Symbiosis: Creating a tractable intracellular insect-microbe association

Abstract

Endosymbioses are widespread among insects and have far-reaching implications for their hosts' ecology and evolution. However, the molecular underpinnings of symbiosis remain largely obscure. In a new study, Su et al. successfully established a transmissible synthetic symbiosis, opening up exciting new opportunities to explore the initial dynamics of endosymbiotic interactions.
