摘要	Nitrous oxide (N2O) 2 O) is a potent greenhouse gas (GHG) and an ozone-depleting substance. The presence of plants in an ecosystem can either increase or decrease N2O 2 O emissions, or play a negligible role in driving N2O 2 O emissions. Here, we conducted a meta-analysis comparing ecosystem N2O 2 O emissions from planted and unplanted systems to evaluate how plant presence influences N2O 2 O emissions and examined the mechanisms driving observed responses. Our results indicate that plant presence reduces N2O 2 O emissions while it increases dinitrogen (N2) 2 ) emissions from ecosystems through decreases in soil nitrate concentration as well as increases in complete denitrification and mineral N immobilization. The response of N2O 2 O emissions to plant presence was universal across major terrestrial ecosystems - including forests, grassland and cropland - and it did not vary with N fertilization. Further, in light of the potential mechanisms of N2O 2 O formation in plant cells, we discussed how plant presence could enhance the emission of N2O 2 O from plants themselves. Improving our understanding of the mechanisms driving N2O 2 O emissions in response to plant presence could be beneficial for enhancing the robustness for predictions of our GHG sinks and sources and for developing strategies to minimize emissions at the ecosystem scale.
