A wide diversity of Pantoea lineages are engaged in mutualistic symbiosis and cospeciation processes with stinkbugs

Pantoea are emerging as widespread bacteria engaged in associations with a variety of hosts, including plants, insects and humans. Recently, mutualistic Pantoea gut symbionts have also been reported in pentatomid stinkbugs. In the present study, we examine the incidence and evolutionary history of these Pantoea symbionts in pentatomid stinkbug populations from 14 species, characterising the processes that shape their diversity. We identify...
