Photosystem II electron transport rate in nontransformed and two independent, fifth generation transgenic plants grown under control conditions. The electron transport rate under increasing irradiance was calculated from chlorophyll fluorescence measurements on the youngest fully expanded leaf of NTC (▴), R80 (▪), and A05 (•) at 360 ppm of CO₂, 25°C, and 50% relative humidity after 10 weeks of growth. Values are the means ± SD (n = 9). Data are normalized to the average light-saturated rate of the nontransgenic control plants.
