Research Abstract

This research aimed to construct the databases of nitrous oxide(N_2O)-producing fungi, and to reevaluate the ecological role of soil fungi for the nitrogen cycle(nitrification and denitrification). The activity of N_2O production was observed in the extensive phylogenetic groups of soil fungi, and the intensity of N2O producing activity was divided by phylogenetic groups. These results offer the foundational knowledge towards the sustainable agricultural practices for controlling the N_2O emission from field soil.
