Endophytes Enhance Rice Inorganic Nitrogen Use Efficiency and Mitigate Nitrogen Loss Via Dissimilatory Nitrate Reduction To Ammonium in Paddy Soils.

ABSTRACT: Rice cultivation involves the large amounts of fertilizers application, but nitrogen (N) use efficiency remains low. Endophytes are considered key microorganisms that regulate nitrogen utilization and gaseous nitrogen loss in rice paddy ecosystems. However, systematic studies on the effectiveness and underlying mechanisms of endophytes in nitrogen utilization by crops within paddy fields are still scarce. This study employed microcosmic experiments to investigate the effects of endophytes on gaseous nitrogen loss from paddy soil and inorganic nitrogen utilization in rice plants. Results demonstrated that colonization of endophytes increased the efficiency of inorganic N use by approximately twofold. The simultaneous addition of rice roots colonized with endophytes to the soil resulted in a
