Figure 1.

The effect of inoculation with either wild type FZB42 or the epsC mutant on the performance of A. thaliana seedlings. Appearance of the plants. Scale bar, 2 cm (A), seedling survival rate under drought stress (B), shoot fresh weight (C), shoot dry weight (D), root dry weight (E), primary root length (F), lateral root number (G), total lateral root length (H). Values in (B) through (H) are shown as means, with the whiskers representing the standard error (SE, n = 18). Different letters above each column indicate statistically significant (p < 0.05) differences in mean performance.
