Drosophila melanogaster assembly and gene annotation


Ensembl uses the Berkeley Drosophila Genome Project (BDGP) assembly release 6 (July 2014). In contrast to release 5, regions without a chromosome assignment are stored as distinct scaffolds, rather than on a single pseudo-chromosome, and heterochromatin regions are incorporated in the chromosomal arms.

Gene annotation

Protein-coding and ncRNA annotations were imported from FlyBase, release dmel_r6.32 (FB2020_01).

This species (and other invertebrates, including 11 other drosophilid species) are also available from our sister site, Ensembl Metazoa
