Effect of abiotic stresses on AsA content in WT and transgenic plants. AsA content of 10-day-old WT and T3 generation transgenic plants overexpressing AtOxR were assessed after 12 h, 24 h, or 48 h treatment: (a) 150 mM NaCl; (b) 300 mM mannitol; (c) 50 μM CuCl2; (d) 3 mM H2O2. The means ± SDs of three replicates are shown. Statistical significance was determined using Student’s t-tests. * represents p < 0.05 and ** represents p < 0.01
