Effect of plant species and soil depth on N2O reducers in a coastal wetland

Nitrous oxide (N2O) reducers are the only known sink for N2O and might be pivotal contributors to N2O mitigation in terrestrial and water ecosystems. However, the niche preference of nosZ I and nosZ II carrying microorganisms, two divergent clades of N2O reducers in coastal wetlands are not yet well documented. In this project, we investigated the abundance, community structure and co-occurrence network of nosZ I and nosZ II carrying microorganisms and their driving factors in a subtropical estuarine wetland with five plant species and a bare tidal flat at three depths. This study would advance our understanding of environmental adaptation and niche preference of nosZ I and nosZ II carrying microorganisms in coastal wetlands.
