Independent duplications of the acetylcholinesterase gene conferring insecticide resistance in the mosquito Culex pipiens.

Abstract

Gene duplication is thought to be the main potential source of material for the evolution of new gene functions. Several models have been proposed for the evolution of new functions through duplication, most based on ancient events (Myr). We provide molecular evidence for the occurrence of several (at least 3) independent duplications of the ace-1 locus in… (More)
