The data displayed on the Ensembl Fruitfly site is a compendium of data
from different sources: The euchromatic sequence is based on BDGP
assembly
release 4,
whereas the annotations of the euchromatic regions displayed in Ensembl
are based on data imported from flybase rel.4.3
(dated
20060130).
For the heterochromatic regions sequence was provided by DHGP (release 3.2). The annotations on the heterochromatin are imported from gff-files published by flybase (release 3.2b2, dated 20050110). No additional gene build has been carried out, however repeats, blast hits from the Swall database and protein features have been computed through the Ensembl pipeline.
We have included Drosophila into the Ensembl system to allow people to access the Fly genome through the Ensembl user interface (both for visualisation and data mining) and to provide cross-species integration throught our comparative genomics resources (such as homologous gene links and family pages).
The canonical data for Drosophila is managed at FlyBase and we are working in partnership with them to provide feedback on their resources.
There is no Drosophila melanogaster-specific news this release.
