(A) Cladogram showing phylogenetic relationships between 88 rhizosphere soil Pseudomonas spp. as well as OTU7. Leaf labels indicate representative sequence IDs. The inner rings indicates the species-level taxonomy, and the outer ring represents the soil from which the strain was isolated. (B) The percentage of Pseudomonas isolates with FOC inhibition ability or with B. amyloliquefaciens W19 inhibition ability in our dual challenge assays, or with biofilm-enhancing effects in co-culture biofilm assays with W19 (t-test, mean SD, n = 3; *P < 0.05, **P < 0.01). OF+W19 = Bio-organic fertilizer containing B. amyloliquefaciens W19, OF = Organic fertilizer
