Fig. 6From: Melatonin increases growth and salt tolerance of Limonium bicolor by improving photosynthetic and antioxidant capacityEffects of melatonin (5 μM) on MAPK gene expression of L. bicolor leaves in six-week-old seedlings subjected to 300 mM NaCl for 0, 12, 24, 48 and 72 h. Values are mean ± standard deviation of three biological replicates. Bars labeled with different letters are significantly different at P < 0.05 according to Duncan’s multiple range tests.
