Introduction Gene duplications, losses, and horizontal transfers can facilitate dramatic shifts in bacterial lifestyle and capabilities (Romero and Palacios, 1997; Moran, 2002; Arnold et al., 2022). Gene loss is a dominant feature of symbiont evolution due to the selective benefits of removing metabolically costly genes (McCutcheon and Moran, 2012; McCutcheon et al., 2019). Alternatively, gene gain via horizontal transfer and duplication can lead to rapid adaptation across symbiotic species.
