Metabolic characteristics and evolutionary history of the nitrogen-fixing cyanobacterial endosymbionts of pennate diatoms

Abstract Nitrogen-fixing cyanobacteria are important sources of bioavailable nitrogen on Earth. Some nitrogen-fixing cyanobacteria are endosymbionts of algae, and recently one of them, UCYN-A2, was shown to be an early-stage organelle (nitroplast) of haptophytes. These biological...
