Other claims from this paper (8)
- Intervention effect Light increased PEPCase V(max) more in maize than tobacco.
- Intervention effect Light decreased malate sensitivity in nitrogen-replete maize.
- Intervention effect Light did not decrease malate sensitivity in nitrogen-deficient tobacco.
- Intervention effect Nitrate increased PEPCase V(max) in maize.
- Intervention effect Nitrate increased PEPCase V(max) in tobacco.
- Intervention effect Nitrate-treated maize leaves had greater PEPCase kinase activity than chloride controls.
- Association Foliar glutamine content correlated with PEPCase activity.
- Mechanism The authors conclude that nitrogen metabolites increase flow through the anapleurotic pathway via PEPCase sensitivity.
