Abstract
Primary production in a large fraction of the surface ocean communities is limited by the availability of nitrogen (N). Heterocyst-forming cyanobacteria associated with diatoms of the genera <italic>Hemiaulus, Rhizosolenia</italic>, and <italic>Chaetoceros</italic> can dominate surface communities throughout the global oceans, and are an important source of N to these communities. Additionally, these unique associations are directly linked to a highly efficient carbon export system. In order to study the nature and evolution of these symbioses, the genomes of representatives of symbionts from the three common diatom associations were sequenced. The genomes revea...
