Fig. 5From: The involvement of extracellular ATP in regulating the stunted growth of Arabidopsis plants by repeated woundingEffect of the repeated application of ATP (1 mM) on the growth of WT and p2k1-3 mutant seedlings. a Leaf area. b Root length. c Fresh weight. d Dry weight. The first application of ATP was performed at 21th day of growth, indicated by the red line. Control: the WT seedlings without ATP treatment, and ATP: the WT seedlings repeatedly treated with ATP. The values represent means ± SD from twenty independent seedlings. For Fig. 5a, different letters on top of the bars indicate significant differences (P < 0 .05) among the different treatments at the same time. For Fig. 5b-d, the means denoted by the same letter did not significantly differ at P < 0.05 among the different treatmentBack to article page
