| Outline of Final Research Achievements |
About 50% of the nitrogen (N)-fertilizer applied into cropping systems is not absorbed by plants, but lost to the environment as ammonia (NH3), nitrate (NO3-), and nitrous oxide (N2O), a greenhouse gas with a global warming potential of 300 times greater than that of CO2, raising agricultural production costs and contributing to pollution and climate changes. These N losses are caused by nitrification, the oxidation of NH3 to NO3-, catalyzed by the ammonia- and nitrite-oxidizing bacteria (AOB and NOB). To reduce nitrification and N2O emissions, we have developed seed compounds of novel nitrification inhibitors targeting hydroxylamine oxidoreductase, one of the two key enzymes of AOB, by utilizing the structure-based drug design method.
