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
