FIGURE 4.
The ERF1 -V overexpression plants showed higher tolerance to drought stress. (a) The transgenic plants and Yangmail58 grew well in the 1/2 Hoagland solution, and showed no phenotypic differences. (b) The transgenic plants showed higher tolerance to drought than Yangmail58 3 days after 20% PEG-6000 treatment. (c) The transgenic plants recovered quickly 1 day after re-watering while the Yangmail58 remained wilted.
