Other claims from this paper (12)
- Intervention effect Starch content increased after PPFD increased.
- Intervention effect Removing all leaves except the fifth prevented a photosynthesis decrease when PPFD rose.
- Observation Stimulation of photosynthesis at 2.0 kPa oxygen did not decline.
- Observation The ratio of triose phosphate to 3-phosphoglycerate rose.
- Observation Intercellular carbon dioxide partial pressure did not decrease.
- Observation RuBP content did not decrease.
- Observation Photosynthesis per unit initial RuBPCO activity decreased.
- Association Growth-cabinet PPFD and leaf preconditioning PPFD affected initial RuBPCO activity.
- Association Growth-cabinet PPFD and leaf preconditioning PPFD affected standard RuBPCO activity.
- Mechanism The results suggest that a varying share of RuBPCO was membrane bound and insoluble in extracts.
- Mechanism The comparison suggests membrane-bound RuBPCO did not contribute to photosynthetic carbon fixation.
- Mechanism The authors propose membrane binding and release modulate actual RuBPCO activity in vivo.
