Emergence and evolution of Arsenophonus bacteria as insect-vectored plant pathogens

- Arsenophonus bacteria are among the most biologically diverse and widespread arthropod endosymbionts.
- Two species: Phlomobacter fragariae and Arsenophonus phytopathogenicus have been characterized as emerging insect-vectored plant pathogens.
- Information on the evolution, lifestyle transition, infection cycles, and interaction with hosts are reviewed.
