Differential fitness of mitochondrial DNA in perturbation cage studies correlates with global abundance and population history in Drosophila simulans.

Abstract excerpt

Mitochondria are often referred to as the powerhouse of the cell. However, research linking intraspecific differences in organismal fitness with genotypic mitochondrial DNA (mtDNA) variation has been hampered by the lack of variation in experimentally tractable species. This study examines whether fly lines harbouring three distinct Drosophila simulans mtDNA types (siI, -II and -III) exhibit differential fitness...
