图3 干旱胁迫下转化株系的植株生长特征 A: 干旱胁迫下TaPYR1转化株系植株生长情况; B: 干旱胁迫下TaPYR1转化株系干质量。WT, 野生型; Sen 1和Sen 2, 正义表达TaPYR1株系; Anti 1和Anti 2, 反义表达TaPYR1株系。误差线表示标准差, 符号*表示相对于WT的差异显著(P < 0.05)。

Fig. 3 Growth characteristics of the transgenic plants under drought stress A: Plant growth characteristics of transgenic lines overexpressing TaPYR1 under drought stress; B: Plant biomass of transgenic lines overexpressing TaPYR1 under drought stress. WT, wild type; Sen 1 and Sen 2, lines overexpressing TaPYR1; Anti 1 and Anti 2, lines with TaPYR1 knockdown expression. Error bars indicate SE and symbol * represents significant difference relative to WT (P < 0.05).
