Figure 1. Melatonin production in purified Arabidopsis chloroplasts and the effect of melatonin on their integrity.

Figure 1

(a) Different concentrations of N-acetylserotonin were added to purified Arabidopsis chloroplasts at 4 °C for 6 h. Melatonin concentration was quantified using HPLC. (b) The envelope integrity of chloroplasts with/without N-acetylserotonin (10 μmol/L) and melatonin (10 μmol/L) treatment at different time points. Asterisks (*) indicate significant differences from the control (*P < 0.05; **P < 0.01).
