Fig. 4 Drought tolerance of transgenic SfPR1a tobacco A: phenotype of tobacco under drought stress treatment for two weeks; B: MDA content of tobacco under for two weeks drought treatment; C: phenotype of tobaccos under drought stress for four weeks and then re-water for one week. D: survival rate (D) of tobaccos under drought stress for four weeks and then re-water for one week. Bars labelled with different letters are significantly different at P < 0.05.
