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 Internal CO2 concentration was higher in transformants than wild type, with 190 and 275 versus 175 μmol mol −1.
- 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.
- Mechanism Tobacco adjustment to avoid one sided Rubisco limitation is exhausted in extreme environmental conditions.
