Stress tolerance of overexpressing ThNAC7 in Arabidopsis. (A): Growth phenotype of transgenic and Col-0 plants under normal (1/2 MS), salt (150 mM NaCl), or osmotic (150 mM mannitol) stress. (B): Root length assay. (C): Analysis of fresh weight. (D): Chlorophyll content assay. The plants were cultured in 1/2 MS (as control) or 1/2 MS containing 150 mM NaCl or 150 mM mannitol for 14 days for the above analysis. (E): Growth phenotype of Arabidopsis plants. (F): Fresh weight of Arabidopsis seedlings. Three weeks old Arabidopsis seedlings in soil were treated with 400 mM mannitol or 250 mM NaCl for 2 weeks, then took a photograph of their phenotypes. Control: Plants growing in normal conditions. The asterisks (p < 0.05) show * significant differences compared to Col-0 Arabidopsis. Col-0: wild-type Arabidopsis plants; OE2 and 5: Arabidopsis lines 2 and 5 transformed with ThNAC7.
