A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...rstanding the forces driving this mode of genome evolution, as well as the consequences on the fitness of the bacterium and its host. "Developments in endosymbiosis are important not only to questions in basic research, but may have important practical implications," notes Wernegreen. "A very promising area of end...
