Comparisons of germination rate and growth between ThbZIP1 transformed and Col-0 plants. A: RT-PCR detected the expression of exogenous ThbZIP1 in transgenic plants. B: The growth of ThbZIP1 transformed and Col-0 plants under salt, drought, ABA and normal growth conditions; a, b, c, plants under the conditions of normal growth (a), salt (b), drought (c), and ABA (d). C: A comparison of the seed germination rates between ThbZIP1 transformed and Col-0 plants under normal growth condition (a), salt (b), drought (c) and ABA (d) stress conditions; D: An analysis of root growth (a, b, c), fresh weight (d, e, f) and germination rate (g, h, i) of ThbZIP1 transformed and Col-0 plants under salt, drought and ABA stress conditions. Data are means ± SD from three independent experiments. * Significant (t test, P < 0.05) difference compared with Col-0 plants.
