Table 1: Tomato-associated rhizobacterial strains used and their main traits. Fen A: Fengycin A; Bac: Bacillomycin, IAA: Indole acetic acid; P.solubilization: Phosphate solubilization. All isolates were negative for hypersensitive reaction (HR) on tobacco leaves, and they were negative for the detection of Fengycin B, D and E. Positive reaction (+); Negative reaction (–); Production of siderophore was scored as non-detected (−), low (+), middle (++) and high (+++).
