Considering this complex morphology, it was postulated that certain subsection V-specific (cytoskeletal) proteins could be responsible for this phenotype. However, no specific gene was identified whose distribution was specifically correlated with the cell morphology among different cyanobacterial subsections.
The function of the cyanobiont depends on its host species. Abundant marine cyanobacteria in the genus Synechococcus form symbionts with dinoflagellates in the genera Ornithocercus, Histionesis and Citharistes, where it is hypothesized to benefit its host through the provision of fixed nitrogen in oligotrophic, subtropical waters.

Merismopedia (from the Greek merismos [division] and the Greek pedion [plain]) is a genus of cyanobacteria found in fresh and salt water. It is ovoid or spherical in shape and arranged in rows and flats, forming rectangular colonies held together by a mucilaginous matrix.
SynechoNET is a specialized cyanobacterial protein-protein interaction database. It shows feasible cyanobacterial domain-domain interactions, as well as their protein level interactions using the model cyanobacterium, Synechocystis sp. PCC 6803. Additionally, SynechoNET provides transmembrane topology and domain information, as well as ...
Microcystins are a group of potent heptapeptide hepatotoxins, which contains more than 85 known varieties, produced by different species of aquatic cyanobacteria. [12] Gloeotrichia echinulata are found in a variety of ecosystems, but tend to form large, potentially dangerous blooms in lakes with eutrophic and poor ecological status.
Synechococcus is one of the most important components of the prokaryotic autotrophic picoplankton in the temperate to tropical oceans. The genus was first described in 1979, [5] [6] and was originally defined to include "small unicellular cyanobacteria with ovoid to cylindrical cells that reproduce by binary traverse fission in a single plane and lack sheaths". [7]
Cyanobacteria were the first organisms to achieve photosynthesis. [4] Chlorophyll and phycocyanine—two pigments contained in cyanobacteria—allow the vegetative cells to absorb light and transform it into nutrients. [4] The genus Aphanizomenon is defined as a cluster of eight morphospecies, including Aphanizomenon flos-aquae. [5]
Cyanophages are viruses that infect cyanobacteria, also known as Cyanophyta or blue-green algae. Cyanobacteria are a phylum of bacteria that obtain their energy through the process of photosynthesis. [1] [2] Although cyanobacteria metabolize photoautotrophically like eukaryotic plants, they have prokaryotic cell structure.
