Diversity and N₂O Production Potential of Fungi in an Oceanic Oxygen Minimum Zone.

ABSTRACT: Fungi in terrestrial environments are known to play a key role in carbon and nitrogen biogeochemistry and exhibit high diversity. In contrast, the diversity and function of fungi in the ocean has remained underexplored and largely neglected. In the eastern tropical North Pacific oxygen minimum zone, we examined the fungal diversity by sequencing the internal transcribed spacer region 2 (ITS2) and mining a metagenome dataset collected from the same region. Additionally, we coupled ¹⁵N-tracer experiments with a selective inhibition method to determine the potential contribution of marine fungi to nitrous oxide (N₂O) production. Fungal communities evaluated by ITS2 sequencing were dominated by the phyla Basidiomycota and Ascomycota at most depths. However,
