Why do Streptomycetes have ability to produce so many specialised molecules?

Various streptomycete soil bacteria have ability to produce a range of molecules called secondary metabolites.

See if you can relate a specialised molecule, or streptomycete general metabolic versatility, to one of the following aspects of streptomycete biology.

  1. Habitat
  2. Life-cycle
  3. Cell fusion between different vegetative hyphae
  4. Presence of conjugative plasmids
  5. Nutrition and nutrient capture
  6. Chromosomal structure
  7. QS
  8. Membrane physiology
  9. Stress - UV exposure, dehydration
  10. Aerial hyphae
  11. Spore survival

Good luck.
