摘要

Abstract Paddy fields are hotspots of microbial denitrification, which is typically linked to the oxidation of electron donors such as methane (CH 4 ) under anoxic and hypoxic conditions. While several anaerobic methanotrophs can facilitate denitrification intracellularly, whether and how aerobic CH 4 oxidation couples with denitrification in hypoxic paddy fields remains virtually unknown. Here we combine a ~3300 km field study across main rice-producing areas of China and 13 CH 4 -DNA-stable isotope probing (SIP) experiments to investigate the role of soil aerobic CH 4 oxidation in supporting denitrification. Our results reveal positive relationships between CH 4 oxidation and denitrification activities and genes across various climatic regions. Microcosm experiments confirm that CH 4 and methanotroph addition promote gene expression involved in denitrification and increase nitrous oxide emissions. Moreover, 13 CH 4 -DNA-SIP analyses identify over 70 phylotypes harboring genes associated with denitrification and assimilating 13 C, which are mostly belonged to Rubrivivax , Magnetospirillum , and Bradyrhizobium . Combined analyses of 13 C-metagenome-assembled genomes and 13 C-metabolomics highlight the importance of intermediates such as acetate, propionate and lactate, released during aerobic CH 4 oxidation, for the coupling of CH 4 oxidation with denitrification. Our work identifies key microbial taxa and pathways driving coupled aerobic CH 4 oxidation and denitrification, with important implications for nitrogen management and greenhouse gas regulation in agroecosystems.
