Detection of plant growth-promoting characteristics of Rahnella victoriana JZ-GX1. (A) Siderophore production, (B) inorganic phosphorus dissolution, (C) organophosphorus dissolution, (D) acetoin production, (E) nitrogen fixation, (F) potassium solubilization, (G) IAA and ACC deaminase production, and (H) detection of key gene related to PGP traits in JZ-GX1 by PCR amplification (lane M, DNA marker; 1, acdS; 2, gadB; 3, gadD; 4, gabT; 5, speA; 6, speD; 7, G1pase; 8, pstA; 9, pstC; 10, nirB). One-way ANOVA was performed, and Duncan’s post-hoc test was applied. Different letters indicate statistically significant differences (p < 0.01) among treatments (n = 3).
