Effect of the repeated wounding on the growth of the seedlings with the IBU application or MYC2 mutation. a Leaf area. b Root length. c Fresh weight. d Dry weight. The first wounding, the first IBU application, or first wounding plus IBU application were performed at 21th day of growth, indicated by the red line. WT-control: the un-wounded WT seedlings, WT-wounded: the wounded WT seedlings, WT-wounded plus IBU: the wounded WT seedlings treated with IBU, myc2-2-wounded: the wounded myc2-2 mutant seedlings. The values represent means ± SD from sixteen independent seedlings. For Fig. 6a, different letters on top of the bars indicate significant differences (P < 0 .05) among the different treatments at the same time. For Fig. 6b-d, the means denoted by the same letter did not significantly differ at P < 0.05 among the different treatment
