Unexpected Presence of the Nitrogen-Fixing Symbiotic Cyanobacterium UCYN-A in Monterey Bay, California [PDF]
Journal of Phycology, 2020 In the last decade, the known biogeography of nitrogen fixation in the ocean has been expanded to colder and nitrogen‐rich coastal environments. The symbiotic nitrogen‐fixing cyanobacteria group A (UCYN‐A) has been revealed as one of the most abundant and widespread nitrogen‐fixers, and includes several sublineages that live associated with genetically

Unusual Marine Unicellular Symbiosis With the Nitrogen-Fixing Cyanobacterium UCYN-A [PDF]
Nature Microbiology, 2016 Nitrogen fixation - the reduction of dinitrogen (N2) gas to biologically available nitrogen (N) - is an important source of N for terrestrial and aquatic ecosystems. In terrestrial environments, N2-fixing symbioses involve multicellular plants, but in the marine environment these symbioses occur with unicellular planktonic algae.

UCYN-a/Haptophyte Symbioses Dominate N2 Fixation in the Southern California Current System [PDF]
ISME Communications, 2021 Abstract The availability of fixed nitrogen (N) is an important factor limiting biological productivity in the oceans. In coastal waters, high dissolved inorganic N concentrations were historically thought to inhibit dinitrogen (N2) fixation, however, recent N2 fixation measurements and the presence of the N2-fixing UCYN-A/haptophyte ...
