Organic molecules exuded into water column by marine organisms represent a significant portion of dissolved organic matter (DOM) that modulates biochemical interactions. Secreted allelochemicals have been suggested to be involved in regulation pathogen abundance seagrass meadows, however, exometabolome has remained unstudied. We aimed identify exometabolites, within and outside explore their potential involvement suppression under varying environmental conditions. collected seawater (SW) samples from eelgrass (Zostera marina)-vegetated (V) non-vegetated (NV) areas across 5 locations spanning 270 km coastline along the German Baltic Sea. Comparative LC-MS/MS-based untargeted computational metabolomics combined with statistical analyses machine learning tools were employed pinpoint (exo)metabolomic signatures leaves. Simultaneously, we measured abiotic parameters three common pathogenic taxa seawater, investigated spatiotemporal variations. Here show correlation biomass reduction effect increasing temperature, eutrophication anthropogenic influences. Exometabolomics studies revealed exudates contributed significantly overall DOM at molecular level, while SW overlying meadows contained many chemical features unique leaf metabolome. identified four flavone aglycones as key biomarkers distinguishing SW-V SW-NV samples. Their drastically increased concentrations correlated lowest biomass, suggesting role regulation. These analytical microbiological approaches indicate flavones are defensive released upon stress serve bioindicators eelgrass' sanitation effect.
