Table 3 Banana growth factors, ethylene concentrations, and indole-3-acetic acid (IAA) concentrations of banana of the control treatments (CK) and treatments with artificial inoculation of endophytes Kosakonia sp. S1 (S1), Enterobacter sp. E5 (E5), Klebsiella sp. Kb (Kb), and the engineered strains of E5, S1, and Kb (designated as E5P, S1P, and KbP, respectively) by expressing deaminase on the bacterial cells
