Crop domestication has revolutionized food production but increased agriculture's reliance on fertilizers and pesticides. We investigate differences in the rhizosphere microbiome functions of wild and domesticated rice, focusing on nitrogen (N) cycling genes. Shotgun metagenomics and real-time PCR reveal a higher abundance of N-fixing genes in the wild rice rhizosphere microbiomes. Validation through transplanting rhizosphere microbiome suspensions shows the highest nitrogenase activity in soils with wild rice suspensions, regardless of planted rice type. Domesticated rice, however, exhibits an increased number of genes associated with nitrous oxide (N
