Identification of a gene regulated by HetR, a master regulator of heterocyst differentiation, in the non-heterocyst-forming filamentous cyanobacterium Arthrospira platensis NIES-39.

Abstract excerpt

Cyanobacteria are a morphologically and physiologically diverse group of bacteria, which contains unicellular and multicellular filamentous strains. Some filamentous cyanobacteria, such as Anabaena sp. strain PCC 7120, form a differentiated cell called a heterocyst. The heterocyst is a specialized cell for nitrogen fixation and is differentiated from a vegetative cell in response to depletion of combined nitrogen...
