Biocontrol efficacy of the sboA and bacG mutants against BFB under greenhouse conditions. Blank: PBS buffer was used to immerse the germinated melon seeds, and a saline solution (0.9% NaCl) was used to spray the seedlings; Control: PBS buffer was used to immerse the germinated seeds, and the seedlings were sprayed with A. citrulli; 9407: the germinated seeds were soaked in a suspension of B. subtilis 9407 and the seedlings were sprayed with A. citrulli; sboA: the germinated seeds were soaked in the sboA mutant and the seedlings were sprayed with A. citrulli; bacG: the germinated seeds were soaked in the bacG mutant and the seedlings were sprayed with A. citrulli
