(A) Diagram showing PCR primers used to detect the. Description and Significance. Anabaena provides a model for the study of gene differentiation in the formation of heterocysts.
The recent.Effects of Microcystis inoculation Anabaena scum on AU pond S1 Large-scale, pond inoculation of Microcystis The Anabaena is a genus of filamentous – cyanobacteria, or blue . At the onset of nitrogen limitation during bloom conditions, certain cells in Anabaena and Aphanizomenon evolve into heterocysts, which convert nitrogen gas into ammonium, which is then distributed to the neighboring cells of a filament.
(iv) The cell organelle like chloroplast, mitochondria, endoplasmic reticulum are absent. The mitotic and meiotic cell divisions do not occur.

One of the most frequently encountered of the cyanobacteria in fresh water locations. Here is a diagram of Anabaena. A cluster of filaments of the cyanobacterium Anabaena. The highly refractile bright spherical bodies are the heterocysts, the sites of nitrogen fixation in this genus.
