Simplification of synthetic bacterial community I and disease control effects. a SCIII was constructed by mixing Stenotrophomonas sp., Rhizobium sp., Advenella sp., and Ochrobactrum sp. that survived joint selection by the host plant and F. oxysporum. The bar graph shows the abundance of the four bacterial strains in roots. b Root rot disease incidence in plants inoculated with different bacterial communities for 15 days. SCI, synthetic community I; SCII, synthetic community II; SCIII, four-species simple community. c Colony radii of F. oxysporum treated with different bacteria after 6 days of growth (n = 3). d Root rot incidence of Astragalus inoculated with mixed bacteria at different ratios. Asterisks indicate significant differences (Tukey test, P < 0.01). 10:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 10:10:1:1; 100:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 100:100:1:1; 600:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 600:200:10:1
