Strain PCC 7120" A – according to Gollerbakh et al. It has filamentous structure. Due to these adaptations, the rate of oxygen diffusion into heterocysts is 100 times lower than of vegetative cells. Sometimes it becomes difficult to differentiate between trichomes of Nostoc and Anabaena. Therefore, heterocysts have developed elements to maintain a low level of oxygen within the cell. Sheaths are always hyaline and watery gelatinous. It also reveals cross-resistance against the herbicide 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU), drug bacitracin, and LiCl.

The Akinetes can survive dry conditions. upon salt stress (Ning et al., 2002).Salt induced disintegration of the plasmalemma and enhanced endonuclease activity resulted in DNA fragmentation, suggesting programmed death rather than lysis. Two contrasting cyanobacterial species ( Anabaena fertilissima and Anabaena sphaerica ) were selected based on differences in antifungal behavior in order to study the mechanism for production of an antifungal enzyme and the genes responsible for this production. Akinetes are thick walled spores with a large amount of reserved food material.
