Characterization of Two Genes Up-regulated During Heterocyst Development in the Cyanobacterium Anabaena sp. strain PCC 7120.
Anabaena sp. strain PCC 7120 is a cyanobacterium that carries out photosynthesis in a manner similar to plants and is capable of nitrogen fixation. This organism has developed a necessary spatial separation of the incompatible processes of photosynthesis and nitrogen fixation, as nitrogen fixation …
