from Julia P. Swiercz and Marie A. Elliot writing in Bacterial Spores: Current Research and Applications:
Streptomyces are soil-dwelling Gram positive bacteria with a complex, multicellular life cycle. The latter stages of their life cycle are defined by the metamorphosis of multi-genomic aerial hyphae into chains of unigenomic exospores. Here, we discuss the classical studies that established a solid genetic understanding of aerial development and sporulation, and highlight important new advances in the areas of cell division and spore septum placement, chromosome segregation and condensation during sporulation, and spore maturation.
