Benzoxazinoids as candidate compounds for biological nitrification inhibition in wheat
values ranging from 8 to 47 μM. Root exudates of the BNI lines exhibited two-fold greater inhibition compared to their parent line, which correlated with higher concentrations of BXs in the root exudates. Overall, this study identifies BXs as strong candidate contributors to wheat BNI, suggesting that enhanced exudation of BXs can contribute to stronger inhibition of ammonia-oxidising bacteria and support more efficient and environmentally sustainable nitrogen use.
