Other claims from this paper (8)
- Intervention effect Nitrogen infiltration affected CO2 compensation point similarly in both plants.
- Intervention effect Increased nitrogen stimulated T. triandra RuBP oxygenase activity by 500%.
- Intervention effect Z. mays RuBP oxygenase did not respond to nitrogen.
- Mechanism Glycolate and glyoxylate may serve as substrates for photorespiratory CO2 production of formate.
- Intervention effect T. triandra leaf formate levels rose with increased nitrogen infiltration.
- Intervention effect Z. mays leaf formate did not rise with nitrogen infiltration.
- Mechanism An alternative photorespiratory pathway may operate in T. triandra under high nitrogen.
- Mechanism The proposed pathway may increase nitrogen use and photorespiratory CO2 loss, decreasing productivity.
