Long-Read Amplicon Sequencing of Nitric Oxide Dismutase (nod) Genes Reveal Diverse Oxygenic Denitrifiers in Agricultural Soils and Lake Sediments

Microorganisms play an essential role in nitrogen cycling and greenhouse gas emissions in soils and sediments. The recently discovered oxygenic denitrifiers are proposed to reduce nitrate and nitrite via nitric oxide dismutation directly to N 2 and O 2 . So far, the ecological role of these microbes is not well understood. The only available tool for a targeted study of oxygenic denitrifiers is their respective maker gene, nitric oxide dismutase...
