Summary, etc. A bioluminescence assay using recombinant Nitrosomonas europaea was adopted to detect and quantify natural nitrification inhibitors in plant–soil systems. The recombinant strain of N. europaea produces a distinct two-peak luminescence due to the expression of luxAB genes, introduced from Vibrio harveyi, during nitrification. The bioluminescence produced in this assay is highly correlated with NO-2 production (r2 = 0.94). Using the assay, we were able to detect significant amounts of a nitrification inhibitor produced by the roots of Brachiaria humidicola (Rendle) Schweick. We propose that the inhibitory activity produced/released from plants be termed ‘biological nitrification inhibition’ (BNI) to distinguish it from industrially produced inhibitors. The amount of BNI activity produced by roots was expressed in units defined in terms of the action of a standard inhibitor allylthiourea (AT). The inhibitory effect from 0.22 μM AT in an assay containing 18.9 mM of NH+4 is defined as one AT unit of activity. A substantial amount of BNI activity was released from the roots of B. humidicola (15–25 AT unit g–1 root dry wt day–1). The BNI activity released was a function of the growth stage and N content of the plant. Shoot N levels were positively correlated with the release of BNI activity from roots (r2 = 0.76). The inhibitor/s released from B. humidicola roots suppressed soil nitrification. Additions of 20 units of BNI per gram of soil completely inhibited NO-3 formation in a 55-day study and remained functionally stable in the soil for 50 days. Both the ammonia monooxygenase and the hydroxylaminooxidoreductase enzymatic pathways in Nitrosomonas were effectively blocked by the BNI activity released from B. humidicola roots. The proposed bioluminescence assay can be used to characterize and determine the BNI activity of plant roots, thus it could become a powerful tool in genetically exploiting the BNI trait in crops and pastures.
