Other claims from this paper (9)
- Observation Mutant M(4) progeny had greater net photosynthesis than wild type at 21 and 42% O(2).
- Observation About 60% of M(4) progeny segregated high catalase phenotypes averaging 40% greater than wild type.
- Association High catalase phenotype cosegregated with oxygen resistant photosynthesis.
- Observation NADH-hydroxypyruvate reductase activity in high-catalase mutants matched wild type.
- Observation Mutants released 15% less photorespiratory CO(2) at 21% O(2).
- Observation Mutants released 36% less photorespiratory CO(2) at 42% O(2).
- Observation Mutant leaf tissue released less labeled CO(2) per glycolate metabolized than wild type.
- Mechanism The authors attributed oxygen resistant photosynthesis to decreased photorespiration.
- Mechanism The authors proposed that higher catalase activity may reduce keto acid peroxidation by photorespiratory peroxide.
