Leaf gas exchange and water potential in LeNCED1-overexpressed petunia. Plants of non-transformed control, transgenic rd29A:LeNCED1 lines 8F, 7D, 3D, and CaMV-35S:LeNCED1-12F line were grown in UC mix soils in greenhouse for 6 weeks under non-stress conditions and were subjected to drought treatment by withholding irrigation for 3 days. CO2 assimilation rate (a), leaf conductance (b), transpiration rate (c), and stem water potential (d) were measured using intact leaves. Error bars represent standard deviation of the mean where n = 6. Different letters denote significant differences at the 0.05 level.
