Water loss of rd29A:LeNCED petunia under drought stress. Plants of non-transformed control and transgenic rd29A:LeNCED1-8F were grown in the pots filled with same amounts of UC mix soils under well-irrigated conditions for 5 weeks and were subjected to drought stress treatment by withholding water over a period of 9 days. The weights of each pot were measured daily in the morning and water loss was calculated. The arrows mark the points when all the plants showed wilting. Each time point is presented as the mean ± SD (n = 6). Different letters denote significant differences at the 0.05 level.
