AtRAF1 improved leaf photosynthesis and growth in tobAtL-R1. (A) Leaf gas-exchange measurements of CO2-assimilation rates at 25 °C under varying intercellular CO2 pressures (Ci) made at 1,000 µmol quanta m2/s illumination. Shown are the average of three measurements (±SD) made on the leaves analyzed in Fig. 2. (B) Comparison of the faster growth (as a function of plant height ± SD) of the tobAtL-R1 lines (n = 3) relative to tobAtL (n = 3) at 25 °C in a growth cabinet in air with 0.5% (vol/vol) CO2 under ∼400 ± 100 µmol quanta m2/s illumination. Both transplastomic genotypes grew slower than wild-type tobacco (wt, n = 3). (C) Phenotype of the plants at the respective age postcotyledon emergence (pce).
