title: Nitrate-dependent N₂O emission from intact soybean nodules via denitrification by Bradyrhizobium japonicum bacteroids.
abstract: In the presence of nitrate, N₂O emission increased markedly from soybean roots inoculated with nosZ mutant of Bradyrhizobium japonicum, but not from soybean roots inoculated with a napA nosZ double mutant, indicating that B. japonicum bacteroids in soybean nodules are able to convert the exogenously supplied nitrate into N₂O via a denitrification pathway.
