Other claims from this paper (5)
- Observation Chloroplast protein targeting was unaffected in mgd1 mutants.
- Observation The photoactive to photoinactive Pchlide ratio increased in dark-grown mgd1 plants.
- Observation mgd1 plants could not withstand high light intensities.
- Mechanism Increased thylakoid membrane conductivity raised interior pH and impaired VDE and PsbS activation.
- Mechanism MGDG was interpreted to contribute directly to regulation of photosynthesis-related processes.
