Transcriptional regulators ChlR and CnfR are essential for diazotrophic growth in nonheterocystous cyanobacteria.

Proceedings of the National Academy of Sciences of the United States of America - 6 May 2014

Abstract excerpt

Leptolyngbya boryana (Plectonema boryanum) is a diazotrophic cyanobacterium lacking heterocysts. How nitrogen fixation is regulated in filamentous nonheterocystous cyanobacteria remains unclear. Here we describe a large 50-kb nitrogen fixation (nif) gene cluster in L. boryana containing 50 genes. This gene cluster contains 14 nif genes (nifBSUHDKVZT and nifPENXW), two genes encoding transcriptional regulators...
