Figure 1. Effects of TIS108 on Arabidopsis. (A) Structure of SL biosynthesis inhibitors, TIS13 (left) and TIS108 (right). (B) The number of branches in TIS108-treated Arabidopsis. The data are mean ± SE of 8 to 14 samples. (C–E) Arabidopsis treated with 0 µM TIS108 (C), 3 µM TIS108 (D) and 3 µM TIS108 and 5 µM GR24 (E). Scale bar indicates 5 cm. (F–G) The length of root hairs in TIS108-treated Arabidopsis. Y-axis as: length of root hairs. The data are mean ± SD of 4 to 7 biological replicates. Note: * and ** means are statistically different from that of the control treatment, determined by t-tests (p < 0.05 and p < 0.01, respectively). GR:, 5 µM GR24.
