Analysis of the physiological indices in WT and transgenic lines (L2 and L8) under drought stress. Six-week-old seedlings were withheld water for 10 days to measure the value of RWC (A), water loss rate (B), proline content (C) and MDA (D). Error bars represent SD and values with different letters are significant at P < 0.05.
