Fig. 1 in Melatonin mitigates UV-B stress via regulating oxidative stress response, cellular redox and alternative electron sinks in Arabidopsis thaliana

Fig. 1. TBARS and Fv/Fm (maximum efficiency of PSII) values of UV-B treated (90 and 180 min) A. thaliana plants with or without melatonin supplement. C90 and C180: control groups, UV90 and UV180: plants treated with UV-B for 90 or 180 min. M90 and M180: melatonin (10 μM), UVM90 and UVM180: UV-B + melatonin treated plants. Note that Y-axis of Fv/Fm starts from 0.5 for better reflection of differences between treatment groups.
