Characterization of a model system for the study of Nostoc punctiforme akinetes

  journal={Archives of Microbiology},
Nostoc punctiforme is a filamentous cyanobacterium that is capable of dark heterotrophy and cellular differentiation into nitrogen-fixing heterocysts, motile hormogonia, or spore-like akinetes. The study of akinete differentiation at the molecular level has been limited by the asynchronous development and limited number of akinetes formed within a filament. A system in which to study the development and genetic regulation of akinetes was investigated using a zwf mutant lacking glucose-6… CONTINUE READING
