Microsatellite markers for interspecific mapping of Drosophila simulans and D. sechellia

The sister species Drosophila simulans and D. sechellia provide an excellent system for investigating the genetics of speciation and adaptation. The two species have different ecologies and differ markedly in a number of reproductive traits (R'Kha et al. 1991; Coyne et al. 1991). Attempts have...

Description
Summary:The sister species Drosophila simulans and D. sechellia provide an excellent system for investigating the genetics of speciation and adaptation. The two species have different ecologies and differ markedly in a number of reproductive traits (R'Kha et al. 1991; Coyne et al. 1991). Attempts have been made to localize genes responsible for these differences. However, the number of markers employed was limited (Joly et al. 1997; Jones 1998). The development of a relatively dense genetic map for D. simulans and D. sechellia will allow more powerful analyses to be undertaken. Most published Drosophila sequences were characterized from D. melanogaster. The close relationship between D. melanogaster, and the D. simulans complex (D. simulans, D. sechellia and D. mauritiana) implies that a reasonable fraction of these microsatellites should be informative in all four species. We screened microsatellites selected from D. melanogaster in order to develop genetic markers for mapping studies in the D. simulans group.
