Abstract

Drosophila guanche is amember of the obscura group that originated in theCanary Islands archipelago upon its colonization by D. subobscura. It evolved into a new species in the laurisilva, a laurel forest present in wet regions that in the islands have onlyminor long-Term weather fluctuations.Oceanic island endemic species such as D. guanche can becomemodel species to investigate not only the relative role of drift and adaptation in speciation processes but also how population size affects nucleotide variation.Moreover, the previous identification of two satellite DNAs in D. guanchemakes this species attractive for studying how centromeric DNA evolves. As a prerequisite for its establishment as a model species suitable to address all these questions, we generated a high-quality D. guanche genome sequence composed of 42 cytologically mapped scaffolds, which are assembled into six super-scaffolds (one per chromosome). The comparative analysis of the D. guanche proteomewith that of twelve other Drosophila species identified 151 genes thatwere subject to adaptive evolution in the D. guanche lineage,with a subset of thembeing involved in flight and genome stability. For example, theCentromere Identifier (CID) protein, directly interacting with centromeric satellite DNA, shows signals of adaptation in this species. Both genomic analyses and FISH of the two satellites would support an ongoing replacement of centromeric satellite DNA in D. guanche.
