Anabaena Synechococcus In all our experiments, filaments were long enough so that any possible end effects were negligible. Consequently, the behavior we observed throughout ALL experiments was ...

Here, we directly visualise molecular exchange between cells in several Anabaena species by loading calcein, a small hydrophilic fluorophore, into the cytoplasm. We use fluorescence recovery after ...

Anabaena sp. PCC 7120 is a nitrogen-fixing filamentous cyanobacterium. Under nitrogen-limiting conditions, a fraction of the vegetative cells in each filament terminally differentiate to nongrowing ...

Anabaena variabilis ATCC 29413 has two distinct nitrogenases that function in heterocysts, a conventional Mo-nitrogenase and an alternative V-nitrogenase. Synthesis of these two enzymes was repressed ...

The Role of Isotopes in Studies on Nitrogen Fixation and Nitrogen Cycling by Blue-green Algae and the Azolla-anabaena Azollae Association ... IAEA-TECDOC -325 English IAEA-TECDOC-325 164 pages ¦ € ...

The gene cyaB1 from the cyanobacterium Anabaena sp. PCC 7120 codes for a protein consisting of two N‐terminal GAF domains (GAF‐A and GAF‐B), a PAS domain and a class III adenylyl cyclase catalytic ...

Electron microscopy reveals that the multicellular hairs, in the Anabaena-containing leaf cavities of Azolla, produce labyrinthine wall ingrowths, and have dense cytoplasm with numerous mitochondria ...
