This study examines the physiological and molecular responses of potato (*Solanum tuberosum* cv. 'Atlantic') to alkaline salt stress induced by NaHCO3. The findings reveal that potato adapts to stress through coordinated mechanisms involving enhanced antioxidant defenses, increased root lignin accumulation, and altered expression of genes in the phenylpropanoid and hormone (ABA, GA, BR) signaling pathways. These results provide valuable theoretical insights for breeding salt- and alkali-tolerant potato cultivars.
This randomized, double-blind, placebo-controlled clinical trial evaluated the gastrointestinal and prebiotic effects of Solnul®, a resistant starch derived from potato. The findings demonstrated that daily consumption of 3.5 g of resistant potato starch significantly increased beneficial Bifidobacterium abundance and normalized stool form without causing adverse effects. This study confirms the gut health and bifidogenic benefits of potato-derived resistant starch in healthy adults.
This study functionally characterizes the potato transcription factor StWRKY70 in conferring resistance against early blight caused by Alternaria solani. StWRKY70 directly binds to and activates the promoter of StAOS, a key jasmonic acid (JA) biosynthesis gene, thereby boosting JA signaling and antioxidant enzyme activity. These findings highlight the StWRKY70-StAOS regulatory module as a promising genetic target for breeding early blight-resistant potato cultivars.
This study evaluated the causal agents of potato early dying (PED) in Colorado's San Luis Valley using molecular diagnostics and pathogenicity assays. Verticillium dahliae was identified as the primary pathogen responsible for the full PED syndrome, whereas Colletotrichum coccodes caused minimal disease alone and did not enhance disease severity in co-inoculations. These findings highlight the necessity of targeting V. dahliae to manage PED in potato production effectively.
