Effector loss and gain drives pathogen host range at a fitness cost

Marcus Vinícius Merfa, Tracy E. Hawk, Jelmer W. Poelstra, Lillian Ebeling-Koning, Ervan Rodgers, Hannah Toth, Zachary M. Konkel, Jules Butchacas, Nathaniel Heiden, Muhammad Uzair, Temitope F. Oladele, Godwin Edet Oduokpaha, Rebecca D. Curland, Emmanuelle Lauber, Laurie Marsan, , Jonathan M. Jacobs

This study shows that gene loss and gain in Xanthomonas translucens drive host range shifts, with fitness costs for generalist behavior and enhanced virulence for specialist behavior.
