Fresh weight and root architecture comparison of non-transformed (WT) plants and two EsDREB2B transgenic tobacco lines under osmotic, salt, cold and heat stresses. For osmotic and salt stresses, the two-week old seedlings grown on MS medium transplanted to MS medium supplemented with 200 mM mannitol and 200 mM NaCl for 20 d. For cold and heat stresses, the two-week-old seedlings grown in MS medium were treated for 20 d at 4°C or 7 d at 42°C, respectively. For non-stress control (NS), seedlings were grown in MS culture and kept in normal growth conditions (at 28°C). All plants were grown on vertical MS Plates. A fresh weight (expressed in mg), B root length (expressed in cm), and C lateral root number were determined after treatments. Results are presented means ± SE (n = 24 seedlings). a–b: there are no significant differences (p ≥ 0.05) between the lines with the same characters, and significant differences (p < 0.05) between lines with different characters. Significant difference comparison was carried out within stress.
