e0“the internal CO 2 concentration (c;) was higher in the transformants than in the wild‐type (190 and 275 μmol mol −1 in plants with 35 and 80% less Rubisco, respectively, compared with 175 μmol mol −1 for wild‐type)”

Other claims from this paper (7)
- Observation Transformed tobacco had Rubisco contents 35, 80 and over 90% lower than wild type.
- Association Rubisco content and photosynthetic rate had a near linear relation in high irradiance, with a flux control coefficient of 0.83–0.89.
- Observation Stomatal conductance remained unchanged or increased in plants with less Rubisco despite lower CO2 assimilation.
- Observation CO2 assimilation rate was lower in plants with decreased Rubisco.
- Observation Water use efficiency declined.
- Observation Apparent growth rate did not decline stoichiometrically with decreased photosynthesis.
- Mechanism Tobacco adjustment to avoid one sided Rubisco limitation is exhausted in extreme environmental conditions.
