Fig. 4From: Cucumber Phospholipase D alpha gene overexpression in tobacco enhanced drought stress tolerance by regulating stomatal closure and lipid peroxidationShoots and roots fresh weights (a, c) and dry weights (b, d) of wild type (WT) and transgenic tobacco seedlings were measured after drought stress treatment of 0, 8 and 16 d, separately. Values are means ± SD (n = 3). * and ** Significant at P < 0.05 and P < 0.01 compared with WT, respectivelyBack to article page
