Can eukaryotes fix nitrogen
WebDec 12, 2024 · State of the art in eukaryotic nitrogenase engineering. Abstract Improving the ability of plants and plant-associated organisms to fix and assimilate atmospheric nitrogen has inspired plant biotechnologists for decades, not only to alleviate negative effects on nature from increased use and availability of reactive nitrogen, but also … 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 ...
