Fig. 3.

CO₂ assimilation rate of transformed lines over a range of intercellular pCO₂ (C_i). Average of three T₂ plants from each line. Plants were grown at 2% CO₂, and the uppermost, fully expanded leaves of 5-week-old plants were measured using a LI-6400XT at 25 °C leaf temperature at an irradiance of 1500 µmol photons m⁻² s⁻¹. Arrows mark ambient pCO₂ for each line; note that the dotted arrow is line 1.1.
