Effects of different levels of NaCl stress on (a) net photosynthetic rate, (b) stomatal conductance, (c) transpiration rate, and (d) instantaneous water use efficiency from gas exchange for the non-transgenic control (CK) and the transgenic lines with ‘High’ (T3 and T13) expressions (as ranked in Table 2). Significant differences among means over the NaCl-stress treatments were determined according to Tukey’s HSD test at P < 0.05. The line bars are standard errors (n = 9, i.e., 3 replicates × 3 runs of the experiment)
