Other claims from this paper (11)
- Intervention effect Extractable Rubisco activity in antisense leaves was 18% of controls.
- Intervention effect Leaf soluble protein was reduced in proportion to Rubisco.
- Intervention effect Phosphoribulokinase activity, electron transport and chlorophyll content changed little.
- Observation Carbonic anhydrase activity declined significantly.
- Intervention effect Antisense plant CO2 assimilation fell by 63%.
- Observation Rubisco limited assimilation across a broad range of intercellular CO2 pressure in antisense plants.
- Observation In control leaves Rubisco limited assimilation below 400 microbars.
- Observation Stomata still responded to intercellular CO2 changes.
- Mechanism Unchanged conductance and lower assimilation resulted in higher intercellular CO2.
- Observation Antisense leaves showed greater carbon isotope discrimination.
- Mechanism Stomatal function appeared independent of total leaf Rubisco activity.
