The roles of positive and negative selection in the molecular evolution of insect endosymbionts.

Gene - 1 Aug 2005

Fry Adam J, Wernegreen Jennifer J

Abstract excerpt

The evolutionary rate acceleration observed in most endosymbiotic bacteria may be explained by higher mutation rates, changes in selective pressure, and increased fixation of deleterious mutations by genetic drift. Here, we explore the forces influencing molecular evolution in Blochmannia, an obligate endosymbiont of Camponotus and related ant genera. Our goals were to compare rates of sequence evolution in...
