图3. 外源生长素能部分恢复拟南芥fab1b/c/d突变体的短根毛表型
(A)-(C) 外源添加DMSO (Mock)、10 nmol·L^-1 2,4-D或0.1 μmol·L^-1 NAA可部分恢复fab1b/c/d突变体根毛表型(Bar=0.5 mm); (D) 定量分析根毛长度; (E), (F) 生长素运输抑制剂TIBA (生长素输出抑制剂)和1-NOA (生长素输入抑制剂)处理后根毛表型(Bar=0.5 mm); (G) 定量分析根毛长度。* P<0.05; ** P<0.01; *** P<0.001 (Student’s t-test)

Figure 3. Exogenous auxin application partially rescued the root hair defect of Arabidopsis fab1b/c/d mutants
(A)-(C) Root hairs of fab1b/c/d treated with DMSO (Mock), 10 nmol·L^-1 2,4-D and 0.1 μmol·L^-1 NAA, respectively, the phenotype of root hairs was rescued partially (Bar=0.5 mm); (D) Quantification of root hair length; (E), (F) Col-0 and fab1b/c/d seedlings were transferred to plates containing TIBA (auxin efflux inhibitors) and 1-NOA (auxin influx inhibitor) (Bar=0.5 mm); (G) Quantitative analysis of root hair length. * P<0.05; ** P<0.01; *** P<0.001 (Student’s t-test)
