Relative electrolyte leakage (REL) (A,D), relative MDA content (B,E) and relative water content (C,F) in PmLEAs transgenic tobacco lines after cold or drought treatments. Two-month-old transgenic lines were treated at 4°C for 24 h for cold stress. For drought treatment, water was withheld from transgenic tobaccos for 15 days. Three lines for PmLEA10 (10-4, 10-8, and 10-12), three lines for PmLEA19 (19-11, 19-22, and 19-27), two lines for PmLEA20 (20-6 and 20-9), and three lines for PmLEA29 (29-4, 29-6, and 29-8) were included. Three Lines transformed with empty vector (17-2, 17-10, and 17-13) were used as control. The relative changes were normalized with levels under normal condition (room temperature and well-watered). The data are presented as the mean values of three replicates ± SD. ∗, 0.01 < P < 0.05; ∗∗, P < 0.01 (Student’s t-test). Three independent experiments were performed and gave similar results.
