Other claims from this paper (8)
- Observation Symbiont-free Azolla could be maintained only with combined nitrogen.
- Observation Anabaena azollae was confined to the Azolla leaf cavity.
- Method / resource Pure preparations of Anabaena azollae and Azolla chloroplasts were isolated.
- Observation Isolated Anabaena azollae could not be grown independently.
- Observation Both photosystems in the algal fraction were repressed relative to free-living Anabaena cylindrica.
- Observation The photosystem I to II ratio may be greater in Anabaena azollae.
- Observation Azolla chloroplasts were generally comparable to spinach chloroplasts.
- Observation Anabaena azollae contributed an estimated 7.5 to 15% of total chlorophyll in symbiotic Azolla.
