Relative abiotic stress tolerance of wild-type (WT) and AtOxR-transgenic plants. (a) RNA gel blot analysis of T3 transgenic plants expressing AtOxR. WT: Arabidopsis thaliana ecotype Columbia-0; #1, #2, and #3: T3 seedlings with AtOxR on a Columbia-0 background. (b–j) Growth of WT plants and transgenic AtOxR plants (#1–3) on medium containing 1/2 MS (B), 100 and 125 mM NaCl (c–d), 100 and 200 mM Mannitol (e–f), 10 and 50 μM CuCl₂ (g–h), and 1 and 2 mM H₂O₂ (i–j) for 14 days. (k–n) Root lengths of WT and AtOxR transgenic plants were measured after treatment. Each value represents the means ± SE of 15 plants. Statistical significance was determined using Student’s t-tests. *represents p < 0.05 and **represents p < 0.01
