Method Extracted by eye from figures 4A-B.
Comments "Photosynthetic activity in wild-type and transformed plants: The CO2 assimilation rate under increasing irradiance and intercellular CO2 concentrations was measured in the fourth leaves from the top of wild-type (o), TpFS-6 (?), and TpFS-3 (?) plants after 12 weeks of culture. (A) Effect of increasing irradiance on CO2 assimilation at 360 p.p.m. of CO2, 25°C, and 60% relative humidity. (B) Response of CO2 assimilation rates to increasing intercellular CO2 concentrations (Ci) at irradiance (400 µmol/m^2/s)."
