auxin response factor-class III peroxidase module and couples salicylic acid and redox signaling networks in the potato hypersensitive response to potato virus Y.

The New phytologist | 2026-Oct-17

This study reveals that microRNA 160 (miR160) acts as a critical regulatory node in potato (Solanum tuberosum) hypersensitive response against potato virus Y (PVY). By repressing miR160, the plant activates a StARF10/StARF17-StPRX28 signaling module that links salicylic acid, auxin, and redox networks to restrict viral infection. These findings highlight miR160 as a valuable functional genomics target for enhancing disease resistance and heat resilience without sacrificing tuber development.

Rhizobacterial biocontrol of potato late blight and genomic insights into disease suppression and growth promotion.

iScience | 2026-Oct-16

This study evaluates rhizobacterial strains, particularly Serratia rubidaea AV10 and EV23, for their capacity to control potato late blight (Phytophthora infestans) and promote plant growth. Genomic analysis of the bacteria identified biosynthetic clusters linked to biocontrol and growth traits, while treated potato plants exhibited altered expression of key defense- and auxin-related genes.
