Changes in RL and EPsat as a function of growth irradiance and leaf water status in WT tobacco and transgenic tobacco lines with altered amounts of AOX protein. Plants were grown at 150 PPFD (A), 400 PPFD (B), or 700 PPFD (C) under well-watered conditions for 19 to 21 days, followed by water being withheld from the plants for up to an additional 6 days. At different times following the water being withheld, leaf RL and EPsat were determined. Data are shown for WT plants (gray circles), AOX overexpressors (black circles; half are B7, half are B8) and AOX knockdowns (white circles; half are RI9, half are RI29). The data points are compiled from three to five independent experiments.
