Can eukaryotes perform nitrogen fixation
WebBoth phototrophic and heterotrophic eukaryotes can harbour cyanobacterial symbionts. In the former case, the functional significance is probably always symbiotic N 2 fixation; the symbionts typically have a large number of heterocysts, and they fix N 2 at a high rate. In the latter case nitrogen fixation may or may not be an important aspect of ...
