Synthetic microbial communities (SynComs) could potentially enhance some functions of the plant microbiome and emerge as a promising inoculant for improving crop performance. Here, we characterized collection bacteria, previously isolated from wheat rhizosphere, their antifungal activity against soilborne fungal pathogens. Ten SynComs with different compositions 14 bacterial strains were created. Seven protected Rhizoctonia solani AG8 infection, although not more effective than single in reducing root rot disease. Further, mechanisms interaction tested bacteria each other plants explored. We found that nine impacted growth Arabidopsis. Nine four significantly inhibited by producing volatiles. The cell-free supernatants six AG8. Together, this study provided potential resilience creating SynComs.
