Abstract In this study, biochemical and molecular responses of Peganum harmala L. (wild rue) were investigated following NaCl treatment (0, control-, 150- and 300 mmol L-1) under growth room conditions. P. harmala seeds were placed in pots to germinate the seeds. NaCl application to the seedlings was done at the 4th week of seedling growth. The plants were then respectively irrigated with NaCl solution for a period of 5-week. Following harvest, it was noted that fresh and dry weights of P. harmala increased with salinity levels. Chlorophyll-a and b, proline, and malondialdehyde and hydrogen peroxide contents as well as the activity of antioxidant enzymes such as catalase and peroxidase significantly increased as a result of treatments at concentrations between 150 and 300 mmol L-1 NaCl when compared to those of control plants (P < 0.05). The highest Na+ and Cl-ions were 78.8 and 68.1 mg g(-1) DW at 300 mmol L-1 NaCl, respectively. On the other hand, ion contents such as K+, Ca++ and Mg+ decreased under 150-300 mmol L-1 NaCl when compared to the control plants (P < 0.05). Removal of Na+ as the adjusted removal capacity per hectare under field conditions were 304.6 and 404.2 kg at 150- and 300 mmol L-1 NaCl concentrations. DNA damage measurement showed that DNA integrity of the halophyte preserved its uniform shape at 150- and 300 mmol L-1 NaCl according to measurements of the results of the comet assay. This study showed that P. harmala could well used to clean-up highly saline soils to regain them for agricultural purposes.
