Abstract
ABSTRACT
In contrast to genome size variation in most bacterial taxa, the small genome size of
Buchnera
sp. was shown to be highly conserved across genetically diverse isolates (630 to 643 kb). This exceptional size conservation may reflect the inability of this obligate mutualist to acquire foreign DNA and reduced selection for genetic novelty within a static intracellular environment.
