Abstract Animal-microbe symbioses are omnipresent, where both partners often gain benefits as mutualists. How such mutualism has evolved between originally unrelated organisms is of interest. Here we report that, using an experimental symbiotic system the stinkbug Plautia stali and model bacterium Escherichia coli , disruption a single bacterial gene tnaA encoding tryptophanase makes E. mutualistic to P. . Survey natural mutualists across wild populations other species uncovered that their Pantoea -allied symbionts consistently lack gene. Some like ananatis retain cannot establish symbiosis with but -disrupted partially restored capability. When mutualist was transformed functional tna operon, its capability reduced significantly. Our finding suggests may have facilitated evolution gut in insects.
