图6 过表达OsMPK17蛋白质水稻发芽期耐旱性鉴定 A: 水稻种子萌发照片。上部: 对照(水); 下部: 干旱胁迫(20% PEG-6000)。B: 水稻种子萌发的根长和芽长柱状图。WT为野生型; A202、A204、A210和A212为4个转基因株系。试验重复3次, 计算平均值和方差。*表示在0.05水平差异显著; **表示在0.01水平差异显著。

Fig. 6 Characterization of the germination trait of rice seeds with over-expressed OsMPK17 protein under drought stress A: Photographs for seeds at germination. Upper panel: control (H2O); Lower panel: drought stress (20% PEG-6000) treatment. B: Bar graphs of root and shoot lengths for seeds at germination. WT: wild type; A202, A204, A210, and A212 are transgenic lines. Experiments were carried out with three replicates; average and standard derivations were calculated. * Significant at P < 0.05. ** Significant at P < 0.01.
