Figure 3From: Enhanced tolerance of transgenic potato plants expressing choline oxidase in chloroplasts against water stressThe determinations of Glycinebetaine contents and leave water potential in potatoes. GB levels (A) and leaf water potential (B) in non-transgenic (NT) and transgenic (SC) plants under water stress simulated with 20% PEG. GB was extracted from non-treated and 20% PEG-treated plants. Samples were collected after 48 h of PEG treatment. Data are expressed as the mean ± standard deviation (SD) of five replicates.Back to article page
