This study characterizes the cytochrome P450 (CYP450) superfamily in Solanum tuberosum to identify enzymes involved in the metabolism of absorbed volatile organic compounds. The researchers identified specific CYP81D members as key candidates for the oxidative detoxification of VOCs, providing a genetic foundation for understanding plant-plant interactions and potential crop protection strategies.
This study investigates the role of exogenous melatonin in mitigating cadmium-induced oxidative stress in potato seedlings. Through transcriptomic and physiological analysis, the researchers identify key genes and metabolic pathways, such as carbon fixation and antioxidant defense, that contribute to improved cadmium tolerance and growth recovery in potatoes.
This study investigates the spatial heterogeneity of starch accumulation in tetraploid potato tubers by integrating transcriptomic and metabolomic data from high- and low-starch cultivars. The researchers identified key transcription factors and structural genes that regulate carbon partitioning, providing insights into the molecular mechanisms underlying starch biosynthesis and offering potential targets for potato breeding.
This study performed a genome-wide identification and characterization of nine annexin genes (StANN1–StANN9) in potato (Solanum tuberosum) to elucidate their roles in salt stress response. Integrated transcriptomic and WGCNA analyses highlighted key annexins, particularly StANN5 and StANN6, as major regulators in stress signaling and potential targets for breeding salt-tolerant potato varieties.
This study evaluated 73 Solanum tuberosum accessions for freezing tolerance and performed transcriptomic profiling on contrasting germplasm lines. The authors identified phenylpropanoid biosynthesis-related phenylalanine ammonia-lyase (PAL) genes as key candidate genes associated with the freezing stress response, providing valuable germplasm resources and molecular targets for breeding freezing-tolerant potato cultivars.
This study demonstrates that synthetic analogs of the potato systemin peptide can effectively enhance resistance against Potato Virus Y (PVY) in Solanum tuberosum. The findings suggest that these peptides serve as promising, eco-friendly bioregulators for protecting potato crops from both ordinary and recombinant viral strains.
This study investigated the effects of ultrasound-assisted enzymatic treatment and exogenous amino acids on the structural, antioxidant, and flavor properties of Maillard reaction products derived from potato protein hydrolysates. The results demonstrate that energy-divergent ultrasound combined with specific amino acids significantly enhanced antioxidant activity and low molecular weight peptide content while reducing bitterness and enhancing umami taste. Overall, the method provides a prospective approach for utilizing potato proteins to produce natural food flavorings with improved antioxidant profiles.
This study developed an attenuated Cucumber Mosaic Virus (CMV)-based vaccine vector capable of accommodating exogenous viral fragments, including sequences from Potato virus Y (PVY) and Potato virus X (PVX). The engineered construct demonstrated effective cross-protection against these targeted virulent viruses, presenting a potential strategy for managing viral pathogens affecting potatoes and other crops.
This study explores the use of potato by-product-derived single-cell protein (SCP) as a functional ingredient to enhance the nutritional and bioactive properties of watermelon jelly. It highlights the potential for valorizing potato processing waste in food science applications, specifically focusing on antioxidant and enzyme inhibitory activities.
This study utilized dual RNA-seq to analyze the transcriptomic responses of potato (Solanum tuberosum) leaves during Botrytis cinerea infection. The authors identified key potato genes involved in defense signaling, hormone pathways, and specialized terpene biosynthesis (germacrene B and α-farnesene). A comparative analysis with tomato revealed conserved defense responses alongside species-specific differences in specialized metabolism and fungal virulence expression.
