Natural variation of the wheat root exudate metabolome and its influence on biological nitrification inhibition activity.

ABSTRACT: Excessive nitrogen use and low nitrogen use efficiency (NUE) in current agroecosystems are disrupting the global nitrogen cycle. Chemical inhibitors offer only temporary relief, while plant-derived biological nitrification inhibitors (BNIs) remain safer but underexplored. Identifying biological nitrification inhibition (BNI) traits in nitrogen-demanding crops like wheat is key to improving sustainability. In this study, a combined GC- and LC-MS platform was used to determine the metabolome of the root exudates of 44 diverse wheat genotypes originating from India and Austria. With more than 6000 metabolic features, a pronounced genotype-specific variation, a clear geographic pattern and an unexpected complexity of the root exudate metabolome were observed. A novel high-throughput assay util
