This study evaluates the use of potato peels as a carbon substrate for producing hydrolytic enzymes from a Bacillus species. The resulting enzyme mixture was successfully used to saccharify pretreated potato peel waste into glucose, which was then fermented to produce ethanol.
This study investigates how foliar infection of potato with Phytophthora infestans (late blight) affects the rhizosphere and soil bacterial communities of two cultivars with differing sensitivity. The researchers observed cultivar-specific shifts in the microbiome and isolated bacterial strains with biocontrol potential against the pathogen. The findings suggest that resistant potato cultivars may harbor specific microbiota that contribute to pathogen inhibition.
This study evaluates the performance of different ITS markers (ITS1, ITS2, and full-length ITS) for profiling fungal and oomycete communities in potato leaf and root tissues. The findings show that marker choice significantly influences observed community composition, with ITS2 performing better for leaves and full-length ITS for roots. The research suggests combining complementary markers for a more accurate representation of the potato microbiome.
This study utilizes untargeted metabolomics to analyze metabolic changes in potato seed tubers of four cultivars during storage at different temperatures. The researchers identified cultivar-specific metabolic profiles and observed significant shifts in primary and secondary metabolites, such as reducing sugars and glycoalkaloids, associated with storage duration and temperature. These findings contribute to a better understanding of the metabolic dynamics and physiological aging of potato tubers.
This review summarizes the low-temperature response and regulatory mechanisms of major crops in northern China, specifically including potato. It focuses on the key genes and adaptive strategies involved in cold tolerance, providing a theoretical basis for breeding cold-tolerant potato varieties.
This review paper discusses the molecular mechanisms of self-incompatibility in diploid potatoes (Solanum tuberosum), focusing on key genes like the S-locus inhibitor. It outlines emerging technologies such as genome editing and haploid induction to overcome self-incompatibility and accelerate diploid hybrid breeding.
This study presents an optimized and validated HPLC-DAD method for quantifying steroidal glycoalkaloids (α-solanine and α-chaconine) in potato tubers. The method was applied to potato breeding lines to assess genotype-dependent variations, providing a sustainable analytical tool for food safety monitoring and potato breeding programs.
This study evaluates the pathogenicity of twelve fungal isolates associated with dry rot on cold-stored potato tubers in Korea. The researchers identified various Fusarium species and Clonostachys rosea as causal agents of rot under low-temperature conditions. These findings highlight the need to consider both major and opportunistic fungal pathogens when managing postharvest potato dry rot.
This study investigates the use of wild potato volatiles to deter oviposition by the potato tuber moth (Phthorimaea operculella), a major potato pest. By comparing wild and cultivated potato varieties, the researchers identified specific volatile compounds, such as benzaldehyde and γ-terpinene, that repel gravid moths and deter egg-laying. These findings highlight the potential of wild potato genetic resources for developing pest-resistant varieties and integrated pest management strategies.
This study characterizes how the effector AVRcap1b from the potato late blight pathogen Phytophthora infestans suppresses host immunity. The researchers show that AVRcap1b interacts with the host protein TOL9a and the helper NLR NRC2 to inhibit immune signaling. These findings reveal a novel mechanism of pathogen-mediated immune suppression, which is highly relevant to engineering late blight resistance in potatoes.
