The Jekyll and Hyde Symbiont: Could Wolbachia Be a Nutritional Mutualist?

The most common intracellular symbiont on the planet-Wolbachia pipientis-is infamous largely for the reproductive manipulations induced in its host. However, more recent evidence suggests that this bacterium may also serve as a nutritional mutualist in certain host backgrounds and for certain metabolites. We performed a large-scale analysis of conserved gene content across all sequenced Wolbachia genomes to infer potential nutrients made by...
