Genetic and Transgenic Reagents for Drosophila simulans, D. mauritiana, D. yakuba, D. santomea, and D. virilis
Species of the Drosophila melanogaster species subgroup, including the species D. simulans, D. mauritiana, D. yakuba, and D. santomea, have long served as model systems for studying evolution. However, studies in these species have been limited by a paucity of genetic and transgenic reagents. Here, we describe a collection of transgenic and genetic strains generated to facilitate genetic studie...
متن کاملGenetic studies of two sister species in the Drosophila melanogaster subgroup, D. yakuba and D. santomea.
We performed genetic analysis of hybrid sterility and of one morphological difference (sex-comb tooth number) on D. yakuba and D. santomea, the former species widespread in Africa and the latter endemic to the oceanic island of São Tomé, on which there is a hybrid zone. The sterility of hybrid males is due to at least three genes on the X chromosome and at least one on the Y, with the cytoplasm...
متن کاملProposal for the Sequencing of Drosophila yakuba and D. simulans
Overview Comparative genome sequencing has the greatest impact on biology when the targeted genomes impinge directly on analysis or interpretation of the human genome or the genome of a genetic model system. Comparative genomics may also shed light on the genetic and evolutionary mechanisms that determine genome organization and composition. The most obvious benefit of comparative genomics has ...
متن کاملMultilocus analysis of introgression between two sympatric sister species of Drosophila: D. yakuba and D. santomea
3 Drosophila yakuba is widely distributed in sub-Saharan Africa, while D. santomea is endemic to the volcanic island of São Tomé in the Atlantic Ocean, 280 km west of Gabon. On São Tomé, D. yakuba is found mainly in open lowland forests, while D. santomea is restricted to the wet misty forests at higher elevations. At intermediate elevations, the species form a hybrid zone where hybrid males oc...
متن کاملContrasting molecular population genetics of four hexokinases in Drosophila melanogaster, D. simulans and D. yakuba.
As part of a larger study contrasting patterns of variation in regulatory and nonregulatory enzymes of the central metabolic pathways we have examined the molecular variation in four uncharacterized hexokinase genes unique to muscle, fat body, and testis in Drosophila melanogaster, D. simulans, and D. yakuba. Earlier isoenzyme studies had designated these genes as Hex-A, Hex-C, and Hex-t. There...
