Other claims from this paper (9)
- Observation Rice seedling nitrate reductase activity fluctuated daily.
- Intervention effect Dark placement slowly reduced nitrate reductase activity.
- Intervention effect Sunlight rapidly restored activity after darkness.
- Intervention effect Etiolated seedlings rapidly increased nitrate reductase activity in sunlight.
- Intervention effect Ethionine inhibited the sunlight increase in activity.
- Intervention effect Methionine reversed ethionine inhibition.
- Method / resource Nitrate reductase was purified about 40-fold from dark and sunlight plants.
- Observation In sunlight, nitrate reductase fraction specific radioactivity increased twofold relative to crude extracts.
- Observation Specific radioactivity did not increase in the dark.
