Intraspecific variation in symbiont genomes: bottlenecks and the aphid-buchnera association.

Genetics - 1 Feb 2001

Funk D J, Wernegreen J J, Moran N A

Abstract excerpt

Buchnera are maternally transmitted bacterial endosymbionts that synthesize amino acids that are limiting in the diet of their aphid hosts. Previous studies demonstrated accelerated sequence evolution in Buchnera compared to free-living bacteria, especially for nonsynonymous substitutions. Two mechanisms may explain this acceleration: relaxed purifying selection and increased fixation of slightly deleterious...
