Drosophila sechellia Assembly and Gene Annotation
About Drosophila sechellia
Drosophila sechellia is endemic to (some of) the Seychelles, and was one of 12 fruitfly genomes sequenced for a large comparative study . D. sechellia is useful for research into speciation because mating with D. simulans produces fertile females and sterile males . Ensembl Genomes imports data from FlyBase, who also have much more information about the biology of Drosophila sechellia, and a phylogeny of the 12 sequenced fruitfly species.

This is the October 2005 genome assembly of Drosophila sechellia. The 4.9x whole-genome shotgun sequencing was performed and assembly provided by the Broad Institute.
Protein-coding and RNA genes were imported from FlyBase, release dsec_r1.3 (FB2017_04).
Repeats were annotated with the Ensembl Genomes repeat feature pipeline. There are: 227,447 Low complexity (Dust) features, covering 17 Mb (10.3% of the genome); 68,547 RepeatMasker features (with the RepBase library), covering 30 Mb (17.8% of the genome); 77,058 Tandem repeats (TRF) features, covering 15 Mb (9.0% of the genome).
Protein domains were annotated with the Ensembl Genomes protein feature pipeline.
