Nitrous oxide reductase (nosZ) gene fragments differ between native and cultivated Michigan soils

Article Abstract:

Research shows that the native soil exhibit a less diverse denitrifying community than the cultivated soil as revealed by diversity indices, sequence identities, and the phylogenetic tree. The denitrification involves reduction of nitrous oxide to molecular nitrogen mediated by nitrous oxide reductase encoded by the nosZ gene.
