Biological nitrogen fixation (BNF), a key reaction of the nitrogen cycle, is catalyzed by the
enzyme nitrogenase. The best studied isoform of this metalloenzyme requires molybdenum …

The enzyme molybdenum nitrogenase converts atmospheric nitrogen gas to ammonia and
is of critical importance for the cycling of nitrogen in the biosphere and for the sustainability …

Biological nitrogen fixation, the reduction of chemically inert dinitrogen to bioavailable
ammonia, is a central process in the global nitrogen cycle highly relevant for life on earth. N2 …

Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in
diverse plant lineages, offering a unique window to study the evolution and genetics of plant …

The reduction of atmospheric dinitrogen by nitrogenase is a key component of terrestrial
nitrogen cycling. Nitrogenases exist in several isoforms named after the metal present within …

Species of the floating, freshwater fern Azolla form a well-characterized symbiotic
association with the non-culturable cyanobacterium Nostoc azollae, which fixes nitrogen for …

Photosynthesis, the ability to fix atmospheric carbon dioxide, was acquired by eukaryotes
through symbiosis: the plastids of plants and algae resulted from a cyanobacterial symbiosis …

The filamentous cyanobacterium Anabaena variabilis ATCC 29413 fixes nitrogen under
aerobic conditions in specialized cells called heterocysts that form in response to an …

For over 50 years scientists have considered the possibility of engineering a plant with
nitrogen fixation capability, freeing farmers from their dependence on nitrogen fertilizers …

Cyanobacteria are widely distributed in marine, aquatic, and terrestrial ecosystems, and play
an important role in the global nitrogen cycle. In the present study, we examined the genome …
