Drought stress analysis of wild-type plants and transgenic plants with OsMYB6. (A) Performance of 2-week-old seedlings from OsMYB6 transgenic and wild-type plants subjected to drought stress without water for 25 days and then recovered for 4 days. Transgenic and wild-type plants were growth in 13 cm deep circular plates filled with a 1:3 mixture of nutrient soil and vermiculite at 25°C under 16 h light/8 h dark. The experiment contained three biological replicates. (B) Survival rates of transgenic and wild-type plants under drought stress. Values represent means of n = 3 ± SD (Duncan test: ∗∗P < 0.01) from three independent biological experiments. (C) Proline content in the wild-type and transgenic plants (OE1, OE2, and OE3) under normal growth and drought stress conditions. (D) The relative electrolyte leakage in the leaves of wild-type and OsMYB6 transgenic plants under normal growth and drought stress conditions. (E) MDA content in the wild-type and transgenic plants under normal growth and drought stress conditions. (F) CAT activity in the wild-type and transgenic plants under normal growth and drought stress conditions. (G) SOD activity in the wild-type and transgenic plants under normal growth and drought stress conditions. Values represent (C–G) means of n = 30 ± SD (Duncan test: ∗∗P < 0.01) from three independent biological experiments.
