X. Z. Li; A. Oaks PLANT PHYSIOLOGY 1994. doi:10.1104/pp.106.3.1145
Other claims from this paper (7)
- Intervention effect Shoot nitrate reductase activity and mRNA decayed immediately after dark transfer.
- Intervention effect Shoot nitrate reductase protein changed only slightly during the first four hours of darkness.
- Intervention effect Root nitrate reductase activity, protein and mRNA loss was delayed four hours after dark transfer.
- Intervention effect Shoot NRA recovered to 92% of initial levels within 30 minutes after return to light.
- Mechanism Authors infer that darkness inactivates the light-induced active NR protein.
- Mechanism NR protein can reactivate after light follows a two-hour dark interval.
- Mechanism Root response probably follows photosynthetically produced metabolites rather than immediate light-reaction products.
