MetabolomicsMulti-omics insights into high-carotenoid hybrid potato lines: enhanced nutritional quality and metabolic regulation for food applications

Modern potato varieties often exhibit low carotenoid content, limiting their nutritional value and processing performance. This study employed a multi-omics approach (physicochemical analysis, metabolomics, mineral profiling, transcriptomics, and microbiome sequencing) to investigate the molecula...

MetabolomicsFood Deprivation Enhances Disease Resistance: Underlying Mechanisms in Oysters Confronted with Pacific Oyster Mortality Syndrome

Variation in food availability can shape host susceptibility and pathogen virulence, thereby impacting disease outcomes. An ad libitum diet may enhance host physiology and immunity but it can also favor pathogen proliferation. Here, we investigated how food availability (ad libitum vs. starvation...

MetabolomicsThe metabolic response of marine copepods to environmental warming and ocean acidification in the absence of food
Marine copepods are central to the productivity and biogeochemistry of marine ecosystems. Nevertheless, the direct and indirect effects of climate change on their metabolic functioning remain poorly understood. Here, we use metabolomics, the unbiased study of multiple low molecular weight organic me...
