Competition assays in wheat roots: A. baldaniorum 2449 WT strain, A. baldaniorum 2450 mutant strain, and competition assay seedling inoculated with 1.1 with both strains, as described in “Materials and Methods” section. Bar plots representing the mean and standard error of colony-forming units recovered per gram of wheat root from colonization assays. The data was obtained from three independent experiments. The mean of WT and the competition assay was compared with a Student’s t-test and was significantly different with a P-value = 0.0142 indicated with one asterisk.
