Physiological analysis of WT and <i>CsGolS6-</i>overexpressing transgenic tobacco plants under different water regimes in greenhouse conditions.

WT and transgenic (L3-L12) plants were exposed to three water regimes: (i) control (leaf water potential at -0.3 a -0.5 MPa), (ii) drought (leaf water potential at -1.5 a -2.0 MPa) and (iii) rehydration (leaf water potential at -0.3 a -0.5 MPa after a cycle of drought stress). The data are means ± SE of ten biological replicates. *,**Significantly different from WT at the respective water treatment by the Dunnett test at P ≤ 0.05 or P ≤ 0.01, respectively.
