Extremely low levels of genetic polymorphism in endosymbionts (Buchnera) of aphids (Pemphigus).

Molecular ecology - 1 Dec 2002

Abbot P, Moran N A

Abstract excerpt

Molecular evolutionary studies have suggested that vertically transmitted endosymbionts are subject to accumulation of deleterious mutations through genetic drift. Predictions of this hypothesis for patterns of intraspecific polymorphism were borne out in the single relevant study available, on the symbiont Buchnera aphidicola of Uroleucon ambrosiae. In order to examine the generality of this result, we surveyed...
