The intriguing evolutionary dynamics of plant mitochondrial DNA

Abstract

The mitochondrial genome of plants is-in every respect and for yet unclear reasons-very different from the well-studied one of animals. Thanks to next-generation sequencing technologies, Davila et al. precisely characterized the role played by recombination and DNA repair in controlling mitochondrial variations in Arabidopsis thaliana, thus opening new perspectives on the long-term evolution of this intriguing genome © 2011 Galtier; licensee BioMed Central Ltd.
