Abstract excerpt
N(2)O reductase activity in soybean nodules formed with Bradyrhizobium japonicum was evaluated from N(2)O uptake and conversion of (15)N-N(2)O into (15)N-N(2). Free-living cells of USDA110 showed N(2)O reductase activity, whereas a nosZ mutant did not. Complementation of the nosZ mutant with two cosmids containing the nosRZDFYLX genes of B. japonicum USDA110 restored the N(2)O reductase activity. When detached...
