Figure 10.

Carbohydrate amounts in leaf 5 of tobacco. Plants were grown at ACO₂ or ECO₂ and either well watered (A and B) or experiencing a moderate water deficit (C and D). Shown are the amount of Suc (A and C) and starch (B and D). Data are presented for the wild type (WT; gray bars), AOX overexpressors (B8, left black bars; B7, right black bars), and AOX knockdowns (RI9, left white bars; RI29, right white bars). Sampling was done at the midpoint of the light period. Each experiment included single individuals for each plant line and growth condition. Data are means ± se of three independent experiments (n = 3). Within a growth condition, 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. DW, Dry weight.
