Cloning of the mitochondrial genome of Anopheles quadrimaculatus.

The entire 15 kilobase (kb) Anopheles quadrimaculatus mitochondrial DNA (mtDNA) was cloned as three EcoRI fragments in a bacteriophage vector and then subcloned into plasmid vectors. The cloned DNA was physically mapped with restriction endonucleases, and the maps were compared to the restriction patterns of native A. quadrimaculatus mtDNA. Several genes were mapped by sequencing the ends of A. quadrimaculatus mtDNA subclones and by hybridization with the previously characterized Aedes albopictus mtDNA clones. These portions of the genetic map were identical in gene order to those of Drosophila yakuba. The predicted amino acid sequence of the protein coding regions that were sequenced were between 72% and 98% homologous to D. yakuba. The cloned mtDNA will be useful as a probe for population genetic analysis of mosquitoes.
