Microorganisms in the phyllosphere of Norway spruce controlling nitrous oxide dynamics.

ABSTRACT: Current climate change assessments and greenhouse gas flux models often lack information on the microbiological processes that consume atmospheric nitrous oxide (N₂O), a potent greenhouse gas. There is limited understanding of phyllospheric microorganisms controlling N₂O exchange. In this study, we determined the microbial potential for N₂O consumption in aboveground vegetation in boreal forests. For this, we collected shoot samples from upland spruce forests in Finland and used a novel targeted metagenomics approach with a hybridization capture of gene-specific probes. Most of the samples contained nosZ genes, encoding the N₂O reductase. Phylogenetic placement showed a significantly higher relative abundance (P < .01) of nos
