Warming shapes < em > nirS- < /em > and < em > nosZ < /em > -type denitrifier communities and stimulates N < sub > 2 < /sub > O emission in acidic paddy soil

This study demonstrated high temperature-induced N2O emission from submerged paddy soils, mainly via stimulating denitrification. Further, we speculate that key functional denitrifiers drive N2O emission. This study showed that denitrifiers were more sensitive to temperature rise than nitrifiers, and the temperature sensitivity differed among denitrifier communities. N2O-consuming denitrifiers (nosZ-containing denitrifiers) were more sensitive at a higher temperature range than N2O-producing denitrifiers (nirS-containing denitrifiers). This study's findings help predict N2O fluxes under different degrees of warming and develop strategies to mitigate N2O emissions from paddy fields based on microbial community regulation.PMID:33837014 | DOI:10.1128/AEM.02965-20
