Figure 4From: Enhanced tolerance of transgenic potato plants expressing choline oxidase in chloroplasts against water stressChanges in photosynthetic parameters of non-transgenic (NT) and transgenic (SC) potatoes during and after water stress. A: photosynthetic rate (Pn), B: Stomatal conductance (Gs), C: Intercellular carbon dioxide concentration (Ci), D: Transpiration rate. Data are expressed as the mean ± standard deviation (SD) of five replicates.Back to article page
