Other claims from this paper (9)
- Mechanism Two light-dependent oxidoreductases control chlorophyll synthesis in barley.
- Intervention effect porA mRNA concentration declines drastically during illumination.
- Observation Plastid import of pPORA declines during the transition to chloroplasts.
- Mechanism A rapid decline of plastid protochlorophyllide mediates reduced pPORA translocation.
- Observation PORA becomes selectively destabilized in illuminated seedlings.
- Mechanism Illuminated PORA complexes photoreduce Pchlide to Chlide and become susceptible to plastid proteases.
- Observation PORA-degrading protease activity is induced by illumination and absent in etioplasts.
- Observation PORB remains operative in illuminated and green plants.
- Mechanism PORB import into plastids does not depend on Pchlide.
