Two mitochondrial genes under episodic positive selection in subterranean octodontoid rodents.

Gene - 25 Jan 2014

Tomasco Ivanna H, Lessa Enrique P

Abstract excerpt

Tuco-tucos (Ctenomys) and related coruros (Spalacopus) are South American subterranean rodents. An energetically demanding lifestyle within the hypoxic, underground atmosphere may change the selective regime on oxidative phosphorylation. We examined whether weak and/or episodic positive directional selection affected the evolution of two mitochondrial genes (COX2, CytB), in a background of purifying selection in...
