Figure 7. Root growth phenotype of Arabidopsis GbD14-OE plants.

Figure 7

(A) Root growth of the wild type (WT), L6, and L8 on MS medium with or without GR24 . A total of 3-day-old seedlings grown on MS medium were transferred to MS medium with or without GR24. They continued to grow for 5 or 10 days before being photographed and measured. A total of 30 seedlings were measured in each experiment. (B) Expression of GbD14 in WT and overexpression lines (L1-L11). (C and D) Comparison of primary root length (5-day seedlings) and lateral root density (10-day seedlings) among the WT, L6, and L8 on MS medium with or without GR24 (three μM). The experimental group without GR24 as Control. Experiments were performed three times with consistent results. Results are shown as mean ± SE of three replicates. The single and double asterisks show the data of the overexpression lines treat with GR24 significantly differed from that without GR24 by Student’s t-test at P ≤ 0.05 and P ≤ 0.01, respectively.
