Cell division gene ftsQ is required for efficient sporulation but not growth and viability in Streptomyces coelicolor A3(2)

We show that the cell division gene ftsQ of Streptomyces coelicolor A3(2) is dispensable for growth and viability but is needed during development for the efficient conversion of aerial filaments into spores. Combined with our previous demonstration that ftsZ of S. coelicolor is not needed for viability, these findings suggest that cell division has been largely co-opted for development in this filamentous bacterium. This makes S. coelicolor an advantageous system for the study of cell division genes.
