Genetic manipulation and tools in myxobacteria for the exploitation of secondary metabolism.

Myxobacteria are famous for their capacity for social behavior and natural product biosynthesis. The unique sociality of myxobacteria is not only an intriguing scientific topic but also the main limiting factor for their manipulation. After more than half a century of research, a series of genetic techniques for myxobacteria have been developed, rendering these mysterious bacteria manipulable. Here, we review the advances in genetic manipulation of myxobacteria, with a particular focus on the exploitation of secondary metabolism. We emphasize the necessity and urgency of constructing the myxobacterial chassis for synthetic biology research and the exploitation of untapped secondary metabolism.
