From: Lignin metabolism involves Botrytis cinerea BcGs1- induced defense response in tomato
H2O2 accumulation and the activity of PAL and POD in BcGs1-induced tomato leaves. a H2O2 accumulation at 2 h, 4 h, 6 h after BcGs1 induction; b Quantitative determination of H2O2 content. BcGs1-infiltrated areas were stained brown compared with the buffer control. The asterisks* and ** indicate significance of p = 0.05 and p = 0.01, respectively. c Kinetics of PAL and POD activity after BcGs1 treatment of the leaves. The activities were measured 0–120 h after BcGs1 treatment. The values are the mean ± SD of triplicate samples
