抄録

Soybean plants host endosymbiotic dinitrogen (N₂)-fixing bacteria from the genus Bradyrhizobium. Under oxygen-limiting conditions, Bradyrhizobium diazoefficiens and Bradyrhizobium japonicum perform denitrification by sequentially reducing nitrate (NO₃^–) to nitrous oxide (N₂O) or N₂. The anaerobic reduction of NO₃^– to N₂O was previously shown to be lower in B. japonicum than in B. diazoefficiens due to impaired periplasmic nitrate reductase (Nap) activity in B. japonicum. We herein demonstrated that impaired Nap activity in B. japonicum was due to low Nap protein levels, which may be related to a decline in the production of FixP and FixO proteins by the cbb₃-type oxidase.
