Effects of stress on the relative rate of growth of WT and transgenic plants.

<p>Histograms showing a comparison in the rate of growth between WT and <i>TaLEA</i>-transformed poplars. A: Control condition; B: 200 mM NaCl treatment for 6 d; C: Withholding water for 7 d. At least five plants from each line were used for biological repeats in each experiment. Values are means ± S.D. and the level of significance was set at <i>P</i> < 0.05. The stars above the bars indicate significant differences (<i>P</i> < 0.05) between the transgenic lines compared with WT.
