## Abstract Growth and urea regulation of heterocyst and nitrogenase formation have been studied in the diazotrophic cyanobacterium __Anabaena cycadeae__ and its glutamine auxotrophic mutant strain lacking glutamine synthetase (GS) activity. The parent strain having normal GS activity utilized urea

The arginine and proline inhibition of nitrite reductase and urease activities have been studied in the cyanobacterium Anabaena cycadeae and its mutant strain lacking glutamine synthetase (GS)') activity. Arginine and proline inhibited the nitrite reductase and urease activities in the parent strain
Nitrate uptake and reductase activities of the cyanobacterium Anabaena cycadeae and its mutant, lacking glutamine synthetase, (the glutamine auxotroph) were measured. The levels of both these enzymes were up to 25-fold higher in the mutant than in the parent (Anabaena cycadeae). The data indicate op
