Determination of drought tolerance of PtrA/NINV-overexpressing plants. a Plant phenotype of transgenic lines and wild type (WT) before and after a two-week water deprivation treatment and after a 3-days-recovery period (n = 20). Bar = 5 cm. Chlorophyll fluorescence imaging is shown below the relevant panels, and the false colour scale between 0 and 1 is presented. b Survival rates of transgenic lines and WT scored after the recovery. c Fv/Fm ratio of transgenic lines and WT before and after drought treatment. d Relative water loss rates measured during dehydration of leaves prepared from transgenic lines (#7 and #8) and wild type (n = 4). Each experiment was repeated at least twice. Statistically significant differences between the transgenic lines and WT at the same time points are shown (*P < 0.05, **P < 0.01, ***P < 0.001)
