摘要： The interactions between plants and microbes are essential for enhancing crop productivity. However, the mechanisms underlying host-specific microbiome migration and functional assembly remain poorly understood. In this study, microbiome migration from soil to leaves in rice (Oryza sativa) and maize (Zea mays) was analyzed through 16S rRNA sequencing and phenotypic assessments. When we used the same soil microbiome source to grow rice and maize, microbiota and functional traits were specifically enriched by maize in its phyllosphere and rhizosphere. This indicated that plants can selectively assemble microbiomes from a shared microbiota source. Therefore, 22 strains were isolated from the phyllospheres of rice and maize and used to construct a synthetic microbial community (SynCom). When the soil for rice and maize growth was inoculated with the SynCom, strains belonging to Bacillus were enriched in the maize phyllosphere compared to the rice phyllosphere. Additionally, a strain belonging to Rhizobium was enriched in the maize rhizosphere compared to the rice rhizosphere. These results suggest that plant species influence the migration of microbiota within their respective compartments. Compared with mock inoculation, SynCom inoculation significantly enhanced plant growth. When we compared the microbiomes, strains belonging to Achromobacter, which were assembled by both rice and maize, played a role in enhancing plant growth. Our findings underscore the importance of microbial migration dynamics and functional assembly in leveraging plant-microbe interactions for sustainable agriculture.
