Abstract Background The assembly of the rhizomicrobiome, i.e., microbiome in soil adhering to root, is influenced by conditions. Here, we investigated core rhizomicrobiome a wild plant species transplanted an identical type with small differences chemical factors and impact these chemistry on after long-term cultivation. We sampled three natural reserve populations rice (i.e., situ) situ grown ex for more than 40 years determine rhizomicrobiome. Results Generalized joint attribute modeling (GJAM) identified total 44 amplicon sequence variants (ASVs) composing including 35 bacterial ASVs belonging phyla Actinobacteria, Chloroflexi, Firmicutes, Nitrospirae 9 fungal Ascomycota, Basidiomycota, Rozellomycota. Nine genera Haliangium , Anaeromyxobacter Bradyrhizobium Bacillus were abundant rhizosphere rice. main ecological functions nitrogen fixation, manganese oxidation, aerobic chemoheterotrophy, iron respiration, suggesting roles improving nutrient resource acquisition growth. function community was significantly ( p < 0.05) shaped electrical conductivity, nitrogen, available phosphorus present roots. Conclusion discovered that manganese, iron, carbon are potential Oryza rufipogon . Our findings suggest further utilization should consider effects properties abundances different genera.
