Fig. 4 in Melatonin mitigates UV-B stress via regulating oxidative stress response, cellular redox and alternative electron sinks in Arabidopsis thaliana

Fig. 4. Activities of APX, GR, POX (90 and 180 min) and expressions of APX1 and GR1 genes (at 90 min) of UV-B treated A. thaliana plants with or without 10 μM melatonin supplement. Experiments were repeated two times, and each data point was the mean of three replicates (n = 6). Significant differences (P <0.05) were marked with different letters (a–d) in the charts.
