Camalexin is important for PGP effect of Pseudomonas sp. CH267. (A) Col-0 and mutants in camalexin synthesis were grown for 2 wk in presence of 10 µM MgCl2 as mock, Pseudomonas sp. CH267, 10 µM camalexin (cam), and both CH267 and camalexin. The FW of the whole plants was determined. Data are presented as means and SE from at least 20 plants grown on 4 independent plates. Asterisks indicate significant differences to mock treatment at P < 0.05 (Student’s t test). Two-way ANOVA revealed that FW of the plants depends on genotype (P = 1.3 × 10−10), treatment (P = 0.0065), and genotype:treatment (P = 1.4 × 10−12). (B) Col-0 and mutants in camalexin synthesis were grown for 2 wk in presence of 10 µM MgCl2 as mock, Pseudomonas sp. CH267, and CH267 supplemented with camalexin (cam) at 3 different concentrations: 3, 10, and 25 µM. The FW of the whole plants was measured. Data are presented as means and SE from at least 20 plants grown on 4 independent plates. Asterisks indicate significant differences to mock treatment at P < 0.05 (Student’s t test). Two-way ANOVA revealed that FW of the plants depends on genotype (P = 5.1 × 10−5) and genotype:treatment (P = 6.4 × 10−5).
