Other claims from this paper (8)
- Intervention effect Ammonium reduced oxalate level in rice.
- Observation Nitrogen treatments changed glycolate, oxaloacetate and malate in a similar pattern.
- Intervention effect Exogenous glycolate almost completely restored the oxalate level decreased by ammonium.
- Observation GLO mRNA, protein and in vitro activity differed little between nitrogen treatments.
- Observation GLO kinetic constants for glycolate, glyoxylate and oxalate remained almost the same under nitrate and ammonium feeding.
- Intervention effect Estradiol induced GLO antisense expression reduced GLO protein levels and activities.
- Intervention effect Estradiol treatment did not significantly alter oxalate levels in transgenic rice.
- Mechanism The authors suggest oxalate accumulation and regulation is independent of GLO in rice leaves.
