Light-response curves for the rate of photosynthetic CO₂assimilation in WT and GL. Shade-leaves, which exhibited identical green coloration in both WT and GL, were used for measurements. Light intensities of irradiation were changed from high to low. (•, blue), WT; (Δ, red), GL. Points are the means of three (•) or four (Δ) separate measurements ± SD.
