Unicellular bacteria, from the genus Anabena, from a microbial mat in Guerrero Negro, Baja California, Mexico.

Anabena is a genus that encompasses plankton species. They fall under a type of bacteria called cyanobacteria.[1] They have the ability to perform photosynthesis, as well as the ability to convert nitrogen in the air to ammonia, in water. They form mutually beneficial relationships, called symbiotic relationships with some plants. Anabena can make neurotoxins. It protects the plants from being eaten by wildlife. However, some species of Anabena have been used as a natural fertilizer in rice fields.

Genome[change | change source]

A study in 1999 has found the complete genome of Anabena (all of the DNA material). It is 7.2 million base pairs long. Anabena species have been used in research which focused on nitrogen fixation, DNA repair and primitive vision pigments.[2]
