图4 P2SA2调节强蓝光诱导胚轴向光弯曲生长 A: 100 µmol m -2 s -1 蓝光单侧处理12 h不同基因型拟南芥下胚轴向光弯曲表型; B: 不同基因型拟南芥下胚轴向光弯曲度统计。图中每个数据分别来自3次独立重复试验, 大约18~21颗苗的平均值±标准误。其中1: WT; 2: phot1 ; 3: phot1phot2 ; 4: phot1p2sa2 ;5: phot1 P2SA2-OX1 ; 6: phot1 P2SA2-OX2 。
Fig. 4 Hypocotyl phototropism of p2sa2 mutant in etiolated seedlings was recovered by P2SA2 A: typical seedling phototropic curvature in indicated lines at 100 µmol m -2 s -1 blue light for 12 hours; B: hypocotyl curvatures were measured in indicated lines. 1: WT; 2: phot1 ; 3: phot1phot2 ; 4: phot1p2sa2 ; 5: phot1 P2SA2-OX1 ; 6: phot1 P2SA2-OX2 . Values are the means ± SD n = 18-21.
