Drosophila ananassae (Fruit fly, TSC#14024-0371.13) Assembly and Gene Annotation

About Drosophila ananassae

Drosophila ananassae is a useful model organism for genetic studies because it is easily cultured in the laboratory, and was one of 12 fruitfly genomes sequenced for a large comparative study [1]. Ensembl Genomes imports data from FlyBase, who also have more information about the biology of Drosophila ananassae, and a phylogeny of the 12 sequenced fruitfly species.

Assembly

This is the August 2005 genome assembly of Drosophila ananassae. The 8.9x whole-genome shotgun sequencing was performed and assembled by Agencourt Bioscience.

Annotation

Protein-coding and RNA genes, which were annotated with the NCBI eukaryotic genome annotation pipeline, were imported from FlyBase, release dana_r1.06 (FB2018_04).

Repeats were annotated with the Ensembl Genomes repeat feature pipeline. There are: 409,506 Low complexity (Dust) features, covering 30 Mb (13.0% of the genome); 122,490 RepeatMasker features (with the RepBase library), covering 64 Mb (27.5% of the genome); 173,334 Tandem repeats (TRF) features, covering 39 Mb (17.0% of the genome).

Protein domains were annotated with the Ensembl Genomes protein feature pipeline.
