Fig. 2.
Photosynthesis-related parameters of tobacco leaf at different times during a prolonged water deficit and measured at the growth irradiance. (A) A. (B) gs. (C) T. (D) iWUE. Data are shown for WT (gray bars), AOX overexpressors (B8, left closed bar; B7, right closed bar), and AOX knockdowns (RI9, left open bar; RI29, right open bar). Data are the mean±SE of three independent experiments (n=3). Within each data set, plant lines not sharing a common letter are significantly different from one another (P<0.05). In data sets without letters, there are no significant differences across plant lines.
