Effect of B. phytofirmans PsJN on A. thaliana proline accumulation. Graphic representation of proline levels in A. thaliana plants treated with or without B. phytofirmans PsJN, and transplanted at 11 DAS to half strength MS media with (B) or without (A) addition of 150 mM NaCl/15 mM CaCl2. Proline was extracted 2, 24, and 48 h after transplantation. Data are means ± 1 SE of at least three biological replicates. Asterisks indicate significant differences amongst treatments (Two-way ANOVA, p < 0.05; Bonferroni test, ∗∗P < 0.05).
