Effect of the repeated wounding on the growth of WT and p2k1-3 mutant seedlings. a Leaf area. b Root length. c Fresh weight. d Dry weight. e Photograph of plant growth of WT and p2k1-3 mutant seedlings was taken at 10th day after the first wounding. The first wounding was performed at 21th day of growth, indicated by the red line. WT-control: the un-wounded WT seedlings, WT-wounded: the wounded WT seedlings, p2k1-3-control: the un-wounded p2k1-3 mutant seedlings, and p2k1-3-wounded: the wounded p2k1-3 mutant seedlings. The values represent means ± SD from twenty independent seedlings. For Fig. 4a, different letters on top of the bars indicate significant differences (P < 0 .05) among the different treatments at the same time. For Fig. 4b-d, the means denoted by the same letter did not significantly differ at P < 0.05 among the different treatment
