Abstract

• Conventional agriculture relies heavily on nitrogen (N) fertilizers to increase short-term crop yields.
• Microbial nitrification and denitrification drive N losses from soil systems.
• Denitrification produces N O, a potent green house gas (GHG).
• Biological denitrification inhibition (BDI) traits are present in the ancestor of modern maize, teosinte.
• Reintroduction of BDI traits into modern maize can reduce GHG production and increase nutrient use efficiency (NUE) as it minimizes soil N losses from denitrification.
• Monitoring N O emissions from BDI-introgressed maize lines can asses GHG reduction and potential NUE gains.
