Endophyte effects on dry weights.

<p>(a, b) Boxplots illustrating variability of dry weight in E-treated and control (C) <i>Arabidopsis</i> plants 14 (a) and 21 (b) DAI. The reference hatched line represents the median of controls. Differences were considered significant at a probability level of *: p<0.05; **: <0.01; and ***: <0.001. (c, d) Pooled data for controls (C) and plants treated with all (E), stem (stem-E) and root (root-E) endophytes and 14 (a) and 21 (b) DAI.
