Figure 8. Drought and salt stress-induced changes in Pro contents.

Figure 8

Effect of drought and salt stress on contents of Pro was shown in panel A. The expression levels of genes encoding Pro synthetase (P5CS1) and dehydrogenase (ProDH) 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. * P≤0.05, ** P≤0.01.
