Summary statement We performed metagenomic sequencing to analyze the microbial composition and functional profiles of the rhizosphere microbiome in the soybean cultivar Dongsheng 7 grown in black soil at Meilisi, Northeast China. Furthermore, we constructed a microbial genome database and isolated endophytic bacteria from root nodules, providing support for further research and potential applications of the soybean‐rhizobia symbiotic nitrogen fixation system.
