Figure 4.

Photosynthetic light responses are largely unchanged by maize chromosomal introduction. Photosynthetic assimilation rates (A) over a range of light intensities at ambient CO₂ for leaves of maize, oat, and OMA lines are shown. Each panel represents mean assimilation rates of maize and wild-type oat or chromosomal means of OMA lines. Results are expressed as means of at least three biological replicates ± se. Measurements were taken at 25°C, leaf vapor pressure deficit of less than 1.5 kPa, and [CO₂] of 380 µL L^–1.
