Cyanobacterial cell division and cell growth mutant phenotypes in Synechocystis, Synechococcus, and Anabaena.Stars indicate gene essentiality in the respective organism. While one gene can be essential in one cyanobacterial organism/morphotype, it does not necessarily mean it is essential in all other cyanobacteria.
Nostoc, also known as star jelly, troll's butter, spit of moon, fallen star, witch's butter (not to be confused with the fungi commonly known as witches' butter), and witch's jelly, is the most common genus of cyanobacteria found in a variety of both aquatic and terrestrial environments that may form colonies composed of filaments of moniliform cells in a gelatinous sheath of polysaccharides. [1]
Cyanobacteria are found almost everywhere. Sea spray containing marine microorganisms, including cyanobacteria, can be swept high into the atmosphere where they become aeroplankton, and can travel the globe before falling back to earth. [22] Cyanobacteria are a very large and diverse phylum of photosynthetic prokaryotes. [23]
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. Cyanophages can be found in both freshwater and marine environments. [3]
Some types of cyanobacteria are endosymbiont and cyanobacteria have been found to possess genes that enable them to undergo nitrogen fixation. [ 165 ] Organisms typically establish a symbiotic relationship due to their limited availability of resources in their habitat or due to a limitation of their food source.
Gloeotrichia is a large (~2 mm) colonial genus of Cyanobacteria, belonging to the order Nostocales. [2] The name Gloeotrichia is derived from the appearance of the filamentous body with prominent mucilage matrix. Found in lakes across the globe, gloeotrichia are notable for the important roles that they play in the nitrogen and phosphorus cycles.
Oscillatoria is a genus of filamentous cyanobacteria. It is often found in freshwater environments. [1] Its name refers to the oscillating motion of its filaments as they slide against each other to position the colony to face a light source. [2] Oscillatoria uses photosynthesis to survive and reproduce.
Carboxysomes are present in all cyanobacteria and many other photo- and chemoautotrophic bacteria. Cyanobacteria are globally significant drivers of carbon fixation, and since they require carboxysomes to do so in current atmospheric conditions, the carboxysome is a major component of global carbon dioxide fixation.
