In-depth characterization of denitrifier communities across different soil ecosystems in the tundra.

ABSTRACT:

Background

In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N₂O). However, the microorganisms involved in the cycling of N₂O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N₂O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra.

Results

We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then searched for MAGs harbouring genes involved in denitrification, an
