Fig. 2. — Changes in assimilatory quotient with the shift from to (ΔAQ) as a function of photosynthetic PFD in shoots of A. thaliana cv. Columbia. Thirty-six-day-old wild-type plants (A), 48-d-old wild-type plants (B), a genotype with mutations in the two structural genes for reductase (nia1 nia2) (C), and a transgenic line harboring the chimeric gene Lhch1^*3::Nia1^*2 (D). The plants were grown under ambient CO₂ (360 μmol·mol^-1) and measured under ambient CO₂ and O₂ (360 μmol·mol^-1 CO₂ and 21% O₂; circles), elevated CO₂ (720 μmol·mol^-1 CO₂ and 21% O₂; triangles), or low O₂ (360 μmol·mol^-1 CO₂ and 2% O₂; squares). Shown are the mean ± SE, n = 5-8 plants.
