Biomass assay in overexpression <i>LOS5</i> transgenic maize.

<p>Seedlings 21-d-old WT and transgenic maize (lines M-6 and M-8) were exposed to severe drought stress (D2) by withholding water for 5 d and then restoring it for 5 d. The data points are the mean of two independent biological experiments, and each experiment comprised ten samples. Error bars denote the standard deviation values, and asterisks indicate a significant difference (*<i>P</i><0.05) compared with the corresponding controls.
