图1 单侧强弱蓝光差异诱导拟南芥野生型和突变体下胚轴向光弯曲 A和B: 拟南芥野生型和突变体rpt2-2、phot1、phot1 rpt2-2、phot2 rpt2-2和phot1 phot2响应单侧蓝光(A: 100 μmol m-2 s-1; B: 0.01 μmol m-2 s-1)的下胚轴向光弯曲表型。C和D: 蓝光(C: 100 μmol m-2 s-1; D: 0.01 μmol m-2 s-1)诱导下胚轴向光弯曲度测量统计结果。图中每个数据分别来自3次独立重复试验, 大约15~20颗苗的平均值±标准误。

Fig. 1 Hypocotyl phototropic curvature in wild type (WT) and mutant seedlings in response to unilateral blue light at the indicated fluence rates A and B: phototropic phenotype of WT, rpt2-2, phot1, phot1 rpt2-2, phot2 rpt2-2, and phot1 phot2 to 100 μmol m-2 s-1 (A) or 0.01 μmol m-2 s-1 (B) unilateral blue light for 12 h. C and D: bar graph of the phototropic curvature of seedlings from A (C) or B (D). Each column represents an average of three experiments (15-20 measurements each) ±SD.
