Leaf disc assay. (a) Stress tolerance exhibited by the leaf discs of WT and transgenic lines at various concentrations of NaCl (100, 200 and 300 mM) and (b) sorbitol 300, 400 and 500 mM treatments. Photographs were taken post 3 d NaCl and 5 d Sorbitol treatments. (c) Total chlorophyll and TBARS were measured in WT and transgenic leaf discs after 2 d NaCl treatment and after 4 d Sorbitol treatment. Values are means ± SE (n = 3), and each replicate comprises minimum 15 leaf discs. Different letters indicate significant difference (P ≤ 0.05) between each other. H1 and H2 represent high expression lines whereas Low represents low expression line seedlings.
