## 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
## Abstract Alteration in the pattern of heterocysts is observed when suspending ammoniaβgrown filaments of __Anabaena__ ARM 314 in a medium devoid of combined nitrogen source but supplemented with rifampicin. Paired as well as strings of 3β9 heterocysts were noticed. The electrophoretic protein pa
