Fig. 6 in Melatonin mitigates UV-B stress via regulating oxidative stress response, cellular redox and alternative electron sinks in Arabidopsis thaliana

Fig. 6. Expressions of glutathione biosynthesis (GSH1 and GSH2) and degradation (OXP1 and GGT1) related genes of UV-B treated (90 min) 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.
