Drought and salt stress-induced changes in Pro contents.

<p>Effect of drought and salt stress on contents of Pro was shown in panel A. The expression levels of genes encoding Pro synthetase (<i>P5CS1</i>) and dehydrogenase (<i>ProDH</i>) under stress were shown in panel B and C, respectively. Data are mean±SE with three replicates. Asterisks represent statistically significant differences between wild-type and transgenic lines. * <i>P</i>≤0.05, ** <i>P</i>≤0.01.
