Cell size and heterocyst differentiation in nostocacean blue-green algae.

Cytobios, 1981
Cell size variations in three heterocystous blue-green algae, viz. Nostoc muscorum (ISU strain), N. muscorum (UW strain) and N. calcicola (a local isolate) have been surveyed under conditions permissive and non-permissive of heterocyst differentiation. A monomodal distribution pattern was observed for the two strains of N. muscorum under conditions not

The heterocysts of blue-green algae. III. Differentiation and nitrogenase activity

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1972
The course of heterocyst development in Anabacna cylindrica was studied in relation to the ability to fix nitrogen. When non-differentiated filaments, grown in the presence of ammonium-N, were transferred into a medium free from combined nitrogen and incubated under photosynthetic conditions, the cellular C:N ratio ...
