Cyanobacterial cells range in size from 0.5-1 m to 40 m in diameter.Some filamentous cyanobacteria form heterocysts. Many unicellular and filamentous cyanobacteria have been screened for plasmids.Gendel, S. 1987. Plasmids in filamentous, nitrogen fixing cyanobacterium Nostoc. Mol. Gen. Filamentous cyanobacteria of the genus Lyngbya are important contributors to coral reef ecosystems, occasionally forming dominant cover and impacting the health of many other co-occurring organisms. Filamentous cyanobacteria that differentiate multiple cell types are considered the peak of prokaryotic complexity and their evolution has been studied in the context of multicellularity origins. Hutchins, David Allen, "Nitrogen and iron interactions in filamentous cyanobacteria" (1989).Siderophores, by definition, are inducible by iron deprivation and repressible by iron availability.
